   Hi,
   I bought a propeller through american propeller some years back.
It's a 70" hartzell constant
   speed prop I'm planning to use on a Lycoming I0-360 B1B.
   The prop hub is model # HC-C2YK-1BF, and the blades are model #
F75666A-6. I found out
   recently that there are harmonic problems with that blade length. Is
that true? Can I have the
   bladed cut down to 68" (which I understand is a "good" length)?
   I'm no propeller expert, so any info here would be appreciated!
