Default Another stall spin

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.
