[size=14.6667px]I have a Phantom 2 and have had it since early 2014. Flown hundreds of flights with it and it has always performed perfectly. Mine is in NAZA mode.

[size=14.6667px]This weekend, I was flying from an overlook over a huge valley of trees for a while and when i brought it back, I noticed the rear LEDs (which normally flash green with good gps) were solid RED. I've never seen that before. The phantom itself did not seem to be acting weird but I brought it to land to be safe. A few minutes later I lifted it off with a new battery and after a while it did the same thing.

[size=14.6667px]Since then, I have tried countless times to recalibrate my compass (rotating level clockwise, then clockwise again with nose down) and each time I get rapid flashing red lights. I switch back to Phantom mode in the assistant software and tried re-calibrating and same thing (only it's rapid yellow/red/yellow/red in phantom mode). I did a advanced IMU calibration in the assistant software and it did not help. I also checked my compass mod values and, from what I've read online they seem to be in the correct range. Finally, I ended up just buying a brand new compass online and installing it...only to still have the exact same problem! Always flashing RED after calibration.

[size=14.6667px]Again, the phantom itself seems to have flown fine...but i'm scared to now.

[size=14.6667px]Any suggestions? Since I've had my phantom I've recalibrated multiple times and have never had this problem.
[size=14.6667px]Please help!!

Could you happen to provide a screenshot of your IMU and compass values from the Assistant Software?

Again...it has a new compass on the phantom and it's still blinking fast red after every time I finish calibrating it.

Just to clarify, you had not performed any foil modifications to the GPS puck, correct?

I don't know what that means so I'm assuming not.

1700 seems a little high, but maybe you are indoors.
Go out in an open field and remove watch, phone, belt etc. Redo the dance. Also check if you are not near a no fly zone.
Also check that all the toggle switches (S2, and S1) are functioning.

Could you please try QuanthonyTrang's advice and let us know if the issue still persists.

Hi Aerial Hiker!

Just wondering if you were able to figure out the problem. I am having the same issue.
