• 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 working on my panel right now--have to decide what electrical monitoring instrument I'm gonna use. (Due to panel space limits, I want to try to get by with just one guage).

In a simple biplane---only electrics are radio, transponder, intercom, nav and strobe lights, and back-up fuel pump---which would be better to have---ammeter or voltmeter?

I've got an opinion---but I'll hold it until we get some thoughts from others.
