I think 2 changes are needed. I offer up:
allow them to grip and turn better than wheels…at least if it out weighs the wheel build. Small dogs shouldnt be able to pin and prevent rotation.
allow the acceleration to correspond with the build PS. They are playable with only 2 grinders but are quickly outclassed when going to 3 or more
Because cabin power doesnt change with PS, it leads to sluggish movement at high PS when not on hovers.
