High-Torque Digital Servo

The LORDWORLD HPS-2018MG is a new digital servo rated at 20KG·CM torque at 7.4V. It features metal gears, dual-ball bearings, and a high-precision potentiometer for accurate positioning. An anodized aluminium case aids heat dissipation and reduces power draw. The unit weighs 68g and measures 40*20*40.5mm.

For RC Vehicles and Robots

This servo suits builders working on 1/6, 1/8, 1/10, or 1/12 scale cars, robots, boats, or aircraft. Its IP67 rating allows operation in wet conditions. Projects needing a different voltage range, a smaller form factor, or a continuous-rotation motor should consider other options.

20KG·CM Torque at 7.4V

The peak torque of 20KG·CM at 7.4V is the key figure for matching this servo to your load requirements. Verify that your power supply can deliver the necessary voltage and current for this rating. The 25T spline metal horn is included for direct attachment.

Questions about this item

Will the metal gears or the 25T servo horn need periodic replacement under heavy use?

The servo uses full metal gears and a 25T metal horn designed for extended service life; the high-precision potentiometer improves linearity so wear is minimal compared with standard plastic-gear servos.

What is the first limit reached during continuous high-torque operation at 7.4V?

The anodized aluminum case provides excellent heat dissipation, reducing power consumption and allowing sustained 20KG.CM torque without thermal throttling under normal RC loads.

How much audible noise and heat does the servo produce when running all day in a robot?

Dual ball bearings and the metal gear train keep noise minimal, while the aluminum housing dissipates heat efficiently so the unit stays cool during extended operation.
