Sportavia (Fournier) RF-5
The Sportavia Fournier RF-5 was a powered sailplane which was produced during the mid-1970’s. It was a logical development of the earlier single-seat RF-3 and RF-4 motor gliders. A motor glider has a small engine which enables the aircraft to take off under its own power, as opposed to the classical glider take-off method using a winch or towing aircraft. At altitude, the engine can be switched off for soaring. If needed the engine can be engaged again to enable the aircraft to increase flight time, climb to higher altitude or as a safety measure in case of adverse soaring conditions..
The RF-5 was of wood construction with a retractable main wheel in the fuselage and fixed wing outriggers. Normal powerplant was a 68hp Limbach Comet four-cylinder four-stroke motor, driving a twin-blade, fixed-pitch prop. The aircraft seated two in tandem and was fitted with dual controls.
