Thanks for the input guys. What I ended up doing was putting a piece of tape down the middle of the wings (on both sides) and then drilling about 5 holes with a 1/8 bit (did it on the bottom of course). I then took some 45 min epoxy and soaked it in the holes and left it to dry over night and removed the tape. Everything seems to be good and tight.

Thanks once again for the input and happy flying
