zero you will have altered the Ailerons.
Its just like the stalls when I first started demo them I always got a wing drop.
A year later and gawd only knows how many stall demos the aircraft never dropped a wing when I demo'd them.
I couldn't remember putting any inputs in when I started and they still dropped a wing when the student was doing them in the same aircraft.
As for the flat spin been there and done it as well.
