A few weeks ago I upgraded my firmware and now my Radio Channel Quality section under the Aircraft Status menu flashes from good to poor every few seconds. also my nav lights on the drone flash red every 4th time. I can still fly the drone out to 1400ft before I lose signal but I did notice the signal looked to drop and comeback. I have tried rolling back the firmware to the P3C_FW_V01.06.0080.bin with no luck. anybody else had this issue?
