There has definitely been a significant change to some planes. I can’t work out whether it is a global flight model change affecting some planes more than others, or individual nerfs.
Of the planes I have, I have found (on PC):
IL series in Berlin campaign are heavily affected to the point of being basically useless for their primary role of ground attack - cannot pull out of even shallow attack runs, and now have massive yaw which they didn’t previously (worse even than the FW was)
109 Series appear significantly affected as well, perhaps not as much as IL series, but still very noticeable. FW seems largely unaffected - possibly less yaw? I haven’t flown FW that much given how terrible the flight model was for it (particularly the absurd yaw)
La Series in Berlin are affected to a lesser extent, but still noticeable.
Yak seems minimally affected, but I need to retest that.
In Normandy Campaign:
Ju188 seems largely unaffected?
FW190 seems improved?
P47 series seems somewhat affected, slightly more sluggish than usual.
Haven’t tested the Lightnings.
Moscow:
IL seems largely unaffected, which is weird given how broken the IL is in Berlin now.
Haven’t tested SBM or Pe.
Lagg (premium) badly affected, cannot be used in intended role of ground attack
Haven’t tested Yak
I haven’t tested anything in Tunisia specifically.
The biggest issue I have found is that the planes affected now cannot pull up out of even shallow, low speed approaches. They are basically a brick when you point them at the ground. I wonder if it is somehow related to the addition of working airbrakes??
On the upside, I love the new audio, and the ability to actually look behind you, and there appears to have been a fix to the underperforming 20mm cannons. Maybe one day we will even get the ability to set our convergence as well!
