Exactly! You don't know if you need it! So fly it and crash or fly away to find out? Hmmn! Not my logic!
You never mentioned that you bought form a dealer right by you, so if you trust him, fine with that ! I was solidifying Photo's statement that the compass has nothing to do with the altitude you are flying at, "But" the magnetic bearing you are at ! And it does matter.
Man you are a sensitive one aren't you !
I am unhappy with my Pro, because it came with a dead ST16 battery, and I "Can't" fly it, if I could, I definitely would do a compass calibration, since it traveled 1400 miles from my home, If they even did one in California!
I really don't care if you do one or not, it's your freedom of choice, No reason to get all "chocked" up about it!
