This digital servo offers exceptional speed without sacrificing torque, delivering standard-servo torque in a miniature size. The output shaft is supported by two ball bearings for decreased friction. Servo horns and associated hardware are included.
Key specs at 6 V: 0.07 sec/60°, 58 oz-in (4.2 kg-cm), 26 g.
Overview
The mini high-speed digital servo GD-9257 is a fast actuator for small mechanisms. Since this servo was designed for demanding helicopter tail rotor control, it is one of the fastest servos available, yet it can deliver torque typically only found in bigger, slower servos. This servo features digital electronics and a coreless motor for higher performance and two ball bearings for reduced friction. The lead is terminated with a standard “JR”-style connector, which is Futaba-compatible.

Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.
Note: The manufacturer has changed this servo’s label slightly, from “GD-9257” to “GS-D9257”, though the servo itself is physically unchanged.
