Granite Grom RC Car Review
I picked up the Granite Grom on a whim after a rough week, thinking it would just sit in a closet like half my other impulse buys. That was three months ago, and the thing still lives in my trunk. If youโre on the fence about grabbing one, Iโve got some thoughts.
First Impressions Straight Out Of The Box
The box itself doesnโt scream โmonster truck,โ but once you pull the Granite Grom out, the proportions make sense immediately. Itโs short, wide, and sits taller than youโd expect for something this small. I also think that stance is the whole point here. Itโs not trying to be a scale replica of anything. Itโs built to look chunky and act chunky.
Setup took me about ten minutes, most of which was charging the included battery. The 1400mAh 2S pack plugs in through an IC2 connector, and honestly, not having to mess with bullet connectors or worry about polarity was a nice change from some of my other trucks. Once itโs topped off, youโre driving. No soldering, no extra purchases, no waiting around for parts to arrive.
Whatโs Actually In The Box
Along with the truck itself, you get the transmitter, the battery, and a charger, so thereโs nothing hiding behind an asterisk that forces you to spend more before you can drive. Iโve bought RTR trucks before that technically needed one more accessory to actually function, so this felt refreshingly complete.

How It Actually Drives
This is where the Grom either wins you over or doesnโt. The 380-size brushed motor isnโt going to win any drag races, and Iโll admit I was a little underwhelmed the first five minutes. But that changed fast once I started throwing it at curbs, gravel patches, and my neighborโs slightly-too-steep driveway.
The power delivery is smooth, which matters more than raw speed for something this size. In my opinion, thatโs exactly why it works so well for casual driving. Youโre not fighting the throttle or getting snapped sideways every time you tap it. The shaft-driven 4ร4 setup keeps things predictable even on loose dirt, and the oversized dBoots tires grip surprisingly well on grass and broken pavement.
Suspension And Durability
The oil-filled shocks do more work than I expected from a truck at this price point. Iโve sent it off a curb more times than I want to admit, and aside from a scuffed bumper, nothingโs cracked or popped loose. The composite chassis flexes a little on hard landings instead of snapping, which tells me Arrma didnโt just shrink down a bigger truck and call it a day.
That said, I wouldnโt call it indestructible. A few of my harder crashes into a brick wall loosened a suspension arm, and I had to tighten it back up myself. Nothing that required tools I didnโt already own, but worth knowing going in.
Handling On Different Surfaces
Grass is where this thing feels most at home, honestly. The ground clearance lets it plow through overgrown patches without stalling, and the tires claw through dirt without much drama. On pavement itโs a little more twitchy since thereโs less give in the surface, but it never felt out of control, even for someone who isnโt glued to a controller every weekend.
Who This Truck Is Actually For
If youโre picturing yourself racing this thing competitively, look elsewhere. This isnโt that kind of truck. But if you want something you can toss in a bag, drive for twenty minutes at the park, and not stress about babying, this fits that role better than almost anything else Iโve tried. I also feel the same way plenty of other owners seem to online. Itโs less about performance numbers and more about how often you actually pick it up and drive it.
If youโre still deciding between something like this and a slightly bigger buggy setup, Iโd recommend checking out this breakdown of what actually matters when picking a beginner-friendly RC buggy before you commit. It covers a lot of the same tradeoffs I ran into.
Battery Life And Charging
One thing that surprised me was how much driving time I actually got out of a single charge. Itโs not going to run all afternoon, but for casual sessions it holds up fine. If battery runtime is a dealbreaker for you the way it was for me on a previous truck, Iโd also suggest reading through this guide on RC cars with longer battery life before you decide which model fits your routine.
A Few Small Complaints
Nothing is perfect, so Iโll be upfront about the parts that bugged me. The transmitter feels a little plasticky compared to some higher-end radios Iโve used, and thereโs no trim adjustment beyond the basics. Itโs also worth noting that replacement parts, while available, arenโt sitting on every hobby shop shelf, so you may end up ordering online if something breaks.
None of that changes my overall opinion, but Iโd rather mention it than pretend this thing is flawless.
Three months in, and this is still the truck I reach for most, which honestly surprised me. I didnโt expect a budget-friendly, small-scale monster truck to become my go-to over trucks that cost three times as much. I also think that says something about how Arrma approached this one. Itโs not trying to be everything. Itโs trying to be fun, durable, and easy to grab on your way out the door, and it nails all three.
If you want a truck that doesnโt ask much of you but still delivers real bashing fun, Iโd put the Granite Grom near the top of the list. Just donโt expect it to replace a full-size basher, because thatโs not the job it signed up for.
