I'm going to flat out say there are things alot "gamier" in the game you could worry about Anax. Such as the constant use of late-war British and Russian point-interceptors for *everything*...
I'm also going say that if you can't make the shot without raising your head in most planes, you probably can't make it with raising your head.
I use a little red cross for a mouse cursor. Even in Fw-190s, where you can only raise your head position 2 millimeters or so, not so much to see over the nose but because the way the lighting is modeled on the reflector glass gives me the %@%$@%Y%@%$
just trying to SEE the other plane sometimes. I don't consider being able to see the other guy's fluff'ng wingline and whether he's inverted or not "cheating".
