I have an intercom there in my J. There's quite a bit of space. You can access it by removing the side panel in the pilot footwell. It's only a couple screws to remove the side panel.

I can’t tell from your description exactly what’s interfering so I’ll throw this out there. There’s a small bracket that should have been replaced when your landing gear was converted to the new style of shock discs but I’m not sure this always happens and I think if there’s enough play in older gear it might not cause a problem. It’s described in Mooney service bulletin M20-139 https://www.mooney.com/wp-content/uploads/2020/12/SBM20-139A.pdf. On page 4 item 8 describes the bracket that needs to be replaced. On page 6 under “Main Gear Parts to Install” item 6 is a note that the gear won’t retract unless this bracket is replaced. I’m not saying this is necessarily your problem but it seems worth confirming that you have the new bracket.

When comparing the older models to the J everyone focuses on the speed mods and purchase cost but nobody talks about the single greatest design improvement of the J. It doesn't use one of those accordion air-intake boots made of unobtanium.

When you say the "inside diameter of the nose gear" I'm guessing you're asking about the tube where you insert the towbar. If so, then what you're looking for is here:

Have you turned it on and left it to warm up for a while? Since I don't use mine very often it usually takes a while for the display to warm up. If it's been sitting for a long time it could take a while before you can see anything on the display.

You might be thinking about a different radio. The KNS80 is capable of receiving localizer and glideslope so it works well for flying an ILS or localizer approach. It has some interesting features for en route navigation but even if you never learn how to use those functions it is a perfectly good backup nav radio that includes DME.

On the Aero Classics website it says that part number is for a piper. They have a different part number for the M20J.

The SB I linked references the AD that makes it mandatory (AD 97-26-08 just below the subject line in the SB). Here's the AD. https://drs.faa.gov/browse/excelExternalWindow/3663F2D3749FE48286256A8F006C5ED6.0001

Indiana has recognized DST since 2006. Aside from a few counties in the northwest and southwest corners of the state, it is always aligned with eastern time.

According to their website they aren't currently offering tours of the restoration hangar. https://www.nationalmuseum.af.mil/Visit/Groups-and-Tours/ Kings Island is in Mason which is part of the Cincinnati area. It's about 40 miles from the Air Force museum.

The presidential collection has been moved into the main museum.

There's an M20C for sale here on Mooneyspace with an ad that says "No damage history" yet Aviationdb.com says there was a gear collapse. Is that damage history?

Where did you find the new ones?

I don't think they were shipping many 2008 Ovations with rotating beacons.

The 1977 Js have the old crank style mechanism.

@steingar is quite the origami artist and has several books on origami airplanes.

I owned a (converted) M20D for 9 years and now I've owned my M20J for the same length of time. The J is slightly more pitch stable than the D but I never really found the D to be unstable. It's just a difference I noticed when I upgraded. The difference in rear seat leg room is meaningful. I'm 6'5" and there was essentially no room behind me in the D. My wife (5'4") rides comfortably behind me in the J. The rear seat of the D was ok when the kids were in little and in car seats but they quickly ran out of room as they grew. The rear bench seats in the two planes are also slightly different. The angle between the seat and the seatback changed. In the D the angle was more acute and less comfortable. I no longer get complaints about the comfort of the back seat.

The SDS I found online says Corrosion X is >90% petroleum distillate so it's hydrocarbons like fuel or oil which shouldn't affect sealant. The rest of it is some proprietary amine in some proprietary percentage. I wouldn't expect that to have much effect on sealant but it's hard to say for sure.

Ethylene is a gas and isopropyl is a hydrocarbon substructure. Are you referring to ethylene glycol and isopropyl alcohol? Methyl is also a hydrocarbon substructure and wouldn't have much affect on something designed to resist fuel or oil. Acetone and MEK are structurally similar ketones. That's likely what's impacting their ability to soften the sealant.

I don't have any personal experience with One Wheel devices but if you're considering getting one it seems relevant to know that the CPSC has issued a safety warning about them. The company has not agreed to a recall. https://www.cpsc.gov/Newsroom/News-Releases/2023/CPSC-Warns-Consumers-to-Stop-Using-Onewheel-Self-Balancing-Electric-Skateboards-Due-to-Ejection-Hazard-At-Least-Four-Deaths-and-Multiple-Injuries-Reported

Two points: 1) Atmospheric gas is normally represented in ppmv (parts per million volume) not mass even though they write it as just ppm. Details here: https://climate.nasa.gov/news/2915/the-atmosphere-getting-a-handle-on-carbon-dioxide/ 2) I think your calculation is off by an order of magnitude. 23 trillion is 0.4% of 5.5 quadrillion not 0.04%.

Installation instructions are here: http://sarasotaavionics.com/manuals/appareo/Stratus-Power-Installation.pdf It specifies a CB but no fuse. It looks like the power can easily be disconnected from the back and you could use a multimeter to determine if power is getting to the unit.

When it says something like 25-0640 THRU 25-TBA it means that all s/n above 25-0640 are included. So it looks like VI and VII are both valid for your plane for part #3.
