• 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.

I am in the process of covering my Acro Sport, and I have spend one whole day trying to do the hidden modified seine knot, using the pictures in the Poly Fiber Manual. I am sorry to say, only with poor results. I am sure I am making the knot right, but something usually goes wrong whenthe knot istightened.
Now I have decided to waste no more time on that damned knot and go with the old fashioned seine knotwhich stays on the exterior surface. I have no problem doing that knot, but I would like to ask on which side ot the wing the knot and cord should be. I would say on the underside, but I seem to have read somewherre that it is better aerodynamicly to have it on the upper side.
Allanswers are very much appreciated.
