In an early contest after getting the Extra, I flew it in sportsman with
around the same pulls as with the Decathlon (4.5-4.5G), and the figures were
of course a lot bigger due to the higher speed, but didn't present well. It
seems that with a high performance monoplane it takes more g to keep the
figures tight and present better.

However, I'm far from an expert, and now I fly acro for fun- it's just as
enjoyable, without the compulsion to make everything perfect. It had started
to get to be too much of an obsession, and the fun factor decreased. At this
point I figured that if I was looking for stress I could park the plane and
go back to work!

I would be interested in Patty's comments, but my guess is that looking at
the tight corners she pulls that they're at least 7G, particularly when
entered with a lot of energy.



I've never flown competition having mostly done demonstration flying in
military prop fighters, the AT6, Decathlons and the Pitts, but I agree
totally with you that 3 to 4 wouldn't present well in an Extra routine
being judged from the ground.

The problem I see with 6+ to 7 is snatch factor (no pun intended :-). At
that much positive g into the pull you are really close to alpha crit
and could easily slide the airplane deep into drag rise or into
accelerated stall from the high aoa delta (rates). In your airplane
could be done however with a steady hand :-)
Of course having a 10g spread both ways can be helpful :-)

I emailed Patty already. Don't know where she is today but she said
something a few days ago about showing her horse. She usually answers
when she gets a few moments.
We work together on a display flying workgroup. She's a great person and
is deeply invlved as I am in the human factors involved in display
flight safety issues.
If I hear back from her I'll post a ping for you.

The question as I put it to her was for her entry g profile for a single
loop during her demonstration in the 300S. I specified single maneuver
realizing her entry speed and g would be higher for a sequence starting
with a loop.
