The HD-8312TG is a premium standard-size servo with plenty of torque and speed. Digital electronics combined with a coreless motor, titanium-shielded aluminum gears, and two ball bearings give this servo a distinct edge over typical standard-size servos. The 8312TG works with standard RC servo pulses at frequencies up to 333 Hz. The 12″ (300 mm) lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. The picture below shows an example of the hardware that might be included with this servo (hardware might vary).
