K7 wing being recovered, showing the wooden structure.
The K7 was intended as a two-place trainer with good performance, a rare combination in trainers of its time.
The K7 is constructed with a welded steel tube fuselage, covered in doped aircraft fabric covering. The wing is a wooden structure with a doped fabric covering and employs a Goettingen 533 (16%) airfoil at the wing root, transitioning to a Goettingen 533 (14%) section at the wing tip. The wing features powerful dive brakes. The landing gear is a fixed monowheel. The earlier Ka-2 variant has a plywood monocoque fuselage.
After 550 had been built, the K7 was superseded in production by the Schleicher ASK 13.
The K7 can be converted into a K7/13 with a conversion kit to lower the wing to the mid-wing position and installation of a one-piece canopy, rendering the aircraft similar to the ASK-13.
