[edit] Development
The aircraft was designed in 1935 by Andrzej Anczutin of the RWD bureau, as a light and economical sports plane. The plane was a wooden low-wing monoplane, with two seats side-by-side in a closed cockpit, powered by 50 hp Walter Mikron I straight engine.
The prototype was built and first flown in early 1936 (registration SP-AXY), funded by the Polish division of Osram factory. The plane did not appear a successful design, though. Test revealed lack of directional stability, therefore its rudder was much enlarged, the wings were fitted with fixed slats and a windshield was redesigned. It did not improve the situation much, and in 1937-1938 the prototype was rebuilt and fitted with stronger 60 hp Avia 3 engine in a lengthened nose, while the vertical stabilizer and rudder were made smaller. Most significant feature became a front windshield with a negative slope.
After final changes, the prototype still was not satisfactory, but it served as a basis for the RWD-16bis design, which was a new, redesigned aircraft, produced as the RWD-21.
