Obviously it will spoil lift, it was the idea of " excessive lift "loss that I was concerned about. I tried to put a basic photo attachment of the wing in question for everyopne to see but this forum is so limited in what it will receive. It's very frustrating as the photo was a simple scanned 3 X 5 snap shot in my Epson scanner. Maybe I'm doing somthing wrong. Actually photo of the wing appears in high lift section of Rc universe...wish I could send it here..Oh Mr. moderator can you help me?
