Yep. I used Jimmy's guide from 2021 when I was looking for a J about one year ago. I don't know if he's updated it since then. The market did go up a little from 2021 to 2022, but I think it has mostly gone sideways this year. I liked Jimmy's guide because it helps to keep things in perspective and helps minimize guesswork. It allows you to tell if someone's asking price is unreasonable as a starting point for negotiations if you see something that catches your eye. He discusses the value add/deduct due to hard to quantify things such as recent repairs, upgrades, old avionics, etc. I also used it when pricing the C model when we sold it. Of course, the offer is just step one, but I found that Jimmy's guide got me off on the right foot for both buying and selling a Mooney!

Manufacturer's instructions are to test using a hot oil bath.

I've not heard of these "ceramic waxes". Last weekend we gave our J a belly rub. Ready to wax. Can you suggest a good high quality ceramic wax for a first coat on a clean belly? Is there any downside to use of a ceramic wax- like a long-term residual that is impossible to remove? Thx.

This I understand. Cell reception at my field is not stellar. One day I fired up the engine in front of my hanger, powered up foreflight, and noticed my maps had expired. Connected iPad to AT&T iPhone hotspot, and started updates. SLOW. Then I got the brilliant idea that maybe if I put the phone outside the cabin it would get stronger reception and speed the process. So, I cracked open the door and laid my phone atop the cabin. Probably didn't help, but at least I felt like I was doing all I could. A couple of minutes later, updates completed, and I increased rpms to taxi. THUMP! Something hit my plane!?! Oh crap, I forgot the phone. Shut off engine- exit aircraft- don't see phone anywhere! Look for dents on tail, don't see any (whew). I walked away from the plane, and found my phone about 50 ft aft. Luckily the case on my trusty iPhone 8 took the brunt of the impact with the ground and nothing was broken.

I'm curious, why not just use the wifi hotspot on your phone? Starlink is pricey, isn't it?

I think CHT is typically a good proxy for power output for a cylinder, but it is a better proxy for cylinder pressure. A cylinder that is experiencing pre-ignition has a really high CHT, but is not putting out much power. It does have a very high cylinder pressure. For an appropriately timed engine that is operating normally, I agree with you. But, it isn't an absolute indicator that you can use to compare cylinders because of differences in cooling air flow/etc. The CHT in #2 in my IO-360s is always about 25F cooler than the rest in cruise. But when I lean it out LOP it is neither the first nor the last to reach peak EGT. So, it's in the middle of the pack in terms of fuel flow. If one flight it is significantly different from about 25F different from the other cylinders, I'll suspect something might be wrong.

Gimp.

Yes- helps promote uniform flow

Aha! Finally something on MS that I know about! Your intercooler creates a boatload of turbulence. That turbulence injects a bunch of small scale kinetic (rotational) energy in the flow, which helps promote uniform flow throughout the induction system.

What about instruments with internal lighting? I'm pretty sure the light trays use incandescent bulbs. Would a PWM dimmer work there?

Anyone ever replace those dimmer circuits in a J with a PWM unit?

Update. Just issued at 3:00 CDT... Tuscaloosa National Airport (KTCL) is currently experiencing all inbound flights being held at their origin until Saturday at 03:30PM CDT.

The Tuscaloosa class D airport is just being slammed with exec. jets today with the football game between Texas and Alabama. I flew to Mississippi this morning to get my AI replaced and on my return I was vectored by Birmingham approach before being handed off to Tuscaloosa tower, which doesn't usually happen. Many more arrivals to TCL today than BHM. Looking at flightaware, they are using multiple holds west of TCL to sequence arrivals. They've closed rwy 12-30 and are using it to park jets. They are asking Jets if they can park on the grass. Crazy. Here's the view from taxiway D when I returned.

This thread and your screen name reminded me of this potential answer to your question:

I would expect the English to write better English than that to-be verb salad. It reads as if someone spoke it into a tape recorder.... Just sayin'

I trade a lot of stuff here, eBay, and other sites. When dealing with members of the aviation community I have not yet had a problem (knock on skull). Some folks procrastinate. Then something comes up. Tight money, health issue, you name it. Communication solves that problem to the extent that it avoids anyone getting angry. Some folks procrastinate then guilt sets in... Then one of two things happens- the guilt makes them pay, or they cope with it by pretending it never happened. I'm no psychiatrist, but it happens. Shame doesn't help in this case I'm afraid. That person has already decided to ignore the problem. I'd suggest that persistent reminders is the way to go. The only other alternative involves attorneys and all the invoices they create. Good luck.

Thanks Vic. I did not look under the Route tab. Fred

Checked it yesterday. A couple of months ago I replaced the cap with one of those yellow, gasketed valve stem caps. When I unscrewed that cap yesterday, I think I heard a little "pop" sound. Clue #1. I put a little spit on there and it seemed to bubble once after maybe 30 seconds. So it does seem that the valve might be leaking. However, since the cap I put on it was pressurized, the cap is leaking at a rate slower than the valve at least. Not enough info to confirm/reject tube leak. I'll get a valve tool and tighten it up and go from there.

I experienced EA-100 issues soon after acquiring our J which has an Aspen PFD connected to a KFC-150 a/p. Sometimes I thought the damn a/p was trying to kill me. Speaking of great customer service: I explained my issue here and @Jake@BevanAviation replied that my A&P should check to make sure that the EA-100 was properly grounded. It wasn't. Since being properly grounded, I've had no problems. This did cause me to spend some time looking for a backup EA-100. Used ones are very rare. Most sold are in service it seems.

Configured as you suggested. When uploading a flt plan from iPad to IFD, it does take a few seconds for the "ready to upload" annunciation. After dismissing, the flight plan never arrives. I didn't notice, is there a required LSK press to accept the upload?

Mine too, but the paint on the logo is still crisp and shiny, making it "look" new!

Got this working today. I can now display traffic from the Stratus on the IFD540, which is what I really wanted. One weird thing is, I can download a flight plan from the IDF to Foreflight, but when I upload a flight plan from the iPad to the IFD it doesn't work. When I send the flight plan, a cyan dialog pops up in the lower right-hand side of the IFD saying something like "flight plan ready for upload". I click on that, and viola! Nothing happens. No other warnings or symptoms. Thanks to all for contributing to the discussion!

This is the first time I'm learning about this. Makes sense. Good to know. I'd nominate this piece of information for a MS FAQ. Is it controversial? Seems not.

I ordered a 6" Air Stop tube from AS a few months ago as a precaution because one of the mains is leaking a few psi per week. It's been on back-order every since! Anybody have a good suggestion for another source having them in stock, or is this a widespread problem? I figured it was easier to ask this crowd than spend time bird-dogging. Thx. Fred

Thanks for the data point. My J is 24-1402, and my UL is 880 according to the most recent W&B calcs. Looking at the low end of the distribution that my poll was designed to analyze, there is such a difference. Equipment? They are probably similarly equipped- mine has a KFC150 AP. The manual says that when they painted my J in 2019 they stripped it before painting, so that's not it. I've read that a paint job weighs at least 30 lb so if not stripped it goes on all the rides and eats UL. In an upgrade in March we installed a JPI EDM900 and removed all the legacy gauges and the ADF. It has a single Aspen PDF so it has vacuum pump, and legacy flight instruments required as backups but they don't weigh 10 lbs all together. When I bought it Jimmy G. told me that "in the early 80's J's started getting heavy". I didn't ask him for clarification as in "what changed"? Anybody know? Despite advice I give others, I'm starting to think about tempting fate and weighing it... Somebody STOP ME!
