The Xerun 1/8th Competition G3 Motor & ESC Combo pairs the Xerun 4274 SD G3 2250Kv sensored brushless motor with the XR8 Plus 150A ESC. The optimised motor structure improves efficiency by more than 6% and reduces running temperature under load.

The motor sensor system adopts patented "error-free" Hall sensor technology with an independent high-speed, high-precision encoder that outputs a pure and accurate rotor position signal, isolating external interference. The motor also minimises cogging and small torque pulses at low RPM and carries an IP5X dustproof rating.

XeRun XR8 Plus and 4274SD motor combo overview

The Xerun 4274 SD G3 motor paired with the XR8 Plus 150A ESC provides competition-grade performance for 1/8th scale vehicles.

Error-Free Hall Sensor

The motor sensor system adopts patented 'error-free' Hall sensor technology with an independent high-speed and high-precision encoder.

Brushless electric motors and ESCs have large amounts of torque at any given RPM. Using too-tall gearing, or a vehicle that is too large or heavy, can result in damage and/or product failure. Please consult your manual and select gearing suitable for the vehicle and terrain, as damage caused by overloading or abuse is unlikely to be covered by the manufacturer's warranty. Always monitor your ESC and motor temperatures closely after modifying your system to ensure they stay within safe operating limits.
