What I got from ZN was, with the stab at 0 the wing should be a little +
It makes sense, thats pretty much standard.
I added a bit of + to the wing of mine tonight....will hopefully fly tomorrow (weather forecast is iffy) and see how it goes. I double checked knife edge today and I have zero pitch to the belly in both directions. I do have a slight pull to the canopy but not sure what the mix is....I screwed it up in the 14 so only 1 elevator half was moving, so the % I have in there is wrong.....then canopy blew off in the 1-1/4 knife snap (BVM latch pin failed)....so that ended the evening
