Blackbox recording does not match drone movement (pitch noise)

[tomstell]

Hello,

I have a very strange issue. I have been reading my blackbox data and they do not match the movement. Specifically, when I do a flip the blackbox records that I actually do a flip followed by a roll. I can actually hear that there is something wrong during the flight as the drone does a loud, strange sound. Also, when I look at the blackbox data it shows a great amount of noise for pitch but the roll scale is fine. I have checked this from gyro scale and D-term and they both show that there is a lot of pitch noise.

I am also attaching the blackbox recording if you would like to have a look.

Thanks for your help!
Thomas.
