I am seeing a problem when I try to calibrate my compass. Using an iPad I launched the DJI Pilot app and select compass calibration. The rear lights on the Phantom 3 turn yellow. I hold the Phantom 3 horizontal and rotate it counter-clockwise. The rear lights turn green. I then point the Phantom 3 nose towards the ground and again rotate the unit counter-clockwise. Instead of getting the rear lights flashing green rapidly, I get the rear lights flashing green slowly and the status bar on my iPad says that it is safe to fly. The problem is that if I try to fly it, the Phantome 3 goes into a wide circle just after lift-off and I can't control it. My understanding is that this is a result of a bad compass calibration. I've done this in many different locations (except I don't try to fly it) and I never get the rapidly flashing green lights. Am I missing something or am I doing something wrong??

are you wearing any jewelry or anything metal on your person ?

are you calibrating in an open area away from any metal ?

What is your MOD value after you calibrate the compass?

Try rotating your whole body and not just the phantom. So, once round horizontal, once round vertical.

No there is no metal around me or on me. I am in the middle of  a field with no trees or any metal objects nearby.

I will need to check that the next time that I try to calibrate the compass. What should it be?

I am rotating my whole body and not just the phantom. I wonder why the horizontal works as it should but the vertical does not.

I said once round but keep circling until you get the light change. I did one this a.m. and it took more than one rotation on the downward spin. My compass usually reads between 1400-1500.

sure that you do not have to calibrate it nose up ? i mean with the camera side up ?

per the manual's Indicator Light Description, they are supposed to flash green slowly when "safe to fly GPS". Nowhere in the manual's description does it address or have "green lights flashing rapidly". It wil only flash rapidly for a brief moment when home point has been has been recorded.

That's was what I was wondering. However, when you look at the DJI Tutorial video "How to Fly" it shows the light flashing rapidly after the calibration with the nose down. I am curious if any or everyone has the same experience as I do where you never see the rapid flashing of the lights when you complete the calibration.

There was a cell phone nearby that was being used. And after it was turned off the Phantom did fly normally but I still never got the rapidly flashing green lights at the end of the compass calibration.

you know I'm not sure i will do one tomorrow and check, its one of those things i do but but not takes much notice of .

Also, make sure to be away from concrete. The rebar can cause a bad compass calibration
