Take myself [or any experienced instructor] for a fly in a cessna or piper single and they will show you that you are on the wrong track.
I would not suggest doing it at 500'
Agreed, I still have fond memories of doing a pre-test recommendation flight and asking the student to show me a stall in the landing configuration. At the point of stall the student recovered initially with reduction in back pressure whilst simultaneously increasing to full throttle and applying rudder. However rudder was applied in the incorrect sense, and to the stop. Needless to say, it was a perfect demonstration of how the rudder is still effective whilst at low airspeed in the slipstream, and showed us one of the more unusual ways to enter into an inverted spin.
Not something I would have walked away from if commenced at 500'.
