The ASK 13
This glider is a school bi-plane of the company Alexander Schleicher aircraft, which was developed by Rudolf Kaiser out of the Ka 7 in 1965. The first flight of the prototype took place on the Wasserkuppe in July 1966. At that time it had the identifier D-5701.
In the period from 1966 to 1980 a total of 617 copies were built. There are also about 80 licensed buildings that were built in Oerlinghausen or in individual associations. However, there were always smaller deviations, e.g. B. when rounding the nose, with the rudder or the surface formation to the fuselage.
