Yahboom DS3218MG 20kg digital servo

The Yahboom DS3218MG is a 20kg digital servo built with full metal gears for RC models and DIY robotics. It delivers high torque in a waterproof housing and provides a 180° control angle for precise positioning. Hobbyists and makers use it for steering, robotic arms and other motion control tasks.

Capacity and headroom

Rated at 20kg of torque, the servo handles heavy control surfaces and multi-joint arms without stalling under normal loads. The 180° rotation range covers most standard RC and robotic articulation needs. Continuous operation at peak torque will generate heat and may exceed the gear train’s duty cycle.

Upgrade path

This servo replaces standard plastic-gear units that strip under load or lack the resolution for fine positioning. The jump is worth it when your current servos cannot hold position on large surfaces or when a project demands metal-gear durability and digital centering accuracy.

Highlights

  • 20 kg torque powers large RC models
  • Full metal gears resist stripping under load
  • Digital circuitry gives precise 180° positioning
  • Waterproof housing survives wet conditions
  • Included servo tester simplifies centre calibration

Questions about this item

Will the DS3218MG's 20 kg torque work with my existing 6 V receiver and standard PWM leads?

The servo uses a standard three-wire PWM connector and operates at common hobby voltages, so it plugs straight into your current 6 V receiver without adapters.

How can I verify the DS3218MG centres correctly and sweeps the full 180° after installation?

Connect the servo to the included Yahboom servo tester via Micro USB, run the centring routine, then command a full sweep; smooth movement to both end points confirms correct operation.

Does the package contain only the DS3218MG servo or does it also include the Yahboom servo tester and any mounting hardware?

The box holds one DS3218MG 20 kg digital servo with full metal gears plus the Yahboom 1-channel servo tester with Micro USB interface; servo horns and mounting screws are not supplied.
