RE: Foam wing Lay Up
I don't have the skill at this point either, but watching this video sure made it look easy. I would think you could put some sort of spar in a white foam wing, and still keep the weight in tact while not compromising the strength.
I really think this could speed up the process of making a q500 wing, without expensive cnc cut molds if we borrowed some of this glider technology.
I'm not even thinking about q40 wings at this point, but quickee wings gotta be doable this way.
