About fifty were built and the type became well known as an aerobatic aircraft, performing at many displays in the hands of pilots like Gerhard Fieseler.
In November 1925 test pilot Antonius Raab and engineer Katzenstein formed the Kassel-based company that bears their name.
[1][2] The Schwalbe was a single bay biplane with thick sections, unequal span wooden wings which were built around twin spars and fabric covered.
The wings had marked stagger and were braced between the spars with forward leaning, steel tube, N-form interplane struts.
The lower wing was attached directly to the lower fuselage, from which the inner upper wing was braced with an outward leaning pair of parallel struts to the spars and held over the upper fuselage by a pair of inverted V-struts, one on each side, to the forward spar alone.
[1] A large, almost triangular tailplane was mounted on top of the fuselage and carried generous, curved and balanced elevators.
