   Scheibe SF 33 'Trainer'

Information supplied by Noël Rumers

The Scheibe SF 33 „Trainer“ is a further development from the SF 29. It was constructed specially for easy flying so that not experienced pilots could fly it too. It was first flown in 1977.         

The fuselage is a welded steel tube construction, plywood covered on the rear upper fuselage and totally covered with cloth. The wing, elevator and rudder are an all-wood construction also covered with cloth. The landing gear is a fixt one-wheel construction with a supporting wheel under each wing. It has a steering tail wheel. 

The engine was the 2-cylinder-4stroke BMW motorbike engine with 900cc and it had, with reduced power 35HP at 3500 RPM. The engine operated with normal super car petrol.

Only one SF 33 was built. In Germany it was flown with the licence number   D-KOCH. After a motor gliders contest it was sold to the USA and flown with the licence number N-233SF. In September 1984 it was sold again to Canada, where it was flown under the licence C-GLWK.
