• 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.

Because I have never been a proponet of off-setting the vertical fin to compensate for engine torque in an aerobatic biplane I have never done it. Because I have never done it I don't know how to do it. If I don't mention it in the manual sooner or later someone will want to know how/why. I can't imagine why as the rudder trim tab accomplishes the same thing and is much easier and better looking but, I am going to put a blurb in the manual on how-to, so:
A) Is the rear turtledeck former reshaped off center to the fuselage centerline and the vertical fin attached (which would cause a turtledeck problem in my eye) or:
B) Is the former built to plans and the fin attached off center or:
C) None of the above ??
D) And by how much is this offset, 1/2" - 1" ??
