Thanks for this awesome design ! Do you think I can scale it to match a 3" drone ? Thanks !

There seems to be some design bug on the rear arms, on top, right behind the motors. The small "roof" is above the arm creating a gap underneath. Is that on purpose?

Awesome design, only caveat is the battery and top cover are being held in place by a rubber band. In a crash or just high g forces will RIP the top cover off. Someone should do a version that bolts the top cover down.

Hi, where you do wire the 4 in 1 esc on the f4? the main lipo pads or on a single motor power pad?

Very nice and simple design, Super clean, Really like it

Thanks for the feedback! Much appreciated.

Great design. Which propellers did you use?
And where did you put the LitteBee?

Hi, thanks for your comment. The propellers are Team RaceKraft 4040 Quadblade in clear as seen here: http://www.readytoflyquads.com/team-racekraft-5040-quadblade-race-prop-clear-951

The Littlebee is mounted as part of the main stack, on the very bottom. Conveniently it uses the same mounting pattern as the FC, then I just made a custom bracket to mount the VTx, also using the same mounting hole pattern.

Hope that answers your questions!

This looks awesome. I think you should revise it (I can try, but I am not very skilled at 3D design) to be a mini version of the DRL Racer 3 quad....

Thanks for your interest and your comment. I have no plans to develop or modify this design at all as I've since moved on with other unrelated projects. Cheers, Zack.

Do you have any videos of you flying it?

Yes I do! I'm a terrible pilot though, much more interested in the design/building part of the process. You can see more videos on my YouTube channel: https://www.youtube.com/HXLMES

Is there any list of parts that are needed to assemble this thing if so can I get a list of them? For example what boards or motors are best for building it

Yea mate, scroll to the bottom of the page and check the section 'Electronics Used in This Build'

Are 2300KV motors fine for this guy?

Absolutely mate!

Have you already tried a version with 5" props yet? Just wondering as that's what I usually use. Interested to hear if weight is the issue, or if 4" is just your preference here.


Just made the 5IN version

Hey Tact2,

I have no plans to modify this frame for 5" props, however the first frame I designed uses them: https://www.thingiverse.com/thing:1788127

I definitely prefer the smaller footprint of this frame with 4" props for portability!

Kind regards,

HXLMESFlight Prototype V1

It would be awesome if you could modify this to fit 5" props. I recently just broke my 5" frame and I am looking for one that I can 3D print. I really like the style of this frame and I want to test it out. All I have is 5" gear though.

I just made the 5IN version

Hey CarterJardine, thanks for the feedback. As I said above, I have no plans to modify this frame further. Perhaps you could simply put 4" props on it? That would be the only expense as you can still use the rest of your current running gear as is, and props are only about $3 for a set (if that)

Alright, my quad is specifically built to run 5" props but maybe I can edit your model? what design software did you use? also you can disregard the email I sent earlier

I appreciate the enthusiasm, so be my guest. I used Fusion 360, feel free to remix this design.

Do you have the original fusion 360 files? I want to make a version that bolts together?

Got it, thanks for the quick reply!
