The Castle Creations Mamba X is going to shake things up. Extremely versatile, and capable of powering a wide variety of applications and vehicles* the Mamba X is ideal for racing at the track with your 2wd buggy, bashing through mud puddles in your monster truck, or navigating a hardcore trail with your crawler. The Mamba X raises the bar.

ESCs have a tough life, huge jumps, accidental collisions, and splashing through puddles. Castle engineers understand this and designed the Mamba X to endure these situations and power through them. It is housed in a rugged CNC-machined aluminum case and then potted in waterproof epoxy. This not only protects the electronics but ensures any heat generated in the controller can easily be dissipated through the case.

The high performance Mamba X includes an integrated and powerful 8A adjustable BEC and can push the most extreme 1/10th scale setups and 1/8th scale* race buggies. SmartSense allows you to take advantage of smooth, cog-free, and predictable sensored starts, and Castle’s new and improved throttle response keeps you ahead of the competition.

*In 1/8th scale setups, the Mamba X is intended to be used for off-road racing in buggies weighing up to 9 lbs (including batteries and ready-to-run). In these 1/8th scale racing setups, the Mamba X should be run at 4S Lipo (16.8V) max and is recommended to be paired with the Castle 1512-1800Kv (P/N: 060-0062-00) or Castle 1512-2650Kv (P/N: 060-0061-00) motor, with appropriate gearing only.

In Depth Features:

  • SMARTSENSE™: Enabled by default, the Mamba X uses the motor’s sensors to provide smooth starts, excellent torque, and low-speed drivability. Once the motor is turning, it seamlessly transitions to Castle’s ULTRA-EFFICIENT sensorless mode with electronic timing. When running, a motor must transition between different load points and a different timing advance is required for optimal efficiency at each. Electronic timing in SMARTSENSE™ will advance timing automatically for peak performance during all driving conditions. This combines the best of both worlds in an unrivaled HYBRID between smooth sensored startups and high-efficiency sensorless running. Your motor will produce more power and less heat.
  • AUXILIARY WIRE FUNCTIONALITY: The Mamba X allows “on-the-fly” adjustments to be made through the AUX wire once enabled in Castle Link. Once you have selected an AUX wire function, that setting can then be tuned from your transmitter while driving. Torque control, max throttle, max brake and drag brake adjustments are a sampling of the available modes. This real-time tuning allows you to quickly and easily fine-tune your system.
  • DATALOGGING: Enabled by default, the Mamba X captures and records performance data from your vehicle. This allows you to view a detailed turn-by-turn record of what your ESC actually experienced during the run. You will be able to record real-time data such as motor RPM, battery current and voltage, ESC and motor temperature, throttle input, and more. Download and analyze the collected data via Castle Link and make adjustments to maximize both performance and battery life.
  • CASTLE LINK™: For nearly 20 years Castle engineers have been setting the bar for industry leading software functionality. The Castle Link Programming Suite is your ticket to creating the perfect setup. To gain access to the host of tuning parameters, simply redeem the coupon for the Castle Link adapter included with your Mamba X purchase. Download the simple to install software from the Castle website and you are ready to personalize your controller’s parameters. Don’t forget to use the “check for updates” feature in Castle Link to download the latest software as it becomes available. New features are yours at no cost, a perk for choosing Castle.

Product Use Statements:

  • *Although Mamba X is waterproof, it is not intended for operation while completely submerged in liquid. Always rinse the ESC and motor with clean water after exposure to corrosives or dirt. While the motor and controller may be waterproof, Castle suggests 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.

Tech Notes:

  • Mamba 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 1:10th and 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).
  • Our experience suggests using only mild gear ratios with NiMH cells. Do not attempt to use NiMH cells in extreme setups.
  • Applying voltages higher than 25.2V will cause irreparable damage to ESC.
  • 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 Castle 6.5mm Polarized Connectors, Castle 4.0mm Polarized Connectors, Traxxas® Power Connectors, or Deans® Ultra Plugs

Castle Creations Mamba X Waterproof 1/10 Scale Brushless ESC
I use these in my shortcourse trucks and have had good luck. I buy the combo's for under 200.00. Have a couple with the 1410 3800kv and one with the 1406 4700kv. Very smooth throttle with sensor connected and tons of power. Using castle link they are highly adjustable. I've only run them with 2s so can't comment on higher voltages. Fan is temp controlled and only comes on when the esc gets pretty warm. Price for buying esc by itself seems high when you can get it with motor for about 45 bucks more. My only wish is castle link would allow you to run the fan in always on mode. Have had a twig get in the fan once that stopped the fan from starting once it got hot. Love the combo with the 1410 3800kv. Plenty of power and doesn't get hot. The 4700kv motor is great but even geared way down you have to keep a close eye on temps.

Castle Creations Mamba X Waterproof 1/10 Scale Brushless ESC
Excellent and user friendly ESC. Adjustable drag brake, Blue Tooth a sold BEC as well as other adjustable options make this an excellent ESC. It is a little larger than a HW but easier to use/understand in my opinion. Very happy with this ESC so far, highly recommended.

Horrible product, burned out very quickly. BEC works for a little, but then stops working. Switched over to tekin's RX4 at axialfest, and couldn't be happier.
