| Subject: | Value of the List... |
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?

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!

| Subject: | Re: Fiberglass instrument panel |
Fibreglass aka polyester and glass can be strong enough to support most
panel mounted avionics. 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.

| Subject: | Re: Fiberglass instrument panel |
The panels in our Long EZs (if built to plans) are made of fiberglass
laminated on plywood. 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.

| Subject: | ADS-B Diversity Antenna for Canada |
Sometime in the future (already delayed at least once) Canada will require ADS-B
with diversity antenna. 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?
