* You should correct a win drop with aileron and never rudder: I was taught never to pick a wing up with aileron as you will probably stall the tip and increase the drop, hence the need to correct the drop with rudder and that you should never use the aileron in a stalled condition. That makes logical sense to me so I was happy with it.
Most modern aeroplanes have enough washout that the ailerons remain effective when the mainplane is well into what we'd recognise as a stall.
The danger at stall is not really about position of controls but about roll. In the normal flight regime, roll is stable: if you initiate a roll and then centre the ailerons, the roll stops. But in a stalled regime, roll is unstable: if you start to roll, it wants to continue to roll. And it's that that can cause the autorotation (spin) to start. Anything else that can cause a difference in AOA of the wings is a Bad Thing.
So the most important thing at stall is to avoid roll. If the wing is dropped, leave it dropped until you're out of the stall regime.
