Babcock Controls Inc. was a California based electronics manufacturer. This company was primarily focused on military projects, with a small side branch being low cost R/C remote control systems. Babcock built several innovative remote control systems in the early days of R/C model flying. At that time these were all tube systems. In the course of time, model aircraft production was discontinued in favour of military orders.
More by chance I came across an unused 1-channel system in tube technology, which I find visually very beautiful.
