I'm only seven months into 8th scale, but I felt like the car became more consistent with lipos and a regulator. Or maybe I just finally started driving better. lol. Either way, I bought lipo after putting too much juice to one of my other Nimh packs an blew it up. Also I have a 2000mah lipo and there is barely a difference in weight compared to the other 1400nimh pack. I have no scale, so take that how you want.
