The Ka-7 is a two-place tandem trainer which has very effective dive brakes. It once held the multi-place world record for speed around a 500 km. Triangle at 84 kph/ 45 kt/ 52 mph, set in South Africa in 1964. It succeeded the earlier Ka-2 model, differing mainly by the introduction of a steel tube, fabric covered fuselage in place of wood/ fabric. A modified plan exists to lower the wings to the mid position and fit a one piece canopy, which makes the modified glider (Ka-7/ 13) look very similar to its successor, the Schleicher Ka-13. The lowering of the wings greatly improves the visibility from the rear.
