• 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.

Sheet metal work is killing me. Any suggestions about how to go about easily forming the curved piece in the middle?

I'm sort of getting there by wrapping it around a 2" pipe and a small piece of aluminum. But bending a larger piece (the ailerons are 60" long) is not going to work this way. If you look at the attached rib drawing you will see that there is more of a bend than Marquart drew in Section D-D. And 2024-T3 is stiff and has tons of spring back.
