A: There was a mis-understanding on our side on what the "orange circles" referred to. You have correctly pointed out that <R9a> prohibits modification of motors. Tapping the holes in the LEGO Motors would be a violation of this rule. The original answer was not intended to be an exception.
To any team that has tapped the holes in their LEGO motors: Do not use the tapped holes and your motors will be treated as "unmodified" for the purposes of inspection.
A1: We are not sure what you mean by the green plastic bands. If you are talking about rubber bands, those are legal (#32 size). If you are talking about the tank treads, gears, or something else, then they are not legal. As for the Intake Rollers (the vex rubber stars), those are not legal.
A2: For this year's game definitions, wheels are not structural parts. We consider the vex metal pieces (bars, channels, plates, angles, etc) to be the structural pieces.
