Demonstration of a 1960's Galloping Ghost radio control system. A single "servo" is used and by a clever combination of pulse rate variation, pulse width variation, and mechanical decoding, three controls are achieved. There is some interaction between the controls and the throttle operation prevents independently using the rudder and elevator, but it does work. The constant pulsing motion really eats up the batteries and the system requires some mechanical tuning to get everything working correctly.
