Thanks Mike: So if I use maybe the rearward 3-4" of the canopy surface and set that level, then I should be able to set the stab at zero and wing at .5 off of that. That should simplify things quite a bit. I am putting in a new stab that I had cut that is a fixed one piece stab to save the weight of the stab adj and tube, so I want to be sure I'm at zero.
