RAW IMU Graph?

ArduCopter Copter 3.2

I’d like to get some feedback on the IMU results of a recent flight.
The board is mounted solid with double stick 3M and is flying pretty well…
I only see a couple of isolated spikes, but I admit, at this point, I have an untrained eye.

Thanks, SC

I’d like to see the actual log as the scaling on that seems odd, I’ve not seen the data look like that before.

But it appears like it’s pretty reasonable.

Rob, ET AL,
Thanks, Attached is a fresh log after my 1st successful Auto Tune event. The IMU vibrations appear to me even tighter than the 1st screen shot I posted.
However, the Auto Analyze (JPG. attached also) shows an IMU mismatch IE vibrations or Accel calibration. I had just recalibrated before this most recent flight.

Question: Should the good looking IMU logs take precedence over the Auto Analyze IMU warning or am I missing something?

Many thanks SC

It looks pretty good to me. The scaling I was concerned about (-1000 for Z) appears right in your log (-10 for Z). Gyros looks fine too. I really don’t know what that auto-log warning is about.

Many Thanks Rob,
I’m trying to avoid chasing things that aren’t REALLY broken. LOL
