I ran twin Monster Maxx motors in that thing until they burned up after 2 and a half runs, stupid pieces of junk. I tried using the HTI 700 or 750 or whatever the heck size it is, but it flat out stinks. No real torque, even less rpm. Granted it'd wake up with more cells, but screw it. I'm also too poor to do another BL plunge right now, I think I'd have to wait at least until Christmas for enough cash to do it, but I know it'd be cool. Sadly, that truck is constantly on the "possible selling list" due to bills, and because of the cruddy current running state......oh well.
