N7516U - Schleicher Ka6-CR

Click HERE for the Ka6CR handbook.

The series began with the 14 m. Ka 6. This was followed by the Standard Class (15 m.) Ka-6b, with skid, and Ka6Br with main wheel. The Ka-6B won the OSTIV prize for the best Standard Class design at the 1958 World Championships at Leszno, Poland. The 6c version was a 6b with modified wing root. It has more of the wing covered with plywood and incorporates other minor improvements, and also comes in skid and wheeled (-6cr) models. All models have airbrakes for approach control. Some later 6CR models are designated as Ka-6CRPE's, the PE standing for pendulum elevators (the all-moving tail used on the Ka-6E). Heinz Huth of Germany won in the Standard Class at the 1960 Koln-Butzwelerhof, Germany and 1963 Junin, Argentina World Championships in Ka-6's. In 1963 two Ka-6's were flown 876.0 km./ 544.3 miles by Karl Betzler and Otto Schauble from Germany to France, setting a world distance record, and in 1964, Wally Scott of the U.S. flew his Ka-6CR to a world goal of 837.7 km./ 520.55 miles.

The Ka-6E was produced concurrently with the Ka-6CR for three years. The Ka-6E has, compared to the earlier 6CR, a longer canopy a lower fuselage (cross section reduced 10%), a modified leading edge prodile and an all-moving tail. Hans Werner Grosse of Germany, flying a Ka-6E as a guest, was the highest scoring pilot at the 1965 U.S. Nationals. Wally Scott won the 1967 Barringer Trophy by flying 888 km./ 552 miles in a Ka-6E. One belongs to the National Soaring Museum.

N9156 - Schleicher Ka7 Trainer (SOLD)

Click HERE for the Ka7 handbook.

N9156 was registered as D9156 in Germany before she made the trip across the pond this year (2008). Frank was lucky to have N9156 available in the FAA registry. This K7 was built in Germany in 1962. The fuselage is of steel tube construction with fabric covering. The wings, horizontal stab and control surfaces are all wood construction with fabric covering.

This K7 has been upgraded to be more like the later K13. The nose skid was replaced with a K13 nose wheel assembly. The seats were replaced with nice K13 fiberglass buckets and the main landing gear was replaced with a K13 assembly. It now has rubber doughnut shocks like on a Mooney. This helps save the instructors back during those hard student landings.
