It makes no real gain in straight line performance i guess, it's effects are noticeable in yaw.
Thanks for the insight.
When I first started looking at my FW photos again I noticed that many EP " notches"did line up with the upper elements. But then as I looked further I found that this was not the case in most of the pictures I have.
Would the same principle be in effect on this wing even though it doesn't line up with the upper elements?
I really don't know, but it may not have to be exactly aligned. I think the wind tunnel or CFD tests dictate how and where the notch is in each case.
