Dear Listers,
This year's List Fund Raiser is still trailing last year by a 12% margin. If you
like the ad-free environment that is the Matronics Email List and Forum experience,
please make a quick Contribution to keep it that way!
http://www.matronics.com/contribution
I've been getting a ton of really nice comments from Contributors regarding the
Lists. Please read over some of them below and see if they don't resonate with
you as well.
Thank you in advance for your generous contribution to support these Lists!

Emacs!
I vaguely remember seeing these on some installed equipment.
I think these are a Kings Connectors KM59-13. I don't
recall seeing these very often in the coax cable version
but they're popular now for a bunch of fiber-optic
cables.
I've not yet chased down the installation specifics
but I'll bet they're VERY close to the venerable
solder-n-clampnut versions of the BNC connector.

Perhaps someone on the List can enlighten us
further. I'll keep looking.

That same connector is on the back of a King KI-214 VOR/LOC/Glideslope indicator.
In that application it carries the 350 MHz Glideslope signal from the antenna
(or diplexer), since the receiver is located in the indicator.

Hello, Matt,
I've been a user and supporter of your wonderful lists, primarily of
the AeroElectric-List, for years. However, although it has nothing
directly to do with your lists, I must say that as a long time Kitlog
Pro user, I'm still waiting for your promised update to the program.
You bought Kitlog Pro several years ago and more than once indicated
to me that an update was on the way. It would be so nice to have a
number of the not user-friendly features of Kitlog improved as we
have discussed in emails to each other. And I'd especially like
Kitlog to be able to handle more than one builder account in the
Expense Log section. The program already handles multiple builders in
the Construction Log section. I'm sure I'm not the only Kitlog Pro
user who has partners in their project who want to keep their dollar
contributions separate.
OK, now that I've got that off my chest, I'll whiz over and donate
again this year.
Hopefully next Spring we'll fly our Sportsman.

What's your budget for an antenna purchase? What
kind of airplane are you installing it on? Are you
willing to place the antenna for optimum performance
as opposed to least ugly appearance?
The well designed transceiver will function adequately
on about anything from a wet-string to a $2000 shark-fin
with a turbocharged flame job painted on the side of it.
ICom is about as capable as they come for building a radio
that works well. So the suite of antennas available
to you is pretty large. The least expensive antennas
tend to be not very robust mechanically while all
the $high$ products are very rugged but would not
perform so much better that you would notice a difference.
The going rate for a run-of-the-mill, 5-hole mount
vhf comm antenna is about $150. You can build an
antenna for about $15 in materials and a couple hours
fiddling in the shop. Are you installing on a metal
or plastic airplane?

Subject: | Contactor Failure |
Any folks had a contactor failure?
My understanding was that contactors are not failure prone. I understood
that was the reasoning behind inserting one between the battery and the
starter solenoid.
I had one fail the other day (actually it stuck in the closed position)
after 40 hours of use. It was an intermittent duty contactor installed
between the #4 welding cable from the positive battery post and the Skytec
starter.
If my engine doesn't start on the third blade, I release the starter button
to check what I've missed and try it again. When I released the starter
button, the prop kept turning. I quickly hit the starter button again
thinking it might have stuck. The blades kept turning. I turned off both
batteries and all fuel source. The blades had stopped by then (10 seconds) but
the starter was still engaged. Set the brake and ran to the hangar for
wrenches. I had to disconnect the battery to stop the starter. There was no
other way.
Did I design in a fault? Aren't most custom-built airplanes built with a
contactor between the hot battery and the starter? Should I have some
other type of disconnect between the battery and the contactor?

If I understand your system, you have a circuit from the battery straight to the
starter contactor.
Running the starter contactor in series with the master bus contactor allows you
to kill the starter with the master switch in the event that your starter or
starter contactor decides to run on.
Bob's Z designs typically have this feature.

Don't know what you mean by "failure prone".
All parts have service lives. The service
lives of all parts are subject to the stresses
of the installation combined with the effects
of manufacturing variability.

Does your starter feature a contactor/solenoid
combination that controls both power to the motor
while extending the pinion gear for engagement?

Does your starter current go through the battery
master contactor as depicted on ALL z-figures and
common to ALL type certificated aircraft?

Yup, the TC aircraft do it too . . . it's called
the battery master contactor.
As to the original failure. Permanent magnet starters
offer VERY high in-rush currents because the current
limiting characteristics of the series field are not
present. The device selected to actively control
starter current is not up to the task.
I was a participant in the deliberations that set
design goals at B&C some years back when consideration
was given to PM fields. For a several reasons, B&C
stayed with the wound fields. One reason germane to
your experience was the fact that battery internal
impedances were going down while stall currents of
"modern" PM starters was going up. This combination
predicted a potential for increased stress in contact
closing on the starter contactor.
If memory serves me correctly, the Skytec's built in
contactor is probably tailored to this extra stress
but it DOES exhibit inrush current issues of its own.
See . . .
http://www.aeroelectric.com/articles/strtctr.pdf
Suggest you rewire to eliminate the external, intermittant
duty starter contactor. Run your starter current through
the battery master as suggested in the drawings. Buffer
the inrush current to your starter contactor as suggested
in Z-22.
