Looks very nice!
I am not a fan of how the fuselage is engineered to be constructed. A simple mod makes it very easy to build a perfectly straight box fuse everytime. I lay the top sheeting of the fuse flat on the board, and draw a ceterline down the length. Then mark the former locations on the fuse top using a square. Then mark a centerline on all of the formers. Glue all of the formers in place, at their proper locations with the centerlines lined up, and keeping them all all vertically square. Next add the fuselage sides, gluing them in place in the forward end of the fuse first. Then pull the tail together and glue the aft portion of fuse, keeping the centerline intersecting where the fuse comes together. Add tri stock and bottom sheeting. After trimming the top flush to the sides, you will have a perfectly straight fuse.
