Power HD Standard Coreless Motor Steel & Aluminum Gear Digital Waterproof Servo

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. How To: Install a ServoIn this video, Hamish gives a step-by-step guide on installing a Servo and how to avoid stripping your servo gears. Power HD brings a range of crawler specific high-torque & high-voltage servos. With three variants; 40kg/cm, 30kg/cm, & 20kg/cm featuring a waterproof case & wiring system. FeaturesServo case is CNC machined, ensuring higher quality. Customised Power HD waterproofing system. Uses Hardened Steel Gears for extra strength and durability.
