Welcome Dave.... Sorry about your mishap.... I had the same thing
happen to my Dazzler, I've done tons of fast spins, but this one time
when I tried to pull out NADA think happened. I did back off the
throttle, but now thinking about it I think it was to minimize the
impact... I did try to roll out along with pulling out up right and
inverted, But nothing.. After bringing the plane back, a good
pilot said sometimes you just can't get clean air to pull out of spins
like that and that the best chance of a recovery is to cut the throttle
and release the sticks for a bit then slowly add some throttle and
try to recover with up elevator and or addition of ailerons....
Don't know if that works.. it never happened again, But I did
start stopping the spins to clean the air a little higher since then:-0
