• 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 looking at a Skybolt to buy, and I have a couple more questions. 1. Should the flop tube be replaced at intervals, and if so, how many years? 2. It appears that the aileron slave tubes are not quite lined up with the air flow. The front is inboard of the back. He has put what appears to be a string under plastic tape length wise on the inboard (low pressure side) of the struts. It appears to be there as a "spoiler". Any thoughts on this? Am I going to have to rebuild the struts?
Thanks for your expertise,
Daryl
