just paint it. you are just learning from reading your post, and i'm sure you may have a few more, i did. my first skyray also met the same demise but i fortunately traced the plans first. so when building the next i added a 1/8" spruce spar in the center of the wing as i built it in four pieces . Front left and right as well as rear left and right. scanner would only allow this method as the wing was too long. i found this to add a little strength, but is still not fool proof. hope this may help a little.
