How to troubleshoot unwanted gameplay behavior like rudder and controls issues

There are several parameters you need to check when experiencing unwanted behavior in Microsoft Flight Simulator with one or several aircraft.

• Close Microsoft Flight Simulator
• Unplug any peripherals you do not need to use 
• Launch Microsoft Flight Simulator 
• Go to Options > General Options > Flight model
• Double-check that the Flight Model is set to "Modern" (Legacy flight model is only to be used with modded aircraft imported from FSX: SE)
• Go to Options > Controls Options
• For each peripheral plugged into the sim, toggle "Default" under your peripheral name
• Click "Apply & Save"
• Adjust the sensitivity curve of your devices in the "Sensitivity" menu.
• Finally, open "Assistance options" and customize the settings as per your convenience and skill.

If the issue stops while using the default keybinding it's likely that your instruments had a double mapping (e.g. on the joystick and on the rudder pedals for instance). To fix this issue quickly, simply rebuild a custom profile from the default mapping or use the default mapping.
