I'm getting this too, if I turn my Hexa to North (0 degrees) it appears to 
accumulate an error back to 200ish degrees, turning the Hexa again to South 
(180 deg) doesn't appear to have the same issue, but does appear to accumulate 
an error at a slower rate.

I don't believe that there is any interference issues, however I will put a 
'scope on the power rails to double check shortly.  I do have a 1000u LESR cap 
& choke between the BEC & the APM, and another choke on the GND of the xBee...

this has only become an issue I believe since 2.7.3

Please resubmit this error in the new issues list (see below) if it's still a 
problem in 2.9. Note that another user found out that a similary problem were 
caused by a faulty magnetometer.
