The three blade Second Generation Hartzell composite is being
test flown on Rob Hickman - Advanced Flight Systems RV-10 aircraft. He
also has the same blades on his two blade RV-4. Cirrus and Mooney have it
now in GA production. VANS said the price might be in the $14,000 range.
So, if Joe is willing to offer the option ask the factory.

Subject: [LML] Constant Speed Prop for IO-360
I am at the interesting but
expensive stage of buying a prop for the IO-360 engine in my 360. I would
be interested in hearing views as to the optimum prop. I have seen and
flown in 360s with the standard Hartzell 2 blade 68" metal prop, and know
of the MT 3 blade composite. I have heard rumors that Hartzell is also
developing a 3 blade composite unit. Much as I might admire the
Aerocomposites prop, it is outside my budget, and I know that the Whirlwind 151
props have a poor in-service history.
I would like to get some inputs as to which props people are using and what
their opinions are. I would be particularly keen to hear from anyone with
comparative experience, ideally with data. Apart from the usual
requirements of cruise efficiency, especially at higher altitudes, I also will
eventually be operating off a relatively short strip, so take off performance
is a significant factor.
I would appreciate any and all inputs. Thanks.
