If you look forward to checking your List email everyday (and a lot of you have written to say that you do!), then you're probably getting at least $20 or $30 worth of Entertainment from the Lists each year. You'd pay twice that for a subscription to some magazine or even a dinner out. Isn't the List worth at least that much to you? Wouldn't it be great if you could pay that amount and get a well-managed media source free of advertising, SPAM, and viruses? Come to think of it, you do... :-) Won't you please take a minute to make your Contribution today and support these Lists? http://www.matronics.com/contribution Or, drop a personal check in the mail to: Matt Dralle / Matronics 581 Jeannie Way Livermore CA 94550 USA I want to say THANK YOU to everyone that has made a Contribution thus far during this year's List Fund Raiser!! These Lists are made possible exclusively through YOUR generosity!! Thank you for your support!

The problems or rather limitations of fibreglass are: 1. Not as rigid(stiff) as aluminum so will require reinforcement to reduce localized bending. Ie, around openings where racks attach to the panel face. 2. holes that are made after fabrication break the glass fibers and are subject to tear out are cracking. 3. Requires a mold to make the panel thus additional time and effort to fabricate. (typically the panel needs to be removable to facilitate construction and maintenance). Not impossible but not very practical unless there is some compelling requirement.

Very strong and has no problem supporting any instruments. But, it is a lot thicker than aluminum panels, and may even be a bit heavier. Some have replaced the fiberglass/plywood panels with aluminum, leaving a narrow lip around the edges to mount the panel to. I like this idea, and probably would have done it myself, but just wanted to follow the plans when I was at that point, and hadn't heard of this idea then. It would make it a lot easier to access the rear (forward!) connections of the instruments, as removing the panel and dropping it down would be a lot easier than trying to fish around in the min-hellhole between the instrument panel and the front fuselage.

The bottom one is not a problem, but the top one could be for my RV-9A. I hate the look of any antenna on the top profile of the fuselage. Thinking ahead for when this becomes a requirement, a standard rod style or shark fin style transponder antenna would fit nicely under the vertical stabilizer fiberglass tip fairing and would be mounted to the vertical stabilizer top rib. The top rib is aluminum and measures 2" x 7". I understand the ground plane in this location is rather small. Would this location work at all? -------- RV-9A Firewall Forward Read this topic online here: http://forums.matronics.com/viewtopic.php?p=492892#492892 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
