R/C Servo Motors

I have been in the field of R/C radio control toys for about two years. One important component is the Servo Motor. Really it is equally important in Robot Toy control.

The control pulse is simply a pulse width from 1.0 ms to 2.0 ms.
When pulse is 1.5ms, the servo will go to the midway. No need to provide pulse if you don't want to change the position, it will lock on the last valid pulse received.

R/C plane, car, boat all use it to control the direction.
