    • Quality truck
Color: Blue
Review Image by Steve
I think for the price point, this is the best value for the money. This truck is well built and pretty fast. It doesn't do the best on crawler terrain or taller grass. This is ok though, it wasn't meant to be a crawler. I have had it for several months and am not nice to it, hasn't broke yet. I also like the clip less body mounts. Definitely don't regret this purchase. The picture I posted is with bigger tires than it came with. ... show more

    • Very Powerful and Fun to Drive
Color: Red
Very powerful and fun to drive. It feels like a real monster truck in a smaller scale. The performance is great and I’m very satisfied overall. The only downside is that it does not include a charger. Other than that, I’m happy with it.

    • Fun RC Car!
Color: Red
I got this on sale for $108. This has been one of my better buys. I like this rc car. I got the V2. Downside being the plastic on one of the front outside axels failed and the axel popped out and disappeared somwhere. Waiting on the replacement metal parts now from Arrma ARA-311198($40 bucks). Upgrades add up quick! ... show more

    • Just as fun as the big boys
Color: Blue
Review Image by Steve
*1st Thing, this must be a version 2, because there are tons of videos talking about it coming stock with plastic dogbones, differentials and all that. Not anymore, everything including the planetary gears in the diffs are metal (planetary gears look to be aluminum though). And also your Arrma logo on the front won't be white, I did that. Anyway, if you know about Arrma, it's Arrma tough, enough said. If you're new to the hobby, get it, you'll love it. It's tough as a tank, quick for it's size, runs smooth and quiet. If you charge the battery with the accompanied charger, get a higher wattage USB-C cord and use a high wattage charge block and you can charge the battery pretty quickly (less than an hour), otherwise plugging it in your laptop or something like that will take forever. ... show more

    • Great starter RC car. 5yr old loves it
Color: Red
It’s a good starter RC car. Purchased for my 5yr old daughter as she always watches me play with mine and showed interest. Started her on 50% power then moved her up gradually to 100%.

    • Fun car for my 13 y/o! Great Christmas gift.
Color: Red
The media could not be loaded. Got this for my 13 y/o son for Christmas and he loves it. It’s a great RC car for a kid who is transitioning from little kid toys to more adult stuff. At the price point this was the perfect transition car for him. Easy to drive, super fast, durable, decent battery life. The one thing I’ll say is it takes some practice and fiddling to get the body on and off. I don’t love the design. It’s supposed to be super easy and idiotic proof but both my son and I (and my husband) struggle with it. ... show more

    • Fun, for a while.
Color: Red
Great little truck, certainly takes a beating! But.. the batteries are junk. Less than a year old and it will not take a charge anymore.

    • Coolest little Arrma Granite 1/18 scale truck
Color: Green
Received in brand new perfect condition. Very well packaged. I own quite a few buggies now. This is the smallest one of them all. Just unbelievable how well it performs. 2s works really well in theses sawed off jobs. I really enjoy driving this little guy around the house. It’s so small compared to my others and I’m afraid to take is outside. It might get lost or a bird might take it away. Not to mention all the Coyotes running around. But seriously this is a cool little hobby grade truck. I like it! Runs perfect and very happy with my purchase. ... show more
