The Mamba Micro X2 is a refresh of Castle's popular 1:18 scale Mamba Micro X. This new ESC increases the maximum input voltage to 4s. Castle also added DATA LOGGING and CRYO-DRIVE™ TECHNOLOGY; CryoDrive allows the ESC to run cooler and more efficiently at partial throttle. Like its predecessor, it boasts an 2 amp peak BEC, 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 Castle's Slate Crawler motors.
