Wasnt thinking 4wd on this one, I've got my Gorillamaxx revo for that !!
I think it would be pretty hard to make it 4wd with the extreamly long wheelbase .
I made the wheelbase 22 inches . I think that was the same as the HPI baja. I have a 9XL and 2 2s trakpower batts at the moment I bought for my G-maxx , but have since picked up a quark Monster-pro . So now I will be able to run a 6s batt !!! I will set it up with what I've got but plan on bigger and better power soon !
