This is a design for rcexplorer's tricopter v2.5 http://rcexplorer.se/projects/2011/09/the-tricopter-v2-5/


The two STL files are for the top and bottom of the body of the tricopter. I used 10mm square armatures and bolted the frame together with M3 hex screws and lock nuts. Friction keeps the arms in place which means if you have a crash they have some movement and tend not to snap.

I've used velcro on the top plate to attach my control board, and receiver. My lipo is mounted underneath with a scorpion strap and slots nicely between the bolts. The hole on the bottom is purely to reduce weight (if you're using the scad file then comment out the indicated line to eliminate the hole and print the top).

Hi, I was wondering, did some one try to make this with 12.7mm wooden booms?

Does anyone have a suggestion on an alternative thing that works with 12.7 or can convert this one?


Hi thank you so much for posting this. It saved me a lot of time. Is this super strong or is it kind of brittle. I have never flown a tricopter and intend to crash so durability is key. I also should mention that I want to make it out of pla. Thanks again!!!!!

I've not had any problems. When I crash, repeatedly, the damage is to the spars (that's why they're wood). I think you'd have to do something special to break the centre plate.

What is the thickness of the top and bottom plates without the stand-offs?

Should be 3mm. This can be changed in the SCAD file.

How well does it hold up to vibrations, etc? I'm wondering if I should attempt this or if fiberglass would be better.

I've not had any problems with it - though the vibrations will depend heavily on your motors and how balanced your copter is. Certainly the number of crashes I've had which were hard enough to snap the armatures are into double digits and the body has never suffered.
