DIRECT ANSWER
Start with one connected device, bind steering and throttles, check neutral, then reconnect extra peripherals one at a time.
Clean setup
A controlled setup makes duplicate axes visible.
- Disconnect unused gamepads, wheels, quadrants, and pedals
- Restart the game
- Bind rudder and throttle to one device
- Check that every axis rests at neutral
- Add other devices one at a time
- Save a vessel-specific profile if available
Deadzone status
Demo Revision 1320 added rudder deadzone support for HOTAS and controller setups. Apply only enough deadzone to stop drift; large values make fine steering harder.
