The Ka 1 was the first aircraft designed by Rudolf Kaiser (1922-1991), a successful sailplane designer.

He built the first copy of the plane during 1951/1952 in his parents´ attic. The goal was to design a sailplane that was small, simple to build and handle. Its small dimensions and light weight are typical. Kaiser piloted the sailplane on its maiden flight on Easter 1952 from the Wasserkuppe in the Rhön. A total of 10 of these aircraft were built according to Kaiser´s plans by various manufacturers.
