• 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.

Somebody tell me why using an air spring instead of a stack of donuts is a bad idea, assuming I can make it fit.

As an example, Goodyear has an air spring, 1B6-538, with an internal bumper and a top load of 22oo lbs, and a usable stroke of 4.8 inches. The max diameter is 6.5, which might work at the top of the charger gear setup.

These guys have them for $117 each: https://fluidpower.processcontrolsolutions.com/goodyear-air-springs/. It has to be a better solution than the donuts or a stack of spring washers.
