• 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.

Can anyone let me know what they have used successfully for heat/sound proofing of the firewall - and also whether this is even necessary?

I have seen most pics of completed Pitts just appear to have a blank firewall, but it's often difficult to see as they are cockpit photos, and it's pretty occluded - so they might have something there that I just can't see.

What's the generally recommended practice ?
