• 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.

I'm thinking of switching to fine wire plugs. Currently I run REM37BY and going to switch to UREM38S. Anyone happen to know the actual length of these plugs? I have a tight cowl so wondering how much longer they are.

There is some interesting stuff published on other forums and sites about the failure rates of Champion plugs of late so I think I'll try Tempest next time around.

Cheers,
