XC-ESC XC-E4278-2250 Sensored Brushless Motor – 2250KV 3-6S for 1/8 RC Trucks
The XC-ESC XC-E4278-2250 is a powerful sensored brushless motor designed for demanding 1/8 scale RC trucks and monster trucks. With its 2250KV rating and 3–6S LiPo compatibility, this motor delivers strong torque, high power output and controlled throttle response for drivers who need serious performance in heavier RC vehicles.
As part of the XC-ESC Sensored Brushless Power System range, the XC-E4278-2250 is designed to work with compatible sensored brushless ESCs. The sensored design allows the ESC to read the rotor position accurately, resulting in smoother start-up, precise throttle control and predictable power delivery. This gives the driver better control during acceleration, braking and low-speed manoeuvres.
The 4278 motor size offers increased torque and power capacity compared with smaller motor classes, making it well suited for 1/8 trucks, monster trucks and high-load RC applications. The 2250KV rating provides a strong balance between speed and torque, especially when used with 4S to 6S LiPo power systems.
The 4-pole rotor design delivers strong torque, efficient power output and responsive throttle behaviour. This makes the XC-E4278-2250 a strong upgrade option for drivers who want powerful acceleration, dependable performance and smooth sensored control in demanding 1/8 scale vehicles.
For best performance, the XC-E4278-2250 should be paired with a compatible XC-ESC E-Series sensored brushless ESC. This combination allows the driver to benefit from smooth sensored operation, precise throttle feel and advanced ESC tuning possibilities.
