The new pricing and AP put the GX3 system close to the price of some of the other EFIS systems I am considering. I do have a couple questions.
1. What is the cost of the sensors for the EIS? It says "starts at $299", but the link does not work to get further info.
2. Looking at the list below, what else is needed to make this system complete? (for day -VFR only)
GDU 370 Display
A/P Servos
A/P Control
AOA-Heated pitot
GSU Second ADAHRS (if using 2 GDU 370's)
GMA 240 Audio Panel
SL 40 COM
GDL Uplink - Weather - Traffic
GTX 23 ES Mode S Transponder
EIS Engine Sensors - Lycoming O320
Thanks for the help. I may have to re-consider my selection. I had narrowed it to the Skyview or the GRT. It will be interesting to see all the units at SNF.

The servo is a definite no. There are some major technical differences between the Dynon servo and the GSA28.
I was told that the Dynon AOA probe is not supported.

I will no longer need a GX Pilot as the autopilot is integrated into the new servos but I could add a GMC305 for added features.
Will my Tru-Trak servo brakets work with the new GSA28 servos?
The GMU44 has been replaced with a GMU22.
I will now use a GDL39R since I am remote mounting anyway.
Angle of attack in integrrated if I desire I only need a GAP26?
I don't see a new manual yet?
Good thing I haven't started a harness yet.
Did I miis anything?

Hi Mark - You covered the bases pretty well.
First, the GSU 73 will absolutely still be supported for those who have one, or decide they want to buy one. However, as you pointed out, the new black boxes are lighter and less expensive - thus is the nature of technological progress.
The GAP 26 is a combination pitot/AOA probe (heated or unheated) which doesn't have any special smarts on its own. To have angle of attack you plumb the pneumatic tube from the AOA portion of the GAP 26 into the corresponding AOA input port on the GSU 25.
The GMU 22 and GMU 44 magnetometers use identical wiring and have the same physical dimensions and performance characteristics, so no changes necessary there.
Our autopilot servos use the same industry-standard mounting pattern as used by various other manufacturers. They are smaller and lighter, but they should still bolt into the same holes. For those who prefer a completely standalone autopilot, support for using third-party autopilots such as the Trutrak GX Pilot with your G3X system continues, including the ability to mix and match the Trutrak and our new GMC 305 mode controller as mentioned earlier in this thread.
As you pointed out, the installation manual is not available quite yet since these products will not be shipping for a few weeks, but we're happy to share information here in the meantime.

Hi Bob,
We have not tested our AOA system with anyone else's probe design, so we can't say whether or not this would work. We can only say for sure that it's designed to work with our probe.
Our system is compatible with certain third-party autopilots, including the Trutrak GX Pilot, but it does not plug directly into third-party autopilot servos. Hope that clears things up!

You said Day VFR so:
You don't have to have the GMC305 but I would highly recommend it based on my experience in the past with dedicated controls.
You don't have to have the heated version of the GAP26. They are releasing a non-heated version
You only must have one GSU25 for VFR but you can add up to three if you want, one GSU25 can be shared with up to three GDU screens. For the first one, get the package that comes with the GMU22 & GTP59.
Just a suggestion...Go with the newer GTR series radio, the SL40 design is quite dated...
You will need the GEA24 as well if you want to add EIS information to the system.
Here is a link to the Garmin Sensor Price Page...

Click here to see prices for G3X engine sensor kits. The list price for a four-cylinder Lycoming kit with fuel flow is $999. (These are the same sensors we have been using all along, by the way, no changes there)

The above system should work great for VFR flying, although I should point out that without an IFR-certified GPS navigator, you will not be ADS-B Out compliant after 2020 given the way the rules are currently written.
By the way, since the GSU 25 (and GSU 73) ADAHRS units live on a shared bus, there is no strict relationship between the number of display in the panel and the number of ADAHRS units supported. Any G3X system with any number of displays can have one, two, or even three ADAHRS installed. We do try to steer people who want a full-featured system, such as the one you described, towards a two-display setup since it offers more glass area and additional places to connect serial devices.

Brian, you are a faster typist than I am! Maybe I should go home and let you take over.

Matt and Brian,
Thanks for the info. I did have the A/P control listed and the 2 servos. I like what I read about the AP system.
I would also like to have 2 G3X screens, but may have to wait for a second one because of costs. I updated my list and I think I have included everything.
GDU 370 Display $4,375
A/P Servos (2) $1,598
GMC 305 A/P Control $750
AOA-Heated pitot $300
GMA 240 Audio Panel $845
GTR 225 COM Radio $1,800
GDL Uplink - Weather - Traffic $800
GTX 23 ES Mode S Transponder $2,200
G3X Sensor Kit, 4 Cylinder Lyc/Cont (K00-00512-00) $1,000
Optional Carb Temp sensor $75
Total - $13,750+-
Second GUD 370 and ADAHRS $3000+-
As for the ADS-B out, I imagine I would have updated my panel by then.
I look forward to seeing the units at SNF.

I'm just getting booted up on the left coast this morning, and you two guys already have this at four pages of posts - no matter who is answering, I think thre is a LOT of interest.
I only wish we had room in Tsam for the new 305 control head.....
