Compass error when flying in one direction only

[fredz]

I get constant compass errors (like every second) when flyin eastwards at high speeds. Not at lower speeds, and not in any other direction. The wind (very moderate) was coming from the south.
I recalibrated many times, but still the same.
What could this be/how could I solve this? Thanks

Let me guess, Atti Mode?

Any mode

Now that's interesting

Anxious to watch this thread, one way or the other, some good info will be learned.

Have you uploaded flight logs to healthydrones.com for analysis?

If you retrieve the .DAT from one of these flights I think there is a good chance the cause can be determined. Could you also provide a .DAT for a flight where the AC is brought to, say, 20 meters and then rotated 3 times at about 5 to 10 secs per 360 degrees. I'd be looking for a difference in Yaw determined by the FC and Yaw determined by the magnetometers.
