Hello All

Is the inner wings suppossed to be printed with support? (due to the top layer cap) at any place I read that is needed. thks

Nevermind, i bought you coffee and got the pdf manual

How do you assemble without glue?

Hello, i accidentally done it with 2 perimeters and 5% infill (wing) i did all and then realized my mistake, it is super solid but each wing part is about 100g, i am thinking of making the canopy and front and back parts lighter with only one perimiter?

Put a big motor!

2212 2200kv enough???

Other 50g?!
The problem is the launch. To me if you use the rubber band and a catapult should work

I was thinking pvc pipe launch slingshot

I never seen! I'm stay tuned. Let me see

Are there any instruction for V7 as there were for V6? I am looking for sizing of rods.

Hi just about to print can I use .06 nozzle as it will half the printing time any suggestions on settings for .06 extrusion thankyou

just printing the last part all together with 4s bat. it has over 900g- bat.is only 150g . PLA had some infill 3- 1 on ext. wing part which i did PTG

I stay tuned to see the evolution! I never seen a GASB One 4S powered

Just finished printing this and it looks great! Is there an assembly guide video ? If not, then any advice/directions for putting it all together? Sorry if this has already been answered.

No there is not request a sequence. Usually I start from the wings pay very attention to the allignement and to the aileron functionality. Please, when you finish the mountage, can you post a make here and if you want in RcGroup forum? Thanks for your comment. Ciao Carlo

Comments deleted.

I have noticed that the Aileron seems to have some model issues with the Servo Horn. I have since loaded the file from v6 into tinkercad to remove the inner supports as to load the model into Cura without any internal structures and am printing it with 6.4% Quarter Cubic Infill to make support for the holes. should be about 16g. will post if this is successful.

In my latest model Instead tp print the horn in the aileron I preferred to put a cut in oder to use your favourite commercial horn. I tried to put in GASB 3 all improvement after my experinces and suggestions by the users. For example all parts are fixed by screws and included the fousolage. GASB 3 is my plane make better. Ciao e grazie for your comment and I stay tuned to see your remake. Carlo

I like your idea a lot. could you share the STL with the cut made in the aileron. I am very new to modeling. im sure I could just put a hole in the wing where the horn is correct??

Can somebody got me Cura 4.1 profile to print GASB one?

what settings to use in slic3r to get good endurance and lightness?

For lightness: 0% infill, thin width
For endurance: 100% infill
You always have to compromise. If it weighs more you will also use more power to reach the same speed, so that means shorter flight times. I'd recommend trying out different settings and trying to bend and press on it. You could also just print it and make the parts that break stronger by printing them again.

Hi, I have just finished printing an outer wing with my new ender 3 and it is basically ok, but it is covered in ridges about 1mm high ( see attached photo) and the wing skin is not attached next to the ridge in some cases . Any suggestions please ?, I'm quite new to 3d printing.


Can I get the design data between the wing and the body? I'm trying to put a flight computer in the body, but there is not enough space. So I want to make design by my self a body,

Hi guys,
do you use infill also for wingtips and ailerons or just for center part? I have problem with printing single perimeter without infill - my airfoil is warped. What can helps is infill, but with high value infill it will be heavy... How to fix this warping? I use prusa Slic3r, heat bed, extruder fan, my print speed is 60mm/s, but I tried also 30mm/s with same result.

what infill pattern?

I use grid.I prefere the infill generated by Cura engine because the one generated by Simplify some time double the perimeter

what shell settings?

i noob english sorry

How do the servos get secured in place? i don't see in the instructions. :)

Two points of hot glue

Where do you guys get the carbon rods and the other parts from? Thanks!

Carbon rods in the shop of modelism in my city, instead the rest on Aliexpress

thank you! Sadly, we don't have hobby stores around anymore. they have all closed. so i'm trying to find all this online. its challenging!

Yes is almost the same here. It is a terrible moment for this hobby. The online shop have destroid the local shop. Unfortunately the carbon rods are difficoult to ship from china. Maybe there is something in Dechatlon store used for kates

Hello, I question, I saw RcLifeOn´s video and he says he had to cut a hole and move the battery to the front of the plane because the center of gravity was being a problem, has any of you guys had this problem?

Ciao Sebas,
sometimes, some one, has some difficulty to respect the CG. This os due to the weight of the print. In general, to avoid this you have to use the longer nose.
I hope you enjoy with my plane. Let me know :)

Thank you very much for answering, I just have one more question, I would like to know what ESC you used for your plane.
The thing is that I am new into this world of RC toys, so I watched a video on what ESC was the best for your motor, the guy said you need an ESC with about 10 or 20% more amperes in your ESC than the one in your motor, and I am using a motor with a max current of 13.6A, and the spec say the recommended ESC is of 20A. I just wanted to know what would be better for the motor.

Thank you very much.

This is the motor I am using: https://www.amazon.com/gp/aw/d/B01LSKYWY0/ref=psdcmw_2234129011_t1_B01LSKZXVQ

Can I please have the editable stl files for fusion 360? I would like to make it smaller as a remix;)

To make it smaller you can just scale the model in you slicer, but if you want to edit the model, what you can do is import the files to your Fusion 360 Project. Once you have the files in your project, open one of them, then go to the browser (the list of components on the left), open up the "Bodies" menu. At this point you should see a "Mesh Body" inside your Bodies folder, right-click on it and then select "Mesh to BRep", a new window will appear on the right side of the screen, then click "OK".

By now you have converted your STL file into a solid object, now you can edit it and play around with it, even though it works, it going to be a little hard to work with it. Remember to scale the object to .1, because when you insert an STL into Fusion 360, the dimensión go crazy.

I'm just trying to make the wingspan smaller, not decrease the size of the model. i am trying to use the loft tool, but there are thousands of little triangles, not a single face so that failed. i might not even try tho

If you want modify the model like that, you can use the "replace face" feature, it is hard to explain through this comment, but you can search it up. It is basically you create a sweep of the face you want to replace, then go to the "Modify" section and select "Replace face".

I think it would be easier if you watched a video.

What is used to join it together apart from glue?

You can use glue, but you can also avoid it using tape. to align the part, I use carbon rods 3mm diameter

What are the dx files for?

the wings are simmetric

You have to use mirror function in your slicer

The dx files are allready mirrord, right?

Yes it is correct. The DX files are already mirrored.

a great plane. Had my maiden flight today and it flies very well. definitely not a beginner plane, but if you are familiar with the flight characteristics of a delta it should be no problem. I recommend using good servos (fast, digital servos)

So far so good, the completed wings are 1g each under and the completed fuse is 1g over. Just got the Ailerons to print and I'm all done.

Hi, Here Is my cura default for this plane. Feel free to adjust these settings, Mine look real good so far!!!!!!!

Would anybody be kind enough to share with me the Cura profiles they have successfully printed the GASB with please? I'm struggling to get mine set up using an Ender 3 and Cura.

Many thanks

This is what I have made and the first pat is printing overnight, so fingers crossed!

Using that profile the rear printed fine. It feels very strong and solid but came in at 107g, so a bit heavy. Using Technology Outlet PLA at 210c dropping to 200c after two layers.

do I need ANYTHING except listed on pdf instructions? of course I know I need controller, but is there something more? Newbie to ac plane, dont have anything.

My Improvement of the fuselage for easier hand launch:

Whats different between "ali" and "ali_dx"?

This looks awesome and very well done. Would it be possible to get the STEP or SolidWorks files to edit this, so I would be able to customize the motor mount to fit whatever motor I choose and make other adjustments as needed.? I have access to a large format printer and wanted to try printing this out at 1.5 or 2 times the size. I would be sure to credit you and post it as a remix. Thanks so much again for the hard work that went into the design of this!

Hi all!
Many thanks to Carlos for this great project!
It looked like a very well thought out design, so I just had to have a go at it. I was not disappointed, the printing went very well and the GASB One was soon ready for the equipment. I did not have time to wait for parts from China, so I grabbed what I found in my drawers and boxes :-)
Details can be seen from my maiden video: https://youtu.be/I5Q535-lzKg
and my second video: https://youtu.be/PWg0boHlHqk
No footage from my last flight due to an unfotunate PC disk crash, but there is a photo...
I recommend this plane for all up to 70 years of age and beyond!

Changed the short nose to be able to put in a FPV cam and open space for bigger LiPo's to fit in as you see in my picture I have a 4S1500mAh Turnigy graphene battery, the short nose with the Antenna and camera in place was 10 grams more then the longer nose also linked in this awesome wing model from Carletto73

here is the STL https://www.tinkercad.com/things/0KECGOvOD6A feel free to redistribute if this worked for you

have fun flying

Comments deleted.

I would say NO! It doesn't appear to have the mixing capabilities for the Elevons.

Can you make a version that has a hole and mounts for an fpv camera?

Hi here is my attempt at adding FPV posibilitys on the short nose. I am printing one myself now and i think it will have a small issue with printing back side of the camera hole but it should be minor filament stringing the rest seems to build up properly


I'm done printing, "flew" it already, and it just went in the ground with no height rudder and with like 1mm it went straight up - crashed - does this model require a bit of height rudder or are they supposed to be completely flush?

Hi, cool project :) I am currently printing the newest version.... but I don't have the carbon rods, I noticed that too late - can I glue the newest version as well?

Hi, first of all thank you very much for this awesome plane files.

I printed it twice, the first time i tried to fly it it crashed. In my second build i used an FC and it flies perfect. I tuned it a bit to fit for my needs. Some specs: 150 kph (95mph) topspeed, up to 50 minutes of flight time, And Fpv support.
Here's a link to my video: https://www.youtube.com/watch?v=uc_uKN3bqM8


you have to share the flight! im trying too make it with the same specifications.

Hi ms2kTV

Last week filming the video I've had a crash due to a malfunctioning Servo. I'm currently printing the missing pieces. I'll post the link and the video next weekend

whats the raw weight on your wing? (before any electrical parts) im printing my last 2 parts now but i am also 100% sure my weight is over the 550 grams in flight order as suggested or given in the manual by 200 grams but im gonna use Graphene Panther 1600mAh 4S 75C Battery Pack in order to compensate the 200 grams.

hope to see your video soon

added a picture of mine in progress

Nice painting on the front
I don't know my printing weight but my flying weight is 820 grams. But it flies perfectly.

yeah thats i guess my weight too.. you use what type of LiPo? i doubt the 3s will deliver, but my ESC/motor can handle 3s/6s so i have a wide range of testing

I have posted the link in the main Comment.

good job

I'm using a 4s li-ion battery but with 3s power it would fly.

very nice
i will try it from today on
how long will it take to print???

Hi ! Maybe you are interested in a common development of a Nuri made of cut foam .... Your project is really outstanding. Everything constructed yourself ...?

will a 2200KV Brushless Motor A2212-6 with a 30A ESC work?

this motor is heavy I think 50g. Maybe you must use the longer frontal part instead the standard one to fix the cg

Can anyone recommend a good infill percentage for version 7 that balances weight with strength?

to me 3%. if you use more the weight is too hight and the cg il too rear (in this case you need the front longer or add lead in the point).

to me 3%. if you use more the weight is too hight and the cg il too rear (in this case you need the front longer or add lead in the point).

All my parts came out heavier than what you listed, and I set all the parameters as they are listed in the build instructions. also the CG is not that great, I put the ESC, Battery and receiver all at the front and it is still tail heavy ... I noticed you have a longer nose piece , why is there a short nose if that is not ideal for proper CG ?

Many people print too heavy and is why I created a nose longer in order to respect the CG.
In any case if you print more light you can use the standard one as you can see in several videos on the tube
I don't know with the same parameters the weight are different maybe the flux is not correctly set

Thanks, It would be helpful if yo perhaps provided the Cura Profile for the prints. the user can adjust nozzle size if it is different, I st the parameters as per your instructions, and this is what shows up on my Cure see attached, I adjusted I adjusted horizontal expansion and this seemed to fix the problem but i think it added weight, Horizontal expansion 0f .1 uses 21.45 m of filament , .2 uses 27.44m

There is obviously some setting that need to be set in order to achieve the weight results you provided, I have finished the plane version 6, and to me it feels too heavy for the motor I am using. Can you advise ?

Has anyone tried scaling this plane and printing at 150% scale?
I have a Creality CR-10S and want to try it, but so far it seems the weight for external wing goes from being 46g to 136g.

Hi, great design, cureently in the middle of printing :D I will be using older repurposed miniquad 2205 2300kv motor with this, ideally i wanted to go for 2s and 7inch prop but it looks like it wount take more than 6inches. Or am i missing something ? Thanks.

I don't think that 7inch propeller fit into the model. I use 5 and 6 inch propellers

What Controller should I use???

I don't use any flight control. Just receiver connect to servos and ESC.
The model is very easy to pilot

Anyone tried to go down in size? May be 11xx sized motor?

Thanks for this awesome plane!
I made the stl's for printers which are a little bit smaller.
If anybody is interested: https://www.thingiverse.com/thing:2823068
I will post a made if a finish the plane.

GASB One from Carletto73 files for small printer, eddited with OpenSCAD

some remixe for FPV cam?

i came here to ask the same question

Maybe it's a noob question but this model would be the first 3d printed aircraft for me , so...
Why do you suggest to print it with PLA instead of ABS?
It's only because of the ease of print or for mechanical reasons?
ABS should be lighter, stronger and can be easily polished to have a smooth surface.

Yes the reason is because is more easy to print. Up to now I saw that in ABS printed model there are some delamination. I you want try it will be apreciated

Hey Carletto73, at the moment i'm printing my third plane of your's. Again big thanks for sharing your model! :)

One question, i want to make the with fpv gear, would it be possible to get the canopy source file? Remixing stls is.. :)

Love to print this but my Flash Forge Creator Pro 2016 is just too small by about 10mm

Ciao Carletto,
I have experienced rev 6 , great job , very semple , few parts .
I have good experience in flying rc model , this model is my first experience with printed model , very exciting !
I had problem in weight , 800 gr , and in barycenter , I modified the front part to move the 3S 2200mAH battery forward, I added a strong hook to let the take off by a elastic .
to compensate for the weight i used a SunnySky X2212 1400 kV motor with a foldable 9x5 propeller.
I made three flights , during the last I experience a stall , corkscrew and crash.
Since I expected asymmetric wing stall i added turbuletors on the external wing but it did'n work
What is your experience ? have you experience the same catastrofic event ?
To overcame this problem I want to made a project change and apply a negative twist to the wing , 3 degree , in order to prevent stall of the tip of one wing ?
What do you thik ?
To do this change i need to made a new model of the wing , for this scope may I know which is the wing profile have you used ?
Generally speking I have found a lot of informations about how to print your model but very little about design of the model , example have yoy used xflr5 or otrer means to define wing cord , wing tapering ,wing swept , etc ?
Best regards

Ciao Roberto,
il modello è basato sul profilo del progetto Zagi 10. In rete puoi trovarlo facilmente. Normalmente io stampo più leggero e non ho problemi di baricentro o di stallo. Nello sviluppo del tuttala ho rotto diversi modelli soprattutto all'inizio, sia per inesperienza nel lancio a mano, sia nella ricerca del baricentro. Adesso il modello è molto stabile e difficilmente crasha. Se ristampi ti consiglio di usare la revisione 7 che ti permette di montarlo senza colla in modo che ristampi solo la parte che ti si è rotta.

Hello friend, you look like you have a Hobby King store in those boxes haha ​​... why do you say you do not recommend to start in radio control with 3D printed aircraft? T for example in the 3Dlabprint store (https://3dlabprint.com/shop/) they sell planes of all kinds, including Trainers and gliders ..... I think it depends on the experience of each one ... personally I have a Trainer that I will try to fly this weekend, just that the engine does not arrive by mail ... is a beautiful field, is the yard of your house?

Is it necessary / good to use a flight control?
Which flight control do you use / are good and cheap?
Thank you

No it is not compulsory. I don't use a FC but i would like try to do. I saw a FC with take off landing. This can help to launch by hand.

How do I control this plane without a fly control.
There are three channels (left, right, motor). How do I connect them to the receiver.
Because I have the 4 signals of the two joysticks but I need a addition of them?
Thanks for your help!

btw - fast reply!

It is very simple. This is a flying wing standard applicatione. You have to use the mix "aileron" on your radio, and the aileron work for roll and elevator. Search on google and you will see that is very easy and commun

I will check if this is possible on my (old) remote control.
Thank you

I am planning to make a V7.

Is it possible to print this with a 0.4 nozzle?
I only made the canopy so far. Simplify3D showed me 23 gramms instead of the suggested 19 gramms.
It came out quite fine. The top layers on the canopy are a bit thin maybe. I can see light shimmering through some lines but the canopy is sturdy and usable.
What settings would you use to print it with a 0.4 nozzle to not get completely overweight?

Did the version 7 kept the 9gr servo holes ? Can I use the Body of the V6 and the rest of V7 (Because it says that another wing profile is used so I not shure about that).

But if you use the V6 Body, you can't use the carbon rods to connect everything together.

Right. You can use body rev 6 and glue or rev 7 glueless

Yes you can use the body of 6. Same wing profile

Hi carletto,
Thanks for your job

you are welcome :)

Really cool design! I am printing mine right now.. would be neat to have a canopy with a camera mount for fpv!!

I'm working on it

Did you finish working on the fpv canopy yet?

Unfortunately I'm switched on other prj

Great! I was trying to make a version of the front piece to accommodate an fpv camera but my 3D skills are miserable!
When are you thinking of releasing it?

Tried someone to scaled it up?
I think I will first print them in original size, but later maybe 1.5 or 2 times bigger, depends on what will fit to the CR-10s.

Would there be a problem?
I know, I need adapter for motor and servo mount to fit again.

Hey, would it be possible to do a version for a 2204 motor?
There are a lot more common - at least here.
This would be so great.. so I don't need to order them from China

edit: Okay, saw your post, that it will work. =) cool! Maybe you can put that in the description :)

Flown it now in severe wind conditions 4 to 5 bft.
It survived due to the Frsky S6R i borrowed from a friend. (Receiver and gyro)
Works amazingly well on a teksumo too...
I replaced the canope with a yellow one , so i can see if its up or down...;-)

Great !!!
Very useful this receiver with integrated gyro

Merry Christmas

Merry christmas to you Carlo!
I am curious of what kind of lipo do you use?
With my 1300ma nanotech i have to use 75 grams of lead in the front to get a good balance...
Saw it in your manual...sorry...:-) its a 120gram lipo..

Started printing with the V7 , can't wait to fly it !
Thank you for the great design!

I have started printing the main body and have one issue/suggestion i have noticed the 30mm mount for a fc would making the holes m3 sized so a nylon screw could be glued in not be better than the holes that currently require drilling to fit an m3 screw

Good idea! Thanks i will do as soon as possible

ciao Carletto
io uso una Prusa originale mk1
mi sai consigliare quale velocità impostare ?? ( 60mm/s ??)
per lo slicer ritieni più valido cura o simlify3d ?
non vorrei buttare via ore a vuoto....
grazie e ciao

Ciao. Se stampi l'ultima versione (la 7) è indifferente. Altrimenti se stampi la 6 meglio cura. Per la velocità non è critica più piano vai più esteticamente è bello il pezzo

Ciao e grazie per la veloce risposta...
quindi se imposto a 60mm/s dovrei lo stesso riuscire ad avere un buon risultato... bene..
questa sera imposto e parto... grazie mille.. ti tengo aggiornato.

How do you mount the servos? double stick tape?

Hi there,

I can help but noticed that that are 4 standoffs-like mounting slots on the rear section of the fuselage, are they for a purpose we should know about?

Do you refer to the holes to fix a flight control?

I'm not seeing the "bayonet" 5mm carbon fiber rod in the manual photos. Where does it go? Is is a single 615mm piece?

Yes. It's just a single piece and passes through all parts side by side

Printed this on a Creality CR-10. At first i had issues whit the wings,but swapped to the solid files for the wings and came out great. I am using Simplify 3d as the slicer program.

Nice! What transmitter and receiver would you suggest?

is up to you
I use an old turnigy 9x remote controller

Released version 7.

Made with the great help of Marco67. No need glue to the assembly, just carbon rods and adhesive tape. In case of crash, allow to disassembly and repair just the par demaged. Wing made as solid without internal structure, allow to use the setting prefered by the user also also more easy to print.

Hi Carletto, thanks for this great project!
A request if possible, could you release a version of the wings without the internal structure, obviously leaving the servos base/bay and the holes for the ailerons, like "GASB V5"?
I would try to use a personal infill, with "fast honeycomb" at 4% i've really better results with another project.
I use 0.4mm nozzle, 0.2mm layer, two perimeters 0.2mm and unfortunately S3D during slicing produces an unwanted effect, see picture.
Same result with only one perimeter at 0.4mm.
I would like to be able to slice and print it with one perimeter (0.4mm) and fast honeycomb infill at 4%, using 0.4mm nozzle size, like with "GASB Release 5", but with your others great improvements of the V6.
Another request: the servo's housing horizontal print just two layers, could you reinforce it at least 0.6mm (3 layers)?


Many thanks Marco for your comment.
Here https://www.thingiverse.com/thing:2634350 you can find the models of the wings in solid version.
I hope can help all guys that are soffering with their slicers

Hello again Carletto73.
I have read somewhere on the net that to calculate what motor is required to drive an rc aeroplane, it was stated, take the rc aircraft total weight, and find a motor that has a thrust amount in grams, more than the weight of the total aircraft weight!
To me it seems a good theory, reason why is that using your motor and prop for this 3d printable aeroplane, the motor specs state that for an 11.1 volt 3s battery and your chosen propeller, you can pull 390 grams thrust of weight, and the total of your printed rc aeroplane with all parts come to 358 grams, hence your plane can still pull that 358 grams and is still fast enough from the videos that I have seen of your plane in action.
What do you think regarding this theory ? To me, it seems that if this proves to be true, which it does seem so to me so far, then its the easiest way to calculate what motor you need and if it will be strong enough to carry the weight.

Good day to you Carletto73 ...
Firstly, Thank you for your hard work and distribution on this printable rc plane, I am really looking forward to printing it soon.
Secondly, can this rc aeroplane be scaled and printed to a smaller size and will it fly ?
Thanking you!

I've try to do something smaller but I can tell that the minimum in this tecnology seams to be 80cm span. Smaller is too heavy

Good evening once again Carletto73.
I was meaning to ask you, according to these specs for the rc aircraft...

  1. DYS BE1806-2300KV motor and
  2. esc Flyfun 12AE (12 A with BEC)
  3. a 3s 2700 mah 20c lipo battery

Is it possible to calculate the flying time at full throttle when using the above specs as the rc aeroplane ?
Thanking you !

To me 2700mAh is to heavy. I flight t sigh 1500mAh and I male flight time is around 7-8 minutes

Just calculating something....do you get this 7 to 8 mins of flight time at full throttle with the 1500 mah battery?

If yes, then do you think that you should get around 15 min at half throttle flying with the same battery ?

Thanks for your prompt reply Carletto73!
Ok, heres what I am trying to do, I am planning to use this printed rc aeroplane for long distance fpv, about 5 km in distance. I have already researched on the autopilot, 2.4 ghz signal booster and the transmitter and receiver.

Here is something that I would to let you know regarding some light on what I currently have and tested...

I have a bayangtoys x16 quad/drone, this drone comes with an 11.1 volt 3s 2200 mAh LiPo battery, but my battery was damaged, so I used my old cheerson cx 20 battery which is the same 11.1 3s volt 2700 mah lipo but with 500 more milliamps. Flying this drone, I get around 14 to 16 minutes of flight time, mostly moving but some hovering as well. I also have a 11.1 volt 3s 4200 mah lipo battery which I also tested on this bayangtoys x16 and it gives me 18 minutes of flight time, just two minutes more, the reason is simply the weight of the battery, even though its 4200 mah, the battery is much heavier and so it only provides 2 minutes more of flight time.
The bayangtoys x16 quad/drone has x4 2212 / 900KV motors and x4 20A Brushless ESC's. With these motors , esc's and the 11.1 volts 3s 2700 mah battery, I get around 14 to 16 minutes of flight. The drone weights 569 g without battery, with the 11.1 volt 3s 2700 mah battery, it weights 789 g total weight. This battery weight alone is 220 g. Using this info, I am sure that we can calculate a rough estimate of what your 3d printed model weighs and then have a good idea.
Perhaps we can use the same setup for this 3d printed aeroplane somehow ?

What I would like to know is...

Perhaps we can use the above motor 2212 / 900KV or higher KV motor type with the 20A esc and 11.1 volts 3s 2700 mah battery on your 3d printed aeroplane to get good flight time ?

What battery setup can we use to reach 5 km without eating all the battery on the aeroplane and still have enough battery power to reach 5km and do some fpv for an hour or two hours, if possible ?

Figured out the problem people are having with the wall of the wing not showing up. use a setting called "Horizontal Expansion " i used a value of .1 to compensates for the overly thin walls. also it still prints at the correct weight. it is located under the shell tab

Yes this fix has worked for me - Cura 2.6 - was have the same problem many have had below in the comments but the horizontal expansion has worked for me! First one printed and now waiting for chance to do the maiden. Having flown the GASB ONE on a EMAX 2204 motor for a bit of extra power I have gone for the EMAX 2205 motor with this one. Main reason being I can't get the weight as low as suggested. Carletto states printed parts 360g in total - mine 400g, plus maybe due to the extra weight and bigger motor I need a 2200mAh pack to get the CofG correct. Hoping this won't be an issue as pulling 200W of power on a 5x4 prop.

My GASB ONE is over weight as well!

Went for the 2 perimeter print for the wings as well, although with a 0.4 nozzle and wall thickness set at .3 seemed to give the best balance! Albeit as said slight over weight. Interestingly the front and rear were a couple of grams under weight following the setting I had from the GASB ONE prints

Im setting up to print this plane and the internal part of the wing doesnt show up very well no matter the infill setting

Plane looks great! Im printing mine at the moment. How about designing a speed 400 style pylon racer? Would be cool with a really fast 3d printed plane :)

Could be an idea for Gasb 3.
Can you show me what you mean exactly?

Awesome :) Im currently working on one myself, but I dont have the same skill you have! Something like this: http://www.electrifly.com/discontinued/gpma1805-views-b.jpg

I have the same Problems with the shell in Cura...
I tried some settings and when i write for example 0,01mm in the
parameter "Horizontal Expansion" then the shell looks very well...
Maybe that's the solution of the problem with these holes and gaps in the shell.

Please leave a comment if you test these setting...

Yea It was driving me absolutly nuts but I read the thread and did what you said and it did fix it but my question is why would I have to do this at all ..is it that the person taking credit for the gasb made a booboo and why hasn't he then updated the wing files to fix this instead of leaving a bunch of people with a pile of unusable pla scraps.lol any ideas?

Please in case of issue on wings printing visit https://www.thingiverse.com/thing:2634350
This models are exactly the same of the original but without internal structure. In this way you can set thickness and infill as you want

Wings of GASB One release 6 - Solid models

Thank you very much!
Thats what im waiting for, i will try it as soon as possible!

Can someone that has had successes printing the wings send me there Files. I can get the wing to fully print for me, Cura is not seeing the face of the wing.


WOW i really LOVE this design.
Im still printing the parts.

But i was lucky ordering all required parts at Banggood Sale and got up to 11% Discount on almost every part:


Thank you soo much!

Hey people has someone a list what you have to buy? best with Links? Because I do not know which battery and what a rc? Thank you for the answers

I need some help on this one, Basically, i am not getting the shell I just get the structure of the wing but most of the surface didn't print just a mess. Is there a way to upload a pictire?

Printing on a Creality cr-10 that has been working great. Using 0.4mm extruder.
My settings using cura 2.6.2 while printing the outer wing are:
Layer Height: 0.2mm
shell - Wall Thickness 0.4mm

  • top/bottom thickness 0.2mm
    -top layers =3
    • Bottom Thickness = 0.6mm
    • bottom layers = 3
      Infill =0
      Material temp 210 (pla)

Retraction distance 6.5
Retraction Speed 25
print speed 50mm/s
travel speed 120mm/s
Cooling enabled
fan speed 100

I think the walls are trying to print to thin.


i have the same problem. Do you have a solution for this ?


GASB is nice plane~~very good...

GASB1_06_int have bug...

I don't know what do you mean.
The shell thickness (in the drawing) is 0,4mm

My setup is:
Nozzle 0,35mm
I print the wing with thickness 0,2mm, so the printer make two perimeter. The material used is the same of one perimeter of 0,4mm but is more robust
Top 6 bottom are 3 layers
The layers are 0,2 mm

I don't know other slicer except Cura that allow you to se one perimeter 0,2mm with the nozzle 0,35mm. Also I don't know the setup for other nozzle diameter


Thank U...It's ok~

Im having bugs with Gasb1_06_ail, but I ain't complaining.

JK, Carletto stopped responding to my comments because I had too many questions.

i think u can try using Magics software to check files GASB1_06_int.stl errors...

Thks.i use cura slicer is error "Overlapped triangular patches",but use Slic3r is OK.

(Only GASB1_06_int model)

Sorry for my english...my english is pool...hehe.............


IS that will all the wing files? I cant get any of them to print right.

No...Only GASB1_06_int model error ....

cura 2.6.2

has any body fixed the wing print issues? Every time I load it Cura is not see the outer skin of the wings. Ive tried different versions of Cura and Still no dice.

Have you tryed with perimeter of 0,2mm. In this way the slicer make 2 perimeters

Perimeters??? Are you talking layer thickness?

Yes I mean layer thickness

My setup is:
nozzle 0,35mm
layers thickness 0,2mm
top and bottom 0,6mm

Could I request that you make a secondary option for the wings to be solid; with no internal feature, so that those of us who are experiencing the perimeter problems can print the wings with ease. Other than that it is a great design.

Oh, and for those of you who are using simplify3D like I am, I discovered that if you go under the extruder tab in the processes pop-out, look for extrusion width, change to "Manual" and change to 0.2mm.

Perimeters are not layer thickness.

Layer thickness is how thick (vertically) the layers will be as they are applied to the bed.
Perimeters are the number of outside perimeters lines that are used before it starts on infill.

Still No luck for me

Hi VPC Tech,
when you go to ultimaker.com you can now download the new cura version 2.6.2. It's no problem, you have just to go to
products=>software=>cura software and than you can simply download it.

me to~~GASB1_06_int.stl right?

Thanks for the tip Robaer, I would not have checked for an update because my Cura 14.07 clearly sounds like its newer than 2.6.2.. also within Cura it has a 'Check for updates' link in the toolbar and it said i'm running the most current version. Oh well. Live and learn.
Cheers all!

First off... Carletto - this thing looks amazing.. however I'm seeing the same issues as several other people are having with the ails and wing pieces. When I look at it in layer mode in CURA, the walls are not seen at all. It's only if I jack up the shell thickness and top/bottom thickness that I am able to see the walls, but they're FULL of holes and gaps.
Was there any solution to this?
Also I'm using CURA 14.07. ... I don't have a clue what people are talking about when they say Cura 2.3 or 2.4.
Any help from this great group is greatly appreciated!

I tryed to make one. canopy, front and back printed perfectly. But when i start to print the wings, it didnt work.
I printed on my Prusa I3 Hephestos with 1,75 PLA Filament. I think the walls are to thin to print, because i have some "holes" in it.
Same at the ailerions, the printer didnt want to print the wall. He didnt move to the spots where he have to print, so i have the so called "holes" in the wings...... Is there any configuration in cura to help me? Tryed to print in 2mm wall thickness didnt help, try to print with 100% infill didnt help, support structure didnt help........
Can anyone help me? I really want to finish this project.
Please excuse my english, im german, i hope you understand what i mean.

i have the same problem ...
Do you still have a solutuin for this problem?


Please try to set perimeters 0f 0.2mm in this way the slicer make 2 perimeters and it is more robust

I recently went to try and buy the mechanical pieces for this, and the people at the store made a whole bunch of questions, so I know I said I had one last question, but these are technically not mine;
-What servos do I use (like size and everything)
-What sort of Propeller do I get
-Can I add wheels (actually, that one is mine, if I can't add wheels, I'll make a small base with wheels so that It takes of moving but the wheels are not in the plane later)
-Where'd you get your pieces (probably an European or Italian site, but I don't care just want to know the specific pieces to compare)

Instructions on new V.6 is needed. V.6 is totally different from V.5. There are NO WAY to get front part weight of 27g, if you follow V.5 instructions. Even if you don't, and use shell thickness of 0.32 (instead of 0.5), its about 44g min. I got correct weight for back part (53g) if you use V.5 instructions, but seems like its not quite correct for infill level.
Stuck bad on front part, so i could not check the wings. Anyway wing is also totally different (great internal structure design!), so i believe it is hard to follow V5 instructions again. 0% infill?
Canopy..... 10 g.... HOW??? 16g if i follow instructions again. I mean V5 instructions. 13g if i use 2 top/bottom layers.

Using Cura 2.4 to be max close to recommendations. Got 0.35 nozzle too. I had no problem printing and building GASB 2 (great edf plane).

Is it possible to get short instructions?
Shell thickness, infill level, recommended weight, solid layers of each part?

Thanx in advance!

i was going to start printing this when i noticed the weight difference then i noticed in the pics his weights don't match the weights in the manual ether. but even trying to hit the weights in his photos is hard to do something here is not adding up so curenntly in simply3d the ext wing panel the closest i can get the weight is 48 grams (pic shows 42 grams) and that is with a .32mm layer width and 2 top and bottom layers .2mm thick. by the way the 53gr you are getting look just like his photo

For the wings I use 0,2mm thickness in this way I will have two perimeters. Please don't care the weight the motor is able to manage the over weight

Hi, Have you actually printed the wings having generated the cutter paths from Cura 2.4? As per my below comment I can't get the wings to 'generate' properly. Any advice?
Thanks, FlyGuy75

Set 0,2 mm thickness in order to have two perimeters. I have nozzle 0,35mm diameter but CuraEngine is able to inject material slow to have 0,2 mm thickness

Hi. Recently started using 3d printers. And I use many things that others do because I'm not very good at modeling. I see that your model has only two parts that make up a wing. Could you tell me how to do the other part, or where to download it ??

Thank you!

Please use mirror function on slicer to have the model of the other wing

Hi cqc70,
Hope I have followed your question - There are six part files you download. Three of which are the wing - two wing sections and one aileron part. These need to be mirrored within your slicer software to get the 'second' wing. The other three files are the fuselage.
Hope this helps.
Have a look at the 'original' GASB ONE page for the instructions. https://www.thingiverse.com/thing:2320788/#files

GASB One - Release 5

Hi FlyGuy75,
i had same problems with cura 2.4 and 2.5. I installed the cura version 2.1 back again and than it goes.

Thanks Robaer,
I will have a look at this as currently running Cura 2.4

Help with settings on Cura 2.4 for the wings. It's not seeing the outer shape a one solid outline, just breaks it up into smaller lines with large parts missing? Set Wall Thickness at 0.4mm, Wall Line Count is 1. Can't seem to find the term perimeter within the settings - what am I missing?
Printed the GASB One V5 and flies well so looking forward to trying to give this one ago.

One last question before I leave you alone: do I superglue the pieces together or what?
thanks in advance and sorry for bothering you so much with these questions.

Yes you have to use can anoacrylate glue

yup that will work if your using PLA, for ABS use a solvent based cement for best results

For REAR, I have ANET A8 Buse 0,4 and I Use CURA with

Layer Height = 0,2
Top/Bottum Thinckness = 0,6
Infill density = 3%
Infill Overlap = 15 %
Speed = 20 m/s

But Duration is 12h
25 M PLA
and 12 to print

Can you help me


Just tried similar settings on Cura and yes comes out close to the time and material used you say.
Main thing will be down to the speed you can run at and still get a good print. If you can increase the speed the time will come down by several hours.

What slicer have you used? I tried to print the canopy using Slic3r with the recommended settings (0% infill, 1 perimeter, 3 top/bottom layers, .2 layer hight) and the Slic3r program leaves big gaps in the top layers of the canopy. I can only get it to print with some infill.

What are the recommended speed and temperature for printing? I've used 20mm/sec for speed and 210C for temp and that seems to hold together nicely.

Yes canopy needs some infill.

I have a question: Where can I get al the materials for the RC? and what code do I use? I'm stuck. I know how to build it; that's easy enough, but extra pieces such as anything to transfer data from a Remote Control to the plane is blank to me. Do you have any instructions specific to that? It's my first time building one of these.

If you are a beginner please start with some of more durable. Something made in EPP

This new version seems very nice.
How much room do we have for battery ? (max battery size would be perfect).

The central part is fully empty and can be fit also a 2200mA 3C

What are the non-printable parts to buy? Radio control, servo motors, motor, etc ... do you have a list with references ?

See the manual pdf of Gasb One version. Only difference is the servo 9g

What sort of motors does it use? Where can I buy them? Also I'd like to know if there's a way I could add a name on the top or something, If not, then I'll just paint it using a stencil

It works with the most typical motors up to 200W (1806, 2204, 2205, 2206). I hope to see your made

I'll do my best right after my current project: fixing an old RC tank (as in war tank)

Zdravím. Rád bych si deltu vytiskl, ale chybí tam části křídel a křidélek. Nejsou rozlišeny levé a pravé komponenty. Děkuji

The parts arent missing. Just you have to slice with mirror function.

Jak, nebo v čem se to prosím dělá. Děkuji

Hi, thanks for this it's just incredible! but could you send me original files of this model ? Solidworks ? Freecad ? (obj file or other .. )


Cf: cam@mariaweb.fr

I'm sorry I don't share the original file. I am i program to collect every request and i will made a new version.

I suggest adding a few carbon bars to avoid the glue and thus to be able to change parts after a crash (carbon bar fixed with small screws on each side of the wing for example)

I'm also adding FPV support camera (foxeer HS1177) and antenna hole

what do you think ?

Like this for example

It flies!! I am very happy with the GASB-One. I am glad I made the elevons longer, very nice roll rate and good elevator control on landing. I think my CG is still a little far back so I will adjust and try again in less wind.



Flying wing - Mod from GASB One

Congratulation !!!
Your version is very nice to see and it flies very well.

Carletto, can you tell me... is the CG 28mm behind the "bumps" on the bottom of the wing?? The bumps are very confusing because I thought they were the CG marks but I read that the CG is 145mm back/behind the leading edge at junction of nose and wing. Ciao!
(I almost flew my wing today but when I measured from your instructions I see that my balance with the battery is very nose heavy. I have to put the motor back about 30mm)

Please use the mark under the wings. These are well positioned. This configuration is stable and motor is ok in this point.

OK, thanks. That helps. I will balance at the "bumps" and let you know how it flies. I am running a 2204-2300kv on 3S and 5X5 prop. https://www.amazon.com/gp/product/B01KJ717NW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1


Which glue do you use for assembly your model.
Have you some ref ?

Cyano acrilate medium or standard

Hey, how did you designed this? maybe can you provide STEP or Solidworks files as i would like to do some modifications....

Hello, I just added my modifications to this great design. I have it printed but not flown yet. I added longer elevons and stretched the nose for better CG. I will make an FPV nose soon. Enjoy!! http://www.thingiverse.com/thing:2048513

Flying wing - Mod from GASB One

Looking much forward the the FPV nose version :o)

Hello Carletto!
First I want to congratulate and thank you for sharing this model, and second I want to ask you a favor, can you share me the original source design to make some modifications? I'll give you your design credits.

hi, i modified your files to remove the extra margins and proper orientation for printing, let me know you email so that i can send you the files and i think it might be a bit helpful.


Do someone managed to slice "05_int.stl" with Cura ?
Cura gives me an error saying that the part is too large (I don't know how to force slicing)


hi pingouin000,

i made the whole flightwing in cura. maybe your scale does not fit? and the settings at "special modes" must be "one at a time".
the cura version i use is 2.1.99.


Hi Robaer,

I don't know why, but it works with the "9g remix" by cerro94 http://www.thingiverse.com/thing:1807171/

I will print with the 9g servo version as I prefer 9g servos over 3.7g servo.

Thank you !

GASB One 9g servo remix
by cerro94

Hi Carletto!
I was wondering why did you use PLA instead of ABS? ABS supposed to be much lighter? Did you try printing the plane with ABS?

I am interested in the results, 'cause I've a lot of problems with 'warping' when I print ABS, especially printing big things with a long print-time (like these parts). The material has time to cool down and than it 'bends' and loosen tight from the heating bed.

hi capone,
first of all, I'm not done with my tests, that's why I didn't respond yet. The preliminary results were disappointing, layer separation at it's finest with abs. I am however building a closed housing, I'll try again with that.

I never tryed ABS. I have only experience with PLA. In the begin I have read that the ABS is a little be toxic and as I print at home I prefer to use the PLA. I don't know if in the meantime something is changed.

All right, I'll print it from ABS then and post my results here.

great! thanks

Well, I printed them from ABS and they are much more heavier than your pieces. The reason being is that the material I'm using is not that rigid so I had to print 2 external layers.
That was only the first try, I'll keep you posted.

Good experence. Thanks I stay tuned :)

I give up, I couldn't get the stiffness and rigidity from ABS, so I'll stick with PLA.
I'll post my made picture as soon as I've printed it.

Great work, just printed mine and came out nice.
Just a question, what motor / prop / battery are you using?

In the instruction manual file you can find all informations

Hi Carlo!
Can you share source of front part? i want remix it for FPV.

Very well done.

(maledetto, ora mi tocca farlo)

Grande !
Mi aspetto di vedere il tuo modello volare!

Fammi sapere cosa ne pensi anche del GASB Two

GASB Two - The first fan jet fully printed

How put the infill in position shaft in ail detail?

The only requirement is that the infill must be located in the middle of hole for the steel rod that permits to the aileron to move

i understand. but how move infill to hole. slicer draw infil in middle of detail. how move infill from middle to hole?

Yes I use Cura. This slicer puts the infill grid in a fix place of the bed. In cura is sufficient move the object into the bed and re-slicer untill the infill grid is in the correct position


Is it possible that there is a scaling issue with the stl I have ?
I am in Cura 2.1.199 and the 05_int.stl seem to be too small :


EDIT : Sorry, it's me, Cura autoscale the parts ...


Ok. In fact nobody tell nothing about this.
Please when you finish pubish your made. Your pictures and video are what drives me to continue :)

For sure, this flying wing is a very great design !

Unfortunately, the rear part is too big for my printer, a Wanhao Duplicator I3, his maximum Z distance is 180.00mm and the rear part is 190mm.

Yes, normally in this case the user must split in two part this piece. For example Boris has your printer an as you can see in this make http://www.thingiverse.com/make:253494 he cut in two parts.

Hi Carletto,

I am using Ultimaker 2+ printer with a 0.4 mm Nozzle.
Can you recommend the settings for it?
The Wall Thickness 0.32 mm, Top/Bottom Thickness 0.6 mm, Infill Density 3% Infill Overlap 15% did not come out strong enough.
I appreciate your inputs to the correct setting for the above printer.


Hi beekeeper2020, i made some pieces with the um2+ and at my opinion are the settings ok but i setted the wall thickness
to 0.4mm and top/bottom thickness to 0.7mm.
and your printing speed? it should not be faster than 30mm/s and the nozzle temperature@220°C

Thank you Robaer!

I will give that a try.


I'm sorry but I haven't the Ultimaker (Unfortunately), so I can't help you. I can tell you that if the weight of your piece are the same of my piece I think that the robust must be the same. Weight and robust are proportional

Hi Carlo,
i love this project!!! i'm a big lover of my MPX Xeno but this is now my first project to handle.
thanks a lot for this.

Thankyou to you. Is a pleasure to me :)

Guarda, non so neanche se volerà o meno....
Ho fatto delle "piccole" modifiche al tuo progetto(uba sorta di castello motore modificato)... Per ora fa tanto rumore,ma voglio provarlo :P appena accedo dal PC ti faccio vedere che porcata ho fatto :P

Bel progetto, comunque

Non vedo l'ora di vederlo ;)

Hello Carlo,
I have problem with slicing this part because it's to tall and I have read the comments about it, but I still can't understand how to slice it in cura. The problem is that I can't choose to slice it anyway if it's to tall. By the way I need to say it's a great model!

I came up with a solution. I fixed the model in solidworks so now it is the same in all dimensions but without the problem that it's to high. :) The part if anyone want's it is here http://www.thingiverse.com/thing:1827304.

by Nivek11

many thanks. i hope to see your GASB One printed and flying :)
ciao e grazie

Hi Carlo,
first Try failed, but second one was printing during the Night and looks good now.
Result for Part 05_int:
43.7 Gramm and yours is 42.8 Gramm.
Seems it´s very close now :-)

Here some Details about Parameters for S3D and Part-No."05-int" the "inner Wing":
Nozzle: 0,35mm
Layer-Height: 0,2mm
Bottom and Top Layers: 3
Extrusion-Widht: 0,32 mm
Infill-Type: Rectlinear
Infill: 1%
Infill-Widht: 120%

The most different is the Infill-%, reduced to 1%.....
S3D creates a total different kind of Infilling and so it comes much heavier.
Actual i mirror the Part and print the second one.
After that, i go on with the other Parts and send more Information/Feedback here.

Some additional:
I had added some "Positioning Holes" on the Contact-Surfaces.
There you could glue some small Pieces of 1mm Steel-Wire, and then it´s easier to glue the Parts to each other.
The ones on the Bottom are perfect, but i need to optimize the upper ones.....
This will stabilize the glued Section of the Wing.

Good job
Nice idea the positioning holes. I will try and put in place in the next project
I to see you flight the GASB One as soon.

Hi Carlo,
seems i found the Reason, why some people have a different Weight ! (me too...)
It depends on the Slicer!
I use all your Parameters, but my Slicer isn´t Cura, it´s S3D (Simplify3D).
And the result is: Always heavier than yours....
347 Gramm only for the Plastic-Parts.

Actual i Print another one, with adjusted Parameters and a small Modification too.
It seems i could reach your Weight now.

if it´s a succesful Print, i post all Parameters and Details.
Printer is already running, but it will take few hours ;-)

Best Regards, Juergen

I think that can depend by s3d. If I not wrong in s3d you can set only the number of perimeters and not the thickness. is is true?
with cura you can set the thickness, for example my noozle is 0,35mm but cura is able to make thickness more small, untill 0,20mm

Comments deleted.

Hi just found this and really want to make it but im having this problem? what am I doing wrong?


Hope the link works as screen shot

first off all you have to rotate 45° the z axis. in this way the piece fit into the bed and the internal infill will be make not inclined.
Second this part is 160mm height. The printer have to manage this limit. Many other user with this kind of problem cut the parts expecially for the rear part that is too high.
I hope to see your GASB One

How did they perform this cuts? i am facing same problem

Thanks, BTW

hi, you can use netfabb basic to cut the parts

Thanks for the reply. my CTC printer only has build volume of 225 145 155mm 5 mm short that's why it wont fit. will try it on my ultimaker

Hi Carletto,

Very cool project you've created, congratulations! I was just wondering, what flight time you get with your 450 mah setup?

around 5-6 minutes. The current consumption is propeller dependent, With 5x3 is longer but the flying wing flight very slow. Currently I use 6x4 but I haven't test the consumption

what happen to my printer ,do you guys fit parts? I need to built bigger printer since

other guys with comercial printer had your same issue. They have solved cutting the rear in two parts. I've not this problem, because the open source Prusa i3, has 200x200x200 work area

How well does this take a hit?

Sorry, You meen about the robustness?
I crashed many time. Some time I've demaged the wings but nothing that is not possible to fix with cyanoacrylic glue :)

Great! Yeah I don't want to go through a full 3d printed airframe in one crash xD


I am printing this at the moment. It seems the rear part has a height of 226mm ? Do i need to split it? Or did you print that laying on its side using supports?

Thanks in advance,

The rear is 160mm large x 190mm height. Please check that the cube reserved by the slice could be more bigger of real need. I don't know how fix this.

thank you for your answer!

My Simplify 3d says, the rear is 226mm in height. but it doesnt matter anyway - my Wanhao i3 can only print 180mm high - so i just splitted the rear apart and print it in 2 pieces. Thanks!

PS: the project is really great - also love your instructions about printer settings and infill alignment - that makes things much easier! after my GASB has had it´s maiden flight we are gonna print a whole ARMY of these. (We have about 10 wanhao i3 spread across our flight club members so production should be quite fast! ;)

I really appreciated that you like my GASB. Just a suggestion, yesterday I added a note in my page. The following:
Please pay attention, in order of flight, you have to keep the exit border of the ailerons, 3 mm upper the exit border of the wings. Thats all for a good flight.
I'm waiting your pictures and video too :)
Ciao Carlo


Hey, thanks for sharing!
Working on it right now, printed the first part of the fuselage and looks good so far! Can't wait to fly it :)
Will post images when it's done.

Regards and thanks again!

Where did you get the parts for it?

Normally I buy the parts on AliExpress from china. Is very cheapper but require many time :(

Is a very pleasure for me. I hope to see your work and I'm waiting your comment about flight characteristics.

Please pay attention, in order of flight, you have to keep the exit border of the ailerons, 3 mm upper the exit border of the wings. Thats all for a good flight.

I stay tuned

I started the printing, not finished yet, neet to carefullly check dimension of my printbed - as you see in the MAKE session's photos there is a missing part on the orange part of the wing due to wrong alignment on the bed.
It nevertheless print beatifully if you follow the instructions.
I would only suggest to fit a more universal motor mount for different size motors

thansk for sharing, this is a huge amount of modeling work!

Yesterday Nino, the president of my air field, flew the GASB One launched by a catapult.
See the result here: https://youtu.be/1L2V8Cq05J4
Seems amazing!

hi, this looks like a really good design and i went through your BOM and i am unable to source Aileron, can we substitute it with a 3D printed object or any other alternative

I use this http://s.aliexpress.com/MbAJn2uA
but is only for comfort you can avoid this part. This part allow to setting the 0 point of the aileron more quickly. You can use only the steel bar directly in servo arm and aileron, just pay attention because the aileron arm is fragile

Thanks a lot for the link :)

hi, i started sourcing parts for this project, can you please tell me if these this motor and esc combo will work with 2S lipo and will work for this project? http://www.ebay.com/itm/New-XXD-RC-2200KV-Brushless-Motor-A2212-6T-ESC-30A-Brushless-Speed-Controller-/172317174294?hash=item281ee76a16:g:bycAAOSwXeJXc405

The motor in your link is too heavy (50g) and too much power. I use this motor but for other application. In GASB One you need a 20g motor. With a propeller 6x4 runs up to 120Kh so is not suggested use a motor more bigger. The fixation of the motor in your link is different and doesn't fit the model.

I don't have any servos yet. I printed the canopy first and then the rear and front parts it appears slightly too big? I have a horrible feeling that my z axis is not calibrated right. Could you tell me what size in height the front and rear parts should be, if they aren't right then I need to calibrate my z again and start from scratch. Thanks.

retro 189,2mm
front 101mm

Today another good flight. Please see here: https://youtu.be/gBsTy2fPi9c

<3 i want to print this but my printer ctc is to small 230x150x150mm :(

Hi! do you think, it can carry a fpv setup? Mille grazie

Yes. The canopy is easily changeble to fit a camera

Ciao Carlo, prima di tutto complimenti perché hai fatto un lavoro eccezionale. Poi volevo chiederti, dato che con la mia Prusa I4 non riesco a stampare più alto di 18,5cm, potresti dividere la fusoliera in maniera diversa. Per capirsi: invece di 20cm il rear e 10,5cm il front, potresti dividerla 18cm il rear e 12.5cm il forn?

Ciao e grazie

Ciao Paolo,
come puoi vedere alla penultima foto di questo link: http://www.thingiverse.com/make:248630, ho fatto diverse esperienze su dove dividere il corpo centrale, Il problema nel tagliarlo sulle superfici a contatto delle due ali è che il successivo incollaggio con la parte frontale, non viene perfetta (usando la colla ciano, non appena le due parti si toccano non sei più in grado di fare degli aggiustamenti), ed a sua volta l'incollaggio delle ali al corpo non è perfetto con il risultato di un montaggio precario ed esteticamente molto brutto. La soluzione migliore, secondo me e seguendo anche i suggerimenti di altri utenti che hanno il tuo stesso problema è tagliare il file STL alla quota massima da te stampabile. La parte finale del corpo, quella vicino al motore, non ha alcuna funzione "accessoria", puoi tagliarla dei millimetri che ti serve (fino ad arrivare al basamento del motore). L'unico piccolo inconveniente è che di fronte all'elica ci sarebbe una superficie piatta il che può provocare qualche piccola inefficienza e rumore del motore, ma questo è molto comune nei modelli in depron. Inoltre, non fidarti della quota che repetier assegna al pezzo, se noti gli ultimi mm del cubo che riserva al pezzo, sono vuoti! Per pura informazione specifico che questo è dovuto al fatto che per ovviare ad un errore che mi da il mio CAD (?!?), ho dovuto lasciare un filo di un millesimo di millimetro (che lo slicer non considera) nel bordo di uscita dell'ala (che è qualche millimetro, più alto, rispetto al pezzo).
Ciao, aspetto una foto del tuo GASB One e le tue impressioni sull'oggetto e su come vola.

GASB One - RC Flying wing fully printed (ONLY 9 PIECES GLUELESS)

AUGURI for a great job!, I would interested to see a list your full setup?

Ciao DAquad, have you Ser the PDF with the instruction and the printer parameter? This is all I have. If you Need something else specifics pleas let me know. Ciao Carlo

Hi I really like the look of this, i want to make this. Where do you get the 1mm compliance aileron rod fittings from? Thanks Mark.

Ciao Mark,
normally I buy the steel rods in my modelism shop. It is commun in the modelism shop find a section with carbon rods and steel rods. If you need the 4 small pieces of 20mm, I would like inform you that Yesterday a friend of mine, show me that for this scope, he used 4 pins of a diode (or resistence something like this) and this solution works properly.
Please, as soon you have printed the flying wing it is very appreciated to me if you send a picture with Thingiverse "make" function :)

Ciao Carlo, I already have the steel rods but don't know where to get those plastic attachments again probably a modelling shop somewhere would have some, or I design and 3D print some! Would you be willing to release the cad files so that I could modify the design I am looking to add fpv to it! Thanks, Mark.

Yes the plastic part that connect the aileron with the steel rod is a commercial part that you can found in a modelism shop. If you are already involved in modelism you must have this part or you can ask to a your friend. I buy this in Aliexpress 1€ for 10 pieces more or less. Before to distribute the DWG I prefere to have a feedback from the user.

I would like to buy the plastic part for the aileron connect from aliexpress could you give me a link Carlo please?

Ciao Carlo, that's just what I wanted would never have found them. Printed out the canopy was the correct weight and 2 ailerons yesterday, measured the ailerons at 9g each at 0.32.... Waiting for more PLA for the bigger prints. Have you got a guide to wiring as I am new to plane wings, I have a receiver FS-i6 for my turnigy spare I don't know which aileron to connect where to get the correct turn on the craft. I notice you don't use a flight controller in this thing if they are not needed then that's great! Mark.

This kind of informations are missed since is not the model for beginner. Usually to start to flight they take a glider bigger and slow. I've some doubt that a beginner can start from a flying wing. My suggestion is mount all, and give the model an expert to test it. Anyway, you need an ESC 20A to drive the motor, this have to be provided to BEC to feed the receiver (find on aliexpress ESC with BEC), 2 servos 3,7g, and a receiver.Ch1 first aileron servo, Ch2 second aileron servo and Ch3 ESC. The flight controller is not needed. My suggestion is ask to a forum on your country how wiring the GASB One, I hope that is better to my english :(

The information and your English I understand very well thankyou, I will take notes, I have a 25A esc already and just needed the connection notes, is aileron Ch1 the left one and aileron Ch2 the right? I have flown quadcopters before so may be Halle to handle the wing! Thankyou Carlo. The forum suggestion I shall also check out.

For Ch1 or Ch2 left or right is indifferent because is managed by the radio. If you have a radio programmable you have to use elevon function that mix the left right up and down command properly to manage the aileron on flying wing. If you don't have a programmable radio, instead, you have to use an external mixer for elevon management.

P.s. Of course I will send a picture of my build when it is done!

Also today a very nice session of Flight with my GASB One. Flight very stable and beautifull landings. Let me knw your esperienze with GASB One.


Ciao Carletto73,
cosa a usato per incolare il PLA ?
LOCTITE 454 o altre ?

grazie et scusa per il mio Italiano scrito.

Bonjour Carletto73,
quelle colle a tu utilisé pour le PLA ?
LOCTOTE 454 ou autre colle ?

merci et désolé pour mon Italien écrit.

I've used cyanoacrylicate glue that normally is used in modelism.
If you download the manual you can see the reference

LOCTITE 454 e buona per questo lavoro.


la LOCTITE 454 est la bonne colle pour ce travail.


Thanks for the neat design. Looking forward to trying it out.
Can you please make better videos? The vertical orientation of the camera (phone?) make it very difficult to see what is going on. Perhaps have a friend shoot with a real video camera which can zoom in on the plane as it flies.

I will do as soon as possibly :)
I was few minutes ago in my aero field area, I made 4 fly very very good. This version 5 seams very stable. I took some videos in landscape, I try to mount something and I will post

Hi Carletto73,
it`s not possible to print your stl files with an xyzprintig 3D printer, because it is to high.
Maybe you can correct the files or send me the Autocad files? :)

try rotating the ones that it says it cant print, to a 45 degrees.

What are the maximum dimensions of your printer? I will share the autocad after the first feedback. In this moment I prefere don't share it yet. Normally is better share the drawing when the design is validated from many people and the first improvements are put it place. Ciao Carlo

The Dimension is 200/200/200.
Especially the rear.stl is too high... maybe you can fix it?

Also the prusa i3 is 200x200x200 and this design is compliance to this dimension. The stl "cube" reserved for some parts maybe exceed to 200mm but if you check better you can see that the real part is more small. For example repetier tell me that the dimension is too big and ask me if I want stop the slicing. I answer no and the slicing ends correctly.

Hmm Try to print it with Simplify3D but i cant get the weight what is show in the PDF. I try diffrent settings. Did someone try to print it with S3D?
I hope someone can help me.

It depends on a few factors. I printed the parts with a .5 nozzel but all the other settings gs and mine came out to 440g

Can be useful if I post my Gcode files? I'm not sure if the Gcode for my Prusa works with other printer

I forgot to tell you that I use repetier and Cura

For better handling you could move the control surfaces more outward to the end of the wings. This gives them a bigger distance from the CG for better pitch control and further from the longitudinal axis for a higher roll efficiency. Nice idea though. I really want to try this. Is 0,3mm PLA not too brittle?

You are right but at the moment I prefere to keep the flaps in this position to simplify the design. The servos mus be more upward as possible to achieve a good CG solution. Maybe the better solution is to have a flap long ad the complete wing but I have to do some test about how fix the two pieces. With 0,32 PLA is just little brittle but I prefere keep low the weight because I am sure that it fly.

Should mention to mirror the right side of the model.

You are right. The three right parts must be printed using the left models stl and apply mirror function

Unfortunately I was more worried about fitting them for a one plate print. Didn't realise it untill after it was done printing lol.

V5 showes over 700 grams at 100% scale and 3% infill...

Impossible! The total weight of version 5 printed with 0,32mm thickness and 3% infill is 256g included canopy. You can check also the partial weight in the pictures and the mm of material for each piece in the pdf manual

Wow, I'll re-slice when I get home. But that's what the slicer states with 2 shell, 3% infill. I will update when I try again.

With Cura you have to set only one shell of 0,32mm thickness. I have a nozzle of 0,35 in my printer prusa but I discovered that is possible to create solid with a shell more thickness

With cura set at .32 shell, .2 height, 3% infill, flow at .98% it shows 341 grams. 42 meters.

Then i make a miracle :) No probably there are ather variabilities. In this moment I can't check because I'm in vacation. I think that with 340g it can fly but is better print in 250g

Hi Carlo,
you really made a miracle :-)
With 0,32 Shell, 0,2 Layer Height and 3% Infill, my one has also 347 Gramm.....
Maybe you found a Special-Lightweight PLA ? ;-)

I´m still waiting for Motor, Prop, Servo and ESC.

Best Regards from Shanghai !

In cura I had it set to 1mm thickness which is 2 shells for my .5 nozzel. Going to print all the peices at once tonight. With one she'll I'm down to 436g which is much better.

I started to print with 0.4 extruder, and the rear became 124gramm the internal wing 101g. I decided to quit this project cause it was possible to have a 6-700+ flying weight.
Then i reprint some parts with 0.3mm extruder the rear part now 96g, the inner wing 58g external wing 40.5g so i think this way there is no miracle just follow the directions of "pdf"

Very cool! It looks a lot like the Hortan 229. Did you build this just for leisure or another reason?

The RC models are my passion for this reason i have build this model. I hope that other guys build this model and give me feedback.

i see a launcher on the ground. did you ever get to use it on this plane? i saw you hand launched it in the first video but then we don't get to see the other take off's. great looking plane

Sorry I'm not a good cameramen. In the begin I crashed 4 times before find the correct CG. At the end I've flew a couple of time with my first sample white of version 4. Unfortunately I've only one battery. Now I printed the version 5 with some improvements but i not fly yet. As soon I can I will post the video. I hope to remember to made it in landscape ☺

ciao carletto73, bel tuttala! ti faccio solo un paio di critiche se permetti: innanzitutto perché ha messo gli alettoni così interni? se li metti sull'esterno dell'ala lavora molto meglio, serve meno deflessione della parte mobile e il servo è sollecitato meno. altra cosa, ma forse è la foto che inganna, meglio dare più segmenti alla curva per avere un profilo più lineare
ultima cosa, l'infill in quel modo non serve quasi a nulla. ti consiglio di prendere spunto dall'interno dell'ala dei modelli di 3dlabprint, guadagneresti in peso e robustezza

sicuramente appena trovo il tempo lo metto in stampa per stupire la gente al campo volo!!

Ciao Dea90 e grazie dei commenti. Per gli alettoni ho già ricevuto alcune critiche al campo volo. Diciamo che sono in quella posizione per poter mettere i servo più avanzati possibile per fare in modo che il CG sia rispettato senza mettere piombi. Sono lunghi 160mm, potrei arrivare a 200mm con la mia stampante cmq i primi voli non sono stati malaccio. Diciamo che con gli alettoni in quella posizione è leggermente sordo ai comandi ma non più di avere un esponenziale un po' altino. Altro problema a portarlo fuori è che l'ala si restringe molto e diviene piu difficile garantire robustezza. Per il profilo ti garantisco che è abbastanza curvo le foto non rendono anche perché si vede l'infill in trasparenza. Il parametro FACETRES è settato a 10 le spigolature che rimangono sono dovute alla risoluzione di cura, del fw della stampante e dai sui limiti hw. Per l'infill passando dal 2% al 3 l'ala è diventata molto più robusta. Prima era difficoltoso il lancio a mano senza danneggiare l'ala nel punto dove la si stringeva con la mano. Sto pensando anche di ristampare al 2% ma aggiungendo una pinna per poter prendere il modello da sotto durante il lancio, proteggerebbe inoltre anche l'elica all'atterraggio. Cmq darò un occhiata ai modelli che mi ha detto, si può sempre migliorare☺
Se lo stampi fai la versione 5 che è l'ultima. La sua forma è spettacolare con la canopy.
Ciao Carlo

per gli alettoni allora prova a farli a tutta apertura in due pezzi a incastro , risolveresti il problema della manovrabilità e non comprometti il cg!
come motore ci starebbe un 2204? così si potrebbe usare una 5x4,5 o meglio ancora una 6x4 facendolo diventare un bel missile

Per il motore ho previsto due fori passo 16mm
Per l'elica una 6 pollici si può montare
Per il motore ti garantisco che basta un morotino da drone BE1806. Nel video ero a metà gas
Per gli alettoni per il momento penso di tenerli così. Al momento vola bene e mantengo il progetto semplice e fruibile da più gente possibile

Ovviamente non è il miglior tuttala di sempre. I modelli in EPP pesano un quinto di questo ed ho visto video di crash contro muri a gas aperto senza che il modello si graffiasse. Questo se atterrà un po allegro rischia di danneggiarsi. Lo scopo era di fare un modello stampa e vola, della serie: "Peccato ho rotto l'ultimo modello! Aspetta che ne stampo uno e domani volo con uno nuovo!"
Inoltre, altro scopo era sperimentare qualcosa di nuovo che, almeno io, in Italia non avevo mai visto. E' molto frequente vedere telai di droni stampati ma aerei ad ala fissa un po' meno per via delle difficoltà costruttive a mantenere i pesi bassi. Con questo progetto, si riesce a portare al campo un modello stampato molto semplicemente.
Aspetto i commenti di chi vorrà provarlo e di vedere qualche recensione del modello all'opera :)

Looks great, will try to build this plane. Can you please publish the files as step or iges? I want to modify it for fpv usage...


Please check PM

Could you also give me one?

What is the scope? Before modify please test my version and let me know your comments

bel lavoro Carletto, penso stampare il tuo modelo quest'iverno.
scusa per il mio Italiano scritto.

je suis Français .

Ciao a tutti,
oggi il modello ha volato ed anche bene con condizioni meteo proibitive almeno per un collaudo.
Nei primi quattro tentativi di decollo il modello è caduto al lancio. Una volta trovato il centro di gravità corretto invece il decollo non è stato più un problema.
Nella prima caduta il modello ha picchiato forte di punta e si è spezzato in due all'altezza di un servo sulle ali. E' stata eseguita una rapida riparazione al campo con ciano e fasciatura con nastro rinforzato. il modello così riparato ha subito altre tre cadute al lancio ed ha poi fatto due voli regolari.
Con la batteria 3 celle 450mAh ed elica 5x3 ha volato per 4 minuti e la batterua non era ancora scarica.
Il modello è veloce ma anche un buon planatore. Occorre apportare due modifiche. La prima è quella di fare il vano batterie ed elettronica più avanti rispetto ad oggi di 3 centimetri per avere il centro di gravità a 145mm dietro l'incrocio del bordo di entrata delle ali. la seconda modifica è quella di costruire sotto la pancia una pinna irrobustita per lanciarlo da quella posizione anzichè dalli ali, questo perchè le ali essendo così sottili sono anche fragili e tendono a rompersi se durante il lancio si stringe troppo con la mano. Aggiungerò anche la canopy ed i riferimenti per il centro di gravità.
Il peso finale è di 334 grammi.

Sotto trovate il link al video con il decollo

Super !!!
Elle vole magnifiquement bien. Super projet mené à son terme. Félicitations.

and also take in account that the test was come with strong Wind

Avec quel logiciel l avez vous dessiné ?
J ai hâte de le voir voler

I've used Autocad. Me too would like to see fly my model but I havent the motor yet :( (also time)
In any case the weight is just 213g so have to fly certainly. Please someone to try it and give me feedback.

grazie Carletto73,

tu avait quoi comme hélice pour les premiers test, et le moteur combien de KV ?

No yet. I hope to have the motor and the time this weekend. About the motor I would like to test the DYS BE1806-2300kv that thrust 400g with a 3 cells

Good job! Can you tell me the weight without servo? Which nozzle do you use?! Thanks!

Ciao samu,
the weight without servo is 213g (with CA glue and 4 pieces of steel rods 20mm)
I use a nozzle 0,35mm

For every piece except the nose I print with top and bottom thickness 0.6mm, the external thickness 0.3mm (I learned that the printer can prints thinner that the nozzle) and the internal is 2%. The nose must be robust (external thickness 0.5mm internal 5%)

This scale is the maximum to be printed with a PrusaI3. In the next step after the fly test, I would like remove the cuts on the wings with the form of the servos 3,5g and put a square cut to allow tu put any kind of servo (also bigger)

Ciao, molto bella la versione 4! Volevo procedere alla stampa ma ho un paio di domande, che diametro di nozzle hai?!
Rinnovo l'invito a un confronto via mail: samuele.carpi@gmail.com
Intanto complimenti!

Ciao Samuele,
il nozzle che uso è da 0,35mm.

Purtroppo non dispongo di un motore BE1806-2300 (della DYS ma lo fanno anche altri) e non riesco a provarlo questo fine settimana. Questo motore dovrebbe spingere con una tre celle più di 400g il tuttala i ODV ne pesa 300. Se stampi e lo provi mi fai un piacere per supportare lo sviluppo. Ti do solo un consiglio. Il mio slicer (cura non aggiornatissimo) pone l'infill dove vuole lui. Una volta che hai fatto lo slicer, prima di salvare, prova a guardare dove ha posto le linee di riempimento e nel caso cambia la posizione del pezzo sul piatto e disponilo in modo che queste cadano nel punto migliore. Nelle ali evita un rinforzo parallelo all'ala per tenere il pezzo leggero (solo rinzorzi ortogonali al corpo del tuttala). Se ci sono strutture tipo i fori per i perni degli alettoni, fai in modo che gli infill cadano su queste strutture in modo da irrobustirle.

Con uno spessore così basso ho trovato un beneficio a stampare 10 gradi più alto del solito perché ho notato che la superficie di 3 decimi viene meglio

Ciao, mi interessa molto il tuo progetto, stavo lavorando anche io a qualcosa di simile, costruito in modo un po' diverso, e ho qualche idea secondo me interessante, se ti va possiamo confrontarci. Ti lascio la mia mail samuele.carpi@gmail.com

Today I have flight. The model seams too much duty and the motor used has not sufficient power to take off. In the next days i will put on place many changes. The wing span pass from 60 to 80cm. The motor pass fron 19 to 29g. As soon as possible I will try the new one. Stay stuned!

comme Peluche44270, photo et vidéo s'il y à serait bien cool.



The same,
I will do this saturday.
I will let you know

merci, c'est super!

L avez vous deja fait voler ?
Avez vous des photos ou des vidéos ?

I will do this saturday.
