J,
So if I read that back you say that the wing where the AOA at the tip is reduced due to the aileron being moved upwards will stall first. In this scenario the lower wing.
That is not my experience nor the way I understand the aerodynamics to work.
It is my understanding that on a conventional designed aircraft (with dihydral) due to the increased angle of attack (as a result of the relative wind over the wing and the downward aileron on this side) the high wing will stall first.
