Hatchet Lives!, well sort of. I've gone to great trouble and expense (around 15 quid ) to make a simple servo switch controller so it at least drives now although i've only tested it on an 8.4v Nimh pack thus far. Once i get paid i'll get a 5s lipo and charger, retread the wheels and i'll get a video of it driving and using the axe, should be pretty nasty on the new voltage.
