Scratch building foam trainer, need ideas

Hello, I am scratch building a styrofoam trainer. I had some electronics just lyin around so I thought I would make something of all of it. Anyway, I need some ideas on constructing the wing. I have 1/4" foam sheet (the blue stuff from lowes) and a 1" thick sheet, but I dont think I need to use any of that. I was going to cut ribs out of the 1/4" stuff and wrap it with the same 1/4" foam. My big question is what should I use as a spar(s)? Also, do I need a leading edge or will the foam wrapped around the ribs be enough?

The wingspan is 48 inches, chord is 8 1/2 inches, and power is a regular speed 400 and gearbox.
