bigmig, im well aware of the limits vehicles have. i am simply trying to make the bulldog grip a little better so that driving it is more enjoyable. for the 100,000 time i am NOT CONCERNED WITH KEEPING TRUE TO SCALE. i cant seem to get that point across to any of you. if i was trying to stick to scale there are a **** load of things i would have done differently. as far as the snow goes i just want to be able to take it out and drive it without it getting stuck. if achiving this means the tank isnt performing to exacting cale standards then i sure as heck dont care. i just want to have fun driving it. im not sure what you and some of the other guys definition of fun is but it would seem to be making it run exactly like the real thing. if thats the case then your all screwed because the real tanks arent electric, and made of plastic. hope this helps clarify things for you, if not ill repeat that i dont give a crap about true scale in yet another message <br type="_moz"/>
