JX PDI-1181MG 17g Digital Servo 3kg 0.13sec Metal Gear For 1/18 RC

Product Overview

If your stock plastic gear servo in 1/18 to 1/12 scale RC car is stripping out or feels sluggish when steering, this is the best value replacement. It features a tough all-metal gear train, a digital processing chip, and a compact 17g mini form factor. It delivers crisp, immediate steering response with minimal dead band, eliminating steering wobble and ensuring precise control.

Upgrading your servo is a high-return investment to improve handling for a low cost, especially for off-road bashers operating on rough terrain that demands extra steering torque. This upgrade benefits entry-level RC enthusiasts, budget bashers, and scale crawler builders using WPL and MN trucks.

The PDI-1181MG accepts up to 6.0V high-voltage input for enhanced torque and speed. However, most budget-conscious users rely on a standard 5V input. Even at 4.8V, the PDI-1181MG delivers 3.0 kg-cm of torque and a 0.13-second speed, which is a major upgrade over stock units. Please check your chassis dimensions for fitting before purchasing.
