when u are in cockpit u don't see the tracers? only when u fly with the guncam on? wouldn't be much more realistic looking at the spinning tracers that hit the plane?

No, that's not what I am saying. I am saying that the vibration of the gun camera is what causes the tracers to have the zig zag effect. A pilot flying the plane would see the tracers, but they would not be squiggly to his eye because he is not looking through a guncam.
