I'll need to find figure C on sheet 2.



Draw a line on the plans from the center of the leading edge to the center of the trailing edge. Measure down to the end points to the center of thrust. Use the difference divided by root length and take the arctan of that number, that is the wing incidence as measured by the Robart incidence meter. Based on the drawing A and B being equal has nothing to do with the setting the wing incidence with a Robart incidence meter.

Likewise the front wing spar mounting point. Locked at the 'A' dimension........ Wing incidence cannot be adjusted unless I differ from plans.
