My RC synchrogyro design.
Engine: Enya 40 prop 11x5
Weight: 1900 grs (67 ozs)
Rotor (s) diameter: 130 cm (51,2 ")
RC controls: rudder, elevator & throttle.
The synchro gears were made by a friend of a RC club in Murcia (team ARCM)
It was my friend Georges Chaulet (France) who first designed, built and flew RC autogyros with synchronized rotors. He called them 'Synchrogyres'.
