• 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.

Hi all,

Im returning an old Pitts S-1E to flying condition. It has an IO-360 200hp and a C/S prop. I decided to have the prop overhauled just because it’s old and has no logs. The shop took it apart and found evidence of a prop strike and says the prop is beyond repair. (The prop strike was not in the Pitts).

For “only” $17,400 and a 16 week wait they can get me a new one. Or….I think I could put a new Sensenich ground adjustable prop on it for a fraction of the cost.

so the question is: is a c/s prop worth it on an S-1? Of course it’s heavy and I’m concerned about the CG for when I reweigh The airplane for its new W&B.

Is there a massive performance difference? Is it worth almost 20G’s? I’m 99.3% sure I want to go with the newer lighter weight Sensenich prop but thought I’d seek some advice from the experience here.

BTW, I’ve started a video series on the “restoration” of this E model if your interested.

Thanks, Mark
