Using NASA calibrated measuring equipment, I calculated the wing area of my DP edge to be 980 sq inches and the extra to be 1031 sq inches. He claims on the box, these to have 1200 sq inches wing area. Is he including the wing area of the stab?, or the imaginary wing area in the fuse?, Or the area of lift from the fuse??? This means a wing loading of approx 35+ ozs/sqft for you people putting in gas engines for a weight of 15 lbs+. Hardly a good 3d setup I think. I dont get this. When you describe w area you are talking about the wing providing lift. Does this mean his big edge is really going to have a w area of 1500 ??????
