Has anyone yet seen/touched/installed one of these new electronic horizons? Aircraft Spruce have them online for $2500.



Would like to hear from an early adopter before I plunk down my cash.

For the cost of that unit, you could install a Dynon EFIS D100 or D10A. 

This gives you an electronic horizon AND, airspeed (true), altimeter, G 

meter, Mag Compas, encoder, and optional autopilot.

BUT..if you don't want to go thru a major panel mod like installing an EFIS



Take a look at this little baby for half the price.   With the GPS, you have digital heading info....nice little unit.

3-1/8 ADI w/ GPS and battery backup is $1345.  Just don't know if it works inverted....I have one of the 2-1/4 in my CJ as a backup to the EFIS.

Having flown behind Craig's TT ADI, I can give it a big thumbs up.  In my opinion, to go with a old school (even electric) instrument that is twice the money makes zero sense.  The MTBF on this solid state stuff is outstanding and overall a significantly better value. 



Put it this way.  After flying behind the TT ADI, I exchanged the standby ADI in my Legacy for the TT.  The original one in my Legacy came out of an F-16.....

Thanks for the feedback guys. The reason I'm looking at the new RCA2600 (which is, incidentally, fully solid state)is as a replacement for my Russian horizon which is becoming unreliable. 

I need my replacement ADI to reliably survive continuous acro and be reliable enough for a climb through/descent below cloud to VFR conditions before/after an airshow: this is NOT for serious IFR.



I looked at the TRuTrak, but was put off by its use of processed vert speed for pitch information, which, I would have thought would make it very 'twitchy' for stable flight, as I may have up to 4 aircraft formating on me during a climb thru cloud. 



So the question is: is the TT reasonably pitch stable, and can it handle plenty of acro and still be stable afterwards.



I know there are a bunch of nice EFIS boxes out there, but I want to retain the a/c's vintage character panel.



Appreciate the help.

Mark,



Looks like a cool instrument.  I'd contact the mfgr.  My experience is that most EFIS units will not keep up with acro (not intended to) but the good ones I've flown behind will reset well.  Seems like it's a preference thing...for that money you can get a Dynon.  I don't know how much of the vintage look you'll retain with the Allen being a screen, but that's your call.  Think hard about the Dynon....it's a great unit, good support, and much more capable.  It keeps up with the roll rate of an L-39 and only after some serious maneuvering does it get "lost" at all.



Hope this helps,



Barry

Mark,

Look at Dynon D10 A also. I have taken my 50 IFR with that unit. It is

stable through an entire acro routine especially with the remote gyro

installed. It fits where the RU ADI is now quite nicely. You will have to

make  a back plate to mount it up to since it is filling a approximate 5

inch to with a 3 1/2 in instrument body. The EFIS part covers the ADI hole

completely when mounted. Basicly, it is 9 instruments in one. I keep all of

my other "vintage" YAK instruments in the panel and use them. I did couple

it to my Garmin 430 for the HIS function. Since I am using the D10A unit,

you have to toggle between the HUD display and the HSI. The but is that on

the heading tape at the top of the screen it includes the GPS heading bug

that you programmed in with the GPS heading track on the Garmin. It will

work with the 430, SL 30 (which give you ILS function too). With the next

software upgrade, they will give you the ILS ladder on the HUD screen as

well as on the HSI screen where it is now. This same unit with the 5.0

software upgrade with drive their 3 axis autopilot.

As you can tell I have been well pleased with my unit(s). Talk to Dave

McGirt also. He like I had some teething issues that were worked out by

installing the remote gyro. After that it has been pretty flawless. It is

not obtrusive in the panel and truthfully, when the ADI in my 52 goes TU,

I'll put one in it too. That is unless Emperor Obama drives us all broke.

Doc,



Do you by chance have a pic of your panel with the Dynon fitted?

Mark:   Here are some photos of the Dynon I put in my 52TD in the front and 

back.  It is Gucci!

Mark,

 A few years ago I was looking for the same solution and this is what I came up with:

 There are several companies out there who have in the past made aerobatic horizons for use in Citabria and other aerobatic aircraft.  These units seem to hold up well and would suit your needs I think.  How ever they are air driven. Most are vacuum, a few are vacuum OR pressure.  The options to drive it are few, venturi, electric stand by vac pump, or perhaps scavange some air pressure off the aircraft pneumatic system.  Either of these will work.  I chose to go with a 28 volt Airborne stand by pump.  Unfortunatly I sold that aircraft before I ever installed so I cannot tell you "the rest of the story".  Both units now sit on my shelf, $1500.00 takes them both.  The Airborne pump is factory new, the AI is used.
