Step 1: Plug in your USB cable to the controller then to the PC.
Step 2: Turn on your Spektrum NX Radio Controller.
Step 3: Start MSFS2020 & wait for it to load.
Step 4: When MSFS2020 loads, click on (Options.) then Controller Options. Then when the (Controller Screen.) Comes up, look for your Spektrum or Other Radio Controller with USB. Once found & you see it on the device listings. You can then go and start the painful task of setting up the extra settings config for what etc channel on the Radio Controller. (It's not hard to setup/config but you will have to change a few settings never the less.) ----

After all of that is done..... It should be working as you wanted it to, to some satisfaction that it works......

Thank you for reading my Guide on how to Setup your Spektrum or other Radio Controller with USB to work with MSFS2020.
