3 Blade Hartzell CS Composite

[Christopher Murphy]

Thats more than I paid for my engine brand new... too much considering the value of a typical Rv4 o320. Why couldn?t they just make it a two blade and maybe keep the price down a bit?

They sell a 2 blade composite CS prop. That's $15k w/spinner from Vans.

Of note, this 3 blade Hartzell requires a dampened crank. I understand these are engines with the "6" in the engine suffix.

Questions for the engine pundits.

1) Does this 3 blade prop require a dampened crank for vibration frequency issues?

2) Can a dampened crank engine be used with a standard 2 blade prop such as Hartzell G2YR/N7605W-2X? In other words, would an engine with a dampened crank provide more flexibility in prop selection?
