That doesn't mean it was accurate or correct before.
I'm not talking 450mph bnz from the stratosphere picks here, I'm talking dogfights, but I mean dogfights where you're paying attention to your speed and flying smart (trying to stay above 160mph) and so forth.
That in no way means I'm timid, and am afraid to use flaps.
Fact is flaps still work. To me they work almost like the flaps of old, but with more drag (more realistic, the US flaps pre 2.07 were total BS and almost everybody knew it). It's only the last notch that has major problems.
As for a little instability in the 38: I didn't notice any. I was pulling through stalls, through loops, I was pulling pretty tightly. I never once snap-stalled, or spun out, hell I haven't even gotten into the spin-O-death lately. I'm by no means a gentle soul on the stick, either.
Perhaps your stick is far too sensitive. In ANY plane if you pull up hard enough you can instantly spin/stall yourself out. This is true of most planes with great elevator authority, and the 38 fits into that category.
Perhaps my experience in the 190s has taught me to use the elevator gently, because I've not had any of the problems the folks here have been mentioning.
Your mileage may vary.
