Yes, useful exercise for students.
The numbers above can't be used, of course, to answer the original engineering question, to wit: all other things being equal, how much acceleration advantage does a 4" wheel vehicle have over a 6" wheel vehicle (where both the 4" and 6" wheels have been reasonably individually optimized for the vehicle).
Does anybody have CAD models (from this or past years) of 4" vs 6" drive train options which included enough detail to calc the mass and moment of the wheels?
