Finally broke down and had to measure and make a plan
. I just couldn't do it in my head. But I have a good idea of how the build will work. Had a couple attempts at getting the right scale from the parts catalog drawlings. Not all to scale and from page to page the scale changes. It's more for reference as to where the parts go, not really made for copying to a build scale. I'll have to get in touch with cat engineers and tell them to make their parts catalog more scale rc build friendly
And haven't settled on choice of motors/ drivetrain but thank you all for the places to look, it really helps me a lot!!
