This doesn't need much explanation; all-out hooning on some nicely-graded dirt pads with the Traxxas converted to off-road spec (long shocks, chunky tires) wearing the alpha version of the ARX offroad body.
End-over flips off a poorly-landed jump aren't very good for the longevity of prototype paper bodywork. It's done its job, though. Compared to how nasty the chassis usually gets when running the Rally body, this is relatively tidy.
