I did that on my revo, but I didn't do it on the 3.3 jato pipe. It seemed bigger bored to me, but then again, with the 18TM, it's already too much power for what I do. More power will just make it harder to control.
I put the arms on yesterday.buy before I do anything else I tore the top chassis plate off and cleaned it till she looks new. I am puttin on my hump pack tomorrow and my failsafe and roll bar. And I will post pics soon.
