AISA GN

The AISA GN was a prototype four-seat autogyro developed in Spain between 1971 and 1982. it featured an extensively-glazed cabin fitted with a pusher engine and tricycle undercarriage. A separate tail fin was carried at the end of two booms mounted to stub wings. The prototype was developed with a 200 hp engine.^[1] The aircraft suffered from an extremely prolonged development, but finally took to the air on 20 July 1982. Shortly thereafter, however, it was damaged and finally abandoned.
