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 Power HD 1900MG is a high-quality servo with a torque of 1.5 kg-cm (20.8 oz/in) at 6.0V and a speed of 0.08 sec. It operates at a voltage range of 4.8 ~ 6.0 DC Volts and weighs only 14.0 g (0.49 oz). It features a DC Motor and Copper Gear Type.

• Micro sized for small applications

• Copper gears

• Fast speed of 0.08/sec at 6V

In this video, Hamish gives a step-by-step guide on installing a Servo and how to avoid stripping your servo gears.
