In an effort to produce the 'Idealflugzeug' the FVA students designed the FVA-11 which was intended to thermal efficiently, transit between thermals at a reasonable speed with relatively low sink rate, land safely at low airspeed and require no more than three crew members for rigging and de-rigging. By using a thin wing section and high aspect ratio wing as well as flaps the FVA-11 went some way to achieve the goals set. Construction started in February 1938, but deliveries of materials were delayed so the FVA-11 was not ready for the 1938 Rhön contest. Flight testing had started and modifications planned for the aircraft but the FVA-11 was destroyed during World War II
