The DS120M digital servo from Power HD, a high-quality servo with digital control electronics for increased performance, is one of the fastest standard-size servos we carry, and it has plenty of torque, too. The output shaft is supported by two ball bearings, and all of the gears are metal for increased durability. Servo horns and associated hardware are included.
Key specs at 6 V: 0.11 sec/60°, 178 oz-in (12.8 kg-cm), 56 g.
The HD-DS120M is a great high-performance, fast actuator with plenty of torque. Digital electronics coupled with all-metal gears and two ball bearings give this servo a distinct edge over similarly sized servos, especially if you need high speed and power. The lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. The pictures below show the metal gear train and an example of the hardware that might be included with this servo (hardware might vary).
Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.
