• 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.



Are uncovered I-struts a problem?

I opted not to cover my I-struts (ok I admit I didn’t know I needed to), and the airplane is now in final assembly. I hate the thought of taking them off and the month or more delay it will pose to cover and paint them.
I am ok with them visually being uncovered but am wondering if the drag will be severe. Years ago I watched an old NACA film about the drag difference between a round rod and a faired rod of the same frontal area. The difference is huge. But since the skybolt is such a draggy airplane anyway is this really a concern I should worry about?
Should I fly it and see what happens, or will I regret it? I may not know much even then, because each airplane flies differently enough. Anyone ever seen a skybolt fly naked like this.?
