if that is an ARF or an RTF airplane, then you will probably want to get a roll of monokote or ultracote and patch it back up so it looks better. just put the time and effort into it and you will have a perfectly good airplane.
ps- what kind of plane is that?
edit-
one of my planes does actually have a strip of duct tape on it, but that was a very minor repair.You underestimate the power of the Duct Tape.
edit edit- all of you guy that say it cant be fixed are totally wrong, like i said, i could have that plane in the air in less that a day. just get some balsa and some CA glue and it really will be good as new. if you go to any RC flying club, none of the planes are perfect, all of them have patches and countless areas where they have been repaired with balsa wood.
