• 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.

I ve been tightening my drag/anti-drag wires today and know that steen says to tighten them 25-35 inch lbs @1/2 deflection. But how do i know the wing isnt twisting??? Ive got a digital level(.1 accuracy) and the wing incidence jigs from steen. Ive got all the ribs within .3 deg of each other, but is this close enough? Im going to run a string length wise down the wing at both spars and see also if anything is twisted too. Mostly wondering if im on the right track or if im in left field. Any thoughts? Also, this was flying plane, just replaced lower rear spar in this and mostly just checking EVERYTHING out too.
