[edit] Development
The aircraft was designed as a single-seater aerobatics sports plane, that could also be used as a trainer for fighter aircraft pilots. Main designer was constructed Jerzy Drzewiecki of the RWD construction team in the DWL (Doswiadczalne Warsztaty Lotnicze) workshops. Its silhouette was similar to the RWD-8. The first prototype (registration SP-ALC), was flown in July 1933 by Drzewiecki. Its handling was not saticfactory, but after modifications, including lengthening a fuselage, it appeared a successful design. In a manoeuvre dogfight with the PZL P.11c fighter, the RWD-10 was keeping on P.11's tail. The first public aerobatics show on RWD-10 took place during an air meeting in September 14-15, 1935 in Warsaw.
In 1936, a series of 20 aircraft was ordered by the Polish civilian aviation, partly funded by a public collection for aviation development. They were built in 1937 and given to aeroclubs. In 1938, another two were built. In total, about 22 series RWD-10 were produced.
Three aircraft were crashed before the war, the rest were probably destroyed during the Invasion of Poland in 1939.
