🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.

The Arrma Big Rock RC truck is generally received with high praise. Many of the reviewers have talked about the excellent speed, durability and value for money. The truck has also been described as tough and well-built. However, there are some concerns about the parts needing replacements after intense usage.

Pros

  • 🚀 Incredible speed even on 2S batteries.
  • 💪 It's solid and tough, capable of enduring hard usage and crashes.
  • 👌 Offers value for money when compared to other more expensive models.
  • 😃 Great fun and can potentially attract attention from bystanders due to its performance.

Cons

  • 🔧 Some users have reported needing to replace parts after only a couple of weeks of intense usage, which could add to the overall cost.
  • 🎮 Might be too fast for beginners and require getting used to the controls.

Should I Buy It?

If high speed and durability are what you're seeking in an RC truck, then the Arrma Big Rock is certainly a strong choice. Owners have been thrilled with its performance and fun factor. While it might need some parts replacement after intense usage, many consider it a worthwhile trade-off given its other strengths. However, beginners might want to approach with caution due to its high speed.

    • 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 brushed 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! ... show more

    • WOW! Great truck
Review Image by Kynan Kynan
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. ... show more

    • Has to in the top 5 of All Time RC Trucks

Just like the title says. Has to be Top 5 at least. Defnitely in the conversation of all time 1st RC buys. Infinitely customizeable, tough, fast, you name it. At the end of the day, this truck will give you what you put it through. I drive my RC's pretty hard and have had my fair share of breaks and damage, but with the design of this truck, you can tear it down to parts and rebuild it with minimal knowledge. My 7-year-old has broken this thing more times than I can count and he's rebuilding it from ground up easily. Since we got this model, we've added bigger tires, chassis braces, various metal parts, and even went with a center differential to throw out the slipper clutch. The parts market is pretty big, and this model's parts are interchangeable with almost every Arrma 1/10-1/8 model they have out. Never once regretted this purchase. ... show more

    • Takes some tinkering, but a beast once dialed in

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. ... show more

    • Great 4x4, but plan to spend money on parts if you like to bash hard..

Great truck, lots of power, but, could have been designed a bit better IMHO. My first ten minute run, I hut a curb head on (wasn't paying attention). The force of the impact caused more than a couple issues. The motor mount chassis didn't hold up and had a huge crack, at the same time then entire motor shifted due the the motor mount plate bending. The spur gear took a good portion of the force as well, and actually cracked. Couple other small issues onto of this, but, ended up spending $120 after shipping costs just to get back to new. I'm planning to do a feew modifications before I bash again, starting with support for the motor (both underneath, and at the rear to protect the motor mount plate from doing this again. Sure, I wasn't paying attention when I hit the curb , but, I've seen guys launch this truck 30' in the air off skate park ramps, and land nose first, and keep on riding. Which, is why I bought it. I've ran my Arrma typhone through the ringer, and I mean hard, and have not yet had to replace anything. I'm going to get this Arrma Big Rock to the same standards with some upgrades.. ... show more
