Castle MOTOR/REGLER COMBO MAMBA XLX2,8S 33.6V ESC - 1721-1260KV SENS. 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 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.
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.
Note: While many users have utilized the Mamba XLX2 in extremely high speed applications and drag setups, it is NOT intended for this application. As such the Castle warranty does NOT cover failure when used in high speed or drag applications.
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-performance 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.

Tech Tips:
|
The Mamba XLX2 has threaded mounting holes on the bottom of the ESC. There are four M3 mounting holes with a maximum depth of 5mm; they are spaced 46mm wide and 40.2mm long. Use this template for assistance in alignment and screw hole positioning.
Note: While many users have utilized the Mamba XLX2 in extremely high speed applications and drag setups, it is NOT intended for this application. As such the Castle warranty does NOT cover failure when used in high speed or drag applications.
Always double check that all connections are tight and secure before each use. Motor and battery bullet connectors will loosen up over time from vibrations, g-forces and use. A loose connector will cause increased resistance, this can lead to arcing or stress on the electronics and lead to failure.

Tech Notes: |
Running modes: Sensorless and Sensored
Water Resistant Design: The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. Castle recommended applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments. |
