No, no, no, Wiley, you screwed up the top saucer shieldgrid on the Excel again. There isn't a line that goes on the longitudinal axis, it's offset by 9 degs (Since the Excel has 5 segments per 90degs, so 90/5=18, 18/2=9 if you want a segments middle on the longitudinal axis). The bottom saucer shieldgrid starts out on the longitudinal axis however. You nailed the aztec down this time, but you still made the base duck-egg again instead of satin white tho.
As for the Constealltion nacelles, they're the same as on the Connie only with a part of the aft cut off.
