History

Otto Funk and his son Peter designed the Fk9, which first flew in early 1989 and made its public debut at the Aero fair in Friedrichshafen that April. B&F Technik was set up in 1990 to produce it. It developed from a mixed-structure, fabric-covered aircraft into a wholly composite machine.

Variants

The Marks 1 and 2 had fabric-covered wings and a steel tube fuselage; later marks use a glass fibre fuselage and carbon composite wings. Engines have included the Rotax 447, 503, 912 UL and 912 ULS and the Ecofly M160, and a tailwheel undercarriage is an option.

Where you'll see it

At least 370 Fk9s had been sold by late 2008, flying on four continents. The type is an accepted FAA special light-sport aircraft and remains in production in Poland and Germany.
