I don't think you want to build one from scratch. Just my guess but I don't think you want to do that. That would end up being a $500+ car. Trust me, I've done that before. I've converted a nitro mini into a Racer2 and then into a Super Nitro. Converted a Electric Sport2 into a Pro2. Converted a Nitro MT into a Super Nitro Rally. Even if you think you've got almost all the parts, one way or another you'll end up spending way more than you thought. Well, that's been my experience anyway. Just build the kit and add what you want later.
