• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Anybody using athree-blade Catto ontheir 180hp S-1S? With my current Sensenich 76x59, full power straight and levelsees 160mph IAS @ 2900 rpm. Stabilized full power flight at 3000 rpm sees 170 mph. Climb at 100mph sees 2500 rpm.Craigmakes a 56 and 58 pitch prop (72 dia)for the S-1S and I'mtrying to figure out which would work best, without losing high-end speed or low-end thrust compared to what I'm running now. Just looking forsome comparison data for anyone running his prop on their 180 hp unmodded S-1S.Already looked over search results. Thanks
