Users of the system will have to switch to emergency beacons operating at 406 MHz, which are more reliable and provide search and rescue agencies complete information that they need to do their job, in order to be detected by satellites. Reasons for the Cospas-Sarsat program to discontinue use is driven by guidance from the International Maritime Organization (IMO) and the International Civil Aviation Organization (ICAO). These two agencies are responsible for regulating the safety of ships and aircraft on international transits and handle international standards for maritime and aeronautical search and rescue missions. In addition, 121.5 MHz false alerts inundate search and rescue resources which impact the effectiveness of lifesaving services. --- Altho this doesn't bode well, I sure hope they provide some sort of grandfather clause, and continue monitoring the 121 ELT, perhaps just domestically. Otherwise, there gonna be lots of flyers putting out big $$ for the 406 units. __________________________________ http://travel.yahoo.com/p-travelguide ________________________________ Message 2 _____________________________________ Time: 04:49:06 AM PST US From: "Brad Cohen" Subject: Zenith-List: 601 engines..... Seal-Send-Time: Mon, 18 Apr 2005 07:44:49 -0400 --> Zenith-List message posted by: "Brad Cohen" Don, I understand your position about what engine to hang on your plane. I have been trying to figure that out as well, ever since I bought the kit. A few things I might suggest to you in regards to auto engine vs. certificated engines.... But as a disclaimer I have not yet hung an engine on my plane and what follows is just an opinion, and we all know the value of opinions.... any auto conversion that you hang on your plane is going to be heavy. not only the block itself which may weigh much less than, say an O-235, but remember you will have to hang a radiator, fluids, hoses, and all the other accessories to make it run. In my research, the finished, installed weights were actually about the same. There are lots of subaru engines out there, not only in ZAC planes, but also in RV's etc, you might be able to find an RV pilot who can give you some more specifics. I did get a chance to talk to a subaru-powered 601 pilot @ sun and fun who said he was having cooling issues, but remember, that was one pilot and one plane. Of course, there is the corvair engine (www.flycorvair.com); I have not come across any ZAC plane with VW's or 1/2 VW's The Rotax's seem to be getting pretty good press, (www.kodiakbs.com) and maybe someone with a rotax 601 can chime in about his/her experience. There is a new 110hp engine out of Australia called the Jabiru 3300, and if you watch the 601 demo clip on the website, I believe it has the Jabiru installed (it has the cowling air intakes on the eyebrows)(http://www.usjabiru.com/aircraft_engines.htm) After all my research, talking to builders, even chatted with one of the Heintz's I have decided to put one of the "antique" lycomings in my plane for the following reasons; 1. they may be old but they are a proven powerplant with a good track record. 2. parts are easily/readily avaliable 3. simple to work on 4. as a friend told me "they are practically bullet-proof" as a point of reference; an O-235-F produces 125hp and has a dry weight of 249-251 pounds with a 2400 hr TBO. Good luck choosing your engine, I hope my opinion helped and didn't muddy the waters too much for you....

I found it necessary to think two or three moves ahead before drilling any holes. Unfortunately you can't always do that, but in most cases you can plan everything out and see trouble coming. I've had to make all of my parts from scratch so I always question the dimensions before making a part. ZAC has changed so many things in the two years since I started that I now have to check four or five update lists before making a part. Fortunately I've just about used up all of my drawings and I'm on my own now. Get some of those long, deep vice grips in various sizes (Like these http://www.cooknwithgas.com/5_05_03_Clamps.jpg) and try to clamp as much together as possible before drilling and you will see where problems may arise. One day soon you will be clamping that horiz. Stab to your fuselage and get a big grin when it fits right in to place.

I enjoyed meeting some of you guys. Next year I will be there camping for a full week. Anyway, I found something I must have, not saying now, so don't ask. But, I must sell to buy. I am selling my complete Subaru engine package. The price will be reasonable, not a steal but a deal. See all the details at my new page. www.angelfire.com/un/ch701/forsale.html.

More than 1/3 of the rivets wouldn't pass a QA test (good info on rivetting, standards: http://www.rvproject.com/MIL-R-47196A_MI.pdf, http://www.rvproject.com/rivets.html ) Many people had good results with it, I probably just didn't do it right: there are a few precautions you should take (stabilize the spar with sand bags and such). Here you can find some picture and text on the subject: (click "misc stuff" at the top, then scroll to the bottom and look for "Spar".) http://sonex260.wheelsup.org/ I have now decided to go with a rivet squeezer, borrowed from an friend who is building an RV. (Note - Matronics does not allow for file attachments or pictures, which may explain the stream of characters at the bottom of your posting.)

And there is no way that I can see to "adjust" the attachment of 6t2-1 and 6t2-2 without violating the 10mm edge rule. The best edge distance I can manage is only 4-5mm which is not enough. Travis SAYS its no big deal, that the 219 will work fine as long as I specify that I need an HD fuselage which has the correct spacing of 6b3-3 and 6b3-4. Oh well, hard lesson learned. Take home message for those of you who have not started on your stab yet, be sure you know which spar you have (219 vs 233) Brad COhen 5803 N969BC ________________________________ Message 7 _____________________________________ Time: 06:55:19 PM PST US From: Don Mountain Subject: Re: Zenith-List: ELTs in the future --> Zenith-List message posted by: Don Mountain Are any of these new 408 MHz ELT's available now?

I'm building from plan and I was thinking of using integral tank instead , for saving money and getting more fuel 2 or 3 gal hope fully in with the same place.

Every seam and every rivet has to be sealed. The sealant he used was very expensive; $80/pint if I remember correctly. Even after taking extreme care (and making a mess with the goop), he still fought small leaks for a long time. I think having a fuel cell within the wing is the way to go.

This is how they did it: "There is no change to location of the inboard ribs, the nose rib across from rear rib 6 is moved outboard to rib station 1750, we add an extra nose rib in line with rear rib #7.
