The Akaflieg Stuttgart FS-16 Wippsterz was a glider aircraft that was designed and built in Germany from 1936. Only one example of the design was constructed.

Development[edit]

Akaflieg Stuttgart wanted to build a glider with reasonable performance that was safe and simple to fly, the result was the FS-16. The design employed a cantilever wing attached to the top of the fuselage; the rear portion of the fuselage was raised, similar to the Akaflieg Stuttgart F.1. The FS-16 as constructed had no vertical tail, but used pivoting panels on the wingtips for roll and yaw control. It had no tail-skid, using a single large skid under the front fuselage with a spur extending rearwards for support and stability on the ground. Flight characteristics with the rotating wing-tip panels were not as expected so a conventional vertical fin on an extended rear fuselage, and ailerons constructed from fabric-covered Duralumin on the outer wing traling edges, were added after initial flights.
