To answer question one, I always believed this rule was to prevent the beams being permanently glued to the hulls (Like most modern A Class) So therefore I can never imagine a F16 without beam bolts.
As for the other questions I would speak to one or all of the technical committee before parting with your hard earned cash, that's Peit Saarberg, John Pierce I think Phill Brander and perhaps Greg Goodall?
Maybe somebody from the Governing Council could confirm.
