Rabbit Buzzer Affects The Compass

Here's a short video showing the affect the buzzer can have on the compass, It might explain why some people have problems when calibrating the compass

Looks to me like you just need to extend the buzzer wires and move it out on to one of the arms away from the flight controller

That would be the best cure for this problem, but mine is on short leads and my compass seems to be working fine, maybe I should carry out the test to see if it is affecting mine, the thing is I always think if its not broken don't mend it  ::)
