Suitable for RC model aircraft and boats. Do not use in carbon wings with RDS. Voltage of potentiometer on the gear must be isulated to carbon parts.

Warning - Potential problems with this servo!

This servo features metal gears, and the potentiometer operating voltage is passed to the servo’s metal output shaft. If an aluminium control surface horn or a non-insulated RDS linkage is used with the servo, and if an electrically conductive contact with the airframe also exists - e.g. in an all-carbon model - the servos will interact with each, as the aforesaid voltage is transmitted between them. You can avoid this problem either by using a plastic control surface horn, or by insulating the servo mount in such a way that no electrical connection exists.
