3) Spin recovery becomes a bit more complicated. You
are most likely to spin when turning slowly in a thermal
with positive flap selected, in which case the first
action must be to select neutral or negative flap before
carrying out the normal spin recovery. Otherwise you
risk exceeding the flap limiting speed in the recovery
dive, which is a possible cause of several glider break-ups
and fatalities.

Be sure to read and heed the manual. In the ASW 20 and ASH 26, for
example, selecting negative flap is used to halt the spin more quickly,
not just to avoid potential overspeeding for the thermalling flap
position. In those gliders, selecting negative flap may be sufficient to
stop the spin with no further action.
