So the books often give the generally watered down Bernoulli explanation or perhaps mention a little about Newtonian downwash. It depends on which book you're reading.

I had a buddy locally that wanted to fly an electric scale SPAD XIII at "scale" (in other words super slow) speeds for his model. In his efforts to avoid AY he used a control linkage that generated only up travel in the ailerons.
Thank you for that post. You are probably right about the bias in textbooks which is unfortunate, but I can see that being the case.
I understand your comment on aspect ratio too, and it speaks to the prior point that it is a combination of a lot of things.

So let me link two of your references above...Bernoulli vs Newton and Adverse Yaw with the SPAD. I'm not trying to be smart and I know this kind of links two threads together.

It's interesting that the effort to avoid AY was to generate only UPtravel in the ailerons; and in doing so I'm sure the airplane still rolled.

But if only down aileron was used, would the airplane roll and if so who was the culprit....Newton or Bernoulli?
