Tandem rotor machine powered by a 100hp Franklin engine. It had a neat fuselage of steel tube covered with aluminium and fabric, with a tricycle undercarriage and a forward cockpit for two occupants seated in tandem. The rear pylon allowed the rear rotor to turn on a higher plane than the forward rotor so that the arcs could overlap safely.

I have been envisioning an upgraded version using two blade rotors sychromeshing (so you don't have to worry about overlap) and powered by the now well-known Solar t-62 gas turboshaft engine. A one man version would actually be able to meet the weight restrictions for recreational non-licence.
Rotor Diameter: 5.46m
Empty Weight: 354Kg
Max. Takeoff Weight: 544Kg
Rotor Speed: 500 1/min
Max. Speed: 160Km/h
Cruise Speed: 127Km/h
Service ceiling: 4,207m
Price (1946) 12,000$

I flew the MC-4 1958 for Gish Jovanovich at Santa Monica CA. I don't have possession of any technical info, but if you have any questions I would be happy to try to answer them.
