Power HD 1501MG High-Torque Metal Gears Servo 60g/ 17kg-cm

The Power HD 1501 MG based on a metal-geared analog servo. This is from Power HD that delivers extra-high torque normally associated with much more expensive or larger servos. This is one of the most prominent standard-size servos featuring metal gears and two ball bearings. It is capable of providing a tremendous amount of torque for such a high-speed servo. At 4.8V this servo offers a stall torque of 215 oz-in, whereas at 6.0V it is 240 oz-in. This stall torque value indicates it as a strong stepper motor.

1501 supports standard RC servo pulses, providing a running angle of approximately 165° over a servo pulse range of 800 µs to 2200 µs. And it consists of a 10″ (25 cm) cable terminated with a standard JR-style connector, which is Futaba-compatible. In the Power HD 1501 MG, the default servo pulse widths usually 1ms to 2ms may not give full 180 degrees of motion. Under this condition, we need to set the servo controller to custom pulse lengths as  0.75ms to 2.25ms. But care should be taken if use shorter/longer pulses there is a chance to break your servo.
