Hi Keith,
I can't really tell how much damage there is from the photos, especially internally. Still, the wing is essentially intact. If there is a professional builder to be found locally, they could make a better assessment. I think papaone (his RCU handle) over in France could help, too ( he just built a very similar wing from scratch - it is in another thread here in the pattern forum). The existing wing could be reverse engineered to produce a replacement, too.
Good Luck!
