1. Compass = FAIL - Large change in mag_field (50.37%)
    Max mag field length (551.81) > recommended (550.00)
    On checking the auto analysis of log files I am facing the compass fail error.
    For the compass I choose the PX4 module and calibrated the quadcopter many times. Many time “Pre-Compass inconsistent” error is coming before flying only which is much higher in the lab (testing area) and less on the flying field.
    For this log detail particularly, there was no issue of “Pre-Compass inconsistent” on the ground but log showed compass failed after flying.
    All the possible calibration procedure has been followed.
    I am not able to understand the problem. Kindly, help me with the issue.

  2. Yaw behavior speed issue
    I wanted to check the yaw behavior for my quadcopter. The quad followed the Yaw behavior but the speed of heading change was too high.
    Need to control the yaw behavior speed. Please, help me with the issue.

  3. Heading changing issue
    My quad took take-off at a heading of 91o but landed with a heading of 108o. Not able to solve the problem. Kindly, help me with the issue.
