Reported in 1964, the Frazer-Walker Gyrojet four-place VTOL amphibian to be built by Handley Page Ltd, London, sold in the US by Frazer-Walker Aircraft Corp, New York, has a 250hp Lycoming engine mounted aft driving a two-bladed pusher propeller. Lift is from a three-blade rotor fitted with mechanical “spin-up” device for short takeoff and a tip-jet powered syatem for use when a vertical takeoff is desired. The fuselage is of fibreglass. Royor blades are uncoupled from the engine in flight and rotate under aerodynamic forces.
