I assume this is ArduCopter 4.4.1 ?

You have 4.4.0-beta4 firmware, best to update to latest stable release.

Vibrations are the primary problem

Vibrations over 15 to 20 should be addressed, and vibrations up around 30 are a problem.
See in this graph the clipping events number around 10000 - that is a lot.

The vibrations cause the copter to think it is falling, so it increases motor output and you see it climbing, it still thinks it is falling…

Definitely set these:

BATT_FS_CRT_ACT
BATT_FS_LOW_ACT

and ensure you battery voltage low and critical values are correct.
