Hi, I have just purchased the new DJI mini 2, upgrading from the mini 1. My first flight with this drone has really impressed me! The Occusync 2.0 is just so amazing compared to the "enhanced wifi". However on my second flight, I took off, and the drone just went all over the place! I had no clue what was going on. So, I manually took control of the drone to land it. Keep in mind, this is a brand new drone and I have not crashed it. Before, this flight, I have calibrated the compass and waited a couple of minutes before I had enough satellites (17).  Here is the flight log: https://app.airdata.com/flight/78a6e314b931b4c15d2da410fd65e288/GENERALOverview


Please let me know if you know what is going on.

Thanks a lot!

How many satellites did you have before taking off? did it record the home point? I'm sure someone will chime in to read the log.

These loss of control issues are mounting up on this drone, I haven't had that problem fortunately but I have had connection issues losing signal to the RC and little distance.

Hopefully someone can help with your logs.

You had a weak GPS signal and then a hompoint updated whilst in flight.

Don't think I've seen that in my logs.

You're hp should be set before take off. And if you had 17 satellites, getting a weak GPS signal is scary.

Took it out today and I haven't had this issue so far, wondering if it was the compass "interference"?

Hiya,

Had a look at your flight, indeed a messy hover stability!  (yellow parts in the polar chart = no RC pitch and/or Roll input)

Not sure  but the compass and yaw values are too far apart, so my guess is mayby a kind of compass/yaw error.

Do not move your drone while and after switching ON (button on the mini 'stupid' position)
If you do it different than mu advice, get used to hold mini normal horizontal with finger under the drone to select ON.

But a message in the log at start "GPS signal weak GPS signal weak. Positioning accuracy affected. Fly with caution" at start, despite of good number sats and reception."


cheers

Is it UAV data?
