• 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.

So, since I have an airplane without an engine... I figured it was a good time to do some MX that might as well be done now.

So I am replacing my flop tube. I pulled it out and it is 15.5"..... So should I order a 15 or 16? Or where can I find a 15.5?

As an aside... This was a PITA to remove, It was too big to come out the front, so I had to fish it out the top. I made a mistake and tied to the big end and that took some work to jiggle it out.
