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.
