I went flying this morning on what seemed to be a perfect day; 15 min. into sunrise no wind; perfect conditions for my flight mission. After I got out to about a little over 800ft dropped WiFi signal (typical) so I landed Air4c 1 (my drones name) rebooted the Q & St10 and flew the rest of the mission (only closer). After playing back the video I noticed the first 5 min. of footage was very unstable as if there were high winds then all of a sudden the video stabilized. And then it dawned on me; I forgot to take off the gimbal/camera cover. I wish they would make them a different color (red) as a visual reminder to remove, because the black one blends in well with Q & the camera. Luckily after watching the video I was able to tell where about it fell off. I went back to that location and found it. No harm, no foul; hope I don't forget to remove the cover again. I think I'll paint red myself.
