You are a most influential person, Charlie, but I can't help but think that the 9 cyl. was already in the works...regardless I have a engine monitor and it is a most useful diagnostic tool.

Yeah, well, the JPI does this, as do the other systems, BUT, Brian, you're right...why take up HALF MY FRIGGIN' PANEL to give me a bunch of information I don't want to see unless something is wrong, or I specifically want to check something???? My best guess is it comes down to sales...it just looks prettier with all those colors shining at once. Barry

    Subject: EGT / CHT
    --> Yak-List message posted by: "Sam Sax" <cd001633@mindspring.com> Tom, I am running the JPI 700-9C for almost 4 years now. I've also installed the option for the built-in fuel flow - great thing to have. As to the EGT, at least in my engine, they are not uniform. Cylinder #4 shows highest EGT in a given setting in any altitude followed by #3. Typically, coldest are #6 and #7. Interestingly, my hottest CHT cylinders are also #3 & 4. By the way, I did loose a spark plug in flight sometime ago. Its amazing how quickly one can determine the problem (sudden EGT rise in that cylinder), and contain the rate and amplitude of his/her heart beats. Upon landing at the nearest airport, I simply took out the bad one and put in the spare one I had and off I went. Total time lost 30 minutes. Cost - $0.00. Imagine landing in an airport in the boonies asking the "expert" mechanic on duty to trouble shoot your problem (of course, you wouldn't even know it's a spark plug). Time lost - a day or two. Cost - you estimate it... As far as I am concerned, that event alone, paid for the unit.

    Subject: EGT / CHT
    --> Yak-List message posted by: "Roger Doc Kemp" <viperdoc@mindspring.com> It still all comes down to why did the Russians design their steam gage to measure the temp on the #4 cylinder when #9,1, and 2 are the hottest cylinders? There is a such thing as TMI ( To Much Freeking Information). When flying formation you can take a snap shot of the engine instruments under the currant steam gage arrangement (assuming your panel is stock Russian in a 1990 or older A/C). As much as I would like to know what is going on in the other 8 cylinders, all of the existing MFD's provide way to much information for that snap shot, take up to much room in the panel, and cost way to much money. For now I will stay with the round dials and fly fat, dumb, and happy (as long as the big Radial continues to rumble). Besides, I can't richen the mixture to cool the cylinders preferentially anyway with the YAK 52. I guess the Russians felt that as long as the master rod was happy, the rest of the M-14 would be happy. They followed the KISS principle and God what a work horse they put out. Sure am glad we did not have to face them down in the Foulga gap during the Cold War (for us ol' farts that stood on that line). The end may not have been as rosy as our leaders would have lead us to believe. Sometimes simplicity trumps technology particularly when you can produce it in large quantities and make it work under extremely austere conditions! This sucker just keeps on chugging when it is hot as hell or freezing ass cold, what more can I ask for? A new $10,000 panel that has all the colorful bells and whistles that overloads my ol' dumb brain that is totally confusing to me when I try to take a snap shot of the panel while hanging on #2's wing in a 4 ship of a 16 ship mass gaggle while asking myself the whole time why I even considered why I jumped in this goat rope as 2 bobs up & down like a 20 ft boat in 10 ft seas. Yes, that was a run-on sentence. But opinoons are like assholes, everybody has one and guess I just gave mine. For me, I will stay with the KISS principle and baby my M-14 just watching that ol' #4 cylinder hoping that that master rod is happy while #9, #1, and #2 bake. Sorry for my extanious BS I threw in as my personal opinion. Hell its an upcoming holiday weekend and I'm on call sitting here wishing I were flying and at the lake with to much free time for my fingers to do the thinking.

The problem is, fast-response probes are usually more fragile and need to be replaced more often. Insulated probes (needed for cheaper instruments) are slower response.

You get what you pay for. > Of those running the EDM 700-9c: How does mixture (EGT) distribution look? You can't tell mixture distribution unless you have a mixture control so multiple EGTs are not useful for normal operation of an M14-P. The actual EGT value doesn't tell you anything. Hotter does not necessarily mean leaner. The only way to tell mixture distribution with an EGT is to start rich and lean a little bit while watching for each cylinder's EGT to peak. If they all peak and then begin to fall back together (regardless of actual temperature) then the mixture is identical in all cylinders. This is what GAMI does with their customized fuel injectors. They match the fuel to the airflow for each cylinder so that mixture is identical in all cylinders. This allows for lean-of-peak operation which saves a lot of fuel. Lean-of-peak operation used to be normal for the big radials on recip transports. LoP operation results in cooler operation and fewer combustion byproducts in the engine. -- Brian Lloyd 6501 Red Hook Plaza brian-yak@lloyd.com Suite 201 http://www.lloyd.com St. Thomas, VI 00802 +1.340.998.9447 (voice) +1.270.912.0788 (fax) I fly because it releases my mind from the tyranny of petty things . . . - Antoine de Saint-Exupery

For now I will stay with the round dials and fly > fat, dumb, and happy (as long as the big Radial continues to rumble). You are on the right track. You want the information quickly and too much information is not helpful. OTOH, it would be nice if the equipment would tell us there is a problem. It doesn't take a very smart computer to say, "gee, #3 is at 220C and that is too hot." And it may be a mindless idiot but it will never forget to keep checking to see if #3 is at or above 220C even while I am looking out of the cockpit. The biggest thing missing is trend information. Normally we want to see about 160C on the cylinder head temps. But you are flying on your buddy and loosen the friction lock so the shutters close of their own accord (Yak-52, not CJ). The CHT starts to rise. Wouldn't it be nice for your engine monitor to say, "hey, the engine is going to overheat in 30 seconds," rather than, "hey, the engine just overheated." Oil temp and oil pressure trends are even more interesting. A minute's warning of an impending oil pressure or temp problems would be *really* interesting. > quantities and make it work under extremely austere conditions!

Yes, that was a run-on sentence. And you aren't even remotely going to look at the panel in that case. Hell, the only way you will know if you are on fire is if someone says, "Hey 2, you are on fire." And if the engine instrument was *really* doing its job you would never even look at the panel. The engine instrument would tell you when you needed to do something. I actually had an engine monitor that did all this in my RV-4. It took one 3.125" gauge. I had it display RPM, fuel flow, leanest EGT, and hottest CHT, the things I could control. Everything else was on aural alert. If I was doing acro and the engine started to overspeed I would hear, "warning, engine RPM high" in my headphones. (It has a fixed-pitch prop.) If I forgot to switch tanks it would say, "warning, fuel pressure low," long before the engine even hiccuped. I never had to put my head back in the cockpit for anything except for a glance at the ASI while in the pattern or to lean the mixture in cruise.

    Subject: Re: was Yak Air Bottles, now paintball tanks
    --> Yak-List message posted by: fish@aviation-tech.com Yak List, My understanding of paintball is that they use compressed air (from scuba compressor), but do not filter the air. Cheaper and they can fill them themselves (Shops, make more proffit) I found a regulator at my local welding supply that I use on my nitrogen tank to regulate it down to what I want. I also have a regulator on my compressed air tank, making it easier to chare my tank to the right pressure without crawling into the cockpit. But the regulators are expensive ($300-$500 each). The first regulators I purchased would not go high enough, so I had to purchase more expensive regulators. While they are expensive, I am now happy with the results.

Possibly. Barry and I tried to do that about three years back. I think he had one in his Ghirkin. Regardless, we could replicate it. A friend of mine, Matt Dodd, is just about done with the gear warning system for the Yak and CJ. (He lurks here getting ideas for instrumentation from you guys because he is not a pilot yet.) If people like the idea of an engine monitor that takes up no room in the panel and will handle any number of engines and cylinders (think B-17 or B-24 here), we could do that without too much trouble too. > It could easily go in the current CHT hole and really would serve a purpose. Right. It could even be a hidden box with no display at all. You can still keep your steam gauges and yet have all the aural warning stuff. No reason why not. > Now that is something that I could use. Kinda like bitch'n Betty in the > Viper, but... sometimes you really do want to choke the b_ _ _ _ _. Yeah, you need a way to say, "shut the ... up, sweetie." A button on the front or on the throttle would work just fine. > But she will even tell you are on fire with[out] 2 saying a word. Fire detection is possible but hard to do in GA aircraft. It costs money to make it reliable. The hardest part is figuring out where to put the fire sensor (which aren't temperature sensors). > And I agree with you on all the previous I deleted from this message for > the sake of brevity. That is the right answer. So Doc, what would you pay for a "bitchin' betty" aircraft systems monitor? Sure we can make it monitor the engine but what about the electrical system and the pneumatic system too? How about messages like: "generator output low" "air pressure low" "emergency air pressure low" "landing gear" "fuel level left low" or maybe "bingo fuel" in addition to the messages for the engine. -- Brian Lloyd 6501 Red Hook Plaza brian-yak@lloyd.com Suite 201 http://www.lloyd.com St. Thomas, VI 00802 +1.340.998.9447 (voice) +1.270.912.0788 (fax) I fly because it releases my mind from the tyranny of petty things . . . - Antoine de Saint-Exupery
