Great job all around here!!!
As for the issue about simply plugging the pylons into the secondary hull.....
I have no problem with that. That's how you attach the nacelles on the kit models. Prototype imitating art imitating prototype, you might say. It's been a while since I had one of those, but I remember that one nacelle on my model would sag a bit. Couldn't fix it then, but it'd be a snap now.
I'm looking forward to seeing more from you folks.
