I'm planning on using a Hartzell blended airfoil C2YR-1BFP/F7497, 74 inch diameter propeller with my AeroSport IO-375. Does anyone have any experience with this combination? Thanks!
I've been told that a metal constant speed props are not recommend for this engine. Something about the 375 engine doesn't have moveable counterweights and is susceptible to vibrational stresses. I haven't found any documentation stating this, just second hand information that I'm questioning...
