Just tried to fly my Spark and it gave me a warning to remove the gimbal guard. Which I do not have. Checked the gimbal and under initial investigation, found everything fine. Swapped batteries and the warning went away. However, I noticed that the camera was facing down slightly when powered up. Rotated the gimbal via the remote and didn't have any issues moving it. Took her up into the air and the video feed was super jittery and I got a gimbal motor overload warning. Brought her back down and palm landed her and noticed that the gimbal was hanging funny. Looked closer and found that one screw was completely gone and the other had backed halfway out... What the hell? It's definitely not a user serviceable item. You'd have to disassemble the entire craft to get to the screws. Guess I'll be calling DJI tomorrow...
