• 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 hear alot of talk about flexibility with the different covering systems. Is flexibility really a good thing? Remember the fabric is a part of the aircraft structure on most fabric covered airplanes. The fabricprovides mostof the torsional rigidity of your wings. The more flexible the system the more your wing will twist. If you don't believeme grab the wing tip of Cub, Champ and gently twist it.Try this with airplanes covered with the different systems and you will see what I mean. Flutter is real and with the high speeds of some aerobatic ships we need all the rigidity we can get. I myself will stick with the tried and true rigidity of Butyrate.
