A good place to start is with reading the beginners forums on this site. It looks like a project that was begun and never completed. The first step would be to stabilize what you have. The hinges for the control surfaces (flaps) are probably glue in hinges. They are just little plastic tabs that have fuzzy sides that Cyano glue will adhere to. If you can find a local R/C flyer who can actually look directly at the model he can give you more advice.
