I used to do a demo for students (in a Piper Warrior) of a full power climbing right turn.. I'd chat to them as the speed bled off - and then point out that I now had full right aileron as the aircraft rolled left in the stall (outer wing has the higher angle of attack in the climbing turn).
The demo served to point out:
1. How "easy" it is to enter an inadvertant stall when you aren't paying attention.
2. How a stall is recongnised as basically "any time the aircraft doesn't answer the controls."
3. Pushing forward on the stick is the answer to almost all of your problems.
The students were generally impressed at the roll against full opposite aileron - most never believed an aircraft would do that (training aircraft being so docile.)
