I did some performance flights with my new C/S Hartzell prop over the weekend. The engine is a O-320, 160hp.
I compiled the data into a neat chart
and some pics of the prop and plane
I flew over a buddy's house and he got a crappy cell phone video clip, however there is a whistling sound/noise, and I am curious if someone knows what that can be?
I know the 9 and 9A whistles, and I think it is due to the flap design... but I haven't heard anything about the 7A...
