• 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).

I have asked a quote for a Catto 3 blades, 185 hp, 2500 rpm cruise, 2800 wot.
Nicole proposed a 74x56 to 60.
According to the experiences I read here it sounds too much. Most builders, with equivalent engines, have 72x50 to 54.
Since I shared this experience with her last week, I have no news.
Doesn’t sound very serious !

Maybe Sensenich with their 2 blades ground adjustable pitch are more professional.

Any opinions are welcome.
Thank you.
