While a mid-air calibration may work (although it shouldn't have to be done) for a gimbal that has a <b>constant </b>tilt, I don't think it would do much for a drifting one.

</blockquote>In response to your earlier question, yes tilted horizons are a well known problem that has plagued DJI quads through several generations. You have probably already seen in a search of this forum alone just how many times it has come up.<br />
<br />
Good insight about the difference between a constant tilt and a drifting tilt. They are very different. Most people immediately reply back to do an IMU cal (totally level and after refrigeration!) or a gimbal cal, or to adjust the gimbal roll in the app (later the C2/camera wheel combo was added), or fix it in post, etc. Again, as you noted this is awesome for a static tilt. Sadly, they don't work well for a <i>drifting</i> tilt. No matter what you try or how many times you try it, none of these will fix a drifting horizon. At best, you'll think its fixed and be happy for a flight or two, but then the tilt returns.<br />
<br />
Also, the tilt you are showing is not as bad as many have posted here. For those others with a worse drifting tilt than yours, I have suggested they send it back if still within warranty. Yours is not nearly as bad however, so it just depends on how much it bothers you. Chances are that it won't just go away no matter how many calibrations you do.<br />
<br />
As always, just my very humble opinion.</div>
