ABSTRACT:
A radio remote control system for a model drive unit such as a model plane or the like is disclosed which is capable of eliminating retrimming of the same controlled object of which the trim adjustment was completed to substantially simplify the troublesome trim adjustment. The system includes a trim control voltage code memory which serves to separately readably stores therein trim control voltage codes representing trim control voltages of trim controllers concerned with a previously controlled object, so that the trim control voltage codes corresponding to the positions of the trim controllers during the previous control operation may be read out from the memory during recontrol of the previously controlled object. The system may also include a digital adder for carrying out addition of the trim control voltage codes of the previously controlled object read out from the memory and the trim control voltage codes concerned with the same controlled object currently controlled.
