Hello,

This is the first time i am using APM. After calibrating accelerometer and compass yaw value must be nearer to zero. but it is showing 298 deg.
What can be the possible reason? My compass data is ( 257, 20, 7 ).

Thank you.

Magnetometer is facing wrong direction.

Sir , you are using mission planner , please use apm planner instead of it .

Sir I am using on board compass. And the quad is on the ground.

I have tried that too.  Should i calibrate both the sensor again?

Ok , do one thing , go to initial setup , compass , in the middle there would be a option for rotation , set it to 180 degree yaw . Also if you are using external compass , set it to 180 roll+yaw and it should work fine

If you have not calibrated calibrate it again. But its better to use a board with external compass

Thank you sir.
do you think it'ld be the the reason for flipping over of the quad?
