If you sign up for Mavic Pilots and then take a look at this page, it might fix your issue: http://mavicpilots.com/threads/g ... l.9958/#post-158560 - there is a small bracket at the back of the gimbal and it needs to be underneath it - its easy for it to dislodge and be in front.. so check it out.
Please upload some original videos to dropbox or google drive then send me the link.
I'll help to check it.
Besides, please follow the video tutorial to check the gimbal again.
