Extreme 1:8-Scale Waterproof Electronic Speed Control

The latest 1:8-scale monster truck controller from Castle Creations, the Mamba Monster X is capable of 2S–6S LiPo with an 8-amp peak BEC—plus, it’s waterproof, so you can run your vehicle through snowy yards, muddy trails, and morning dew. It’s a great upgrade for 1:8-scale buggies, truggies, and on-road vehicles, as well as 1:10-scale monster trucks weighing up to 15 pounds. It comes standard with a highly efficient 30-millimeter ESC cooling fan, and features updated audible alerts to notify you of any possible issues and help diagnose problems in the field. It’s paired with the company’s new sensored 15xx series motor, offering the ideal combination of torque, performance, and control. The programmable auxiliary wire lets you make on-the-go setting adjustments, while the data logging function captures and records data from your last couple of runs.

Note: This combo includes a 25.2V ESC and the sensored motor of your choice: 1800kv, 2200kv, or 2650kv. Quantities are limited to 12 units, 4 of each Kv Rating.

Product Use Notes

Although Mamba Monster X and Castle brushless motors are waterproof, they’re not intended for operation while completely submerged in liquid. They can corrode when exposed to corrosive materials, such as saltwater. Always rinse the ESC and motor with clean water after exposure to corrosives or dirt. While the motor and controller may be waterproof, the manufacturer 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.  

Technical Notes for the Controller

Mamba Monster X setups frequently hit 100-plus amps in peaks, and not all LiPos are created equal. Surge ratings shouldn’t be used to determine a pack's suitability for a brushless application. Recommended battery capacity for 1:8th scale vehicles is 5000 mAh. The manufacturer recommends using 30C continuous discharge or higher LiPo batteries (or high-quality 25C batteries like the Traxxas Power Cell). They also suggest using a high-current connector designed for high-powered electric systems. rated for 70+ amps, and using only mild gear ratios with NiMH cells. Applying voltages higher than 25.2V will cause irreparable damage to ESC.

Technical Notes for the Motor

Remove the dust cover from the back of the motor to connect the included sensor cable. If you’re running the motor sensorless, keep the dust cover in place. Motor wires can be shortened. Monitor motor temperatures closely, as overheating a motor will cause permanent damage to the magnets. Never exceed 180° F on the the motor or ESC.
