The Scheibe Bergfalke IV is a two-seater glider in composite construction for training and performance flight from the manufacturer Scheibe-Flugzeugbau in Dachau .


The Bergfalke IV represented the last development stage of the Bergfalken series, in which emphasis was placed on improved performance in high-speed flight.


The fuselage consists of a tubular steel frame welded in a half-timbered construction . The seats are at the same height one behind the other and have a large, one-piece blown, laterally hinged hood, which is also used on the SF 28 motor glider . The nose of the fuselage is clad with GRP and is a bit more pointed than its predecessor. The rear part of the fuselage has a semicircular GRP cladding at the top. A rigid, unsprung central wheel serves as the chassis. A runner is no longer available.

The wing structure is designed as a single spar and divided for easy installation. The profile is a modified Wortmann laminar profile. In contrast to the previous models, the wing is not swept and designed as a double trapezoid. In contrast to the Bergfalken III, the wingspan has been increased slightly. Schempp-Hirth airbrakes that extend on both sides serve as landing aids. The tail is shaped like the previous models as a self-supporting timber construction. The fins are covered with plywood and the oars with fabric. The rudder is firmly attached to the fuselage; the horizontal stabilizer is placed on the fuselage from above.
