getting into onroad racing...new motor?
well, I have been racing monstertrucks for a while now and I am getting into onroad a little.
My dad has an rs4 3 rtr that he has had sitting in the box for like two years now so I think I'm gonna start with it and then once I see if I really like/have time for it, I'll upgrade. Right now I'm looking for upgrades that will easily carry over to another kit later on so I was thinking of upgrading the motor. I know nothing about onroad racing, but I'm pretty sure I need a .12 instead of the rtr .15 correct?
what options can you give me seeing as I am completely clueless about onroad racing and its rules.
