XC-ESC XC-E4990-1650 Sensored Brushless Motor – 1650KV 3-8S for 1/7 and 1/8 RC Cars
The XC-ESC XC-E4990-1650 is a powerful large-can sensored brushless motor designed for high-performance 1/7 scale RC cars, trucks and heavy-duty 1/8 monster trucks. With its 1650KV rating and 3–8S LiPo compatibility, this motor delivers strong torque, high power output and smooth controllable performance for demanding RC applications.
As part of the XC-ESC Sensored Brushless Power System range, the XC-E4990-1650 is designed to work with compatible sensored brushless ESCs. The sensored design allows the ESC to detect the rotor position accurately, resulting in smoother start-up, precise throttle response and more predictable power delivery. This gives the driver better control during acceleration, braking and low-speed manoeuvres, especially in heavy and high-power RC vehicles.
The 4990 motor size provides high torque capacity and strong thermal mass, making it suitable for demanding large-scale setups, heavy vehicles, larger tyres and high-load driving conditions. The 1650KV rating offers a strong balance between speed, torque and efficiency when used with 6S to 8S LiPo power systems.
The 4-pole rotor design delivers strong torque, efficient power delivery and responsive throttle behaviour. This makes the XC-E4990-1650 a strong upgrade option for large on-road cars, trucks and heavy-duty monster trucks where power, control and durability are essential.
For best performance, the XC-E4990-1650 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.
