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! =Tom >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://www.olsusa.com/Users/Mkaye/maillist.html
