Overview

Power HD brings a range of crawler specific high-torque & high-voltage servos. With three variants; 40kg/cm, 30kg/cm, & 20kg/cm featuring a waterproof case & wiring system.

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.

Features

  • Servo case is CNC machined, ensuring higher quality
  • Customised Power HD waterproofing system
  • Uses Hardened Steel Gears for extra strength and durability
  • The 32-bit high-frequency MCU creates more precise operation with locked-rotor & power-on slow-start protection
  • Casing is anodized in Blue
