We are excited to provide the next generation of brushless power for 1:14th and 1/16th racers and off-road fans, as well as the scale community. The MAMBA MICRO X2 takes full advantage of the improvements in Castle's software technology and thermal cooling capabilities with the addition of CRYO-DRIVE as well as a sleek new lightweight/heat conducting, anodized aluminum case. These improvements mean the Micro X2 can gear more aggressively, for more speed and harder/longer runs, at a higher input voltage! Also new to the Micro X2 is the addition of data logging. Users will be able to record real-time data such as motor RPM, battery ripple, ESC and motor temperature, throttle input, and more. Performance data from Data Logging allows users to make setup adjustments to maximize both performance and battery life. Mamba Micro X2 still sports the programmable Auxiliary Wire that allows users to make “on-the-go” adjustments to several settings such as torque control, and max throttle, and fine-tune the performance of the ESC right from their transmitter! The Rock Race/Crawler Mode has incredible versatility and is a fan favorite for the crawling community. The Mamba Micro X2 ESC is ready to run out of the box. They may also be “tuned” for the drivers' preferences in the throttle curve, brake strength, reversing and reverse lock out modes, and more. Accessing these features is easy with the free Castle Link USB Adapter (coupon enclosed in box) and Castle's simple programming interface on a Windows PC. There is also convenient transmitter programming for six common adjustable settings or optional smartphone-based programming with the B-LINK Bluetooth Adapter (sold separately) and the free Castle Link app on Google Play or Apple App Store. Don't be fooled by the Mamba Micro X2 tiny footprint, this mighty mini has plenty of muscle and can handle power hungry applications with ease!
