Overview
The Power HD S range has been specially designed for the high demands required in all classes of racing including 1/10 and 1/8th off road. The latest technology allows these servos to operate in SSR mode (Super Speed Response) allowing a natural feel and instant feedback on track. The new design has more accurately machined gears than ever before, offering more precision and reliability to meet the ever increasing demands of the competition racing market.
Note
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.
