RC connection delay r9sx and pixhawk

Hello. I have a large flying wing that I’m tuning. Normally when I unplug and replug the battery to the pixhawk 6c to reboot and everything comes back to life fairly quickly. The radio connect to the RX within a couple of seconds. But now all of a sudden after over 100 normal reboots when I unplug and replug sometimes it takes 30 seconds or longer after control surfaces star for the RC to connect.

I can leave it on for hours and it does not ever seem to disconnect, but I’m concerned about it.

I have read a few instances of people having GPS act in a similar manner with 6c.

I would be interested in people thoughts about this.

Also, I should mention if it’s off for a long period of time the first time I plug in it connects right away.

Thanks in advance
