Adding FIP Plugin to X-Plane is very simple:
Download the “X Plane Plug-in” from Logitech’s support page — No worry even if you are still using the previous Saitek drivers and not the recently renamed Logitech drivers.
Run the downloaded file to install the Plug-in — A new folder called “XSaitekProFlight” will be added to the “\X-Plane 11\Resources\plugins” folder automatically.
That’s all you need and you are good to fly with the default gauges in X-Plane.
After the installation process mentioned above, make a copy of the “XSaitekProFlight” folder and call it “XSaitekProFlight_Backup” (or whatever you like) in the same (or any) directory.
Open Control Panel and select to uninstall “X-Plane Plugin”
Rename the “XSaitekProFlight_Backup” folder back to “XSaitekProFlight”
Now the FIP X-Plane plugin folder is independent from the installer.
You can regularly backup this folder with your own gauge contents included, and paste it back to the “\X-Plane 11\Resources\plugins” folder whenever needed without going thru the installation process again.
This not only helps prevent unnecessary and unnoticed alterations to the gauges, but is also good for future X-Plane setup whether it is going to be a fresh install or an update restore.
