The Rudolf Kaiser designed Ka-3, which first flew in 1956, was a development of the earlier Ka-1 with a steel fuselage instead of wood. The wood and fabric wing, steel tube and fabric fuselage Ka-3 has top surface spoilers for approach control and main skid, but no wheel.
Schleicher also offered the Ka-3 in kit form.
