The Borgward-Focke BFK-1 Kolibri, (Hummingbird) was a German three-seated utility helicopter built by Borgward, designed by Professor Heinrich Focke, the co-founder of Focke-Wulf, and was the first German helicopter after World War II. The helicopter first flew on 8 July 1958 in Bremen, piloted by Flugkapitän Ewald Rohlfs, who, on 26 June 1936, made the world's first flight of a helicopter, the Focke-Wulf Fw 61
Design and development Two prototypes were built; they had steel tubing fuselages, covered with metal and fabric and v-tails with tail rotors at their tips. The plywood covered main rotors had three blades with steel tubing spars. The helicopter had a six-cylinder air-cooled Lycoming Engines VO-435-A1B engine, producing 260 hp. The fuel tank was capable of holding 180L. The helicopter could be used for spraying in agriculture, and could carry up to 300 lbs. Development ended after the two prototypes, as Borgward went bankrupt shortly after in 1961.
