The guys on Beechtalk are bragging about the hours in different Beechcraft. One guy has all his hours in Beechcraft, 6.5 in Bonanza and the rest in a Baron. And yes, that does mean he got his PPL in a Baron. Aerodon

I need these to replace non working units, need to be nice. Aerodon

Just like the average house, the 'peak demand' is on the decrease. Just replace your landing light with an LED and you've knocked 10-20A of your peak demand. To use the 70A of the plane power you need 2 things: 1) wiring and CB in place to handle 70A 2) the ability to load over 60A. I can do this on my Seneca with dual heated electric props, heated windshield, 2 x 100W landing lights etc. But I have 2 60A alternators so I only need to pay attention if one alternator is out. Now I have 2 LED landing lights, avionics that draw less current so its even less of an issue. What does your electrical load analysis show - I would say its hard to need 60A, never mind 70A in a Mooney? Aerodon

I should know better. I just installed an EDM900 in a C172 and I thought I would give the OEM transducers a try because they seemed to be working OK and I know how to calibrate. The calibration results were very promising (nice curve) so I though everything was OK. But the real world results suck. I now get fuel imbalance warnings (when the fuel totalizer is more than 5G from the fuel quantity) and less than satisfactory Left / Right measurements on the way. They may be true, but I think more likely the transducer is erratic. I'm not going to try again, just going straight for the CiES transducers to get it right this time. Attached is a picture of the panel, the EDM900 works well, even low down near the pilots knee (and near the engine controls). Text is too small to go on RHS. BTW, I have a couple of used FS450 FF and EDM700 systems that I have taken in trade. Or contact me for the best deal on new systems, complete with CNC cut panel. Aerodon supercub180@gmail.com

Are you sure its both? I thought is was $1800 to repair, or $650 if not repaired? I have a new old stock processor for $2,450 for you, trade on your non working unit? Don

Here's a Mooney panel that I have been experimenting with. The off-centre HSI in the standard Mooney layout hurts my OCD, much prefer the aligned look. Allows a bit more space between instruments (required for flush mounting G5 etc.) Also attached is a C172 panel I did recently. I was concerned that the EDM900 would be a bit low, but after flying to KOSH and back, I can assure you it is fine. Next row up would be better. I would not install an EDM900 on the far side, go for an EDM930 then. And I second the opinion that you need to keep a second ILS (or VOR indicator). Need something in case the aspen goes dark. I'd be happy to work with you on developing a layout, and of course supplying an EDM900. Aerodon

The EDM can be setup to measure CDT on pins 5,6 on P1. Its called IAT (Induction Air Temp) and uses a type K thermocouple. Now is the time you should seriously consider an EDM900. Stop throwing large amounts of money at old instrumentation. I'll ask some of my previous EDM900 customers if they have any spare hardware. AeroDon

Gary, I'll take it for my super cub project. PM to follow, Don

Mark, If you have a 'bank' of temperatures that drift in unison, I suspect an instrument problem. Can you send me a data file please? We should try verify the problem, then just send it in for repair. Aerodon supercub180@gmail.com

David, I went back and read the rules about 'stomping' on other peoples listings on Beechtalk. Basically any negative comments on condition or pricing which may negatively impact someone else advert are not allowed in the Classified section. Neither are positive comments allowed. So its not really one sided although it might appear so. But post a thread on one of the other sections its free game. I realize that this is not Beechtalk, so I won't take offence on these comments on Mooneyspace. Neither does Mike by the way, so all is good. Paul, Appreciate the concern for others, but your warning applies to the purchase of pretty decent airworthy airplanes too. Just about any airplane purchase will result in catching up with maintenance, some upgrades, some things that will break just because the plane is pressed back into regular service, etc. Its dead easy to buy a plane for $50k and then need another $30k over the next two years. But this is a different subject, should be in a different forum IMO. Don

Is it just me, or are some of the comments above a bit disrespectful? I thought it was bad taste to criticize asking price? Or make comments about what you think you saw it sell before for? For the right person, this is a deal. There are guys out there looking for projects, others looking for a wing, someone looking for a cowl etc. If its not for you, or you think it will cost too much to restore, just keep quiet and move on. I bought a C150 'project' with a new taildragger kit in far 'worse' condition - look at it now. It made as much financial sense as buying a $5 coffee, but its been a lot of fun. Aerodon

No disrespect, but have you tried it? You are correct, there's less than $100 worth of 2024-T3 in a panel, its all in the CAD and machine time. And then some more for painting and labelling. I've got about 40-50 hours into my Mooney panel drawing alone, and thats using a good library of 'shapes' for things like HSI's, altimeters etc. Then at least 5 trial runs on a CNC machine before I had a panel that met my standards. Iterations are required to catch errors, make major layout changes when things don't look right, make minor changes to get instruments, switches and screws to fit. And of course check that it fits into the airplane without interference. Add in finding a 120t press to bend the bottom edge with a 1/2" radius. Then finding a good paint and primer system. I haven't even got to engraving the lables yet, but the closer you get to completion, the more time and cost you have in the panel, and good luck in getting the local engraving shop to get it right the first time. Aerodon

don't you need to keep your VSI? Don

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
