• 2S - to - 6S Capable
• Sensored and Sensorless Motor Capable
• Monster X Data Logging and Telemetry Ready

First, there was the Monster. Then the Monster 2. Now there’s the Monster X. As revolutionary as it’s predecessors, the new Monster X Electronic Speed Controller (ESC) takes Castle’s legendary “monster” performance to a whole new level. The waterproof* Monster X is capable of 2S LiPo up to a maximum of 6S LiPo and is the legendary “power up” for 1/8th scale buggies, truggies and on-road vehicles as well as 1/10th scale monster trucks and R/C monstrosities weighing up to 15 lbs.

The new Monster X provides even more extreme performance than the Monster 2. Most notable is the addition of a new, programmable Auxiliary Wire that allows users to make “on-the-go” adjustments to several settings, such as torque control and max throttle. The new Auxiliary Wire allows users to fine-tune the performance of their Monster X 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. Once the user has programmed the functionality of the AUX wire, that setting can then be adjusted on-the-go from a compatible transmitter. 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 new Monster X can also be configured to run sensored brushless motors with the purchase of an optional Sensor Harness from Castle Creations. This sensored-motor capability opens up a whole new segment of R/C enthusiasts who will now get to experience (or see the rooster tails) from a Castle Monster X-equipped racer, rock racer or rock crawler. One of our Monster X Beta testers summed up his experience, saying “Another race weekend in the books. Once again, in sensored mode, the ESC (Monster X) performed flawlessly. Great power and smooth transition from sensored to non-sensored.”

The new Monster X is capable of running from 2S to a maximum of 6S LiPo power, but now features an improved heavy-duty adjustable Battery Eliminator Circuit (BEC) to provide plenty of power for today’s power hungry servos. The Monster X BEC voltage is adjustable from 5.5V, 6.0V, 7.5V and 8.0V while output is rated at 4.5 AMP continuous and 8 AMP peak. The Monster X also comes standard with a highly efficient, 30mm ESC cooling fan.

Also new to the Monster X is the ability to capture and record performance data from your last couple of runs, commonly referred to as data logging. This data can be downloaded via the upcoming Castle Quick Connect Duo (sold separately) that allows the user access to both wires into the single Castle Link connection. The user can then analyze this data and make adjustments to the ESC to maximize both performance and battery life.

The new Monster X is telemetry ready, which means owners of Futaba T4PX Transmitters will be able to purchase the Castle Creations S.BUS Telemetry Link when it is released. 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, can increase your “tuning awareness” and in turn, let you have more time doing what you love to
