I don't know why the way planes behave changed between 2.15 and 2.2, but now I have to tell that I find them completly broken.
In 2.15 everything wasn't perfect (landing without damage was very hard, even for an experienced pilot) but the global feeling was realistic.
Now the planes are just like Tie fighters in space. Too fast, far too manoeuvrable, and absolutely impossible to stall. I tried the spitfire IX once, it just took off after 3 meter of runway just like it had boosters.
I also saw a Me109 turning 270° with a few meters radius (which is impossible with most of the planes, and especially with that one), and a Ju87 diving right and left, so that the bofors just below couldn't even follow its movement !
Please, bring the planes back as they were, flying is no more a pleasure now.
