Design and development
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.[3][4] It has a manually rectractable center landing gear, a steerable tailwheel and detachable outrigger landing gear.[4] Spoilers are available to reduce lift.[4] The wingtips of the parked aircraft can be unlocked and folded inwards by a single person to reduce required hangar space.
