Still running a ft ntc3. Its a solid car, better for shorter tracks. Due to the gearing contraints this chassis is cursed with, the mugens, serpents, kyoshos, xrays, almost any newer gen chassis for that matter will pull on the straights. So if you are gonna be racing a large track,(150ft straight<) the ntc3's shorter 2nd gear will be a liability.
Good luck with your decision.
