Hi SoCalSal
In the second sentence of your first post you state that if the upper wing has a negative incidence (and the low wing is at zero) the top wing will stall first. I see it as stalling last. Am I mixed up?
Hi "O" AOI is still more than negitive AOI that is why the top wing would stall first if it is set at a AOI value less then the bottom.
Airfoils always stall at some positive AoA. For example lets say 16 degrees. If the bottom wing is at 16 degrees it is in stall. If the upper wing is set at -1 AOI relative to the lower wing it is only at 15 degrees and has NOT stalled yet.
