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.
