Walter D, thanks for your input.

I wish I could remember where I saw this on the web, but it goes somewhat like the following:

1 - **% of all crashes occur because of poor setup on the plane.

2 - **% of all crashes occur because of poor maintenance of the plane.

3 - *% of all crashes occur because of "dumb thumbs".

4 - .00*% of all crashes occur because of frequency "hits".

I have one plane to crash because of "suspected reasons" but, because this plane had come out of a radical rebuild I suspect reason no. 1 was the culprit.
