About the Aircraft
The Ka 8 was derived from the earlier KA 6 design as a simple single-place sailplane with dive brakes using construction techniques similar to the Schleicher KA 7, simplified for amateur construction from kits. Emphasis was on rugged construction, good climbing ability in thermals and good handling characteristics.
The prototype Ka 8 made its first flight in November 1957 and over 1,100 were built in three main versions. The original Ka 8 had a very small canopy. Side windows for improved visibility were introduced in the next version, and the Ka 8B, by far the most numerous variant, has a larger one-piece blown Plexiglas canopy. The Ka 8C features a longer nose, larger main wheel located ahead of the center of gravity and deletion of the larger wooden nose skid resulting in a roomier cockpit.
The cantilever high wings are single-spar structures of pine and plywood, with a plywood leading edge torsion box and fabric covering aft of the spar; the forward sweep is 1° 18' and dihedral is 3°. There are Schempp-Hirth air brakes in the upper and lower surfaces and the wooden ailerons are plywood covered. The cantilever tail unit is of similar construction to the wings, with ply-covered fixed surfaces and fabric-covered rudder and elevators, and a trim tab in the elevator is an optional fitting. The fuselage is a welded steel-tube structure, with fabric covering over spruce longerons and a glass fibre nose cone.
About the Model
The model features built-up construction using Blasa and Plywood. Covered in Oracover as is usual on Seagull models.
