  • Red oxidation metal casing provides strong heat dissipation during use
  • Compact 54.5mm x 20mm x 47.5mm size weighs only 68g

High-torque digital servo for RC and DIY projects

The LORDWORLD servo delivers 20 kg.cm of torque at 7.4 V, making it suitable for radio-controlled models and maker builds that need strong, precise actuation. Its full metal gear train improves positional accuracy and extends service life compared with plastic-gear alternatives.

180° rotation with metal-case heat dissipation

The output shaft travels a full 180° under digital control, giving accurate angular positioning for steering, robotic joints or camera gimbals. An oxidised red metal shell acts as a heatsink, helping the motor sustain high loads without thermal throttling.

Compact 54.5 mm x 20 mm x 47.5 mm form factor

At 68 g the unit adds minimal mass to lightweight airframes or mobile robots, and its narrow 20 mm profile fits tight chassis spaces. Builders needing more than 180° of travel or a different voltage range will have to look elsewhere.

Questions about this item

Will the 20 kg.cm torque at 7.4 V work with my existing 6 V receiver and BEC?

The servo is rated for 20 kg.cm at 7.4 V; running it at 6 V will reduce available torque and speed, so a 7.4 V capable power source is recommended for full performance.

How can I verify the 180 ° rotation is accurate after installation?

Command the servo to its end points and measure the physical travel; it should move through a full 180 ° range with the digital control providing precise positioning at each step.

Does the package include mounting horns, screws or a waterproof connector, or must I buy them separately?

The 68 g servo with its 54.5 × 20 × 47.5 mm red metal case is supplied as the motor unit only; mounting hardware and any specialised connectors are not included and must be sourced separately.
