Review: Best Bang for your $$$ - For the price, it doesn't get any better. For the size it has just enough power to be a perfect driveway/backyard basher. If you want more power, you can convert it to brushless for around $30-$50 and better shocks for around $40. The part support is going to be great because its name brand. Its perfect for kids and plenty of room to grow for more skilled drivers. I love it. The only thing that I would change right away is the shock oil, it is a little too soft. I would put about 40wt or 45wt shock oil in it.
Review: Amazing Truck - It's built really tough, my son has crashed it into rocks and sidewalks and nothing has broke. The steering did become unaligned but it was an easy repair with no parts needed. Plenty fast for a brushed motor. Excellent value for the price. The only upgrade I recommend is the 100w charger with the screen to show you all the battery info. Update: The diffs finally broke like others had said. My son was beating the hell out of it, but it should have lasted longer. The internals are mostly metal, with a small plastic gear- that's the weak point. I bought knock-offs here on desertcart for half the price of the upgraded ones sold by Arrma. The fix is easy, just wish they included the upgraded diffs with the car.

### ⭐⭐⭐⭐⭐ Great car.
*by R***H on September 4, 2024*

Worth every penny, however the charger broke, as many others have complained, almost instantly. Since I was doing a brushless upgrade it wasn't a big deal for me. Way faster and better built then my Latrax and that's without ever being able to actually charge the factory battery. If you plan on keeping the car brushed, nothing wrong with it plenty fast from the factory, buy a decent charger or change the factory leads and enjoy. DO NOT expect the factory charger will work. It's crap and they'd be better off not including it. It was only a capacitor that went bad, a simple fix. However there are approximately 0 schematics that tell the specification of that capacitor and I tried 4 different ones none of which worked. I ended up deciding since it charges lipos it wasn't worth the risk to fix. Put too large of a capacitor in next thing you know it's charging to 4.8 volts. Just expect you need a charger from the beginning and problem solved. Update: I just bought a Typhon and the exact same thing happened. So it's definitely the charger. Skip this unless you want it as a chassis. In other words you plan to go brushless from the start or buy a new charger.
