• 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).

Hi ALL,
I have noticed a lot of people buying their 4130 tubing from aircraft companies. Is this necessary or can I purchase my material locally. I believe I have a local source for 4130 tubing and flat stock. This would be nice since I could buy smaller quantities and pay as I go. Since this is an experimental aircraft the tubing shouldn't need to be certified. The question is: Is the tubing certified or not and does it really matter?



Thanks, Skyboltchris
