OK you G3X'ers out there - where are you putting the "stuff".  After reading the 4197 page instruction manual it appears that the best place for the magnetometer is in the wing tip, and the AHRS near the firewall.

The reason for the wing tip is to get it away from all the big wires and motors (eg., trim) and magnetic stuff.  The reason for mounting the ARHS forward is that it also has the engine monitor integral to it and the sensor probes have to connect to it.  Maybe on top of the tunnel?



What have y'all been doing?



I just got my GTX-23 yesterday and it appears that the best place for this transponder is behind the baggage compartment bulkhead, above the batteries, where I had originally planned to put the AHRS.

Hi Dave, 



The GMU is best placed either in the fuselage on the bulkhead behind the

baggage compartment wall or on the wingtip. We have a custom made mount for

either location so give us a call and we can get one on the way to you. The

Fuse location is nice and handy, but won't work so well if you have an air

conditioner in that same bay...otherwise we have dozens flying with the unit

in that location with no problems. The wingtip is nice as well, but only if

there is no strobe power supply or wingtip fuel tank. 



You are correct that the AHRS is best mounted either between the panel and

sub panel, or between the firewall and sub panel directly in front of the

screens so you can easily work on it without crawling around on your back.

The GTX can go in the back or in the front, no problem either way.



My 2 cents as usual!



Cheers,

I have located the GMU using the bracket Stein provides, on the 2nd bulkhead back from the baggage, the one where the static port is close to.  This puts it far enough away from the battery and the elev trim servo.  There are lots flying this way with no issues.  My GSU is mounted on a stiff tray I fabricated from .062 that spans the instrument panel to the sub-panel on the right as close to the right side as possible.  It is extremely stiff at that location.  I am installing a 3 screen system which will provide easy access to the GSU.The pitot static will go through the sub-panel using 90 deg. elbows.  I would not  mount it on the tunnel or close to the firewall due to possible heat issues and access.

Hi Bill,



Would you mind giving me your reasons for deciding on a 3 screen system?

Stein and Bill - thanks for the info and photos.  I'll put the magnetometer in the aft fuselage area as Stein suggests.  It helps to know that it works well there.  I like Bill's AHRS mounting and will do something similar.



I am also installing a 3 screen system.  My reasons are to have two in front of the pilot (one to aviate, one to navigate/WX/ etc.) and one in front of the co-pilot so it can be flown from the right seat.



An unrelated factor was that the price reduction on the G3X allowed me to get 3 screens for a lot less $ than a 2 screen GRT or AFS.

I would be interested to know what a G3X costs vs the GRT and AFS (At the same functionality)



Does the G3X have engine instrumentation? Do you have to pay an annual subscription for map updates?



I am not familiar with anything other than the AFS. 

 

I know things change faster than one can build a panel.  But a real point in time comparison with the features would be interesting!

Jim,



This is a little off topic so I will give a couple quick answers and then give a more detailed response in a new thread later.



Yes - it is a complete system including engine monitor and sensors.  It has synthetic vision, HWITS display, geo-referenced charts, approach plates, and airport diagrams.  With the GX Pilot it can do a complete coupled approach.  The functionality is about the same (as far as I can tell) as the GRT and AFS high end systems except it has built in geo-referenced plates and airport diagrams which the others do not.  The screens are a bit smaller but fit very nicely on a standard 10 panel.



I had the same question about subscriptions.  I have been told that for the G3X, the Jepp subscription that you need for the GTN-650/750 will work to update the G3X map at no extra charge.



Garmin now allows builders to make their own harnesses.



As I recall, the 3 screen G3X came in about $2500 less than the GRT/AFS equivalents.

The reason I went with the 3 screen system is that both my wife and I are pilots, we use our current plane for lot's of long cross country flights.  We intend to do the same with the -10.  It seems like the person on the right always ends up flying for a while on long legs, so the 3rd display will take care of that.  Also, our plan is to usually have the non-flying pilot take care of the radios, talking to center, looking at weather and navigating.  The third display will make this a lot easier.  The final reason is that my father, and building partner, just turned 87.  He continues to fly and pass his medical and BFR every year.  The only issue is insurance.  We have been told we will not be able to get any for him without me or an instructor in the right seat.  Those are the reasons for my choice of a 3 display system.

While the size of the displays are not as large as the AFS or Dynon, they fit very nicely in the panel.  I attached my cad image with JPG files overlaid on the panel.

I agree completely with Bill on his points. One thing not mentioned is the

cost of these systems is not in the screens so adding a third screen is

~$3,500.

All that being said there are a few gotchya's on the G3X and the 430/530.

The 430 takes over responsibility when on so an flight plan best entered

into the G3X is useless when the 430 is on. One must place a flight plan

in the 430 to drive the AP. I have no idea what the situation is with the

650/750. Regardless I understand that Garmin is planning to change this at

some point. On another note I personally prefer the D100 to the D10 as a

backup unit if space permits.

Just getting use to my dual screen G3x system in the 8A.

Robin,



The new update fixes this. I flew mine out today (formation with Scott). I can enter Flt plan on either unit and you can hit internal on the Efis and it uses it's own gps. It's nice to have the g3x on gps and the 430w on loc.

Robin,

When you find out how to update it let me know!  That drawback was a great one to fix!  Now hopefully ADS-b traffic and weather??

I just wonder, what the overall cost for such a system is:



G3X with 2 screen, engine monitoring all sensors, AP, the subscribption 

for air data, backup battery (?) and I guess a 430 is as a minimum 

mandatory for being able to display for navigation VOR, GPS and ILS as well?



Just to compare with the other producer of fine EFIS systems



Many thanks



Werner

While you're comparing systems, take a look at MGL ...... 

http://www.mglavionics.com/.

I'm installing two independent Odyssey systems but with only one RDAC, 

the engine monitor part.  It mounts in the engine compartment and only 

one signal wire penetrates the firewall instead of the huge mass of 

CHT/EGT wires.

Werner,

You can go to the aircraft spruce site and price the whole thing out.  You can call SteinAir and get a quote on such a system.  The system I have shown in my prior post will cost me $32K.  I purchased all of the radios used, although they were never actually installed in aircraft.  This saved quite a bit, but sacrificed the warranty.  I am doing all my own wiring, EE by trade.  So you can add $$ to have the work done for you by an avionics shop.  All of the systems are around the same amount within reason.  There are features of some that you may want that others don't offer.  Dynon is probably the least expensive for what you get, but is also the least capable system.  You have to do your own evaluation for how you intend to fly.  At one point I had a spreadsheet, but I can't seem to find it today.

Bill
