Well, actually, nose bounce isn't "normal" being that you should accept the fact that it can't be resolved. It IS normal to the extent that the planes are modeled for realism. Basic concept being that "for every action there is an equal and opposite reaction" Beat on a plane in a left side skid will in effect make it swing back to the right violently (Nose bounce). Easy inputs gets easy "reactions" to that input. Everyone has their own style of man-handling a stick, so you really can't get advise on what to set them at. I am, for one, a person the really works a stick hard (ok, this isn't sounding kosher) and because of this fact, I am really having a very difficult time elliminating the nose bounce. Particularly in the "fine tuning" my aim just before shooting. Nose bounce can also occur if your stick's center position is wearing out..you can tell this because you nose will skid side to side, or up and down even when you are not touching the controls. If you stick isn't TOO worn out, you can eliminate this by raising the "dead band" for the particular axis in the AH2 joystick setup as well.
I did, however, find last night that the A6M (zeke) is very forgiving and seems to like rough handling. It seems to take to man-handling very well. Unfortuantely, from what I've been reading, this plane has limited options against a lot of later war birds.
