Gimbal calibration issues - roll left down

[Neill Watson]

Further to my last post, my gimbal still gives issues. Starts up and achieves horizon just fine. As soon as you begin manoeuvring, it steadily rolls left horizon down by around 20 degrees. Stop to a hover, it gradually rolls level. Start flying again, it loses the level horizon.
I've had this drone for over a year, has never given any problems, Now, after being stored for a few weeks, it's struggling to get back to normal.
Secondary issue that developed today was the gimbal refusing to enter 'follow' mode - that is the pan switch fully forward. Would only to that after I landed and reset.
Have calibrated everything in the same way I always do, away from buildings, the car etc etc.
Can post an example video if it helps.
Any thoughts are welcome.

An additional element I'm seeing as I view the footage is that the first clip has the horizon dead level, the second clip starts a little off and gets worse, third clip a little worse etc etc. It's as if the error compounds itself.
