Foreword: I have already installed 2 times for safety last FW 900, calibrated IMU and compass, changed all 4 propellers. (Before running today's tests)

The drone moves in oblique, only using the stick forward.

Changed remote control problem persists.
also changed the right stick up / down position, instead of forward / backward..the problem persists,
days with or without wind always the same result,it is so from July.


For greater clarity and understanding by everyone, I show you the video while it is in RTH
so it excludes HUMAN error while using the remote control.

Wind? Does it track in a straight line ever? I have also noticed this on RTH but have no issue with that.

you say, which is normal in rth flies oblique?

that is, the face of the spark DOES NOT point towards the home.
because what happens to me.

always always always!

if I go straight under 5mt the drone works ok.

if I climb even just 2 meters, always turn left.

Given that you have covered everything in terms of refreshing and calibrating I would contact DJI Support for a professional diagnostic and possible replacement.

oh Tnx Wachtberger

Lian, please export the flight data and the black box data for further analysis. Thanks for your support.

ok guys,it very strange..
today I reset factory mode, then I went out and asked me to calibrate IMU or not started ... calibrated and the drone after 7 months went straight! : )
even in RTH.

I say strange, because all the updates never reset the drone ... (I thought so)

so just press on DJI assistant reset ... absurd! now I can sell it quiet.

Glad that fixed it for you!

Mine has been flying the same way as yours. I just restored factory settings and refreshed the Spark firmware, calibrated the compass and IMU again and now she flies straight again. Thanks Lian82 !!!
