RE: .21 vspec or .28 LRP?
There was a pretty informative article in one of teh rc mags debating 21s vs 28s.
In a nutchell they said that most race level 28s are just overkill on power, and ran faster lap times consistantly with a 21.
They said if you were gonna run a 28, that a racing one was unnecessary, which I tend to agree with as my 427 in my Jammin CRT makes more power than I can use or even put down effectively/
