If the plane is made of EPO foam (and only if) medium CA glue will bond it. You can also use epoxy or Gorilla Glue (polyurethane glue) if you want a little extra working time.

And I'll second the advice you've been given to not go out and try to fly this plane by yourself. Chances are better than average that there will be mechanical or building errors that will make it unflyable at all, or at least not by an inexperienced pilot. It needs to be checked over thoroughly by an experienced builder and pilot, then test flown and trimmed properly for flight. After all of that is done, you'll have a chance of keeping it in the air for maybe 8-10 seconds at your beginner skill level. Be patient and start with an appropriate trainer plane and you will find a very enjoyable and reward hobby. But if you try to take shortcuts, you'll find nothing but frustration.
