Product Details

In The Box
  • (1) Xerun motor
  • (1) sensor wires (80mm / 120mm)
  • (1) pinion gear
  • (1) set of factory premium grade wires


  • ROAR approved
  • Innovative 4-pole-8-magnet "staggered pole" rotor (Hobbywing-patented) with low cogging effect and torque pulsation greatly improves control feel around corners.
  • Built-in chip for making the motor be easily identified by HOBBYWING ESCs. When pairing it with an HW sensored ESC (i.e. XR8 SCT/Plus), the motor can work in the “sensored” mode at all times with great output linearity after the identification. The Turbo timing is allowed to be activated for higher output.
  • Magnetic ring mounted on the rotor protects the motor from signal interference and guarantees its super stability in the “sensored” mode.
  • With the mechanical timing adjustable from 20 degrees to 40 degrees, users are able to have different output power.
  • Turbine design implemented by the rotor accelerates the internal air circulation and reduces heat.
  • Rebuildable design (partially rebuild-able) and a screw-less motor case for easy routine maintenance effectively prolong the motor life and raise the motor efficiency.
  • CNC machined aluminum housing, high purity copper windings, advanced rotor structure, high-quality alloy steel output shaft, high-precision bearings for high durability and smoothness.
  • New-style “U” solder tabs at the bottom of the motor for easy soldering and wiring.
