Talk:Servo (radio control)

Stuff to add:

 * Referencing


 * Digital servos, where they start to use on-board PID control


 * Smart servos, where a digital servo is also tunable for the speed and control parameters


 * Servo internal drives - moulded plastic gears through to metal gears and ball races


 * Servo motors - recent development in high power, low weight motors


 * Servo case sizes


 * Example speed / torque figures


 * Possible merge servo control ?
