The HD-1501MG is a powerful standard-size servo that features metal gears and two ball bearings and can deliver a tremendous amount of torque for a servo this fast (if you need even more torque than this, check out the larger 1235MG giant servo). The 1501MG works with standard RC servo pulses, providing a running angle of approximately 165° over a servo pulse range of 800 µs to 2200 µs, and it has a 10″ (25 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible
