Got a buddy with a beautiful Kolb SlingShot and he is experiencing some hairy problem. Read: SYMPTOMS Loss of power during take-off. Full power is applied at take-off generating 6200-6300 rpm. At approximately 200 ft altitude the rpm begins to drop gradually until it reaches approximately 5000 rpm. When it begins dropping, I will bring the throttle back to around in case the engine is beginning to seize. Even though I should be turning around 5500-5600 rpm at this setting the engine continues to slow until it reaches 5000 rpm. The engine seems to operate normally at throttle positions below where 5000 rpm would typically be. Above this throttle setting has no effect on rpm. Temperatures are in the normal range. The engine is running smoothly. Switching on the electric fuel pump does not have any effect. If I tie the airplane down and run the engine the symptoms do not occur and the engine runs normally. The symptoms during flight are consistent, they happen every flight. CHECKS AND WORK COMPLETED 1. Cleaned air filter. 2. Disassembled and cleaned carburetors. 3. Replaced spark plugs. 4. Pulled and cleaned fuel tanks (I did find a moderate amount of dirt in tanks). 5. Filter all gas before returning to tanks (The gas is fresh). 6. Replaced all fuel lines. 7. Replaced fuel filter. 8. Pulled the cylinders to check for seizure (no evidence was found). The rings were free. 9. Replaced muffler with a known good one. 10. Replaced tube in left tire (what can I say, it was flat). FURTHER CHECKS TO BE COMPLETED 1. Install a fuel pressure gauge at the carburetors to confirm fuel pressure. 2. Go thru the ignition system. (How do I do this?) 3. Replace pulse line. Thanks for any help that you may be able to contribute. Jim Holbrook He lives down in Panama City, Fl, and I am here to tell you, it aint no place to have the engine act up. We gotta help him. All you engineers, soothsayers, knowitalls and high time flyers, HELP. Gotta get this thing fixed. Maybe the electronics are working the advance backwards? You can reply off line or on line whichever. All maybe benefit from this. Mass problem to be solved. Ted Cowan ________________________________ Message 4 _____________________________________ Time: 04:35:53 AM PST US From: Richard Pike Subject: Re: Kolb-List: 582 problems --> Kolb-List message posted by: Richard Pike First question: has it always done this, or is this something new? If it has always done this, I can only think of two reasons: 1) prop load changes due to airspeed. 2) air pressure on the carburetors/fuel system changes due to airspeed. So - Try taking some pitch out of the prop and let it wind up a bit tighter static. Possibly you have so much pitch in the prop that it is stalled static, and the 6300 rpm static does not reflect what flight loadings would be. As you increase airspeed, the prop unstalls and begins to bite, and loads itself down so that 5,000 rpm is all the engine will pull. If someone else on the field has the same prop/ engine/ gearbox combination, compare your prop pitch to theirs. Caution: if you prop for too high an RPM static, the prop can sometimes unload so much at cruise that your EGT's will go higher than normal. Here is another one to look at - The little tubes that run under the carbs, from one side of the carb to the other, do they have 4 holes in them, located perpendicular to each other? Or are they located in an area where in-flight air pressure or suction could occur? As the RPM's begin to fall, what does the EGT do? And what kind of engine is it? And how many hours? Prop? Gearbox ratio? I like your idea of a fuel pressure check. Good idea. Richard Pike MKIII N420P (420ldPoops) tc1917 wrote: > --> Kolb-List message posted by: "tc1917" > > Okay gang.

The coils can pull right out, along the axis of the thing. And another thing - Make sure that nearby airplanes, also tied down, can't blow into yours. You might need to retie them yourself....

And fellow Kolbers, I am so excited to see the posts of the GREAT Arty Trost (WanderingWench----and she is!). It was a great pleasure to meet and then get to know this charismatic and fun little gal during the MV get together. She is very open and fun to be around and what a pilot!!!!!!!!She flies a Maxair Drifter pusher, which is an updated version of the original 1970's circa Hummer designed by the late Clause Hill. The Hummer in my opinion is the best little ultralight back in the 70's and even today (old poops may attest to that). It is the first plane that had me dream'n as a young lad of building and flying my own plane. Because of its great pilot view from the pusher configuration, it made me want a Kolb with the same great view. Uncle Craig owned and flew the one that conjured dreams of flight in my head. (Wench- we just found old pictures of him and his Hummer-trailer and flying the hummer....we will post them soon). The wench flies her Drifter with just a small nose pod to cover her feet and mainly hold instruments. She has a windshield---the size of a post card. Arty- I could just imagine seeing you holding your arm over your face to keep the rain from pelting you. What a pioneer for women ultalight aviation, and a inspiration for all of us hesitant to wonder out of our back yard. She basically flew the whole southwest on the end of a broom stick!!! It is a treat for all of us to have her on our list. Her husband has nothing to do with aviation, but like a true companion lets the wench's leash out so she can pursue her love, and give us a chance to meet a very endearing lady. Arty, great post on the tail wheel, and welcome, welcome, welcome to the Kolb list.

Hart" Subject: Kolb-List: Wilbur Wright's Birthplace --> Kolb-List message posted by: "Jack B. Hart" Kolbers, You never know what is going to happen to you or what you will find when you move to a different state. It just about 35 miles southwest of I22 is located the birthplace of Wilbur Wright. Today they had a festival there, that included old tractors, automobiles, flying model aircraft, parachute jumpers, line dancing, clogging, food and free museum tours. They asked if EAA Chapter 373 would put up a display, and if they would fly in some planes to land on the RC field. I offered to fly the FireFly. No problems landing. Talked to hundreds of people and kids about ultralight vehicles. Then came the moment to fly off a very short field. The air temperature was over 90 degrees. I angled to give me maximum distance into the wind and where the field ended in a rather sharp incline. I figured it the FireFly would not break ground the rise would throw it into the air. Fortunately, the FireFly broke loose just before the incline and flew up over it. Air temperature at 2,500 feet asl was 80+ degrees. A real banner of a day. If I do this again, I will strip the FireFly down and send my luggage compartments and gear, and my avionics vest (ten pounds) home in the trunk of my wife's car. Also, I will start out with no more than 3.5 gallons of gas. The next time I practice short field takeoffs from grass, I do them in the heat of the day. Jack B.

We also have J for Jane which is a Lanc which cannot fly as she needs a new main spar (1 Million pounds sterling) but does taxi runs . I managed to get on one of those a couple of years ago. In fact it isn`t so much a `run` as a creep but being inside the fuselage with those four Merlins roaring just feet away is certainly thrilling. Forgive the non Kolb post but I think most flyers are interested in flying generally, not just what pertains to their own type of machine.

One time I found some at a Northern Tool outlet store in the RV recreation equipment section that were not staked. That made them a little stronger and don't twist off as easy. Having looked at how the Claw works, I still think it the best solution but a little heavier including the hammer. Anybody weigh 3 of the dog stakes. jerb At 04:13 PM 6/15/2006, you wrote: >--> Kolb-List message posted by: "planecrazzzy" > >Hey Jack, > You gave me an idea on those Dog tie downs... > > I think I'll cut it like you did....then heat it and make a loop > and weld it. > > I'll have to screw'em down with a straight bar....but it should make'm > >lighter and smaller....

I will run ethanol in my Suzuki conversion as soon as I have it running All the articles I have read so far say nothing about the Ethanol itself. They talk about the effects or speculated effects of the Ethanol on old rubber parts. I don't know of any modern seals that deteriorate because of ethanol. Heck we drink the stuff, we call it Vodka sans the 15% mogas. In all respects Ethanol is a better avefuel than the expensive stuff we burn now. As we have not heard of any crushes attributed to E-85 I can safely say that its looking pretty good. For sure somebody is flying with it already.

I can't put it directly into the tank, but I can buy a can of gas and put it in at home. Lobby your state to keep ethanol out of high test gas. Most people by the cheapest grade, anyway, so that's where we get the most bang for the buck, so to speak.
