You are into part of the speed learning curve. The sharp trailing edge reduces drag. The sharper the leading edge, the more drag is reduced. However, when you create a sharp leading edge, you also create some additional problems such as a high speed during landing, something most of us try to avoid. There are compromise in the design of airfoils and related airframes. If there is another dust or similar wing in your club, watch how the thing flys and how its launched. They are fairly hot landing ships, so some care is needed. One of the guys in our club refuses to hand launch these things, he uses a pvc pipe launcher, a simple 3/4" pipe each side of the wing set on a 45% angle on the ground and a foot push release. Have seen several on line in the past. I have a scar on the top of my head from hand launching a wild one's first out of trim flight. Care is in order here. ENJOY Rever bro 119
