• 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.

Rudder Trim: Bendable Alum or wood wedge

I’m at the point of Indecision. My CB-1 came to me with no rudder trim. Using various wedges, I found the perfect trim but I hesitate to glue or tape the wood wedge onto the fabric. The option, is to use the tried and true bendable aluminum tab and drill the rudder for rivets.
When comparing the two, I think that wood may be a better choice because once it’s adhered to the fabric, it can’t be bumped and inadvertently changed and is a cleaner installation. But how to attach a sealed and painted wood wedge without doing damage or losing it in flight. OTOH the Aluminum is changeable and replaceable and probably won’t come off and land on my neighbor’s roof.
Any comments are greatly appreciated!
