Lerche and Wespe were proposed to OKL on February 2, 1945.

In 1940, Professor Erich von Holst discovered the aerodynamic principle of the radial lift force, by which wings rotating around the longitudinal axis of the aircraft provided lift and thrust.

In May 1944 he designed a senkrechtstarter jagdflugzeug for the firm Focke-Wulf. It was a helicopter with contra-prop rotors in the nose, probably equipped with a turboprop propulsion system like that of Focke-Wulf Peterle .

Unlike the tailsitter designed in 1938 by Otto Muck and by the American Arthur M. Young in 1941, the von Holst helicopter lacked fixed wings, flying in horizontal position with the tail depressed to transform part of the thrust into lift.
