• 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 am considering building my own 4 into 1. Looking for some input for the best source for SS tubing, flanges, ext. I don't see a lot on ACS. I know that some of you have built your own so if you could share your experience here I think it will be an interesting thread.

I just can't commit to shelling out $1,500. for a system from one of the suppliers. And I just like welding and fabricating.

Neil, I saw this thread while searching around that you had built a system. If you could chime in here that would be helpful. Thanks.

"I used the CAFE report when I made my 4 into 1 also. Full power run and lean to peak. You can see right where the tail pipe needs to be cut for optimum length."
