I have trouble figuring out how to setup the "zoom view". A4-E has a binding for "zoom view slew" and when bound to axis, you can zoom in/out and when you let go, it will stay. However, for example F-86 only has "zoom view" and when I bind it to Z-axis, I have to hold right-trigger or left-trigger to hold zoom level, when I let go, it gets to some value in the middle. Am I missing something or is this the way people use it?
