Situation, 3 years ago, I've bought a KX-125 and used it in my Star. From Day one on the VOR part was not working (couldn't get a signal strong enough) as testing took a year with two configuration to test plus noise measurement etc. I did not spend much attention (I know I should because of guarantee) on that until last spring. A test showed immediately, that the VOR Receiver must be bad. As policy does not allow to repair outside factory we had to send it back, took more then 3 month with several quotes raising the estimated repair cost from about 600$ to meanwhile 1264$ plus tax and shipping (the Com being also defect). I think this is a bit of a rip off, as a re conditioned one goes in the rang of 1700/1800$ most. Any similar experience? br Werner ________________________________ Message 3 _____________________________________ Time: 07:49:08 AM PST US From: "Eric M.

But you do have me revisiting the layout of that system... Snip Plus, I made a duplicate cabin heat box and door from stainless, and used a steel hinge for the door. I dodged that task and sprang for the prebuilt SS unit. I also used Bob's SS shower grab bar idea for wire / cable penetrations. I'm very happy with the results. The one addition I made to the concept on my -8, for what it's worth, was to use a length of 3/4 aluminum tube I had laying around as a conduit along the R/H sidewall of the fwd baggage compartment, between the firewall and the gear tower. It runs just below the longeron. The only drawback was that by the time I had run all my sensor wires, MP tube, and Stby alt wiring, I was wishing I had gotten some 1 inch tube for the installation. While I'm at it, what are you guys using for FWF manifold pressure line, and are you running it all the way to the instrument, or making a transition of some sort at the firewall? I thought I had mine all mapped out,, but have heard some dissension lately (off list ) that has got me rethinking it.

The Exitair may be an adequate device to use for escape if you're already on the deck. A better choice to carry in the cockpit may be a hood that does filter CO, such as the Evac-U8. Combined with an in-flight CO detector, a CO-filtering hood could provide the necessary time to land the aircraft from altitude if CO is detected, or there is smoke or a fire. Yes, the Evac-U8 and similar are more expensive and take up more space, but.... Would be very interested to know more about firewall alternatives, can you point us in the right direction?

Bob Nuckolls said: " Yup. At Cessna (1965) and every job I've had since, they are referred to as a "bus". Folks often forget to take the second "s" off when paring down from plural busses to a singular bus. Further, the brand name Bussmann and their foreshortening of the trade name for other marketing names (Buss-Power, has been cited as a strong influence for misspelling the word as well. A Google search on "power distribution buss" yielded 67 hits. A search on "power distribution bus" yielded 1020 hits. Bob . . ." I'm afraid I must gently agree with 'Old Bob'. Here in Canada we (who aren't taught by USTV) have learned to respect the source of our language (English) by maintaining traditional spelling - very few of us apparently. Like Old Bob, I was taught by aviation teachers who spelt it BUSS to diffrerentiate it from BUS (Omnibus). "Buses" is thus the 'common' pleural of 'buse' and we all know where that leads. What ever happened to the grammatical rule that a double consonant renders the previous vowel - short or am I all alone here? Referring to Google for spelling is like asking Elmer Fudd to sign up for Astronautical Physics. It simply refers to 'common usage' - the sole quality being most common.

My "authority" on the subject is only that I recently finished listening to a lecture course from The Teaching Company called "A History of the English Language", which doesn't exactly make me an expert. First, the English language, like most languages, evolves. The reason that "knight" is spelled that way is that that way most closely resembles how it was pronounced, long ago. Second, there are many dialects or versions of English. The way someone from Liverpool uses the language is not "better" or "worse" than the way someone from Dallas or Sydney or Vancouver or Cape Town or Boston uses it - just different. And third, a dictionary, by design, presents common usage, which is determined by studying how people are currently using the language. I would expect that a dictionary written in Canada to be different from one written in the U.S. They would have a different "color", so to speak. So please don't assume or imply or say that if it's not the King's English, it's not the English language. If you want a static (defined, non-evolving, dead) language, try Latin. As for how to spell "bus", how does it matter? Terry Do not archive << I'm afraid I must gently agree with 'Old Bob'.

I used to be very pedantic about how people used English, particularly in written form. Then, when I moved to Switzerland and had to "quickly" learn to read, write, and speak German and French, I became *very* tolerant of other people's mistakes in English. I'm still butchering German and French, and in the process, my English is getting worse! The CEO of ABB once said that the company's official language is "Bad English", in order to put non-native English speakers at ease for not speaking or writing perfect English. This was a good move, IMHO. I think we should do whatever we can to help people feel comfortable asking questions and providing answers on these lists. Having had the privilege of working with smart people from all over the world, I can assure you that we have a lot to learn from many people that don't speak or write perfect English, or in probably more cases, any English at all! I know you were just poking a little fun at those of use who are "spell check challenged" - and I promise I'll try to do better. :-) Cheers!

Jones" Subject: AeroElectric-List: RE: Off the topic - Buss --> AeroElectric-List message posted by: "Eric M. Jones" There exists an entire internet peopled by misspellers, and occasionally I venture into it by mistake. It's always certain you are in the Land-of-People-Who-Can't-Spell when Google returns three or four hits. In fact there is an entire AereElectic list run by people who can't spell; their main Guru is Bob Knuckles who proposed the E-Buss and seems to like Crow Bears. It's kind of like an alternate reality. What the real Bob N. said about Bussman fuses influencing the spelling of Bus/Buss seems to agree with my experience. One might add that I was 50 before I learned to spell Littelfuse instead of Littlefuse. I wonder how much business it cost the Littelfuse people? By the Way--They know this and own the sites Littelfuse.com AND Littlefuse.com. They both go to the same site. Google finds ~400,000 Littelfuses and ~40,000 Littlefuses. But seriously, the main problem with spelling is that it makes it hard to look things up in archives later on. I used to read the pertinent US patents in the medical business and one day I learned of an important one that I had somehow missed. The reason was that the device name was badly misspelled on the patent, and nobody involved in the process seemed to take notice. I began to suspect that there might be a world of misspelled stuff out there. How would one ever know? You can write the HTML code to get search engines to go to your website, EVEN if the search string is misspelled, by adding misspelled variants to your metatags.

We've been working with several local companies similar to C/s Solutions recently and have been able to realize significant gains to the bottom line. We're finding that with the reduction in operating expenses coupled with accelerating sales cycles, enhancements to the qualifying process, ability to reach more people and drastic reduction of support call volumes and call times all add up to measurable and sustainable gains. We would like to put a call together where we can better understand your initiatives and potentially align them with our services. At this point we don't know if you folks will be able to realize the types of gains that others are enjoying but with a quick 5 minute call we can make this determination. I'll be reaching out to you early next week. If this is inconvenient for you, please respond and suggest a time and date that is more suitable with your calendar.

I just ran a piece of auto style vacuum hose from the T fitting that collected the primer lines on the engine to a steel fitting on the firewall, then on to the MAP sensor (EIS4000). A short section of 1/8" copper tubing from the T provides a place to attach the hose at the engine end, and another short piece at the firewall side. http://websites.expercraft.com/n51pw/images/117969595342a106f8d3529.jpg In the foto, you can (barely) see the fitting where the line is connected directly under #4 cylinder, passes behind the exhaust tube and in front of the engine mount web, down the mount tube and into the short copper line at the steel fitting through the firewall just under the outer end of the oil cooler. Other than being pretty easy, I'd theorize that the MAP sensor is being fed the average MP from the 3 cylinders it's connected to as opposed to just one (typically #3) and possibly results in a smoother pressure gradient at the sensor, FWIMBW....

I think the connector on the back of your indicator is a Positronics GAP series connector. You can get the catalog at: http://www.connectpositronic.com/pdf/StdDensityRect_C009RevB.pdf Look thorough this document and see if dimensions for a 41 pin device matches your indicator. Now the hard part. It's hard to find tools (and even perhaps pins) for a one-of-a-kind project. Avionics shops stock all then necessary tools and pins for these popular connectors. However, Positronic doesn't sell through dealers. You can probably get them to sample you enough pins for a one-of project but you still need a crimp tool. I think you can use the RCT-3 tool from B&C by removing the pin positioner for d-subs and manually positioning the pin in the tool. You might see if an avionics shop would sell you 41 pieces of 22AWG wire with pins installed. You can insert them without a tool and won't need to extract them if you're careful with the wiring job.
