Scheibe Bergfalke

The prototype flew on 5 August 1951 as the Akaflieg München Mü13E Bergfalke I and by the end of the year, Scheibe had established his own works at the Munich-Riem Airport to produce the type as the Bergfalke II.{{cite book |last= Hardy |first= Michael |title=Gliders and Sailplanes of the World |year=1982 |publisher=Ian Allan |location=Shepperton |pages=79–80 }} It was a mid-wing sailplane of conventional design with a non-retractable monowheel undercarriage and a tailskid.{{cite book |last= Taylor |first= John W. R. |title=Jane's All the World's Aircraft 1977–78 |year=1977 |publisher=Jane's Yearbooks |location=London |pages=528 & 594 }} The fuselage was a welded steel structure covered in fabric and enclosed two seats in tandem. The wings had a single wooden spar and were covered in plywood.

Subsequent versions introduced forward sweep to the wings, a more aerodynamic canopy, airbrakes, and a tailwheel in place of the tailskid. By 1982, Scheibe had built over 300 of these aircraft, and Stark Ibérica built a number of the Bergfalke III version under license in Spain. Scheibe also developed a motorglider version as the Bergfalke IVM but this did not enter production.

In 1976, two Bergfalke motorgliders participated in the Sixth German Motor Glider Competition. Later, one of these aircraft set a world 300 km triangle record.{{cite book |last= Coates |first= Andrew |title=Jane's World Sailplanes and Motor Gliders |year=1978 |publisher=MacDonald and Jane's |location=London |pages=67 }}
