Got my new P4P yesterday, went ahead with all calibrations, but noticed last part of compas cal. was different, on the side instead of down, it was much harder to turn the whole thing around in my hands due to gimbal and legs, also had trouble getting the last part green, and felt i couldnt do it properly due to clumpsy movements.
Why this?

Why were you calibrating the compass?    Sounds like you didn't read the manual?  Look at p57

Labroides is right no need for calibration of compass or IMU on these machines unless prompted , if you want calibrate your camera gimbal if it's off Centre, but if it's ok no need,

Cause i dont live in China, but in Norway, and i want a true north.
This is called Magnetic declination, you guys can read more about it here:
https://en.wikipedia.org/wiki/Magnetic_declination

Manual p57 was what i was referring to, the illustration there are different from the one the app displays.
So, which way is the correct, nose down, or nose on the side?

Any other questions guys, just shoot.

Go to page 57 again and read the bit up at the top.

Why should i do that?

CineView Media Posted at 2016-12-30 13:13
Why should i do that?

Because your supposed to read the manual and obviously you haven't..

Obviously you cant read, or pay attention to what im asking about here.
I suggest you read up on the topic you dont know anything about.

CineView Media Posted at 2016-12-30 13:13

Because you haven't understood what the manual says at the top of page 57.
Can you see anything that says you need to calibrate the compass before you fly?

There's is no helping you , because you already know everything yourself!!!!!

Your heading compass calibration different from P3,
Answer yes you don't need to calibrate the P4Pro unless prompted if you read the Manual you would know that,

Unless the Phantom 4 has built in current magnetic declination maps, compass calibration will have no effect on establishing a true north. The calibration procedure is to establish sensor values used to work out where magnetic north is within the current magnetic environment. If the sensors values go out of expected limits, I'm sure that would trigger a compass calibration message, albeit I'd be very mindful of the environment in which the message was triggered as there may be unseen magnetic influences at ground level that would make calibration risky.

In terms of rotating the aircraft, I would hold it arms-length over a point on the ground and walk steadily around it in a circle, holding it over the same point. I realise this does not address the documentation discrepancy though...

Since both of you are so slow, her it is ONE more time;

WHICH WAY IS THE RIGHT WAY TO TURN THE AIRCRAFT ON THE LAST PART OF COMPASS CALIBRATION, THE ILLUSTRATION FROM THE MANUAL, OR THE ONE FROM THE APP?

If you still dont get it, then leave it up to someone with a larger brain capacity to answer it.

Why are you wanting to calibrate the compass when the manual specifically does not tell you to?
If you know so much more than DJI and can make up your own rules, you can work it out yourself.

You clearly mention in your opening post that you were trying to calibrate your compass, that's all I have to say about it,
Good luck and good bye..

Yes smarty pants, and i was asking if the routine was different from the P3.
You want me to make a drawing for you?

Calm down guys Compass calibration have nothing to do with declination, at least directly. It only calibrate the magnetic field sensors (there are three inside the compass chip - one per axis) allowing the computer to check what measurement value corresponds to the strongest measurable magnetic flux level (so we can determine the full scale of each sensor for the same magnetic field level). This maximizes precision and reliability of compass, but with better or worse calibration, compass will show you roughly the same direction of magnetic north. Declination is a difference between magnetic north and geographic north. To obtain declination value you only need to know your GPS position and current date, then you can calculate it using some math and World Magnetic Model dataset.

But you are completely right in one important thing - good compass calibration is essential in areas, where magnetic inclination is high. So maybe you just confused declination with inclination. Norway definitely is a country where inclination values exceeds 70 degrees. For example highest inclination is over magnetic pole, where it reaches 90 degrees - compass points directly down. And this is why you can't fly your drone near magnetic poles, because it shows no horizontal direction.

This is the third time you have personally insulted me, I think it's time for you to stop...

Thread closed. Don't be ridiculous, guys. To answer OPs question, there doesn't seem to be much of a difference. I personally always point the camera toward the floor.
