I agree. KNOWING what a plane can do well, vs average, vs below par is just as important as who is flying it.
Little things like knowing that a zeke starts to stiffin' up at 375 TAS, or that 109's have a horrible view over the nose, or that Spitfire's do not pull out of a low speed dive well, or that the Typhoon and Tempest are greatly handicapped while rolling/turning LEFT, etc, etc, all mean something. Taking an La7, Spit16, or P51D time after time and not learning and enjoying the rest of what is available is sad, really. Flying and learning the different aircraft is what makes AH fun, at least for me.
