• 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've built up new elevators per Steen S1-C CAD plans but can't figure out how the elevator trim works. I built the 17-1/4" single trim tab. I was planning to just run a long Bowden (push-pull solid wire with 7/32" housing) from cockpit back to exit of guide tube in elevator.

Is that how people do it? I can't make any sense of the 16" and 3" guide tubes in the fuselage (with 1/4" aluminum tube in between). Will the clamping force of the 5/16" tube cross-ways to the 3/8" tube tighten down enough to grab my cable housing?

And what is the "thing" called a guide end where the 3/8" tube exits the bottom of the elevator near the trim tab?
