    • Great rc truck, does great in grass
Color: Green
Absolutely love this truck, got for my 6 or old B-day, he loves it, but it is advanced for him. Be ready to learn to replace A arms, but this thing is so fun, so fast, and very durable relatively speaking. Doesn't come with battery or charger, but at $320, it is shockingly fast

    • Awesome truck!!
Color: Black
Amazing car,very sturdy and super rigid,my only complaint is I cant seem to get any battery pack to last over 10 minutes,just heard i need to cycle through a few charges for them to last longer so we will see. I do wish I would have got the quake or notorious because I really like popping wheelies and the big rock will do them but not as easy as my mini xrt (on 2s) or my deerc 8618 but still a great RC truck ... show more

    • This is the RC Truck you've been looking for
Color: Black
My 5 year old son and I absolutely love this truck . We've tried many other brands on Amazon and none of them seem to stand the test of time. they always died fairly quickly. But this one takes a beating and keeps on going. No cheap parts on this beast and it's super fast. If my son didn't have so much experience with all the other previous RC trucks...there's no way he would have been able to handle this one. If you're looking for an awesomely fun RC Truck? Look no further because you just found it. ... show more

    • Very Disappointing. Beware common issue.
Color: Blue
We ordered the Arrma Big Rock with high hopes reading many reviews of people that loved their truck. My son also has the Senton, which he loves but we can't keep tires on it.....pretty fast 3S set up. But the Big Rock, is absolutely the biggest pile of junk I have ever purchased since I started buying RTR/Kit RC cars 40 years ago. Brushless Spektrum motor straight locked up before the 2nd battery was run all the way through. In fact, maybe 5 minutes after the battery swap. I thought it was the rear diff or the center diff/trans but once I disassembled it, the motor was locked up completely. I had to use some fairly large pliers to get the motor broke free and then it just sounds like either the entire inside exploded or a bearing completely failed. After some research, this seems to be a fairly common issue with the new Spektrum brushless V3. I can not testify to the toughness of the rest of the truck since all the time playing was on flat grass and pavement and we haven't made it through even 2 batteries yet. Maybe the older ones are better and more durable, but beware of the newest ones with the Spektrum. Not sure if there is warranty or anything to cover the new motor, or if Arrma is aware this is an issue. I did see a video where Horizon hobby sent a guy a new motor (NOT Spektrum) under warranty and he did not have any issues after that. ... show more

    • Crazy fast and super fun
Color: Black
Review Image by Tyler C.
Insanely fun and versatile truck for tracks, offroad, and jumps. It is extremely fast and built very well. However, I noticed that when jumping of ramps the body tends to come dislodged and loose. And not even that crazy of a jump. So that was disconcerting but definitely doesn’t ruin the fun of the truck. For that, it’s minus a star. Highly recommend. ... show more
