Michael, so this is happening to you with PPM radio type? That's the first report I've seen, so far it's been serial input types only. I've never seen that in any of my logs, and I've been using > r100 for months. But I understand the Spektrum issue doesn't affect everyone either... mystery deepens
It would be great to identify what causes the quality to drop, and/or be able to recreate it on demand. At this point neither Bill (last I heard) nor myself can repro the issue.
AQ failsafe won't engage until the radio_quality drops below 0.1 plus a 1 second delay after that. The problem is more than cosmetic but by itself shouldn't cause a loss of control (not sure I'd still fly with it like this myself though).
