Based on recent expensive experience it is also a good idea to add a port protection IC on the wCK bus side. This is suitable:

The wires on the wCK are not particularly good, and in combination with metal frames and 11.1V LiPo, shorts and cut wires can cause major damage. The protection device will help protect the MCU, though a series 47R resistor on rxd (data out to wCK) will help too. The Protector will also go some way to protect the servos, which otherwise appear to have no protection.
Great pictures
