Oxygen topics must be in the air! Dad jokes aside, does anyone have a recommendation on where to purchase just the Scott fitting that will fit a constant flow tube (like an Aerox or MountainHigh constant flow)? Aircraft Spruce has the "Retrofit kit plus Scott type fitting" (#13-18992 here https://www.aircraftspruce.com/catalog/pspages/retrofit.php) but I really only need the fitting itself and don't want to drop $105 on a 1 inch piece of brass, though 0.1 AMU to ensure oxygen flows is probably fine if it comes down to it (Other relevant thread on this topic pasted below for anyone that ends up here because of a search for "oxygen" or "Scott fitting".)

One word of caution on yoke mounts and autopilots. It is purely a theory but I was having fits with my A/P disengaging in relatively light turbulence when I had my iPad mounted to the yoke (no it wasn't hitting the disconnect button ). I removed it and have since not had the issue. Again, theory but I wonder if the additional weight on the yoke puts additional burden on the trim servo. B

Roger that. I'm looking at ~22.5k quote all-in for the GFC500, G5, and GAD (install estimated at ~10k), which is tough to stomach given my KFC was doing great until the computer fried.

Has anyone on this thread installed the GFC500 with a G500 (not Txi--the original G500)? It's frustrating but it seems like even with the G500 you still need to install the G5 backups and associated GAD29 interface.

Appreciate the input. Have sent a note to a few recommended avionics shops in the area in addition to Weber. Will report back when we figure out the problem and what we do/did about it!

Acknowledging that there are a plethora of KFC150 commentaries on MS, coming back to the well for more. Our panel: G500 with GTN 750, GNS 430, KFC 150, KAS 297B (and then a bunch of Garmin gear for XM, traffic, etc but not really pertinent). Our problem: We were in the decent yesterday (around 2200 feet) when the KFC 150 failed (basically powered down). It did not pop a circuit breaker--just failed/turned off. The KAS 297B altitude preselect was still 'on' and indicating it was receiving but had 4 horizontal bars across and would not allow for any inputs/would no display an altitude. The electric trim was still functional. After landing, the electric trim rocker switch also failed (i.e. it would click itself off after being turned on but again, no circuit breakers would pop). It's worth noting that the panel mounted thermometer was about as hot as I've seen it with the temp just below the dash/above the annunciator panel at 115 degrees). Diagnosis: We went back today following some calls and were able to isolate the problem to the KFC 150. The electric trim switch would stay 'on' (and requires the A/P circuit breaker to be in), the altitude preselect will not work (though it powers on), and the KFC 150 will just not power on (no lights no nothing). Question: Has anyone else had their KFC system fail like this (it feels to me like a failure that will require some level of overhaul...) and what was the price to fix? At this point seeing some of the other horror stories pouring 5-10k into a KFC repair when a GFC 500/G5 all in is 19k makes me wonder. And I know executive autopilots on the WC is well liked--any suggestions closer to home in Northern Virginia? Thanks, as always!

I would recommend prior to pre-buy you have a Mooney professional review the logs. It will make the prebuy much more targeted and give you a relatively cheap sniff check of the plane before you go to the trouble of a deposit/P&S/PPI/escrow/etc. I used JD and Laura out of SW TX aviation and couldn't have been happier. For 0.2 AMU, you can have a detailed write up of every inspection, what's out of date, what's coming up, etc. They will point out things like an O2 bottle that needs replacing in 8 months (which wouldn't be obvious necessarily but can cost ~2.5k when you account for everything), or that the fuel tanks have never been treated (which means that you almost certainly will be the one to treat/seal them if you own the thing longer than a few years), or that there was a tiny print entry for an AD compliance with sudden prop stoppage (even though the seller didn't note any prop strike/stoppage as part of the posting). The specific cautions are long to list and highly dependent on the systems installed. But send the logs/review them yourself and things will start to emerge. There are also a few threads here on the topic of PPI cautions. One that perhaps is politically incorrect to note is the previous owner. Even when dealing with a broker, I insist on speaking to the owner to understand what kind of owner/operator they were/are (and owners before the current one if possible). Some owners treat their Bravos like a piece of old lawn equipment... others respect them and treat them like the extremely capable (but also temperamental) machine they are. You can tell within a couple minutes of speaking to someone what kind of owner they are....

I was in the Bravo market for several months. I can tell you that although some languish, the 'good' ones are scooped up in <1 week. To your point, there are a lot of red/yellow flags to look for when diligencing a Bravo.. many of the ones that seem to sit (probably/possibly) have some of those flags when you get into the logs.

Relighting this thread, does anyone happen to have Bravo performance numbers that would be readily importable to Garmin Pilot? If you only have for Foreflight, I'm happy to take that file, convert to GP, and then share back out to Garmin users! One thing's for sure, I won't be using the POH numbers as I'd like my engine to last longer than 300 hours :D.

Thank you and I have been using the search feature heavily :0. Is it 'safe' to tow/winch the plane from the aft tie down point? I actually used to do this with my amphib because it had no other tow points, so have all the gear to do it!

Hi all, A few questions that I have following some initial flights... 1. Oil: Do you generally use Camguard/oil additive? I've never used it in the past (on an IO-360 that ran Shell 15-50W and already had the additive included) but given the Phillips 66 X/C 20W50 doesn't have that additive (I don't think), I wanted to see if yall are using it. 2. TKS: I have heard a lot about the importance of pre-flighting the TKS system and 'priming' it. Is there more to this than what is stipulated in the operating manual (i.e. more than just turning the system on as part of pre-flight and ensuring fluid is flowing where it should/shouldn't? Also, is there a good way to tell the TKS fluid quantity as you're filling the system? I suppose you could turn master on and fill the system and look to see the gallons on the panel display but wondering if there's another method? 3. Preferred motorized tow bar? I have a winch in that used on my old amphib but don't like the idea of yanking the Mooney from the tail tie down so we're in the market for a tow bar (push bar?)?

Closing the loop on this topic, we are now the proud owners of N9153Z. The experience with N611DG and Maxwell was sort of like finishing school for the pre-buy process/inspection of 53Z. We flew it back to its new 'home' in DC from North Dakota yesterday. There are a few squawks to resolve following the ~12 hrs of flight in the last couple days as you'd expect but I'll start separate threads/see what else is already documented. Thanks for all the input and messages the last month! As an aside, the team at Oasis Aero out of Willmar, MN was great to work with. We got a thorough honest inspection in about 5 hours on Friday in time to close before the weekend. PM if you ever need any details/guidance as I've now gone through a few 'false starts' before this one worked out! (I tried to recreate @DVA and @LANCECASPER's photos. Here's the post from a few years back on 53Z: B

Along the same lines, if you gut the attitude indicator, DG/HSI, and vacuum system (primary and secondary) to replace them with a single G5 backup instrument... How much weight savings are we talkin'?

Thanks gents. For now, I just need to get the factory CHT 'steam' gauge into working order (as part of a purchase) but I think the 900 (although perhaps the G5 so we can gut the vacuum system will take priority..) is on our 2-year roadmap. @Skates97 let us know how the install goes!

Any perspectives on the cost to upgrade from the JPI-830 to the JPI-900? I'm curious why it seems the 830 is more ubiquitous than the 900 given the 900 frees up all the original engine gauge(s) space? Is the 900 much more expensive, prone to fail, just didn't come out until after the 830, etc?
