• 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.

Does anyone know why the dihedral on the lower wings changed from 2.5 deg to 1 deg [75 v 91 plans]?


I have also finally determined the angle of incidence of the lower wing fuselage brackets... they should read 0.0 on the digital level [tail is shimmed high by 1.5 deg], but both sides currently read 0.2 [trailing edges would need to drop slightly], seeing as both sides are the same, will this be ok? or should i grind off the rear brackets andadjust....
