Mr. Kevin,
Are they warped near the glued seams? Did you use a wood glue, CA, or cellulose like Sig-ment/Ambroid? I can't tell from the photo.
Thinking out loud here:
Did you block the wing flat on the surface with weights encapsulating the entire wing after assembly with wax paper on both sides? I can only think humidity from the glue drying caused un-even humid spots and then warps. This would have been exacerbated by the wax paper holding humidity in during the cure/dry time.
Are the warps bad? Maybe misting the wing with ammonia/water or steaming to relax the wood, and then blocking with small weights will get it flat again. Include an air gap between the wing and flat surface.
I like a hand full of Legoes in strategic locations, like short piers, under the wing, and weight from above over each pier to ensure flatness. Let dry 36-48 hours. Try to do the work in an air conditioned space to minimize ambient humidity.
