• 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 $29.95/year 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).

what locks the canopy down. Just two spring-loaded shot pins going through an adjustable tie-down lug. I will cut holes in the outer skin to allow one leg (handle) of the shot pin to protrude out of the plane, thus it can be opened from outside. To keep the shot pin from closing notice the cylindrical protrusion on the bottom. Housed in that is a ball-detent that makes the shot pin resist the spring until the operator actuates it
