Claim One:
1. A helicopter pilot trainer comprising, in combination, (1) a free-flying, scale model of a helicopter having its flight controls operated and controlled by means responsive to radio signals transmitted from a remote flight station to a radio receiver in said helicopter, and (2) a flight station comprising a substantially actual size simulation of a helicopter cockpit with its associated individual flight controls, and means responsive to the operation of the flight controls at the flight station for converting said operation into a radio signal transmitted to the radio receiver in said scale model helicopter to effect an operation of the flight controls in the scale model helicopter corresponding to the operation of the controls at the flight station, said means responsive to the operation of the flight controls at the flight station comprising an electro-mechanical interface associated with each flight control and physically separated from said radio transmitter, the electro-mechanical interface providing an adjustable mechanical linkage between the particular individual flight control and a potentiometer in said electro-mechanical interface to vary the output of the potentiometer in response to the operation of the individual flight control, with the output of the potentiometer being fed to the radio transmitter to transmit the controlling radio signal to the radio receiver.
