Hartzell Prop

[Fritz1]

Any pireps on the Bravo Hartzell prop? my understanding is a couple were installed, the TKS prop is not certified yet, takeoff acceleration and climb are considerably improved, maybe by 10%, high altitude cruise is the same or maybe 1-2 kt better, probably hard to tell without flight test instrumentation, so, who has one and how do you like it?

It's the same prop that Cirrus uses on the normally aspirated SR22. Great prop. Very smooth. The scimitar blades make more thrust with less drag, so acceleration is improved over the previous props. It's also a bit quieter due to the tip shape. From experience with both props on several Cirrus, I would expect the Bravo to get the same benefits. Now if Hartzell would just put the composite blades on the Mooney prop...they've done it on the Cirrus props since 2008.
