Quality truck
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.

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!

Coolest little Arrma Granite 1/18 scale truck
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.

Great truck
Fun for teaching my son how to handle an RC. Can take a beating! He is 4 and fell in love with my larger Arrma. This thing zips, jump, and has taken every crash thrown at it. I suggest purchasing a larger battery and charger. The ones it comes with aren't the best but will work fine to start.

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.

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.

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 .
