Paul & Ed, As one who experienced a prop failure on first flight, please

would really hate for you to look back the next day and think, was it

really necessary to do in

flight testing on the new design, complex, high risk piece of equipment

on the very first day it

was ever spun up?

Herbs comments are well worth considering. When the prop was nearing
completion I was quite impressed with Paul's initial comments on the
thorough test stand running it was going to undergo and felt this was a
professional approach that would minimize harm and associated bad press. Why
the rush to in flight testing? Me thinks it is partly out of a strong desire
to show it off to the community at SnF; very human but maybe not a good
idea.
