Development
The aircraft was designed as a single-seater aerobatic sports plane, that could also be used as a trainer for fighter aircraft pilots. The main designer was Jerzy Drzewiecki of the RWD construction team in the DWL (Doświadczalne 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 stability was not satisfactory, but after modifications, including lengthening a fuselage, it appeared a successful design and it completed state trials in 1935. In a mock dogfight with the PZL P.11c fighter, the RWD-10 kept on the P.11's tail. The first public aerobatics show of the RWD-10 took place during a Gordon Bennett Cup in ballooning on September 14–15, 1935 in Warsaw.
In 1936, a series of 20 aircraft was ordered by the LOPP paramilitary organization, funded by a public collection for aviation development. They were built in 1937 and then distributed among the Polish regional aero clubs - most (5) for Warsaw Aero Club. In 1938, another two were built. In total, approximately 22 serial RWD-10s were produced.
Three aircraft were crashed before the war, the rest were probably destroyed during the Invasion of Poland in 1939.
