Greg,
You are welcome.

To double check the values and my own explanations I did take a look for a better example of the original Intruder drawings. I could not read the characters in the first examples.
Did find them and made a combined picture of what is noted about stab and wing incidence, both zero degrees.

Also did read the construction article of the original Intruder and for me it is clear, 0 – 0 degrees is the basic design requirement of the wing and stab and are not adjustable.

If the World Intruder does need 0.6 degrees decalage to perform, then we have to speak about a different (modern?) plane in my opinion.

First flights? Of course we are all interested, so maybe you want to let us know in the future what your experiences are.
