You can glass the wing/fuse fairing all you want, but the problem really lies in the wing spar, which is part of the fwd and aft former.

This is what I would do and take it for what its worth. Cut the wings clean at the wing/fuse joint. Buy a set of wing mounting kits from Yellow (as used on the Epoxy version) and mount them to the bulkheads, then use the carbon rods to atach the wing to the fuse.

You will need to cut through the wing to add hardwood blocks where the carbon rods are glued in.

This is not really difficult and any damage done to the wing during the removal process can be fixed by adding balsa blocks and reshaping to match the airfoil.

There's many advatages to doing this such as:

-removable wings
-your current model has a rigid wing spar, you won't notice how bad or weak it is until it breaks.
-the carbon rods are actually flexible, so they help alleviate stress during not so great landings

You could also cut the rework time by 1/2 if you just buy a new set of wings from Yellow.

Best luck,
