I'm back for a short time(work). I have a plan for the aft end of the fuselage to save time, I think. Build it as per the plans and "window" between the longerons and the up rites too lighten the
back end on the plane. All 4 sides. What do you fellas think? I have Bamboo skews that I can use for bracing,..done this on another airplane, (windows) and it helped out a lot..
