Help to interpret log VIBE & PID pitch tuning


We did a XUV Talon flight with the new 3.5 firmware. I need some help to interpret the VIBE graph and the PID pitch tuning graph.

First the VIBE graph : I see Z-accel seems quite high (and in the classical vibration graph, it goes from +5 to -5 which I would consider too large vibrations on a copter). How should I interpret this graph : do I have an issue with the Z-accel or not ? What should be the ideal VIBE values ? Zero ?


Then the PID Pitch tuning graph : I see that the I term is always positive. Does this mean that the plane COG was too forward or too backward ?

      Thx and what about the I term in the PID pitch graph ?
