Kinner (US)

Winfield B. (Bert) Kinner was a well-known aircraft and engine manufacturer beginning in 1919. He is reported to have experimented with engines like the small Lawrance three-cylinder radials as early as 1921. Kinner Motors Co. of Glendale, California was a 1939 successor to the Kinner Airplane and Motor Corp., which was founded in 1927. The company is well known for their five-cylinder radial engines. The entries here are two HOAE development programs, which began during WWII, but did not lead to success. Kinner bought Gladden Products of Glendale in late 1944. Kinner Gladden Products Corp. engines were listed for the last time in J51-52.

N/A -- {N/A / N/A / NA} / {N/A / N/A / N/A}

2cyl; Kinner Twin; 50hp@N/A rpm; 1943-1945; Wt = N/A; TC = none.
According to aircraft historian John Underwood in Sk#82(4/07), it may have been developed for the Lockheed Little Dipper prototype [NX18935], which is known to have flown with a twin-cylinder Franklin O-110 (2A-112) and a four-cylinder Continental O-110 (A-40). The Kinner Twin was not put into production, but Underwood says that an example was owned, at one time in the past, by the late Rod Nimmo, a Lockheed engineer and light aircraft/air racer designer.
