HELP.....I am building a SIG Ninja slope plane. It has sheeted foam wings. I just pulled the wings out of the shucks and one of them is warped. I cant figure out where I screwed up, I glue and pressed them on a very flat surface (Delta table saw) but one still came out warped. Is there anyway to unwarp it now? Or do I just start over with a new core? If it was all balsa I would steam it and bend it back but I dont think this will work with the foam in them. Any ideas?
Thanks
