I removed these from my 1986 252 and are available individually or together. With tray and connectors. Aerodon

I think the EDM900 along with a GI-275 on the RHS of the G3X is functionally better and looks really good. Attached is a panel for a 252 with a G500. Aerodon Mooney_M20K_N252RM_V6_600.pdf

I have this nice 2019 EDM830 display that I can provide with a good used harness and probes for a 4 or 6 cylinder aircraft. 4 CHT/EGT, OAT, Oil T, MP, RPM & FF transducers. P1,2,3,4 harnesses. Aerodon

Max, I've installed several EDM900's and figure about 30-50 hours. Sometimes it can take a lot of time cleaning up previous installations removing OEWM transducers, getting new hoses for pressure instruments etc. And depends what else is happening, to make it easier or more difficult. If the cowls are off and the instrument panel side does not require a lot of modification it makes it quicker. There are some things I like about a GI-275, wider selection of transducers, ability to set and change your own alarm limits. Smaller footprint also helps but makes it harder to see numbers. I think a GI-275 for flight instruments is a dealer install, I think the engine or MFD is an IA install? Don

Look at the warbirds over wanaka yak 3 crash. The pilot specifically asked if the grass runway was in use at the briefing and was told that it was. He was uninsured and successfully sued the organizers and the guys responsible for placing the cherry picker on the runway. Read about the P59 and B17 crashing Texas, there was no real horizontal or vertical separation plan discussed at the briefing, and look at the end result. The thing about liability is you have to prove the other party was liable. In this case the organizers came up with a rule, and the pilot ignored it. Not to say a jury wouldn't somehow find the organizer partially liable. And then the waivers. The local ski hill has several 'issues' a year (I won't call them accidents), some of them escalate to settlements and some eventually escalate to lawsuits and damages awarded. Aerodon

Twice other spacers have been scammed by someone masquerading as me. Once for an item I was not even selling. The private messaging system is fairly secure, but at some point a seller has to provide a phone number, email address or real address for payment. I think what happens is the scammer sees someone posting interest in an article and then jumps on your user name to provide an email to take the correspondence offline. Please use caution and do some cross checking before sending money. Aerodon Donald Hague

I've been going through my stock on the shelf and can put together a nice system for a 4 cylinder system: 1) EDM700 with data and fuel flow, new display. Comes with factory return to service documentation. 2) Good used transducers - EGT, CHT, OAT, Oil T, FF - all the data you need to record for engine trouble shooting and analysis 3) Good used harnesses - P1 (Power, data, OAT, Oil T), P2 (CHT/EGT), P4 (fuel flow, GPS, FF switch) 4) Pilot Guide I'll get this ready for installation, making sure you have all the harnesses, sleeves, terminals etc. And I will make sure all the wiring harnesses are long enough and good enough to reuse. And I'll warranty all parts for 3 months. Other systems available - EDM800, 6 cylinder, EDM830 etc all the way through to EDM930. Aerodon

My vote would be for a GNX375 - combined GPS transponder. Start with a low cost insta and a standalone, save up for G5's or GI275 later? Remove and sell the DME and KT76A.

Yeah, the FBI C182's had 2 KMA24H's with intercoms, always confused the heck out of me. I used to get get one radio and the intercom working then don't touch anything. Eventually we did a panel makeover and got rid of them.

I have too many audio panels on the shelf. The PMA450,8000B and SL15 are new old stock, complete with install kits. The PMA8000B and PMA450 are forward compatible with the PMA450C and various Garmin audio panels. The SL15 is still a very nice audio panel and is a nice way of adding a stereo audio panel with intercom to an existing KMA24 audio panel. I have a guy that can make a harness for the intercom side. The PMA7000 is in excellent condition, has the DRAWS (digital recorded audio warning system?) that can give voice annunciations like 'check engine' 'check vacuum' etc. This was in my Mooney, kinda neat, but will take some figuring out how to connect. Can sell with or without install kits, so priced at US$1000 through US$1600. I also have Approach Systems hub and cables to go with these. Send me a PM and let me know which you prefer. Aerodon

I've seen them split.

I recently sold some pedal extensions and some other loser tried to get payment directed to him. And a month ago I sold some brake masters and the buyer got scammed out of a deposit. There are bad guys amongst us, sometimes its easy to spot, sometimes not. Don

both sets of 1.5" extensions sold, thanks.

Me too, if it wasn't for all the holes and permanent rivets I used I'd consider upgrading. You did nut plates, so go for it? Aerodon

post a picture of your speed brake switch. I have drawings showing the 2 or 3 different types. Aerodon

I have 2 sets of 1.5" extensions, one set is sold.

Here's a set of OEM 1.5" pedal extensions for $120. If you want a set of 3" pedal extensions and understand the requirements for an owner produced part, I can make up a set of 3" extensions for you. Aerodon

There are several connectors in the circuit from the avionics relay to the ground. If any one of them were open or intermittent then the switch would not ground and the avionics would stay on. Some switches have 2 poles, only one in use. Swap the ires over to the other side? But if there is a fault in the small control relay, this could provide an alternate path to ground to hold the avionics relay in the on position. And the avionics relay could be sticking. Aerodon

You can calibrate the JPI OAT in the setup menu. Aerodon

Are you familiar with the Charlie Weights on a 231/252? Is there a shelf and holes pre-drilled into the aft bulkhead an a M20J? Much as I don't like adding useless weight, this is a very effective way of fine tuning your CG. And for the people contemplating upgrades - consider remote boxes for transponder, traffic, stormscope etc., especially if you already have the avionics shelf in the back. Not only does it help your CG, I think it makes the overall installation easier because things are not as cramped behind the panel. Aerodon

In my M20K there are 4 son alerts right next to the speaker. Stall, Gear, Altitude Preselect Alert, AP Disconnect.

Hi Lee, Good first try and I can see you put a lot of effort into it. The overall layout hurts my eyes a bit, a bit of a random layout. My guess is you are two or three trial versions away from a final cut. I am on Rev_10 for M20J's and K's, and each one is a little better. Mooney used 0.100" and had very little material between th instruments. Tightest layout out of all the manufacturers and thickest panel. And most instruments have an 0.090 bezel anyway. 2024-T3 works well. And it looks like you are not doing the 1/2" radius at the bottom? Aerodon

I can't ever remember the alternator output pegged at 60A, never mind 70. Especially with LED instead of halogen LL's. There might be a bump when selecting gear up or down, or after starting. So really no benefit or problem installing a 70A alternator, and unless you reach 60A you are not going to trip the breaker. And breakers are notoriously inaccurate anyway. And its not like you are changing from a 40A to 70A alternator - I would look at the aircraft wire sizing chart, you may well have a big enough wire for a 70A alternator already, then go ahead and change the breaker?
