Mamba Monster X Extreme 1:8 Scale ESC

Product #: 010-0145-00

UPC code:819326010989


The Mamba Monster X provides even more extreme performance than the Monster 2. Most notable is the addition of a new, programmable Auxiliary Wire that allows the user to make “on-the-go” adjustments to several settings, such as torque control and reverse enable or disable. This new Auxiliary Wire allows you to fine-tune the performance of your Monster X ESC right from your compatible transmitter using an auxiliary channel on your receiver. The Monster X also features updated Audible Alerts that will notify drivers of possible issues with their calibrations and error conditions to help diagnose problems in the field.  The ESC can also be configured to run sensored brushless motors in addition to sensorless and brushed. 

Mamba Monster X is a 1:8th scale and Monster truck controller capable of 2S - 6S LiPo, with an 8 amp peak BEC - and, it’s waterproof*, so you can run your vehicle through morning dew, across soggy snow, or a muddy trail. This is the perfect upgrade for 1:8 scale buggies, truggies and on-road vehicles as well as 1:10 scale monster trucks weighing up to 15 lbs.  It also comes standard with a highly efficient, 30mm ESC cooling fan.

  • Input Voltage range 2S-6S
  • Powerful integrated 8A Adjustable BEC (5.25V-8.0V)
  • Data Logging capability to capture and record performance data from your vehicle
  • Waterproof design for running in all weather conditions and elements.
  • Factory installed, fully removable 30MM cooling fan
  • Convenient transmitter programming for six common adjustable settings
  • Easily program and update ESC with use of Castle Link USB (coupon included for free USB with purchase) and freely downloadable Castle-Link Windows™ program.
  • Optional smartphone-based programming with the B-LINK™ Bluetooth Adapter (sold separately and Castle Link all available on Google Play or Apple App Store)
  • Telemetry Ready Compatible with 010-0152-00 Telemetry Link for Futaba S.Bus2 and Futaba T4PX and T7PX transmitters
  • Auxiliary Wire Functionality allows for “on-the-fly” adjustments such as Max Power and Max Brake.
  • Audible Alerts that will notify you of possible issues with calibrations and error conditions.

Product Use Statements:
*Although Mamba Monster X and Castle brushless motors are waterproof, they are not intended for operation while completely submerged in liquid. They can corrode   when exposed to corrosive materials, such as salt water. 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.

Telemetry Link Capable: Yes
Tech Notes:
  1. Mamba Monster X setups frequently hit 100+ amps in peaks and not all LiPos are created equal. Surge ratings should never be used to determine a pack's suitability for a brushless application. Recommended battery capacity for 1:8th scale vehicles is 5000mAh. We recommend using 30C continuous discharge or higher LiPo batteries (or high quality 25C batteries such as Traxxas® Power Cell).
  2. Our experience  suggests using only mild gear ratios with NiMH cells. Do not attempt to use NiMH cells in extreme setups.
  3. Applying voltages higher than 25.2V will cause irreparable damage to ESC.
  4. We recommend a high-current connector designed for high-powered electric systems, rated for 70+ amps. Invest in connector sets made for high-powered electric systems such as our CCBULLET 6.5mm, Castle 6.5mm Polarized Connectors, Traxxas® Power Connectors, FlightPower Star™ Plug, or Deans® Ultra Plugs

Product Features
Date Logging:
Mamba Monster X can capture and record performance data from your last couple of runs, commonly referred to as data logging. This data 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 Functionality:
Mamba Monster X features the addition of a new, programmable AUX wire that allows you to make “on-the-go” adjustments to several settings such as torque control, and max throttle, and fine-tune the performance of your ESC right from the transmitter using an auxiliary channel on the receiver. The AUX wire function is disabled by default but is programmable via Castle Link or the Castle Link iOS App. Once you have programmed the functionality of the AUX wire, that setting can then be adjusted on-the-go from a compatible transmitter. Click here for additional information.
Fully programmable Castle feature set using Castle Link USB adapter (coupon for free Castle Link adapter included in package) and freely downloadable Castle Link Windows software or the Castle Link iOS App and a B-LINK Bluetooth Adapter.  (A small subset of the settings available through Castle Link Windows software can be accessed via manual programming through the transmitter stick).
Firmware Updates:
Users will receive free access to all firmware updates, including added features sets using the Castle Link USB Programming Kit. Click here for software versions available for Mamba Monster X.
Power System Alerts:
Mamba Monster X also features updated Audible Alerts that will notify you of possible issues with calibrations and error conditions to help diagnose problems in the field. Click here to see complete list.
Telemetry Capable:
Mamba Monster X is telemetry ready, which means owners of Futaba T4PX Transmitters will be able to purchase the Castle Creations Telemetry Link for S.BUS2. Real-time data such as ESC temperature, voltages, and RPM can be monitored to ensure performance advantages and spare you the “unknown” parameters that all R/C enthusiasts experience at some point. Telemetry data provides another level of protection and can increase performance.

Well designed ESC
February 25, 2017
I waited a long time to get a sensored ESC from Castle but reliability issues with other vendors pushed me to try the Monster X. It is a very compact unit that fit well into My Tekno EB48.3. It's an 8th scale buggy but there isn't much room for electronics. One of the features that allowed this ESC to fit is that all the wires come out the top of the ESC. I had trouble with other systems that had the receiver lead or on/off switch lead protruding from the side of the ESC because the limited space caused the wires to wear against the chassis or other components in the buggy while taking jumps and racing incidents. This caused DNFs and in some cases irreparable damage to the ESC. Not a problem with the Monster, just get a new low cost harness and swap it out in less time than it would take to heat up your soldering iron.
The BEC is also a great improvement. With some of the other ESCs I have used, I needed an external capacitor or BEC to handle the high torque servos required for 8th scale racing; The Monster handles it without a glitch!
Other features like the Aux line that I use to turn on/off reverse with the touch of a button on my radio makes it easy to turn off reverse when racing. And data logging, Castle link and all the other things that are built into this ESC make it a winner in my book. In fact the only negative I have found with this ESC is that the label on the bottom of the case is too slick to use double sided tape to hold the ESC to the mounting tray in my buggy. I tried a number of types of tape and none of them worked. No matter what I tried the ESC would come lose. Finally a friend of mine suggested using "Shoe Goo" and that did the trick. I think Castle should and this suggestion to the manual.
If you haven't tried this ESC you owe it to yourself to give it a shot.
