As a thought - consider what might have happened with Bruno if he had
immediately centralised the controls without changing flap first.
Motivated by this thread, I tested all this on my last flight.
What happens in my ASW20B -- if I provoke a scenario identical to
what's seen in Bruno's video, then apply normal spin recovery while
staying in #4 flap -- is that the "snap roll" stops a little past 90
degrees, the nose drops about 20 and I am able to re-establish a
thermal turn without ever exceeding 65 kts. It isn't exactly the
stuff of horror films.
A fully developed steady state spin does reasonably call for shifting
flaps to #2 (-4 deg) to avoid over stressing things on recovery. But
recovery from an incipient spin can be made (and imo should be made)
with normal spin recovery inputs.

From the ASW 20 flight manual:
1. Recovery from spin can be easier achieved, if the
flaps are set in negative position (handle
forward).
