I don't think it's changed. It shouldn't have. I flew one not long ago with the same guns package. I wasn't pulling maximum Gs, but I was pulling pretty hard at times. I never even got to the "stress" sound.
How much internal fuel did you have? What tanks were full?
i take 75%, but probably about 50-60% fuel once in combat is when its happend (4 times since patch). The 5th one today which made me post this thread, turned out to be me hitting a tree it...

but the other 4 wasnt due to hitting things lol.
It might just be my stick spiking, its getting a bit old!
