Fantrainer

The RFB Fantrainer (or Fan Trainer) is a two-seat flight training aircraft which uses a mid-mounted ducted fan propulsion system. Developed and manufactured by German aircraft company Rhein-Flugzeugbau GmbH (RFB), it has been used by the Royal Thai Air Force. Development of the Fantrainer commenced during the 1970s. In Germany, it was selected as the winner of a competition for the Luftwaffe's Basic Trainer Requirement, having beaten both the Pilatus PC-7 and Beechcraft Mentor. However, no orders were forthcoming from Germany as it had committed to buying American fighters (F4 Phantom and F-104 Starfighter) which included a deal for pilot training in the United States. At one point, German flag carrier Lufthansa also reportedly took an interest in the aircraft, noting its jet-like handling. Pilots have confirmed the type to be relatively fuel-efficient and capable of providing a true "jet feel" for a reasonable price. The Royal Thai Air Force operates the FT400 and FT600 versions, using it to train ab initio pilots who then went on to fly the Northrop F-5E fighter aircraft.
