Overview

The Power HD S15-S is a high-voltage, low-profile brushless servo designed for precision and power. With its impressive torque, lightning-fast speed, and durable metal gears, it is perfect for demanding applications like 1/10 scale crawlers, drift cars, and other high-performance RC vehicles.

Note

Servos are powered by the ESC's output to the receiver. If you are using a higher-strength servo than the ESC can support (usually greater than 20 kg), 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 to smooth the current delivery. However, in some cases you may need to install an external BEC.

Features

  • High voltage (HV) compatibility for increased performance
  • Powerful torque output (16.5 kg-cm at 8.4V)
  • Ultra-fast brushless motor for quick response
  • Durable titanium and steel gears
  • Low-profile design for tight spaces
  • Genuine Power HD product
