I'm not criticizing your performance, because you did well in an
emergency, but I do think that it's important not to let any readers
walk away with the idea that the way to prevent a stall is bank the
aircraft.


Stall was a poor choice of words. I used roll to control pitch. With
an undesired pitchup I think most of us would be thinking about a stall.

I was flying again today and played around a bit on a couple of flights.
The initial elevator position was closer to 1/2 up than 1/3. As the
jumpers are climbing out to exit the power is down to 10 inches or so,
airspeed is about 65kts and I trim nose up since they are moving forward
to exit. After they leave the drill is to close the door, power back up
to 18 inches and pushover for descent. With that much elevator
deflection bringing the power up causes a strong pitchup. I held the
elevator as immobile as I could and allowed it to pitchup to see what
would happen. At about 30-35 degrees of pitch it started to roll off to
the left, airspeed was below 40IAS.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.
