Fk11 1997 / Otto Funk
The most unusual concept masterminded by O. Funk has been by far the FK 11 project. An automobile engine was used for the integrated middle motor to drive two propellers mounted on the sides of the fuselage.
This airplane was intended to optimize the efficiency of propeller aircraft, as it made it possible to achieve astonishing flight performance with even the lowest engine power.
June1997 saw the maiden flight of the FK 11 prototype which has since then been continuously developed, optimized and tested. Serial production has been considered, but not started.
