it would be similar to running it on 2s, would be alot slower. however you see some horror stories about lipos but they are few and far between, ive been using lipos for over 8 years and been using them for racing so high amp charge and discharge and never had an issue. Don't get me wrong if they can be dangerous, but i wouldn't let that put you off, just do plenty of research on how to charge and store them.
