Do the following:
Take a plane up, deactivate combat trim and trim the bird lets say for 300 mph. Than fly a turn. U will see that the ball will move.
Ok, I tried it. I took a P51, 75% fuel, to 10k. Got to 300 mph, and made a left turn. In this case the ball does indeed shift to the left, but only in response to back pressure on the stick. If you bank to the left and do not pull back on the stick, the ball will stay centered.
As I noted in my last post, if you make a RIGHT hand turn, the ball doesn't drop to the inside to indicate slip, it will stay centered unless you pull back on the stick, at which point it will go to the LEFT, as in a left hand turn, indicating a skid rather than slip.
I next took a P-38. Whether you go left or right, the ball stays centered, and does not react to pressure on the stick. I believe this is because the FM takes into account the counter-rotating props, which cancel out gyroscopic precession.
Now we may be seeing the same thing but calling it different things. When I say the ball doesn't move, I mean in any significant amount. It does move some, but in any of the turns I made, it never got outside of the two centering lines, unless I moved the stick back.
In MS Flight Sim and Combat Sim, the ball will fall well outside the centering lines whenever you put the plane into a left or right bank, and you need to apply left rudder in a left turn, and right rudder in a right turn to coordinate the turns.
