Application(s): Pan drive for kite aerial photography (KAP) rig

Comments: This servo is a rare example of a continuous rotation (CR) 360degree servo in the 'micro' format.
It is lightweight and responds well to direct radio control.
Under pulse control (e.g. Gentles clickPan Pro) it is very slow and responds in very short steps.
