Kinner Airster

The Kinner Airster is an American two-seat single-engined biplane designed by Bert Kinner and built by his Kinner Airplane & Motor Corporation.

Development
The Airster appeared in 1920 designed by Bert Kinner, it was a one or two seat open-cockpit single-engine biplane. The first single-seat Airster was powered by a 60 hp Lawrance L-4 radial engine. When the prototype crashed on a test flight it was rebuilt as a two-seater with a wider cockpit. One Airster named The Canary was bought by Amelia Earhart while she was learning to fly. Later production aircraft had slab-sided plywood fuselages and were powered by a variety of 60 hp engines.

In 1927 the company produced a three-seat variant powered by a 100 hp Kinner K-2 engine, with the last Airster being built in 1927. Design rights were sold to the Crown Carriage Works in 1929 who produced a version designated the Crown B-3.
