• 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.

uAvionix TailbeaconX, AV-20S, AV-30 gauges

I was intrigued by the uAvionix AV-30 display on Skippy's panel and did some research. uAvionix sells two multi-gauges, the 3 1/8" AV-30 and the 2 1/4" AV-20E. The gauges display way more information than a self respecting Pitts driver would ever use, but of interest, they can be configured to show just G, alongside useful stuff like timers and clocks.

What got my attention is the AV gauges can also serve as control heads for the uAvionix TailbeaconX, providing an all-in-one transponder/ADS-B solution. The TailbeaconX only weights 3.5 ounces, while the AV-20E weighs 5.5 ounces. That's an ADS-B out system weight of 9 ounces! I don't need (or want) the light on the TailbeaconX...however....

Going this route ditches the mechanical G meter gauge (1 lb) and the Trig ADS-B stuff (TT22 Transponder box, control head, and TN72 GPS, 1.7 lbs).

That turns 2.7 lbs into 9 ounces.

I also saw a video showing the built in warning mechanization on the MGL EMS-2, and could do without the red idiot light.

So, redrawing my panel plan, here it is with the AV-20E in place of the mechanical G meter and Trig TT22 control head, an iPad mini RAM mount on the right side, and no idiot lights.
