Ok I have a c-85 with o-200 pistons and upgraded cam and some other modifications. The builder thought it should make between 110-120 hp (might be optimistic.) The problem I am having is that I feel like the prop might be limiting me. I am hitting static rpm of 2700 on the ground and initial roll and takeoff is like a rocket. Then I hit about 80mph and its like a brick wall. In flight max rpm is about 2500-2600 at a cruise of 90-95mph. The prop is at least a 70 in prop I need to double check the pitch today but I am assuming its fairly low pitch to get the static up to 2700. My question is would it benefit to move to a smaller but higher pitch prop? what are you guys running on your smiths? Anyone use an aeromatic?

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.
What prop?
