We can tackle that next, Bart! Making a Trooper would be cake!! The Rodeo that guy made is almost there! Haha really tho, it would be easy. I'd say choose the axles & wheels you want & scale the body off of the width they give you. There are 1.55, 1.7, 1.9, 2.2 size wheels & the tire sizes range from 2.6 to 6 - inches. You could probably even make the body from lexan because of how the Trooper is shaped.

You ever seen this one before? Tamiya
It's so expensive because it's so rare - I think it's the rarest of the CC-01 chassis kit varieties. Next time you go to Japan, look for it!
