thats FPV for sure!

You need switch gimbal to Follow mode in dji go app settings

Hello, which mode was the drone in at that time? Did the gimbal tilt when the drone flew in high speed?It would be better to post a video of this issue here. Thank you.

Hi DJI-Paladin,
It was in P mode at all times, and have not yet ventured into S or A.

Does this issue happen in every flight?

I will be doing a couple more flights to give more testing to this,, just waiting on favourable we ...

OK. Feel free to post the result here with videos.

Chances are you pressed the C2 button underneath the controller by mistake during flight. This changed the mode to FPV instead of Follow ( there is NO warning of this change ) Its the default configuration on the P4 and P3.. The fact you say its OK after turning the P4 off then on again points to this being the issue..

Sploodge, you might have hit it on the head with this. Yep that C2 button does change between Foll ...

I am sure this will be the reason ( lets hope ).. Best change the button to do something else. I have mine showing battery info.

Sploodge, You were right, It WAS that dam c2 button, Cheers Mate. That must have happened on the c ...

Cool

The horizon thing is a pain.. Although its not 100% needed, what I find that helps is letting the P4 sit on the ground powered on for a minute before take-off. My horizon is normally OK doing this. Also a GOOD IMU calibration goes miles to help it.

I had this on an earlier flight, had me thinking maybe there was a problem, don't think it's happened since. Thanks sploodge, very likely I touched the c2 button and thus this thread explains. Hopefully it'll help others too
