In 1925, the Cox-Klemin Aircraft Corporation introduced a light amphibious flying boat, designated as the CK-18. This aircraft was not an original development by the firm, but rather the realization of the NUA-1 project by the renowned French aviator Charles de Nungesser.
Design and Funding
The construction of the CK-18 was financed by businessman John Stelling, which is why the flying boat received the name “Stelling Amphibian.” Despite its innovative design and the involvement of notable figures, the model failed to attract the expected commercial interest.
Legacy and Final Fate
No orders were received for the amphibian, and the Cox-Klemin firm soon ceased to exist. The single CK-18 unit, bearing registration number NC2059, was sold to Richmond Airways Inc of New York. However, in 1931, the aircraft failed its relicensing process and was subsequently disassembled.
