The Arrma Big Rock RC truck is a solid 9/10. Infact, this thing is epic!

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!

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 metalAnd 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!

Get ready to spend more money upgrading the internals

Go with the newer version ,this one comes with a plastic main spur gear ,slipper clutch ,plastic front and rear differentials.All of which will strip .The upgrades will cost another 200$+In my experience this is one of the best and worst Rc cars you can get ,best because it goes fast and the battery last about 20 minutes ,worst because out the box it breaks almost every time you take it out.All in all this Arrma truck was not great I have purchased others and they have been 10 times better .

The ARRMA 3S Big Rock Rocks!

Hello this is Hugh (Carols Hubbly Bubbly) This is my first "better" RC Truck, and wow what a difference! I think the best part is the Spektrum smart battery and Spektrum Smart Charger. (purchased seperately) A battery that will automatically discharge to a safe storage level (when no in use) is amazing. And when I hook up the smart battery to the smart charger it does everything else. No more need to research the proper charge rate, amps etc...This truck really goes! The only improvement I will make will be the shocks. At this price point I am totally satisfied with all the great features it has. (like the dual fans) So if your ready to make the jump to the next level of rc trucks I think the 3S Big Rock is an excellent choice. I already had a smart charger for my "no prep" drag car. I think the total investment for the 3S Big RockTruck (RTR) and Smart charger and 3S Smart pattery will be around $500.00 US . I could have started out with my 2S smart battery from my drag car if I had chose to go that route. Just something to think about. Now if only the weather would warm up a bit! Cheers
