Pixhawk GCS fail doesn't work

It’s turned on but never goes into RTL even after shutting down the gcs radio for one minute. Anything that effects this not coming on e.g. going into FS? I have the param set to 1. Almost lost my $2000 quad I should would like to get this working. Thanks

What tx do you have? I have a Taranis. It needs to be set up for ‘no pulses’ (I think my 9XR did too) and if you’re using a ‘x’ series rx (may affect other Frsky’s, don’t know), it needs to be put in FS mode.

Anyway, that’s what I did.

Thanks I did get it working.
