I would cut it the middle then prop up one side 2 inches and the other flat on the table that will give you your 1 inch at each tip .Once all the balsa main spars to touch right cut a place for a double made out of thin ply on the correct angles and use a little epoxy to glue them to the back of your main spars . A double about 12 inches or so long 6 inches on each side of the center joint should be enough so it won;t snap off later. As far a airfoils and other teck stuff iam not that smart but i have been building for 30 years now with not one plane that did not fly or fell apart .lol This one flys with a 3/32 main spar with 1/8 x1/8 spruse strips on top and bottom of it on the sides and i stagered the joints . I haved looped this 100 inch plane and nothing has snapped yet. I learned alot from the airfield site about building http://airfieldmodels.com/informatio..._panels/03.htm
