Vernon MacNabb, deceased, was a pioneer of license-free radios for model airplanes. Vernon built Free Flight and Control Line models before establishing the Citizen-Ship Radio Corporation in 1950. Citizen-Ship was created to develop and manufacture license-free radios at 465 megacycles, considered impossible at the time.
Vernon’s work with the 465-megacycle band was demonstrated at the Texas Nats in 1950. The new frequency helped revolutionize license-free Radio Control flying, and he made significant contributions in the field of vacuum tube technology.
