The Fafnir 2 took part in the July 1934 Rhön competition on the Wasserkuppe, from where it set a new world distance record on 27 July of when Heini Dittmar flew it to Luban in Czechoslovakia. It was the best glider of those at the 1934 Rhön, with a measured glide ratio of 26:1, a good figure for the time but not sufficiently outstanding to invite imitations, given the complexity and expense of the wing/fuselage blending. Nonetheless, even three years later Dittmar flew it to win the 1937 International Championships, held at the Wasserkuppe from 4-17 August and regarded as the first World Gliding Championships.
