The FW-5 was a cantilever low-wing monoplane, it had an unusual wing planform in which the wing centre-section was blended into the fuselage, this gave rise to the name The Wing. It had a fixed tailwheel landing gear and was powered by a 3250NaN0 Avco Lycoming flat-six piston engine. The enclosed cabin had room for a pilot and three passengers. First flown in 1942 only two aircraft were built.
