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. Heavy-duty aluminium and steel chassis and transmission components take it all in its stride. 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. Perfect for long hours of fatigue-free bashing, the transmitter's ergonomic design features a foam steering wheel for precise fingertip control and an improved hand grip and trigger feel. 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.

With adjustable oil-filled shocks soaking up the bumps, the KRATON  6S BLX 4WD Speed Monster Truck blasts over dirt, asphalt and grass - all terrain and all conditions. The shocks are mounted on black-anodised aluminium towers. Multi-split-spoke wheels come outfitted with super-aggressive, multi-surface dBoots  COPPERHEAD 2  tyres. A high downforce wing helps keep the vehicle grounded. Everything in the design contributes to confident control and responsive handling at high speeds.

For the durability needed to support intense brushless performance, ARRMA  uses a strengthened anodised aluminium chassis as the foundation for the KRATON  6S BLX 4WD. A center body support, aluminium center brace and composite chassis side pods add more strength. All-metal diff outdrives and gearbox internals, plus durable steel driveshafts, provide a reliable, heavy-duty drivetrain that holds up to extreme, high-speed bashing. A "never loose" aluminium steering servo saver and "never pop" ball ends supply more precision, reliability and confidence.

ARRMA  holds your maintenance downtime to the minimum with an efficient, driver-friendly design. A sliding mount allows quick, hassle-free motor access. The center diff is easy to reach and can be removed by taking out just seven bolts. Topping it all off is a monster truck body with streamlined good looks, featuring an eye-catching red/black or blue/black trim and detailed decals.
