If you stall a small Cessna with landing flap and some power, especially from a right hand turn, you WILL roll off to the left, probably quicker than you think!
This is not a miss rigging, and I have seen this on many individual aircraft.
It is a great shame that some instructors only teach up to the approach to the stall.
Stalls in themeselves are not dangerous, I like to show students what happens when you DONT recover straight away!
