Makes me think of the C172 "my" flying school used for introducing us to stalling - stalled left. It needed a bit more than full right rudder to stall straight - I was glad I had flown a lot of RC, felt it when lifting it off, and asked the instructor what kind of stalls we were to perform. "What kind of stalls - what do you mean?".
Just traight ahead, I asked. "Would do nicely", he answered, so I knew that he knew, but knew too that he didn't know that I knew..
I managed to perform three almost straight ahead stalls before he noticed the rudder foot. Then we did some without rudder - felt to me as if a church fell on left wing, with a 60 - 70 degrees wing drop. He asked about spinning, but I decided against it, I would rather be sure we could get it ot of spin too.
It was later sold and had a "landing incident" shortly after.
What I would like to know is, is it normal for flying schools to have something bad-mannered for "waking up people"?
