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.
