• 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've never really liked the thermos bottle type gas cap and I've always wished I had something else. So I'm messing with the cap off one of these fast glass airplanes in the shop and realize that it looks like it would fit my tank. And it does.

The USHER cap is used in several of the composite aircraft and it uses a common "O" ring for a seal making it cost less than a dollar to fix if it gets to a point where it needs repair. This is just a drop in replacement for any 2" ID filler neck.

Best part is that they are in the Aircraft Spruce catalog.
