• 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.

I noticed that there are errors on the plans, but as long asyou can rely on some dimensions, it is not a bid deal.
The problem is on the wing ribs, where there are no dimensions (except the spars and distance between the front and rearspars).My wing ribs plan is too short verticaly (the spar could not fit for about 1/16") and too long (20 1/8" instead of 20" between the spars). Moreover, there are some small diferences between the standard rib plan (page 21) and the plated rib plan (page 22).
My plans were printed 3/01. Could they have stretched ?
Did someone notice this ? What is the measurement allowance ?
Are there some other dimensions available for the ribs?

Thank you.
