Well, we tried it again today. This time, we attempted to control the planes' direction by tilting the "rotor disc". I've come to the conclusion that it is a frivolous experiment and control is impossible, but it was still fun. I guess I'll have to find some other silly way to try new things.
BMatthews, could you elaborate on the brush system? I know what you're saying, but where could I get the stuff I need for this project?
