The cylinder heads do run cooler, often much cooler, but it’s largely due to the lower power output as cyl head temp follows power output pretty closely. ‘LOP does work, however it’s for low power, don’t believe that it’s not, no gasoline piston engine that I’m aware of doesn’t go into “power enrichment” when run at high power, even the newer computerized fuel injected outboards, that excess fuel does help cool, it’s not needed to make more power, it’s needed to keep the temps in control. So I’m thinking the marketing dept made that decision, because run one LOP and it’s not the “Hot Rod” it is ROP. Lycoming doesn’t recommend LOP, in my opinion that’s not because it doesn’t work, but because the power loss in a Lycoming is quite large, that may be due to lower swirl in a Lycoming combustion chamber. Swirl is something that’s pretty new, it wasn’t thought about back in the day when Hemi combustion chambers were the hot ticket. One day maybe airplanes will have Pentroof combustion chambers and four valve heads, but I’m not holding my breath. So if LOP is used as an economy measure, which also means lower power and slower speed, it won’t do any harm, and in fact I believe a solid argument could be made that an engine operated that way will outlive one run at high power, rich and higher cyl head temps, of course that guy is going much faster and a counter argument could be made he’s running his motor for less hours I guess. ‘It’s when people try to recover the power lost from running LOP that bad things can happen, face it, yes it can be done with modern computer controlled engines with knock sensors in the manifold and the ability to independently adjust each fuel injector and vary ignition timing independently for each cylinder, but for our maybe 1940’s engines? Maybe not. We think with engine monitors we have all the data to do it, but compared to a microprocessor hooked to a knock sensor and an O2 sensor in the exhaust and learning ability to build injection and timing “maps”, we just can’t possibly run at the edge like those motors can.

Were it not available to any and all, I’d agree, but the FAA has determined for whatever reason that aircraft owners are allowed zero privacy, registration is openly available as well as our every flight, because your not allowed to turn off your ADSB. If it bothers you, and I think it should, make your complaints to those that might could make a change, elected officials. AOPA etc.

Wow, did you read that? I’m going out in a limb and going to say that the issue was foreign nationals drug trafficking and other illegal activities, not LLC’s

cut and pasted from here https://www.49dollarmontanaregisteredagent.com/vehicle-llc Maybe they are lying, and I’m certain a court order gets all your info, but John Q. public isn’t. ‘They do aircraft too, aircraft are less expensive and easier as there is no license tag, title etc. Benefits of Using a Montana LLC to Own an RV: Remain anonymous.

By not owning an RV personally, you can keep your personal name from being associated with assets, and you will reduce the amount of solicitations you would get otherwise.

I’ll run LOP myself often but I do so only at lower power. What bothers me is when I read that you can run high power LOP. You can go fast, or you can run LOP but you can’t go fast, LOP. Much of the fuel saving from running LOP is actually from slowing down, but who cares why, so long as you burn less to cover the same distance. Detonation destroys engines, so avoid operations that may allow it, I won’t bump my timing up either, although I’m sure you can get away with it, it reduces the margin. Lycoming is a different combustion chamber design than Continental, and I suspect just from listening to some of the Continental’s idle they have a more radical a profile too. The 210’s 520 loped like a dragster. I used to love to hear it idle. ‘Point is I think Continental engines work better LOP than Lycoming, or at least a 520 works better than a 540, I can’t speak for others, but my 360 without Gami’s runs smoother leaner than my 540 did, maybe it was because the 540 was a parallel valve motor?

This does a decent job of explaining detonation, but it should be noted that detonation can occur at pretty much anytime there is fuel, air and compression, to include even after the spark plug has fired, however that detonation is not usually as destructive as often the piston is on its way down and combustion chamber volume is increasing. It’s most destructive if max pressure occurs prior to TDC as that blows pressure and heat through the roof, because there is no where for it to go. https://www.procharger.com/what-detonation-and-how-can-it-be-controlled Many people think an engine runs off of “explosions” of the air fuel mixture, and that’s incorrect, it’s actually when compared with piston speed actually quite a slow burn, however detonation is the explosion many think of. Some think that Diesels detonate as a normal operation, but excepting for initially starting, they don’t, the fuel burn in a Diesel is initiated the moment fuel becomes present, there is so much leftover heat from the combustion event that occurred fractions of a second ago that it ignites the fuel. But cold diesels will knock, and that knock is sometimes detonation of a partial fuel charge.

My Brother detonated an IO-520 in a Cessna 210 to death trying to keep up with me in a S2R-T65HG, Somehow he thought you got more power when you leaned one out, it took awhile as he called me on the radio saying it sounded like the landing gear were “thumping” the belly, and only one cylinder lost compression so there was no complete loss of power. I didn’t take the engine apart, it was exchanged for a zero time motor, but I’m sure at least one piston had a dime sized hole right it’s center

Pre-ignition is NOT the same, nor is it similar to detonation, but it can lead to detonation. ‘The difference is normal ignition whether it be pre or on time consists of an ignition source where a flame front proceeds at a set speed across the combustion chamber, ignition does not necessarily come from the electrical system, it can for instance be a hot piece of carbon etc. The speed at which the flame front proceeds is set, it’s why on engines that have a much wider RPM range that ignition timing is advanced with RPM due to the shorter period of time there is for the charge outreach peak pressure, and why set timing works well on aircraft engines, because we operate at a narrow RPM band. ‘Now where detonation differs is that there is no ignition source, the entire fuel / air charge goes off at once, there is no source that a flame front proceeds from, it’s an instantaneous ignition of the entire charge. ‘That’s why detonation is so destructive, it’s because there is a huge nearly instantaneous increase in pressure, well above any pressure you will get from an ignition source, and why it often blows holes in pistons, heat follows pressure, and or can cause detonation. Chicken or egg? ‘You certainly can get an NA engine into detonation, Fly full throttle at sea level and start leaning it out, it’s likely you may get detonation and or pre-ignition. ‘It’s what makes me nervous when I read the dissertations on how to run LOP where people are advised to simply increase Manifold pressure to recover any airspeed lost from being LOP, but aircraft haven’t been blowing up engines so it’s apparent that it works, but I suspect that in reality there just isn’t any throttle left to increase, most seeking efficiency go higher, and if your N/A above 6 or 7 thousand it’s likely your full throttle anyway.

Does anyone know how difficult it is to change squawk codes on the tailbeacon-X? I know it’s done through a panel mounted device like the AV-30, but is it cumbersome to do, as in three pages into a menu and scroll and select with the z axis of a button cumbersome?

It can be determined by a instrument that works off of electrical conductivity, and heat treat by Rockwell hardness tester. ‘I believe the factory drawing for that part is about the only way without actually testing the part, the drawings will of course specify material

It’s been years ago but I was at Sun-N-Fun and some guy was walking around general camping writing down N numbers, so I asked him what was he doing. ‘He said I’m a Spotter. I asked what’s a spotter, apparently there are for some reason or another groups of people that track aircraft movements, for some reason, and apparently post this data on internet forums, this is legal, it’s not an invasion of privacy? ‘I was never comfortable with that. ‘I was stationed in Germany for three years and learned a lot while I was over there, they take privacy SERIOUSLY, for example it’s against the law to have more than one phone connected to a line, reason is someone can pick up the other line and listen in. I read that the Google car that drove around taking pictures was stopped almost immediately, taking pictures like that just simply isn’t allowed, maybe now they can do it by blurring faces and car tags etc. But the German’s learned the hard way 60 or 70 years ago to take privacy seriously. ‘I’ve learned that if your wealthy you have your Lawyers contact flight aware and the other tracking agencies and have them remove your tail number from any tracking, look it up, almost all Biz jets say private for an N number. ‘Try calling the local Police station with a tag number because your curious who owns that car and see what kind of response you get. But it’s public knowledge for aircraft? Its one reason I don’t like ADSB. This time I bought the airplane with an out of State LLC, it would be tough to tie that aircraft to me.

It’s very rare for an automobile to outlast the engine anymore, and even rarer for an engine to be overhauled. Most of the time if an engine is to be replaced on say a delivery van etc, it’s almost always a short or a long block, the only time an engine is removed and overhauled is if it’s some kind of rare hard to find motor and you haven’t a choice, so actually cars long ago went to the model of the exchange overhaul, which is what a zero timed aircraft engine is, so aviation is following the auto model. But Auto’s are a different maintenance model entirely, no one does an annual inspection on an automobile, but historically it’s been shown that if you want a vehicle to last indefinitely, then some sort of recurring major inspection is the way to get there. ARMY does it for trucks and tanks etc., but not on a schedule, it’s after major “events”. ‘An overhaul is a form of recurring engine inspection, once in a blue moon, everything is disassembled, cleaned and inspected, and all high wear items replaced. You can try to convince yourself that your doing the same thing piecemeal, but your not. For instance in the bottom end IRAN was the case sent off for inspection and repair, how about the accy case gears for Magnaflux?

Some of you have noticed that the cost of a factory zero timed engine isn’t all that much more than a field overhaul. ‘That’s by design, both Continental and Lycoming have been raising prices of their parts, and discounting their overhauls, one assumes one pays for the other. ‘It’s simply a way to keep the doors open and your people employed since the new engine builds are a fraction of what they were back in the day, I don’t believe it’s they are evil and squeezing the small shops out of business, but that’s occurring, wheth3r by design or not.

Was actually new fabric on my Maule which wasn’t new, the battery vented overboard so all it did was bleach out the paint, none got on the interior. Lifepo4’s and all lithium batteries do have special charging “needs” they can’t be floated and charging has to be terminated when they are fully charged etc. I just came off living aboard a cruising boat for three years, Lithium has a great many advantages there, but is very problematic, for instance when they are full they have to be disconnected from the alternator, but doing so can or will blow the alternator. Plus the cells have to be balanced although many argue they don’t. Most of this can be handled with onboard electronics in the battery if so equipped, but by the time we stopped cruising due to Covid, a true drop in Lithium didn’t exist, maybe now. ‘Issue is that yes lead acid is so yesterday, the charge profile and voltage stability etc of lithium and weight and power density is far superior, but lead acid is a way mature technology and is known. I guess it’s sort of the same reasons we still have Magneto’s. On the boat I had a 660AH bank of Lifeline batteries, they are made by Concorde battery and are pretty much identical to the Concorde aircraft battery. I had them as they are the best deep cycle lead acid battery there is, and yes they cost more

I’d go back to three, believe it or not but three is safer than four. The reason is your more likely to submarine with a four point,so it’s either three or five. ‘Of all of them I prefer a five, but won’t wear anything myself without inertia reels, so currently I only use my lap belts

I’m based on a grass strip, it’s not real smooth either but OK.’ There is also a TLS Mooney based here as well, so far we are fine. ‘Not all soft fields are grass, and not all grass is soft. Once you get used to grass, you’ll prefer it over pavement, it’s kinder on the aircraft.

Gill wet cell are junk, you’ll hate them when one leaks, they eventually will. ‘I had one leak onto my brand new fabric covered airplane, I’ll never have another Gill. ‘The Concorde battery is manufactured in the US by the Godfrey family,they honestly have one goal and that’s to manufacture the best battery possible, and of course that does cost more, but you get what you pay for. Gill prett much gives away batteries to OEM manufacturers, that way they advertise they are the OEM battery, and many people only want the battery that Beechcraft put in their Bonanza or Cirrus and they sell a lot of batteries from that, but they are cheap junk. LifePo4 will be the next greatest thing, half the energy density of Li-Po but they don’t burn, but they aren’t here yet I don’t think, and the aircraft battery market is so small, and getting a PMA and TSO is so egregious, it may not happen. Several put Odyssey batteries in aircraft with a field approval, but there just is no good reason to go through that when a perfectly fine Concorde exists. Ref an IFR airplane and the reserve capacity of a battery as thats what’s going to get you down when the alternator quits. ‘ALL batteries when new are required to have the reserve capacity checked before installation. except a Concorde, Concorde did a cap check prior to shipping, and ALL batteries are required to have a capacity check yearly during the annual, but it’s almost never done. ‘However if you do fly IFR regularity, you may want to insist on the yearly capacity check. Concorde’s are vented, but they can’t leak

I ask as it was my Father’s Mooney from long ago, He sold it again guessing maybe 30 years ago, but it seems it still kicking. N9241M

I looked and unfortunately my ashtrays are sort of square shaped so these won’t work unfortunately

I’m going to bet that All Concorde batteries are manufactured under a PMA to meet a TSO, their Lifeline batteries aren’t, but I bet all Concorde’s are.

You say these things and likely don’t understand them. ‘The Concorde battery is a TSO’d part, originally the LED light wasn’t, there was no TSO for landing.ignts. ‘So Floats Alaska got an STC, Whalen bought the STC from them for their Parmethius landing light, after that I lost track due to getting out of aviation for awhile. but I feel pretty sure that finally, hopefully the FAA came out with a TSO that covers landing lights

For the aviation lawyers. First look up who is responsible for determining whether an alteration is minor or major. I’m certified to make that call. So far as hiding my identity etc, 10 ply tires pale in comparison to what I read daily about what you non certified people are doing under the guise of “hanger elves.

You would think they would be stiffer, they certainly are thicker, have to be, but I can feel no discernible difference in the Cessna, or the Maule I had before. ‘Maule did have short throw Oleo’s, but the Cessna has only spring steel “legs”. ‘I think it really boils down to neither the Mooney, Cessna or Maule has any need whatsoever for the increased load carrying ability of the 10 ply tires, and the increased weight whatever it is and the greater expense just isn’t justified, but it doesn’t hurt anything. ‘Funny thing is that I was sure that on the light weight Cessna that I would need to run lower pressure, but if anything I need to run higher to lift the edge of the tire from pavement

Hold your breath for that. Going to higher ply tires is a “minor” alteration

Interesting you listed Gann, it’s a rather small shop isn’t it? I know a lot of the Maule people like Gann, I had figured largely because it’s a Georgia shop. I believe the parallel valve Lycoming’s he uses new cylinders, but has the angle valve cylinders rebuilt, that seemed odd to me. Oh, I believe the OP is in Turkey, I’m not sure what his availability is of those shops, but assume there is a Turkish dealer that can get him a Factory overhaul.
