Hi guys, I really need some help with this. Ive had the drone for over a year and have a lot of flight time under my belt. However for the first time I'm experiencing massive drifting issues when flying. The footage is literally all over the place now and when flying forward it's noticeably drifting to the right.. its also the same when moving left to right, the drone is drifting backwards. I'm also losing altitude as well. As you can appreciate this is extremely frustrating especially for the fact I'm now filming stuff for clients. I have done numerous IMU calibrations, compass and gimbal but this is not Fixing the issue. This all began when I updated the **** firmware to the latest update. Can some please advise on how to sort this...? I would really appreciate it.
