Paul;

Been thinking about the GARGANTUAN Gyroscopic Forces during the Dyno
tests....The increase in 2.5 lbs/Blades magnifies these Forces to what I
consider a very dangerous level for non celled test..Maybe we should be prudent
and consider lowering the Bowing RATE hz commensurate with the percentage
increase in Blade weight......This will definitely meet the original Test
criteria, since we unanimously agree that 7lb Blades are very feasible, we can
always re-run the test at the increased RATE hz with the lighter Blades.
That's one hell of a FAST flywheel to see loose, and no time to run :-(  Not to
mention if a Blade lets go.....Engine, stand and Trailer will be all over the
place......Of course, the LAEV will survive :)

We have to keep in mind that we are designing for practical Strength & Safety.

Not to worry Santa Paula is out in the sticks. Nothing but a couple
of miles of river bottom over a 200 degree arc.
A big problem would be finding the peices :-)
