Took the quad out to show the neighbor. Turned in on and it stayed stuck on Warming Up. Sat there forever too. Camera worked, had gimbal control etc. There was a message that came up that said "Slave requests gimbal controls" That was a new one. Went back home, downgraded and then upgraded again, still the same. RC link light is green. Took it out a couple of days ago after the new upgrade to 1.5, now, not so much. Any thoughts out there?
