The 2019 V4 Arrma Kraton is here - and it's more aggressive than ever...

The ARRMA® KRATON 6S BLX 4WD Speed Monster Truck reaches a mindblowing 60+ mph, driven by its 6S capable brushless power system and durable design. Now comes complete with the 2.4GHz Spektrum™ STX2® radio system, it's fully equipped for fast, all-terrain bashing!

To put so much incredible speed into the hands of intermediate-level bashers, ARRMA® has outfitted the new KRATON™ Speed Monster Truck with a potent 2050Kv brushless motor. It's paired with the BLX185 ESC, featuring 1C5™ connectors and compatible with standard EC5™ connectors. Bashing is a "go" even through mud and snow, thanks to waterproof electronics. Add your favorite 4S or 6S LiPo battery and watch this monster truck smash your speed expectations, especially when running with the optional recommended pinion gear.

With adjustable oil-filled shocks soaking up the bumps, the KRATON™ 6S BLX 4WD Speed Monster Truck blasts over dirt, asphalt, grass - all terrain and all conditions. The shocks are mounted on black-anodized aluminum towers. New, 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 contributes to confident control and responsive handling at thrilling high speeds.

For the durability needed to support intense brushless performance, ARRMA® uses a strong anodized aluminum chassis as the foundation. A center body support and new aluminum center brace plus 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 new "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 five bolts. Topping it all off is a monster truck body with streamlined good looks, featuring a red/black or blue/black trim and ultra-detailed decals.

The ready-to-run KRATON 6S BLX 4WD Speed Monster Truck includes the new Spektrum 2.4GHz STX2® transmitter and comes with its SRX200 receiver and ADS-15M metal-geared servo already factory-installed. The only required items are a 4S or 6S LiPo battery, compatible charger, safe charging bag, and 4 x AA transmitter batteries. ARRMA® recommends the Dynamite® Powerstage™ Stage 6 bundle (DYN1540), which includes a Passport™ Ultra P2 100W AC/DC Multi-Charger and two Reaction HD 5000mAh 3S hardcase LiPo batteries with EC5™ connectors.

Arrma Kraton 6S BLX RTR 1/8 4WD Brushless Monster Truck (Red) (V4)
The Kraton 6s is a beast. I have had it about a month now and have driven it atleast 10 times. I have not been "extreme", but I beat the crap out of it bashing. So far only 4ft air jumps though. I have driven it on 4s and 6s and can say it is fun on both, but it is an animal on 6s. I have punch at 6 or 7 and stock gear, will flip over easily if you peg it at this punch on 6s. It is fast, not nimble like the Typhon, but it handles vey well. Still on stock everything except Tbone bumpers. Broke the front Tbone already. I also just broke a planetary gear (the bigger dished one) and the out drive pin on the same in the rear diff. The planetary gears seem to be a bit weak because of the recess for the pin, but they are cheap and easy enough to replace. I did not shim first so maybe slop, maybe bad landing or fluke. The radio does suck, but I can turn it down slow enough for my 6 year old to drive it while being unable to hurt it, even though he is able to tear it up at full speed on 4s pretty good already. He loves this thing as do I, but it's his lol, mine is the Notorious. I have broken a front and rear hub, shock rod ends, tie rod end and rear arm on the notorious but I slammed sideways into a curb at like 40 mph....twice lol. Going to try Teckno rod ends, and rpm arms. Maybe hot racing hubs. Planning on M2C goodies in the future. The Kraton rear shock tower is bent forward a bit as well from lots of bad landings. But like I said, we beat these pretty good. I bought them to bash and blast around like we stole em and that's what we do. I am planning to upgrade everything as it breaks until I can Rich Duperbash them. I am very impressed with the out of the box performance and durability. Just know that the weight and speed can and will break stuff if it gets away from you or you have a really bad crash. They are hands down the best rtr. They are tough, fast, and a blast to drive. Be ready to fix a few things if you want to really blast and bash though, but they are worth it. This is not a peice of garbage box store rc, nor is it a precision race machine. Designed purely for maximum fun and it sure does deliver. And I am seriously impressed with the abuse that it handles...if you "took care of it" and were even a little careful I doubt you'd ever break anything. Hope this helps someone looking at them.

Best truck I’ve ever owned, hands down! I’m glad Amain had it in red too. If you want something that’s fast and reliable, this is the perfect truck. Also Amain has a every part, if you ever decide to replace them. When paired with the Spektrum battery and charger bundle, this is a hit out the park!

This vehicle is a absolute beast on 6s out the box!!!!! Insane amount of torque and handles so well.... It can intimate you!!! I had a gear go bad withing 24 hours of using it and hobby town in Tyler Texas took care of me the following day with a new gear. This thing shreds however I did notice a slight lag in the controller... Gonna upgrade to a spectrum controller soon... This is worth the price go get it and you won't be disappointed Arma nailed this one!!

First brand new car purchase and first run dropped my jaw! This thing is quick and tough. I am new to this hobby and bought this for bashing. Can't wait for all the snow to melt so I can put it to the test. Well done!

Beautiful rc. Hate to get it dirty and scratched up. Had it for over a week and waited for some stuff before I unleash it.
