Engineered from the ground up, the Mamba XLX2 ESC is packed with a potent combination of hardware and software advancements, sensored performance, CRYO-DRIVE and waterproof design that will set a new standard for high performance power systems for large-scale RC vehicles. 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, taking thermal performance to a whole new level. The results are more power handling, cooler ESC temperatures and longer runtimes and for ultra-high performance. Additional tuning flexibility awaits you with on-the-fly adjustments from your transmitter via the Auxiliary wire. Simply connect the white signal wire to an open radio channel and enable the feature in Castle Link by selecting what Auxiliary function you would like to use. Access programming parameters such as Torque Control, Max Brake or Max Throttle. Pairing the Mamba XLX2 with the Castle 4-POLE 12-SLOT SENSORED 2028-800KV or the 2028-1100KV will allow 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. You'll put more power to the ground, where it should be, instead of wasting it through raw heat and RPMs. Please refer to the Mamba XLX2 Product Use Statements (in document section) for information regarding calibration, input voltage, minimum battery requirements, wiring, soldering, connectors and more. It is critical that all relevant components in your system be able to support the incredible power handling and performance of the XLX2.
