• 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.

Forgive the basics here, just starting my research.

I understand that many BT-13's lost their lives after the war to donate their 985 to the Stearman dusters. Is this the genisis of the 450 Stearman, or is it a factory/millitary supported sub type?

Aside from the engine swap, what other mods constitute a "legitimate" (if there is one) 450 conversion? I suspect the 4 aileron mod is separate and distinct from the 450 mod?

What is the certification category for the 450 (or 220, for that matter) - do they carry a TC, or are they E-Exhibition like most other warbirds?

Many thanks
