[C320-list] Cutlass bearing and...

[Jeff Church]

FYI

When I spoke to MaxProp and later when I spoke with PYI about a flexi shaft 
coupling, they both told me that in order to avoid problems related to 
vibration, the distance from the propeller hub to the strut should be no 
more than the diameter of the shaft. I'd guess that would be even more 
important with a softer bronze shaft.
