RE: walker or pershing
The super version has a 10 step speed control, but most of the others (older models) have only two. If the item description does not state that the tank has 10 speeds, don't take for granted that it does, assume it does not.
Unless you just have to have a WWII era tank, I would say Get the super version Walker Bulldog. It is a newer, less common tank and has better ground clearance than the "Snow Leopard". [sm=thumbup.gif]
Good Luck!
