My apology if I missed this crucial bit among all the posts in this thread but did you mention that you "re-build" the Inspire yourself at the begining?? If I knew that, it would have been the first thing to advise to check. I built many multicopters myself, all hexa and made that mistake a few times. I checked the wiring to the motors from ESC and from IMU to the to ESC but no matter how many times I checked all the wires (18 to motors and 6 to IMU) , it somehow happened to me a couple of times. As a result, on maiden flight it flipped on one side. I was so pixxxxed off...but I knew straight away what caused it. Checked all the wires again and sure enough one was crossed!!!
Anyway, good you managed to sort it out and you are able to enjoy your bird now.
