• 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).

Finally replacing the crankcase breather tubing in my IO 540 powered Skybolt has a 1 inch aluminum tubing part way then has some sort of clear tubing to under pilots seat and then reduced to 3/4 inch clear tubing to tail. I have been researching required breather tubing size can’t find much. Looking for input on what size tubing everyone is using. I will run aluminum tubing from firewall to tail
