LRP X45 Modified 2100KV 1:8 Motor

The LRP X45 Modified 2100KV 1:8 Motor (SCH-LRP520822) is purpose-built for the demanding world of 1/8 competition racing. Delivering powerful performance with exceptionally smooth, controllable power delivery and strong, finely adjustable braking, it helps extract maximum pace and precision over long runtimes. A precision-machined aluminium case underscores its competition focus, finished in a distinctive two-colour anodised scheme that pairs matte black with LRP blue, complete with crisp X45 engraving.

Engineered for consistency and durability, the closed motor design, maximised case surface area and very low heat generation support long stints and stable output. An adjustable timing range from 0° to 15° can be set for both CW and CCW rotation, letting you fine-tune response to track conditions, vehicle setup and driving style. Inside, a dual-axis dynamically balanced sintered rotor with an extended mounting surface ensures high mechanical stability, while two compact precision ball bearings keep operation smooth and low in vibration. An optimised multi-layer PCB minimises internal resistance, and the waterproof LRP PreciSensor system delivers precise sensored operation with any compatible speed control, with added benefits when paired with an LRP unit. IFMAR approval confirms the platform’s racing credentials.

With 4S LiPo input and a compact 42 mm diameter can, this 4-pole, multislot design targets the performance envelope needed for modern 1/8 electric competition.
