We carry a wide variety of servos, all of which are compatible with our servo controllers except for the Surplus Hitec HS-5475HB servo. The sizes range from a giant-scale servo with up to 583 oz-in of torque to a micro servo weighing less than 1/4 of an ounce. We also offer several unique servos:

The GWS S35 STD continuous rotation servo is a servo that has been designed for continuous rotation, making it a great actuator for beginner robotics projects.
Our Surplus Hitec HS-5475HB servos have had their control electronics removed, but each offers a high-quality servo casing, 3-pole ferrite motor, and heavy-duty Karbonite geartrain complete with two ball bearings, all at a heavily discounted price.
The BCM servo and Joinmax Digital servo have a rotating arm in the body of the servo in addition to the typical output shaft at the top of the servo.

Whatever your application, we probably have a servo for it! Our parametric search of our assortment of servos can help you find the servo you’re looking for.

Note: The servos must be connected to a servo controller, RC receiver, or microcontroller to be used. All of the servos have Futaba or Futaba-compatible cable connections.
