OK, you can not stack prior to the start. If for some reason you did want to stack, what would you do about that little thingy called a FLAG HOLDER that must be at 51" in the Playing Configuration?

This thread does make me thing of something else though, how fast and stable would say a three robot train be (think nascar), front to rear or side to side? It would be interesting to see if nothing else.
