Mamba Monster X is the latest 1:8 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. Mamba Monster X also features updated Audible Alerts that will notify you of possible issues with calibrations and error conditions to help diagnose problems in the field. The Mamba Monster X is now paired with the new sensored 15xx series motors. Now you can have all of the torque and performance you know and love and have even more control! Castle uses the same high quality components as their sensorless motors, such as ultra-thin stator laminations, high temperature sintered neodymium magnet and high RPM ABEC3 bearings. Combo includes required Castle sensor harness and sensor wire for sensored operation.Mamba Monster X features the addition of a programmable Auxiliary Wire that allows you to make “on-the-go” adjustments to several settings such as torque control, and max throttle, and fine-tune the performance of your ESC right from the transmitter using an auxiliary channel on the receiver. The AUX wire function is disabled by default but is programmable via Castle Link (sold separately). Once you have programmed the functionality of the AUX wire, that setting can then be adjusted on-the-go from a compatible transmitter.Mamba Monster X can capture and record performance data from your last couple of runs, commonly referred to as data logging. This data can be downloaded via the Castle Link USB programmer; you can use the Quick Connect Duo (sold separately) to allow you to quickly access the ESC’s receiver wire without having to disconnect from your receiver. You can then analyze this data and make adjustments to the ESC to maximize both performance and battery life.Mamba Monster X is telemetry ready, which means owners of the Futaba T4PX Transmitters are able to purchase the Castle Telemetry Link for S.BUS2. Real-time data such as ESC temperature, voltages and RPM can be monitored to ensure performance advantages and spare you the “unknown” parameters that all R/C enthusiasts experience at some point. Telemetry data provides another level of protection and can increase performance.The 1515-2200kv version is capable of 2S to 6S LiPo and is perfect forMonster trucks up to 6S. This is the perfect motor for 1:8 scalebuggies, truggies and on-road vehicles as well as 1:10 scale monstertrucks weighing up to 15 lbs.
