The Kadiak KC-2 Speedster is an American single-seat, radial engined homebuilt biplane designed prior to World War II.
The KC-2 was an original design of Everett E. David, built in 1931.[1]
The aircraft was built with a welded steel tube fuselage, wooden wings, and fabric covering. It originally used a 950NaN0 Velie M-5 5-cylinder radial engine,[2] later replaced with a similar but more powerful 900NaN0 Lambert, and was designed for engines up to 1450NaN0.
The designer sold the KC-2 in 1939. It was storm damaged post-war, rebuilt and re-licensed, remaining active until at least 1977.[2]
