Power HD micro servo HD-1900A with extra-long servo horn.
This is a great general-purpose actuator for tiny mechanisms. 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. The pictures above show an example of this included hardware (hardware might vary). You can find more information about this servo under the specifications tab and in its datasheet (187k pdf).
If you are looking for a similar servo that is capable of continuous rotation speed control as opposed to limited-range position control, consider the FEETECH FS90R micro continuous rotation servo, which has almost the same weight, speed, and torque as the HD-1900A.
Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.
