My replacement Z15 5D (the previous one had a weird twitch) is roll drifting really badly. I tested it quickly in a hover and it seemed fine, but I got a chance to fly a lot over Labor Day weekend and noticed that it is rolling a ton as compared to the previous one I had.
The previous Z15 5D didn't roll (very minor roll) but it twitched down and left randomly. This new one, the replacement US Hobby sent me, doesn't twitch at all but it rolls so bad that I'm not comfortable using it on jobs.
I really don't want to go through the trouble of sending yet another one back. Do any of you have any ideas as to how I might be able to fix it?? All firmware is fully updated and it is mounted to a well balanced octo.
Here's a video showing the roll problem:
And here's the video from the previous Z15 5D that twitched:
