The HD-1581HB is the strongest micro servo we carry, and digital electronics coupled with a ball bearing give this servo a distinct edge over analog micro servos. The lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. The pictures below show an example of the hardware that might be included with this servo (hardware might vary).

You can find more information about this servo under the specifications tab and in its datasheet (453k pdf).

Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.
