Hello,

I have a problem I bought the kk 2.1.5 board already with the FW 1.19s Pro, and when I do the accelerometer calibration it always calibrates with

ACC x: 512 OK
ACC y: 512 OK
ACC z: 512 OK

In the sensor test menu, I always show the result 512 for all calibrations.
And when I try to fly with the drone it doesn't stay stable, it always tends to the right and turns upside down.
