• 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.

Got into some of the inspection holes on the upper and lower wings on my S-1C just to get some photos. The all are in good shape. Noted that the carry through to for the spar is reinforced by doublers on either side of the spar and on the cap bend that gos over the spar. No bent or broken parts visible. The spars are douglas fir.
