GWS S35 STD Continuous Rotation Servo

The GWS35 continuous rotation servo is a standard-sized servo that has been built by GWS for continuous rotation. Since servos have their own integrated control circuitry, this unit gives you an easy way to get your robot moving.

This servo has now been replaced by the SpringRC Continuous Rotation Servo which is more powerfull and features an easily accessed potentiometer to adjust rest point.


The GWSVO008B S35 STD continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. It can be controlled directly by a microcontroller without any additional electronics, which makes it a great actuator for beginner robotics projects. Since these servos keep spinning they are ideal to use with our servo wheels to create a full drive system for a robot without any extra electronics. Simply plug the servo into a microcontroller and get forward,reverse with speed control.

The servo has an 11" (270 mm) lead that is terminated with a JR-style connector and comes with the following included hardware:

  • 1x small X-horn
  • 1x large X-horn
  • 1x large wheel
  • 1x 6-star horn
  • 1x double-arm horn
  • mounting hardware: 4x grommets, 4x eyelets, 4x screws
  • 1x horn mounting screw

This robotics servo is compatible with our servo controllers and has a Futaba-compatible output shaft, which means it works with our servo wheels.
