oh, I thought that you're the lucky guy
Regarding the wing tube, mine is a really tight fit and when I mounted the wings to the fuselage the first time it seemed like the wings didn't want to squeeze in tight to the fuselage. I just checked and the wing tube is 1/16" too long. When the wings are on the tube (but not on the fuselage) there is a 1 1/4" gap at the root but the fuselage is 1 3/16" thick. I'm going to cut 1/8" off one end so the wings will be able to pull in nice and tight to the fuselage sides when the bolts are snugged up.
You guys might want to check yours to see if you have the same problem. Also, I had to sand my wing tube lightly to make it go in and out of the wings more easily. The way it was was way too tight!
fwiw, Carbon Fiber is really bad stuff! If you decide to cut your wing tube make sure you don't breathe in the dust and also don't let any micro fibers dig into your skin. Your body won't build up a bruise around a carbon fiber splinter the way it will with any other type of splinter so it could end up staying there forever (!!) if you can't get it out!
Just finishing up today and it'll be ready to fly. It isn't a long build, it just took me longer than normal because I'm trying to document the build with videos here and there.
