    As good as this thing looks and as fun as it is to drive, l’m really disappointed with the fragility of this truck. Only driven at three times and it’s already broken one outdrive and now a rear suspension arm from just doing small jumps. Same thing with the 6S version. I feel like every time I take one of my Arrma vehicles out, something new on it breaks and I’m a very gentle driver. I’m honestly at the point now where I’m somewhat reluctant to buy anotherArrma vehicle.
