Now imagine a far draggier powered a/c in the same situation - I'd guess that at the top of the push over the airspeed might be less than VS (but reduced G so still flying), and maybe 5+ seconds to regain flying speed.
Take a PA28-181 climbing out at the recommended 76kias at normal attitude.
Are you saying that the airspeed will drop from 76 to less than 55 knots (VS1 IIRC) in an instant?
I don't think so.
The effect of the dragging prop disc will be noticeable and the aircraft will pitch down sharply to regain its trimmed speed (which also is best glide), but it won't stop flying, unless mishandled.
The main threat will be the very high RoD and the limited options for forced landing from low altitude.
Gliders and SEPs are different beasts.
