OK, so I had just spent an hour dealing with the KRNet only to have my replies sent back because they were too long or what ever. If there is new criteria that post must meet so that it may be allowed on the list someone please post it. I know a lot of us have complained in the past about KRNet sometimes being a waste of time and I just felt that yesterday it was a COMPLETE waste of time. Thank You.

Its just my opinion but mogas just isn't worth it. It all depends on what part of the country you live in. Around here, 100LL is $2.00/gal, for flying club members and $2.20 for non members. Mogas is currently $1.16, $1.26, $1.36 for 87, 89, 93 octane. Even better, we had a gas war this summer and 87 got down to $.92 here and as low as $.87 in South Carolina, just 20 miles away. About half of the planes on the field have auto gas STC's . It's fairly common to see the weekend warriors pull their plane over next to the parking area and haul out 5 gallon cans of gas from their vans.

There has been a discussion here about having to have a re-inspection after making "significant changes" to homebuilts, and apparently meetings between EAA and FAA have resulted in some "lightening up" of the interpretation of the regs. Now all you have to do is document the changes you make in your aircraft logbook, test fly for 5 hrs. to verify things are OK, then sign yourself off as OK again. There were discussions here that indicated there is a wide spectrum of what might be a "significant change", but even a prop change, adding a flight instrument, adding wheel pants, etc. could be interpreted that way, especially if it affects CG or flight characteristics. No problem anymore, apparently. There should be more info forthcoming, but for existing airworthy homebuilts there seems to be one more little hoop to jump through to be able to self-recertify under this new interpretation. The magazine said they would have more info in next month's issue.

May just be coincidence, but when I use mogas, I find a lot more crud in the gascolator on preflight. The other reason for using mogas is to try to get a decent fuel without all the lead that is in 100LL.

Hmm, I don't see that problem here. I go through 25-30 gallons of lawn mower gas a year and I've not found any crud in the cans or the gas tanks. I've got an old push mower that I use for trimming with and this summer I had to remove the gas tank to clean out all the grass clippings, but did not find any dirt, gum, varnish or other crud. If you are getting crud, you may want to switch suppliers. Old gas stations with steel tanks can get really nasty in the bottom. Think what that stuff might be doing to your nice late model Fuel Injected Turbocharged sports coupe. BTW; something many folks don't know, mogas is quite hydroscopic, even without any alcohol added. In 90 degree summer weather it will absorb some amount of water without any visual indication. When winter comes, this water will then chill and drop out of suspension. A easy check for dissolved water, is to test a small amount of gas by dropping an Alka-Selzer tablet in it. Any water present, the gas will start fizzing, no water no fizz. >The other reason for using mogas is to try to get a decent fuel without >all the lead that is in 100LL. My experience is that the VW does not >like the lead. Neither does C-0-200 and 0-300 engines. It causes all sorts of valve problems. The small Lyncs seem to tolerate it though. The trouble with 100LL is that these low compression engines just don't have high enough combustion temps and the fuel burns too slow. This is wasteful as a lot of unused energy is pumped out the exhaust port. This also stresses the valves. It almost makes you wonder if 100LL was tailored to the Lyncomings.

Maybe our 8.6 to 1 >compression and proper leaning may be helping us here. No doubt about it. I would expect anyone running 8 to 1 or less to have some amount of problems with 100LL. Leaning can help some, the overall shape of the combustion chamber has a lot to do with it. When you open up the chamber for a turbo engine, you have to remove most of the squish area. This will cause a hotter burn and more complete combustion, even though you have lowered the C/R to around 7 to 1. In case anyone is wondering, that so called squish area doesn't contribute much to chamber turbulence, like many think. It is really a quench area, and the effect is to cool and dissipate the flame front, as it passes over the lip. This is why the Corvair 9.25 to 1 heads work better then the 8 to 1 heads. They have a larger quench area and are more forgiving to timing and octane rating. OTOH, large quench areas have poor emission qualities and have largely disappeared from current engines, to be replaced with $2000 worth of electronics, to do the same job while maintaining a cleaner exhaust. BTW; large quench areas were invented by Chevie engineers when they were developing the first little 265CU. IN. V8 mouse motor. They were looking for a way to make the cylinder heads as narrow as possible for space reasons, and stumbled on to the advantages of better combustion by accident. The original Chevie V8 came out with a 1 point higher compression ratio then was considered normal for the fuels of the day. >Also the electronic ignition with wider gaps might be helping? Definately. A good CDI will actually clean up dirty plugs in an old engine. I did that to an old Dodge van with a 318 V 8 buried down inside it. It was an all day job to get to the plugs on that old rust bucket. I slapped on a home built Delta CDI and my brother ran that beast for another 3 or 4 years.

However, since that time I have received several personal emails asking if we would ever consider making them again. The problem has always been that these pieces are an incredible hassle to manufacture. The per-piece reject rate is fairly high, so every time we decide to have these puppies made, we have to have another batch made, and then another batch, until we have the correct part count. We have always tried to keep the price as low as possible, so there's really not much in it for the cost of the hassle. But, if you guys really want TET to offer WAFs - I would like to know. I'm am looking for a rough head count of guys interested in purchasing a set of WAFs from us. If the demand is out there, we'll do it. If not - I'm not going to waste my time. I'm am not looking for a commitment - just a rough idea. If you're interested send me an email mailto:drdean@execpc.com At present, landing gear brackets are not in the plan for TET, but they might be. The brackets that we can have made are sized to fit the AS5048 forward spar (spar caps are further apart then for the RAF48) and will accept the Diehl legs. The set welded up, powder painted and ready to mount (no legs) will run about $250 - $275 depending on how many orders we place. If you're interested, send me an email telling me so. If the demand is high enough, we can have a bunch of these made up for you. Before the order is placed, I would need to have a firm commitment.

I've always wished there was another way (other than resorting to turning on the white flashlight) to read the charts more easily. I'll admit to my pacifist nature and just accepting the red cockpit lighting. My awareness changed a few years ago and will never be the same. I was ferrying a friends Grumman from Missouri to Oregon a few years ago during the dark of December. I didn't stop for sunset and my flying went on close to midnight. Before my trip my friend gave me a sample of a flashlight he had just built up. It had red and green LED light bulbs in it. WOW, what a difference! It was like going from "formatted to fit your screen" to letterbox. Suddenly I could see the rest of the story on the charts. I will never go back to plain old red again. No more fatigue and frustration trying to squint out the magenta lines. Recently, this guy has added a blue LED to the flashlight and now I can see the yellows of congested areas clearly. It's remarkable how long we can get stuck in a rut and not ask "how do we get out of here." I've brought this flashlight to my EAA chapter meetings and get the same reaction, "wow, this is great" and "why haven't we done this yet?" So, the bottom line to all this espousing is that red and green LED's let you see so much more. When you add a blue you get the effect of "white" light. His little light is about the size of a pack of cigarettes. Even with all three lights selected, it isn't powerful enough to deteriorate your night vision (you can still see around you after you shut the light off). One other thing I like about this flashlight and LED's is their solid-state design. They are much more reliable and need much less battery. (Disclaimer: I'm not an ophthalmologist or expert, this is just what I have been able to deduce from books and studies of the subject over the years). If you look at a response curve showing the response of the human eye to different colors of light, you find that we are least sensitive to red and most sensitive to blue. This is the reason that red light was chosen long ago to "preserve night vision." But this response curve is misleading. The real killer of night vision is INTENSITY, not color. That is, a BRIGHT RED light wipes out night vision worse than a DIM light of ANY COLOR. But the red-night-vision connection is woven so tightly in to aviation, that it's been kind of a sacred cow until recently. A few years ago, the military began using a blue-green mix for night operations, and this forced us all to take a new look at the traditional red-only rule. The other problem with red (or any monochromatic (single-color) light) is the color differentiation problem: sectional chart magenta airports fade away, important notes printed in red become invisible, and should you suffer a scratch (as one commenter noted), you can't see the blood! A dichromatic light (a mix of two colors) greatly increases color differentiation, though it does not let us see "true" colors. For example, the blue-green light of the Gamma3 flashlight makes almost any color visible, except for a very narrow range of blue-green. Reds and magentas stand out strongly on a white background, but they appear dark gray, not red. To achieve both differentiation and true color perception, the light source has to contain all three primary light colors, which are red, green and blue. To sum it all up, for preservation of night vision, use a DIM light of any color; for color differentiation, use at least a two color mix; for perception of true colors, use "white" light. I put "white" in quotes because there is a huge range of mixtures of red, green and blue that the eye (or really, the brain) will perceive as "white." Of course, all of this is what led to the design of the Gamma3 flashlight--red for the classic night-vision protection, blue-green for best color differentiation, and white for true-color perception. You can read about the Gamma3 flashlight at www.gdi3.com or call 503-598-8079 and request a data sheet. - dan" Larry Larry A.
