If you have an oxygen system built in, Halon away. The 'oxygen system' in a commercial airliner is NEVER used in conjunction with cabin smoke/fire. It is for depressurization problems ONLY. In fact, at lower altitudes, cabin air is recirculated through the system. Also, as you can imagine, in case of cabin fires, the last thing you want is to have more oxygen added to the mix. The Halon extinguishers are intended to be used in relatively enclosed areas, with ventilation added as much as possible as soon as the fire has been dealt with. -- Grant Corriveau C-GHTF / HDS / CAM100

    Subject: Fire Extinguishers
    --> Zenith-List message posted by: Derek Mackie <derekmackie@yahoo.ca> Here are the links for the regs for installation in Canada. FAA regs are similar. Amature (Experimental) aircraft must be equipped with a fire extinguisher that complies with them. http://www.tc.gc.ca/aviation/regserv/carac/CARS/html_e/doc/nav-2200.htm (click on the link for chapter 551.400) and: FAA AC 20-42C, http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/1ab39b4ed563b08985256a35006d56af/cf2f4f1406354490862569ad00777471/$FILE/AC20-42C.pdf Cerified light aircraft in Canada are typically delivered with 2B-C extinguishers due to the cost vs Halon. (ie 2B-C and Halon both comply, but Halon can cost 3x as much) Derek Mackie

    Subject: Halon
    --> Zenith-List message posted by: Brandon Tucker <btucke73@yahoo.com> List Halon is much more destructive to the environment than typical refrigerants. If I remember back to my AC&R days, R-111 is the basis for measurement at an ODP (Ozone Depletion Potential) of 1. R-12 (A chlorofluorocarbon) has an ODP of something like 1.7. That is why it has been almost completely phased out by R-134A. Halon has an ODP of 10! Nasty stuff to the Ozone layer. I thought it was already supposed to be phased out - So if you want it, better get it now. You definitely have to shop around for a good chemical extinguisher. One of the websites I referenced in an earlier post listed PKP (purple K powder or Potassium Bicarbonate) as non corrosive. Not true. We used them aboard ship, but never for electrical panels. They are terribly corrosive for wires and connectors. FWIW - My potpourri of useless information Respectfully, Brandon Tucker ---------------------------------

    Subject: Stratus valve guides
    --> Zenith-List message posted by: "Gary K" <flyink@efortress.com> I'm hoping that I could get some help from the Stratus guy's here and Ron from Ram Performance. I wanted to check my valve guides so I pulled a rocker off and took some pictures and posted them on airsoob. Use http://groups.yahoo.com/group/airsoob/files/ and go to Gary K's Pelican or go right to the pictures at http://groups.yahoo.com/group/airsoob/files/Gary%20K%27s%20EA-81%20Pelican/v alve%20guide/ (note wrapped address). I'm assuming that these are the stock pressed-in guides vs. the newer grooved and clipped style. I'd like to take this discussion off-line instead of bothering the list here so I'll collect a few addresses and resend this to a "Stratus group". If you'd like to help out, please respond to me and I'll add to the list. Thanks, Gary Krysztopik Pelican PL w/Stratus EA-81 subaru 97.459% complete Newport, R.I.

    Subject: Halon
    --> Zenith-List message posted by: "Dave Alberti" <daberti@execpc.com> Halon is destructive to ozone, How many fire extinguishers have you popped in the last 10 years! Halon kills fire at the ionization level, you don't have to see it (the fire) just point where it may be and it will knock it dead! It's my extinguisher of choice and in my plane. PPK goes back to the WWII days, It was the only agent capable (then) of extinguishing a magnesium fire, and there was plenty of that in military planes. Dave " Halon is much more destructive to the environment than typical refrigerants. If I remember back to my AC&R days, R-111 is the basis for measurement at an ODP (Ozone Depletion Potential) of 1.

    --> Zenith-List message posted by: ZSMITH3rd@aol.com According to Hollywood (the source of all Truth, un-biased Government-bashing, semi-automatic pistols with 8000 round magazines, and various other techno-feats) all you need to do is just dive for airspeed and put the fire out, like blowing out a candle. (Reference: "The Memphis Belle" ) Can somebody please calculate the speed necessary in a 701? All we need do then is mark it on the ASI with appropriately-colored tape.

It's been a while since I worked on that area but I believe the top longerons come out to be wider than the bottom. You can double check this with the width of the attachments on the horizontal stabilizer... if you built it already. If you interested, I have a site that is a duplicate of my building log.

    Subject: 801 gascolator
    --> Zenith-List message posted by: "Rich" <rbauer@intergate.com> Where are other 801 builders putting the gascolator? According to the plans, it's either on the fierwall wich is higher than the lowest point of the fuselage or under the rear of the front seats, which IS the lowest point of the fuselage. But the plans also have the gascolator in this location sticking way out underneath the belly. I have a center console for the fuel selector & primer line & I would like to put the gascolator inside, center of fuselage, just in front of the control stick (with clearance of course). Has anyone put it on the firewall without water accumulating somewhere else before it? Rich 801

Did you make a forming block smaller than the nose ribs forming block by 3 mm (1/8") all around (to allow for the cork thickness)? Or...? Any other hints and tips would be appreciated. Thanks in advance Carlos CH601-HD Tail feathers done, wing spars done, working on wings.

    Subject: Oil-canning in wings
    Seal-Send-Time: Sun, 27 Jul 2003 19:14:55 -0500 --> Zenith-List message posted by: <PAULROD36@msn.com> After pulling one wing out into the driveway on the work table, the sun's heat clearly indicated that I'm going to have some oil-canning in the top skin. (maybe there's a moral there--about building the wing during the winter) I'm not real keen on flying inside of a kettle drum. Short of putting on a new skin and doing it under a heat lamp, does anybody have any suggestions on avoiding oil-canning in the wing skins? The first two things that came to mind was to build wing lockers in the offending bays, or inserting a vertical piece of styrofoam in there, and somehow gluing it in place. How have other builders dealt with the problem? Paul Rodriguez 601XL, corvair-ed. Left wing buttoned up.

Carlos, I think the rule applies to the HD same as the HDS, so here's my two cents. I made wood formers for each end cap, as you said smaller than the ribs nearest them by a little over the 1/8" and made a strap with tensioning that would hold the shape of the aluminum skin just like a rib inboard of it whilst it was being fitted and clecoed in place. Both ends were done this way and the back sheet was the last to be attached and welded. Pictures of the wooden forms are on the site and the banding straps are seen there also, but one might not be aware of what's going on if you didn't know to look at the back blocks that the bolt tensioners are run thru. You can get a rather precise fit within the cork if you're willing to go after it. The tanks get fitted to the front rib more than a few times to get it just right. Good luck,. Regards Larry C. McFarland - 601hds

Hi Rich, If you are following the plans, there is also those aluminum weldments where the hoses (or lines) from the wing tanks mix together that also has a drain on the bottom. This is the lowest point on the fuel flow, and as long as the drains are put in, you can put the gascolator anywhere since it's only function then is as a strainer. If you aren't using the weldments, then you need to locate some kind of drain, like the gascolator, at the lowest point. Gary L.

    Subject: Re: Scratch built wing tanks
    --> Zenith-List message posted by: Michel Therrien <mtherr@yahoo.com> Made the forming blocs 3/16" less all around except for the rear side which is 20 or 25mm less (to allow for support against Z stiffeners. I assembled the tanks with 3/32 clecoes (not to many of them) and brought that to the weldor. Claude Guilbault is highly reputed in our area for this type of work. In any way, you should ask the weldor how he wants the tanks. Some will want the flange of the end ribs facing outward (like the tanks from ZAC) some inward. They will also give you their preference for material (mine are made with 5052-H34, 0.040"). One thing I did that I would'nt do again is to install a baffle in the middle of the tank.

I don't know if he follows this list, although I imagine he might. He used a new 2-blade Woodcomp in-flight adjustable prop to win the Schneider Cup seaplane race in Italy last month on a Zodiac XL with a Rotax 912S http://www.airplane.cz/web_files/pr/schneider03.htm Chip follows the Matronics Seaplane-list, but I don't know if he follows this list. Since his email is available there, I doubt he'd mind if I copy it here: aircraft@czaw.cz Dan Thilo Kind <thilo.kind@gmx.net> wrote: --> Zenith-List message posted by: "Thilo Kind" Hi folks, thinking about a new propeller for the 601 HDS (with Rotax 912).
