I found that the biggest improvement was going to the lower holes for the upper arms. If you check back a few pages you will find a setup posted by Kevin K that works well as well as one by me that I like. You should have no problem running with the Losi's and TC3's with either setup. Of course tires and inserts make a big difference, I prefer Yok 139g or 139gs (for lowerbite tracks) with Echo red inserts.
