The Kinner Airster built for Amelia Earhart, 1923. Amelia Earhart's second airplane was this Glendale-built Kinner Airster. It was very much an experimental proposition. The engine was a Kinner-copy of the Wright Gale, forerunner of the Whirlwind, but it was anything but a success. It threw more oil than it consumed and vibrated excessively. The experience gained from Earhart's flying helped Kinner build a better engine and by 1930 he was a leader in the field.
