FS_GCS_ENABLE question

How do I get this to work with Solo? I don’t understand the RC_OVERRIDE part and where that is set. I want to enable autonomous mission in Tower but need to know if simply setting the FS_GCS_ENABLE parameter to 2 will get the job done when I lose communication from my controller to Solo. I cannot find the answer to this anywhere. Please post if you’ve ever fine this or know if the RC_OVERRIDE thing is necessary.
