• 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.

Flop Tube

In the Acro Sport 2 plans it shows the flop tube mounted 4 inches from the bottom of the tank and the tank 14 inches long. I plan to plan to make the tank 2 inches longer a total of 16 inches in length. What height adjustment should I make to the mounting of the flop tube to get the best out of it?
