Thanks for the info. I mainly want to build a motor and some of the drive train but I only have a semester of metal shop and its high school, although its metal 3 (3rd year) I want to build what I can and buy what I cant build. But I'm looking to go gas for sure but I'll figure something out. Maybe I'll just buy a kit and replace/build, I'm not too sure yet. I dont have a large budget, maybe $400 or so but my main thing is finding a rolling chassis to put a motor in. I'm also looking to go pretty big too (damn go big or go home mentality), so far I found diagrams for a 28cc motor which I'm thinking about doing, not too sure about anyting yet.
