Putting this out now in case there is anyone searching for any of this stuff. This is a 1989 M20M.

My panel makeover starts Monday the 9th of June and every radio, instrument, and gauge in the current panel, with the exception of the GTX 345 and the WX-950, will be available. I'll wait to see what condition they come out in and what sensors will be included before pricing anything, but everything works. 

The electric standby vacuum will also be coming out if anyone needs one of those. I'm keeping the primary vacuum system for my speed brakes.

I haven't decided about switches yet but the breaker switches may also come out. Maybe.

I'll update this as work progresses and I have the parts in hand and detailed pictures to post.

Cheers,
Rick

I’ll take any of the primary instruments you don’t sell for my paperweight collection, although I’ve been surprised at how light some of the instruments actually are.

It’s like when the world switched from mechanical watches to digital. The digital watches out performed the mechanical watches in every respect. But the mechanical watches were works of art. The digital watches were a tiny microcontroller and some cheap software. The mechanical watches were heirlooms, the digital watches were just throwaway little trinkets. They are getting us to the point where our avionics are just throwaway trinkets that you replace every few years.

I already have a plan for the items that aren’t useful to anyone. I’m building a “Nostalgia Wall” into the improvements I’m putting in my hangar. Right next to the “I Love Me” wall of all of my, well, personal nostalgia. But of course there’s also a bar on THAT wall.

Rick

Can you keep the electric standby for the speed brakes and get rid of the engine vacuum pump? Getting rid of the engine pump makes oil changes and a lot of other things so much easier on this engine.

I thought about that and opted for getting rid of the heavier system. The electric vacuum system weighs 12 pounds in total, from what I’ve been able to figure. But, that 12 pounds is on the right end of the airplane and the the things you pointed out are definitely benefits to be considered.

There’s also the question of what it would take to wire the speed brake switch to the vacuum system, and how to do that within the rules. It’s possible this has been done before. Do you have anywhere you can point me for more info? Maybe someone with first hand knowledge?

Now that I think about it, when I was getting bids the folks a Sarasota Avionics mentioned the same thing but they didn’t know how to make it work. But that doesn’t mean there isn’t a way.

Rick

The Precise STC doesn’t allow for it to run the Speed brakes off the electric standby vacuum- it’s got to be driven off the engines vacuum pump.

Even though we all know it’s makes no difference.

Ok, here’s a question that may show ignorance on my part. My airplane came from the factory with the speed brakes installed as standard equipment. Is the STC relevant in that case? I’m guessing yes, but hoping maybe not.

I really doesn't matter. They were never certified/approved to run off the electric standby pump only.

Why won't the electric standby pump do the job?  It looks identical to the engine-driven pump.

We all know it will do the job, as I already mentioned above. But it wasn't approved that way.

A little bit like your earlier question upon learning LASAR has lost their PMA status to repair/make gear trusses and you asked do we know the correct heat treatment method. The answer to that is irrelevant, the correct practical question is there anyone else approved to repair a Mooney truss?  It could really only be a repair station (or manufacturer)  that has an approved documented process for repairing them in order to provide a return to service documentation.

My brain always goes to "how can it be fixed" first.  But I see your point.  I guess we all need to prepare for an ever-accelerating flood of scrapped Mooneys.  At least there will be some of those parts returned to service on an ever-shrinking number of airworthy airplanes.

Well without an accelerating flood of scrapped mooney’s there are plenty of salvaged trusses available - one needs to only look on ebay.

Rick, let me know how the shop handles the vacuum pump installation with only the speed brakes.  When the brakes are not in operation, the entire flow is though the regulator and the 'garter filter' around it.  Can it handle full flow?  Or should one leave the other filter installed, with a restrictor valve installed to simulate some other r vacuum instruments installed.

Will do. I recall this coming up in a past thread so someone has done it already.

I run that way now and have been for years - not a problem. Many Mooney's are. But someday there is always the option to upgrade the speed brakes to electric. I am putting that off as long as possible.

Excellent, thanks Paul. My plan is the same.

Yea, me too Anthony! For the inquiring minds, here's the going-in plan. Subject to modification as my installer and I conspire on "improvements".Image5-4-23at2_25PM.jpg.952a6eaa8e6d85ae045dfc3e6c155629.jpg

UPDATE 6/5/23 - Final(?) layout plan

Looks beautiful just the way it is! But since everyone else is going to be giving you suggestions to tweak it a little - here's my 2 cents.

The focal point of your left panel is the G3X - I would center your TKS Panel below the G3X, rather than over your switches,  just for aesthetics. Also on a Bravo panel I did, I moved the Mooney annunciator over to the left panel at the top centered over 3 Aspens I had (G3X in your case, which would have to come down just a little, but you have the tallest of all Mooney panels in an early M20M). Not only did it free up precious space in the center stack, but if there's an annunciation it's nice to have it right in the center of your field of view. That space savings, plus if you went remote on your audio panel and/or transponder,  allow a GTN750xi in the center stack. Even if the transponder had to go to the right panel you can always control it from the GTN750Xi. It is so fun trying to blow through someone's panel budget . . lol. But one thing you don't want do on a major project like this is to look back and say "why didn't didn't I  . . . "

Also since you are going all-Garmin I would spend a small amount extra and put the dedicated Smart-Glide switch on the panel.

@PT20J mentioned in a recent post that now with a recent software update that the GI275 does everything that the G5 did in a G3X installation. If that's the case, everything I've seen about the GI-275 would make the difference in price worth it to me (better resolution, SVT, fully TSO'd).

Not only did it free up precious space in the center stack, but if there's an annunciation it's nice to have it right in the center of your field of view.

I would not center the TKS over the yoke as it makes it awkward to interact with, think how you will both fly the plane, manipulating the yoke and at the same time reaching over it to work the panel buttons and switches.

I would leave the G3X up high as possible.

Only things you rarely interact with should be on the left/centered above the yoke, or on far right radio stack. Remember you may not be able to remove your left hand from the yoke.

If you must put annunciator below the G3X. Most of the annunciations are probably handled by EIS (fuel related, voltage) or no longer applicable (vacuum).

Id figure out with the screen in split screen mode, where the PFD will be centered and center it on the yoke. I can’t imagine you’ll use full screen mode very often.

Edit: I’d also install a panel mount compass and remove the factory hanging compass.
