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 T70 High Voltage Servo feature all-aluminium housings, with high-power brushless motor as the core power, offering amazing torque output. American imported ST32-bit MCU control chip ensure superior servo performance. The T70 is ideal for large truggy, rock crawler and 1/5th scale cars.
If you need something with a little less torque, the T50 is ideal for 1/8th nitro off-road.- Total Height (A) = 43.5mm

- Below Mount (C) = 27.5mm
- Above Mount (D) = 16.0mm

In this video, Hamish gives a step-by-step guide on installing a Servo and how to avoid stripping your servo gears.
- The PowerHD servo is equipped with a split servo lead. This includes a JST-PH 3-pin connector (in black) that carries a single signal wire (in white), and a power lead composed of a red/black wire that connects to a JST-PH 4-pin male connector (in white).
