The MGB8555HV is a waterproof ultra high speed and torque brushless digital servo, part of MacGregor's range of high voltage servos designed for General use in RC Aeroplanes, Cars & Helicopters.
MacGregor's HV servos are designed with motors and electronics that operate off the direct voltage of a 2-cell Li-Po, Li-Ion, or Li-Fe receiver battery pack. This eliminates the need for a regulator and lowers the chance for a power failure that can cause a catastrophic failure of your model. Also note that the HV servo specs are shown at the higher voltage (8.4V 2S LiPo) but will still operate on a standard 5-cell 6V NiCd, Ni MH battery with a reduction in performance of approximately 10% in speed and torque.
