Scheibe Bergfalke II 55 Model Glider by Jilles Smits

This iconic rc glider has been modelled by many designers, but none have caught this sailplane in the way Jilles Smits has. The model is easy to build and has really good flying charateristics. A build thread can be found on the Scale Soaring UK website.

Scheibe Bergfalke II 55 Glider

The Scheibe Bergfalke (German: “mountain hawk”)

is a German glider designed by Egon Scheibe as a post-World War II development of the Akaflieg München Mü13 produced before and during the war.

Design and development

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. It was a mid-wing sailplane of conventional design with a non-retractable monowheel undercarriage and a tailskid. 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.
