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 sub-micro servo weighing less than 1/4 of an ounce. We also offer several unique servos:
- The Parallax continuous rotation servo is a Futaba S148 servo that has been modified for continuous rotation, giving you a quick and easy way to get your robot rolling.
- 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 Joinmax digital servo has 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!
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.
