The FS0403 analogue sub-micro servo from FEETECH is a great tiny actuator for a small robot mechanism. Servo horns and associated hardware are included. Key specs at 6 V: 0.08 sec/60°, 10 oz-in (0.7 kg-cm), 5 g.
This is a great general-purpose actuator for tiny mechanisms. The FS0403 is a very small 5 g analogue servo from FEETECH (formerly known as Fitec) that offers position control over an approximate 120° operating angle for servo pulses between 900 µs and 2100 µs. As with most servos, the pulse range can be expanded to achieve an expanded operating angle, but the limits of this are not specified by FEETECH. (In our tests, we were able to get an expanded range of approximately 180° over a pulse range of 650 µs to 2500 µs, but as this is not part of FEETECH’s official specifications, it is possible different units will behave differently in this regard.)
The servo has a 6″ (15 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible, and it includes additional servo horns and mounting hardware.
You can find more information about this servo in its datasheet (97k pdf).
Note that, as with most hobby servos, stalling or back-driving this servo can damage

Most standard radio control servos (and all RC servos we sell) have three wires, each a different colour. Usually, they are either black, red, and white, or they are brown, red, and orange/yellow:
Please check the specs for your servo to determine the proper power supply voltage, and please take care to plug the servo into your device in the proper orientation (plugging it in backwards could break the servo or your device).
