The Fournier RF-9 is a two-seat motorglider of conventional sailplane configuration. Originally produced in France , manufacturing was later taken over by ABS Aircraft in Switzerland , and then by Gomolzig in Germany . The pilot and passenger are accommodated side-by-side, and the aircraft's wings are foldable for ease of storage. It first flew in 1977. The licence-built example was known as the Fournier RF-9 ABS but only one, registration D-KHGO (w/nr.9021) was ever constructed. In 1994, ABS Aircraft GmbH left the development of ABS RF-9 though two further kits had been built, and were later constructed by the Polish Aircraft company Polavia.
