Its just that simple. Don't you wish PBS worked that way! :-) I really do appreciate each and every one of your individual Contributions to support the Lists. It is your support that enables me to upgrade the hardware and software that are required to run a List Site like this. It also goes to pay for the commercial-grade Internet connection and to pay the huge electric bill to keep the computer gear running and the air conditioner powered on. I run all of the Matronics Email List and Forums sites here locally which allows me to control and monitor every aspect of the system for the utmost in reliably and performance. Your personal Contribution matters because, when combined with other Listers such as yourself, it pays the bills to keep this site up and running. I accept exactly ZERO advertising dollars for the Matronics Lists sites. I can't stand the pop-up ads and all other commercials that are so prevalent on the Internet these days and I particularly don't want to have it on my Email List sites.

Let me introduce myself : My name is Fran=E7ois CHAPPERON, I=92m French, you know ? the ones who eat frogs ! I=92m 54 years old and ultra light flying since 1995 on various machines=85 November 2007, I=92 received directly from the Canadian Zenith factory, my 100% kit of 601 xl . Motor is a Rotax 912 s . I have a parachute BRS . First flight was ran on July the 4th ! Meanwhile , I went through the various difficulties of building with very few plans and information ! I was reading Zenith list regularly, picking informations and not enough sure of myself to get in contact =85 Yes you can be shy at 54 ! Especially when the language is different . I have had some direct contacts and advice with our friend =93cookinwithgaz=94 . Today I=92m pleased to get into the community , =85and to give my point of view about the topic. I went through polishing nearly all of my 601 except parts to be painted .( see pictures on: http://picasaweb.google.fr/chapred It took me about hundred hours with Nuvite stuff and process. (ordered directly by internet half price with France!!!) The result is splendid, and maintenance is not so hard ! The water here is overcharged with calcareous, impossible to wash traditionally. So I use a wet (not dumpy)microfiber glove (water +dish soap) and I dry immediately with others microfibers gloves(generally two) Result is nice and delay the day I will have to re-polish ! Aluminum oxide is a natural barer to more oxidation but I =91m still not sure that a non painted aircraft is as resistant to oxidation than a painted one=85 In the mean time, there is a lot of planes , painted, which present oxidation attacks =85 So what to think ? I read in one of the skipped posts that the aluminium used by Zenith should be more resistant than the one used by Cessna or others=85 Is that =93probated=94 ? Sincerely, Fran=E7ois ________________________________ Message 3 _____________________________________ Time: 03:46:12 AM PST US From: Paul Mulwitz Subject: Re: Zenith-List: Polish, Paint OR not Hi Francois, RVs and (I think) Cessnas use an aluminum alloy called 2024 for skin and other purposes. this is a very stiff and strong alloy that contains copper. It is the copper in this metal that corrodes easily because it is very chemically active. Our planes are made primarily from 6061. This is an aluminum alloy that contains no copper. It is commonly used for household products like screen doors and lawn furniture. It is highly resistant to corrosion in normal environments. It does tend to corrode when exposed to sea salt as you might find in the air near oceans. I believe paint will help prevent corrosion on either alloy. It can be considered a necessity on 2024 and optional on 6061. 2024 is so prone to corrosion that it is usually shipped with a thin coating of pure aluminum on the surface to preserve it. This product is called "Alclad". The coating does work so long as it is not scratched. It is so thin that even a small scratch will expose the copper alloy in the main piece of metal. This means the alclad feature is not satisfactory for long term use to prevent corrosion. After all that, I am taking a conservative approach to corrosion prevention on my XL. I did not apply any paint on internal joints as some people do. I did paint exposed interior parts such as the cabin interior and I intend to paint the entire exterior.

It is not necessary to apply protective coating to the inside surfaces of the airplane in most cases. Most aircraft are made of 2024 aluminum which is not nearly as corrosion resistant as 6061. 2024 usually has a coating of pure aluminum on one side to protect the outside surfaces of the airplane from corrosion. The inside surfaces of an airplane made of 2024 should be painted with a corrosion resistant material or there is a higher risk of hidden corrosion causing damage to the airplane. 6061 is more corrosion resistant and less expensive than 2024 but 2024 is significantly stronger than 6061. An airplane made of 6061 has to be built a bit heavier than one made of 2024 to get the same strength. This is an acceptable trade off on smaller airplanes. On large airplanes, the extra weight becomes an issue so 2024 is preferred.

At idle you are running exclusively through the idle circuit.? As you crack open the throttle, there are transition circuits that come into play.? When you get to 1500 you are running "on the needle" that sticks through the main jet, efffectively closing off the size of the main jet fuel flow until the needle retracts....from 3/4 throttle to wide open you're on the main jet only. Transition circuit problems are very difficult to diagnose.? Sounds like you are running very rich through this circuit.? I would recommend a note to Jabiru USA - Pete knows these things better than anyone.? The other source of information is "The?Carb Doctor" http://www.bingcarburetor.com/ who is the official importer of Bing carbs and parts here in the USA.? The manual is worth every penny.? It's been a long time since I had to access this info, but every owner of an old BMW "airhead" motorcycle has had to deal with these carbs at least once !! After some thought...check your float height.? If it is set too high that would cause a rich running engine.....

Not exactly severe conditions. My skins were stored standing upright against the panelled walls of my basement (Where a dehumidifier was running 24/7) in their paper wrapping.

The paper it came wrapped in is to protect it during shipment. In a damp environment, the paper can hold moisture which can not only promote corrosion directly, it can promote biological growth which can be another source of corrosion. Even with de-humidifiers, basements tend to be damp and if air can't circulate around the metal to purge the moisture, you can end up with a favorable environment for corrosion.

I finally mounted mine near the rear access panel at the back of the plane. I first hooked the unit up and connected to the Dynon before permanently mounting it. I had an inexpensive magnetic compass that I used to verify the heading of the plane. This also validated the magnetic alignment of my workshop on our plat. The plane was setting parallel to the building. I planned on putting the electronic magnet behind the passenger seat. I couldn't find anywhere in that area that it read accurately. The flap torque tube was causing a lot of magnetic interference (ferrous), and when I got it far enough from the flap controls the steel tube framing of the step started taking over. My final location in the back of the plane is very convenient and easily reached and there was no measurable deviation due to local magnetic fields.

I know that regular cardboard shouldn't be used to back framed pictures or documents for that reason. It probably shouldn't be in long-term contact with any sort of aluminum, even in conditions of low humidity. Incidentally, T-6 refers to the heat-treatment rather than the alloy itself. The alloy is 6061, so the full designation is 6061-T6. It does give good service in aluminum canoes and boats, so it must be at least somewhat corrosion resistant.

Well I would say if the mount is the same as the one you are replacing and doesn't change the position of the engine it isn't a major modification but some would. I guess it would be up to the DAR. If so, is that test period as restrictive as the Phase 1 so that you have to do it solo? Others can answer that better than me but I would say if you revert back to Phase 1 the same rules would apply as the first Phase 1.

They are not meant to be adjustable, but they are....IF you don't mind doing a little soldering. They are mounted on a plastic rail and are almost infinitely adjustable. You may need to lengthen (or shorten) a wire, but the limit switch will just snap into a new position on the rail. It's actually a very simple operation...but it will probably void any warranty that comes with the unit. I am using an actuator similar, if not identical to the one Scott used. It has a 200 lb force stroke....and moves at about 1/3 inch per second...perfect for flap control. I used a 9 inch actuator because it was the right length to fit between the two pivot points. That way I didn't have to fabricate an extension. Then I adjusted the limit switches so that I am using about the middle 3 inches of travel. http://www.firgelliauto.com/product_info.php?cPath=75&products_id=2 (I see they're on sale!)

Bill Clapp is testing our rear unit on his KR and has 25 hours on it and he is very happy with the performance. The pieces you saw in the picture is sanded foam with a coat of epoxy to protect the foam from the tooling gel coat as it will melt the foam (Don't ask me how I know) and ruin the master. I am working on a 2 piece cowl also for the corvair and everything will be at Sun and Fun next year. In Jan.

We have a test pilot that we use that is more experienced to do the first flights of new parts, I don't as a student do it.
