I am a little perplexed.
What has happened to the basic law of flight:
Attitude.
Power.
Trim.
Point the aircraft at zero pitch attitude,
apply cruise power
unload any stick force (trim)
and no matter what a cb throws at you it cannot sustain an over speed nor an under speed.
Using the standard practice of pitch + power to maintain safe flight does not work if the aircraft is ALREADY stalled, which was the case here.
