All glass is a "good thing" for hlg wings. My Uplink uses a single layer of 1.4oz glass overall with a second layer extending out about 5 inches from center on the top and 4 inches on the bottom. I put a shear web in out to the poly break at about the high point in the wing and cap it with a 1 inch strip of 1.4 oz glass. I use 0.013 inch pre cured glass for the shear web but a strip of 1/64th inch birch ply will do as well. If you use any carbon in the wing, you need to put enough in to carry all of the load as the glass will flex beyond the breaking point of the carbon. Glass is also a lot cheaper. I put a 1 inch strip of 2.5 oz glass on the LE to solve the midair problems. -- Dick Barker Seattle, WA - The Old Fart Glider Flyer - http://www.eskimo.com/~dickb/UpLink.html >Whats the reccomended layup for a HLG wing.
