Eagle Model A-129: Similar to the A-1, but with a five-cylinder Kinner radial engine.
Different models were powered by varying combinations of Wright, Ryan-Siemens, Kinner, Comet, and Pratt & Whitney engines, a large engine in the nose of the aircraft and two smaller "helpers" under the wings in nacelles supported by struts.
On May 25, 1915, pioneer pilot and aviation designer, Otto Timm crashed in a field in Magnolia, Minnesota owned by Kinner.
In 1932, Harlow worked for Bert Kinner becoming his chief engineer in the design of the Kinner Playboy, Sportwing, and Speedwing.
