• 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.

Randy, I noticed some pictures in the users gallery about a V-8 Skybolt. Is that the 215 Buick Aluminum V-8? I thought you menitioned that you used V-8 Chevys? What's the Buick 215 like?

In your previous post about auto conversions you mentioned that auto engines seize-up. There are a lot of corvair, subaru conversions out there that snap cranks, is that true of V-8's? I figure a V-8 would be a bit stouter.

I would think if it is, than you can extend longevity (sp?) by reducing the rpm's and reducing torsional vibration. I would think, that one can reduce rpm by bringing the torque curve up into a lower rpm band by changing the camshaft profile. And maybe one can reduce vibration by using contra-rotating props (using a shaft within a shaft).

Any comments?
