Thanks for the pics, Dickeybird - they helped a lot on giving ideas onthe control system

Anyway, I wasn't thinking "that" small. Let me explain it a bit...
I thought a good way of letting people start with autogiros would be making them more user-friendly. This means you must make an autogiro that could easily be flown and built by everyone, yet a wingless, real autorrotating machine.

Following this thought, I found the Pîco Cub to be the perfect choice for many reasons: it is easy to transport, it is a slow flying airplane (fewer crashes, more reaction time), it's very cheap, and easy to build.

I planned to design a a pylon the SPAD's style, and then post some plans in case it worked fine, or at least a wood pylon that you could build with a few common tools.

My problem? I have no Pico cubs.... However, I found someone who has, although he has only been once flying in my "club". I think I'll make a foam "Coyote" the same fuselage size as the Pico Cub, and try what happens. The problem is what has already been said, how do you do to design an efficient (fast, simple, easy) method of building blades? I've seen a post regarding the use of coro.... Its a pity it doesn't apply to small machines!
