Paul,

I'm not an engineer but you and others on the newsletter list might find an article in this month's Sport Aviation worth reading. It deals with a newer approach to detecting defects through vibration analysis. It could be useful for the TTC project since so much of what you are using are 'one-off' pieces.

The EAA article can be found here:

The company it covers is a Latvian startup called Advanced Vector Analysis (AVA) and their approach is apparently so effective it reduces the number of sensors required significantly. They measure the normal x-, y- and z- axes but add a fourth dimension, i.ie. tracking vibration over time. I'm assuming you can track down the academic research publications documenting the processes and results. The AVA website can be found here: http://www.ava-labs.com/en/
