Gwinn Aircar-1271 The Gwinn Aircar was a single-engined biplane with a cabin for two, designed in the USA as a safe and simple private aircraft. Lacking a rudder, it had several unusual control features as well as an early tricycle undercarriage. Development was abandoned after a crash in 1938. The Gwinn Aircar was the only product of the aircraft manufacturing company set up by Joseph M. Gwinn Jr, who also designed it. He had previously worked with Consolidated Aircraft. The Aircar was intended as a safe, easy to fly aircraft that would neither stall nor spin. It used a simplified control system without a rudder. A fuselage which deepened rapidly behind a small radial engine and ended with a fin integrated into it, together with a tricycle undercarriage with a tall and faired front leg, gave the Aircar an unusual appearance.
