Dave's wings are the same airfoil as the Temptation and they have a different sweep on them. The sweep is the same as a Phenom which brings the wing tips forward about an inch. The foam is expertly cut by Mickey Losardo and Jim Hubbard and they are balsa sheeted. I have the exact wing on my Shmorphidite (modified Smaragd) which I'm flying this year. The wing gives the plane amazing stability in the air. It's as steady as a rock. We will more than likely be using this same wing on a different plane next year. It's gotten to the point with all the modifications that the fuse is just a device that holds the wings in place.
Here's a pic of the wing. You can get a better idea of the difference in the sweep from it.
