• 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 received my wing tank from Steen today. The welding is extremely tidy.

I will be soon learning to weld 4130, but wouldn't fancy tackling aluminum.

Tip from a local A&P: use some acetone with a drop of food coloring to test tanks for leaks. The coloring acts as a dye, and the extremely low viscosity of acetone means it will findthe smallestleak waybetter than gas.
