• 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 could see this thread beginning to form so I started new.

Those planning an inverted system need to include a breather pipe of about 3/4" dia. running down one side of the fuselage, usually on the right, to the tail with an exit somewhere near the tail spring. It should pass through the firewall with a flange fitting. It should be very slightly down hill toward the tail. Not much, because it has to vent when inverted as well. Just a degree or two is enough. This will keep the airplane much cleaner.
