I was just going to say that schumacher belt drive systems are amazing. I remember whn I converted my MI2EC toruing car into a 4wd buggy and it worked so well offroad. I had it for over 6 months and I ran in dirt constantly. Never broke a belt and the belts when I sold it still looked to be in great condition. They had some wear but it wasnt anything bad.
Here are a few pics of it before I replaced the wing.
