• 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.

Ok. Me again. so Im building the pitts s1/ultimate. my question is since the Ultimate wing has a flat trailing edge, is an aileron cove necessary? When I place the ailerons on the hinges there is a definite gap between the leading edge of the aileron and the trailing edge of the wing. Racing at Reno yes I understand the importance but for competition akro im curious. Building a "cove" would take some work but there hasnt been a single square inch on this plane that hasnt. What do you guys think.
