M5: I am sure people here just want you to think twice before you get the 4-tec. Generally people think that its less competitive then other nitro cars they mentioned. Anyway, if you feel comfortable about getting the 4-tec, why not?
I want to point out 1 thing, don't trust everything on RCCA. I always feel that their views are quite biased, just my thought.
999: Masami do race nitro, and BK also have not bad results in TC
