🚀 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.


  • 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! ... show more

  • Best rc car
I absolutely love this car. Love doing flips and jumps and everything in between. Super easy to use because you can adjust how much power the car gives off from 50%-75%-100%. It’s very good for the money you pay and is super fast going up to 50 mph. It’s so much fun ripping around grass fields or hitting big jumps. ... show more

  • WOW! Great truck
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

  • Excellent truck and definitely worth it
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... 😉😉 ... show more

  • Hot Garbage
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. ... show more
