The usual thing is steel in the launch location - like a manhole cover or concrete with reinforcing.
You haven't said where you are launching from or if this happens in a variety of steel-free locations.

No I have tried in open grass area , off the boat ,beach and in back of hotel away from building been flying phantoms for a few years now never encountered this if I just ignore it take off it flies OK but it's an Atti mode after about a minute of flight it seems to come out of it and then it's fine the GPS situation is fine I have between 12 and 18 satellites locked just have constant compass air at the beginning

The other possibility is a big ring on your finger when you do the dance, cell phone, huge Mr 'T' chain on your neck, surgical titanium implant, you get the picture. I am left handed and my dive watch caused a compass error, had to remove it. The fact that it goes away after you take off indicates it is a local interference.

Just had a hip replaced to go along with knee replacement. No wonder having compass calibration issues.

Here is how I calibrate both P3 and P2, best because you can watch the lights change easily

I do it that way also but I don't wear a giant watch on my right wrist and grab the compass leg. It's a good idea to do at arms length to keep it away from body that may have metals. I once changed the way I did the dance and kept the Phantom close to my body. Calibration failed. I had a magnetic chuck in my pocket. I redid calibration at arms length and all was ok. Magnetic chuck still in pocket. I only need to flip my S1 switch 5 times to enter calibration mode. I also don't abuse the switch like I'm speed shifting. Gps to atti is all you need when flipping S1. I also don't push the rear of the quad up while it's facing me so it will try to
fly into my face or my camera.

But that is on a P2, the compass on the P3 is MUCH more sensitive than the P2's compass.

I take off from a cardboard box elevated about a foot and half above the concrete. Took care of my problem.

Titanium is non-magnetic. How would it affect a magnetic compass?

I carry 2 shoelaces with me in my bag, before i turn my quad on i put the laces on each side and give it a few turns then let go when ive set the compass menu to start. Set it on its side and do it sideways only i tie it to the legs that way. Takes a second and im not making a giant circle rotating my entire body vs a tiny one.

A compass error headed in your direction, because anywhere will eventually lead to nowhere.o_O

The point being that things that will not throw a compass affect a P2 will a P3
Ok, I get that part but why did you say it based on the posts made? I would think one should be even more careful on calibrating the P3. Not trying to be a smart *** here....just trying to understand what you meant. Unfortunately after your post it seems some just want to annoy people.

Very sensitive the P3 compass, Something i suspect and hope that will be calmed down a bit with the next version of the craft. While it shares the same compass feature as the inspire and for good reason, i am curious to see if its big brothers compass is as highly strung.
