SigMan, if you have any doubts, send it back. Although it is a hassle, I would continue to do so untill you have gotten what you have paid for, a good wing. If you are up to it, pull the covering on affected areas and do a repair, although I do not feel that is your responsability. All in all, the replacement or repair will be well worth the effort. The plane is sweet. This model should be illegal as it lands so effortlessly and responds to commands so well. Beautiful craft and well built, very durable. On training night I get to fly three of them, two with Saito .72 4s and one with an OS .46 2s. Good luck on your venture and I know you will enjoy this one. Joe
