Assemble the wings, but, before attaching them to the fuselage, heat them with some moderately hot water for a few seconds, pull them out of the water, and immediately bend them to the warpage that you want, and run them under cool water. Repeat until you get the warpage that you want. Works in reverse for warped parts, too!!
