• 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.

As I'm about to build my #9rib (last ribbefore the tip bow) for both upper and lower wings,I just discovered the airfoil coordinates were missingon both the S1S plans and the S1SS plans (in the last case I have a theoretically 1:1 scale drawing, but it appears in fact to be wrong as some theoretical lenght does not correpond to the drawing). Would someone have those coordinates available ?

Thanks for your help...
