GNC-300XL IFR GPS/COM

Seems I could get the EHSI plus an older GPS-comm for a little more
than a 430 with indicator alone.


You clearly haven't priced HSIs.

Well in my particular case, the radio I'm replacing is a narco with a narco
glideslope head that won't work with my other nav/comm (a KX-175B). So I'd
have to buy two heads if I wanted to fly a precision approach: one for the
new GPS, and one with a glideslope needle (I DO have a KI201C currently on
my KX-175B but, even if that would work for the GPS, I'd still need to buy
the annunciator, etc). I opted to buy just one head with a glideslope
needle and share it between the GPS and my nav/comm. En route, I certainly
wouldn't be using both at the same time, and I couldn't think of any
approach situations where I'd need a CDI for both. If you're not in this
particular situation then yes, it makes better sense to buy the MD-41
combination.

Mark:

With your setup, if you want to use MD-41, you still need a KN-72 converter to
convert KX-175B's composit NAV to right-left for MD-41, and you would not have
GS nuless you also get a KN-75 GS receiver.

If you want to share a CDI for both KX-175 & GPS, KI-209A is your best choice
because KI-209A has built-in converter & relay switching for GPS/NAV signals.
You still need a GS receiver like KN-75 to get ILS, and annunciators/switches
to control GNC300's arm, hold functions as well as switching KI-209A between
GPS/NAV signal by grounding a wire from KI-209A.

All these extra hardwares and installation make GNS430 a batter and not much
more $ choice. Been there & done that with KX-125, KN-75, Trimble 2000,
KI-209A, and MD-41 (I get GPS on both KI-209A & MD-41). I did my own
installation so I saved by using used first gen GPS, but if I need to pay
someone to install for me, GNS430 with single CDI will be my choice.

Actually the quote I got for a Sandel Install was slightly less than one
for an IFR 430 install a while back. Perhaps an older generation GPS comm
is more expensive to install than I thought? Did I miss something?

You can buy a GNS430 on eBay for $6000 and have it installed for $1000. I
did.

A King HSI will cost just about the same on eBay and to convert it to
Sandel will cost a minimun of $7000. You might get $1000 for the King HSI
indicator.

GNS430=$7000---used, installed
Sandel=$12000-----minimum, used equipment, PLUS installation


Karl

Is that an IFR 430 install? The quote I got was $14K for a new GNS-430A IFR
install with a new indicator. A separate quote I got for a new Sandel EHSI
with a new gyro system, installed was about $13K. For $1000 install, it
does not sound like an IFR installation???

I already had a King KCS-55A HSI installed, so I didn't need an indicator.

I also wrote my own POH supplement(boiler plate from Garmin) and did the
required flight testing(virtually nothing these days.)

All my avionics guy did was remove a KX155 and wire in a GNS430. My avionics
guy is a jewel(great with FAA approvals) and doesn't seem to mind installing
junk I buy off eBay. But then, I've done him a few favors as well.

What most people don't realize is that the Sandel is only an indicator. You
still need all the compass system parts from King, Collins, or others.

Karl

Yeah, the shop I got the quote from generally won't install stuff off ebay
without a substantial install premium. At the time of the quote, my stack was a
pair of MX11's a Nav122 and a Nav11, so it needed an indicator with the GPS,
plus needed moving stuff to make room for the 430. I've since replaced one of
the MX11's and the NAV11 with a KX155 and KI209.

I am aware the Sandel is an indicator only. The quote I referred to had a new
mid continent gyro system with it. The Sandel indicator by itself was under 10K.

Yea, and I think I forgot to include the cost of at least $1000 for an
indicator.

Robin:

I basically did what you suggested except I chose a garmin head rather than
the king head. So the extra parts I'm getting are the garmin head, the
KN-75 for glideslope, and an AmeriKing annunciator/switch. And you're
right, that does add to the cost, but everything included I'm still about
$2K shy of a new 430 install. I can't remember if I already mentioned this,
but I looked into the used 430s and couldn't find a 14v unit. I was advised
against using a 28v unit with a converter because apparently the converter
fails often.

If anyone has any experience, good or otherwise, with one of the 28v 430s
with a converter, I'd like to hear about it.

Mark, 14V units are always on eBay.

Watch out, there has been some fraud in the Garmin 4/530 sales. I'd only buy
from these guys or JA Air.

Please, give yourself an early Xmas present and go for the 430. You will
never be sorry. I've owned a 430, 155XL, and 155. The 430 is leaps and
bounds better than the XL series.

Karl
Thank me later!
