• 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 took my old flop tube out which I purchased from Aviat about 10 years ago and this is what it looked like:


As you can see, there are three rather fat "O"-rings on it, they appear to have held up ok, no pieces missing. As near as I can tell from the picture in the catalog, the ACS flop tube has one "O"-Ring on the end and is $70 as compared to the Avait one for $270. I know it a previous discussion, the use of "O"-Rings was discussed with rather negative overtones, but these don't seem to be coming apart. Any thoughts?
