My Bulldog with metal tracks, steel gearboxes, Graupner speed 400's and 1500 BB's in the front for weight absolutely owns the grass. My Panzer 3 with the Asiatam hull sits low enough to run in grass, but those skinny little treads tend to lose traction. Maybe I'll get some of those winter tracks, sharpen the blades and use the Panzer 3 to mow the lawn. Suburbia sucks for tanks.
