:rotf: much as I would like to boost power, it's going to be a while 'til he can handle that sort of speed. It'll happen :yes: but not anytime soon.
I originally wanted a bit of lift, some rubber tires, and a 4wd conversion (they have one electric motor per rear tire), but after examining the underside, there's nothing easy about any of those things. :( not impossible mind you, just not easy. bummer.
