I duno if I'd pull a battman & up to a tc5.... if you ever want to run TC, yes. Stay'n in TA....I'd just buy another tc3/4 roller, save some $ and maybe spend it on good esc/batteries. Give the kid one...and you'll have a spare car for parts if needed...sorry kid! If you got a tc5, you'll need another slew of spares..not much carries over from 3/4s except the shocks. my 2¢
Hope to see you at thunder today.. I think I'm going to pick up 4-5 pizzas for everyone since battman's forking up a cash purse.
