RE: Whats The Right Servo?
Before computer radios, we mechanical Servo Savers on Throttle Linkages, in particular. The Throttle Pushrod would pass through an EZ Connector on the Throttle Servo Arm, and there would be Springs on either side of the EZ Connector held in place by Wheel Collars. When you moved the Throttle Stick, the Throttle Servo Arm would move and when the Throttle Arm, on the Carb, came to a stop, the Springs would Compress and prevent the Servo from Binding. There are other uses for Servo Savers, but being able to set End Points, or Travel Volume, has reduced or eliminated the need for them.
