In 1928, Kinner Airplane & Motor Corp. constructed a light multi-purpose aircraft for Dr. Thomas Carlyle Young, a renowned surgeon and chairman of the Western Aero League. This unique aircraft, designated the Kinner Courier, was the sole example built and received the special name “Spirit of Ether” (NC4618).
Design and Features
The Kinner Courier was designed as a two-seat, strut-braced high-wing monoplane. It was powered by a 100 hp Kinner K-2 engine, providing adequate performance for its intended roles. A notable feature for practical hangar storage was its foldable wings.
Later Modifications
In 1930, Dr. Young entrusted the aircraft to students at the Curtiss-Wright Technical Institute. There, the Kinner Courier underwent modifications, including the installation of a new radial engine equipped with a Townend ring for improved aerodynamics.
