Krayzc - I have a Robart incidence meter. Used with no instructions. I'll check around for some instructions.

Basic question: I'm guessing that an incidence meter provides me a measurement, in degrees, between two lines. From your post I gather that it would be helpful to know that measurement between the wing chord and some line, the horizontal stab and some line and the engine thrust line and some line. What is the "some line" that I'm comparing the wing chord, stab chord and thrust line with? I'm looking at the plans as I'm typing this reply. They recommend a 2 degree down thrust (or -2 degree), a +1/2 degree incidence angle for the wing and no angle for the stab. There is no reference line on the plans to be used to establish any of the angles. Can ya help me how to establish the reference line?
