In fact, if you think about it, there would be a change in AoA as the
wings returned to their normal 1g state. The AoA increase at the tips
would be greatest and negligible at the roots. How large an increase
are we talking about? Pretty darn small. An amusing exercise though. A
friend once figured out how thick a layer of material a tire leaves on
the road, given normal wear. This seems on the same order.

Just catching up with this thread and no-one seems to have mentioned
the effect of the flexible wings. I don't have experience in the 20
but I do have a series of photos of a fatal accident that started
with a contest finish pull-up and quickly ended up in a spinning
impact with the ground. I believe that the increased angle attack
caused by the wings returning to normal deflection contributed to the
accident.

Flexible wings do NOT change their AoA while they are bending -
otherwise flutter would start immediately.
