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

NOTE: Water Resistant Motor 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 recommends 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 the document in the resources tab for running and maintaining motors in wet environments.

Castle Creations Mamba X Waterproof Sensored Brushless Combo w/2850kV Slate
Best purchase so far for my axial bomber build. The install of this combo is very easy to follow and programming was simple too. The only thing i wish was that they factory installed the battery plug, only because some of us do not have much experience in soldering. Other than that, i am extremely happy with this motor and ESC combo.

Great system. The Castle programming options are second to none. The slate motor works great in crawlers and gives plenty of wheel speed

Castle Creations Mamba X Waterproof Sensored Brushless Combo w/2850kV Slate
I’ve been running this system for over a year now in my scx10. Countless 2s and 3s packs have been through this system. I have never had a single failure. It’s the perfect balance of speed, control ability and value. I plan on using this system in any other scaler I build. I’ve had it submerged multiple times during creek crossings and the only failure was the on and off switch (but that was my fault, they aren’t designed to be submerged). I wired the switch closed and haven’t had an issue sense. This system on 2s should be plenty for anyone who likes fun running. For mudding 2s is more than capable but if you really want that tire speed run 3s. Doing either of these things I have never had an issue with over heating issues. Highly recommend this system.

Castle Creations Mamba X Waterproof Sensored Brushless Combo w/2850kV Slate
This setup is worth every penny. I'm running it in an rc4wd gelande 2 chassis with 9/64 gearing and the balance between wheel speed and torque is incredible. All the finesse you could ask for and mass amounts of horsepower on tap when you need it. The only downside is that the esc is physically huge and could limit interior choices if you dont have much spare room to work with. I've got a solid 20 hours of crawl time on mine and it's never even broke a sweat.

Castle Creations Mamba X Waterproof Sensored Brushless Combo w/2850kV Slate
This is not a review so much of the product, but of Amain. I ordered this item early in December. When I purchased this I was told they would be sent at the end of December. It’s nearly been 2 months now, and I still have nothing. Now whenever I contact them about my order they say “ we don’t know when we will receive this item.” How do you know know anything?! Pretty mad. This is not the first time I have been upset with Amain.
