Ron as I understand your first post you will be running a 2:1
reduction so
that 5500 engine rpm will correspond to 2750 prop rpm which is
fine. The
prop will start to lose efficiency above 3500rpm. Running 5500
prop rpm is
not for happy props.

through wood props! Both are here to tell their stories, but, I'm

Ron,

I second Peter's comments and unless you have an overpowering
predjudice against natural composites, suggest that you consider
the
following :

Gyroscopic loads

post propstrike consequences

chances of getting the prop exactly right first try

repairability away from home

ability to fabricate replacements

Ron why no wood props? They seem to be the most used.

Run the numbers through David Gall's Excel sheet for props.
I'm
sure it's posted some where - maybe even on his site. If not
I
can
E-mail a copy.

Assuming 165 mph = 84 inch pitch and 76 inch dia.
