Ah, Gerwen, truer words have never been spoken. As of now, I've completely torn down my HPI MT2 RTR and Traxxas Electric Rustler and observed everything. Trust me, a year ago, I could have been scared to move the body posts up. Most of the knowledge I have received came from this forum, and I thank all of the members here for that. It's great to know what's going on, and the best way to learn is to just give it a shot and see what you find. Remember, if you mess up, it isn't the complete end of the world. The only thing I have left is to rebuild an engine... And I have an old one laying around right now...
