I've revised the mounts slightly. Included the pilot holes to mark the corners of the panel for cutting, and moved the mounting holes around to give 1.5D minimum material around the holes (on the mount and the panel). The mount fits between instruments on a Mooney, and above an HSI if installed. Aerodon

I'd look at the max pulse / maxdim replacement units. Gives you a chance to get rid of some old wiring, with correct paperwork and replace with modern technology. Don

And I've also gone the other way and put together packages like this: GTX345 with built in encoder GNS480/GNS530/GTN750 I highly recommend the built in encoder - it reduces the amount of cross wiring, and you will save a lot of money in the long run with calibrations. And I highly recommend the GTX345 for all its features and its long term compatibility. But it is going to be a $6k installation, who would have though a few years ago we would be taking about $6k transponder installations. Don

nfonville, I have recently installed a GTX33ES with a GNS480. Even though its a remote unit, I used the flat tray and installed it in the RHS stack in a C172, and it gets covered by the RHS overlay. It's a little triangle of wires: Arinc and RS232 wires between the GKNS480 and GTX33ES. Encoder to GNS480 for altitude Encoder to GTX33ES for altidude GTX33 to audio panel and power and ground. I used a transcal encoder with 2 serial outputs, and powered it from the GTX33ES for a nice easy install. I used the old transponder antenna, but installed new RG400. A already had a GLDL39-3D for ADSB in. I have a spare GTX33ES if you are interested, and would take your GTX327 in trade. And I would recommend this setup if you want to stay in the $2-3k range installed (with some of your own time). Don

Now that TJ has sold his 730, here is another one with the latest software. $1200 outright $1000 with working EDM700 in trade I have all the parts in hand to make this into a full system, just contact me and let me know what you have installed. Don supercub180@gmail.com

Yes the 730/830/4/6 is all the same display. It will recognize the transducers installed, and forget the FF transducer if you don't have the FF switch installed. It will recognize 4/6 cylinders automatically, but you have to set the #cylinders so that RPM reads correctly. Aerodon

TJ, I have the remaining parts in stock to make your system complete. Don

Busy replacing 4 with CiES for a customer now, may have some working ones coming out. Interfacing to EDM900, so should be good. Aerodon

A little overstated. Highest time DC3 - 91,000 hours. 747 - around 135,000 hours. I remember reading about Braniff's 747 spent 10 years of its first 12 in the air. 20,000 hour 172's and Cherokees are not unheard of. 7000 hours should not be an issue, but a lot can happen in that time. Rather than making mundane statements about design flaws, I have no doubt this accident will be thoroughly unwrapped, and we will all learn from it. IMO, Cessna has done a good thing with the SIDS inspections, and I can see similar inspections being applied to other manufacturers. Aerodon

Try a few starts, or start again, do a 'reset limits' and see if that helps. Aerodon

Oh, I would't count on the manual matching the software / hardware. The later model EDM700's also had a RPM display, so would need the option to set the number of cylinders to match the mag/rpm setup. I don't have one on the bench to test right now, but I can assure you that I have seen numerous different setup lists, and sometimes some weird behaviour. More than once I have taken the trouble to send documentation 'errors' to JPI to forward to their document control, and yet the errors persist in subsequent prints. Aerodon.

Iain, I see you still have it on the bench - you need to plug it into a 6 cylinder harness and then it will recognize all 6 cylinders. Don

Iain, don’t give up yet. It might take three or four power cycles to recognize the 6 cylinders. And try putting the FF switch in different positions before powering up. Finally, get into the second level of programming (factory limits), and see if there is a 4/6 cylinder setting like the EDM800’s. Aerodon

And I have a couple of EDM700/800's that I could sell at a very reasonable price. I assume you have wiring in place, just check that it is JPI and not EI? Don

Brad, I think Rev 2.0 pictured above will fit - I can send the template to you to try. I'd like to leave a bit more material around the 6 mounting holes, but it does meet the specs that Garmin call out in the installation manual. Remember that the final is made out of 0.093, so its pretty sturdy. The hard part will be cutting the rectangular hole. Also, remember that this plate is about 3/8-1/2" behind the panel, so i don't think it will interfere with the NuLites. Don

Warren, You neglected to tell us this was the AOPA giveaway plane in 2001. Nice, how about the panel pictures, I'm sure its nice. Your sack is still very capable, heres what I would do and why: 1) replace GX60 with a GNS480 to get WAAS. The comm connector is identical, and depending on your indicator, most of the nav will be the same too. Lots of labour saving, and it will cross talk with your SL30. Sell your GX60 while it still has a good screen. 2) Replace your SL70 transponder with a GTX345 or 345R. The GNS480 will provide a position for this, and if you need a little more panel space, go for the remote version. 3) Once you start changing audio panels and mixing G530's with other avionics, you may as well start again with a GTN750. Don

I would do an Apollo SL15 audio panel / intercom now - not a big deal when interior is out, and more or less pin compatible with your KMA24. Then GTX33ES paired with your 480 to get ADSB out. Easy install if interior is out. If you have more money, then do a 345 or 345R, Aerodon

Bump this to the top. I have two systems ready to go, so can do the following combinations. Have various length antenna cables, let me know what you need. Send me an email for pictures. Aerodon supercub180@gmail.com System 1 - Used processor, used antenna (scuffed), used gasket, passes all internal tests. $2495 System 2 - Used processor, new antenna, new gasket, passes all internal tests $2950 System 3 - New processor, new antenna, new gasket. Made in 2011, never opened. $3950

And here's my EDM900 flush mount. I made all three styles - two screws above and below, two on either side, and the standard 8 hole JPI style. The JPI mount takes up a lot of space, and when you start trimming you can loose two or more mounting screws. I think I will try using the G5 style mount in the future, with the screws location chosen to match the neighbouring instruments. Aerodon

Here is Rev 2.0, I moved the 6 mounting screws closer to the G5 and trimmed the bracket to provide space for the adjacent instrument. But standard instruments can be as close as 1/4", so this might still be too big?

Any have a Century 21 wiring diagram - helping a friend re-organise his avionics with an Approach Hub and need to wire the 'autopilot connector' on the Hub to the Century 21. Regards, Aerodon supercub180@gmail.com

I researched the Trio, Trig and GFC500 for installation on a C172. 1) The Trio STC is being developed by a separate entity (to Trio) with a bit of an attitude problem, and I believe a bit of a copyright problem (on the web but not verified by me). The guy keeps whining how busy he is with his day job (Cisco) and his night job (STC Group), and basically told me to F-off when I asked him not to share my email address along with all his customers. He was sending project updates to his entire mailing list without using BCC. If he thinks he can succeed by pissing off the very small number of buyers who are willing to be first - then good luck. I'm glad he did, because the GFC500 is far superior. I looked at the C172 installation at OSH, and did not like the servo with a pushrod onto the cables. Seems goofy to me. I like the Trio autopilot head and features - seems like a great product. 2) The Trig guys were very helpful. I didn't really like the servo on the firewall connected directly to the control column. 3) GFC500 - Garmin have nailed it. The servos with the traditional 'bridle cable' onto control wires seem like the right way to go. I've seen the brackets and drawings fro a C182 and they look right. If you take the G5 out of the pricing, its the same price as the others. But you get tremendous additional value with the G5 - for a start, most Mooney owners can loose the vacuum system if they have an electric HSI already. And then it is going to be forwardly compatible with a second G5 etc. I've just been burned by the Navworx experience. Sitting staring at a $2000 brick right now. I am one to support new innovative companies, but at the end of the day, the smart thing to do is to buy from a manufacturer who can afford to carry a product for as long as Garmin do, have the engineering department to do it well, and something that is likely to add more resale value than say Trio / Trig. Regards, Don

Attached is a screen shot of an EDM900 flush mount. The top one is the standard '8 hole' JPI flush mount. The second two are my design similar to the Garmin G5 mount. A rectangular 0.093 plate is set back with 4 x 3/8" spacers to hold the EDM 'clamping ring'. The 4 holes can go anywhere around the perimeter. Top and bottom, or side by side. If I was cutting the panel at the same time, I would look at where the adjacent instrument screws are and then line them up so it looks neater. Thanks for the idea #jetdriven. Aerodon

Jpi make a flushmount like the Stein G5 mount. It has 8 mounting screws, although only 4 are needed. I can easily make a Garmin G5 plate and spacer style mount, the advantage would be that I can more easily customize the location of 4 mounting screws for aethestics are well as practicality. And by using smaller spacers, you can have the EDM900 protrude 1/8” like the G5, thanks for the idea, Aerodon
