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.{{cite journal|journal=Flight International|date=11 June 1970|pages=974–977|url=http://www.flightglobal.com/pdfarchive/view/1970/1970%20-%201062.html|title=GROWN-UP ULTRA-LIGHT |accessdate=18 January 2015}}{{cite web | title=RF 5 Flight Manual |url=http://www.club-fournier.de/dev/wp-content/uploads/2012/09/RF5-POM-5111.pdf |accessdate=23 November 2017}} It has a manually retractable 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.
