• 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.

Was curious how this departure from the plans would contribute to structural integrity, if at all. Is it more of a redundant safety feature, or an effort to improve strength? I've included some pictures and a video below.

Same plane shown in the link above, the third flying wire is clearly visible in the first few seconds of this video: [ame]http://www.youtube.com/watch?v=LtC31k574uM[/ame]

Another mention of the "third flying wire": http://www.trade-a-plane.com/listing?id=1513105


It may also be worth mentioning that both of these planes are from the same general area, Tennessee/Alabama, so perhaps it's a builders trend. If anyone could offer some insight on this "third flying wire", or the builder Jerry Mills, it would be much appreciated.
