I found a post in the Turtle Beach Discord channel that says that in MSFS on Xbox, some of the buttons are mislabeled. Here’s the list:
B1 - JOYSTICK Button 1
B2 - JOYSTICK Button 2
B3 - JOYSTICK Button 3
B4 - JOYSTICK Button 4
B5 - JOYSTICK Button 5
B6 - JOYSTICK Button 6
B7 - JOYSTICK Button 20
B8 - JOYSTICK Button 21
B9 - JOYSTICK Button 9
B10 - JOYSTICK Button 10
B11 - JOYSTICK Button 22
B12 - JOYSTICK Button 23
B16 - JOYSTICK Button 16
B17 - JOYSTICK Button 17
B18 - JOYSTICK Button 18
Trim Wheel click - JOYSTICK Button 15
H1 Left - JOYSTICK Pov Left
H1 Right - JOYSTICK Pov Right
H1 Up - JOYSTICK Pov Up
H1 Down - JOYSTICK Pov Down
H2 Up - JOYSTICK L-AXIS 7+
H2 Down - JOYSTICK L-AXIS 7-
H2 Right - JOYSTICK L-AXIS 6+
H2 Left - JOYSTICK L-AXIS 6-
Left Throttle - JOYSTICK L-AXIS 1
Right Throttle - JOYSTICK L-AXIS 5
Joystick Up/Down - JOYSTICK L-AXIS 3
Joystick Left/Right - JOYSTICK L-AXIS 4
Joystick Twist - JOYSTICK L-AXIS 2
Trim Wheel as Axis - JOYSTICK L-AXIS 8
Trim Wheel as Button Up - JOYSTICK Button 24
Trim Wheel as Button Down - JOYSTICK Button 25
On PC, this list is different. The buttons are labeled correctly. But not only that, the default configuration for the V1 stick in MSFS on Xbox uses the PC mapping, which means that I need to fix it manually.
This is CLEARLY a bug in the Xbox version of MSFS, and it’s a really dumb one too.
