• 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.

Lately, I've gotten the screwy idea that I'd like my S-1S to roll faster, so I've been looking inside the wing to see what it might take. The previous owner (not the builder) said this plane was built from factory kits, but I can't confirm it from the paperwork I have. Aviat apparently doesn't have records on kits from the '80s, though they did rebuild the wings in '99 after a mishap. What I see inside the wings looks like Sparcraft routed ribs used as gussets on one side of normal stick-built ribs, along with wood compression members on either side of some of the ribs (like Sparcraft) and triangular corner blocks at the spars. It's a lot of wood, way more than I remember in my previous Pitts with Sparcraft wings.

And another bit of info: symmetrical ailerons, not Frise.

So, the questions are:
Is this a particular wing design, or just a slightly paranoid builder with a Sparcraft kit who didn't want cracked ribs?

What, if any, additional reinforcement would I need to add for this wing to handle Raven/SS style ailerons?
