Steve,

 

Actually I was joking. I was amazed how little vibration the airframe had so I shot a video of the water bottle. I will have a look at VibSensor. It will be interesting to see the results.

There is a free app called VibSensor that runs on both android and I-phone/pad platforms.  Although not a research quality system, running the app and holding the device firmly against a surface of interest will give objective results.  This may give a basis for useful comparisons for the terminally curious.

In my case, dynamically balancing the MT prop and the flex plate-damper combination as separate units made a noticeable difference in the system vibration signature.
