Overview

Please Note

Servos are powered by the ESC's output to the receiver. If you're using a higher-strength servo than the ESC can support (usually greater than 20kg), you may experience 'brown-outs' where the radio signal can be interrupted and cause erratic driving. This can be helped by plugging a Glitch Buster into the receiver smoothing the current delivery. However, in some cases, you may need to install an external BEC.

Unleash the ultimate steering power in your 1/5 scale vehicle with the Power HD WB-100KG Brushless Servo. This absolute monster is built for one purpose: to deliver the immense torque needed to control the biggest and heaviest RC cars and trucks on the market. With a staggering 100kg-cm of torque on tap, this servo has the muscle to turn massive wheels with authority, giving you precise control where other servos would fail.

The WB-100KG is engineered for durability and performance. It features a powerful and efficient brushless motor, a super-strong, full steel gear train, and a full aluminium case for maximum strength and heat dissipation. Despite its incredible power, it's also impressively fast, with a transit speed of just 0.08 seconds. If you're looking for the definitive servo upgrade for your 1/5 scale beast, the WB-100KG is built to handle the punishment.
