 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.

New from Power HD the TR-4! Having compatibility with high voltage 6V-8.4V, at 7.4V input the servo pulls up to 2.6kg-cm of torque at a speed of down to 0.10s. A long 35cm receiver wire and mini size of 22.5 x 12.5 x 24.0 mm ensures the servo is a direct fit in crawler Traxxas TRX-4 Crawler Range! The TR-4 servo comes with 25T metal spline and special gaskets making it waterproof for go-everywhere capabilities.
