Prop Phasing
Hobbsy,Darzeelon,
I am no expert on engines but I would tend to believe Dave Gierke over you 2.
Read page 82 in MAN JULY 2002 under the heading "Smooth A Vibrating Engine With An Unbalanced Prop"
So do you guys figure you no more than Dave Gierke?
I am pretty sure I read the same thing from Clarence Lee somewhere but I haven't found it yet to show you?
