Improving upon the design of the TW-2, engineers Charles Cox and Alexander Klemin introduced the CK-2 training aircraft in 1924. This model was a two-seat, single-strut biplane of mixed construction, initially equipped with a 150 hp Hisso A engine.
Development and Initial Trials
The prototype of the CK-2 was handed over to the military for comparative trials at Wright Field. However, the CK-2A variant failed to impress the customer and was returned to the Cox-Klemin Aircraft Corporation.
Upgrades and Lack of Interest
Attempting to rectify the situation, a more powerful 400 hp Liberty engine was installed on the aircraft. Despite this upgrade, this new variant, designated CK-2B, also failed to generate interest from the military.
