The Rhönadler was designed for Schleicher by Hans Jacobs and first flew in 1932. It became the first series-built high-performance glider in the world. Schleicher built 65 in total and an unknown number were built by gliding clubs and individuals. The last one built is the one shown here, built by Klaus Heyn from 1983 to 1986. It went to the Deutsches Segelflugmuseum at Wasserkuppe painted to commemorate D-GÜNTHER GROENHOFF from the 1930s.
