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.

Power HD fresh D12 reverse receiver wire low-profile servo specific for touring cars & drift cars. It features an all-aluminium case and distinctive laser pattern on the bottom, durable titanium and steel gears, a powerful Coreless motor and it pulls up to 12.5kg-cm of torque at a speed of 0.059s, weighs only 55g, support SSR mode. With receiver wire leaving the case on the opposite side of the output gear–and thus on the inside of the chassis in most cases – wiring can be carried out much neater compared to standard servos that always have the wire on the “outside” of the chassis. Therefore the servo is the ideal choice especially for 1/10th touring cars and drift cars, as it makes for more tidy and safer wiring.
