Take your 1:6th scale build or upgrade to the next level with Castle’s legendary brushless power. The MAMBA MONSTER X 8S, 33.6V ESC W/2028-800KV SPONSORED COMBO is ready to take on any R/C vehicle weighing up to 25lbs, and running up to 8S LiPo.  Designed for heavy, high-speed rigs, you'll experience controllable low-end ranges, without sacrificing power, punch, or speed. 

Note: This is not a direct replacement for the Mamba XLX2. The XLX2 still handles rawer full-throttle power in the most extreme setups.

Drive fearlessly and punch that throttle! The MAMBA MONSTER X 8S utilizes Castle’s breakthrough technology CRYO-DRIVE™.  By reducing the rate at which the ESC heats up and removing heat more efficiently, your setup will be able to handle higher gear ratios, in heavier vehicles, with longer runs.  These software advancements work in parallel with a unique open housing design to allow increased directional airflow to cool critical components. With the integration of a 40mm cooling fan and a forged elliptical fin heatsink, the design maximizes airflow throughout the system, taking thermal performance to a whole new level.

High-performance demands high quality and this ESC was designed with durability in mind. Constructed around a robust aluminum casing, the epoxy potting guarantees protection around the circuitry and ensures all-weather use. Mamba Monster X 8S is a workhorse, it will dominate in the harshest of environments
.

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 Rock Race Mode. Optimize your vehicle for any racing or bashing application you can imagine!

When paired with the newly updated Castle  2028-800KV, users with heavy, high-speed rigs will 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.
