Review: Fun monster truck - High quality RC car for a good price. There is a big difference between this and what you get for around 200 or less. I like the wide wheel base and mostly drive in grass I’m using a 2S battery so it will be easier on the gears and it goes plenty fast for me. 3s will get this thing going really fast Be aware battery uses EC5 plugs so my batteries for my other cars didn’t fit. Also the wheels can fall off if you don’t tighten a certain screw, so go on YouTube and figure that out first or after a wheel falls off, happened to me first time driving it is a very easy fix and nothing is broken.
Review: Near indestructible - Perhaps I'm lucky, but I have a ton of RC cars (3 are Arrma), and this guy is by far the most robust one. I did change out the stock servo with a 35kg one, but I went through about a dozen batteries before I finally stripped a gear. This is not the fault of the product at all. If you're going to run these guys hard you will break parts! What I love about this is just how tough it is. I changed my ESC to punch setting 5 and haven't looked back. I did all of these mods over a short period of time, if anyone else is interested: - swapped out the servo (everyone says this is a must) - swapped out the rear diff with a metal one (you could probably get away with just the input gear to metal) - swapped rear diff housing (yoke) with an aluminum one - added an m2c chassis brace to the bottom, - replaced all shocks with typhon 6s shocks (moved the stock big rock shocks to my son's vorteks, perfect upgrade for both cars) Other things I plan on doing very soon - diff fluids in both front and rear to probably 30-50k front and 15-20k rear - aluminum pivot balls - front diff input to metal And eventually - swap slipper clutch with a center diff (only when it dies) - swap from 3s to 4s esc/motor (probably waiting for it to die, if it ever does) Honestly love this thing even on 3s. It's so damn fun! I also have a notorious 6s and my son (as mentioned) has a 3s vorteks. The vorteks actually can flip about 30-40% faster in the air than the big rock on punch 5, but I find the big rock much more robust. The other great thing about the big rock is on its stock arms it drives pretty well on grass, whereas the vorteks is better on flat ground. If you're picking this up, be prepared to learn a lot. Watch youtube videos, go on the forums, go on the facebook groups. There's a ton of help out there!

## Questions & Answers

**Q: Will the 26 tooth pinion gear for my arrma typhon 3s blx fit my arrma big rock crew cab?**
A: Yes it will

**Q: What is the hex size?**
A: OTB is 14mm..I'd suggest buying Typhon Axles, and hubs, and RPM Front & Rear suspension arms to get 17mm Hex. But at that point, you almost at the price point of the Typhon 6S, and being honest a way better car. Typhon 6S was rated #7 of top 10 RC of 2021. That says alot considering some upper models are $900+

**Q: Que clase de batería y cargador necesita**
A: This truck takes a 2 or 3 cell LiPo battery, models: SPMX50003S50H5, SPMX50003S100H5, SPMX50002S50H5 and Spektrum Smart charger models: S2100, S150, S1100.
Thanks for asking.

**Q: Tiene control el carro**
A: Si tiene

### ⭐⭐⭐⭐⭐ The Arrma Big Rock RC truck is a solid 9/10. Infact, this thing is epic!
*by D***I on May 10, 2023*

I started my journey into the RC car world approximately 2 weeks ago. I first purchased a Haiboxing 1/12 scale 903a (which was great but a little small and the gear/differentials made an awful racket at certain speeds and the shocks which were supposed to be oil filled weren't; I bought another one to see if it was any better and the shocks were filled this time but the drivetrain made an even worse racket). Both ended up getting returned. The second RC car purchased was a Hosim 1/10 scale X08 which was much better overall when compared to the Haiboxing, and I would have kept it, if it wasn't for what is a "drag brake" problem that made the car difficult to drive when letting off the gas (it would almost flip over itself due to the strong braking at times or flip on the side with turning and letting off). I looked it up on youtube and RC Guy Garage also complained about this and he hated it. I returned the Hosim after running it for 15 minutes and finding out that this isn't an isolated problem. Lots of background info here, I know I know, bear with me. Now onto the Arrma Big Rock. THIS. THING. ROCKS. I haven't had this much fun with something like this in years. It has quickly become almost an obsession. I have always had many interests (cars, computers, electronics, DJ'ing) but nothing has ever, with the exception of maybe DJing, had me so infatuated. I guess this is what a true hobby feels like? I think so. As far as the car itself: The car is fast (almost too fast on 3S, especially after calibrating the throttle, make sure to do this as it wasn't done out of the box, now even on 50% on a 3S battery it scoots and honestly is plenty fast on the streets and small parking lots, 75% is borderline too quick, and 100% is basically only for straight line runs, at least for me!). 2S batteries come tomorrow (which were recommended as opposed to 3S by my buddy who has worked at Hobby Town for 20+ years but I didn't listen and purchased 3S initially). The car is tough, I have hit curbs and big rocks, with a few of these crashes resulting in the car flying 5 feet up in the air or doing cartwheels for 30 feet and other than some scrapes everything is running strong (only about 10 hours on this thing though so as far as longevity of components I cannot give a good impression). The car looks good, proportions are right, the wide stance is great, and the all-black crew cab fits the longer wheelbase very well. I think LED headlights or a bumper light bar would be awesome but I am sure that can be installed. I have also had multiple people approach me around my neighborhood and the random parking lots and parks I've been to and ask what it is and where I bought it and of course I happily oblige with the information they request. One of my neighbors went home and bought one same day after seeing me drive it around (a different Arrma but goes to show how excited people get when they see this thing). Overall this car is a 9/10. Oh, and I have an Arrma Kraton 1/10 coming tomorrow... It has begun... Cheers!
