Fun inside and out
I have a few RC trucks, but they're all too large and fast to use inside. This truck fills that gap. This thing is SUPER fun inside, but is fast and tough enough to use outdoors. The unit feels very well built, and looks great, and being ARRMA you know youll have the aftermarket support for hop ups and replacement parts if needed. Battery life is great, easily getting 30 minutes of inside play before I slap the charger into it, and i don't think I've run the battery dry yet. Ill likely get at least one more of these because they're so fun. I really like the ability to limit steering at throttle, definitely well thought out features for a starter truck, that can grow in abilities with the user.

Fun RC Car!
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!

A+ Basher
Awesome basher, the only thing I would recommend right out of the gate is upgrading the wheels, but if you're careful on throttle you won't tear these ones up. Super fun very quick truck.

Just as fun as the big boys
*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.

Very Powerful and Fun to Drive
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.

This thing sucks
I have ordered 2 batteries and two new chargers. This thing is horrible. Got it for Christmas for my son and it wouldnt charge. Amazon sent another battery. That would not charge. I then ordered two more chargers and finally got 1 of the 2 batteries to hold charge , Which doesnt last long at all. This was my sons big Christmas gift , that he doesnt even want to play with. I need my money back. Come grab this piece of junk plastic.

It's good in stock form
It's fun in stock form, perfect for beginners. But if you go brushless, there's a ton of torque-steer. A gyro is a must. Unless you like to do heavy modifications, leave it in stock form or spend the outrageous price for the spektrum blx esc that comes in the Typhon or Mojave blx versions. I actually regret this buying one. But again, it's perfect for a beginner, just not so much if you buy it planning on going brushless without buying the crazily priced blx system.

Good for the price
Needed better differentials, but after that it's been great!

Kleiner Supertruck für Papa und Sohn!
Sehr gutes RC Fahrzeug für ab 6 Jahren! Der Truck macht den Kindern aber auch den Erwachsenen spaß. Man kann an der Fernbedinung die Gesvhwindigkeit 50/75/100% Leistung einstellen. So ist es ideal zum üben. Der Akku lädt schnell. Hier muss man wissen, das das Ladegerät nur mit der richtigen Voltzahl betrieben werden kann. An einem 65watt Netzteil hat es zB nicht geladen und ich war kurz davor es zurückzuschicken. Der Truck geht bei 3,1 Volt Spannung nicht aus, sondern fährt nicht mehr aber lenkt noch. Dies ist zum Akkuschutz von Spektrum so vorgesehen. Auf 50% Leistung hat man 20 Minuten reinen Fahrspaß und Sprünge mit Chrashs selbst auf Asphalt wurde bisher alle unbeschadet überstanden. Nichts für Eltern die sich mit dem Fahrzeug nicht befassen. Ein 6 Jähriger kann die Anleitung noch nicht verstehen. Ich baue jetzt eine RC Rennstrecke im Garten und wir fahren um die Wette. Entspannendes Hobby für Groß und Klein.

Indestructible
Perfecto para iniciar en el rc de saltos , por mucho que le des no se rompe , calidad arrma , si se rompe es por mucha mala suerte , potencia limitada pero se mueve muy bien , amortiguadores espectaculares de gran recorrido , conclusion … calidad precio de lo mejor que se pueda pagar con dinero .

Fun little grom
I love Arrma R.C gotta say one of the best makers in a long time, strong and easy to work on and this little grom granite is a blast, its a little slow with the brushed motor but rc 4 wheel drive makes a crazy brushless conversion that makes this granite almost to fast, big fan of these groms
