SunFounder DS-S020 Digital Servo esepcially designed for RC Robot Cars Crawler Robot, Using advanced potentiometer and stainless steel gear material to make sure the high speed, strength and accuracy of the servo. It really realized high torque better than other seller same servo motor.


  • Large Torque - 25KG Servo Motor 6.0V (≥22 kg·cm) - 7.4V( ≥27 kg·cm)
  • High Rotation and Long Life - 180-degree rotation. Well-controlled from 0 to 180 degrees, and it can work for more than 200 hours.
  • High Precision - Using advanced potentiometer and stainless steel gear material to make sure the high speed, strength, and accuracy of the servo.
  • Fast Heat Dissipation - Make of half aluminum alloy frame design, small size, and high torque in order to cool the servo motor and good care for the servo motor when it is working
  • Widely Applications - Super high torque, higher precision, lower noise, prevent tooth sweeping, a good choice for high-speed vehicles, RC robots, and other automatical equipment.
