Mamba XLX2, 8S, 33.6V ESC, 20A Peak BEC w/2028-1100KV Motor

Introducing the Mamba XLX2, an ESC that will redefine the limits of 1/5th scale R/C! Engineered from the ground up, the Mamba XLX2 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. The Mamba XL family is well known for its extreme performance capabilities. The XLX2 pays homage to the legacy of its predecessors and exceeds their performance on all levels.

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.


You can easily optimize the ESC for any driving condition, from rugged terrain to smooth pavement to the perils of rock and gravel. Create, save and download setup profiles through the Castle Link Programming Suite on your Windows PC, or wirelessly with the convenience of the new B-Link Bluetooth Adapter and Castle Link app for Android or iOS.


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.


Sensored 1/5th scale is here! Pairing the Mamba XLX2 with the Castle 4-POLE 12-SLOT SENSORED 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.

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.
