The Fischer RW-3 was essentially a powered glider of mixed wood and metal construction, with fabric covering. The cantilever mid-wing is swept forward while the T-tail assembly acts as a mount for the propeller. The main wheels are retractable manually as is the semi-retractable nose wheel.
The first prototype RW-3 A-1, D-EJAS, was wrecked in June 1956 and a second was built.
RWF formed at Porz-Westhoven, near Cologne, in early 1950s to develop a new light aircraft, the RW-3 Multoplane, basically a powered sailplane with Porsche engine driving a propeller mounted between the fin and rudder, and under the tailplane. The production license was subsequently transferred to Rhein-Flugzeugbau GmbH.
It is powered with a Porsche 678/4 aircraft powerplant, a flat-four opposed piston engine with a reduction gearing of 1.981, a takeoff-power rating of 75 hp at 4600 rpm (propeller 2320 rpm), and max continuous power rating of 65 hp at 4500 rpm (propeller 2070 rpm). Leaned out, it delivers 55 hp at 4100 rpm (propeller 2070 rpm), with fuel consumption in economy flight mode 3.7 US gph.
This RW-3 Multoplane was demonstrated in England during August 1958.
