• 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.

Gentlemen: I’ve done the Eagle thing, built a Hatz, am have now moved back to my earliest days of aviation....I’m building an experimental J-3. The plans call for six 5/8” metal compression tubes scattered throughout each wing. One is at the butt rib which I would keep and one sits just below the wing and attaches between the lift strut straps which I would retain. I’m wondering if I could replace the four remaining compression tubes with compression ribs? Wonder if I’d take a weight hit? The faced 5/8 x 1/4 compression ribs in the Eagle handle 200+mph. Wouldn’t it handle a hundred in a Cub?

Thanks for any input,
Sarpy Sam
