A single place helicopter comprising a lower airframe and an upper airframe, having a rotor shaft attached thereto, rotor blades, and a hub on said rotor shaft with means to change blade pitch for vertical flight. The upper airframe comprising a rotor system, engine, tail boom and tail rotor tilt as one unit with the pilot forward, rearward and in a lateral attitude for directional flight control by means of a hinged gimbal joint or block fastened between the two airframes. By allowing the pilot to move with the rotor system this configuration combines physical human interface and mechanical airframe manipulation to change the plane of rotation controlling the thrust vector and flight direction of the aircraft. |
