Altitude is off....

When I fire up my Phantom 2 vision on the ground it says its at 46 ft. Shouldn't it read 0 or 1 or 2 or something close to the ground?

Thanks,

Jeff

Yes, it should. Suggest you do a full IMU calibration to start with and see if it cures the error.

Thank you....I will run that and then take it out and fly it and see what i get. Too windy here today though.

still says i'm at 42ft after calibration. Also I have one of the original flytrex's installed and that data is all over the place too. Stating I have flown on my last flight almost 450 ft up when I never went above 50 ft.

That plus the compass calibration seems to have worked! Thank you

MSL or AGL? Not the same unless you're at sea.
