The R-1 was an experimental twin-engine monoplane with variable- incidence wings, first flown with normal wings on 16 December 1949, and with articulated wings in 1951.
Original patents taken out in 1938 and an aircraft built in 1940, but was destroyed during the war. Two prototypes were built, of wooden construction, powered by two Renault 6R engines.
The outer wing panels are articulated on an oblique hinge-line and these orientate automatically in turbulent air, the varying incidence absorbing the loads imposed.
