In the commentary that I referred to the FAA made it clear that they were watching BOTH existing aircraft that were previously certified, as well as "new designs" based on existing aircraft in Ultralight or Experimental Categories in order to make sure that builders or companies did not try to "make them fit" the category. Dana Overall and I discussed this at length on the net last year and attempted to shed light on the fact that most of the aircraft that are being approved or included in this new category already exist and are being flown, just not regulated. The FAA saw that due to this non regulation this part of the industry was very loose with standards of construction etc... In an effort to improve safety of construction and operations the new category was formed. Although it does make for alot of innovation and opportunity in the grass roots part of aviation, it was not intended by the FAA to promote that, just increase safety as part of the overall Safer Skies Agenda that was embarked on a few years ago as a national campaign by the FAA National Organization. As Jim Ferris so accurately pointed out, by making similar design changes that a builder chooses to the KR, it becomes his design, his named aircraft and therefore has the opportunity to be certified as he applies and the DAR agrees. Sport pilots will be limited to operating aircraft that meet the definition of a light-sport aircraft (see About Light-Sport Aircraft on this website). That includes aircraft in the following categories: a.. Airplanes (single-engine only) b.. Gliders c.. Lighter-than-air ships (airship or balloon) d.. Rotorcraft (gyroplane only) e.. Powered Parachutes f.. Weight-Shift control aircraft (e.g. trikes) As relates to operation, no experimental 2 SEAT aircraft may be operated with 2 seats available (not converted to single seat) by less than a Private Pilot rating appropriate for the category of aircraft ( SEL, SES etc...). Certifying the aircraft as an Experimental, not LSA or ELSA disqualifies a Sport Pilot for operation of that aircraft if it is a 2 seat aircraft. Here are a couple of other notes from the EAA: a.. no flights into Class A airspace, which is at or over 18,000' MSL; b.. no flights into Class B, C, or D airspace unless you receive training and a logbook endorsement; c.. no flights outside the U.S. without advance permission from that country(ies) d.. no sightseeing flights with passengers for charity fund raisers; e.. no flights above 10,000' MSL; f.. daytime flight only; no night flights g.. no flights when the flight or surface visibility is less than 3 statute miles; h.. no flights unless you can see the surface of the earth for flight reference; i.. no flights if the operating limitations issued with the aircraft do not permit that activity; j.. no flights contrary to any limitation listed on the pilot's certificate, U.S. driver's license, FAA medical certificate, or logbook endorsement(s); no flights while carrying a passenger or property for compensation or hire (no commercial operations); k.. no renting a light-sport aircraft unless it was issued a "special" airworthiness certificate; any qualified and current pilot (recreational pilot or higher) may fly a light-sport aircraft; l.. a light-sport aircraft may be flown at night if it is properly equipped for night flight and flown by a individual with a private pilot (or higher) certificate who has a current and valid FAA airman's medical certificate. Builders need to be sure that they review carefully with a local DAR what his take is on these and other parts of the new Regs so that before he spends his money and time building, he has a clear understanding of what he can expect for his effort and how it will be received.

An actual database was too much for my skill level and I gave up on it. Over the past week or so I have been playing with a simple spreadsheet that contains KR data and web links. I have entered a few examples into the sheet as an aid in developing a finished product. The sheet is finished and is hosted at http://www.kr-2.aviation-mechanics.com/krinfo.htm In earlier discussions I was asked if the data sheet that I developed would contain aircraft under construction. I have elected to not include them here. The KR net has listings of builders and their web pages. I want this data sheet to include information about aircraft that completed and flying. My hope is that visitors to the site will be able glean from the info answers to some common questions such as how fast, what type prop or gear, and others. You might be able to estimate what engine size and prop combination will yield what static and cruise RPM and much more. My plan is to cut and past information that is sent to me. If you wish to have your plane listed, send me an off net post. With over 1000 flying KR, this info could prove to be of great value to both owners and builders alike.

I think the problem with 100LL is that it has too much lead in it, which can lead to lead deposits in the combustion chamber and on the valve heads. A little is a good thing, but too much is too much. When we took Mark Jones' engine apart last month, he had significant deposits of lead, and had less than 50 hours on it. Many folks alternate with something like one tank of 100LL and 2 tanks of 93 octane auto fuel, assuming there's no detonation problem on 93 octane. I'll probably do something like 1:4. Marvel Mystery oil is supposed to help prevent lead deposits. And no, I don't own stock in Marvel Mystery oil...

And no, I don't own stock >in Marvel Mystery oil... >Mark Langford ++++++++++++++++++++++++++++++++++++++++++++++++++++++ My experience with auto fuel in the TriPacer for 500+ hours and the KR for 163 hours has been good. I use 87 octane only because of the lower compression of these engines and mix Marvel Mystery Oil at 4 oz to 10 gallon as recommended on the can. I also add from 1/2 to as much as 1 qt. directly to the crankcase at oil change. Any time I used 100LL it seemed to foul the plugs very quickly if the mixture was not leaned, even for ground operations. Some pilots will run with one tank filled with 100LL and one with auto fuel and use 100LL for takeoff, etc., but to me that does eliminate the problem with plug fouling, lead deposits, etc. If I were going to mix I'd be inclined to mix at maybe 3 or 4 to 1 directly in each tank but that would be a hassle. I use baby milk bottles to add the MMO as they are graduated in ounces so it's easy to add just the right mix. I've heard some mechanics say they can tell if an engine was burning auto fuel when they tear it down and say it will cause nothing but problems. One mechanic claimed he had an engine that only went 200 hours and had to be overhauled because of auto fuel. From my experience I'd say there were other factors involved but that is just a gut feel and I have no scientific data to back that up. The Tripacer ran for many years on a 4 to 1 mix and I ran nearly 100 percent auto for the 500+ hours I owned it. When I sold it this spring it had 2240 hours since overhaul. The compression and oil consumption remained constant for the last 500 hours. It is still running fine. I'm not sure how much more you could expect from an engine with whatever fuel you were using. Worst case, it didn't appear that MMO hurt anything and no, I don't own stock in MMO either. The 500+ hours that I put on the engine started with one very low time rebuilt and chromed cylinder which went through breakin with auto fuel. As always, your results may vary..........

A steady diet of 100 LL didn't cause us any valve or valve seat problems. We did see significant scratching in the cylinders on David's 1/2 VW from the lead buildup above the top ring on the pistons. This was resolved by cutting .020 off the side of the piston from the top to the top ring land. After another 700 hours of flight the cylinders and pistons looked like new. Unfortunately, the case failed at that point, so that engine was retired. Valve problems are often caused by the top of the cylinders not being seated correctly causing them to work against the heads. There are several causes for this including: poor chamfer a the top of the cylinders, unmatched cylinder spacers, improper torque, and the front and rear heads not being matched for machining depth. We have seen all of these on engines. The cylinders will literally grind into the head which will cause the valves to have cronic problems as the valve lash keeps tightening up. That is not to say that there aren't valve and valve seat problems as well, but those problems would exist in that particular engine regardless of the fuel. With the stainless exhuast valves, David's 1/2 VW flew for 700 hours without anything more than adjustments at the 25 hour oil changes. Lead deposits: Lead builds up quickly on the pistons, valves and cylinder heads. However, it only builds up a small amount, then continuously sloughs as it builds. I have looked inside aircraft engines with as little as 2 hours on them to see significant lead deposits on top of the pistons. From that point on, the lead constantly builds and sloughs. 1800 hours later, the top of the piston will look very much the same as it did at 2 hours. The one detriment we did observe in the VWs with a steady diet of 100 LL was excessive exhaust valve guide wear as the lead deposits tended to stick to the valve guide stem and grind into the bottom of the valve guide. -Jeff -- "Mark Langford" wrote: Dan Heath wrote: > Why is AV Gas worse for your VW Engine, that Auto Fuel?

Certifying the aircraft as an Experimental, not LSA or ELSA disqualifies a Sport Pilot for operation of that aircraft if it is a 2 seat aircraft. WOW. What's your source for that? If true, that's a huge issue. FAA's rules and comments specifically contradict it: Final Rule FAA comments page 21 says "The FAA believes that there might be confusion concerning what airworthiness certificates apply to light-sport aircraft. Therefore, the FAA is clarifying this issue. A sport pilot may operate any aircraft that meets the definition in § 1.1 of a light-sport aircraft, regardless of the airworthiness certificate issued for the aircraft. An aircraft that meets the light-sport aircraft definition may have any airworthiness certificate that may be issued for an aircraft, such as standard, special, primary, or experimental amateur-built aircraft." EAA's official opinion: "Experimental amateur-built aircraft that meet the definition of an LSA may be flown by sport pilots. The aircraft is certificated as an experimental amateur-built aircraft and must be operated in accordance with the operating limitations given to the aircraft at the time it receives its airworthiness certification. It must be maintained and inspected in accordance with the maintenance requirements for amateur-built aircraft." I couldn't find anything in the entire Final Rule or comments that says a two-seat EAB meeting the definition of LSA would be ineligible for a Sport Pilot to operate. Maybe you were thinking of the two-seat Ultralights that now have to be registered ELSA (not EAB)? ------------------------------ Message: 16 Date: Thu, 18 Aug 2005 09:27:20 -0700 From: "Joe Beyer" Subject: KR> valve adjustment To: Message-ID: Content-Type: text/plain; charset="iso-8859-1" Having flown behing behing a VW for 125 hrs. I've found that VW's have an easier life in an airplane than in a car. They run at pretty much one speed all the time and at one tempature and are not used as an inertia brake, ie. down shifting. When runing 100 LL the valve seats are protected from hammering due to the lead content. Marvel mystery oil is a good additive to help lubricate the valve train when using unleaded auto fuel. I used a 35mm film canister full of it per 10 gal. of gas. Lead oxide buildup in the chamber is a problem and is corrosive. The biggest problem is overheating which causes the exhaust valve stem at the hottest cylinder to stretch which can cause the valves to go out of adjustment. Setting the compression ratio lower also helps in cooling. I usually cruse at 2500 to 2650 in my KR which is lower that in my VW bug. There should be minimal air leaks and plenty of airflow past the engine and through the cowel for good cooling. I've put lots of miles on a '65 corvair and found it to be just like a VW, only bigger, more fuel thirsty, and more powerfull. -Joe Message: 14 Date: Wed, 17 Aug 2005 16:29:45 -0500 From: "Mark Langford" Subject: Re: KR> tappets adjustments To: "KRnet" Message-ID: <02d001c5a372$c99fa7d0$1202a8c0@1700xp> Content-Type: text/plain; charset="iso-8859-1" p wrote: >>i keep hearing about tappet adjustments closing right up or needing doing every5-10 hrs or so even one example where compression was being lost on that cyl which had gone tight anyone got any answers as to what is going on here << >They are probably talking about VW valves.

Subject: RE: KR> Re: Auto Fuel/Avgas To: "KRnet" Message-ID: Content-Type: text/plain; charset="iso-8859-1" One compound that refiners added to gasoline, both automotive and aviation, was tetra-ethyl lead. This improved the anti-knock or detonation properties for the high octane fuels such as 100, 115, 130, etc. aviation fuels. The EPA banned the use of leaded fuels for automotive applications and is pushing hard for the same ban on 100 LL. Problems with leaded fuels are sticking exhaust valves and rings, burned exhaust valves, corroded exhaust pipes and mufflers, fouled spark plugs and plaque in carburetors and fuel injectors. Actually the EPA was not concerned so much about engines and such, but what the free lead in the exhaust emissions was doing to people. Problems cited were still borne and deformed babies, and retarded kids from lead poisoning. Adults are not immune from such nerve damage either. My understanding is there were no production engines designed to run on leaded fuel per se. Rather the designs were for a specific octane fuel. Compression ratio is the design parameter. The cheap way to get the high octane fuel to perform correctly was to add the tetra-ethyl lead. Refiners did figure out how to make high octane fuels work without the lead, such as the automotive gasoline we use and pay dearly for today.
