Hey Goat150,
Go to the search engine on this site and type in PROP. There are a number of prop discussions and one posted on 01-01-05 by Herb Harney regarding three bladed props.
Also, I noticed that you are in Ohio. Several of us in Michigan generally meet up for formation flying. Check out topic "Michigan flyin." Maybe you will like to join us?
Cheers
