Here is an issue I experienced in parts of downtown Cleveland (mostly near the Cuyahoga River). What would cause this to happen?

The video link below is from my flight log of the last flight with my Inspire 2 before the drone crashed. Notice the red arrow (which is the Inspire 2), how it spins around as I take off. It is like the GPS (or compass) goes backward or something. You can see my controller input in the bottom left. The Inspire 2 was replaced after this crash.


Using a brand new Inspire 2, the video link below is a flight prior to the brand new Inspire 2 going out of control. Notice how the arrow stays straight and doesn’t deviate unless I am manipulating the controls.


This final video shows the flight where the Inspire 2 started to have a fly away. I was able to grab the gimbal in mid-air before a crash happened and kill the motors. Notice the arrow spins around in a circle as I’m taking off as if everything becomes backward and uncontrollable just like the first Inspire 2 crash.


It's a fast "WTF is happening" moment as you try to move the sticks, hoping that you regain control. I never tried to throw it in ATTI mode when this happens though. I assume that is the best course of action? Then once landed, re-calibrate the compass again?

I should also note...each fly-away happened after changing batteries. I had completed a compass calibration before I took off on my initial first flight successfully. I have sets “A” through “E” in batteries and set “A” flew fine on both drones for the first flight. The 2nd set (“B”) was how each fly away started.

I wonder if it’s a firmware inconsistency on the batteries? I’ve had the same batteries since I bought the drone (circa 2017).
