RC flying airplanes 1950s-1960s

These are some home movies taken by my father, Joe Unger, in the 1950's and early 1960's showing very early remote control (RC) airplanes in action. The earliest models had large transmitters that sat on the ground and the planes were controlled by turning the rudders with escapements. Later, reed-based radios with hand-held transmitters allowed "full house" control of throttle, ailerons, rudder and elevator. Later in the video my Dad is shown holding his custom designed plane with pink and black silk and dope finish. He flies aerobatics using a reed radio. His friend Carl Mohs is flying his rudder and elevator controlled model with diesel engine.
