ARRMA® engineers have outfitted the KRATON 6S BLX 4WD with a brushless power system that now features the Spektrum Firma 150A Smart ESC and Firma 2050Kv brushless motor. The combination delivers incredible torque, acceleration and speed.


For improved steering, ARRMA® also includes a new, steel gear Spektrum S652 Digital Servo which is 32% stronger and 5% faster than the previous version's ADS-15M servo. Add your favorite 4S or 6S LiPo battery and watch this monster truck smash your speed expectations — up to 60+ MPH in optimum conditions with a 6S LiPo battery and the included optional speed pinion gear.


The ready-to-run package now also includes a 3-channel Spektrum SLT3 radio and Spektrum SR315 dual protocol receiver. If you're a new driver, you'll be able to set throttle limits at 50% or 75% until you're ready to use the full speed potential. The SLT3 is compatible with Tactic® SLT receivers to run other RTR vehicles you may own, and includes a third channel to control optional features such as lights and winches on models that have them. Because the SR315 receiver can use SLT and DSMR® protocols, you can easily upgrade to a Spektrum DSMR® transmitter later — then, download the free Spektrum Dashboard app for your mobile device and take full advantage of the Smart telemetry capabilities already present in the Firma electronics. You'll be able to receive real-time updates of ESC temperature, receiver (BEC) voltage, drive pack voltage and motor RPM.
