The FS5115M is a standard-size analog servo from FEETECH can deliver more than twice the torque of the other same-size servos with plastic gears thanks to its powerful motor and all-metal gear train. The output shaft is supported by two ball bearings for reduced friction. The FS5115M works with standard RC servo pulses, providing a running angle of approximately 180° over a servo pulse range of 500 µs to 2500 µs, and it has a 12″ (30 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible.
