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. R.Simpson "Airlife's Helicopter and Rotorcraft", 1998

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. |

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. |

JK,
I like your thinking. Any progress with this new configuration? Do you know who owns the type certificate for the configuration?
