• 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).

MySkybolt under construction has 3/8"motor mount bolt sizeat the firewall. I've noted that some folks suggest using 7/16" bolts.
I'm installing an IO540 325 HP motor. Do I need to be worried enough to change out the bushings/bosses on the fuselage?
