Problems:
-Collision boy is just a box, it can't have a custom shape
-The materials must not end with a number
And, flying vehicles don't need wheels. But since you added hubs, I left them on.

Oh, Didn't know collisions had to be a box
Dont end with numbers? How about gray25-75? Some default textures?
And about the wheels, I though i should just use invisible wheel models :3
I'll check your fixed version out.
