I agree. I thought I had corrected this "tilted horizon" problem via multiple IMU calibrations - including the refrigerator chilling prior to IMU calibration (boy did my wife give me funny looks when I did that) an multple Gimbal auto calibrations befofore and immediately after IMU calibration on a firm absolutely level surface. BUT THE TILTED HORIZON ISSUE WILL NOT PERMANENTLY GO AWAY! Sometimes its gone for one flight, but comes back the next flight or during the same flight. And yes - iRemoved the foam piece behind the gimbal immediately after unboxing. I have also tried adjusting the gimbal roll to get the camera level BEFORE performing an IMU calibration, but that didn't fix the tilted horizon permanently either. And the horizon is ALWAYS higher on the right-hand side of recorded videos. Since this is prevalent in most of the first flight videoes and many 2nd, 3rd, . . . videoes posted on YouTube by Phantom 3 owner's, it is obvious this is a pervasive problem affecting many, if not all, Phantom 3s out of the box. It appears some P3 owners either got a level camera out of the box, or the IMU/gimbal calibration permanently fixed their tilted horizon problem.
I certainly hope that DJI is able to release a firmware fix SOON that addresses the tilted horizon issue. However, I'm beginning to suspect this is a due to a bad factory calibration on out-of-calibration factory equipment. If so, the only permanent fix may require returning the P3 to DJI, or exchanging it for another if your vendor allows this.
If anyone has a permanent, reliable fix for the tilted horizon issue that survives multiple power on-off cycles and camera tilts and aircraft yaws, then please post it for the rest of us. THANKS. |
