Putting the X in Extreme!

Our Mamba Monster X ESC  and 1515-2200Kv V2 are paired together and perform incredibly in monster trucks with up to 6S LiPo packs (4S LiPo is the sweet spot), and works great in 1:8 scale buggies, truggies and on-road vehicles as well as 1:10 scale monster trucks weighing up to 15 lbs. You will have all the power your 1:8th scale vehicle demands with the smoother throttle control of a sensored motor.  Mamba Monster X takes Castle’s legendary “monster” performance to a whole new level.

New 1515-2200Kv V2 motor now included!  Our commitment to excellence drives us to refine the user experience, optimize performance, and ensure that every aspect of our products are meticulously designed to provide the utmost satisfaction. Let's face it, even the best products have room for refinement, which is why we are excited to introduce the newly redesigned 1515-2200Kv V2, a new spin on one of the most popular motors we've ever produced! The transformation has included several improvements, most contributed by new stator and rotor assembly upgrades that, in turn, allow for even HIGHER EFFICIENCY, REDUCED TEMPERATURES, AND SMOOTHER START-UPS!

Note: 011-0130-00 Rotor Replacement is NOT compatible with the V2 motor. A new rotor replacement will be available in the future. Check back here for updates.

Weight (with no battery connector): 3.92 oz. (111.g)
Connectors: 6.5mm female bullets for motor connection.
Items Needed for Operation: Battery Connector required, 6.5mm Castle Connectors are recommended.
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.

**The cooling fan must be removed prior to driving in wet conditions. It is not waterproof.
Application Guidelines: Intended for up to 6S (25.2 Volt) operation in vehicles weighing less than 15 lbs, with batteries, ready-to-run.

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, or Deans® Ultra Plugs

Tech Notes:

Running modes: SMARTSENSE™, Sensored, and Sensorless 

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. Please refer to this document for running and maintaining motors in wet environments.

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.
1515-2200Kv V2 Motor:
Our IMPROVED 4-POLE 12-SLOT sensored design boasts exceptional EFFICIENCY and produces LESS HEAT
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.

    Got this as an upgrade in my 2.0 and let me tell you!! This thing rips! Running on 6s this thing will put a smile from ear to ear. It also brings all the neighborhood kids out and they watch with amazement as you send this thing down the street like a missile!
    All in all 10/10 for performance.
    10/10 for ease of use and installation.
