Gonna experiment a little and try masking the windows before attaching and see how difficult it is to remove. If it works, will save time, if not, no big deal.
Little more work done tonight. Got the weights added so this should not be a tail sitter. I'll probably add a little more behind the engines as that should help keep the CG forward of the mains.
Now onto an issue. Dry fitting the fuselage to the wing revealed a major fit issue between the two. This is as far as I got for tonight, will try sanding some more tomorrow. Also the attempt at liquid masking the windows before attaching didn't pan out as the tolerances between the windows and the fuselage are really tight. So good idea but not gonna be practical.
