The Mamba Micro X2 is a refresh of our popular 1:18 scale Mamba Micro X. This new ESC increases the maximum input voltage to 4s. We also added DATA LOGGING and our CRYO-DRIVE™ TECHNOLOGY; CryoDrive allows the ESC to run cooler and more efficiently at partial throttle.  Like its predecessor, it is waterproof* and has SENSORED MOTOR SUPPORT. This is the perfect upgrade for 1:18th scale 2WD or 4WD vehicles up to 2.25 lbs. The Mamba Micro X also works well in some 1:10th scale crawlers for low speed operation (no rock racing/hill climbing). You can now purchase the Mamba Micro X2 Crawler Edition ESC paired with our Slate Crawler motors.

Important Product Update, 6/14/2023.
The internal BEC is back! All Micro X2s made on or after June 2023 will again have the internal BEC. You can check the date of manufacture on the side of the ESC box or on the ESCs receiver wire. ESCs made between August 2022 and May 2023 do not have an internal BEC and include an external 10-amp CC BEC; click here for more information.

*Although the Mamba Micro X2 is waterproof, it is 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 with clean water after exposure to corrosives or dirt. While the 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.
