Thanks Osuav8ter, payment made via your website. I'm in LA (from Australia) in 7 days and will get it sent to the crew hotel. The bloody thing worked when polarity was corrected. Then most worked. Now none work I'm told. Cheers.

So we have 12 years and 19 years between incidents (4 total) and how many gear operations in the entire fleet did we have in that time? Not exactly a risky issue in the big picture. IF I had an electric suck'm up I don't think I'd be too worried. A lot of other things happen more often than that. Can we say "stall, spin" or "forgot the gear" ? Lots more vulnerability there than a simple spring - fleet wide. Would I change the spring? Probably if it hadn't been changed in 30 or 40 years, just to be proactive but I certainly wouldn't lose sleep over it. Considering the possibility of maintenance induced failure and the complexity of the replacement I'd sure be going half way across the country to find a shop that has done a bunch of them. Might be a good excuse to install new 40:1 gears at the same time.

That is very true, people and government seem alarmed these days with pollution, however, there is literally nothing new under the sun ! I recall reading the most polluted day in history of Paris was in 1900, the solution was switching to ICE cars (politician are exactly the same: making laws on the fly, showing they are doing something, taxes and bans here and there…). https://earth.org/data_visualization/air-pollution-in-paris/ Around the year 1900, Parisians knew they had a serious pollution problem. No, not smog and particulate matter, they said, but the dung from over 80,000 horses carrying people and loads around the city everyday. Officials decided to test moving horse-drawn vehicles to the verge of the Champs-Elysees causeway, while motorized vehicles would be given the center. The contrast between the manure-laden and rubber-smoothed aisles left people convinced (translated from a French article in the “Figaro”): “It is easy to see that, from a hygienic standpoint, automobiles whose exhaust is rapidly absorbed by the air, are preferable to equestrian carriages.” https://www.lefigaro.fr/histoire/archives/2016/07/01/26010-20160701ARTFIG00300-en-1900-le-pic-de-pollution-a-paris-est-du-aux-moteurs-a-crottin.php#:~:text=En 1900%2C on compte près,%2C de «parfums pernicieux».

Yeah, the novus works reasonably well too but I need to find some kind of an orbital polisher to get inside the windscreen, especially low, close to the glare shield. It’s really hard to put any oomf into it by hand there.

Am i the only on that does 2350 or 2300 lol

You know the kits that are for polishing out your headlights will do wonders for your windshield.

I was there on 4th of July. The airport was good. No problem.

I am flying to Hot Springs (KHOT) on Monday. I see that runway 05/23 is closed. Has anyone flown there recently? Just curious as I have never landed on 13/31, and it doesn’t have an instrument approach.

1894 was peak horse shit in NYC. https://en.wikipedia.org/wiki/Great_horse_manure_crisis_of_1894

Ultimately, everything comes down to economics. Is there a market and can i make a profit

Actually fuel was the reason for horses going away. To create fuel for horses hay and silage had to be hauled into the city to the livery stables. Livery stables required large plots of land which as cities grew was too expensive and resulted in "high ramp fees" for horses and we have not even talked about water troughs. Many cities outlawed livery stables within the municipal confines because of health and economic reasons, just like leaded fuel now.

Well in all honesty there is a mandatory biannual IRAN procedure for the contents of the brain..

Yet another good reason to be a paid supporter . . lol

Bottle with regulator , mask, two cannulas, bag and book the aerox 24cf bottle is 400 by itself $600 at KHRF

Sorry to revive this, but I’m going to put together the supplies to attempt some work on my windshield. You can’t catch a finger nail in any of the scratches but it’s been marked up pretty good both on the inside and the outside. Especially where the instrument panel cover has been taken in and out. I have Novus 1, 2 and 3 and those don’t seem too aggressive. Does anyone have a good recommendation for an angle polisher with an adjustable head? And what kind of foam cushion should I use on it?

Ex-machinist and shipyard guy here. Stainless fasteners just sorta stink to begin with, IMO. The galling or "snowballing" is a real problem. SS and aluminum are far apart on the galvanic scale which accelerates corrosion. We used to use a product called "TefGel" when we couldn't isolate Carbon from SS very well. Typically, though, we would bond a glass sleeve into the carbon fiber and use a glass washer, to keep the direct Carbon to SS contact low. Of course with carbon fiber, Titanium just happens to be close on the galvanic scale. A hassle to machine/fabricate and super expensive! At any rate, that galvanic scale pictured is the gospel. If you have dissimilar materials, you want them to be next to eachother on that scale. The further apart they are, the more they will corrode.

While running your TIT at 1644 is under the POH max, running that TIT temperature you will go through cylinders and exhaust systems on the Bravo engine. Normally we all think of the POH as the final authority but if you take into account all of the experience that Bravo owners on this forum have, in 36 years now since the M20M was introduced, the recommended setting for longevity on this engine is a max combined number of 53 (MP + RPM; Example 29MP + 2400RPM). Also keeping the TIT below 1600 will prolong the exhaust valves, exhaust system and TIT probes. The POH was never revised from the original and it says 1750 max, but that's when in the early life of the M20M people were going through a set of cylinders every 200-300 hours. The early M20M owners fought the battle and eventually Lycoming devleoped the wet-head (Bravo) engine, which helped. However still even with the Bravo (wet-head) engine you'll still never hit TBO if you run POH numbers. The other big thing with this engine is that the TIT probes really only last 200-300 hours - less if you run it hotter than 1600. When the probes fail the TIT reads low, compounding the problems. As an example someone runs it at 1650 indicated when in fact the TIT is really 1750 since the probe is bad. This will mean turbo overhaul, exhaust overhaul and cylinder replacements. Looking over the logs and seeing when the probe was last replaced is very important. I've had three M20Ms and there are a lot of other people on here with a lot of M20M time as well and that's what we have learned so far.

Yeah! Especially because it happened last Friday and Monday I had a 750nm work trip planned. Thankfully it was nothing serious. By the way, just flew my longest flight so far... 6.1 hours block time (5.8 air time) on the Mooney. What an amazing plane!

Interesting....four gear-ups due to no-back spring failure in 4 decades. How many gear ups in those 4 decades due to no brain?

Yes, government mandated innovation is the key to success…thank God they made horses illegal in the early 1900s or the automobile would’ve never been invented and city streets would still be full of horseshit.

Here are three systems! The big bulb came out of my J, working when removed and never any issue except me catching the power cable in the cowl and tearing the insulation. The blue one still works, but the original black does not. The other systems are the smaller bulbs, likely for a K or other dual light system with taxi and landing lights. Same 50W XV1A-50 ballast/controller for all 3. I bought this for spares and TBD future use but went with a modern LED instead. These work with 12 or 24v airplanes, and can interface directly to the original switch wires. $150 for each system, or $350 for all 3! Sent from my motorola edge plus 2023 using Tapatalk

No, it is NOT an engineering problem! The SpaceX/Musk analogy is FALSE! He absolutely saw a HUGE market (launching other people/countries' satellites) for ENORMOUS amounts of money. It was absolutely worth the STAGGERING amount of development costs because the payback has been AMAZING. No NEW economics; just the same old ones: see an emerging market, use your capital and expertise to, well, capitalize on it! There is NO such payback waiting for the development of a clean sheet GA piston engine. It is about as much of an antithesis to SpaceX as I can imagine. If SpaceX was publicly traded, I'd invest in a heartbeat. IMHO, only a fool would invest in a 'new' GA piston engine project And, hey, I understand the emotional nature of this...I, too, am royally pissed off! For me it's this 'no lead' mandate being forced down our throats!

I was told it was a “streamlined” brick.

This is what I have for settings. I usually cruise at 30” give or take. I keep my cylinder head temp around 340 and burn around 17 gph. 190kts is pretty common up in the teens TAS. Engine has 300 hours and plane has 1150 TT

It really appears that mooney is transferring what they can to LASAR and shutting down. Now could this be to shed to existing debt? Probably. Could it be to shed China out that still owns 20%? Probably. Could they then turn LASAR into Mooney? Possibly. Frankly, as long as someone finds an actual businessman that knows aviation business to take of "mooney " stuff. But really mooney is no longer viable.
