• 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'm going to order plywood soon for my bipes leading edges.

I'm substituting for aluminum leading edges, have a nose stringer and the spars are massive...so its more about cosmetics and durability that lead me to wood, not adding strength(over alum).

Peter Garners replica posts have me interested in using 1mm ply instead of 1.5m(1/16"). It seems like there would be a good weight advantage...i'd be using about 9.5 sq ft. of ply.Also it seems it would be more easily formed.

My only hesitation is if it would have any tendency to sag between nose ribs if too far apart? or will itbe superior to a standard aluminum LE in that respect also?
