With the K 10 Rudolf Kaiser brought together the desires of the contest pilots for an all-moving (pendulum) elevator, thought to have a little less drag, and the improved flight performance of the Ka 6 B-S modifications.
Because of the need to pay more attention to flying the aircraft, caused by the pendulum elevator, the K 10 was not popular. Finally, Rudolf Kaiser made pilots happy with the subsequent K 6 E, which led to a great success with this aircraft.
