This Kinner radial model airplane engine was built by Charles Harty, of Colorado, in the 1990s. Mr. Harty used construction articles published in Strictly IC magazine to produce his version of this 1/4 scale Kinner K5 radial engine. It has a 1.062 bore and a 1.312 stroke for a total displacement of 5.8 cubic inches. It sports a dry sump lubrication system, burns gas on spark ignition, and will spin a 22 x 10 propeller up to 4,500 rpm.
The Kinner Airplane & Motor Corp., California, began building 5-cylinder engines in 1919. The company also built light aircraft from 1931 to 1937. In 1939, the company changed its name to Kinner Motors and produced engines for thousands of World War II training aircraft.
