So far I built a 1/6 camaro, 2.2 are same size an factory ones and had to make my own axles.
And the one I made this thread about is the 90 percent 4 foot long dually I made for hauling this car around and what I based it off of is 1/5.5 scale it's only that scale because when I finished doing some modifications that it was 3 inches to long(1/6) and 4 inches to short(1/5)
