Control system for radio-controlled aircraft. The control system includes a control master for simultaneously controlling a group of flight control means, for example, a group of ailerons. A control bar is slidably mounted in the control master and connected to a servo-controller. A plurality of controller cables or push rods, one for each flight control means in the group, are connected to the control bar. A sliding movement of the control bar effects a repositioning of the flight-control means.
