So I know that the pixhawk has a safety where if the main CPU fails (and by that I assume the code), the 2nd lesser CPU can bridge the first 8 RC channels, which in the case of a plane will let you fly in manual mode even though the autopilot is dead.
I was just curious: when can this save me?
Arduplane code bug, crash/reboot?
Hardware failure? If so, which one(s)?
Arducopter doesn't have this feature obviously, so I'm just wondering how often this pixhawk feature comes in handy, if ever?
And I'm asking because my new plane is vtail and it's complicated if both my controller and the arduplane do vtail mixing...

seems to say that pixhawk failures are extremely rare and that I should not worry too much about relying on that passthrough feature, or losing it if I have the pixhawk handle mixing of critical channels (flaperon and vtail)
