In my case, the strobe system had less than 50 hours of intermittent
use when it blew a 10 amp fuse. Some of the others also blew fuses.
But, in several other situations, the fuse/circuit breaker never
blew, but the switch showed signs of overheating. Bob, and others,
are hypothesizing that the strobe system cycles cause repeated inrush
currents that don't blow the fuse, but which produce overheating of
the switch. The overheating sometimes results in the switch shorting
out which does blow the fuse. All of the failed switches so far are
Carling 700 series switches. A more robust switch seems to be the
short term fix.

Bob knows far more than I do, but from this side of the computer I think
the inrush current for a single supply system must be higher than the
switch likes. How many hours are we talking here??? What size fuse???
There may be a clue there.

This is really odd! The switch is designed to short ......

I googles 'carling 700 switch' and got:
Rotary /switch Carling/ Technologies. /700/-Series: four position single
pole rotary /switch/; 1 to 4 amp, 125 to 250VAC; self-cleaning wiping
contacts; *...
*Which confuses me more since this isn't really a rotary switch
application ..... what am I missing??? And it's only rated at 4 amp.
AC though. I never knew exactly why, but AC rated switches aren't
supposed to work as good in a DC environment.
> A more robust switch seems to be the short term fix.
If we're really talking about the same switch, I agree.

| Subject: | 121.5 MHz ELT termination |
Hi Listers,
I have noticed a few hints of this on the list over the last year but never
really knew (or obviously paid attention) to the reasons. A few days ago I
received a post card from the NOAA informing me the Satellite Coverage for
121.5 MHz ELT's will end on February 1, 2009. It further indicates in order
to receive Satellite coverage I would need to be operating on 406 MHz.
Does this mean there will be a mandatory change of ELT device in order to
maintain my AW? I realize it would be near useless to continue with the one
I got if I don't change it. The question is more about what the
requirements are going to be. I also noticed just a week or two ago where
someone was purchasing a new unit at something like $895. This is about
twice what I remember paying for my current ELT that works perfectly. What
are others doing here?
I really hate this! That is my fuel budget for several months.

"Satellite" coverage ends. Not all monitoring of 121.5 MHz
406 MHz ELT not now required in USA. Check AOPA or VAF
for recent discussions.
Spend that money on fuel for now.

Tim: I am with you as to the expense, but yes, AOPA has told us
for the past year, the change and explain all the details...
What we do we the old unit...I wish some one could use them,
The reality is we have to get the new unit, otherwise we will not
have any communication incase of accident etc... I better star
saving for the $800 or so...

==================================
I have the older ACK E-01 ELT and their new compliant ELT E-04 that uses the
same panel mounted control and will fit in the same tray is going to be out
in a few weeks. The retrofit kit is going for MSRP of $560. Maybe ACS will
discount it slightly so perhaps it's worth calling them to see once it is
released.
I will probably budget mine for Q1CY09. My suspicion is that once their new
design and qualification investment is recaptured they will deal on these,
but it could be a few years.

There are no regulatory requirements to purchase a new ELT at this time.
Our ELTs are still perfectly legal, we just need to be aware that
satellites will no longer be listening on 121.5. If our ELT is
triggered, responses will be based on either aircraft monitoring 121.5
(nearly all commercial aircraft do so) or monitoring by ground stations.
The satellite-based ELTs are obviously superior to the 121.5 only units,
and each pilot must decide how important it is to have the latest ELT
technology. But the FAA has left that decision to us.
Canadian pilots MUST make the change to the 406 ELT.

Thanks everyone, I will monitor the prices and keep what I got until I am
more comfortable with the price. One additional question if anyone knows.
I almost always fly with flight following. If for some reason, I dropped
off the scope, would they pin point that spot and call emergency or would
they just say: "oh, must have lost him" and cancel the squak code? I would
hope I at least had time to notify them I was in trouble but you never know.

Tim, if you want to learn more about an exciting enhancement to aircraft
tracking, check out the APRS forum on the VansAirforce forum:
http://www.vansairforce.com/community/forumdisplay.php?f=104
You can read about the installation of an APRS tracker in my plane:
http://home.hiwaay.net/~sbuc/journal/tracker.htm
And the August issue of KitPlanes magazine has an article I wrote about
aviation APRS.

WRONG!!!!!!!!!
I have no intent to get a 406 MHz ELT at this time. I have an unreliable
121.5 MHz ELT.
I have a 406 MHz PLB (GPS enabled)
I intend to get an APRS system.
The later two offer better "services" that the 121.5 MHz ELT in my opinion.

You only need 406 if you want to fly in Canada or parts of Mexico. Not
required for US at this time.

| Subject: | My Interpretation Of Tip Installation... |
Dear Listers,
Today marks the completion of my RV-8 Tail including all of the
fiberglassing and tip installation. I had asked the List a while
back about filling the backs of the tips on the Vert/Horz Stabs and
got some great feedback. I used some hard foam and built a "dam" and
glassed the inside then rapped the outside with tape and filled with
resin/flockedcotton and then sanded it down to the right
size. Worked great and the next time I could do the whole thing in a
couple of days.
Rather than glassing over the whole end of the surface onto the
fiberglass tips, I opted to just mount using screws and platenuts and
only glassed AL-to-tip on the Elevator counterbalances where
necessary. They came out very nice I think with minimal fuss and
muss. Since the Rudder bottom and Fin Top had to be removable for
access to wiring, I decided that I wanted everything to look the same
and so I used the screws and platenuts throughout. Really didn't add
that much weight and allows for tip removal down the road without
paint damage.
The mount for the VOR/GS/LOC antenna on the Vert Stab came out very
nice I think and is very solid.
I definitely learned a lot about fiberglassing in the last couple of
weeks as well as gel-coating.
Lots of pictures attached.
Best regards,
Matt Dralle
