• 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.

My S1D has just under 60 hrs. and flies as hands off as is possible in a Pitts. On the last couple of flights I've developed a singing wire at about +4G. I can't visibly see any of the wires vibrating and I also haven't seen any slack in them up to about +5 1/2. Anybody have a good method to identify the offending wire, or anything else that might be causing the whine?
My slave struts don't have any string or rod on them, but I've never had a problem with them vibrating. I also have streamlined wires on the tail. The airplane was assembled by a very well respected shop and I'm confident the wires were set up correctly initially. Thanks for any ideas.
