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.

The Savox SW-1212SG Plus is an exceptionally powerful and durable servo designed for demanding RC applications. Its massive torque, waterproof design, coreless motor, and blistering speeds make it a top choice for 1/8 scale buggies, monster trucks, and other applications where brute strength and precision are essential.
