Power HD Micro HD-1250MG 3.5k Metal Geared Servo
Servos are powered by the ESC's output to the receiver. If you are 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.
Learn how to install a steering servo correctly to increase steering performance and avoid stripping your servo gears out.
