The PLA moose! Inspired by Mr Burns' Spruce Moose. This is my first rc aircraft design. It is a 1000mm span aerobatic plane, loosely based on geometry from the Yak54. It is a work in progress, but it goes together properly and does fly!

My first prototype is printed with PLA. Assembly should be fairly straightforward for someone with rc aircraft experience. I use 400 grit sandpaper to sand the mating surfaces. Carefully clean with PVC pipe solvent (M.E.K, Methyl ethyl Ketone) and glue together with a good quality CA adhesive.

It has a 16mm carbon spar through the wing and a 3mm carbon brace in the elevator surface. It will need 5x 9gm servos (align ds410's fit perfectly), although I haven't drawn the mount for the rudder servo yet. I was planning on mounting it close to the CG and using pull/pull cables thru the holes behind the canopy. The elevator needs 2 servos, the surfaces are not connected to each other. I was planning on using a 3536 size outrunner, about 800kv with a 4s battery. You'll need some CA hinges to. And a bunch of patience. Its a lot of printing!

The orientation of the STL's are not optimised! I'm sure if you're prepared to take on a task like this one, you'll be prepared to take the time to carefully orient your components to get the best results on your hardware.


UPDATE!

Its a bit heavier than I'd like, I'm going to try and strip some weight out of it for the next print. My first build was 1.6kg flying weight! Wing loading of about 30oz/sqf.

It still flies quite well as long as you keep the speed up. I think I was a bit ambitious expecting aerobatic performance from this one! My biggest problem was that it is rather tail heavy, and I had to put an enormous battery in it to get anywhere near balanced. I used a 3536 1050KV brushless motor and a 3300mah 4s battery.

The next revision will have an assymetric airfoil to try and generate a bit more lift at lower speeds. To help with CG location, I think it might be wise to move the elevator servos forward and connect them to the surfaces with cables or long pushrods.

If you print one, please upload pics. I'd love to see it! Feel free to edit it and re-upload but I would appreciate a mention of my original work.
