It is a Tamiya TB Evolution IV MS version. The rear diff incorporates ceramic balls which I think are going to prevent the diff rings from melting with the balls or atleast the balls wont deform, because of extreme heat. The car has a set of ceramic ball bearings and to tell you the truth the car does not go much faster than when it is with the regular ones, but the drive train is surely spinning freely and smoothness is at its peak. I still need to make some mods on the lower deck to make the three cells hold tight to the chassis.
