My VsTank's run in the grass when it's mowed, but they tend to get grass wrapped in the wheels. The Leo really runs until it tears the plastic sprockets apart and the Tiger runs great (no grass, no breakage), but is too slow to enjoy. I love my 6 VsTank's for neighborhood battles in the culdesac and their amazing detail & quality. Since I only run in the suburbs, I do not have any dirt or patchy grass to really play tank. Think lush green suburban lawns for miles around, even at the parks and you will see why I need a larger beast to go offroading. I know the Pershing & Bulldogs were the best grass tanks back in March and the Bulldog chews less grass, but I wanted to see if that was still the case. My ultimate goal is to either put tracks and R/C gear on my lawnmower or have a tank/rover big enough to push it like a mine clearer.
