I was on a job 2 days ago with 2 Inspires. I flew both on Saturday with no problems. Cleaned, checked and charged them Saturday night for shooting on Sunday. Got up Sunday morning and went to start one, it came out of transport mode ok, but wouldn't initialize and had no flashing RGB light. It just beeps. See video. I thought, that's ok, I'll just grab the backup Inspire and use that ... um ... no, the back up is doing exactly the same thing ! The only common denominator I can think of that may have effected both Inspires is environmental. We were filming an offroad race and it was very dusty. Another factor could be vibration. We were traveling between locations in a chase vehicle at high speed on very rough roads, but the Inspires were in their cases and we had 5 other cameras on board that were all ok. I have run out of ideas and confidence in DJI, I guess they are off to China ... AGAIN !!!
