Got myself a MA chassis to use for a little R&D. This set up, I believe, has some potential. The mid and rear rollers are for the straights and have very little drag. The front and rear are for the turns, with the o-ring front, it really seems to plant the nose. My testing consists of starting slow and working my way up in speed. Currently running 3.7/1 gears and a Torqued Tuned motor. Have a Rev-Tuned motor and 3.5/1 gears coming. So far, it is very stable. I'll update as I progress.
