• 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.

Just came across this and remembered a Hatz that crashed a while ago in the Midwest. The analysis only goes to 4.1 Gs on the rear spar. i pulled 6 Gs
in a busted roll and split S so fast that it was over before my legs started shaking. i wish they had listed the spar sizes so we could compare them to the other biplanes.
Go to the new Hatz home page and halfway down on right is the analysis.
