FISCHER RW-1. In Western Germany, the past few years have produced a number of original light and ultra-light prototypes. Those which have reached the flight trials stage include the Heini Dittmar HD-153 Motor-Move (developed from the HD-53 Segel-Move sailplane), the Fritz Raab-designed and Puetzer-built Moraa and the Scheibe SF-23 Sperling two-seaters, plus the powered-gliders, the Burglengenfeld-built Me 06 Motor-Segler and the DKW pusher-powered, high-wing FIBO 2a. The last-mentioned is a 1951 design, with tandem main wheels.
The Fischer RW-3 is thus the second post-war German light aircraft to employ pusher power. The RW-3 is essentially a powered glider of mixed wood and metal construction, with fabric covering. Three versions are envisaged, the prototype A-1, for development as a motorised sailplane; the A-2 as a club primary trainer and the A-3 as a shorter span, advanced and aerobatic trainer.
Salient features : Of pleasant overall aspect. the RW-3 possesses several uncommon design features. The cantilever mid-wing is swept forward to improve low-speed characteristics, while the Tee-shaped tail assembly acts as the mounting for the propeller which is driven by the engine sited in the rear fuselage . The main wheels are retracted manually as is the semi-retractable nose wheel. First prototype wrecked in June, second is now flying.
