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 FS5106B 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.
An aluminum servo horn that works with this servo is available separately:
Power HD SR8 Aluminum 25T Servo Horn.
You can find more information about this servo in its datasheet (133k pdf).
Note that, as with most hobby servos, stalling or back-driving this servo can damage it.
Comparison to the Power HD 3001HB servo
This servo is a lower-cost alternative to the 3001HB from Power HD, which has nearly identical dimensions and similar performance. The two servos should be generally interchangeable for most applications. The picture below shows both the FS5103B and the 3001HB side by side:
