From it later went out the Schleicher Ka 6E, in which, among other things, the pendulum tailplane of the Ka was taken 6 CR -Pe. It was also (to improve speed flight characteristics) the NACA 63 profile replaced by a Wortmann- profile of a FX 40 in a FX goes to the root outward 30.
To achieve the most accurate profile and thus a longer laminar air flow, presented the Vorderkantenbeplankung to 65 % of the wing chord and consisted of 2.5 mm thick plywood. The prototype of the K 10 (D - 3619 ) was first flown in 1963 ( test certificate dated 30 July 1963). Although demonstrated the testing that the use of the word man 's profile and caused by structural reinforcements weight increase of 25 kg at high speeds a large performance gain brought, but the flight characteristics at average speeds which the Ka 6 made so attractive among other things were bad. Therefore, the production of the K 10 was just twelve copies, which were built 1963-1964, set and Kaiser designed the Ka 6 E as a new version of the Ka 6, a synthesis of the harmonic flight characteristics of the Ka 6 CR and better services K should be 10.
