The Traxxas High-Torque 400 Red servo combines maximum steering authority with a long list of high-performance features. The servo utilizes full metal gears, dual ball bearings, and an aluminum center section for added heat dissipation. A cutting edge brushless motor provides 400 ounce-inches of torque for extreme applications. The High-Torque 400 servo is fully waterproof, not just "water resistant" and drops into most 1/10 Traxxas vehicles for that perfect factory fit.

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.
