Our British friends lost their Shillings, the French, their Francs, the weatherman talks now about hectoPascals and winds in meter/second. But the knot, being a nautical mile per hour, is also a minute of latitude per hour. Hence its handy function as maps are still in latitude, longitude. If we change that, we may as well change our 60 minutes in a degree and 360 degrees in a circle. Which, incidentally we adopted from the Babylonians (today, the Iraqui) who made the degree the Right Ascension (the displacement of the sun in relation to the background stars, per day). Meanwhile, the French revolution tried to adopt the 400 degrees circle and Paris as the prime meridian. But ... old habits are hard to die.

I don't remember you saying what happened when the valve went. In flight? New engine? That bad? Response Yes, on take off about 150 feet, valve went. Do not run at 1600, IMHO. I would show you pictures but no sense making you sick. Building new engine and even though it is not directly NSIs fault, they have been very helpful. My new heads have SS valves and the valves are ceramic coated. If you get yours done have the combustion chamber done as well before the valve job. Rick If I remember correctly, Lance said that the valves should be good to around 1600 and the heads over 1700 before cracking. He thinks we are running them too hot and don't know it. He is really against turning the fuel pump off. But he really liked the SS valve idea.

Since the Babylonians, Lowell, it has been logical to measure distances in degrees of the circle since you can directly translate an elevation (e.g. the Northern Star) to a line of position. When we do modern astro-navigation, we still have to translate this into a distance. That's why airmen, who were still using the bubble sextant in the 50s and early 60s, used Mercator projection maps. But those have progressive scales, i.e. it varies with latitude. The navigator then uses the latitude scale closest to his latitude to measure distances. Hence the use of the nautical mile. In Norway, or elsewhere on earth, except the equator, as you say, to translate to a longitude, you have to multiply by the cosine of the latitude. Here where I live, near Oslo, it is quite convenient because the cosine of 60 degrees (my latitude) is 0.5 and the minute of longitude is exactly half a nautical mile.

In those days, they were sailing the Atlantic across "their" islands, Acores, Cape Verde, Canaries and Madeira.

I've been flying my kitfox 3/582 for about 50 hours now since i've owned it....and haven't really run into any problems. I've started to try to fine tune things a little bit...I'm just wondering what other airframes...2's or 3's are normally cruising at....a normal (no wind) grounspeed is what i'm really looking for. I've been changing around the pitch on my GSC to experiment. I just brought the pitch all the way up to about 19 degrees, which i thought would be a little too aggressive....but it seems like it really didn't lower the takeoff performance which has been awesome and i can still acheive high RPM level. It seems like this kitfox handles best at around 65-70 mph cruise. It will definitely go faster, but i'm not really sold on the flapperon trim system. It seems like if i'm going faster, i'm needing forward stick to hold level (adding flaps seems like it also adds lift and requires more forward pitch to compenste..which i see as a dog chasing his tail )and then i can notice the difference in RPM and CHT rise and the ride is rougher. I've been flying around with my baggage pod on during all this so i'll have to take it off to get some real #'s to see how my speed compares. I think the plane is running pretty standard temps and speeds with the exception of my fiddling with the pitch and bag pod, i just was curious what setup others are using with the same airframe/gsc prop/ and 582 engine. That said...if you have a 582 powered Kitfox 2 or 3 with the GSC prop...will you report the following. (Normal Cruise RPM) at (what pitch) resulting in (what grounspeed, no wind) at (what CHT) Just thought i'd see how i'm comparing and maybe make some changes if i hear something i like better...

WAS: Important approach distance? --> Kitfox-List message posted by: "jeff.hays@aselia.com" You can increase sink two ways in a Kitfox slip: Aim the nose down and go fast, or pull back and slow down. I can do very steep slips with slow speed in mine. I practiced at altitude doing a power off slip, and pulling back until the onset of a stall. In my plane the airflow buffets the heck out of the turtledeck (built in cross control stall warning). Relaxing the controls immediately brings the plane out of the buffeting. Having an AOA system is again, very usefull. Original Message: ----------------- From: Michel Verheughe michel@online.no Subject: Kitfox-List: Side-slip technique.

It is here to stay (complemented soon by the European Galileo satellites) and old navigation stuff will only be rambling from old farts like me and Scott. :-) Jeff, as a sailor, I'd be very pleased to use only the Beaufort scale. It uses observation to evaluate the strenght of the wind. On the five boats I have owned in my life, I never had a wind measuring instrument. Instead, I use my "simplified Beaufort scale," which is: The wind is 1) not enough 2) enough or 3) too much! :-) Cheers, Michel do not archive ________________________________ Message 23 ____________________________________ Time: 12:29:43 PM PST US From: "Harris, Robert" Subject: RE: Kitfox-List: Setup comparison..mod3/582/gsc --> Kitfox-List message posted by: "Harris, Robert" Dan what is your 582 water temp in Ferinheit? Mine was getting up to 180 degrees but it was 100 degrees outside. I hope I can cool this thing down more. I was burning 100LL aviation fuel and was told by some that it should run cooler with this and other say it will run hotter with 100ll. Do you know anything about this? I have a kitfox 2/582 bluehead and the maneuver speed is 75 and cruise speed is 85 MPH with an inflight adustible IVHO prop. I have not played with the prop yet because I'm still learning to fly the plane. I just set it to 6200 static RPM on the ground and leave it for now.

It seems like this kitfox handles best at around 65-70 mph cruise. It will definitely go faster, but i'm not really sold on the flapperon trim system. It seems like if i'm going faster, i'm needing forward stick to hold level (adding flaps seems like it also adds lift and requires more forward pitch to compenste..which i see as a dog chasing his tail )and then i can notice the difference in RPM and CHT rise and the ride is rougher. I've been flying around with my baggage pod on during all this so i'll have to take it off to get some real #'s to see how my speed compares. I think the plane is running pretty standard temps and speeds with the exception of my fiddling with the pitch and bag pod, i just was curious what setup others are using with the same airframe/gsc prop/ and 582 engine. That said...if you have a 582 powered Kitfox 2 or 3 with the GSC prop...will you report the following. (Normal Cruise RPM) at (what pitch) resulting in (what grounspeed, no wind) at (what CHT) Just thought i'd see how i'm comparing and maybe make some changes if i hear something i like better... Thanks, Dan Johnson.

Hello Dan. I too have a Kitfox 3 with a 582, GSC prop, about 50 hours experience with no previous one, except my training in a Sky Arrow. I can't give you very accurate figures because when I fly I have either a talkative passenger, a bumpy ride or simply ... I am not good at keeping records. But, in general, I fly at around 5,600 RPM, which gives me about 80 MPH. I have measured my GSC pitch to be 14 degrees at 75% of the radius. I don't have a CHT and I can't give you a figure there. Only a dual EGT that stays under 1,200 F. Water temps varies from summer to winter, of course, but is seldom over 160 F, except on extended climb on a hot day. My flaps are limited to max 10 degrees. I never use them because I haven't been yet on a long flight in smooth air. Each time I fly to another place, it is during mid-day and thermal parcels keep me working the stick all the time. Sometimes I take a passenger for a short trip, before sunset, when it is smooth and comfortable, but then, no time for trimming my pitch with the flaperons. But I have tried it, of course. And yes, it increases the lift. You can feel it by the drop down as you remove it. It also pitches the nose down and I see how I could use it to keep me from a stick pressure on long distance. But it hasn't happened yet. Monday, I flew about one hour to the nearby Notodden ENNO airfield with my son. The sun is still low over Norway but it was enough heat generated to see me going up over 1,000 fpm in the thermals. If I want then to keep level, I need to reduce the throttle and nose down. But then I see that my mixture gets lean and the EGT goes up. The ASI goes up and down and it's difficult to get an average reading. Sometimes a wing is lifted. That's when the glider pilot decide to turn into the "elevator." I tried once but was out of it pretty soon. Glider pilots know where to pick their "elevators."

I listen with interest when I hear list members canning the use of flaps as I find them a great tool in my particular applications. I also use the flap trim continuously to modify not only the stock pressure but also the attitude in flight. I have found that by trimming a little nose down at speeds above 85mph speed increases and fuel consumption is reduced by up to 2 Ltr/hr. (I have the Mizer flow meter so I see immediate responses in fuel consumption to throttle settings and drag). When flying on floats flaps reduce the take of run by a significant amount and when landing the flaps give you a great "nose down" attitude that gives a panoramic view of the landing site without any build of speed. My EGT's tend to be lower in flight than most as I fly with a more aggressive pitch due to the IFA IVO - I could probably address this with even leaner main jet settings but just haven't got around to it.

Thanks for your answer, Jeff, but I am still uncertain: If I want to side-slip and descend faster, do I have to fly faster or slower? At the moment, I keep 65-70 MPH.

When I slip I use 60mph to give me good safety margin above stall - then I can hold a high drag angle of attack combined with a severe bank which gives lots of side area as drag. When you get this right the Kitfox comes down like an elevator and when you are over the strip you just kick in some rudder, straighten up and your normal rate of descent is re-established.

This has very little to do with the prop. The harmonic vibrations are a secondary vibration that occurs (normally in the higher rev ranges) and are background vibrations that are pretty hard to detect. What happens is the spool and the lead screw in the Pitch Motor vibrate and become damaged. The small electric motor also becomes damaged and loses power. The first signs of a problem are the prop won't "pitch up" in flight especially if the prop is under load as in a climb out. Once the load is reduced it works fine. After a while it just stops working. I found this normally happened at about 100 intervals and in each case IVO replaced the assy. Even though the kept replacing the unit at no charge it becomes a pain waiting for the parts and paying the freight so I finally suggested that we find the root cause and they questioned me and determine I had the 3:1/C Box combination. They gave me a full credit on the prop and exchanged it for the much larger two bladed medium prop and I have had no further problems in 140 hrs of flying wheels/skis and floats. Re normal engine vibration: I have set my throttle so that fully closed it will idle down (very roughly) to 2000 rpm but I always keep the throttle partially open to hold about 2800rpm when I land or idle the engine on warm up etc. I kept the lower setting available to me for short field landings but even then as the plane is moving forward there is far less vibration. Two stroke engines and cranks don't like low frequency vibration.

As a gadget guy, I like the old stuff as well as the new. The old stuff really has character. (If they could only speak...) I learned navigation as a young(er) man using vernier transits and theodolites. Most with inverted image (up side down) That is the price we pay for advanced technology. This is indicative of some of the past comments on this list. People get "lazy" when they depend upon tech without a basic understanding of the principals involved. Why would anybody bother with how to read an ephemeris, operate a sextant, plot an accurate course when all you need do (now) is push a button and the answer is immediately there, plotted on a moving map display. What I think is important to this group or anybody really is that (as far as pertaining to operating an aircraft), it behooves us to understand and to be proficient using the "old fashioned" navigation techniques and devices when the tech fails, as it will. I know many that use their GPS as the primary navigation instrument. This can lead one into adopting "sloppy" habits like not paying attention to the "other" instruments. Comments like " I trust the GPS ground speed over IAS" only reinforces that premise. Having said that, I should confess that I have one KX135 radio/gps in my panel, one iQue GPS with Hanger B-17 EFIS on my glare shield, and my handy, dandy Magellan hand-held as a back-up to the back-up. So don't get me wrong, I'm no snob to the technology. But, I'd like to think that I didn't waste my time and money learning to navigate the "old fashioned" way. Speaking of "Old Fashioned", I really like that "natural" you got goin' on in that (was that the 60' or 70's?) sailboat/sextant picture, DUDE!!. :-) I start my annual condition inspection Friday so I will soon be up and enjoying the spring tundra within a week or so (I hope).

I have followed some of the notes here on the site though and can point out that changing the antifreeze/water ratio can help and there are some additives that can do the job too. My plane has a small heater installed and i think i may have turned it on once or twice in the past to be sure the temp wouldn't go to high. I believe mine would probably run close to that in the same weather conditions...i think 180 is the red line marked my coolant temp gauge. I haven't tried burning any aviation fuel yet....does it seem to work well, no fouling problems really? Sorry i don't have lots more info...i haven't owned this thing long enough to wipe off the smile yet. Dan Johnson.
