@Chad-Sweet Hi Chad, I go further and for the accelerometer calibration I have another issue.
With Rotation None, the QGC see my aircraft on left side instead of level position, and so on.
When I test to arm and take off, it see the vehicle as turn on right side and have failsafe issue.
If I put Rotation = Roll 270 is much better, and I can arm and takeoff (just simulate for now).
Still, I have two positions that are not right, aka it show the vehicle on:
left side instead of noise up
right side instead of noise down
I would really appreciate your help to indicate me the right value for the Rotation to well calibrate this sensor.
Thank you!
