f5soh,

Do you mean Firmware mod in the radio or FC?

If it is in the FC, do you have any beta that I can use?

Thanks

I talk about FC firmware of course.
There is no beta to debug what you want.

Thanks Though.

I will check the Receiver antenna and the Tx to see is there is something wrong with them. I also will do a test with the GPS and RTB option on, then turn the radio off to double check that fail save work.

So Thinking on this, it clould be the Pawer wire:

Of course if receiver is not powered the signal stops and failsafe occurs.
