"The first contest for Radio Control model airplanes was in 1937; however, it was not until the 1970s that this form of aeromodeling became popular.
In this portion of the gallery, visitors can see how radio control has developed from the first rudder-only models to pylon racers, aerobatic models, and helicopters"
Elmer Wasman placed third with this airplane, the White Mystery, at the first radio control contest in 1937. (next) This case contains a reproduction of the radio transmitter and receiver used by the Good brothers to fly the Guff."
Here is some pix of old RC radios and here a video I found on youtube
