MGL isn't a certified unit and cannot be used in a certified airplane. That said, in the homebuilt community MGL doesn't have a bad reputation though it doesn't seem to be as popular on high-end homebuilts.

Interesting review. I think you meant "KNS" several times where you typed "GNS" when comparing against the GTN. I don't think that you meant to refer to the Garmin GNS 480, did you? Regarding the observation of entering waypoints, in the KNS 770 manual (link below) on the top of page 14 (and in surrounding pages) it is shown that you can enter waypoints by double-tapping the screen which will bring up a QWERTY screen to enter the name of the waypoint. Perhaps this isn't in the demo. I'm curious is this type waypoint entry on the KNS 770 is similar to the GTN models. http://www.bendixking.com/HWL/media/Pilot-Guides/D200909000026_2.pdf From a cheap ba$tard stanpoint, the 770 seems to be a strong contender against at least the 650. For about 1 AMU more than the GTN 650 you get a larger screen and the ability to create ad hoc holds (it's probably more fair to compare the 770 to the 650 than the 750). XM weather for the GTN costs an additional 4 amu whereas King's alternative is 2.5 amu or much less used. KT74 is 2.6amu vs 4.4 for the Garmin GTX 330ES. I don't know about the King ADS-in alternative, but a kitted-out KNS 770 should cost several thousand less than GTN 650 if you have add-ons behind the panel.

In general terms, the CGA 870 (brass or chrome) are garden-variety mobile medical oxygen valves. There are countless threads and webpages on the subject of preference for aviation use. For a pilot who needs an O2 system for his/herself only, and who has easy access to free or inexpensive oxygen, I wouldn't spend more than $100 for a new oxygen setup ($75 on a cylinder, $25 on a simple regulator) plus $10 for several disposable nasal cannulas. I'd then spend $140 on a wrist oximeter and be done with it. $250 all up with an continuous oximeter setup with a hypoxia alarm that you might be able to hear. To operate the O2, just turn the regulator valve up enough to keep the O2 over 90%. If you need to refill your own: Welding 02 tank (rented vs purchased, check your local prices) Fill adapter Ebay <$100 (search "Oxygen Transfill Adaptor CGA540 CGA870 Aviation Veterinary Medical") Then you're in business.

I would assume that may of these tanks at give-away prices on Craigslist are timed-out and are due for hydrotesting. If your tank it due for testing then getting it refilled will be a problem. I see no reason to get anything smaller than an E cylinder. I wouldn't go smaller as refills generally cost the same regardless of cylinder size. Also, if you go E and are able to work with a local medical supplies, swapping E tanks is easy. For new E tanks for around $70-80 (instead of the $200+ that MH charges), check out: http://www.americanairworks.com/oxygenrefilling2.html ($77 for one, $63 each for 2-5 at current prices)

Quite an unforunate incident. In this specific circumstance, in response to the facts related, I would replace the cowl fasteners, review oil consumption/loss issues, inspect the pitot, and if all good (i.e. you determine the airplane is safe/standard on these issues) document the same and fly home. Don't look back. If I had more energy I'd take a few minutes to video the bottom of surrounding planes and cowlings for missing fasterners and keep this in my files.

If you don't have a cooling problem then it means that you have a cooling drag problem. On a related note, has anyone ever heard of an STC to add a plenum to a Mooney? Currently or recently there was a vintage Mooney for sale that had a plenum in place on the engine which otherwise should be a major mod with DER approval etc.

Between roughly 1946 and 1970 the US enjoyed global production dominance while the rest of the pre-WWII industrialized countries were rebuilding. During this ~25 year period the US greatly built up and reinforced its infrastructure. After roughly 1970 the rest of the industrialized world began to catch up. In the last 20-30 years S. Korea, and namely China haved entered the scene in force. The world is different now, but some of us seem to have a hard time accepting the reality for what it is and like to hang the blame on entitlements or immigrants or the like while others of us accept the external forces as being dominant. Regardless, to keep everyone happy, the US govt has figured out a way to continue to prop up our economy. It helps that the rest of the world considers the US to be the most politically stable and therefor best place to dump their surplus capital. But that doesn't mean that the US economy is strong, or that the future is intrinsically bright. Rather, so long as everywhere else continues to be a dump, we're the best thing going. If this reality sounds unpatriotic, get over it as we have hard work to do. The insurance commission is a joke. I haven't been to church enough to love my neighbor the paper shuffler who can somehow afford a house, car, plane, boat, vacations, all through shuffling paper. There are govt beaurocrats and there are private side beaurocrats. I simply can't listen to people proclaim to be "conservative" who themselves leech off of the producers. We need insurance, just like we need roads and a strong defense. But we don't need bloat, whether governmental or private. I just wish modern "conservatives" would be as against private-side bloat (where regulatory captures and/or monopolies exist) as much as they are anti-government. Dave, I'm not pushing for the government to run healthcare. That being said, who would you prefer run healthcare? The VA? Morgan Stanley executives? Kaiser? Who? Government control=Cronyism, bloat, works program, nepotism, waste, politics, money influence, hard to fire dead wood, etc Private control=Cronyism, less bloat, rare works program token employee, nepotism, waste, politics, money influence, profit, can fire people unjustly, requires regulation (per the heads of private industry!), etc Of the two choices, I prefer the one that is 1)the most sustainable, 2) offers the most freedom, and 3)is more efficient. I otherwise don't see one type of entity as inherently better than the other. I do appreciate that it easier to conceptualize the world as being good vs evil. Research says many of us are disproporionately wired to think in terms of good and evil. These people seem to cause the most problems.

Food stamp use is most prevalent in red states.

Hi John, Have you looked into the concentrators recently? How often do you go above 18k? How many passengers typically? If typically solo or 1 passenger then a concentrator or two would seem best with an E tank "borrowed" from work with cannulas as an emergency backup to the concentrators. If using tanks, I'd buy a large welding cylinder off ebay and refill the smaller E tanks in the hangar. Otherwise why not just borrow-rotate E cylinders from work?

While the initial symptoms of carbon monoxide poisoning and hypoxia are similar, carbon monoxide poisoning can cause (if you believe the research) permanent brain damage (amongst other bad things) that can be insidious vs carbon dioxide accumulation that provides no similar damage concern and can be cured in seconds with increased breathing and/or supplemental oxygen. In such a discussion it should be noted that pulse oximeters are not useful to evaluate for potential or presumed carbon monoxide poisoning. Put simply, the pulse oximeter will typically provide a normal "oxygenation" value despite the presence of a critical amound of carbon monoxide poisoning (i.e. carboxyhemaglobin). José's idea for the home depot design is reasonable though I use a portable. Portable is nice because a) it's less expensive, it's usefull to test against the CO monitors that I have at home. I'd strongly encourage everyone to have CO detectors in their homes (but that is another issue).

David, you may be many great things, but you apparently are not apparently familiar with regulatory capture. Regulatory capture is not evidenced by abusive agencies on witch hunts. It is not government inefficiency on a monumental scale. Regulatory capture is the circumstance where the government agency that is suppose enforce or otherwise keep an entity "honest" has itself been "captured" by the entity that it is supposed to regulate. For example, a toothpaste manufacturer can sell a product containing ingredients known to cause cancer because the FDA allows the manufacturer to cherry pick the data that it submits to FDA. Does this mean that we should get rid of the FDA? No. Does it mean that we need a bigger FDA? No. Do you really think that FDA approved industry studies because FDA was simply lazy? Regarding "big government." People on both sides of the isle want more efficient government, but they simply articulate it in different ways. If someone isn't willing to pay for "big government" then they are not for big government, no matter how their mouth moves. If we had highly efficient government next week the majority of people would be happy. I would ask you to strongly consider the alternative reality (call it the universe that your enemies are living in) is that the principle problem that we face is regulatory capture and too much money in politics. Even if you clear the congress tomorrow, the "evil industry" side will just leech onto the next group. Of course industry has a right to lobby for itself, but no so far as to sell us cancer causing crap and steal 500+ billion of our retirement savings every year. Regarding insurance, again insurance is a reasonable thing and I buy it for obvious reasons. But why should I have to pay extra to support all the insurance lackeys in the insurance industry who don't have the skills to find a better job? There is no avoiding the simple fact that there are a hell of a lot of people in the insurance industry who buy all kinds of crap and afford all kinds of lifestyles for offering the rest of us absolutely nothing. Like the welfare queens they have learned a way to game the system, only it isn't politicaly correct or cordial to point that out as many of them have made it up into our social circles.

So you are a fan of the mandate that everyone must purchase health insurance then, yes?

David, I suggest you review the concept of regulatory capture in detail. The fact that regulatory bodies need to exist and that they are captured suggests that both companies and government are bad. Call the state insurance commission? You mean ask the government for help to ensure your rights are maintained? You honestly say I have the freedom to switch companies? David, I own several vehicles. Apparently even though I can only drive one at a time, I have to effectively pay separate liability premiums. In what state does the insurance commission prohibit this practice? Which company will effectively charge me for the most "risky" vehicle and then a $5 fee to add the other VINs to the policy? I don't think that I've ever met anyone who wanting bigger government. People want more efficient government, just like they want more efficient everything else. Saying anyone wants bigger government is a straw man argument at best.

Do you like giving a substantial portion of your money to insurance baboons all your life? Let them determine how much of your money they will take? Let them feed their families with your family's money? I don't understand the love for insurance baboons but the hatred for government baboons.

Your point on tact is well taken. In response, to paraphrase a guy that used to sit in on some of my lectures in college, extreme sarcasm in attacking ignorant anarchism is not a vice. To point out an individual's frank narcissism seems an attack on the player and not the game. The issue I have is when that individual's narcissistic supply goes from the interpersonal realm (torturing those around him) to the political realm where his over assured but ill-informed ideas damage at minimum the collective wisdom. The founding fathers were elitists for a reason--they chose a representative democracy (or republic if you are new to the vernacular) to buffer those with responsibility from those with more emotion than sense. Good luck changing one of the most brilliant minds on earth.

There's just no talking to some people. https://www.youtube.com/watch?v=FWBUl7oT9sA

"Big government" proponents argue that bigger government is needed because of the consequences of the relative few that abuse their rights. This conservative prefers one inefficient money sucking goon squad to two (zero would be better but there will always be the free riders and sociopaths amongst us that need oversight and encouragement to do the right thing). Sucks to be on the wrong side of history, but you can't justify your "conservative" earned income based on the same argument as big government proponents.

The social contract theory underpinning the concept of insurance is indeed sound. Where insurance becomes a racket is when the insurance "system" begins to defy social contract theory and/or perfect market theory. Those in the insurance-complex personally benefit by skimming from both the insured and the end-resolvers (e.g. mechanics, contractors, physicians) who actually do something beneficial for society other than inventing arguments to justify their existence (e.g. insurance lackeys, trial lawyers, etc). I would too be angry if I was suffering from the cognitive dissonance of wanting to be a conservative, wanting to hate people (which is by no means synonymous with conservatism but is demonstrated by CINO's for the past 30 years), all while I was sucking on the NGO legally justified tit of my fellow American. It might be 100 times worse if I was a narcissist.

What a different life some of us would lead if they were not able to suck money out of the rest us via the insurance racket. I wonder what other "skills" they would have to earn a living, and what kind of living that would be. I wonder if they might be humbled. And how much more money Timmy would have to spend on everything else if not paying for the existence of said insurance lackeys.

To the OP: I'd swap one mag for the EI. The EI theoretically will last longer than you and it will pay for itself in 400-500 hours. It might even give you a little speed/climb nudge.

No. Instead to the well-meaning young man who has grand ambition coupled with naivety and weakness in controlling his emotion such that his otherwise extraodrinary skills are susceptible to being manipulated by others in a manner that causes him to act against his own best interest. If you ever see your fellow Americans as terrorists then you have been played.

I personally tell Timothy Stansfield Pemberwell Wilthrop every night that we are forunate to live in a country where it is possible to double our fortune every 10 years by convincing the upper 0.2-1% of the population that their problems are caused by the lower 99% percent of the population. I teach Timothy Stansfield Pemberwell Wilthrop how to work with our "like minded" friends in other countries on policies that will continue to keep our respective lower 99.8% fighting amongst themselves and not ask about us. I also let Timothy Stansfield Pemberwell Wilthrop understand that it is okay to promote self-sufficiency, to include user fees for our Gulfstream, after all it is only fair that the bottom 99.8% should not subsidize our aviation activities.

I am doing research. I asked you. You seem to have an answer for everything. Are you telling the truth or not?

The high-end model of anything is typically reliable. That's one of the main criteria to be "high-end." Good engineers are supposed to design things for the rest of us idiots. A good engineer doesn't design something that requires another engineer to make it work. Can you provide a list of installers who will provide a fully functioning 750 without having these major issues? If you can't, you are full of it.
