• 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.

Hey guys,

I'm looking at a Pitts S-2E, and the engine is a Lyc IO-360-A1A with 260SMOH. The crankshaft flange has lightening holes in it, I am a little concerned it doesn't have the solid AEIO crank. The engine has a whirlwind 2 blade with a McCaully hub. Are those blades light enough for a "Lightened Flange" engine? This is my first aerobatic airplane, and I don't really plan on becoming an airshow pilot but I want an engine that will hold up. As far as doing snaps go, I would like to be able to do snaps but I don't have a whole lot of desire for Lomshavoks and other hard acro.

Thanks
