the whole problem was or is that the wing saddle did not match the airfoil, on this aircraft, by manufacturer, so i went back to the basics and leveled the fuse at the thrust line, because there is no datum line, from front to aft , its fine, then i measured
up from the floor at each wingtip , first the center of the leading edge , than the trailing
edge, the numbers came out close to the same at these points on the left and right tips. IF the leading edge measurements were lower than the trailing edge numbers,
than i would have had neg incidence. I probably will ck it with an incidence meter.
