Hi.

I have had my phantom for 4-5days and did about as many flights. I love it, no issues what i can see when flying. But it is my first real drone so what do i know.

Problem is i can not calibrate the IMU. I read about others who cant and have to send it back. Not to happy about that thought tho. I also read i should not calibrate it unless aircraft asks for it. But one day it might needed to.

What do you think? Is it a risk to fly with? Is there any chance there will be a firmware update that will fix this?

Thanks but i would prefer keeping my drone and use it for a while and see what happens with other who have same problem. My drone is working fine so no panic for me. I hope it will be fixed with software update. Other mods said we should not do the calibration unless app asks for it and that is the road i will take for now.

OK, if in that case, would you please export the flight data for further evaluation? please connect your aircraft to PC with assistant 2 installed and refer to the tutorial:
If it's convenient for you to send it in sometime, please let me know and I'll create a case for you.
You need click "Reply" so that i can get a remind and help you deal with it soon, thanks.

It does not matter if it flies properly, and we've reported this case, our R&D engineers is working on it and will improve it soon.
BTW, we need the flight data that you cannot calibrate the IMU if convenient, thanks.

i have the same problems, here are my flight data:
https://www.dropbox.com/s/5hzhmjyn30jv1gh/dji_p4pro.zip?dl=0

there is unstable flight behavoir too.

i already had a chat about it... got a case... CAS-354089-S0W2N3

in an other thread i read, that someone got a replacement and there was no calibration error and no loud high frequency fan noise... that shows me, that this calibration problem is a hardware problem? Maybe cause the fan vibrations near to IMU1 that disturb the calibration?

You case is a "Consultation" rather than a RMA and replacement, that's why you cannot see the progress. Please do not worry about that. We've transferred the data provided to the engineers, will let you know the result.

What is this loud high frequency fan noise you speak of? Is it from the props? This is my first phantom but i hear sometimes a sound when flying that can be described like that.

The only reason they are asking to send them back is because they want to figure out the error with units that are having the issue, We are just beta testers to DJI they always bring out products and spend more on advertisements rather than the development and the support at their company huh

There is a firmware update coming out that should fix this issue, as henryk86 has mentioned. I would recommend holding onto your unit until then. If the issue still persists, then a repair service would be needed. Should it come to that, your closest facility should be in the Netherlands. They can be contacted via support.eu@dji.com or at +31 208084412.
