I've had a lot of truble with my copter. But now i've got simple mode working (more or less).
It works fine when I'm flying back and fourth facing the same direction, even for a long time. But if i spin the copter around a couple of times it looses its bearing by as mutch as 45 degrees. Any ideas what might cause this??
I'm flying the new beta.38 standard arducopter frame. magnetometer is mounted the recommended way
