FEETECH Standard Servo FS5103B
The FS5103B is a general-purpose, low-cost standard analog servo from FEETECH. Two ball bearings help reduce friction and improve performance. Servo horns and associated hardware are included.
This servo can work with both 5 V and 3.3 V servo signals.

The FS5103B is a general-purpose standard-size analog servo from FEETECH. The output shaft is supported by two ball bearings for reduced friction. The FS5103B works with standard RC servo pulses, providing a running angle of approximately 180° over a servo pulse range of 600 µs to 2400 µs, and it has a 12″ (30 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible.
For more advanced robotics applications, please note that we also carry a version of this servo that is specially modified to provide access to the feedback potentiometer through a fourth (green) wire, which lets you monitor the actual position of the servo from your controller:

Datasheet for the FEETECH Standard Servo FS5103B (133k pdf)
Note: while this datasheet lists the 6 V stall torque as 3.2 kg*cm, Feetech has since revised this to 3.8 kg*cm based on more recent measurements (this is also more in line with their listed 4.8 V stall torque of 3.0 kg*cm).
