The Mamba micro x puts extreme power, extreme control and extreme fun in a relatively small footprint – small enough for most 1:18th scale vehicles. The waterproof micro x is suitable for 2WD or 4WD vehicles over 1.5 lbs and up to 2.25 lbs. In following with the other Mamba x series ESC, the new Mamba micro x features even more extreme performance and capabilities than the 010-0147-00 it Replaces. The new micro x receives a heavy-duty beck (battery eliminator circuit) to handle today’s high-draw digital servos and also features a programmable auxiliary Wire (aux) that allows the user to make “on-the-go” adjustments to several settings, such as torque control and Max throttle, directly from a compatible transmitter. This allows you to fine-tune the performance of the micro x to meet changing driving conditions. New to the micro x is the ability to run censored brushless motors with the purchase of an optional sensor harness from Castle Creations. Now, a whole new group of R/C enthusiasts will be able to enjoy the power, control and fun of a castle power system in your vehicle.
