I have no idea how to check them, but it sounds as if they're maybe bad or shorted. Maybe if you reverse the probes in the exhaust manifold, and see if the same cylinder gives the same indication. If not, it's the probes (or the instrument). If so, the motor is doing it. I'm not convinced the Bing carbs are very accurate metering devices, especially with age. My grey head was odd, as well. Not like yours, but at low throttle, it was close, at WOT, it was mostly within 5-10 of each other (sometimes dead-nuts on), but part throttle was anybody's guess. At least it was consistently odd. Mine did not jump around like you describe, but they would separate, sometimes beyond Rotax limits (at part throttle settings).

By how much? My slides are as level as possible at various throttle positions, yet the rear egt is about 10F-60F warmer, depending on the rpm and if I blink.(so it seems) This is measured with a digital gauge. At one moment it will be with 5F, then with now reason for change it separates to about 50F. Each flight is different. Am I chasseing my tail, or is it an early symptom of a problem? 582 with 130hrs/4yrs - but many short frequent flights. Thanks guys, Larry ________________________________ Message 2 _____________________________________ Time: 06:06:54 AM PST US From: "Larry Martin" Subject: Kitfox-List: Re:582 EGTs --> Kitfox-List message posted by: "Larry Martin" Thanks Bradley, I did switch the probs and the temps followed to that cylinder. Actually, I have one cylinder at ideal temps, and the other is cooler. I'm going to swap carb positions and see if that changes. As I get thinking about it, one carb is older than the other, assuming the jets it larger with age, it may explain the difference in temps, even though the slides are sync'd. Does anyone replace the jets at 150 hrs, as per Rotax mm? Larry Is it possible that your probes are doing it? I have no idea how to check them, but it sounds as if they're maybe bad or shorted.

Which tires are you using? I've got the Carlisle ATV knobbies, at about 3-4 PSI. No bounce at all (at least not the plane's fault ), and I've been told that my bungees are too loose. I disagree, but since I didn't put them on, that may be true. I don't sag at all statically, but my toe-in pulls them out a little when I push back into parking. I have to lift the right wheel and move it in, so it doesn't sit that way overnight. BTW, I've got 5 wraps.

It is just the normal weight. But just to check, here is something I learned from SkyStar while building my S-5: You should be able to raise the elevator to any point, say to a level position, then let the stick go and the elevator should drop all the way to the down stop. It doesnt have to bang down, just get there on its own. If it stops before that, you have too much friction. If you have a friction problem, disconnect the controls and find it. Most likely the elevator hinges will cause this. On the other extreme, you should have no slack either. No movement of the stick without elevator movement and there should be some slight friction to prevent flutter. As long as the controls are tight, but the elevator drops on its own weight to the stop, you are good. If all that is OK, the weight of the elevator itself is no problem in flight and the Fox 7 should feel very nice to you. It will trim right up to hands free. After flying a Cub, a Champ and a Citabria for warmups, I found my S-5 flys embarrasingly well. Kind of like a fighter version of a Cessna 180 with a stick. It felt heavy and stable, yet a flick of the wrist and it would go where I wanted it maybe twice as fast as the Cessna could. I was afraid to say this at first for fear of losing friends with store-bought planes. Now I find they look OK green. :-) Kurt S. --- darinh wrote: > I just connected up my elevator and the stick forces > are quite alarming (heavy)!

On mine, I can lean toward peak with temps increasing at low and high power, but not at mid to high cruise. There I will exceed 1450 EGT even "full rich". I can only lean past peak to lower EGTs in the higher cruise range. There is not enough enrichment before peak available here for me to stay below 1450 on the rich side. I have not been flying lean of peak, but maybe should try it on Rick's advice. I know the engine will run there from my gascolator drain blow-out incident. Lean of peak, I might keep the EGT's down, save some gas and better lubrication too. Then I can use these power settings in flight. I might even hit my goal of 100 knots on 6 GPH or less. But as Rick said, will it be stable enough to use? I'd need to test it to see if I can keep LOP both smooth and cool. So far I have had 4 incidents where I exceeded 1450 to as high as 1600 EGT's in flight. Not for long, but I would rather avoid any more. This is where I wish I had an EGT limit warning system so I can catch it sooner. Kurt S.

I looked and they had very limited cargo space, so I asked. They were there for a whole week from NY. Yes, it only carried 40 lbs, 20 for the camping gear and 10 for each of them. I told the guy that if he has a woman who can camp for a week on 10 lbs, he better keep her! That got a knowing smile from her. Kurt S.

I would strongly suggest reading the article on the avweb web site. Its been awhile but I bet its still there. It's a simple comcept but some how very difficult to explain. Just a couple of quotes I had save ref the subject. LOP is not for full power settings. "The Lyc rep might want to check back with his engineering dept. Their more recent comments have been that properly instrumented a Lycoming engine could be easily and safely run lean of peak. The old standby was always "50 F degrees" whether ROP for high power operation or LOP for reduced power. Actually testing has proven that 50 F ROP is the realm in which detonation is most likely so when running ROP it is safer to be 100-125 F degrees ROP." "Generally, a liquid cooled engine can run 10 to 15% leaner on EGT than an air cooled counterpart. The lower head temperature (200 F. vs. 450 F.) is the main reason. An air cooled engine is limited to approximately 1550 to 1600 F., whereas a liquid engine can go as high as 1725 for short bursts."

Little things like very slightly worn tooling when making the carb, position of the carb on the engine or in the fuselage, slight differences in each side of the engine (a 582 is built sort of like two single piston engines on a single crank), slightly different float heights, etc. Rotax allows for a difference of several degrees between cylinders (it's in the manual somewhere). The differences were so large on the 618 that different jetting was required front to rear. The best way to handle this that I have found is the Arctic Sparrow kit that allows adjustment of the needle height from the cockpit. You can tune your carbs for the heat range you need and balance them in flight. You will not have to compromise on the needle setting. There are kits now on the market that apparently will allow even more control. Maybe that's what you need.

Typically, this condition occurs when insufficient stimulation of this part occurs, or occurs at irregular intervals, such that it's performance degrades over time. While mechanical intervention may be indicated in extreme cases, a simple remedy first to be applied is, to correct the lack/irregularity of use. Reference to the literature indicates that, the active and positive support of one's spouse has a direct and positive effect on outcomes. His recovery may be immeasurably enhanced by your personally encouraging/inviting him to more, and regular use of his flight skills.
