Vince, I am not conVinced yet (LOL)

After reading the posts there is still one question left and Bob will help you with answerring.

What is in your explanation an incidence of – 0.3 degrees of the stab, situation a or b.
The picture is NOT scaled !!!!

For me a negative incidence is a and positive incidence is b.
So a negative incidence of -0.3 of the stab and a positive incidence of the wing of 0.3 degrees results in an decalage of 0 degrees.
(For me a positive trim of the stab results in a nose up ATTITUDE of the plane.)

When b is your negative incidence of -0,3 degrees (not scaled!!!!) then -0,3 degrees of stab and + 0,3 of the wing results in a decalage of 0,6 degrees.
