    Wood Prop info/advice for 160 hp O-320 B2B

    Would anyone with knowledge or experience in wood prop options for a O-320 B2B care to comment on the best wood prop setup for a flatlander on seasonal wheelskis and floats. Get up and go is somewhat important but not as critical as with supercub strips and high density altitude. I've run a Borer with a 43 pitch which worked great, but most of the time I wished I had better cruise performance at the cost of slightly less takeoff performance.

    It's for a PA-12. Certification is a plus but not required.

    I have a narrow deck 0-320, 160hp in my 2+2 and really like my Sen. 80X44 wood prop.

    Hi,
    Jim Drometer is the wood prop guru, especially on the Pa-12. His contact info used to be drometer@aol.com or 800-325-5474. He sells the props and also has extensively tested all of them.

    How much did it cost and what does it weigh? Do you have any metal prop comparisons regarding performance?

    For a given RPM the 80x44 Sens. would probably cruise about 8mph faster and would indeed cost you some takeoff and climb performance. It weighs 18 lbs.

    Perry, on my plane, the 80x44 decreased my ground roll on take off about 75ft compared to my wood 74x56 and decreased my cruise speed about 8mph

    There are a couple of guys on this site that discussed using wood props albiet on Super Cubs.
    I think one of them was JMBreitinger and possibly Sam Beckett discussed using a wood prop when he had his SC.
