Craig-
BM will send you the servos, custom servo cables,  and the servo driver box
early if you ask them- I have had mine for over a year, and I have not
finished paying for the entire EIFS unit.

        I have the BM EFIS one and Lite installed in my aircraft and I am
glad I chose BM for my installation.  Dave Bertram

        I forgot to mention this (not sure why this would slip my mind), but
I put ½ of my money down on the BM at Oshkosh ’04 and I am (cross your
fingers please) suppose to be getting mine next week or the week after.  It
really hasn’t been an issue since we didn’t need the box right away.  It’s
starting to become an issue only because we need the AP servos to mount.
There have been more “vocal” people on the BM website that order there’s
much later (Oct) and have gotten there’s sooner.  Squeaky wheel gets the
grease.  But I’m sympathetic of the “small guy” and sticking it out.  Plus I
feel this is a one time delay and the feature set it worth.

        Have any of you guys considered Blue Mountain Avionics?  They have
had growing pains 
 but I really believe the value is unbelievable and the
system works.  I am flying it now.

        Keith,



        I think you'll like the setup.  GRT was going through the usual
growing pains but they seemed to have gotten out of the gate and up to near
full speed at least as well as, if not better then BMA.  I do wish they
would finish up their ARINC 429 software so the vertical bug would drive the
TruTrak A/P.  I suspect they are being particularly careful about the
vertical commands being bullet-proof.  Something about commanding the plane
to descend to a lower preset altitude at a predetermined descent rate in IFR
conditions has a smell of liability associated with it.



        Steinair seems to be a safe choice.  He seems to be
present/participates on both the RVList and AeroConnection websites and no
one seems to throw brickbats at him.  Some of the things he posts even makes
sense...which puts him ahead of many, if not most.



        I think you'll be happy with you choice.  If I were to make the
decision again, I'd do the same (though not at the same place).



        Chuck

        Chuck,



        I agree on the big map display.  As I wrote, I'm planning to use the
upper for PFD, lower for moving map.  I had planned to swap out the moving
map display for the graphical engine display at those times when I want to
look with more detail at engine parameters than the display on the EIS
provides.  However, the split screen on the upper is a pretty good idea.



        I just got a quote from Stein Bruch (www.steinair.com) on a dual
display GRT EFIS & EIS system for my Velocity.  He basically confirmed that
you have to use two multi-function displays.  The good news is that my
configuration (including fuel gauges, fuel flow transducer, pressure
transducers, thermocouples, OAT, etc.)  came out $435 less than GRT's list
prices, and includes free wiring harnesses!

        Keith,



        I pretty much dedicate the bottom display to the engine data because
I take my map stuff off the Garmin 480/MX20 combo.  But if you use the lower
display for the map, then you can do the split screen on the upper and
display the PFD left and major engine data (RPM/MP etc) on the right.  The
PFD, even on the split screen, is still plenty big to show you a good
horizon, airspeed and altitude.  When I've played around with the map
function on the GRT EFIS, I didn't care for the map function on the split
screen.  Maps are all about context, hence the map on a split screen is like
trying to drive a car looking through binoculars.....okay, so you've never
been stupid enough to try that, but you can know that it's not easy because
you loose reference to the surroundings, which is what a map on a split
screen does.



        In short, I don't see any advantage to a dedicated screen, unless
there is big $avings.



        Chuck

        Thanks, Chuck.  I had planned to mount the EIS 6000 in the panel
anyway, so when I'm using the lower display for moving map full-screen I'll
still have the basic engine information displayed.



        I had intended to use a "PFD only" dedicated display for the top,
but l need to confirm whether or not I can mix a multi-purpose display unit
with a single-purpose display.

        Keith,

        I have the dual GRT EFIS and both can be selected for PFD, MAP, ENG
or split screens.  I personally like the PFD on the top and all my engine
stuff on the bottom.  There is a soft-button that you can 'lock' either unit
to PDF, but I don't see any advantage.  The buttons are big enough that they
are easy to locate and push, even in turbulence and without the problem of
inadvertently hitting the next door neighbor (button).  I also have the EIS
6000 LCD screen mounted on the panel.  If it wasn't for infrequently
resetting some value, I wouldn't put it on the panel as it just eats up
space.  Unfortunately, when fuel is loaded, it is inputted thru the LCD
unit, not the EFIS, so you need access to the rectangular LCD computer
unit--may as well mount it.



        What would be great would be if the EFIS and EIS talked both ways,
so the fuel could be added thru the EFIS screen, but I think the
conversation only goes one way--kind like some relationships.



        Chuck

        Hmmm. .   I talked to the EFIS sales guy at Grand Rapids about my
intent about 5 months ago, and he said, "no problem".  I'll have to look
into this further.  Of course, my situation might be somewhat different
because I'm using their EIS 6000 for engine monitoring.  I agree that
flexibility is nice, but it also leads to more complexity.  Then there's the
$500. . . .

        I'm also planning to use the GRT EFIS.  At this point I'm planning a
dedicated PFD on top, with a multi-mode Moving Map/Graphical Engine Info/PFD
under it.  My thinking is that I will always want the primary flight
instruments right in front of me, but if that unit goes south, I can use the
lower GRT display as a backup.  The lower unit will usually be in moving map
mode, except during leaning or evaluating a potential engine issue.  The GRT
EIS 6000 will provide engine indications the rest of the time.  My backup
moving map will be the GPS (both panel-mount and handheld).



        I have the dual screen GRT setup, and also intended one as dedicated
display since I have a separate engine monitor with will not display on
their screen.  Apparently, you cannot have one dedicated and one not
dedicated with the two displays, and they charged me the extra $500.  When
questioned, they refunded $250.  I think it is good to be able to use either
screen for any display.
