Please see my logs. What happened?

[Tengo]

My drone hung up a bit in the air, began to prowl and flew to China, but crash in the forest.
In the log I see many errors about compass.

What to do in this situation - how to take control? And how to avoid this in the future?

Thx all.
It is my first post

My log is here Microsoft OneDrive

Did you take off from the roof of a building?

@Tengo

And how to avoid this in the future?

Before taking off next time, you should make sure the compass is not being affected by nearby magnetic metal objects. See more details here.
