Castle Creations Monster X Brushless ESC with 1515-2650kv Sensored Motor, 010-0145-06

In stock

The Mamba Monster X ESC and 1515-2200Kv V2 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.

Product Information

Castle's commitment to excellence drives them to refine the user experience, optimize performance, and ensure that every aspect of their products are meticulously designed to provide the utmost satisfaction. Let's face it, even the best products have room for refinement, which is why they are introducing 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!

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.


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.

1515-2200Kv V2 Motor

The 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.

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.
