Putting the X in Extreme!


Mamba XL X  is a 1:5 scale controller capable of 3S - 8S LiPo, with a 20 amp peak BEC. Paired with our NEWLY REDESIGNED Castle 2028 800kv SENSORED brushless motor (sensorless operation required with this ESC) this is the perfect upgrade for 1:5 scale RC  hobby vehicles (including gas to electric conversions) weighing up to 30 lbs for 2WD and 25 lbs for 4WD.

  • 3S-8S LiPo
  • For use in vehicles up 30lbs (2WD) and 25lbs (4WD)- with battery, ready-to-run.
  • 20AMP peak BEC, user adjustable from 5V to 8.4V
  • Data Logging can be downloaded via the Castle Link USB programmer; you can use the Quick Connect Duo (sold separately) to allow you to access both wires into a single Castle Link connection. You can then analyze this data and make adjustments to the ESC to maximize both performance and battery life.
  • Auxiliary Wire Functionality allows for “on-the-fly” adjustments such as torque control and max throttle, while driving, right from your transmitter.  The AUX wire function is disabled by default but is programmable via Castle Link. Once you have programmed the functionality of the AUX wire, that setting can then be adjusted on-the-go from a compatible transmitter.
  • Additional capacitors to protect against ripple current
  • Audible alerts for error conditions
  • Smooth sensorless startups with an ULTRA-EFFICIENT sensorless mode.

Product Features
Enabled by default, the Mamba XLX captures and records performance data from your vehicle. This allows you to view a detailed turn-by-turn record of what your ESC actually experienced during the run. 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. You can use the Quick Connect Duo (sold separately) to allow you to access both wires into a single Castle Link connection. 
Auxiliary Functionality:
