Hi Everyone,

I'm a recent proud owner of a DJI Mavic Pro (got it 2 weeks ago), while taking it out for a spin I noticed it drifts to the left when I have the right stick straight up (going forward), the wind conditions were good and it was actually drifting against the wind, so obviously something wrong with it. Please watch the video for further explanation:


Is there a quick fix for this? Please help!

TIA,
Rodrigo

Hey Rodrigo, does the issue appear in every flight? If yes, please try to refresh the firmware and do gimbal calibration to see whether it helps.

Refresh the FW using Assistant 2, calibrate the IMU on a flat surface and change the props. That should do it. Note that you will get minor drift in faster wind speeds, especially in open areas at higher altitudes but it shouldn't be this bad.

Thanks guys!
DJI Susan, yes.. every flight

The firmware is up to date, but how do I refresh FW using assistant 2? Is there a tutorial online? Also, should the compass be calibrated every time before I fly? I was doing that to my phantom 3 and it never did any drifting.

I'll try your suggestions and let you know.

Thanks again!

ok, so I calibrated IMU and compass and tried it again, still drifting like the footage. I then tried CW's suggestion on refreshing FW thru Assistant 2, recalibrated IMU, controller and compass and now it is much better than the footage however I can still tell it drifts like that in certain occasions which are not related to wind (drifting against the wind actually). I'll upload some footage to demonstrate soon. This only happens when the drone flies forward, when it flies backwards it never drifts. My DJI Phantom 3 standard never did that, so I'm suspecting there's something wrong with this unit.

I had the same issue couple of times before but sometimes it happens and others all works great, even the huge drigt when U stop the drone, but I think this is depending on where u're flying , if the ground patterns  aren't contrasty for the censors or if u're in ATTI instead of GPS of even if the SATs Locked aren't enough.
Before  U fly let the drone hover a bit  and Make sure u're In GPS mode, Sats are 12 and above and away from all interference areas and try again.
EDIT: When u Calibrate the IMU and compass make sure u don't do it on concret , I think grass is a good place for this away from metal objects

Thanks for your reply, my neighbor's mavic pro is perfect, it never does that, we did a side by side comparison and mine drifts while his goes on a straight line, definitely something wrong with my unit. I also calibrated compass and IMU on grass like you've suggested but it doesn't seem to have helped much, still drifts. Thanks again!

So I decided to make another video on the drifting. This is after upgrading the FW thru Assistant 2, calibrating IMU, compass, gimbal and controller, you can tell it still drifts to the right quite badly, the wind condition was great today and I'm flying on GPS mode. This is pretty frustrating, I strongly believe I've got a unit with defect, my neighbor also has a DJI Mavic Pro and we did a side by side comparison and his unit flies straight flawlessly. I'll need to contact DJI for a replacement.

Follows the video:

Before you return the aircraft do a stick calibration on the rc after a cold imu to the a.c. and see if the problem persists.

Thanks for the reply, as I mentioned before I tried that and the problem still persists.

I have not, the unit was defective, returned and got a replacement. The new unit never drifts, flies flawlessly so far under the same conditions.

I had the same problem, now I'm waiting for the new drone from DJI support ;)
