i would use either white elemers all glue for the wing/fuse (asumbing they are foam) or expoy (walmart/homedepot/lows/towerhobbies/ect)
even though it may not look great it will fly again.
another tip is if you have some "chunks" taken out of the wing/fuse that are to small to glue take some foam from another source (insulation/packing/ect), then cut a square out of the airplane and replace it with a square from another source. then sand it to look smooth again. (your cutting the messed up portion out, replacing it with a peice that is to big and sanding it into place)
sorry if im not explaining this very well
