• 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.

Both items left over from my build:

$625 - SDS lightweight flywheel, 3/4” lug, 149 tooth flywheel with alternator pulley and clear anodized finish (does not have magnets for electronic ignition) Aircraft

$295 - Aero Classics 7 row oil cooler

Photos available if you need them but they are booth new in box. I will take them to Oshkosh and sell in the Aeromart but thought I'd offer them up here first.
