The Gyrodyne was a private venture development by Fairey to investigate potential designs for high speed rotorcraft. The initial prototype used a conventional, transmission drive with anti-torque provuded by a forward thrusting propeller mounted on the starboard side. The second version used tip jets as the main rotor drive with dual propellers mounted on stub wings to provide thrust compounding.
