Power HD 4.4g Sub-Micro Servo HD-1440A

The HD-1440A analog servo from Power HD is one of the smallest servos we carry and is a great, inexpensive, tiny actuator for a small robot mechanism. Servo horns and associated hardware are included.

The lead is terminated with a standard "JR"-style connector, which is Futaba-compatible. Mounting screws and an assortment of servo horns is included with this servo (hardware might vary). You can find more information about this servo on the datasheet.

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