I recently took my copter for a flight. I was able to takeoff smoothly but it hovers to the right and backwards. It was hard to fly back the drone since I had to go all the way to the left to bring it stable. There is no PID control implemented and my trimming is set to default.
I have attached my bin file as well so that you guys can have a better understanding.
I will check that and let you know right away. I auto analyzed my log and this is the output:

It says “Compass = FAIL - Large change in mag_field (54.22%)
Max mag field length (635.04) > recommended (550.00)”. How do I resolve this?
Yes, it was actually the trimming issue on my transmitter. But my log says “Compass = FAIL - Large change in mag_field (54.22%)
Max mag field length (635.04) > recommended (550.00)”.
