I borrowed an Astro Hog from a friend to check his incidence angle.
I first leveled the plane so the height of the stabilizer leading edge is the same as the trailing edge.
Measured at the center of the leading edge and the stabilizer in neural.
Next I measured the leading edge of the wing and the trailing edge of the wing. The leading edge is about 1/8th of an inch higher than the trailing edge. I measured the leading edge from the most forward part of the leading edge.
I will put my Hog on the jig and level the wing front to rear.
I will then level the stabilizer so the leading and trailing edges are the same height.
