Steve, I bought an all foam Jap Zero many years ago for a .15 RC combat. It's blocks of pink foam that you hog out just enough space to cram in the radio gear. The instructions encourage the use of miles of duct tape wrapped all over it. I never built it, thinking that it would end up being a brick.......but the instructions for this plane raved about how much abuse it could take. Depending on how extravagant you want to go with finishing touches, a basic down and dirty foamy build could go pretty quickly. Your spar notching tool would make quick work of that job.
A 32 incher would end up pretty small for anything but .049 to .074 power and would need to be less than 18 ozs to be a good all around flyer. 14 ozs is actually pretty doable for this size plane.
