The Mamba XLX2 and 2028-1100kv combo is designed for the most extreme and demanding RC applications. The massive motor and high power ESC are capable of pushing vehicles and drivers to their limits and beyond. This is the perfect combo for vehicles weighing up to 30 lbs and up to 8S LiPo.

CRYO-DRIVE™, Castle’s proprietary breakthrough technology, integrates unique software and dedicated hardware to reduce heat and dramatically increase performance. Thousands of times per second, the XLX2 software minimizes the amount of time the electrical components spend generating heat. These software advancements work in parallel with an open housing design which enables increased directional airflow to cool critical components. With the combination of a new 50mm fan and forged elliptical fin heatsink, the XLX2 maximizes airflow throughout the system.

Pairing the Mamba XLX2 with the Castle 4-POLE 12-SLOT SENSORED 2028-1100KV allows heavy, high speed rigs to experience controllable low-end ranges without sacrificing power, punch or speed. SmartSense™ mode uses the motor’s sensors to start the motor to provide smooth starts, excellent torque, and low-speed drivability. Once the motor is spinning, it seamlessly transitions to Castle’s ultra-efficient sensorless mode.

Do not use mounting screws that extend more than 5mm into the front of the motor. Using too long of a screw can result in damage to the motor’s windings and will not be covered by the warranty.

Your Castle ESC is warranted for one (1) year from date of purchase to be free from manufacturing and component defects. This warranty does not cover damages caused by abuse, including incorrect wiring, over-voltage, overloading, improper gearing, improper motor selection, incorrect controller settings, insufficient batteries, or inadequate connectors. Always monitor your ESC and motor temperatures during the first run after modifying your system to ensure they stay within safe operating limits.

WARNING: Drag and speed run setups are inherently abusive and exceedingly hard on all electronic components. Castle does NOT warranty products used in drag or speed run applications.
