I had a modified (dihedral removed) wing for my Avistar that I was planning on transitioning into after a little more flight time. Someone had given it to me years ago. However, the covering was shot and upon removal, there was significant structural damage. So I scrapped it and am building a new symetrical wing based on the Tiger 2 rib. I will also convert the Avistar to a taildragger prior to the new wing.
