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.
