Congrats on winning the new UCD 46 ... some guys have all the luck,
As for the damged wing you got from Great Planes...
By all means, send it back. If it were me (I tend to be the loudest gear) I would DEMAND a whole new plane. Even though your fuse and tail are not damaged as far as you know, the UCD is very lightweight and fragile. There could be damage there you are not aware of. What ever you do, don't tell the GP support rep you won another one for $5.
