Introduction
To understand what The Servo Gizmo does you need to understand a bit about servo basics. A long time ago when the radio control hobby was young, someone invented a scheme for sending control information via radio signal. This signal needed to convey the position of a control on a transmitter to an actuator on the model.
Description
The actuator is called a "retract servo" because it can extend or retract a control rod.
