Mamba XLX2, 8S, 33.6V ESC, 20A Peak BEC with 1721-1260KV Motor

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 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.

The Mamba XLX2 and 1721-1260kv combo is designed for 1/6th and 1/7th scale vehicles weighing up to 25lbs and up to 8s LiPo. The 1721-1260kv is a great upgrade option for the Traxxas X-Maxx and Arrma Kraton 8s. It is more powerful than the stock motors, but not crazy overpowered like our 2028 series motors. The 8mm output shaft is designed to handle the increased power of this larger motor; but does require an 8mm bore, Mod-1 pinion. It is also a great upgrade for the Arrma 1/7th scale on-road cars, IE Limitless, Infraction, Felony.

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 run times and for ultra-high performance.

NOTE: Due to the high power nature of the XLX2, you must use appropriately sized batteries and connectors. We recommend a minimum 150 amp connector for the XLX2; examples include Castle 6.5mm polarized, EC8 and QS8. DO NOT USE XT90, Traxxas, EC5/IC5 or any other connectors rated below 150 amps continuous.

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.

Pairing the Mamba XLX2 with the Castle 4-POLE 12-SLOT SENSORED 1721-1260KV 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.
