RWD 10

The RWD-10 was a Polish aerobatics sports plane, single-seat parasol wing monoplane, used from 1933 to 1939 and constructed by the RWD team.

Development
The aircraft was designed as a single-seater aerobatic sports plane that could also be used as a trainer for fighter pilots. Its chief designer was Jerzy Drzewiecki of the RWD design team at the DWL (Doświadczalne Warsztaty Lotnicze) aircraft factory. 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 of the fuselage, it turned out to be a successful design, completing 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 the Gordon Bennett Cup in ballooning on September 14–15, 1935 in Warsaw.

In 1936, the LOPP paramilitary organization ordered 20 aircraft, the purchase funded by a public collection for aviation development. They were built in 1937 and then distributed among the Polish regional aero clubs - the largest number going to the Warsaw Aero Club. In 1938, another two were built. In total, approximately 22 serial RWD-10s were produced.

Three aircraft crashed before the war, the rest were probably destroyed during the Invasion of Poland in 1939.
