Printed it as a mini Trimaran 30cm with Radio Control from an RC Heli

It's quite strange, I've tried to print the boat but the three parts of the central hull don't correspond. Did anyone had the same problem?

hello
can you give me the profile that you used for the two foils?

Did you ever finish it?

I would like to see the maiden voyage.

I'd recommend using Monocote for the sail skin. It's the same thing we use to cover RC airplanes. It irons on then heat shrinks to get rid of the wrinkles.

You would need to be very careful applying heat. I think MonoKote shrinks at around 150 Celcius (300 Fahrenheit), which as we all know, is close to the melting point of PLA. I haven't tried it but as the film shinks it could cause your sail sectins to distort.

Depends on how tight you shrink it. You can actually shrink monocote with a hair dryer so it can be done at lower temperatures...it just works better with a heat gun.

Still waiting to hear about the sail... thanks

Is the sail ready yet?

keep up the good job!

wow amazing work of art! you have outdone yourself. i have always been interested in sailing iv'e never been on one. so i wanted to get a r/c model for years. this is it when it is fully done id like to print one to have for myself. i look forward to your progress! keep on keeping on.
great job!

Awesome! Amazing effort. I was just cruising google photos for BOR build photos and I saw this. I was a part of the team that actually built the Beast90 (just a boat builder,not an engineer or designer). I am glad to see that it has inspired you to create. Have fun with this! I look forward to seeing a finished version. FYI...the wing is going to create a huge amount of lift. If your intention is to create a functional RC then some rigging (and a way to spill some wind) is probably needed. There will be a lot of dynamic force at the base.

Hey, thanks so much for stopping by and commenting. I'm extremely interested in the build process and such that went into the actual boat compared to my model. Maybe we could talk about it some time, if you don't mind.

I'm not quite done designing the wing, but the rear element will be separated into 3 segments, with the top 2 segments camber compared to the bottom, control segment, being controlled via a delta method and a movable rod (I'll just use some 1.75mm abs filament). The wing will also be supported via rigging to the nubs visible on the outriggers as well as the nubs on the front of the main hull. And since I'm using asymmetrical foils, I plan to use winch servos to raise and lower the windward foils on tacks and jibes.

Awesome design skills and great job putting it all together! The amount of effort put into this seems amazing, will be looking forward to future works. :) Best luck with the competition!

For anyone interested: am in the process of test printing parts. Accidentally cracked the main middle hull when removing supports :( . Might need to add some ribbing to the larger main hull sections. Have completed and will upload revised outrigger hulls including foils. Also working on wingsail.

When are u gonna make a update. keep up the good work
