Mike,

What is the main difference between the stock Smaragd wing and the one that you are currently using, is the stability due to bigger wing area? If you don't mind sharing.

Up to now, I consider my Smaragd Z one of the best airplane I have ever flown. It rolls nice, and the up and down line snaps are the cleanest, it really stops on a dime. I think it has a lot to do with the double tappered small wing.
