The Fournier RF-5 is a two-seat motor glider designed by René Fournier.
The RF-5 is based on the single seater Fournier RF-4, and is a low-winged monoplane of all-wooden construction, with the crew of two sat in a tandem enclosed cockpit. It is semi-aerobatic with loops, stall turns, lazy eights, chandelles and spins approved. It has a manually rectractable center landing gear, a steerable tailwheel and detachable outrigger landing gear. Spoilers are available to reduce lift. The wingtips of the parked aircraft can be unlocked and folded inwards by a single person to reduce required hangar space.
An improved high-performance version. Powered by a 50.7 kW (68 hp) Limbach SL 1700 E Comet engine.
A high performance powered sailplane with 17.5 m (57 ft) span wings.
