Cool idea for a helicopter. Seems the 1950's was crazy for helicopters!

Hello, I'm studding helicopter aerodynamics and i 'll like discover how works coaxial helicopter .I’m looking for co-axial main rotor head details and drawings. I would really appreciate to get a sample of this ultra-light plans.I think he could be more stable if he was more compact.

Hi my name is Joe Bucci I have a set of plans for the little zipster. A` friend of mine is a aircraft builder (one of the best) i think he said it is not real stable this friend of mine knew Bensen he was one of the first ones in P.R.A when they started it. Send me a E-mail i will tell you where to get the plans and i will have Frank contact you,(if you wish) Frank builds mostly rotorcraft he will make parts for fixswing also he is excellent with rotorcraft, Thanks again Joe Bucci
