The B&F Fk9, also marketed as the FK-Lightplanes FK9, is a German-designed single-engine, two-seat ultralight, first flown in 1989. It has been developed from a mixed structure, fabric covered aircraft to a wholly composite machine. It remains in production at factories in Germany and Poland and has sold in large numbers, flying on four continents. Otto Funk had designed and built gliders and motor glider since 1970 but the Fk9 was both his first commercial product and his first aircraft with design input from his son Peter. Peter Funk and Dirk Breitkreuz set up B&F Technik in 1990 to produce it. The early Marks 1 and 2 were wholly constructed in Krosno, Poland; current models are 85% Polish built, with final assembly in Speyer, Germany. The type is quite often referred to as the Funk Fk9, though not by its makers. More information...
