ARRMA 1/10 Big Rock 4X4 V3 3S BLX Brushless Monster RC Truck RTR (Transmitter and Receiver Included, Batteries and Charger Required), Black, ARA4312V3

Plenty of reviews everywhere on the Big Rock so this will be short. We have a couple of smaller ($100 ish) R/C's that I bought to race around with my 10 yr old. First R/C's I've used since I was a kid. They are fun, durable, pretty fast. Nothing like this. Big Rock is fast. Way fast. Very durable. Yeah, we've broken a couple of minor parts, but considering the crashes, that's nothing. Nice to have 50/75/100% speed modes so my son doesn't worry as much about crashing it. Nice to have steering travel limiter as well. All black body means that you can get creative if you want. Paint pen works great. Only thing - switch out the tires. Stock ones deform massively at speed making the truck less stable. Grab some tires off of a Granite or similar and the truck will be much more stable and fun.

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!

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!

I love just about everything about this truck although the rear wheel just fell off after going through about 6, maybe 7 battery packs but was an easy fix. Otherwise I absolutely love this product and it is super fast even with a 2s battery. If you're a beginner I suggest buying a 2s battery and a 3s battery so you'll have a chance to get the hang of the controls cuz its kinda hard to drive unless you got the hang of it. I got two of each batteries and I should have only gotten one 2s and two 3s cuz I'm not using the 2s batteries at all anymore now that I have a good feel for it. But this truck is in a totally different class than the cheaper ones out there, it can ride a wheelie all the way down the street and do donuts and backwards donuts and all sorts of other sweet tricks and it can really get some air on the smallest jumps and it's so fast that it almost looks like its hovering across the ground and it will zoom throughout any yard super fast!!!!! I almost think its too fast!!!! It says 50mph on the box but 50mph never seemed so fast before now, I swear!!! This thing is awesome and absolutely worth every penny and I would probably pay a lot more for it than I did, which is awesome too cuz you really feel like you got a good deal on it and It's built stronger looking than any other truck I've had!!! I've seen several $800 to $900 trucks that were not as nice as this one and that says alot to me!!! I recommend this truck to anyone who wants to have some serious fun and feel like they got a great deal!!! P.S.- Make sure that you check your battery connectors before buying batteries... I'm pretty sure it comes with EC5 connectors but double check before you quote me... 😉😉

Day 1 was great. On 3s lipo she moves. But I have become very wary of bashing it. First off, I went through all the nuts and bolts with blue locktite when I got it. On day 2 I was just spinning a few donuts and one of the wheels flew off. Put it back on and went for another run. Another wheel flew off. Put it back on. Re-locktited them both. Went back out and the first wheel flew off again. Locktite again. I think it's having problems with the wheels because the nuts are tiny(4mm) and barely any axel pokes through the rim. So all in all it's a great RC, as long as the wheels aren't flying off. Edit: disregard my first review. I've taken this out a total of 10 times. Just hitting homeade jumps. Something has broken every time I've taken it out. I haven't even bashed it! I've come to the conclusion that this rig is just a piece of junk. Save up another $100-$150 and buy something better. The Big Rock is crap.

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.

First off, loosen the slipper clutch. If you run a 3S battery without backing it off a bit you will rip the rear drive axles apart within 5 minutes. Also, buy more shocks and extra drive axles, both will break in time. I’ve had this truck about a year now and have broken it probably 15 times so it’s a part hog. HOWEVER, once you get everything dialed in this truck is an absolute monster. I bash through muddy wetlands, snow, sand, grass, pavement, and it’s handles all terrain the exact same. I love and hate this thing because it’s ridiculously fast and fun to drive, but so much power it shreds it’s plastic parts. It has its own toolbox full of replacement parts, but I am pretty hard in it.

**Sorry for the crummy pictures, I took screen shots of a video I made** I'll start off by saying that I have been in the RC hobby for 15 years or more. I used to race regularly, and I was the co-owner of a successful track here in the south. I've owned countless RC, ranging from tiny micro RC all the way up to 1/5 scale gas powered. This Arrma Big Rock is probably the most fun RC I've owned. If you want to take it up a notch, use a 3s battery. On a 3 cell (3s) lipo battery, it will have more power than you can even use. The other big plus is the fact that it's so durable. I've had this Big Rock for a year and the only thing I've broken so far is a steering servo. I definitely don't baby it, this truck has been put through the wringer. I've launched it at least 15-20 feet into the air at the local skate park, and even when it lands back on concrete, it just keeps going.

Die Randmutter vorne links hat sich gelöst und die Madenbschraube, beide sind verloren gegangen.

The quality of the arrma speaks for itself but I genuinely thought I was buying an rtr unfortunately my son opened it for Christmas with no battery or charger

When they say arrma tough, they mean it. I always roll my eyes at advertising lines. Seriously, tough. Awesome bashing platform, handles the track not too bad , does backflips on steep jumps with ease. I upgraded to big bore shocks, which I highly recommend. Slightly faster top end then the Typhon I own both same gearing, motors and 3 cell lipos. The big rock pulls away because if it’s bigger tires, get that little bit more speed out of it. I got my big rock on sale for $349.99 in my opinion that is a steal, I paid over 500 for my typhon after the tax man. If you’re looking for an all-around good buy I would highly recommend this one do to its versatility. If you want something to stay on the track with, I would get it a typhon. Only dislike I have about the truck is the wheel axles and the 14 mm Hex adapter? The ones on the typhon are way better. I’ve never bent or broke one due to them being thicker made for the 17 mm hub adaptor. Can easily put typhon wheel axles on the big rock to make it that much tougher and you have a much larger selection of tires this way. I have broke some parts like the steering carriers which is expected if you’re hard on it and I have bent wheel axles, stripped a couple output gears. Everything was very inexpensive to replace, and I highly recommend replacing everything with OEM parts. None of the aluminum stuff.. u could buy a dozen plastic ones for one of the aluminum anything, keeping the weight down with the plastic parts and letting the design of the model to brake on in expensive parts, rather than ripping, a whole control, arm off, etc.. one other thing do not get sucked into the aftermarket, heavy duty, steel, cvd aftermarket axles. Once again they’re heavy taking away your performance, I have been extremely hard on the OEM axles and have never broken. I have only wore them out and it takes a long time. And for the price of OEM to replace you could buy four sets for the price of one aluminum set there’s really no reason. Hopefully I covered most things you want to read before buying. Blah blah blah. When it comes to buying arrma OEM parts I find the descriptions on the parts are not very good, part numbers don’t really add up either and i find myself relying on customer reviews to make sure I have exact fit for my model. So thank you to those people who left a review and would appreciate if everybody left a review, saying if their parts fit or if they did not fit, and if they fit state which model it fit, blah blah blah. 👍

I own too many hobby grade RC, at least that's what they said at my intervention. My first arrma was a vendetta. After being so impressed with the quality of it I immediately bought a big rock when amazon had that awesome deal on arrma a while back. This is my daily basher now. It just rips on 3s, a blast to drive. My only advice is to research wheels coming off. It's a 15 min fix with some blue loctite on the 1 screw inside each of the outer driveshafts (4). Trust me. I had one come off on the second run. Did the loctite and haven't had an issue since. Also check the wheel nuts after each run in the beginning. I had one loosen a bit twice on the back right, changed the nut out for a new one and they have all stayed snug since. It's bone stock power and drivetrain wise, other than some 3d printed roof skids, fenders, dust cover and a motor end cap I printed out of TPU. None are necessary, but research the motor cap, apparenty ultra hard landings can bend the motor plate. The cap helps avoid this. I don't jump mine 30 feet in the air, but just because you see youtubers do it, doesn't mean yours is bulletproof and can do it too. It just takes one landing off a bit to break it good at those heights. Dont get me wrong, I drive mine hard regularly without issues, just not stupidly. Full runs on 3s and I can still touch motor and esc. I have traxxas that will burn you a nice blister after a hard run. All in all it's one of my favourite 4wd bashers these days as my ERevo now sits quietly on a shelf, hiding under some dust.

Bought this truck because it got good reviews the truck itself is great but have been having a problem with the ESC right out of the box contacted the manufacturer just to get the run around worst customer support I've ever had I will be returning asap very disappointed when you spend almost $500 and receive a defective item and the manufacturer doesn't seem to want to help waste of money
