• 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).

Rerigged my wings, tightened some brackets that had worked loose, changed my 4-spade setup to just the two on the bottom wings. Spade shape went from square with upturned edges to flat triangular. Pictures on my web page.

Moving back to the tail, I notice that in level cruise flight the elevator is deflected down, with the trim tab taking a pretty good bite. Pitts says to set it at +2 degrees (from fuselage upper longeron level), using washers on the front tube attach point.

Any reason to change from the 2 degree to try get the elevator to fly in trail in level flight? Is the 2 degree a compromise between upright and inverted stabilizer rigging?
