Abstract
A control servo includes a supporting frame, a motor, a driving shaft and a control slider. The supporting frame comprises a mount and a slider housing, wherein the motor is supported in the mount of the supporting frame. A driving gear is provided at an output end of the motor. The driving shaft is positioned longitudinally through the slider housing. A driven gear is provided at one end of the driving shaft to mesh with the driving gear. The driving shaft penetrates through the control slider while an upper portion of the control slider extends out of the slider housing. An electric brush is provided underneath the control slider. The control servo eliminates the use a potentiometer as installed in a traditional servo and the reduction gearbox so that the structure is simpler and lighter; thus it plays an important part in the miniaturisation of model aircraft.
