    Subject: The Puzzle of the Yellow Fuel
    Here is the mystery. This is a brand new airplane. AMD-manufacturerd CH601XL with all new everything and 20 hours on the Hobbs. It has never been fed anything other than blue 100LL. The fuel samples from each wing tank are always blue and have never shown any water or strange stuff. But, the fuel samples from the Gasloator are always unmistakably Yellow. Oh, and the engine always roars sweetly. Does anyone know definitively what's going on? My theory is that the brass/copper alloy gasolator, being new, is giving some color to the fuel sitting in it. (Yes, as I'm writing this I realize that I should check the sample color right after flying... thus the value of public confession. Although... I have pulled as many as 5 sample tubes of fuel from the Gasolator during pre-flight and they were all yellow.) Has anyone else experienced the yellow tinge?

    Subject: Re: Landing Lights
    Hi Bill, I opted for navigation lights and strobes but no landing lights for my XL even though I cannot legally fly at night. I hold a private license and have had adequate night flying training and experience, but plan to operate under Sport Pilot limitations so I don't have to fight for a "Special Issuance" medical certificate. I believe the landing light is not required by any regulation for night operations. It may have value - primarily in daylight flight - for collision avoidance, but in my humble experience is mostly worthless for use in the dark. My personal thinking is that while I will not plan for night operation I might get caught with a late landing and want the minimum lighting for legal flight at night. I think that is the navigation lights, and the strobes just make sense even if they are not actually required. If I get caught making a night landing with my Sport Pilot restrictions, then I guess I will face the music.

    what i rad is that planes have various metals touching at any given point, (screws, bolts, chrome molly, aluminum, etc. protecting the skin from water is not so much an issue as protecting from electrolysis. that is why we paint zince between pieces, and use cadmium washeers with screws and bolts. In st. petersburg FLA where we live, we have salt water on the air field. we primed the entire plane in and out. we alos painted light grey the entire interior. Aluminum 6061 has good anti corrosion properties and under normal weqar and tear wilkl protect itself, we at the waters edge need a little help.

You should not have to heat the mandrels before grinding with a Dremel (or any other grinding tool). Heat is only required if you machine them. But better yet, just unscrew the mandrels from the air riveter and screw them into the hand riveter, most are interchangeable.

    Subject: Re: propellors
    One factor with prop length doesn't seem to have surfaced in the latest discussion. That is the fact that the propeller is mounted in front of the fuselage. The airflow from the central portion of the propeller is blocked by the front of the fuselage, so this is mostly wasted energy. A longer propeller has less of its rotation disk blocked by the fuselage, so more of the energy spent by the engine is converted to thrust. An extreme case of adding shorter blades would have all the airflow generated by the propeller disrupted by the fuselage and a plane that could barely taxi.

    Subject: Re: vg's
    No doubt about the fact that any change to the aerodynamics of an aircraft is reason to have to fly off the test phase again and probably trigger another inspection. The main problem may well be legal, as you said the original builder is responsible for the airworthiness of the plane...... even after it is sold.... possibly sold several times. Gary Wolf, president of the RAA (Recreational Aircraft Association) asked the question, "How would you feel if a plane you built were used for training purposes after being sold?"? Remember you would have no control over how the plane is used or maintained. You do however still have the responsibility of the original builder. Noel -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of R.D.(Ron) Leclerc Sent: Friday, December 15, 2006 7:28 PM Subject: RE: Zenith-List: Re: vg's Noel I agree... this is for the Canadain guys wanting to remove there slats only! This is a direct quote below from... COPA's -- "COPA Guide to Amature-Built Aircraft"... in Canada Under - Reviewing The Rules - CAR STD 507 Appendix C .... The only thing is if Transport Canada's final inspection and approval was with the Slats on then it looks like they should be informed otherwise you would be flying illegal and if something should happen... that's where insurance companies will get a little excited about! Design Changes Many builders of amateur-built aircraft incorporate changes in the aircraft they are building, whether the aircraft is being built from kits or plans. One of the great advantages of the amateur-built category is that this is allowed. It is up to builder to decide whether the changes are warranted and how they will be carried out. Both the CARs and the courts have been clear that when the aircraft is completed it is the builder who is responsible for the airworthiness of the aircraft, not the original designer or the manufacturer of the kit from which it was constructed. This is a good thing as it allows the builder to make changes, but it carries with it the responsibility to do a good job in making changes to a design. Ensure you know what you are doing as you will be solely and legally responsible for the outcome! If you are not confident in your abilities as a designer then get professional help from the original designer or an aeronautical engineer. Otherwise don't make the changes to the design, especially when they involve changes to the structure. There should be no confusion where the responsibilities are before the build and after the build after reading the above... the key word's are "Ensure you know what you are doing" Ron Leclerc Winnipeg,MB On Tue, 12 Dec 2006 21:58:29 -0330, Noel Loveys wrote: > Mark: > I don't' think you would have problems removing the slats to get > the plane passed the MD-RA I've seen greater design changes made > to aircraft that passed.

    Subject: FAR quesion on major mod
    Does anyone know what FAR reg deals with major modifications to an Experimental? I sure could use some help. I have several feelers out, but thought I would contact the list for your input. I have finished my 601HDS Spring Gear conversion. As some of you may remember, I had a weld failure on the left main at the bottom plate that attached to the 2 inch tube. I decided rather than reinstall the same type gear, I went with the spring gear from Grove aircraft. I have completed the project and have done my new weight and balance, and completed several high speed taxis along with lifting if off the runway and back down several times, and so far so good. So my question is: what paperwork do I need to complete, do I need to have a DAR reinspect it, or can I make the notations in the logs, is there another Phase I flight testing and for how long? Anyway, if anybody knows what FAR reg deals with that, please let me know, cause I'm getting many different opinions. Thanks for your help Jim Olson Murphy, NC CH01HDS, N56BJ 288 hrs

    Subject: Re: Landing Lights
    According to the FARs: Anti-collision lights (strobes) are required on all aircraft, day or night. Nav lights are only required from sunset to sunrise. A landing light is only required on aircraft operated for hire. A landing light is not really required for landing on a lighted runway. I've landed without a landing light several times, mostly because the cowl mounted landing lights tended to have a short service life and would often quit unexpectedly. Landing lights are good for alerting you to deer on the runway though, they're very hard to see otherwise.

    Subject: Re: Pulling Stainless Steel Rivets?
    From: "PatrickW" <pwhoyt@yahoo.com>
    OK Guys - I got it. Here's the solution. Short Version: Unscrew the nose piece "a little bit". This allows the hand riveter to "bite" onto a different section of the shaft. This worked for me. Long Version: I carefully measured the length of the rivet shaft that was still sticking out. I then pumped the hand riveter 300 (three hundred!) times. It felt like I was getting just a hair's worth of "bite" at the end of each stroke, so I kept going - thinking that I was getting it very slowly. Then I measured the length of the protruding shaft. No change! But I did notice some small metal "filings" in the area. Something was wearing down someplace. I twisted the hand riveter around to "get a different angle" on the rivet, and the very firt pull "felt different". But then all the subsequent pulls felt the same as before. I realized at that point I might as well have been trying to squeeze a watermelon seed. But I knew what the problem was at that point. I took the nosepiece out of the riveter and looked inside to see how it worked. I needed to be able to "bite" onto a different section of the rivet shaft each time. I simply unscrewed the nosepiece a little bit and gave it a try. What do you know - it worked! 2 pulls later I heard a resounding BANG and the Stainless Steel rivets were installed. :D Tail section done. On to the Wings...

    Hmmm..... not knowing any better, I just used the pneumatic puller that I bought from Mark and David at CAN-ZAC when I took their rudder workshop. It came from a Canadian outfit called Princess Auto. It didn't break and I've pulled a lot of rivets since. Maybe I just got lucky.

    I don't know which FAR, but you can usually find the requirement listed on your operating limitations. When I changed engine types, I filled out a new Airworthiness Application and sent it along with a letter explaining what I was doing to the local FSDO. In the letter tell them a little about the mod, and explain what you plan on doing for testing. Leave your contact information so they can call if they need more information. One thing that I wish I had done was send the letter "return receipt" as I have no record of them receiving it.

    Subject: Re: The Puzzle of the Yellow Fuel
    The fuel pulled from my gasolator was discolored for awhile after I started flying 633Z. I didn't note when the yellow to dark yellow color went away, I haven't seen it for 1++ years. I attributed the color to leaching of the rubber fuel lines. Easy to test - put some fuel in a new line, plug the ends, and check for color in a week or two. If you don't have rubber lines check for other sources that could leach.

    Subject: Corrosion Protection
    I see from reading some of the other subjects (i.e. storage of components) that there might be some problems with paint sticking where there is corros ion protection. I am using zinc chromate to protect my plane. Am I going to have problems with paint sticking to these parts? If so I'll be more careful where my zinc chromate ends up (i.e. nothing on outside surfaces) Ryan

    Subject: tail dragger
    Hello, all I am presently assembling the outboard panels of my 601-HD, which I have always thought would have tricycle gear. But, for some reason (food poisoning, alignment of planets, subliminal messages, global warming, God knows) I have been thinking about a tail dragger configuration. I know this is a good topic to start a 3-week long thread, but the issue is too old for this. All I'd like to know is what are the changes/pitfalls in the construction? I know it gets some simplification by deleting the nose gear - but then you add a tail wheel. If I recall well, the main gear is installed between nose ribs, so that's probably the only pieces that go to waste: 4 nose ribs. My spar is already built, but I am guessing it requires no changes. Anyway, I'll order the TD plans on Monday. Even if I decide against it, it's only $25. And, btw, how many TD owners/builders subscribe to this list? Please respond to this particular question directly to me: carlossa51@gmail.com Cheers Carlos Montreal, Canada

    91.209 Aircraft lights. No person may: (a) During the period from sunset to sunrise (or, in Alaska, during the period a prominent unlighted object cannot be seen from a distance of 3 statute miles or the sun is more than 6 degrees below the horizon) (1) Operate an aircraft unless it has lighted position lights; (2) Park or move an aircraft in, or in dangerous proximity to, a night flight operations area of an airport unless the aircraft (i) Is clearly illuminated; (ii) Has lighted position lights; or (iii) is in an area that is marked by obstruction lights; (3) Anchor an aircraft unless the aircraft (i) Has lighted anchor lights; or (ii) Is in an area where anchor lights are not required on vessels; or (b) Operate an aircraft that is equipped with an anticollision light system, unless it has lighted anticollision lights. However, the anticollision lights need not be lighted when the pilot-in-command determines that, because of operating conditions, it would be in the interest of safety to turn the lights off. > According to the FARs: Anti-collision lights (strobes) are required > on all aircraft, day or night. Per (b) above it looks like anticollision lights must be on if the aircraft has them. But not all aircraft are required to have them. Certainly this would keep the no-electrical-system crowd in their hangars even during the day. Bill Mileski Read this topic online here: http://forums.matronics.com/viewtopic.php?p=82007#82007

    Subject: Re: Corrosion Protection
    Ryan, I'm using Zinc Chromate on the interior parts. I don't worry about overspray to the outside. In fact, I sometimes lay one skin on top of another to prime the inside of the skins. I'll just scotchbrite it off or use lacquer thinner to remove it. I think what everyone is talking about is Corrosion X or similar corrosion proofing for interior parts. I used some on some parts that got on a few exterior pieces. I just cleaned it off before priming and have had no problems. After all the **** that goes on on this list I will deny any of this information and suggest you don't use it without advise from legal counsel.

    Subject: RE: Taildragger
    Carlos, I tried e-mailing this to your address, but it returned. So here it is for all to read... Carlos, I recently finished my HDS taildragger. I did not, however, use the standard bungee cord gear. I fabricated and installed an aluminum spring gear. I don't believe that the main gear installation would be any more difficult to install forward of the spard rather than aft. Due to the curvature of the nose ribs and LE skin, this area is much stronger than aft of the spar, and lends well to gear installation. The tailwheel installation is pretty straightforward. Once you receive the plans from ZAC, you will see that there are basically 2 4130 components to fabricate / purchase from ZAC. I have a plasma cutter and welder, so building the pieces was very easy, probably less than a day of fabrication. If you did not read my post a couple of weeks ago regarding the Matco tailwheel and leaf spring, look into the archives. The price is right, and makes installation a snap. I chose conventional gear because I fly tailwheel aircraft comercially, and simply have an affinity for them. The Zodiac behaves reasonably well, as far as taildraggers go, with the rudder effective enough to handle significant crosswinds. My first high speed taxis and short flights down the runway were in a 15 knot crosswind, and while it was a bit squirley, it was not a problem. Make sure that if you do not have a good amount of tailwheel time, you get some under your belt before test flying your aircraft. Bottom line - taildraggers just look cooler. :) (Opinion - don't start flaming!) http://mcgirt.net/~ars2006/ars2006/Desktop.html R/ Brandon __________________________________________________

    Subject: Re: Landing Lights
    According to the EAA, the minimum equipment rule (91.205) applies to standard category aircraft but not experimental category, so homebuilts aren't required to have strobes for day VFR. However, the homebuilt Operating Limitations require you to comply with this rule for night flight. So if you have strobes they generally have to be on, but if you won't be flying your homebuilt after sunset, you don't need to install strobes, but if your homebuilt was built recently.

    Hi, Brandon Obviously I can't type worth a rat's tail... My address is carlossa52@gmail.com (not "51").* * It seems that the actual construction of the TD option is not a problem. What may end up being a show stopper is (1) insurance, given I have no TD time at this point and (2) getting TD time: the two airports within 30 min driving have no TDs for rental/instruction...
