The DS-3688HB is a great high-performance, fast actuator for small mechanisms. Digital electronics coupled with mostly metal gears and two ball bearings give this servo a distinct edge over similarly sized servos. The lead is terminated with a standard “JR”-style connector, which is Futaba-compatible.
