Its output shaft is equipped with two ball bearings to reduce friction. The servo is compatible with standard RC servo pulses, delivering an operating angle of around 180° within a servo pulse range of 600 µs to 2400 µs. Additionally, it comes with a 12" (30 cm) cable that features a standard [JR-style connector](https://core-electronics.com.au/jr-connector-pack-female.html) that is Futaba-compatible.
