Totally the opposite process of what I normally do. Because I have 2 rolls of 1mm Depron foam and there it sits staring me in the face saying pick me I need to build something with a rolled fuse and nice smooth airfoil wing. Instead of the spars there will be wing ribs and a 5mm cf rod with maybe some balsa strips for the LE and TE, control surfaces will just be out of 6mm foam (I think) . Figured I would start small and easy (flat wing) and because it is a winner when it comes to flying lets use the FT Bloody Baron. So just the opposite I built a 3D version of the baron using 6mm foam (in a sense) from the plans. Now to start designing a fuse and main wing, not sure what I will do with the rear end.
