The failsafe itself wasn't particularly surprising -- I'm using a crossfire micro RX with an immortal T antenna with vertical polarization.  I was running the crossfire TX at 100mW and rolled the plane.  This caused the signal to drop considerably, taking LQ with it, and then FS kicked in.\r\n\r\nFailsafe leveled the plane and started flying it back.\r\n\r\nExpected:\r\n\r\nSignal to resume and the FC to let me take over again.\r\n\r\nActual:\r\n\r\nFC remained in failsafe for just over three minutes before allowing me to take over again.\r\n\r\nIt appears that the FC was not seeing CRSF for those three minutes.  RSSI on the OSD was stuck at 51 and then started moving around again.  I was able to take over and continue flying my plane for a bit.\r\n\r\nNote that the crossfire signal itself was fine.  Except  for the incident that actually induced failsafe, my signal was fine for the majority of the time I was stuck in failsafe.  You can see approximately how this looked in the following image (taken from recorded telemetry on my Taranis).\r\n\r\n<img width=\"1119\" alt=\"companion_log_viewer\" src=\"https://user-images.githubusercontent.com/1779/43998512-11fddaf0-9dac-11e8-80ce-65e6ea3a13d6.png\">\r\n\r\nUnfortunately, I don't have any blackbox logging for this plane.  This has happened more than once, though (the first time it happened, it took even longer to give me back control).  I'm wondering if, perhaps, there's some CPU starvation or something that's preventing CRSF and FS from coexisting peacefully."},"comment":{"url":"https://api.github.com/repos/iNavFlight/inav/issues/comments/412318533","html_url":"https://github.com/iNavFlight/inav/issues/3729#issuecomment-412318533","issue_url":"https://api.github.com/repos/iNavFlight/inav/issues/3729","id":412318533,"node_id":"MDEyOklzc3VlQ29tbWVudDQxMjMxODUzMw==","user":{"login":"dustin","id":1779,"node_id":"MDQ6VXNlcjE3Nzk=","avatar_url":"https://avatars0.githubusercontent.com/u/1779?v=4","gravatar_id":"","url":"https://api.github.com/users/dustin","html_url":"https://github.com/dustin","followers_url":"https://api.github.com/users/dustin/followers","following_url":"https://api.github.com/users/dustin/following{/other_user}","gists_url":"https://api.github.com/users/dustin/gists{/gist_id}","starred_url":"https://api.github.com/users/dustin/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dustin/subscriptions","organizations_url":"https://api.github.com/users/dustin/orgs","repos_url":"https://api.github.com/users/dustin/repos","events_url":"https://api.github.com/users/dustin/events{/privacy}","received_events_url":"https://api.github.com/users/dustin/received_events","type":"User","site_admin":false},"created_at":"2018-08-12T04:48:24Z","updated_at":"2018-08-12T04:48:24Z","author_association":"NONE","body":"It's worth noting that the yellow line in that image is distance.
