There is another thread about this problem but hard to tell from the subject line so here's what I posted.
I'm having the exact same problem.....
Yes I know I left the darn lens cover on for that photo.... I just forgot to remove it for the pic. I do not fly with the lens cover on and have not added anything to the GoPro per the H3 2D Owners Manual that would throw it out of balance.
The mounts are solid and level, I even took everything apart and re-assembled just to be sure there was no operator error. I can say that the problem was not there when I first got the gimbal it has only appeared in the last few weeks. When I push up on one of the rubber dampeners I can get the gimbal to go level but the mount is clearly not level.
I have a Version 1 gimbal which version do you have?
So I wrote DJI about the problem and they wrote back....
"Our technician has determined the case above is a possible warranty issue. I have issued RMA#XXXXX. Please be sure to write the RMA number clearly on the outside of the box you are shipping with permanent marker. If we cannot find or read the RMA number, the package will be refused."
The real bummer is I'm going to have to take the Phantom apart and de-solder the power connections. Really wish I didn't have to do all that.
So tonight I stripped the Phantom down and packed up the Zenmuse and sending it back to DJI with my RMA # attached
Hope they are able to fix the problem or replace the Gimbal.
