there are switches at each end of the throw. make sure all levers are centered before detection or it will see one that is triggering a switch. I have to center all my levers on my flightdeck to map switches. but if you know what they call the axis you need, manually remapping it after it initially assigns it is faster. let it find it wrong, hit the gear, unselect the incorrect one and pick the right one and save. its a PITA.
now if it would actually remember the profile per aircraft that would be great too. every time i need to get in and reselect the stick profile. even with the same name it doesn’t show the mapped control till i go off it and back to it.
