In 1956, Kaman began to diversify as an aerospace subcontractor of McDonnell Douglas, Grumman, and others. In the mid-1960s Kaman diversified outside of the aerospace industry, using the expertise Kaman had gained in composite materials and the end of the need for skilled woodworkers to craft wooden rotor blades. Charles Kaman, a guitarist as well as an aerospace pioneer, worked with his engineers and other musicians to create the round-backed, composite-body Ovation guitar, which led to the eventual creation of Kaman Music (now KMCMusicorp). Kaman Music was an independent distributor of musical instruments and accessories, and a major producer of guitars and guitar parts and accessories.
Charles Kaman founded the company in December 1945 with $2,000 of capital and his invention of the servo-flap controlled rotor.
