Designed by Bruno Gumpert as a training aircraft, the fuselage had a grid construction to sustain the training stresses. The structural stress calculations were done by Dipl.-Ing. Ludwig Wondrak, and the aircraft was built in 1934 by the Akaflieg Graz. With profitable winds flights up to 30 min could be performed at the gliding slope near the Neusiedlersee (Neusiedler Lake).
