• 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.

This is one of Lycomings engines for the homebuilt market. I recently took a job at Southern Air (Turbine Legend Aircraft) and one of the customer projects has one of these with it.

If I could afford a new engine and I was on the fence between a 4cyl or a 6 cyl for my project, this would go along way toward knocking me off the fence.
