OK, I found the manufacturer for the connector, they're about
an hour drive from where I live. Now I know why these plugs
are so expensive - they're made in Switzerland! :-)
http://www.lemo.com/
The price for the raw plugs in units of one are about USD 40
each. I think I'll just stick with the batteries for now.

I have no personal knowledge or experience with Dynon's
products. The feedback I've heard on the 'net about their
mini-efis has all been favorable. If they've added a systems
readout to their stable of products, I have no reason to believe
that their acceptance in the marketplace will be any weaker
than for the mini-efis.

I think your risks are low. Systems monitoring is 1/10th the
effort of sensing, deducing and displaying platform dynamics.
Systems monitoring is a cake walk for anyone who can do well
with the flight instruments.

Sorry, not to any greater degree than I've outlined above.
If it were my money, I'd sure give them a whack at being

I am looking at the diagram of Bobs homemade glideslope antenna.
It is not clear to me whers and how the coax and shield attach to the two whiskers.
It will be going in a composite... do I need a ground plane???? If so how is this
placed relative to the antenna?
Can the Nav antenna serve also as the Glideslope antenna?
Thanks

No way to know right now. Depending on how the intercom
is wired within, the possibility of a ground loop exists.
Wait until you've flown the airplane and see what turns
up. Your astute observation and consideration of the
possibilities will point to potential remedies if something
pops up.

Yes, there are couplers you can purchase to steal a

I have not flown mine yet but the installation setup is a piece of cake.
The premade wiring harness makes this so easy.
One minor error is the oil temp is way off...This maybe a Dynon problem
or a bad temp sensor...I will be investigating this in the next few
weeks. Dynon has given me some pointers.
CHT's were all spot on accuracy wise
Great company to deal with and I like the screen swap feature and it

I was a passenger in an RV when Dynon was testing their new programmable
split screen EFIS/Engine monitor system.I was very impressed with the display
and the multitude of options for display pages.
I use the smaller Dynon EFIS which is a great instrument but this new larger
model really impressed me.

Obviously the "weak" link is that heatshrink offers less grip on
the pins than do connector bodies . . . but it is surprisingly high.
I just tried it with some clear heatshrink and found that tension
on the wires stretched the shrink and the pins did
not slide inside the heatshrink. I put several pounds
of pull on it causing the pins to disengage slightly but when
I relaxed the pull, the shrink slowly returned to original
length and full engagement of the pins.
Do some experimenting with the materials you have. Odds are
it will be fine.

OK, maybe I slipped once or twice . . . :)
The rocket is teaching me lots of lessons. Like: Don't start the engine

wiring in the radios will catch some, but not all voltage spikes, fuses

Regarding the Bose connector- Don't forget the need to utilize your headset with
your back-up hand held com radio when the panel mount croaks. It happened to
me near Northway, Alaska when my Garmin 250 XL display went blank taking the
GPS and Com functions with it. The return trip to California was a non event with
the hand held Com and GPS units that I carried (thanks for advice on the redundancy,
Bob). I would anticipate that a Bose connector interface with the
hand held for mic and phones is possible but the power for the ANR might require
a dedicated battery pack as part of the interface. Here's a design challenge
to create something elegant to stow with the hand held.

The diagram we've been discussing is Figure 13-13 in the
'Connection. Finding someplace to mount such a beast is the
hard part. I think I'd go for the coupler approach. Or, if
you have a fiberglass airplane, try sticking an 8" piece of wire
into a BNC connector and let it dangle out the back of the
GS receiver. When on the runway centerline, glideslope and
localizer signals are huge. You're looking right down the
"barrel" of a 5w transmitter from a couple miles away max.
A wet string would probably get you a good enough signal.
If a compromise antenna doesn't work, go for the coupler
from http://www.chiefaircraft.com and others. Looks
like this:
http://www.aeroelectric.com/Pictures/Antenna/CI_507.jpg
I'd much rather install a coupler somewhere than try
to find a 'nice' place to mount a stand-alone GS
antenna.

It works great. I learned that trick from Bob here on this
list, or in his book - I can't recall which. It's a bit more
expensive than soldering, but much faster and neater.
