I have found with both the yoke and the throttle that it’s better to select the input on screen rather than try to move it in real life. Usually when I try to get it to scan for an input several things get triggered at once. Assuming you’ve got everything plugged in correctly and set to XBOX mode (and set to throttle quadrant 1 using the toggle switch on the back of the throttle), you can use the following inputs to map to what you want. These come courtesy of another post on the forums by user Nixon Redgrave which has proven an invaluable resource to me in using this peripheral.
