yeah, i knew that was a possibility, got the largest they sold, but it was only 2". I needed something else from the store, the sleeve was just something i added to see what it was like. I will probably either cut some long strips of fiberglass and wrap them starting at one end up to the other or i will cut 4 long pieces, maybe an inch wide and super77 them to all 4 "corners" and than trace out 4 pieces for the top, bottom, and 2 sides. Still thinking about it. Im not going for a perfect looking fuselage with this build or pretty shinny fiberglass. More going for a complete "working" v1 of the glassrat and than make another one better after.
