Hi Paul, I have been silently looking at your thread for some time, very nicely done, great piece of engineering!
Looking at your last fuselage design just a small note. The main former where gear and main wing spar meets has a hole not connected on the lower side. I had something similar on a model long time ago and it's prone to structural failure on a hard landing which could be unnoticed until next flight. Not sure if I can see it right but if you look on my addition below you see what I mean. The red line would be the tensile area prone to failure, I would connect it simply as drawn in purple. Maybe I did not see it correctly, anyway better safe than sorry!
Again, great work done here!
Cheers,
Gerald
