One thing I can't find is the direction of travel when calibrating the compass. I just calibrated the compass on my Phantom 3 Professional and turned the aircraft in a counter clockwise direction. Is this alright or must it be in a clockwise rotation? I wouldn't want to be responsible for changing the earths rotational direction and ended us all back into the stone age. Any comments would be most appreciated, thank you. Bud ps It seemed to fly ok just now but I thought I'd ask anyway.
