Castle Creations Mamba Monster X 8S 1/6 ESC/Motor Combo w/2028 Sensored Motor (800kV)


The Castle Creations Mamba Monster X 8S 1/6 ESC/Motor Combo with 2028 Sensored Motor is a great way to take you build to the next level with Castle’s cutting edge sensored large scale brushless power. The MAMBA MONSTER X 8S COMBO is ready to power any R/C vehicle weighing up to 25lbs, and running all the way up to 8S LiPo. This motor and ESC combo is designed for heavy, high speed rigs, and you'll experience smooth low-end control, without sacrificing power, punch, or speed.

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.

The ESC was designed with a robust aluminum casing, and the epoxy potting guarantees protection around the circuitry and ensures all-weather use. Mamba Monster X 8S is a beast, ready to take on the harshest of environments and still perform. 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.

When paired with the Castle sensored 2028-800KV motor, users with heavy, high power rigs will experience controllable low-end control 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.

NOTE: This is not a direct replacement to the Mamba XLX. The XLX still handles rawer full throttle power in the most extreme setups.

Product Use Statements:

  • Recommended battery capacity for 1:6th scale vehicles is 5000mah. Castle recommends using 50C continuous discharge or higher LiPo batteries.
  • Surge ratings should never be used to determine a pack’s suitability for a brushless application.
  • Castle recommends a high current connector designed for high-powered electric systems, rated for 100+ amps, such as Castle CC Bullet 6.5mm, CC Bullet 8.0mm, or 6.5mm Polarized Castle Connectors.
  • Applying voltages higher than 33.6V will cause irreparable damage to ESC.
  • Although Mamba Monster X 8S is waterproof, it is NOT intended for operation while completely submerged in liquid. Always rinse the ESC with clean water after exposure to corrosives or dirt.
  • The cooling fan must be removed prior to driving in wet conditions. *Fan is not waterproof.
  • Monitor motor temperatures closely; overheating a motor will cause permanent damage to the magnets. Never exceed 180° F on the motor or ESC.
  • The 2028-800KV is a 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 recommends 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 the Running & Maintaining document in the resources tab above for info on running and maintaining motors in wet environments.
  • Application Guidelines: Mamba Monster X 8S and 2028-800Kv motor is intended for use in 1:6 scale vehicles weighing up to 25 lbs. and up to 8S LiPo.  Vehicle Examples: Traxxas™ X-Maxx & Unlimited Desert Racer; Arrma™ Kraton 8s & Limitless; Losi™ Super Rock Rey & Audi R8; Redcat™ Shredder (optional motor mount and modifications may be necessary to install motor).
