Does anybody have any idea how I might be able to repair a styrofoam wing? I bought a trainer that had a styrofoam wing and I kinda crashed. I didn't do alot of damage just a little, but I tried to fly it after I crashed and well when I got my plane in the air it started to go in the direction of the gash that is out of the wing. I was thinking about some triple expanding form. But does anybody have any other ideas?
