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.

|
|
| Product Use Statements |
|
|---|---|
| Calibration: |
Individual transmitter signals for neutral, full throttle, and full brake vary. You must calibrate your Castle ESC so that it will operate effectively with your transmitter. Anytime the ESC is powered up with a new transmitter or with different throttle channel settings, it will need to be calibrated to the transmitter’s throttle settings. The ESC may also need to be calibrated after updating to new software via Castle Link. |
| Input Voltage: |
Applying voltages higher than 33.6V will cause irreparable damage to your Mamba XLX2 controller; DO NOT RUN HV CELLS (above 4.2v/cell) WHEN RUNNING AT MAX CELL COUNT (8s). This will exceed the 33.6v rating and will damage the ESC and not be covered by the warranty. |
| Battery Capacity Minimum: |
The Mamba XLX2 is a high-performance controller; you must use high-discharge cells in your high-performance application to ensure vehicle performance. Recommended battery capacity is 5000mAh. We recommend using 50C continuous discharge or higher LiPo batteries. |
| Wiring and Soldering: |
High strand count silicone coated copper wire is essential with higher power electric power systems. Castle Creations' wire is lower resistance than the same diameter of solid copper, meaning more power gets from the batteries to the motor with less wasted as heat. The ultra-high strand count and silicone coating means the wire is very flexible which prevents work hardening and breakage with use. |
| Connector Ratings Minimum: |
The Mamba XLX2 requires the use of connectors designed for 150+ amps continuous. Ex. Castle 6.5mm polarized or 8mm bullet. |
| Motors: |
The Mamba XLX2 is capable of handling incredible amounts of power, your motor must also be up for the task. Always run your motor within the manufacturer’s specs. Monitor motor, battery, and controller temps carefully and never let the motor get above 200° F. Excessive heat in the motor can damage the motor, the Mamba XLX2, and the batteries. 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. |
| Gearing: |
If you change your vehicles gearing, motor, or battery, check your motor, ESC and battery temperatures often on the first run. If components get too hot, increase the spur size, reduce the pinion size, or reduce the pack voltage. |
| Castle Link Settings: |
During the optimization of your setup it is critical to check motor and ESC temperatures after making adjustment. The heat limit threshold for Mamba XLX2 ESC is 200° F and Castle motors is 200° F. We recommend the use of the data log as you progress with the feel and power of the vehicle. You will be able to record real-time data such as motor RPM, battery current and voltage, ESC and motor temperature, throttle input, and more. Download and analyze the collected data via Castle Link and make adjustments to maximize both performance and battery life. |
| AUX Wire: |
The AUX wire allows you to adjust a setting “on-the-fly” using an auxiliary channel on your receiver. The AUX wire function is disabled by default and is programmable via Castle Link. Plug this wire into the auxiliary (#3/#4) channel on your receiver.
|
| Operating Environment Considerations: |
Although Mamba XLX2 is waterproof, it is not intended for operation while completely submerged in liquid. Always rinse the ESC and motor with clean water after exposure to corrosives or dirt. While the motor and controller may be waterproof, we suggest users confirm that the rest of their vehicle, including the batteries, servos, radio and chassis are also waterproof before exposing them to liquids of any kind. **The cooling fan must be removed prior to driving in wet conditions. It is not waterproof. |

| 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. 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. |

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. |
| Application Guidelines: | See above in ESC specs. |
| Max. Recommended Vehicle Weight: | Vehicles weighing less than 25lbs. |
| 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. |
