It is also really good you did not damage your self beyound repair. I can understand the desire to aviate and find it difficult to chastise anyone that finds themselves in a place they would rather not be . Have been there, like the day I hit a real southerly front and went from 500ft to 1500 in the bat of an eyelid then lost the same 1000 just as fast. The spare helmet was glued to the cockpit roof . As I was flying directly into the wind I desided to head home , from the time I started the turn to the timr I came out of it I had covered about 1 mile .Arrived back at the airport and had to use full throttle ,stick hard forward just to get to the ground. Good thing some flying savy people were there when I landed. Very short landing roll ,touch ground ,kill the power and stop. The people that watched me come in were there to grab the wings, drape a body across the tail boom and assist me back to the hanger . The tower gave a gusting wind speed of 35 mph when I landed . that is about my stall speed . The game we play can be very unforgiving . Did I learn anything from my experiance, well yes ,just because the weather was really calm when I took off the indications were there that it was going to change, so I should have used my judgment on the weather as opposed to my desire to go flying and I also learned that Kolbs can fly backwards, as I was on short finals and reduced power the runway was getting further away.

Which makes taxiing about as much fun as riding a garden tractor, as it should be. If your instructor didn't explain this to you, give serious thought to finding a new instructor. If he didn't give you explicit instruction when he released you to do slow taxiing, in what else has he been remiss?

I'm a lurker here myself, and it appears Bill S. is not trying to learn how to fly here on the Kolb List, but simply gain helpful advice and ideas. If I had my own Kolb and was just learning how to fly it I would definitely have an instructor to show me the straight and narrow, but even still the wisdom of you all would be very helpful and informative.

Learn to fly with a competent instructor. Get a little air sense. Go thro ugh Ground School. Seems that would be a good thing to do since you are bu sted up at this time, and can probably handle the class room work. Learn t he basic terminology of aviation, aircraft, and flying. That is the normal place to start. After you learn to fly, then you can get familiar with ty pe. Nothing peculiar about Kolbs. They are little conventional three axis cont rolled aircraft. The differences between other models of GA and experiment al/ultralight/SLA aircraft pertain to Kolbs as well. The Kolb List Archives are full of "incidents and mistakes by others", your s included. I think both hand deployed parachute saves are in the archives. If not, I' ll share them with you the first time we meet. I am not trying to be critical of you. I am trying to get you to see "real ity". If I am headed in the wrong direction, let me know and I'll go do my chores. ;-) Gravity is not prejudice. It affects me same as it does you.

I have been reading (and using) about the new Sta-bil. There is a website for it at www.goldeagle.com/sta-bil/stabil_marine.htm. There are also some other brands you can find at marine outlets. I have used stabil forever to keep tractor and motorbikes, generators clean. This is formulated special for ethanol. I had it in my gas the whole time I was flying at the homecoming. It sets my mind at ease that I should not have to worry about corn squeezins in my tanks. Check it out and you may find one less thing to worry about. Oh, yeah, put in my rv too, one once per ten gals of gas and although I did not get better mileage, it did run a whole lot faster over the mountains, has an octane booster in it. I am sold. Had a funtastic time at homecoming. Great to see all you guys again, so many Kolbs, so little time. Was impressed with the Hurth on the MkC. Sounded and performed pretty much as a Rotax but I guess a bunch cheaper. Also was a fantastic plane. Red, White and Blue, my colors. My Kudos to all who worked the homecoming. We appreciate it.

I strongly disagree with the second part of your post, an electric fuel pump should always be on for takeoff and landing. Takeoff is where the fuel demand is the highest, and when you are most likely to need an electric pump. The safest thing you can do is to keep your engine running on takeoff, and prevent a crash period, you will not have time to turn on your fuel pump or restart if your engine quits soon on takeoff. You increase the chances of a crash and the fire you are so worried about by not running a backup fuel pump on takeoff. You obviously saw the results of one accident where a freak set of circumstances made it much worse, but to base your actions on ONE ACCIDENT is bad judgment. Just because something happens ONCE does not make it PROBABLE. I flipped a coin once, and it landed on the edge, does that mean than in a coin toss I am always going to guess the coin will land on the edge ??? No, I will chose heads or tails... I will chose something that is likely, not something that has a one in a million chance just because I have seen it before. Your chances of a crash on takeoff and a post crash fire are increased by NOT running the fuel pump. It is important to look at what the biggest risks are rather than obsessing over what happened in one freak accident. In certified aircraft, the procedure is to have electric backup pumps running for takeoff and landing. The best solution to avoid a fire is to avoid a crash on takeoff, the best way to avoid a crash is to keep your engine running on takeoff.

Since the crop has been picked the field is smooth with rows of peanut hay however its real dry and dusty. I am sure many of you are familiar with peanut fields and how dusty things are during harvest. I would like to use it as my airstrip until the guy plows it in which will be a while probably 4 to 5 months however i am a bit concerned about the dusty conditions damaging my prop and sand blasting the tail section.

I've put a couple hours on her since my last post and noticed these things. Climb out rpm is 5800-6000, level flight is 6200. Prop is 66 inches and 30 degrees pitch. CHT is 260 front, 290 rear. EGT's are good, after dropping my needle, moving around between 900 and 1100 degrees depending on throttle position. I never revisit WOT after climb out, so I was kinda in the dark as to my max RPM at level flight. I throttle back to 4750 RPM and this gives me 'bout 50mph AIS, my comfy cruise speed. I'll give R. Smith a call and see what his take is. My friends at the airpark say leave well enough alone. But I think it has to do with my Kolb embarrassing their planes on climb out. They all are running 503 DC/DI and none are showing CHT below 350. If my Rotax manual didn't say 330 to 425 degrees, I'd be a happy camper. Even if there's a little more power to be had at 6500 rpm. I feel my climb outs are safe. I can hold it at 50 mph and I'm getting up in a hurry. -John Read this topic online here: http://forums.matronics.com/viewtopic.php?p 5466#205466 ________________________________ Message 2 _____________________________________ Time: 05:50:36 AM PST US Subject: Kolb-List: EGT?

Whether they initially hit the treetop at that angle or came in at a normal glide angle and then dropped after hitting the tree I can't say. Engine was [I think] a 912, or perhaps a 914.

I might be crazy but I swear I can tell the difference in smell between the regular and ethanol blended gas. Anyway I know rotax does not recommended ethanol at all over I think 5% and they do allow use of av gas some of the time. I have heard of some people using exclusively 100LL in 2 strokes with no problems. Then I have heard that the lead will flat spot the bearing and cause deposits in cylinder and foul the plugs more often. So far so good with the E fuel but I still don't like it.

Grant R: I used a lot of 100LL during my travels with old Firestar and point ign 447. This was in the 1980's. I doubt there would be any difference now as then. Hope 100LL doesn't flat spot bearings, because I burn an awful lot of it in my 912ULS loaded with bearings. I always ran my two strokes hard, as I do my 4 strokes. I cruised at 5,800 rpm, the recommended cruise power for all the current Rotax two strokes. Sometimes, when I got closer to home after a long trip, I'd push it on up to 6200 rpm and let it rip. I am a firm believer in running the engines as they were designed, not babying them, but keeping them blown out and clean. 4 to 5 thousand rpm hardly keeps a two stroke crankcase free from excess oil. My thoughts only, for what they are worth. john h mkIII ________________________________ Message 9 _____________________________________ Time: 02:00:40 PM PST US Subject: Kolb-List: Re: 100LL use in rotax 503?

Grant R: Probably leaves less carbon deposits, but some lead deposits. Spark plugs are cheap. I would not skimp when it came to changing them out. Usually, you can pull the plugs, use a small pin knife blade and a piece of safety wire to clean the lead out of the plugs. I end up doing that occasionally on the 912ULS on long cross country flights. john h mkIII I don't have a problem babying my 503 on my Mk III she has to turn about 5700 to 6000 to cruise.:D > > Did the spark plug last as long with the 100LL.

My, the years are flying by. Was great to see all my old friends again. Where else can you come together once a year, spend a weekend with folks you met at the Homecoming in previous years, have the same love of the same aircraft, eat enough for two people, go to bed early and get up when you want to, and not spend a dime, except for the money to get there and get back home. Bruce Chaison, James Tripp and I had a good flight to Labhart Field. Even though we had a headwind most of the way, we still had fun and got there in time for the BBQ put on by Bryan Millborn (sp). The "cake lady" had two scrumdiddlyumpscious cakes, just like last year. All the food was great, three meals a day. Entertainment was put on by my main man Travis Brown and his five string banjo. He was accompanied by Eddy and her feller, and Howard Brandon. We were also privileged to hear a little 9 year old girl sing a couple songs for us. The photos are: a.

From: "grantr" Maybe I didn't word that the best. The issue is I bought a new dual EGT gauge and one new sender. I am using the old sender on the pto side and the new one on the mag side. The new sender mag side reading continues to read say around 800 degrees and tapers off gradually over a few mins after engine shutdown. the other sender pto side basically tapers off quickly after engine shutdown. What is the gauge suppose to do normally? Slowly taper off or rather rapidly? The only think I could thing off that would cause this is the sender touching the exhaust pipe wall, however I am 95% sure thats not the case.

However, mine is located (by a previous owner) at the intersection of the two pipes, about 6" from the gasket(s). What I'd like to know is how much does that affect the indicated temperatures? I've jetted to keep the full throttle EGT at or below 1200F (Cuyuna specifies 1200 as "best HP" and 1275 as max), and the plug color seems to confirm I've got it right. When I slightly close the throttle so the needle drops into the jet it rises slightly as I'm told it should, and it runs quite a bit cooler at cruise. CHT is fine too, around 300. Haven't had any engine problems except for the sudden stoppage a few months ago which I now attribute to a bad carb float needle. It's a basic sensor, in the EGT/tach 2" combo gauge. Relocating it is no big deal, but I'd rather not do it until I have the exhaust off for some other reason anyway. -Dana -- Sometimes you're the windshield, sometimes you're the bug. ________________________________ Message 17 ____________________________________ Time: 05:13:04 PM PST US From: herb Subject: Re: Kolb-List: Re: 100LL use in rotax 503?

It had the EGT probe at the "Y" also. I relocated it to 2" from the piston, which may be 1.5" from the exhaust gasket. The temps came down quit a bit. I can't remember how much, but probably 150-200 deg F. The EGT also became much more responsive with power changes, choke, etc. If you haven't already, you definitely need to relocate it. Where it is is better than no EGT, but not by much. Jim D. N.

The other problem with having low WOT RPM is the horsepower loss. The top of the 447's power curve is pretty flat from 6200 to 6600 RPM. At 5800 the engine is down 7 to 10%. That's a pretty good reason for getting the prop set up right, too. Rick On Sun, Sep 28, 2008 at 9:33 PM, Richard Girard wrote: > Gary, Why apologize for doing exactly what Rotax recommends?
