• 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.

Probably not too useful for most on the Biplane Forum, but just in case you have have an Apollo GX series GPS or GPS/Comm in your plane - or know anyone who does.....

I have an Apollo GX60 GPS/Comm in my Eagle. These GX series units are probably reaching the end of their life expectancy. I don't use the GPS much for navigation, but it provides the position update to my 406 ELT. The comm radio is really nice so I don't want to replace the GX60 until I absolutely must. The primary cause of death for the Apollo GX series units seems to be screen failure, and the screens aren't made any longer. The particular screen failure problem I encountered was caused by the embedded light sensor. The first indication of a problem with my GX60 was when bright sunlight would hit the screen and cause flicker, blanking and pixel loss. It became progressively worse over time until the screen was completely unreadable. If this is something you have experienced, here is a tip that may buy you some time. Cut a small (dime-sized) piece of dark reflective window tinting and place it over the light sensor on the upper left side of the screen. It is barely noticeable (see pic), and has solved the problem in my unit completely - hopefully for quite a while longer.
