Hi Donnie. The drifting is in GPS mode. In manual (ATTI) mode it will drift anyway with wind and a ...

And just to clarify, you are not receiving any sort of tuned propulsion notices via the Go app? Could you clarify how high you were in the screenshot you provided? Would it be possible to sync you flight log so I can have someone take a look at it?

Hi Jamie.

I am not receiving any tuned propulsion notices. I would estimate the height to be 10 to 15 metres. At first I thought height maybe an issue in that the VPS was interfering with information from the other sensors. The flight shown above was high enough to negate this. I have also tried disabling the VPS in the app but this does not help.
I have now synced the flight logs via the go app. Is this what you require? If you need something else please let me know.
Thanks for sticking with this one.

Regards.

Dave.

Thank you for the update, syncing the logs in the app is exactly what I was looking for. Lastly, could you please provide your DJI email and the date on that flight record?

Hi Jamie. The date for the log is 17/08/2016. There are 5 flights that day. The log shown above is the one with Ditance 1135 M, Time 6 Min. The 5 Min and 6 Min flights on the same day may be worth looking at as well. They had manual return to home activations.

Many thanks Jamie. I have now removed my email address from my post. Let me know if you need it again.

Dave.

DJI-Jamie Posted at 2016-8-26 13:17
That would be appreciated.

If you can please let me reply to a email other than one I use on here please. Removed email address.
I can then provide the primary one I use for DJI.

Unfortunately I'm unable to send private messages. Have you possibly been in contact with the North American Support team and provided flight log information to them regarding this issue? You can also take Dave E's approach as well.

I'm out of warranty.  Funny it didn't do this till 1.9 firmware and the x5.

If this was due to a firmware issue and not a crash or normal wear, then there is still a chance that the service can still be covered. A RMA can still be a viable option if you want to have the unit evaluated more in depth or we can still attempt to find the cause remotely. To clarify, was the email you originally provided the one used to register this unit?

I have previously reported the exact same issue.  I even sent my Inspire 1 V1 with X5 upgrade back to my DJI approved dealer as its still under warranty.  They checked it and stated it was fine.  No issues.  Out tonight, open field, drifts left, flies off left and warning message GPS has been lost, and tune propulsion messages constantly coming up on the screen. Constantly getting compass errors, interference etc. Yet fly my P4 in the same place, same weather, same everything and not one single problem.  No drifting, no compass issues, no GPS issues, nothing at all.  Im certain that there is something not right with it.

NO -Email Removed- is The flights where it really happened bad are the following dates.  8-13-2016 15:55:50.  8-13-2016 16:16:47.  8-16-2016 13:19:58. 7-22-2016 09:09:00.  That is a few of the main ones.  Please let me know and will remove email when you see this.
EDIT...  Also Jamie im not breaking any rules in this but I do beta test for you all and been a tester for over a year.  So Tahoe and others know I regualry look for this stuff.  And this isnt right. I just have not had time to really reach out to him.

I thought my mind was playing tricks on me, but I now see that others have discovered the same.  On my short flights at the park, I suspected that the aircraft wasn't flying straight when flying in reverse (I don't really do this often but started to when I saw this occurring).  When I flew forward, it seemed fairly normal, but yet I'm not flying the distances that everyone else has tested.  I can't really see my aircraft once it gets outside 600 feet.  Let me know when you come to a fix and I'll follow suit.

Hi Jamie. Do you have any updates regarding this yet please?

Dave.

On that date, they were able to tell that the unit was fighting against the wind, which could be causing drift. They do not see any apparent drift issue from the compass or the GPS. You can make another attempt to calibrate the compass in a more interference free area if you still feel that it's an issue, but there is no visible issue at this time. Of course, you always have the option to have the Europe Support Center physically take a look at your unit for further diagnosis, as they can pull more data off of the aircraft.

Boogieman Posted at 2016-9-10 10:07
As would I.

After looking at all the dates provided from the Go app, the flights all appear to be normal. There was not as much wind as Dave E had, so that was not a factor. Some minute drifting can happen, and with what we can see it's within a reasonable amount. One of 8/13 logs had an instance of a stronger drift than what would be expected, but it did not seem to replicate itself in the other logs. Given the one instance where the drift was a little more drastic, your unit could benefit from further diagnosis from a repair technician.
