Why I am not trying to pull the wool over anyones eyes. You ask most scale racers (like Slim and Czech said) thats a tool you never get rid of. The Hudy is way more accurate and measures toe, camber and steering throw. The rpm gauge only measures camber. So they are different in many ways. people ask why I am getting rid of it, so I said why. just because something is easier for me doesn't make it difficult or easy for somebody else. If no one buys it I will keep it and use it
