Craig,
Consider a fixed pitch.
Constant speed blades are a compromise at any setting in order
to try to do everything well.
I switched from a Hartzell to a Cato fixed composite
blade.
There are many advantages.
They are much less expensive.
They save 50 lbs.
They run smoother.
At any speed over 140 kts they outperform the
Hartzell.
In the event of a propstrike, much less damage is
done.
The disadvantage is a loss of low speed
performance.
I get uncomfortable going into runways shorter than 2500 ft or
so now.
1800 is the limit and you have to watch takeoff performance
closely.

Subject: [LML] Hartzell vs other props for 320/360
Does anyone have any comparison data for Hartzell vs the other props?
I am looking for the fastest prop in cruise and am currently using the
F8468D-14 on my Lancair 320. I am wondering if anyone has flown that and
then gone to an Aero Composites or Whirlwind.
Thank you,
Craig Schulze
