The Kadiak KC-2 Speedster is an American single-seat, radial engined homebuilt biplane designed prior to World War II.

Design and development

[edit]

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 95 hp (71 kW) Velie M-5 5-cylinder radial engine,[2] later replaced with a similar but more powerful 90 hp (67 kW) Lambert, and was designed for engines up to 145 hp (108 kW).

Operational history

[edit]

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]
