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 aluminum 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-anodized aluminum towers. Multi-split-spoke wheels come outfitted with super-aggressive, multi-surface dBoots® COPPERHEAD 2™ tires. 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 anodized aluminum chassis as the foundation for the KRATON™ 6S BLX 4WD. A center body support, aluminum 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" aluminum 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.

Frequently Asked Questions
This is your answer.
I'm new here in Pensacola and I called around to a few places to find certain things for my car. And ended up here at kings. I was amazing by the amount of product they car. And the young man behind the counter was so helpful and polite. Me and my sone got what we need and found a few other great info that we really needed.
Thank y'all so much
I live in Texas and have used King's website for a few purchases now, and every time they make sure to get my order shipped as fast as possible. Every order I have received has been packed perfectly and securely. I highly recommend them!
Great experience! They had a rare item in stock. Packaged very well and shipped promptly. I will definitely order from them again.
I’ve ordered online and now I’ve been in person. Stellar service and very knowledgeable. Corey and the guys know and love what they do. I’ll be back next year for sure!
Great Products - got my RC Porsche from them - through their ebay store - fast shipment - well packed - great service. Very happy with purchase from King Cobra!
When into the shop on a whim with my son because I’ve been wanting to get back into RC cars. We ended up walking out with an Arrma Granite Mega by recommendation of Corey. He was a great help and answered all my questions. They only thing I was dissatisfied with was I asked about the run and charge time on the battery and was told about 20-30 minutes run time depending with about an hour to recharge the battery. The recharge time for the battery is about 3.5 hours with the charger that comes with the kit. The truck is a lot of fun, great to learn on and plenty fast for my 4 year old. I would recommend immediately buying another battery or upgrading to a LiPO battery and better charger.
I purchased an Axial SCX24 online. It was a quick and easy process, quick shipping, and the only place I could find with the one I wanted in stock! I'll definitely be using them again!
I have had such a wonderful experience with these guys. Over the last few weeks I have ordered an extremely large amount of product from them and I have been taken care of on each question I've asked and each concern that I've had. The real standout of the team so far, is Amanda (Mandie). I have been on the phone with her multiple times over the last few days because of a few little questions that I've had and she has gone above and beyond to help me every single time. I feel like this is a relationship that I will have with this company for a long time and look forward to doing business with them in the future.
These days, it's hard to find customer based businesses that take things seriously and these guys have it for sure. Excellent place and very trustworthy!
Great place!! My husband and I go there almost weekly, the staff is also very helpful. If you want a family feel atmosphere where they know you by name and always very helpful swing in and say hi you won’t regret it.
