The Mamba Monster X provides even more extreme performance than the Monster 2. Most notable is the addition of a new, programmable Auxiliary Wire that allows the user to make “on-the-go” adjustments to several settings, such as torque control and reverse enable or disable. This new Auxiliary Wire allows you to fine-tune the performance of your Monster X ESC right from your compatible transmitter using an auxiliary channel on your receiver. The Monster X also features updated Audible Alerts that will notify drivers of possible issues with their calibrations and error conditions to help diagnose problems in the field.  The ESC can also be configured to run sensored brushless motors in addition to sensorless and brushed. 

Mamba Monster X is a 1:8th scale and Monster truck controller capable of 2S - 6S LiPo, with an 8 amp peak BEC - and, it’s waterproof*, so you can run your vehicle through morning dew, across soggy snow, or a muddy trail. This is the perfect upgrade for 1:8 scale buggies, truggies and on-road vehicles as well as 1:10 scale monster trucks weighing up to 15 lbs.  It also comes standard with a highly efficient, 30mm ESC cooling fan.
