Castle Creations Releases New Monster X Speed Control

Castle Creations Releases New Monster X Speed Control

The Monster  X is the latest in the Monster line from Castle Creations and it’s designed to operate big power vehicles such as 1/8-scale buggies and truggies, on-road cars and monster trucks. The Monster X speed control is packed full of features such as the ability to adjust one of many settings from an aux channel on your radio and it’s telemetry ready for those who are using a Futaba 4PX radio. Other features include data logging, an improved BEC and it can operate sensored motors. You can buy the speed control by itself or with one of Castle’s 2200Kv or 2650Kv brushless motors in a combo.

See full details from Castle below.

From Castle:

Meet the Next Monster.

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.

Extreme Power • Extreme Control • Extreme Fun!

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.

Sensored Motor Capable

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.”

Extreme Power

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.

Monster X Data Logging

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.

Telemetry Ready (Futaba T4PX Transmitters only)

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 (available late July 2015). 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 do – burn rubber and throw dirt!

Extreme ESC and Extreme Combos

The Mamba Monster X is available as an ESC only or in combination with Castle’s award-winning 15XX Series brushless motors; the 1515 2200KV or the 1512 2650KV motor.

Input Voltage Range: MIN: 2S LiPo; MAX: 6S LiPo (25.2V)

BEC Specifications: Adjustable: 5.5V, 6.0V, 7.5V. or 8.0V (8A Peak), default 5.5V

Operating Environment: Waterproof* design allows for use in nearly any environment. (See Product Use Statements)*

Brake: Proportional

Reversible: Yes – with lockout

On/Off Switch: Yes

ESC Cooling Fan: Yes, factory equipped (30mm), fully removable and replaceable. (See Product Use Statements)**

Size: 5.3cm x 4.9cm

Weight (w/wires): 111.1 g

Items Needed for Operation: Battery Connector required, Castle 6.5mm 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.


Part Number: 010-0145-01


Input Voltage Range: 2S-6S LIPO (25.2V MAX)

Motor Size: 39.98mm X 75.18 mm

Motor Weight: 15 oz. (424 g)

Max Vehicle Weight: 15lbs. (6.8kg)

Mounting Hole Specifications: 3mm @ 25mm

Shaft Diameter: 5mm

Max RPM: 60,000

Weight (w/o battery connector soldered to ESC):  

Application Guidelines:  The ESC and motor are intended for up to 6S (25.2 Volt) operation. Incredible in monster trucks with up to 6S LiPo packs (4S LiPo is the sweet spot), and works great in 1/8th buggies and truggies and on road as well. (vehicle weight limit is 15 lbs or less, with batteries ready-to-run). 

Tech Notes: The Castle 1515-2200Kv motor is 75mm long making it capable of handling more power and heavier vehicles than the Castle 1512-2650 motor.

**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: Not all LiPos are created equal, and surge ratings should never be used to determine a pack’s suitability for a brushless application. Use the CONTINUOUS C rating only. Mamba Monster setups frequently hit 100+ amps in peaks. We strongly suggest using 5,000 mAh or larger LiPo cells with a discharge rating of at least 30C (or high quality 25C batteries such as Traxxas® Power Cells®). Our experience suggests using only mild gear ratios with NiMH cells. Do not attempt to use NiMH cells in extreme setups.
