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-DRIVET 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 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. CRYO-DRIVET, 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. 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 WindowsT PC, or wirelessly with the convenience of the new B-LinkT BluetoothT 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! SmartSenseT 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. MAMBA XLX2 FEATURES: Input Voltage Range 3S-8S LiPo (33.6v max) Sensorless, Sensored, SmartSenseT and Brushed Running Modes Powerful Integrated 20A Peak Adjustable BEC (5.25V-8.0V) CRYO-DRIVET Technology minimizes the amount of time the ESC’s electrical components spend generating heat, resulting in improved thermal performance during partial throttle operation where the majority of driving occurs ESC is housed in a rugged CNC aluminum case and potted in waterproof epoxy to protect the electronics and promote efficient heat transfer Premium forged heatsink with elliptical fins for superior air flow and increased heat dissipation Oversized factory equipped thermally controlled 50MM cooling fan Compatible with S. 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. 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. Castle 6.5mm polarized or 8mm bullet. 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. 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. You MUST connect the AUX wire to an open channel on your receiver even if you are not using the Auxiliary function. You MUST disconnect the AUX wire from your radio before connecting to Castle Link. Failure to do so may result in damage to your Castle Link and/or computer. 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. Note: Some vehicles may require aftermarket parts to allow ESC and/or motor fitment. Input Voltage Range: MIN: 3S LiPo, MAX: 8S LiPo 33.6V Running Modes: Sensored, Sensorless, Brushed and SmartSenseT when paired with a Castle 4-POLE 12-SLOT Sensored Motor. Brake: Proportional Reversible: Yes, but may be disabled for racing. Telemetry Link Capable: Yes, with Castle Creations Telemetry Link for S. BUS2 and Futaba T4PX, T7PX and T7PXR Transmitters. 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. Motor Specs Input Voltage Range: 12S max (8s max with XLX2) Kv: 1100 Max. RPM: 45,000 Motor Size: Length: 4.4″ (113.2mm) Diameter: 2.2″ (57mm) Shaft Size: Length: 30mm Diameter: 8mm Weight (w/wires): 44 oz. Items Needed for Operation: N/A Product Use Statements: N/A Application Guidelines: N/A Max. Recommended Vehicle Weight: Vehicles weighing less than 30lbs. 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. After 7 days, an unpaid item case will be opened. Details About This Item. Brand New In Factory Packaging. Our customer service is friendly and here to help you!
