The Kinner Sportster was a 1930s American light monoplane built by Kinner Airplane & Motor Corporation.

Design and development

The Kinner Airplane & Motor Corporation had been producing radial engines since 1919 decided to enter the light aircraft market. The first design was a single-seat low-wing monoplane the Kinner Sportster K with a fixed tailwheel landing gear. Further versions followed with different engines. The strut-braced, low-wing, open cockpit, conventional gear aircraft featured folding wings.[1] In 1933, an improved version the Sportwing B-2 was introduced. An enlarged four-seat version was produced in 1935 as the Kinner Envoy. Kinner became bankrupt in 1937 and rights to the Sportster were acquired by the Timm Aircraft Company. The Sportster was also produced after the Bankruptcy by Security-National Corp as the Security S-1 Airster

Sportster K is an earlier version of the B1 with the only difference being it was powered by the 100 hp (75 kW) Kinner K-5 engine. The Sportster B-2 had the wings clipped to 35 ft and was powered by the 125 hp B5 engine. After Bert Kinner was forced out - he founded the Security Aircraft company and produced the Security Airster which was a very close copy of the Sportster. Timm purchased the rights to and manufactured several Sportsters under the Timm name. Later the airframe design was used by the Call-air corp. and finally design elements of the Sportster can be found in the Piper Pawnee ag aircraft.
