Did you see the 1:37 minute of the video?
The two devices do the same
FW 1.7.1.5

I watched the video.  What happened after that.  The video stopped.  Have you downloaded the DAT file and requested a review?

I had to release the phone and retrieve the station
What I do not get is a stable Dron in Yaw,And I'm testing with two different multicopters
And the two A3 behave the same

That plate one day after 30 min was turned to spin on its axis alone

Have you modified the configuration parameters for your X8 or are you using default?

I have flown it by default
rising gains and attitude,  well, but the processor is locked
falling gains and attitude,very slow
Similarly, the problem with the yaw persists
I'm trying a quad with an octo
