The Mamba Micro X Crawler Edition Slate Combo is a great option for weight conscious, competition oriented crawlers and trail runners in vehicles weighing up to 8lbs on 2S or 3S. It can also be used in slightly more aggressive applications like rock racing and hill climbing on vehicles up to 4lbs. This SPECIAL EDITION combo features motor solder posts on the ESC with 16 AWG wire and 4mm female bullets for the motor connection that have been factory installed. The ESC will come with V2.02 firmware that has been enhanced for rock crawling and sensored operation. Castle "Slate" 1406 Sensored 4-Pole Brushless Crawler Motors are ROCK READY! With super smooth startup and low RPM control, Castle has you covered if you are looking for the ultimate motor for the trails or Ultra 4 track days. The 1900kv option is ideal for 1:10 scale low speed rock crawlers/trail runners on 2S-3S weighing up to 8lbs. NOTE: Use of an external BEC is required if running a high power or digital servo. If you're looking for a more aggressive setup in a heavier rig, like rock racing and extended hill climbing, Castle recommends the Mamba X ESC. ESC is only compatible with 2S-3S LiPo. Motor may be capable of handling higher voltage, but you must not exceed the max voltage range of the ESC. 8lb max vehicle weight when used for low speed/moderate driving style like rock crawling and trail running; 5lbs for more racing and aggressive driving styles. Features: The Auxiliary Advantage: Mamba Micro 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. Once you have programmed the functionality of the AUX wire, that setting can then be adjusted on-the-go from a compatible transmitter. Try out the brand new Crawler Mode for incredible versatility! Telemetry Capability: The Mamba Micro X is telemetry ready, which means owners of Futaba T4PX Transmitters will be 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.
