ABSTRACT:
A device for controlling the movements or operating cycles of models, for example, model airplanes, model ships, kites, etc., which are driven by a drive motor is provided which includes a screw spindle which is affixed at about the center of a shaft which is coupled with the motor drive shaft. An internally-threaded element, preferably a nut, is longitudinally guided on the screw spindle for actuating the operating cycle in one or the other direction. At the two protruding ends of the shaft, a spiral spring is disposed which urges a washer against the screw spindle in such a way that when the element becomes unscrewed from either end of the screw spindle, the element is retained in a free-running position, and during the reverse rotation of the motor drive shaft, the element is pushed in a counter direction whereupon it is screwed onto the screw spindle.
