Thank you.!
No indeed Terri, no wing sag. This variant called for the slots on the fuselage to be cut out in a higher position, and the originals filled, which is potentially why there was such a tight fit. Never mind having no paint on the wing tabs, I had to sand them a bit to get them into the slots I cut. Better that than making those slots too big I guess.!
I need to make the swirls better next time, they are barely visible on the photos.
