• 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.

Looking at the history of our Skybolt, from the day it was built, it has always stalled to the right, or broke right during the stall. Although benign, the stall is still to the right first. And the history supports that from the EAA test flights etc.

In fact, it was so obvious that the builder added a "Rudder Trim" to the airplane.

Later, the previous owner to me added trim tabs (rather significant) as you can see in the photos below to both rudder and aileron.

In flight the stick is in the center, the airplane is perfectly trimmed... but... .

We're not builders, so we apologize if this is a dumb question, but... :

Is there a way to better align the airplane? Or is it something to live with? Any ideas to make the airplane more aerodynamic straight?

The airplane was built with the single upper wing back in the day.

In cruise the airplane flys hands off with these fixes and is lovely to fly.

The previous/previous owner had the dihedral properly adjusted.
