Failsafe with Hitec Aurora?

[Jesper]

I have set up the switch failsafe, without any problems. It switches between A - FS - M.
But I would like to set up my Hitec Aurora to make the Naza go to failsafe if the A9 loses signal, has a brown out or gets turned off!
I know how I do it, but I see that there ain't a way to make one channel go to failsafe. I have to setup my radio to a point where the RX stores the setup.
Do I set it up at no throttle, sticks centered, failsafe switch set to failsafe or not, I don't have a clue to what settings I store to failsafe.

Any help would be nice

Throttle above 10% but less than 50%.
Switch in "Failsafe".
Rest of positions not important.
