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.
Deliver immense power and precision to your high-demand RC vehicle with the Power HD WT120 standard brushless servo. This heavy-duty unit is engineered for extreme applications, featuring a potent brushless motor that operates on high voltage up to 8.4V. At this power level, it produces a staggering 50.0 kg-cm (694.4 oz/in) of torque with a rapid transit speed of just 0.08 seconds, providing both brute strength and incredible responsiveness.
The WT120 is built for durability and efficient heat management. Its standout feature is the full brass case, which provides exceptional rigidity and acts as a massive heat sink to keep the motor cool under heavy loads. Inside, a robust steel geartrain supported by dual ball bearings ensures a long and reliable service life.
Weighing 120 g (4.23 oz) and fitting a standard servo footprint, this servo provides the strength and resilience needed for large-scale crawlers, monster trucks, and other demanding applications. It is also compatible with programming boxes for further customisation.
