• 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.

Hello all, I am new here and restoring/modifying an eagle. I am going to the boosted aileron/s2c style tips. I have had no luck getting ahold of the guys doing aileron kits and have decided that I would prefer to build composite ailerons anyhow as I have the skillset. (structural/fab/testing,etc. but I don't want to play aerodynamicist)

1: aileron thickness Vs what the wing airfoil thickness would be at that spot as shown were the .156 dimension

. what percentage range is typical

2: flat panel aft of the aileron leading edge shape or would an curve be better.

I have a set of s1ss plans, digitized the wing and scaled the ailerons to the eagle's 40" cord. (s1ss is aprox 36") 29% hinge point etc.
