The LRP X45 Modified brushless motor series was specifically developed for the demanding requirements of 1/8 competition racing. It combines powerful performance, precise vehicle control and exceptionally smooth, highly controllable power delivery with strong and finely adjustable braking performance that remains consistent even over long runtimes.
The precision-machined aluminum case highlights the uncompromising competition-focused design of the X45 motor series. For the first time, the two-colour anodized finish combines matte black with LRP’s signature blue, while the X45 engraving completes the premium appearance. High-quality materials and outstanding workmanship meet the demanding technical requirements of a modern 1/8 modified brushless motor.
The combination of a closed motor design, maximized case surface area and very low heat generation demonstrates the motor’s uncompromising engineering approach. This allows the X45 to deliver long runtimes, high durability and consistently strong performance.
The adjustable timing range from 0° to 15° enables fine tuning of the motor characteristics to suit track conditions, vehicle setup and driving preferences. Timing can be adjusted for both CW and CCW rotation, providing high flexibility for different car concepts.
The dual-axis dynamically balanced sintered rotor features a shaft design with an extended mounting surface for high mechanical stability. Two compact precision ball bearings ensure smooth, vibration-free operation and long service life, while the optimized multi-layer PCB reduces internal resistance.
The waterproof LRP PreciSensor system ensures precise sensor operation with any sensored speed control and offers additional benefits when used together with an LRP speed control.
