Matthew Tayloron Arrma Kraton 8S BLX EXB Brushless RTR 1/5 4WD Monster Truck (Black)

To start out, this isn’t my first 8S Kraton. I had a V1 Kraton, and owning it was a miserable experience for me. Seemed like every time I took it out I bent or broke something. I was very hesitant on buying the V2 for that reason. I’m so glad I didn’t listen to my gut. I forgot just how much fun it is to drive one of these. When my V1 ran, I absolutely loved it. Handled incredibly well, jumped level, and was in a class all by itself when it came to sheer performance on this scale. This truck is very much the same, and then some. Here are some of my observations on the first run of this beast. Performance: It jumped high and air control is effortless. It actually outperformed my XRT in this aspect by an impressive margin. It cornered like it’s on rails, and not one single traction roll out of it. The speed is actually comparable to my V1 with the 800kv Castle combo I had in it. The new motor and ESC are on point. I have zero plans to upgrade them, which for me, is very odd. The torque comes on very strong, and the throttle response is immediate, and I did not turn up the punch at all. I did turn up the brakes from the factory 25% to 50%. Steering: The new servo is a massive improvement over the V1 factory servo. It’s somewhat quick, it’s a full 1/5 scale size, it has loads of torque, and runs on 8.4v right out of the box. As a matter of fact, the ESC factory setting is 8.4v. What lets the steering down, as was with my V1, is the servo saver. It does ok, but needs to be a bit stiffer. The servo returns to center well, but the servo saver does not, so there’s a lot of correction to be done while steering. It’s not a dealbreaker, but I’m going to be looking for a better alternative. Motor/ESC: I have nothing negative to say about this combo. It’s astounding how well Arrma did with this. The ESC is extremely nice in the way it programs, since my Spektrum program box isn’t yet comparable with it. More on that later. The motor is head and shoulders above the old one. I couldn’t replace that one fast enough. I will probably never replace this setup. It’s that good. Power is immediate and very smooth. Very impressed. Programming: I plugged my Spektrum V2 programming box into the ESC and it gave the message “please update firmware”. That’s no biggie, out comes the laptop, downloaded the latest spectrum app, and as it turns out, my version of firmware is the latest version. So I guess they haven’t released the newest version of the firmware for the program box. Bummer. But it’s all good, it’s a cakewalk to edit settings just using the buttons on the ESC itself. Telemetry: I use a DX5 Pro radio, so after binding it with the stock Spektrum receiver, I found that this setup has an insane amount of telemetry data on the radio. I can check temps, read motor RPM, battery level, and a ton of other stuff. It’s awesome. Battery Life: Let’s face it. It’s a 30+lb. Truck with a huge motor. Comparatively, battery life will be abysmal. I got about 20 mins of hard running out of a pair of Spektrum G2 6800mah Basher series batteries. About 10 mins shy of what I get out of my XRT with the same batteries. I already expected this, because my 800kv Castle V1 was about the same. It really doesn’t bother me at all, because I usually have a couple trucks charged up and ready to run when I go out to bash, so it’s just not that big of a deal. That’s the price you pay for this level of performance. Durability: The elephant in the room. How did the truck hold up? As I mentioned, that was the Achilles heel of the V1, at least in my experience. The simple answer is that it did not have a single issue! First off, I was not being gentle on this thing. I was jumping pretty high, back flipping, I cartwheeled it, I landed a particularly high jump directly onto the wing, which consequently acted as a shovel and dug a chunk of dirt out of the ground almost 2” deep lol. I lawn-darted it trying to do a front flip, and I did beat it pretty hard. Absolutely nothing broke. There’s no way they didn’t change something about these A-arms. They took some direct hard impacts with zero problems. This thing is an absolute beast of a truck! The Verdict? This may just be my new favorite truck. Other than a better servo saver, I have zero upgrade plans. I’m actually happy with it as-is. And that feels icky.

Awesome truck!!!! I’m really glad I finally got it,couldn’t be happier. Took it out on the first spin with my son and it’s definitely money well spent!

Eric JohnsonVerified owneron Arrma Kraton 8S BLX EXB Brushless RTR 1/5 4WD Monster Truck (Black)

Really amazing rc vehicle, very large and very powerful. Requires a great deal of self control with the throttle. The right batteries are crucial as this needs a lot of juice. I have fixed 2 broken suspension arms, one front and one back but honestly this was probably due to my inability to modulate the throttle properly. You really can’t pin it for more than a very brief few seconds unless you have a huge area free of obstacles. Just a complete animal, throws dirt and rocks, leaves trenches in the grass and smells like a rototiller from the churned soil. Again can’t stress the fact that it’s big and fast. Wheelies happen very quickly and this can affect directional control significantly. I am glad I bought it, it’s pretty easy to work on due to the size. Might be slightly overpowered but that’s why we like em. It vaults into the air easily and flys well, but I would try to avoid anything over 3 or 4 feet mainly due to the heft. Again large open areas are required and it is extremely powerful and fast.

What reviewers say

Reviewers largely rate the Arrma Kraton 8S BLX EXB highly, praising its power, speed, jumping ability and handling, with several noting it is a strong bash truck. Many describe it as big and heavy, and some say it demands careful throttle control, since wheelies and loss of directional control occur quickly. Some owners report broken suspension arms or upper blockheads after rough use, and one reviewer reports defective parts out of the box that were replaced by the seller. One reviewer rated it 1/5, reporting that the truck would not program despite the fan running, and described it as defective; this is the only negative review. Several reviewers praise seller support and delivery. Most reviews are from verified owners.

  • + Strong power and speed
  • + Good jumping and handling
  • + Durable under abuse for some owners
  • + Responsive seller support
