Hi,
I have my Mavic since April, all good so far. I also have flown a P4 and have built a couple of NAZA M2s.
I always keep everything updated, and have the latest iOS 4.12 GO4 App, and firmware .800. Everything working as advertised so far. No crashes, no strange behaviour, all perfect.
This flight however was a little "glitchy". Soon after takeoff, after moving just up vertically I heard the motors spin louder for a very short time, like a gust of wind, but shorter and more intense.
I tried to move slightly the aircraft in all directions, and commands were responsive, but the start recording button would not respond. (Yes I had a card, and had just reviewed photo/video settings and formated the card in GO4).
At one point, the aircraft made a yaw jerk (maybe 20 degrees) and I decided to land to avoid any trouble. Landed without incident, turned everything off, restarted and the next flight everything was well.
All of this got me curious, so I've downloaded the DAT using Assistant2 and tried to analyze it using CSVView (https://datfile.net/Doc/intro.html). Could not find anything conclusive, but while looking at individual compass mods, rather then the agregated one, the variations looks odd to me. Also "direction of travel" seems to jump up and down very sharply.
Other than the small yaw jerk and video record button not working, everything was ok. I've checked IMU and Compass status prior to take-off and was the same as always, low values and on the green. The location is where I make a lot of flights since is near my house with no issues before.
The Dropbox link for the file (41 Mb) is:

If someone has the time to review the file it would be greatly appreciated.
Thanks.
