• 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).

Hey, I have been playing around with setting up the empennage of late, ans came across this thing in the box of trash/hidden treasure that came with the salvaged Skybolt I have.
I was working on making sense of the trim tabs and connections todaywhen I noticed this tube with horns on it, I assumed it was part of the trim mechanism, but no where can I find where this thing would go. The blocks on the end seem to be made of some sort of phenolic or tufnall, the ends of the tube have some sort of rough cloth around them (for friction?). The two horns are not of equal length, and they are off-center. Any ideas?
