• 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).

Original plans

Hi guys!

Still trying to get a handle on building a Pitts or a Toot! I have a question on plans. I see at Steen Aero they have cad prints and original prints available. Do most people go for the cad drawings or the original ones? I was reading that the revised Pitts had a stretch incorporated into it, is that the reason for the cad plans or does the original have the stretch updates?

IfI had to guess, the original plans must be tougher to read, is that it?
