Subject: Easy Lat Longs
If you want a quick and easy source for lat longs anywhere in the country, I picked up a program at OfficeMax last week called Precision Street Maps USA, the company is Swift Platinum. You can go to anywhere in the country, and if there is a street there, when you drag the mouse cursor across it, the lat longs read out in the lower right corner of the screen. If there are no streets, then you set the options up to show lat long grids right on the screen, and it then gives you a continuous readout of the cursor's position. Best of all, this puppy only cost $4.99, runs off the CD, and uses less than 2 meg of hard drive space. A good resource for programming the GPS in the comfort of your own home... It does not work outside the lower 48. Richard Pike MKIII N420P (42OldPoops) ________________________________________________________________________________

Found a website that will do essentially the same thing as your $50 CD. Enter town, street-address, zipcode or airport designator and it will give you lat/long. Haven't found a function for lat/long search out in the countryside away from towns, but if you know a small town nearby, should get you close enough for GPS use. Best of all, it's FREE.

The new ones were oval shaped and the old ones were almost rectangular but I figured fresh new ones were better than those old ones regardless of the shape. WRONG ! During my test flight the engine noise was up about 50%. I have always wondered why the price for these things varied so much. I called Comtronics and the nice lady said she will send me some exact replacements for about $12 + mail cost. If I fly again before they get here I will use ear plugs in addition to the head set.

Larry, how much per gallon costs the Amsoil?? Howard Shackleford FS I SC The Amzoil 100:1 is $7.60 retail per quart--the 50:1 is $8.35 per quart, injector oil is $4.45 per quart. I bought 4 gallons for $110 and signed up for a 6 month dealership which meant a discount for me--this is a multilevel marketing system--everybody makes money off the sale. It is not cheap but it burns clean and a little bit cooler than others. On another note--I was at the local Honda / Skidoo dealer and noticed a premixed coolant for rotax snowmobile engines. It said silacate free and distilled water mix--I imagine it is the right amount for their liquid cooled engines. They make a 600cc that is similar to the 582--I wonder if that would work for your liquid cooled engines--it is made for rotax and has their brand on the bottle--"with a name like that, it has to be good" [] Dale Seitzer--Original Firestar--447-IVO ________________________________________________________________________________

Good point. Several years ago I bought a set of aftermarket thick foam ear pads for my Blackhawk 4DX (El Cheapo) headsets, trying to get something quieter and more comfortable, and they worked real well that first year. But gradually it got harder and harder to hear the radio or a passenger. I had about decided to buy a new intercom, because my wife and I couldn't hear each other when we went flying. Instead, I called Flightcom, the company that makes the headset, and ordered their best gel filled ear pads, I forget the cost, wasn't much, and it is great, quiet, comfortable, and very satisfactory.

Subject: synthetic oil prices
Someone asked the price of Amsoil 100:1 premix two-stroke oil. I made an order for some more today so here's the facts: Retail: $90.00 for a case of 12 quarts, plus $7.35 shipping. That works out to 30 bucks a gallon, vitually the same per-gallon price as quoted for the Klotz in the post below. But remember, the Amsoil is a 100:1 premix. I believe the Klotz is formulated for use at 50:1. So using the Ams is half the cost of Klotz, if purchasing each at retail. If you are running a business, ask about establishing a Commercial account with Amsoil (800-777-7094). The price for Commercial customers is about 2/3 of the retail quoted above. I do have a Commercial account, and I do not profit from other people buying it. Just providing some facts, FYI. Jim G Amsoil 100:1 runs AWESOME. Rotax is doing tests on it now.

Everyone at the Leroy airport used the Amsoil 100:1 and no one seemed to complain. We all ate lunch together on Saturdays so I would have heard the complaints if there were any. I had very little carbon build up when I took off the heads last. It costs twice the price of regular 50:1 oil, but since you mix it half as much, it's even.

As Topher mentioned, light does travel at different speeds, etc. > Instead of 'slowed down', I should have said 'changes frequency.' As I mentioned in another post I did indeed not have my thinking cap fully on in that I forgot about what happens inside another media such as glass. Yes, since such materials have an index of refraction greater than 1 the light does travel slower through it than in vacuum. This is a result of richochetting (sp) around off molecules as it goes through the glass. Lets back up and look at what happens step by step. In vacuum light travels at a velocity of c. It is governed by two equations (1) (lambda)(nu) = c and (2) E = h(nu). The first says that wavelength times frequency = velocity and the second says that the energy of the photon equals Planck's constant times frequency. When the photon travels through space and crosses an interface into a material such as glass its velocity is decreased as mentioned above, since the glass will have an index of refraction of the order of 1.2 - 1.3. However, the two equations still apply. For the first equation the velocity is no longer c, but rather some lower value v. Thus the left side of the equation (wavelength)(frequency) must also change. Clearly there must be a change of either wavelength, frequency, or both. However, by the second equation a change in frequency would mean that there was a change in ENERGY of the photon and would be a violation of conservation of energy. The wavelength changes and the frequency remains the same. Does this mean that it is no longer UV? No, because the definition of UV as electromagnetic ratiation with wavelength below 400 nanometers is specificically related to such radiation in vacuum and does not apply in this case. The photon still has the high energy level as before with the same capability to do damage to materials. After the photon (with longer wavelength and original frequency) completes its trip through the glass and passes the interface back into space, it will resume its normal velocity of c. At this point it returns to it's original wavelength and is indistinguishable from what it was before its trip through the glass. The change only existed within the media with the index of refraction greater then 1. It is possible to create materials that will permanently alter the properties of the photon, but these are very specialized materials and the change is executed by a completely different mechanism than the one discussed above. Normal glass will indeed pass much of the UV, and as I sit here now I can look at the carpet beside the patio door and see that it is faded very significantly in color from what it originally was. Most dyes are very prone to degradation from UV. Certainly there is a diminuation of UV, but certainly not a complete elimination. Again, special materials can be made that will absorb most UV. For normal aircraft coatings the use of aluminum particles serves as a physical barrier and blocks most UV from the polyester. One can also add chemical additives (usual benzoa Triatazoles) in the coatings to ABSORB UV, but they are not nearly as effective as is the aluminum physical blocking.

Once you are sure where they go you could use epoxy glue instead of double sided tape. I don't know how many are optimal; I just put one over each rib [I wouldn't just put them on fabric with no support underneath]. With a 5 rib wing, if you have a false rib half-way between the full ribs then I would put some there; that would give you 9 or 10 per wing. Also, maybe put 3 on each side of your fuselage at the widest part; should give better air flow to the prop-therefore better gas mileage and cruise. Good luck!!

Subject: Using a Laser Level to Align the Horizontal Stabilizer...
Hello Listers, I set to work this week mounting my horz stab to the fuse and quickly realized that getting a perfect fit might not be that easy. Earlier in the week I had been talking to a friend, quite coincidently, about a cool thing called a "laser level". For those, like myself, that don't know what a laser level is or how it works here's the quick and dirty. Basically the unit is a small square box with bubble level in the X, Y and Z directions. On the top of the box is a turret of sorts with a bright red laser diode. This turret is connected to a small electric motor that spins at an adjustable rate from about 10 RPM up to about 600 RPM. This has the affect of drawing a red line in a 360 circle around the box.

This is follow-up on my dilemma with the necessity of taking the cylinder heads off to replace exhaust gaskets. The engine is a 18 month old 447, single carb. I could probably jamb wedges down between the barrels and the lower half of the cooling shroud so I could slip the old gaskets out. I am concerned about breaking cooling fins and access for cleaning the gasket seal surfaces. I could probably slip the new ones in place after clipping off the lower part of the gasket where it locks into the positioning clip of the shroud. I will be out of town for the next four days so that will give me time to get the new gaskets and ponder my options.

Hi Gang, Finally got a harness made up for my new Microair 760 transceiver. Works fine when headset/mic (David Clark) is plugged in but when used with the Telex PC-1 intercom it emits a loud squeal (feedback) when the mike is keyed and is thus unusable. Somehow the intercom is picking up the RF and routing it back into the headset. Wondered what intercoms are in use out in Kolb land that would work. Thanks in advance.

I had a chance to talk to Mike Kelly of Sigtronics while at Lakeland. He is anxious to help out the Lt Plane, Ultralight community with a good workable intercom system for our applications. Right now their expertise in our area of "NOISE" is not too good compared to their work in the GA, helicopter, and War Bird areas. Mike did not hesitate when I mentioned some sponsorship with my flight this summer. Sigtronics upgraded my intercom, sent me a new wiring harness (the one that Mr. Swuirrel ate) and two new M80HD mics and muffs, at no charge. I, in turn, will help them come up with some numbers or whatever, plus test the systems for them, so they can come up with a new improved system. The SPA400 worked great until I pushed up the power. Then it just amplified the noise. One new feature of the updated SPA400N is an additional wire to connect to a push to talk intercom button, rather than using VOX. Mike suggested turning up headset/earphone volume all the way, then adjust the intercom volume as low as possible. This helps control some of the noise. We have another List member using the Sigtronics SPA400N. He informs that there was a good increase in noise reduction and "hearability". Almost forgot to mention, one advantage of the Sigtronics SPA400N is "artificial side tone." Makes for much better voice control when one can hear ones self talking in the headset, rather than having that feeling that one is totally deaf.

Thanks John, I have had good sidetone even with the basic Comtronics set up, but even with the hand held I was getting feedback during transmission. The telex has great intercom; very little noise, VOX works great, but can't transmit with the Microair due feedback. The Sigtronics will be on my list once I can get some assurances that it is resistant to feedback. The Microair, by the way, is really slick. It's tiny, light and has lots of power.

i think that part of what is confusing people is the fact that some of the light is absorbed by the glass and then that energy is then reradiated off in the IR part of the spectrum. when the light goes into your car (most of the spectrum) it gets absorbed in your cars interior. then as the interior gets hot it radiates in the ir part of the spectrum and ir light tends to be bounced off glass fairly well so it does indeed get stuck in there. so your car is a great solar collector.

I asked for a radio check and they replied I was loud and clear. That was before I installed the resistor plugs and on the rubber ducky antenna. I have a whip antenna from Chief installed on the curved aluminum piece at the front of the gap seal. It points forward at about 45 degrees, but in flight bends back to straight up. I haven't used it enough yet to say whether it is better than the rubber duck. I fabricated a little pedestal mount to hold the radio and riveted it to the sheet metal in front of the left seat. It is between my legs, but low enough not to be in the way.

SORT OF. Some of you may remember my story from last fall, an extra slight knocking noise and additional vibration gradually coming up over 20 hours operation in a 582. Well, after successful operation for 30 minutes last night,, the jury is in. The problem was apparently oil-caused "carbon" deposits. For those of you in the habit of visually inspecting for "carbon" thru the exhaust port window or pulling the cyl head and looking at the piston crown--WAKE UP AND READ THIS. Both cyls' bottom rings were stuck on the intake side only. That's "intake side only". You know, the side you can't see until you pull off the cylinder. There was no buildup at all on the exhaust side, and almost nothing on the crown. Using the usual inspection procedures, those rings looked fine and free. Compression measured good, and there was no loss of power because the top rings were still sealing. It became apparent from the evidence, after talking to every expert I could show the parts to, or call on the phone, that unburned oil had built up on the pistons. I believe the Rotax stock injection oil pump was putting out too much oil. It was setup per Rotax manual instructions, using the cable, proper adjustment, the mark lined up , etc. How much? I don't know. How much is your own putting out? Are we ever really sure? Is it putting out the right ratio? Do each of the cyls receive the same amount? Is it blending with the fuel to completely distribute to all parts without buildup, or is it pumping in in liquid form and not really atomizing to give it a good shot at combustion? Lots of assumptions here. My best local mechanic said it this way: "The only way you're going to know that each cylinder is getting the right amount of oil every time you run the engine is if you put it in the fuel at the desired ratio yourself". I had already come to that conclusion, so I pulled off the entire injex system, from the gear to the hoses. I cut out a little block-off plate and bolted it over the hole in the manifold that used to accept the pump, removed the tank and hoses, put the shorter head studs back in, blocked the oil-inlet ports in the manifold, etc. Saved me 6 pounds over a 2/3 full oil tank flight. And now I know my engine is receiving the correct lube at the desired ratio (which I can confidently set at 100:1, 95:1, 50:1, 73:1 or anywhere I want). Of course Rotax knows best and the injex system is a fine pc of machinery. It is so convenient, just dump in the oil, no measuring, no thinking. Pre-Mixing is so messy and time-consuming (not!). I am not advocating removal of your system. I am simply telling you my experiences. The answer to your next question is: "I was / am using Amsoil". The engine was spotless everywhere but on the intake side of the pistons. The cross-hatching was all still perfect, the bearings were shiny clean and free and quiet, the crank was clean and perfect. The combustion chambers were nearly clean. Admittedly, different oils will mix and atomize and protect with different properties. It is likely that another brand oil mixes more readily and may not have caused this buildup. It is also likely there are many oils with lower film strengths, poor corrosion protection, combustion deposits, etc. After three years in a dirt-floor hangar I was happy to see such great corrosion protection. I feel satisfied with the oil's performance, but wish to control its distribution and ratio closer than is possible with the stock pump. And it is one less thing that can fail, even if the odds are small. A completely failed pump would be the end of the entire engine. By the time it came to a stop (probably seizing and sizzling), the crank would be scarred and possibly bent, the bearings and rods would be overheated badly, the cylinders would have piston smeared into them. You could salvage the exhaust and the carbs I guess. And you'd never even have an indication on a liquid-cooled engine until it started to slow down. And if you're lucky you'd land without bending your airframe. As side benefits besides eliminating possible pump failure, I saved six pounds weight, the blunt non-aerodynamic flat front-end of my engine just got 25% smaller with removal of that oil tank way up top out front, my cylinder-to-cylinder EGT difference is smaller now, the engine is noticeably simpler-looking now, and inspection and service on the intake side is easier. OK, let me have it. Jim G ________________________________________________________________________________

Jim: I should admit my bias up front in responding to your post on oil injection. I premixed when I had a Mark 2 with a 503, and when I built the Mark 3 chose the 582 in part because I wanted oil injection. I have two observations right off the bat: first, you were using Amsoil, which as I understand it is recommended at 100:1. If you were running it in the stock 582 you were getting 50:1. That's twice as much oil as you were supposed to get. Do I have that right? Second, is my understanding that Amsoil is not a Rotax approved oil. (I'm sure I will be corrected if I am wrong about that, but I'm looking at 10.2.3 of the 5/1/99 revision of the opperator's manual and it's not there.) You didn't mention your total time on the engine. Did you do the recommended 150 hour teardown? I'm on the other side of the fence from you on this but I am vitally interested in the debate, because I am running a 582 as well. I set a lot of store buy the guys at lockwood. They are Rotax approved and run 582s in their aircams. When Kerry Yunck told me he had a 582 with 1200 hours on it with NO problems he got my attention. They run Amoco premium, Pennzoil and they follow the Rotax recommended maintenance schedule religiously, including crank replacement at 300 hours. My approach to running my engine is "monkey see, monkey do." I am doing exactly what lockwood does. And I am operating my engine rigidly within the book temperature parameters. I understand your view that premixing removes a possible mechanical failure scenario. But don't fool yourself, it introduces another: human error. I think the esteemed Mr. Pike pointed out a while back that the ratio-rite cup, which is the almost universal tool for making premix, has a noticeable error built right into it. I would welcome your thoughts. ________________________________________________________________________________

It seem to run better now than it ever has. I vote to leave it on and make sure you always check the oil level before you fly. Rings usually stick on the intake side right below the upper ring gap and above the lower ring gap. I can't see the resoning for tearing down a 2 stroke just because a ring is slightly stuck if it starts fine and performs fine. I also can't see the rings stuck at 6000 RPM either, although there is a slight possibility that I could be "Wraung". I have been running my 582 at or above 5800 ever since John Hauck told me how he ran the 2 strokes he used in his early days of flying ULs. It sure has helped to keep the carbon down and the power up. The fuel consumption has gone up per hour but I get there sooner and the miles per gallon are about the same if not a little better. It's been over 350 hours since I went into the top end down to the pistons. I plan on doing a lot of flying this year (300 hours or more) and hope to see some of you at fly-ins around the country. I don't plan on doing any tear downs until this flying season is over, maybe this winter. I am not worried about my 582 or the oil injection system getting me there and home again. I worry a lot more now about T-storms and fog and rain and wind and all the other things that can go wrong on long cross countries. We had a little of it all going down to Sun-N-Fun this year. That made for a very interesting flight. And by the way you might get to read about me and my plane in UL Flying Mag sometime this year if they don't run out of space. Running your Rotax at below 5800 rpm for extended periods will some times cause a build up of carbon. 100LL will cause a lot of carbon build up. I have been told for those who premix with Amsoil that it has a hard time mixing with 100LL in certain conditions even at 100-1. Lockwood does have the record of good performance with Pennsoil and the injection system. If you stay with it and learn to operate it correctly I am sure you will have many hours of trouble free flying just don't ever forget to check the oil in the oil tank every time you put fuel in the fuel tank.

Gentlemen: Permit me to stand on the soapbox for a moment. One of the things I have complained about bitterly over the years has been Rotax's incomprehensible stupidity in not publishing decent manuals for their engines. Anyone who hangs around the aviation business knows that lots of folks wring their hands and moan about how aviation companies get sued too much. But if your customers have no idea how to operate your product they are going to get hurt, and what can you expect? As a lawyer involved in the defense of aviation manufacturers I sometimes shake my head and wonder why it takes so long for the message to get through. A simple example of this is aircleaners on Rotax engines. The barrel we clamp the aircleaner to is smooth and relatively short. Not a lot of area there to clamp to. As a result, departing aircleaners have been suspected as a contributing factor in a number of accident with pushers. Finally, after all these years, Rotax has started putting threads on the outside of the barrel so the rubber aircleaner gets a better purchase on the carb. Hooray, I say. But I still shake my head a little. There was an accident in Ohio with a 582 where the carb/aircleaner attachment was a problem. By the time it is over Rotax and bombardier will have spent enough money on legal fees to thread the barrels on all our carbs and send us all new gold plated rubber carb sockets. I will be the first person to point out that lawyers make lousy engineers, but sometimes the only way to get a company's attention is to put your hand in their pocket. My point is this: I just love it when management gets the message that tiny, incremental, product improvements can save huge dollars in the end. Rotax seems to be getting the message guys, and that is good news for us. Rotax has taken a step which I applaud. They have revised the service manual and operators manual and put them on the web to download for free. This is almost too smart for words. See them at http://www.kodiakbs.com/ As you might expect I have been pouring over them. There are some very subtle and interesting changes. The guys in Austria are sending us messages . . . we should pay attention. As a 582 operator I am deeply concerned with the whole cold seizure scenario. The first thing I did was turn to the operating parameters for the 582. Some very interesting changes. First, they have put a 5 minute restriction on full power 6800 rpm operation. That's new and interesting. They say cruising rpm is 6500. And the normal egt range is now from 930 f (lower I think) to 1150 f, with a max differential of 43 f. Most interesting to me is that they have significantly narrowed the allowable water temp green arc for the 582. It was 140 to 180. The current recommendation is 150 to 175. I think the message from Heinz is that we should be running our engines hotter. I think a lot of the bad rap two strokes get comes from folks who are clueless about how to operate them in airplanes. Some of that can be attributed to Rotax because they have done a lousy job of making that information available. Some of it may be a result of the fact that most of the gauges made for this application are of low quality and therefore produce unreliable information. The light experimental aircraft business is maturing, Rotax is trying to make a better engine (witness the 582/2000) and they guys at Kolb are doing their darndest to make a better product. We as operators have got to do our bit too and lift our own level of sophistication. I encourage all Kolbers with Rotaxes to check out the new manuals.

I replaced it because the back connecting rod had worn to its allowed limit. The front rod was still well within the limits. The seals were still good and I wasn't having any problems with the mechanical parts of the engine. I had gotten twice the life out of it I was suppose to and I felt that that was enough. I will inspect this crank at 1100 or 1200 hours for wear and don't expect any. I have run Pennsoil ever since 300 hours with only minor ring sticking, found after I actually pulled the cylinders off when I replaced the crank. My compression is still over 110 at any time. I have to say that because if I check it stone cold it is always higher. A warm or hot engine will give you a little lower reading on compression sometimes. I've found that if the compression gets below 100 I start suspecting ring sticking. It is harder to crank and the plugs have to be change more often, not that the're worn but just because a new plug will fire better than one that has a little time on it. I don't quite understand why that is but it happened to my 582 back when I was using Walmart oil. Hard to crank, lower compression and having to change plugs to get it to crank sometimes. I'm not trying to plug Pennsoil but it sure has made my flying a lot less hassle and worry free. All our club members (about 15 flyers) use it and all of us get very good performance. I had been thinking about another engine but with the way this 582 is performing I might just see how many hours I can get on it. Heck, I've never even had to do anything to the starter which is mounted in the E-box. I did check it at 600 hours but it looked new and the brushes were just beginning to show a little wear. I've never had to change the exhuast springs either. They just don't seem to wear at all. But then I do lube them once in a while with silicon and I do have a safety cable run through them just in case. It has had it's problems but they were for the most part caused by me. I suppose I could say I have gotten my $s worth out of this 582, now it is paying me back in dividens, hour after hour.

Mark, You said a mouth full. And I agree. It is like this in almost every industry. We are the ones that have to force the change but it takes a lot of energy to change the course of an ocean liner if you want to do it in a hurry. But all energy that is placed upon it will eventually change its course. The squeeky wheel gets the grease. Firehawk >Gentlemen: Permit me to stand on the soapbox for a moment.

Subject: fuselage tube alignment
Fellow Kolbers I'm building a Firestar II and I got a question. I'm in the process of the fuselage boom alignment with the cage and then the h-section installation. I very accurately measured the center of the fuselage with the paper strip method several times to make sure it was right and am confident it is. If I use the 7/16 in. spacing between the cross member at the rear of the cage to the boom tube it puts the center of the boom tube almost a 1/4 inch out of center with the two 3/8 inch holes that are to be bored in the boom tube for the h section. Correct me if I'm wrong, but the h section is going to fit so tight in the fuselage that it has to be aligned down the center of the fuselage tube. If I bore the 3/8 inch holes were they end up using the 7/16 distance from the cross member, I don't think the h section would be able to line up with the 3/8 inch holes in the tube unless it was permanently mashed out of round. The main thing that worry's me is that if I don't use the 7/16 inch spacing it's going to change the angle the boom tube makes with the fuselage cage but if I do, then the h section ain't gonna fit fuselage tube. Has anybody else out there ran into this situation? Ron Williams ________________________________________________________________________________

Subject: Re: fuselage tube alignment
Ray, Mines not quite the same problem. It's in the vertical alignment of the fuselage tube. In effect, the plans say with the tube in the steel ring to pick the tube up in the vertical until it is 7/16 of an inch from the small horizontal cross member tube that is about 3 inches above the 3/8 inch holes in the fuselage. When I do pick the fuselage tube up to within 7/16 of an inch from the cross member then the center line of the fuselage tube goes past the center of the pre-drilled 3/8 inch hole in the fuselage frame by almost a 1/4 inch. If I were to drill it there i would never get the h section to line up with the holes. The only problem I see now if I do drill it in the center of the tube where it looks like it should go any way is that the fuselage tube will be slightly closer to the aileron bellcrank arms by about 3/16 of an inch. which already looks mighty close. Thanks for your reply Ray. I'll just have to give it some more thought before I drill. Ron >I think you may have the same problem I encountered on my Mark III.

Hi Ben: My experience so far is a little limited, but what I've found is that glass beads do a great job for general cleanup, and seem to be fairly "gentle" on the material being cleaned. For tougher work, such as hard scale, and heavy rust, silica sand works like magic, and leaves more texture on the part. I think care would be advised on structural components like fuselage tubes, etc., to make sure the base material isn't eroded too much. Co-incidentally, when I was involved with this - with an inexpensive blaster - I happened to pay a visit to my local powder coating outfit for another problem. I mentioned what I was up to, and he offered me all the sand I could use or want - free for the shovelling. He says that after a couple of uses, the sand gets too fine for his needs, and he has to throw it away. I took home 15 gallons that day. Fine or not, it sure works "fine" for me. I'll say this too - after using the blaster, sandpaper will only be used for small jobs that don't rate setting up the blaster, or where getting the sand near sensitive components would cause a problem, such as engine intakes, etc. I've also learned to put a large sheet of visqueen under my work area, with the edges propped up a foot or 2, to catch the worst of the media. Sure makes clean-up a lot easier.

Ben, I have been sandblasting my antique tractors and stationary gas engines for about 23 years, and I could talk to about a week on this subject. anyway remember, sandblasting or bead blasting is a process as well as silica sand. depending on what type of steel or cast iron ( gray cast or white cast) you are blasting and how rusty or pitted the metal may be, you should probably start with a medium or course bead, it comes in fine, medium and course. the fine grit for example would be used for polishing the top of a piston head, also remember to match your compressor cfm to you gun (recovery rate) or you will be blasting 20 seconds and waiting 4 minutes for you compressor to catch up, it's like cutting a hole in the tank of the compressor, they take alot of cfm's to operate a blaster. tank a look at this site and see if it will give some good info about blasting, if not you can e-mail me and I will try and help you out. http://old-engine.com/abrasive.shtml Ben Ransom wrote: > > I see Grainger has an inexpensive sandblaster and I'm thinking of > getting one.

Amsoil (and most others) easily exceeds all current and proposed certifications. Is Pensoil on that list? Are there any synthetics listed? How about Phillips Injex? There are probably a dozen other excellent lubricants that people are using successfully that are not on Rotax's list. I understand that one can now access the latest operators' manuals online.

Mine was based on my first-hand evidence of oil not atomizing well enough to find its way thru the combustion process. It is a statement of the oil and the delivery method. I no longer blindly hope to pump the oil in with no idea how much is reaching each cylinder, in liquid form hoping it mixes well enough to lube everything, having it pass into the process only partially blended with the fuel/air mix. I am now blending it finely into the fuel in the proper ratio (I can tell you what ratio my front cylinder is receiving, can you do this?). If my engine is running, it is receiving the proper lubricant, no question or debate there. > My approach to running my engine is "monkey see, monkey do." I am doing >exactly what lockwood does.

Yup, in small quantites especially, the process is prone to error. Today I use a 33 gallon barrel with pump and filter, to transport my Amoco Silver to the field. I mix at the gas station pump. I dump in two gallons of fuel, then add a quart of Ams 100:1, then slosh, then 23 more gallons. Driving the ten miles to the field over the worst road ever made doesn't hurt the mix either. Before using any fuel out of the barrel, I put the end of the fuel hose in the barrel fill bung-hole and recycle-pump it for a couple minutes. If forgotten altogether, the absence of the oil in the mix would be immediately visible in the filter housing as the wrong color. Thru all this handling and then the act of pumping it into three seperate tanks, etc., it is blended very well. My barrel-pump balked badly for two years on straight fuel, now it purrs like a kitty on premix. FWIW, Jim G ________________________________________________________________________________

Subject: fuselage tube alignment
Date: May 01, 2000
Ron; In building my FSII I found that the left and right parts did not have the same for hole alignment and positioning. I had to fill the hole and redrill or cut and reweld several of the chromally parts. I would put the H section in where the plans indicate and fit the boom into the ring, align the boom to reference strait to the fuselage cage and determine which of the two hole needs to corrected, fill the one that is off and redrill. Others may disagree with this process but it worked for me. You may also find that the boom does not fit into the ring correctly. It may need to be notched as per the plans or it may need to be trimed at an angle to get the correct amount of material into the ring for the bolts to have the proper amount of edge metal. John N670JW -----Original Message----- From: RWilliJill(at)aol.com [mailto:RWilliJill(at)aol.com] Sent: Saturday, April 29, 2000 12:32 PM Subject: Kolb-List: fuselage tube alignment Fellow Kolbers I'm building a Firestar II and I got a question. I'm in the process of the fuselage boom alignment with the cage and then the h-section installation. I very accurately measured the center of the fuselage with the paper strip method several times to make sure it was right and am confident it is. If I use the 7/16 in. spacing between the cross member at the rear of the cage to the boom tube it puts the center of the boom tube almost a 1/4 inch out of center with the two 3/8 inch holes that are to be bored in the boom tube for the h section. Correct me if I'm wrong, but the h section is going to fit so tight in the fuselage that it has to be aligned down the center of the fuselage tube. If I bore the 3/8 inch holes were they end up using the 7/16 distance from the cross member, I don't think the h section would be able to line up with the 3/8 inch holes in the tube unless it was permanently mashed out of round. The main thing that worry's me is that if I don't use the 7/16 inch spacing it's going to change the angle the boom tube makes with the fuselage cage but if I do, then the h section ain't gonna fit fuselage tube. Has anybody else out there ran into this situation? Ron Williams ________________________________________________________________________________

Subject: Kolb components wanted/available
Hello Group, I recently purchased the remains of an Ultrastar. The pilot, "damn the torpedoes...full speed ahead", flew in adverse wind conditions, knowing full well it was too windy. Well,.. until turbulence ended the flight and flying status of he and the plane. He is doing just fine now (a tribute to steel tube cages!). The plane did not fair as well. Kolb does not support the Ultrastar, but I understand that the wings and tail group are the same as the Firestar. They want a lot of money for needed items. I have a right wing (with minor damage) and a good tail group. I have the choice of trying to locate a repairable Firestar fuse, as I can do the steel tube fitting and welding, and build/buy a left wing and the other necessary components. Or I can sell these components to someone needing repair parts, or "prebuilt" tail group. The other options of scratch building a fuse, such as the Legal Eagle will require more time than I can provide right now. Any words of wisdom? I have enjoyed reading the support info of this site.

Duane, I hope you took my previous post with a grain of salt... I've been drinking too much of that cranberry-blackcherry juice. Before it wears off I tell you what I really think! Before the days of the MKIII, a lot of the "big boys" were putting 532's on their Twinstars, much to the chagrin of Homer. I haven't heard of anything catastrophic happening because of that combination, but then there's a lot of things I haven't seen & heard. Other than reliability, the 532 isn't that much different than the 582 as far as power & weight goes. As far as I fallibly understand, the FS-KX, FS-I, FS-II, Twinstar & MK-II all have the same basic wing constuction. The FS's would almost certainly have a aft cg problem to overcome & you probably would self destruct it in straight & level full throttle flight. If you restricted full throttle to take-off & climbout & had the will power to intelligently manage the throttle thereafter, it is not a totally crazy thought. I wouldn't recommend it to my son, but if I had a Fire Star I & a 582 laying around I would pursue the idea of that very tempting match. The problem with this combination is that it would demand a vigilant pilot that could not be lured into the "never to exceed" zone which it would easily be capable of doing. ...Richard & still over top dead center of crazy Duane & Eloise Geater wrote: > > Are there any firestars flying with 582 engines and if so ,please tell me > the good and the bad. > > Duane Geater > ________________________________________________________________________________

Subject: SA on GPS
Date: May 02, 2000
Got this from other chatlines (homebuilts and UL). Just a note to say that SA has been turned off making our GPS units about 10 times more accurate. Garmin says their hand held units will be accurate to 20 to 30 feet, and the altitude function will actually be useful It's finally happened. Now, why exactly is the FAA still spending all that money on WAAS/LAAS?? THE WHITE HOUSE Office of the Press Secretary _______________________________________________________ For Immediate Release May 1, 2000 STATEMENT BY THE PRESIDENT REGARDING THE UNITED STATES? DECISION TO STOP DEGRADING GLOBAL POSITIONING SYSTEM ACCURACY Today, I am pleased to announce that the United States will stop the intentional degradation of the Global Positioning System (GPS) signals available to the public beginning at midnight tonight. We call this degradation feature Selective Availability (SA). This will mean that civilian users of GPS will be able to pinpoint locations up to ten times more accurately than they do now. GPS is a dual-use, satellite-based system that provides accurate location and timing data to users worldwide. My March 1996 Presidential Decision Directive included in the goals for GPS commercial and scientific applications worldwide; and to encourage private sector investment in and use of U.S. GPS technologies and services.? To meet these goals, I committed the U.S. to discontinuing the use of SA by 2006 with an annual assessment of its continued use beginning this year. The decision to discontinue SA is the latest measure in an on-going effort to make GPS more responsive to civil and commercial users worldwide. Last year, Vice President Gore announced our plans to modernize GPS by adding two new civilian signals to enhance the civil and commercial service. This initiative is on-track and the budget further advances modernization by incorporating some of the new features on up to 18 additional satellites that are already awaiting launch or are in production. We will continue to provide all of these capabilities to worldwide users free of charge. My decision to discontinue SA was based upon a recommendation by the Secretary of Defense in coordination with the Departments of State, Transportation, Commerce, the Director of Central Intelligence, and other Executive Branch Departments and Agencies. They realized that worldwide transportation safety, scientific, and commercial interests could best be served by discontinuation of SA. Along with our commitment to enhance GPS for peaceful applications, my administration is committed to preserving fully the military utility of GPS. The decision to discontinue SA is coupled with our continuing efforts to upgrade the military utility of our systems that use GPS, and is supported by threat assessments which conclude that setting SA to zero at this time would have minimal impact on national security. Additionally, we have demonstrated the capability to selectively deny GPS signals on a regional basis when our national security is threatened. This regional approach to denying navigation services is consistent with the 1996 plan to discontinue the degradation of civil and commercial GPS service globally through the SA technique. Originally developed by the Department of Defense as a military system, GPS has become a global utility. It benefits users around the world in many different applications, including air, road, marine, and rail navigation, telecommunications, emergency response, oil exploration, mining, and many more. Civilian users will realize a dramatic improvement in GPS accuracy with the discontinuation of SA. For example, emergency teams responding to a cry for help can now determine what side of the highway they must respond to, thereby saving precious minutes. This increase in accuracy will allow new GPS applications to emerge and continue to enhance the lives of people around the world. 30-30-30 ________________________________________________________________________________

Subject: It's Tuesday Night! Story Time
Tuesdays Story Hour Since this is a bit long, Im making it a two-part story, with the second part Friday night. If you gentle readers dont like a truncated story, please tell me--and I wont do anymore cutting. May have to have a long one once in a while. Ok, settle down, and listen: Eyes Toward the Skies The bleak Nebraska plain had few interruptions to the monotonous sight of prairie meeting endless sky. A lonely cottonwood tree breached the near horizon, keeping company with the barn and other outbuildings. Otherwise nothing. Robbie's father said he could see fifteen miles sitting in the saddle, ten more of the same standing in the stirrups. An occasional chicken hawk circled overhead, some carrion-eater watched for the leavings of a coyote, nothing else but the ranks of towering cumulus clouds inhabited the vast dome smothering Robbies provincial world. Not until the day the air mail planes started their erratic crossings of his private sky did he ever spend any time looking up. There was no reason to look up, except to gauge the time of day from the sun, or to judge the weather. Now a new object of interest made its way across the blue dome, passing beneath the clouds, outlining the plane's image against the brilliant white, much like the moving pictures shown against the near-by town's white feed mill wall on Saturday nights. The mail flights became more regular, but even then there were times in bad weather when the plane was so low the pilot could be seen peering from the cockpit to find his way in the torrential rains, locally called frog-stranglers. With thousands of acres of board-flat land, it wasn't uncommon for mail planes to make precautionary landings - off times reported in the local weekly as a "forced landing." One early pilot, after an abrupt descent into a barnyard, telegraphed his home field: FORCED LANDING. KILLED COW. SCARED ME. As the airmail route seemed to pass over the ranch, the 189 young boy was soon able to mark the schedule, and sometimes waved a bed sheet at the passing plane. Usually the plane was too high to see him, or more probably the pilot was not looking straight down. One day there had been ominous weather conditions all morning, lines of marching cumulus, with gray-green bottoms, and a heavy stillness shutting out the usual prairie winds that seemed never to cease. Rob kept watch after lunch, looking up from hoeing sweet corn in the truck patch, listening for the now-familiar engine in the afternoon sky. The clouds were quite low, lightning was forking down in the west, accompanied by a distant gray haze that he knew was literally sheets of water. How would the mail plane get through this deluge? He had no idea how pilots guided their machines, even through clear skies, much less in what was now becoming a black wall. Unexpectedly the mail plane swooped low over the cottonwood, turned, and headed for the farm house at what appeared to be windmill-height. The boy could clearly see the aviator, with his goggles, brown leather cap and ear flaps fastened under his chin. The pilot made another turn over the windmills vane, then headed out towards the west. Rob was greatly excited, thinking the pilot had "cut some didos" just for him, and chagrined he had been too awed to wave. His disappointment turned to joy, then concern, and finally terror when the plane's engine turned from the familiar roar to a sputtering cough, then silence. The plane, very low, seemed to hang in the increasingly strong wind. Finally it dropped with a gentle bounce to the almost endless sod. The boy raced across the farm yard, scaling the "bob-wire" strands and hoping the plane would stay there long enough for him to approach it. The 190 slightly curved wooden blades at rest; popping sounds came from the hot engine as it cooled. The De Havilland DH-4, with its mighty Liberty engine loomed above Rob, larger now that it was finally in his pasture. The pilot levered himself out of the rear cockpit, shucked off his cap and goggles, and swung over the side, dropping to the dry sod. Rob panted up, completely out of breath, unable to say a word in the presence of this airborne hero. "D'you think it's gonna rain, son." Rob found his tongue at last and replied in his flat Nebraska accent: "When the sky looks all green in the west, we're gunna have a real bad thunderstorm."

I do a fair amount of aircraft parts. a J - 3 fuselodge costs about 250.00 to sand blast. or at lest that is what I charge. smaller ones would be cheaper. the average small garage air compressor has a hard time keeping up with even a very small sand pot. some of the larger garage compessors can put out up to 175 lbs this much presure can do more damage then good. it will warp light sheet metal and make it look like it came out of a hot fire,. pecan shells work very good for cleaning up small parts and aluminum sheet metal. you can clean up motors and not worry about sand getting in were it is not suposed to be. pecan shells will not etch the metal. A small pot should be a pressure type not a syphone. do not use play sand to try to blast with.It is not graded for sandblasting you can not adjust the sand flow.

My friend is not on the internet, so he asked me to post this question for him. Anybody out there have Kolb's instructions/drawings that they can send me, so I can forward them on to him? If Kolb doesn't supply any instructions/drawings, is anybody out there willing to give me your name/phone # so that he can call you with some questions he has? If you don't want your personal info posted to the archives, then jut send me a personal e-mail at moravan(at)seanet.com. Anyway, thanks for all of your help. Best regards, Greg Moravan 425 450-9745 FAX 425 450-0195 Issaquah, WA N82GM Mark III/912 ________________________________________________________________________________

To Greg asking about the Dual Controls, I have a print of the dual controls that they sold about two years ago. They have changed to a different type now I think. Do you know how long ago he bought them? I would be happy to scan the print I have and e-mail it to you. Just let me know.

Subject: too windy
Someone posted; > >I would like to know what oter kolbers consider "too windy". Comments please. This really depends on the model you are flying, its ramp weight, and your skill level. I can speak for my situation. Mine is the MKiii, it takes off at about 790 pounds with me, gear and fuel. I have flown when winds aloft were 28-35 mph, but at ground level were 15-18. This would be frustrating if you were trying to go somewhere, but it was an interesting experience since I was only goofing around the patch. I could register very low (0-5mph) speeds on the GPS if carefull (at 3000 feet for safety!). Ground handling is tricky above 15-18 mph, I have made cross-wind landings now with 90 degree 15 mph winds and that is close to all the rudder is good for. If the wind is constant it adds more interest to the flight. If it is gusty, it makes the flight much less fun, and those are the days you may bend landing gear.. I will answer your question by saying that FOR ME "too windy would be winds straight down the runway greater than 20 mph, 90 degree crosswinds greater than 15, or very gusty conditions". If I was using oil injection, I would have to subtract 5 mph from each of those values (just kidding!). Jim G ________________________________________________________________________________

As far as I know there is no actual solvent for silicone. And it seems to migrate. Once on a surface it kinda gets everywhere. Glad to know this about waxes and siicone.

Hello list. I'm a new guy to the list. Private Pilot SEL rated but haven't been PIC for 8 years. Looking to get back into flying, considering ultralights and really like the Kolb design. Painted lots of cars and some airplanes 20 years ago, and did a bit of A&P work back then too. I live in Concord, California. Fabric repair and painting with silicon on the surface is a dog. Most important is to clean the surface thoroughly before starting any repair. Clean well beyond the "feather range". Ditzler made (makes?) a good wax and grease remover, DX-440, for this purpose. Make sure to wipe it on wet and wipe it off while still wet with a dry cloth, repeat this process several times and the silicon problem will be reduced or eliminated.

Subject: Update on N101AB (Miss P'fer)
Morning Gang: My hands and fingers are so stiff and sore it is difficult to type this morning. That's what happens when we age, spend several days trying to get the fuel system and lines in the right positions and configurations. Its a bear pushing neoprene lines on AN fittings, then pulling them off and trying something again, and again, and again. Heck, I thought I had it right the first time in 1992. :-) Finally got it together the way I wanted it (the fuel system) about 2000 last night. I have a loop of fuel line from the tank outlet (lowest point of 25 gal fuel tank) down under the tailboom and up to the Facet fuel pump. At the bottom of the loop is a "T" fitting, drain line runs forward to the lowest point of the fuselage where there is a drain valve. A very inexpensive "gascolator" that gets the job done. Lengthened the fuel site gauge to indicate when the engine is going to stop because of fuel starvation. Old sytem was good to about 4 gal remaining, but that was with the fuel at the bottom of the site gauge. The last 4 gal was run on the clock and guessing. Very uncomfortable feeling. New site gauge is accurate down to .5 gal remaing when fuel is at the bottom of the site gauge. Right now, before I get to actually fly and test the new 912S, looks like about 6 minutes flight time left when gauge indicates empty. No 20 minute warning light here, Gang. Miss P'fer better be on the ground before fuel hits the bottom of the gauge. Still got to rewire intercom, radio (damage the squirrel did, and something I have been putting off until the last because I do not want to do it); install throttle and enricher cables; fill with oil and prime oil pump; fill cooling system; check out everything real good, then hit the start button for the first time (maybe today, I hope). Woops! Forgot to put the 72" Warp Drive on. Better do that before I hit the start button. After we get the engine running we will finish up the BRS installation in the center section. Took several weeks to figure out how to install the new parachute. A little more difficult than my old 2d Chantz. Coming up with the best workable solution for installing equipment is time intensive. As soon as we get everything "tidy" (wash 4 months of dust and crud off the MK III) we will be ready to test fly. One other thing and I will shut up, "the wind." Don't know that there are any hard numbers for max wind or crosswind component capability. My rule of thumb is, "I don't fly if it is not comfortable." When it ceases to be fun, time to land. All Homer Kolb's airplanes have the ability to fly in a lot a wind. I do not know how much. We demonstrate their capability, pretty much, at Lakeland and Oshkosh almost every year. We feel this is a "feather in our cap" because usually when things get real rough, only the Kolbs will still be in the air. On most of my long XC flights I encounter extreme winds, winds I do not want to be up in. Sometimes I have to fly these winds to make it to the next place to land. Several times during 1994 flight the wind overpowered the rudder. I mean I could not overcome the "weather vane" effect of the wind. Usually, if the wind is blowing that hard, the Kolb will land into the wind in a couple feet, which means at a "real" airport you can land across the runway instead of down it. I was ready to land at Grenada, California, but the wind, out of the west, was overpowering the rudder. The single runway was 36/18. I decided to fly a little further to Montague. They had a crosswind strip. No problem. Next leg was to Ashland, Oregon, up I-5, thru the pass. Wind beat me up and scared Hell outta me. Landed at Ashland with the wind on my nose. Did not roll out more than a plane length. Very cautiously taxied to tie-down. I think the important thing to remember when "caught in high wind" is to stay "cool", keep the nose of the aircraft into the wind, let the airplane fly, keep a good margin of airspeed over stall, do not try to overcome or fight the wind, take your time and find a safe place to put it on the ground. A bush pilot in Alaska told me not to worry about terrific downdrafts, I would not be blown into the ground. The wind has to go somewhere and it is not into the ground. I believe him. This is how I do it. I am not telling you to fly like I do, but it does work for me. Take care, john h ________________________________________________________________________________

Arizona is a flying heaven, with over 306 days per yr of VFR weather. In the Phoenix area, October through April is great, with temps in the 40-50 range every morn, and 70-80 range every afternoon. Summers get rather hot and can be very turbulent in the afternoons so most of us don't fly ultralights much in June, July, and August. I've explored all over southern arizona and have landed all sorts of places in the desert, on the indian reservations, on dry lake beds, and of course on the zillions of dirt runways and old airstrips all over the place. It's the safest place to fly in the US IMHO, engine out, no problem. Now, Northern parts of AZ are more scenic but loaded with canyons and mountains. Much prettier, but treacherous. I'd like to fly the Moggolon rim, Monument Valley, Meteor Crater, and Marble Canyon. Now, the Grand Canyon would be fun to fly too, but very illegal, and you would annoy a lot of people who would be sure to turn their photos of your plane over to the Feds.

Also, it takes VERY little to produce Fisheyes. Anyone who has ever encountered fisheyes knows what a struggle you have ahead of you if this happens. The surface energy altering properties of silicones is exactly what makes them very useful in some areas and very deadly in other areas. It is for this reason that PolyFiber warns against using "used and recycled" shop towels, as they may have been contaminated in the past.

Thanks Everyone, Yes, I was concerned about the high voltage! And, I was impressed with the nice constant output, I guess I should have been more specific in my original post. I was thinking about using the regulator to power my new Icom A-22, however, the Icom book says the max voltage should be no more than 15 volts and I would hate to be running at the max allowable voltage if you know what I mean. The book also stated at 18 volts an over-voltage screen would appear and you should disconnect the radio from the power source when this happens. ----Like I'm really going to notice a warning on the screen if the regulator decides to put out another couple of extra volts.

Subject: Top end de-carbon report
Following Stratman's analytical engine tear down procedure I found that, with the cylinders removed, 3 of the studs were only finger tight and showed no evidence of Loctite as recommended by Rotax. This could explain the oily seepage found on the back of the engine at the cylinder-to-head interface. The head gaskets did not show any signs of a blowing leak or erosion. All studs were locktited (new verb), retorqued to 60 in/Lbs.This same engine's factory-set electronic ignition was out of time and had to be reset. Resetting did not make it run any cooler. It must have been assembled on a Monday after Octoberfest. One problem I plan to solve is the possibility of pieces of carbon/grit falling into the crankcase while the pistons are being cleaned. Stuffing rags in all the openings looks like a poor solution. I think I'll try to make a closure from .016 Al that will fit under the piston skirts to make sure the crankcase stays clean. As usual I will make the patterns available to the List. Duane the plane in Tallahassee, FireFly, 447, IVO, big wheels ________________________________________________________________________________

Subject: Windsor club update
Just wanted to keep you guys informed on the club project. We have been working on it for 6 weeks now one night a week for 2 1/2 hrs a night. The owner of the workshop spends a bit more time in there when he has some free time. So far one wing is done, the other wing has the ribs rivited on and is ready for the false ribs and the wing tip. Last night we got the fuselage up on the wheels and bolted together. Didn't do the brakes yet but we can push the frame around a bit easier. We are painting the frame with a white rust paint. It makes it a lot easier to repair or see any cracks if they decide to appear. The club is now deciding between a Hirth 2706 engine with factory rebuild or a Rotax 582 with 180 hrs on it. Even I am amazed at the speed we are going. We are also getting to work as a team now and I do not have to supervise every job. Hopefully it is because they are starting to listen when I say "What does the plan call for". Now they are more confident in reading the plans and will check before asking me. This is a great learning experience for them. My own project should start moving now I have the ribs made for the new airfoil and last week Andy and I cleaned out the hanger and we can even move around in it now. No more excuses not to build my wing. Woody ________________________________________________________________________________

The voltage is OK without a load and just a hobbs but with a battery load should see no more than 14.3v since after that point the electrolyte in a sealed/gelled battery will start to boil away/degrade. Either of these units are not really hermetically sealed and will outgas....difference is you cannot replace electrolyte as with a conventional battery. A voltage regulator is a really easy project to build as I've done several for old Lowrance Eagle units some friends had. Four components are required, all available at Radio Shack or other electronics source 1. a voltage regulator IC ( a 7812 is a 12 volt output, 7809 a 9 volt output).....input voltage can range up to 35v for either of these ICs 2. one 1 amp rectifier diode, 1N4004 or 1N4007 3. C1 .... one 4.7uF tantalum capacitor 4. C2 .... one 1uF tantalum capacitor The IC has three legs - one input, one output, and a leg that goes to ground (the center leg). The diode is connected to the battery/supply + , then the other leg is connected to the input leg of the IC. Capacitor C1 bridges between the IC input and the battery ground, C2 bridges between the IC output and battery ground. That's it. Done. Nice regulated power. Should you wish to see an example of the circuit, search for GPS NUTS and look at the home-brew connector for Lowrance and Eagle GPS's. It's really easy to build and works like a charm. About the only thing that could go wrong is getting the diode turned around so current doesn't flow...just check with a DVM or VOM before soldering and you'll easily tell which way the diode passes current. > Yes, I was concerned about the high voltage!

When you move the tail feathers forward you move the aerodynamic center of the plane forward and the acceptable cg of the plane is defined relative to the aerodynamic center of the plane. so this is a very ineffective way to get a plane into cg limits. worse yet the dynamic stability of a plane is a function of "tail volume" which is deffined as the area of the tail times its length from the cg. if you shorten the tail the tail volume goes down and your dynamic stability gets worse. a nice handleing airplane gets squirely feeling, or even uncontrollable. Do some very serious stability and control engineering before shortening your tail. Topher ________________________________________________________________________________

If you cut the tube you may change the weight and balance that you see on your bathroom scales but you are also changing the moment arm of the tail. You will decrease the effectiveness of the tail. You WILL reduce the CG range possibly to the point were you could not be able to recover from a stall. I suggest you move something heavy to the nose cone.

Subject: Key West Regulator Fix
Regarding the regulator issue, and secondary voltage regulator "fix". On occasion a primary voltage regulator will be found to have output voltage which is outside of the desired 13.8 - 14.6 range. There is a much easier way to correct the problem, with simple diodes. Yes, a secondary voltage regulator can be used, but I would approach this with caution. Jim Baker has described a simple system, however most 7812s are only good for 1.5 amps, and typically will go into shut down if they get too hot. Most are not happy without some kind of a load on them (Hobbs does not qualify). Regulator circuits can be designed to provide protection for themselves, but the circuit listed has none of this protection, or a heat sink. Spikes can be generated through starting circuits, etc., that can destroy ICs! A much simpler approach is to add a pair of healthy diodes (two in parallel, one each direction) in series with the charging regulator output-to-battery connection. With a diode "forward biased" (that is conducting), it will drop six to seven-tenths of a volt. Two diodes are required in most circuits, as the charging circuit will not "see" the battery, unless the second diode is available, biased in the opposite direction. What you now have is a bi-directional conductor that automatically drops six-tenths of a volt or so, in both directions of conduction. Make connections to the starting circuit direct to the battery. You will find that the diode voltage drop puts everything in line. Charging circuits should still be isolated via a breaker. Should the diode fail (open), everything on the battery buss will still be powered, but the battery will not be charging. If the failure mode is a short, then you are back to the original problem of temporary overcharging. Good ol fail safe. Make sure the diodes are isolated on a heat sink, but the amount of power they will have to dissipate is very low. (P=E*I.. 0.6 V x your current..) Stud mount diodes can be purchased with opposite polarity on the screw stud. Therefore both diodes can be mounted to a small chunk of 1/8" aluminum direct, with one lug/wire under either stud. Both of the "loose ends" are soldered together, forming the other lead for a neat two terminal assembly. Isolate this from the frame! One lead (either one) goes to the charging output breaker, other to the battery positive terminal. I used to design industrial electronic controls...they needed to be bullet proof. Questions?

Lar, I'm interested in the same question!!! Just helped a friend install a new 447 on his old drifter with belt drive. He can idle back to almost nothing without skipping a beat. Boy am I envious. I have to carefully manage my rpm on start up so as not to shake the engine off the mounts. That means keeping the rpm up over 2500 when first starting, which also means my FireFly wants to start moving. When warm 2200 is as low as I can throttle back to keep from chattering - still a little pushy. I'm swinging a two blade wood prop that is balanced and tracking true. Is it because of the amount of backlash I feel when moving the prop by hand? Seems like more than it should be. Terry K.

Because the Rotax engines have fixed ignition advance. I have the aftermarket CDI ignition from Arizona (forgot the company name, it's the guy in Arizona that rebuilds crankshafts, he is very helpful) and the 532 will rattle just like every other Rotax at around 2000 rpm, it is still at full ignition advance, but when it drops to 1500 rpm, the ignition timing retards notably, and then the idle smoothes right out, and it will sit and idle smooth as silk at 1000 RPM. Just for the heck of it, we tried to see how slow it would run, we got it down to 800 rpm smoothly, and then it started to get unreliable, kind of like it was losing interest. Years ago my father in law had an old BSA English Army courier motorcycle, and it had one grip for the throttle, and the other was for spark advance. When you retarded the spark, that thing would sit and idle wonderfully slow, a really smooth thumper. So it's all a function of ignition timing IMHO.

Subject: gear box design
Date: May 06, 2000
A main contributer to gearbox chatter is torsional resonance. the whole system, from the pistons to the prop has a natural frequency that can be excited by the power pulses of the engine. Once resonance starts each power pulse adds energy to the system and will eventually break something. You dont want to operate the engine at any frequency that feels rough for any length of time. A belt drive or chain drive will have very different natural frequencies then a gear drive. When we designed the redrive for the Powersport 215 HP rotary engine we designed it to be so stiff that its natural resonance frequencies were around 12000 hz. this keeps the 1st-4th order frequencies of the engine all below the natural frequency of the system. our reduction drive runs very smoothly. we put a glass of water on the engine mounts and the water barely moves at all. we can idle the engine down to 800 rpm, which gives a prop rpm of only 350 rpm. We cant expect a 2 stroke to idle that slowly and the rotax gearboxes are designed just the oposite, instead of being stiff they are soft, with natural frequencies that are very low, trying to keep them below the operating range of the engine. but if you run the engine slow enough you start to get some low order resonance. A belt drive will be very soft and a chain drive could be moderately stiff. topher ________________________________________________________________________________

Actually, its the cylinder configuration in conjunction with John's stated torsional loading/unloading. Some engines are much better than others but primarily because of the number of cylinders and the arrangement of those cylinders (firing order, too). Two cylinder, two cycles have a 1st order rotating unbalanced moment of 1.0, while a three cylinder's is the sqrt of 3. The second order unbalanced forces of a two cylinder are 2.0 while the three cylinder is 0. The bottom line is that the three cylinder can be in balance with the second and first order forces at the same time while the two cylinder engine will never achieve that state. The same can hold true for any engine based upon a multiple of 3. J.Baker ________________________________________________________________________________

Yah, I think you're right, up to a point, but did you read Richard Pikes' message about the effect of timing on the Rotax engines ?? I think that between the 2, we've got an answer. That message about system rigidity balancing the firing impulses makes sense too, but it's over my head, and beyond my skills. My timing will be fully adjustable, and if that doesn't do it, then she'll just have to idle fast enuf to smooth it out. Sure hope it works out to where I can idle it right down. The Vimy was quieter, smoother, and didn't try to run away. Looked neat too, with the props kind of paddling around. That was sure a good weekend.

Subject: First Solo in a FireStar
Greetings, Last Saturday Dave Rains gave me the opportunity to fly his FireStar. Although I hand flown an UtraStar a couple of years ago this was the first time I flew a Kolb Solo. The plane climbs like an elevator, after take off I felt more vertical motion then horizontal. I did some flybys over the runway before I committed to a landing. My first landing was not the greaser I had hoped for and the second one was worst. On my second landing I started swerving the left then I over corrected to the right. I almost came off the runway but I gave it some power which made the rudder respond. I loved flying Dave's Firestar so much it got me motivated into finishing my own FireStar. Today I assembled the tail feathers and got it ready for rigging the wings, will update my webpage soon. If you want to see some pictures taken Saturday morning on my first FireStar Solo please visit the URL below. I also added some video. http://home.elp.rr.com/airplane/Fun.html Regards Will Uribe building a FireStar II own a "land-o-matic" Cessna 172 El Paso, TX ________________________________________________________________________________

I frequently wore a helmet when I flew my Hummer because; 1) That's what the headset was mounted in, and 2) it had no forward overhead protection and was marginal when landing in crosswinds. If I was going flying on calm evenings and didn't plan to need a radio, then sometimes I used earplugs and left the helmet home. I feel that flying the MKIII is essentially the same as flying a Cub or Champ, would you wear a helmet in one of those? Both my two main flying buddy's have Drifters, and wear helmets at all times, but in their case, they have more of a wind problem that the Kolbs do. Helmets are great places to attach face shields. Wear what you are comfortable with. Wear what will help keep your spouse from worrying. An unworried spouse helps make a happy Kolb.

Dale, Check the wrap of the pickup wire of the Tiny Tach around the plug wire. Jerry, the guy who sold you the FireStar, had to splice the pickup wire to make it long enough. He may not have soldered the splice causing it to be erratic. I wear a helmet to block out the noise and save my ears. It also keeps the wind out of my eyes so I can see better using a full-faced shield.

Duane, A fried had a 582 on an orignal Firestar while his 377 was being rebuilt. He reported only 1200 fpm climb, and said that he couldn't use the power in level flight because of exceeding the VNE. I said "only 1200 fpm" because the 377 gave about 900 fpm. One problem that you would have is CG. Most 503 powered Firestar II's are right at the aft CG. A 582 is heavier and you would likely have to add weight in the nose. Plus, I am sure that the company doesn't want people to exceed engine recommendations.

First, thanks for the information some of you provided concerning the gearbox chatter! I guess I have to resign myself to living with the problem or looking at retrofitting to a variable timed ignition. Based on a comment awhile ago (forgot who) I'm trying synthetic gear lube in my gearbox. Couldn't find 85-140 EP in synthetic at the local auto supply store's, but the local AMSOIL dealer had it for a higher price of course. Hope it functions as well as was described. Question for anyone who might be able to help. A couple of days ago I wrote about helping a friend mount a new 447 on his old Drifter and how it idle so much smoother because of the belt drive. Well now his tack doesn't work, it pins out. His old 447 was a point ignition system and of course his new one is Ducati. So on the advice of another Kolb owner I cut the wire loop sticking out of the back of his tack. It still pins itself when running. Does he need to buy a new tach because of the Ducati ignition? I don't want him flying with out a tach. Terry K. FF #095 ________________________________________________________________________________

John , I don't mean this rude or crass at all , but what are you trying to say??? Are you wanting to promote some other material for cockpit area structure or just that nothing is safe. I think everybody understands the laws of physics to some extent that no matter what you are in if you make contact with an immoveable object at enough velocity you ARE going to die!!! Mass X Velocity = Kinetic energy and your body can only handle so much...the more the structure around you can absorb then the better your chances for living. If your promoting weaker structures to ensure that your poor family doesn't have to care for you as a vegetable then I'll take the risk and hope that I come out on the better of the stick and LIVE!!! If your promoting a flying Sherman Tank than I'm all for that too..can you make it fly on a 52 horsepower Rotax and make it take off in a couple hundred feet??? I know of an accident that really was minor by most standards that wiped the front end clear away from a Challenger ultralight 2 - seater. The rest of the structure was hardly damaged...except for the guy in it... Now I'm not knocking Challenger cause they are fine aircraft with some great qualities , but I personally don't think crash survivability is one of them. The 4130 cage doesn't mean that you can't get hurt but it will absorb a heck of a lot more kinetic energy that an aluminum tube structure which will basically snap and twist and break (limiting this discussion to the general methods and materials used in 99% of ultralights those are the choices...) 4130 on the other hand will deform a great deal before it just breaks and its tensile and compressive strength is much higher then even larger diameter aluminum tubes and hence will absorb more energy before it hits its yield point. We all accept the risk every time we get up in the morning and if your going to live life you have to accept it and get on with it. I'm paraphrasing this quote , but Orville Wright once said after being asked about a aviation-related fatality , that if you want perfect safety you better sit on the fence and watch the birds fly...but then again you could fall off the fence and break your neck!!! Sincerely, Jeremy Casey P.S. Sorry for the long post....

Me thinks you have grossly overestimated that Xwind speed. I can't picture landing a FS in much more than a 15mph Xwind component ...at least not without substantial risk of trouble. Finding another field is just too easy an alternative. Even 15mph is darn good -- that is 50% of stall speed!! Remember, with winds approaching 30+mph you should be able to settle a Kolb down vertically (or maybe even backward) wrt the ground. (I've seen windsocks standing at full attentention at 20mph windspeed.) Also, somebody mentioned landing fast and then pushing stick forward. Does keeping the tail up make sense? I've always thought it better to have the tail on the ground for the tailwheel to help keep things pointed straight ahead. I can see wanting to keep a low angle of attack so-as not to pop airborne again in a gust, but I would think the tendency to weathervane would be severe -- greater than available rudder authority as the plane slows down -- so I'd be careful about holding stick forward very long (other opinions/experience on this anyone?). I do know that I've had better luck keeping some power for prop wash over the tail even tho the idea is to slow to taxi speed. This helps a lot with controllability during the slow down, even tho all your brain wants to do is slow down and finish the thing. -Ben Ransom --- GeoR38(at)aol.com wrote: > > In a message dated 5/6/00 8:07:17 AM Eastern Daylight Time, > WingManBill2(at)aol.com writes: > > << Crab right down to before touchdown and then center her down the > runway > before touching the ground.

A chute is insurance when you need it. I would think that a helmet would be desirable for the cage cross member directly behind your head.

Your right, of course, that finding another field would be a good idea. I never said that we did these kind of things on puropse or just for fun.

He said they have had several bad incidents with major injuries caused by sling seats. I intend to use a hard shell with foam for comfort anyway. The safety may be a bonus.

I know we have talked about why the "Kolbs" or any taildragger tends to bounce down the runway with a strong headwind or crosswind. The fact that the tail is "heavy" and if you hit a little hard-the tail will drop to the ground and put your wings in flying attitude again. That is why I suggested pushing the stick a little forward into a strong headwind/crosswind. In the winds approaching 35 knots, in my experience, if you pull the stick back too soon-- you will be doing "bunny hops" down the runway and replacing your $80 landing gear. ________________________________________________________________________________

Subject: Stuff!
Morning Gang: Well, yesterday was a "red letter" day for me and Miss P'fer. After sitting quietly since 2 Jan 2000, she got noisy when we cranked her new 912S for the first time. Only adjustments to carbs prior to and after start were mechanical synchronization. Turned on the Facet fuel pump to prime the system, pulled the enricher full on, hit the starter and before she turned a couple blades the engine was running. All gauges worked (lucked out and got them all hooked up correctly). I believe this engine runs smoother, out of the box, than my old 912. My initial pitch setting was 14 deg on the 72 inch 3 blade fast taper Warp Drive. I could only turn 5100 rpm static, so we may be a tad heavy on pitch. I may wait to do a pitch change after I do the first test flight. The engine may loosen up enough to pick up another 100 or 200 rpm. If not, I still have plenty power to fly and I will be better educated on how much pitch change is required. The 912S is idling very smoothly at 1600 rpm. There are no flat spots, that I can tell, between idle and full throttle. This engine seems to run somewhat hotter than the old 912, which is good. The 912 usually ran too cool with oil cooler hooked up and 50/50 antifreeze. The real truth in temps will come once we are flying and, of course, when we encounter our first cool weather in Canada and Alaska. We plan to have an oil cooler cover that will be easy to install and remove when required. Nope, have to do that on the ground with the blade stopped. :-) I did not measure the prop clearance to boom tube, but looks like about 1.5 inches, running a two inch prop extension. Got to go back and remove two AN "T" fuel fittings that are leaking. I did not use thread sealer and some of the hose barb fittings are oozing a little. Coolant and oil hoses are all A-OK as of now. My fuel sight gauge seems to be working. Increased visability of the lower range, down to .5 gal will be a big help and comfort in the future. I also have a mark for 2.5 gal, then 5 gal marks up to 25 gal. Will be another day or two before we fly for the first time with the new engine. As anxious as I am to see how the new setup will perform, I have to discipline myself to finish all the little things that need to be done. If I don't, it is even harder to get them accomplished after I begin flying. BTW: The new oversized rudder trim tab looks like it will probably do the job. During static run up yesterday, the rudder was really deflecting to the right. During updating I discovered part of my yaw trim problem. For some reason I leveled the aircraft, using a bubble level. Low and behold, the slip/skid indicator was about 1/3 bubble out to the right. Since I went to a much larger trim tab, I can now, most likely, move the vertical stabilizer back to the centered position where it belongs, rather than being bent in a curve to the left. Got a lot of testing, checking, and flying to do in the next six weeks before I depart for Oshkosh via Point Barrow, Alaska. Times a wasting and I will not depart until I am satisfied that the airplane and I are completely ready to go. Does anyone have a source for US, Alaska, and Canadian Sectionals, other than Sporty's and AOPA (my membership has expired)?

This definition of a crosswind wheel landing is the best yet with one exception. A wheel landing in a cross wind doen't require any lifting of the tail other than to lessen the back pressure slightly so as to let the airplane stay on the ground as airspeed decreases allowing the plane to settle on both main gear and then the tail.

Topher and Group, Maybe Kolbs are not like Citabrias on landing. I have been landing Firestars on a 500 ft grass strip for the last 4 or 5 years. The only time I ever ran out of rudder was on takeoff. And that only happened when I was new to a Firestar and a little slow to get on the left rudder on taakoff, conbimed with a crosswind. I land three point on grass and crosswinds have just not been a factor. My technique is to crab until just before touchdown. But even when the plane quits flying earlier than I expect, the plane has been easy to straighten out with the rudder. The plane has always been easy to control on grass. Crosswind landings on pavement are a different story and I can understand why people are concerned about them. My limit for crosswind landing on grass is easily over 15 mph, probably 20 to 25 mph. My limit for a Quicksilver MX was 15 mph, and my Quicksilver Sprint handled about 20. Here is a suggestion for builders. Make sure that the rudder is not smaller than the plans. The rudder on my Firestar to is just slightly larger. I did not want to error on the small side.

I'm the "new man on the site" with the 912. What you read earlier on Kolb web site was the start of a letter that I didn't finish and it was accidentally sent. I'm new at this! My wife's still laughing at me. I was sitting here reading my posting with a red face 'cause I didn't realize I had sent it. Makes me feel very computer illiterate! Oh well, at least I can fly. What I was going to address was the 912UL vs. 912S. From the postings I've read, I saw no mention of fuel consumption. I can get on my 912UL 2 1/2 t 3 gallons per hour. With the 912S, I wonder how much fuel that would burn at the same speed. Having more horsepower, I'm sure you could cruise at a lower rpm. It's something to look into if you're thinking of the 912S.

I tried the same thing a few years ago because I had an alumimun tank with a sight tube. 1. Like you said they were hard to find-impossible to find. 2.

Gas eats them both up-they sink in a few days and generally make a mess. Best you can do with a sight tube is use a clear tube and if your not using oil injection- you can see the gas/oil "pretty good till the sight tube gets old. One other suggestion is to put a few drops of coloring in the gas, like drafting ink-mostly carbon based anyway- a little goes along way. PS. I don't use a tank I can't see through any more-think I hold the record for running out of gas. The sight tube only works when your plane is flying at the same level as your original calibration. Flying on long trips not knowing if you have 2 gallons or 1/2 gallon of gas can be stressful!

Lar and Gang: I use the protractor that comes with the Warp Drive. Since I am going to put the same degree of pitch in all three blades, I need to get a zero and a "K" factor. Zero degrees is the face of the prop hub. Rotate the center ring with the bubble level until the bubble is between the lines. Then read what the angle is, + or - a number of degrees. Now I use a level to get the blade horizontal, add or subtract the 14 degrees (or whatever pitch you want to pull in) to the "K" factor, twist the blade to level the bubble. Do the same to the other two blades, then go back and double check my work. I have been using Tygon tubing for fuel site gauges since my Firestar days. That Tygon was yellow. The new Tygon I now have is clear. Never needed any "little colored balls" to see how much fuel I had, even at night. Absolutely no problem during daylight hours or dark. At night I hit the gauge with my minimag flash light. Fuel level stands right out. BTW: Even though my MK III is signed off to fly at night, I do not make it a habit to go out and toot around the area at night for funsies. Usually get to log night flight when I get caught out on cross countries. It is nice to have the capability, but not recommended to fly single engine experimental at night on a regular basis. When I am XC'ing I have a minimag flahlight with red lense and one with white lense. It helps to have some way to read sectional and supplements. Also a back up if panel lights go belly up. There is also a good chance loosing the single landing light. NO, I don't use the minimags for backup landing lights. :-) They have a very short life. I installed a new halogen landing light bulb for the trip to Point Barrow. Haven't had a chance to fly with it yet, but tonight it seemed brighter than the old one and it is supposed to last longer.

John Jung, i would be less worried about running out of rudder then geting flipped up and cetch a wing tip when your just at stall speed and a big crosswind gust comes along. the lack of dihedral of the kolbs is probably a great help here compared to the citabria and most other planes. I have never run out of rudder but I have had to choose between staying in line with the runway and keeping a wing down. if a wing starts to lift you stomp on the rudder to get it down, which points you off the runway. I've been tought that i'm a bit better off wheel landing in tough winds but I am a very low time pilot and if you have the skill to full stall in a crosswind then have at it.

Does keeping the tail up make sense? i asked a cfi certified flight instructor that very question in a training question last week his reply was that in either a full stall landing or a wheel landing you still needed rudder authority in order to keep it straight and not ground loop. he also mentioned the use of breaking once the main wheels were firmly planted on the ground (wheel landing) to assist the rudder in maintaining the authority needed to keep it straight. i think that one would take a lot of practice. boyd ________________________________________________________________________________

Well Possum, I'd still like to know how that out of gas situation too far from the airport worked out in your video. Didja get killed ?? That was a real Hitchcock ending. Never knew you to worry about gas anyway. Trees either. Seem to remember you turning a FireStar into a submarine one time ?? Trees again ?? Gas ?? Didja ever send that guy the pic of your "SwimStar ??" Seriously, actually I did find the little gas balls, I think at Wag-Aero if memory serves, but they're too big for our lines. I guess they're treated with something, cause they told me not to try cutting them up. Also saw something in a mag a long time ago, about making a strip of diagonals, like a long row of chevrons to put behind the tube. Refraction shows the gas right up. Don't think I'll worry over-much about it anymore, if John's never had a problem, I doubt if I will. The ole eyeballs still work pretty good, and I - Most Definitely - don't plan on any night flying.

Subject: Fuel Tanks
Date: May 11, 2000
All this talk about fuel lines, etc. got me to thinking, and it hurts, so I just gotta talk this out. I believe quite a few people have ordered the 15 or 16 gal aluminum fuel tank for their Mk III's, as I did. ( Does anyone know for sure just what they do hold ?? ) Can't remember if I said this a couple of yrs. ago or not, so here we go again. Every solid mounted aluminum tank I've ever seen has been cracked. That's why I've seen them - they're out for repairs, and the thought doesn't fill me with confidence. When it came time to mount mine, I ordered 1 sq. ft. of 1/8" gum rubber from McMaster-Carr, along with a short piece of 5/8" surgical tubing. Cut strips of gum rubber, and glued them to the frame rails that the tank sits on, and to the mounting tabs. Then, carefully, drilled out the mounting bolt holes on the frame and on the tank. It's awkward, and doesn't look real pretty, but that's OK. Took 3/16" bolts, and put on each, a washer, a 3/4" piece of the tubing, another washer, and a lock nut. Installed one in each drilled out hole, and tightened them down, so they acted like the expander cork in a thermos bottle. There's 8 of those bolts, and along with the gum rubber, let the tank move just a little, and then STOP it solid. I don't want it coming loose if I hit something. Hopefully all this will eliminate any cracking of the tank. If not, it won't be from lack of trying. If anyone's interested, I have one 1/2 assed pic of the whole thing. If there's enuf interest, I'll take some better ones. Guess maybe I should anyway. Manana. Cautious Lar. ________________________________________________________________________________

As I slow down to taxiing speed I've used the practice of keeping the stick pushed in the same direction as the wind (to avoid a flip over from incorrect aileron or elevator position). The most Xwind I've landed in is about 12mph 90deg. I had never really known that the correct idea for stronger Xwind landings is to do a wheel landing.

My experience with Jim and Dondi has also been > GREAT ! ! ! Mekky Lar. I use a 3M mask when using PolyFiber Products. For MEK one does'nt need anything like what is required for the urethane coatings, only something to remove the vapors. This is NOT the paper filter type of mask used for cold weather breathing, or for surgical purposes. Rather it is the simple activated charcoal type of mask. It really eliminates the "smell" of MEK almost entirely. While MEK exposure CAN be a problem, it is not at such a level that one should accept less in performance of a product in order to avoid it. Do the water based coatings "less in performance"? That remains to be seen. PolyFiber has been around since the late '60s, almost 35 years with many thousands of aircraft covered and has a well established track record. The new kid on the block has been around in significant numbers for less than a decade. In reality it is sold mainly on the "environment". Age testing you say? I am sure they have done artificial aging testing (note that I do not use the phrase "accellerated ageing - I hate those words}. However, I have done a very large amount of testing to attempt to predict how well something is going to age. Such tests are better than nothing, but are full of potential misleading factors. In short, these new coatings might very well turn out to be great. Always happy to see new ideas that prove to be breakthroughs.

I placed mine just to the right of my right shoulder app 4 inches in front of the tanks. I quickly found it worked will on the ground but for a quick look while flying these old eyes couldn't make out the fuel level. I tried spiral wrapping the tube with thin instrument marking tape with some improvement. Finally I found a small cork stopper that I have trimmed down in size so that it fits the sight tube but is too large to pass through the T fittings that connect the tube to the fuel system.

Subject: more cross wind landing thoughts
Hi Kolbers, During the 1970s, while I managed a one runway 2100' grass strip airport, I watched and taught a lot of cross wind stuff. When the approach was arranged such that the ground roll could be diagonally into the wind, the pilot could produce the slowest landing speed and shortest ground roll. In fact with 30 Knot winds occasionally Cubs and Cessna 140s would be so diagonal that they were nearly crossways to the runway, as has been recommended by some of our other contributors. Of course with this line of thinking, the width of the runway, and the condition of the space on the 'role out' side of the runway become important considerations. Power management during approach, touchdown, and role out, also was a key factor in making this a comfortable, safe, operation. With cross wind gear, and on icy runways one must continue to yaw, more and more, into the wind during the role out or one is pushed off the other side of the runway by the winds. As the speed decreases, the into the wind crab angle needs to increase. It is safe to stop facing directly into the wind. I expect that if I flew the current Kolb, with the source of thrust above the wing, I would do more NEW learning. I have had some experience flying the UltraStar #306 (which I built) back in the mid 1980s.

My understanding of the wheel landing is that one has more control in a adverse landing situation. Since the pilot still has speed when landing it is possible to simply apply additional power with the proper rudder and aileron corrections and just take off thereby avoiding a possible ground loop. With a full stall landing control of the plane is subject to the available rudder and aileron depending on the speed and direction of the wind. I always wheel land and have landed with 15 kts. @ 45 degress with no problems. I believe Ben's 12 @ 90 deg is still stronger and kolbs seem to handle that just fine. The other reason I paractice and do wheel landings is to save the landing gear. So far it has worked.

Which really means that each set of wheels has had its own set of bearings, ie. 6 total plus one new set for the last set of bigger wheels. I found that the cheapos that came with the kit in 1992 were very cheap and so I befriended the Bearings inc. guy locally and put in new ones there after no more than 10 landings (I'm guessing). Crosswinds have probably been a contributor to the degradation of my chronic main bearing syndrome, but a more probable deleterious aspect is the slight bending of the gear legs, causing a partial side thrust on the main bearings. My increase in weight has also hastened the life sapping forces on the bearings as well, I assume. I went from 185 to 220 and am back down to 207....gotta get back to 185!!!

Homer designed his airplanes with most of the weight on the main gear to make them easier to ground handle and less likely to ground loop. Then there are people like me who change his design to gain somethings that are lost in making the Kolbs easy to fly. I pushed the main gear 8 inches forward on my MK III. I felt I needed more weight on the tailwheel to keep from nosing over in rough field, soft field, no field high weeds and brush conditions. By doing this I sacrificed the gentle taxi/landing characteristics of the standard design. Now I have a heavy pendalum sticking way out behind me. The track of the main gear is aprx 72 inches or 84, CRS. This keeps the aircraft level during ground loops, like my initial landing at Oshkosh 98. Lost the right tailwheel spring somewhere between taking off from Joliet, IL, and landing at Oshkosh. A blustery 90 degree crosswind from the west. Could not understand why I was no longer in control of my airplane after touchdown. :-) Had I known, I could have gotten down hard on the right brake and maybe, just maybe saved it.

In the traditional tail wheel (engine up front) airplanes, 'managing power' would manage tail surface responsiveness and, that increase in ground effect under the high wing, (especially with flaps extended), resulting in a stall speed for landing that was several miles per hour slower then with the propeller turning at idle speed. John h contributed very valuable information about 'main gear location.' The early Cessna 140s, also, had a near center of gravity, main gear location, but users were continually 'nosing over' so they moved the gear forward on the later models by about 4 inches to solve the problem for the normal user. My guess is that 'wheel landings' would then be a little more vulnerable to 'porposing'. In talking with the Cessna factory people and experimenting, we found that with proper management of power (prop blast over the tail surfaces and under wings), we could land a Cessna 140 with brakes engaged and skid to a stop, even on pavement.

If you don't stay ahead of your wheel landing in my MKIII, you will certainly pop up as the mains hit and the tail comes down. Your second point sounds like you are describing a normal landing in my MK III. There is no indication to nose over on all surfaces except dry pavement. Can lock up on wet pavement with not problem, but dry will get the tail up. Normally do not make wheel landings because of ease in getting into a pop up situation. However, come in with a little power and she will fly or settle back down and stop flying. Take care, john h PS: Spent all day yesterday working on parachute installation in center section. Tends to wear down my poor old brain trying to think far enough ahead as I engineer the project. The center section on the MK III is unique, to install it has to be clean on the bottom. My parachute installation will have the the BRS rocket laucher protruding thru the bottom into the cockpit near the bulkhead behind the left seat (copilot seat in my MK III). So, I have to install the rocket after the parachute is installed in the center section and after the center section is installed on the aircraft. However, since I lowered the rocket 4 inches, I will not have the rocket protruding out the top of the center section. The parachute egress will be thru a piece of black "hair cell" plastic sheet (provided by BRS) that is 22"X16", secured with alum pop rivets and sealed with silicone seal. You can tell BRS what size you want. I had them send me two pieces in case I screwed up one. Now I have a BRS 1050 Softpack, completely inclosed, with a 6 year repack and 12 rocket replacement. Hopefully will not have to worry about keeping the water out, resealing around rocket and deployment door as I did with the old 2d Chantz Chute. ________________________________________________________________________________

Date: May 13, 2000
The closest thing to an ultralight that I've flown is a J-3 Cub. The procedure that was taught for cross-wind landings was to slip it in straight down the runway at a little hotter speed, then as soon as a wheel (or wheels) touch down push the stick slightly forward to "plant" the wheels and to make sure you have killed the wing lift. Then keep pushing the stick forward as you slow down until the tail cannot be kept up. Then the stick is pulled completely back to stick the tail wheel for control. Don't know how this would work for a Kolb. Also, the fuel indicator in a Cub is a wire produding through the cas cap with a cork float on the bottom. The wire goes down as the fuel is used. The cork seems to last forever. Rody (Building a Mark III) ________________________________________________________________________________

Big Lar and Gang: I forgot to mention when I was talking about my fuel site gauge, but I use 3/8 ID clear Tygon, not 1/4 ID. For fittings I use the old Kolb fuel tank "push in" fittings that were installed with a large rubber gromet. The big end of the fittings fits the 3/8 ID tubing nicely, the 1/4 end of fitting goes thru alum or steel tangs in the bulkhead, top and bottom. The fuel line is pushed on the fitting after it is pushed thru the bulkhead, held in place with a SS hose clamp. With this set up you will not need "little colored balls", fish bobbers, artificial snow, or Easter egg dye. You will be able to see the fuel level, no sweat GI.

None of the above failures were of the o/v nature & >none damaged any avionics. Agreed . . . and MOST of the externally regulated alternator hardware out there is specific to aircraft and designed/certified 20-30 years ago. Check the service difficulty reports using keyword "alternator" and then filter for single engine aircraft . . . Everything that might be deduced in the way of alternator failures happens every month in a TC aircraft . . . "casting broke, thru-bolts stripped, brushes worn out, windings burned, bearings siezed, diodes shorted, etc. etc." FBO's love 'em . . . regulated job security well into the new century. On the other hand, when you take a brand new, Nipon-Dienso, 40 or 60 amp alternator, disassemble for modification to run external regulation, balance the rotor to about 10x tighter specs than they come out of the factory and re-assemble with due care, you end up with an alternator that runs well for a very long time. I have first hand knowledge of 2,000+ such alternators sold over the last 8 years . . . not one has returned for wear-out or repair. It's the difference between a 1990's product and a 1960's product. >I don't use o/v protection, but if I did, it would probably be the very >simple zener/fuse arrangement. I'm sure Bob's solid state system is more >sophisticated & works better, but as the guy used to write in BYTE >Magazine, 'Better is the enemy of good enough.' The zener fuse combo was certified onto early American and subsequently Grumman-American aircraft. It's a sort of poor-man's crowbar ov protection scheme. When I first heard of it, I was skeptical. It has been about 15 years since I brass-boarded this system onto an alternator-battery system in the lab. Here's what I found. Proper operation of the system depended heavily on two things. (1) A fuse (fast acting) had to be used upstream of the zener and (2) the zener had to be a 1W glass encapsulated device - p/n 1N4745. It works like this: In an ov condition, the zener tries its best to keep the bus voltage from rising above 16 volts. In so doing, internal disipation rises well above the diode's 1W rating and it commits electronic suicide by becoming a dead short. The resulting short opens the fuse and corrals the runaway alternator. Over the years, folk who did not understand the "balance of power" implicit the this design made well meaning-changes to this scheme with the unintended consequences of degrading performance or even making the system ineffectual. Common errors include: (1) Replace pesky fuse with a real circuit breaker: Opening times for breakers vs. fuses is 10x to 50x longer. The slow response of the breaker stresses the zener to explosive destruction. The altenrator runaway continues unabated. (2) Substituted any ol zener with the number "1N4745" printed on it: Plastic parts were unable to withstand the rapid onset of heat dissipation and explosive destruction of the zener results. The runaway continues unabated. (3) Substitute a really husky 16 volt zener for the itty- bitty 1W device. This change was often combined with a change from fuse to circuit breaker. The general idea was to make the protection scheme "reusable" . . . no fuses -or- zeners to replace: The general effect of this modification was to push the time-constant for tripping OV protection out by hundreds of milliseconds to perhaps several seconds. Contemporary OV protection is designed to react to a step from 14-20 volts on the bus in 50 milliseconds or less. >My personal feeling about external regulators & o/v protection is this: >Once I reach a certain (hard to define) comfort level about the >reliability of a system, I'd rather not add failure modes. Over-voltage >type failures in self-regulated alternators seem to be so rare that you >hear about every one. Generator/regulator & alt/regulator failures are >so common that they are treated like dry vac pump failures, you know >they are going to happen sometime in the near future. No argument about comfort levels . . . I'll suggest that the greatest body of experience with aircraft alternators comes from the world of certified aircraft. My best recommendation is to see what's happening with true state-of-the art designs and fabrication techniques. There's a mistaken perception that the certified aircraft world is benefiting from the advance of technologies in all respects . . . I'll suggest it happens only in area of things you bolt into holes on the instrument panel. Stuff under the cowl has evolved very slowly if at all in 50 years or so that have passed since the first generator was bolted to a single engine airplane. If you want to know what a modern alternator can really do for you, you'll have to limit your observations to the real leading edge of aviation technologies . . . check out the flight line at OSH.

I'll worry about the repack when the time comes. BRS uses a hydraulic press, or something similar to pack the 1050 and larger softpacks. If we wanted to invest in the machine, then Brother Jim could repack for me. Not sure what the press cost. Got the BRS installed and center section on the airplane. What a "first time" job. Next time I have to do it I will know how. This first installation was a lot of trial and error, sitting and thinking, and scratching my head. Will take some getting used to the bottom of the rocket launcher inside the cockpit, but after installation I sat in the left seat and it did not interfere with my normal sitting position.

Doesn't matter, little varmint loves my airplane and everything in it. I hope so anyhow, cause I left him some rat bait at the tailwheel, where I think he is getting inside up thru the boom tube.

I don't wish to give the wrong impression about Poly Fiber. It is a system that works and has been proven but when covering with the Poly Fiber process I had a constant headach, even when working with the shop doors wide open. With AFS I did most of my covering this past winter in my heated shop with the doors closed and the heat at 72 degrees using an open flame gas heater. On several weekends I worked two full days gluing and got no headach. I did have a little glue stuck to my fingers and cloths but the glue comes off the fingers rather easy. The cloths are a different story. Also I can pait using a normal carbon based mask instead of rebreathing equipment and get a nice shine. The one draw back to AFS is that it doesn't work as fast because of the water, but I am not in a hurry. Vic ________________________________________________________________________________

It was new territory for me but with the help and advice of my fellow Rotax owners at the airport things went pretty well. Here are some of the things I learned during this work: 1/ Start by re-reading Stratman on Care and Feeding of Rotax engines, 2/ Consult someone who knows about this job at your Rotax parts supplier and get all the right gaskets you will need before you start. 3/ Special tools required include a good torque wrench, picks to clean the ring gooves, and Scotchbright to remove carbon from the piston tops and rings. Rotax makes a cylinder alignment tool (~$20) which would be a help during reassembly and a wrist pin and bearing extractor which is required if the pistons are to be removed (nice option but I did not do it this time). 3/ Clean the outside of the engine before you start to keep loose dirt from falling into the crankcase when you remove the cylinders. 4/ Note and or mark all parts as they are removed. It is critically important that they all go back in exactly the same place they came from and with the same side up! 5/ Carefully examine all mating surfaces and check the torque on the nuts and bolts being removed. You are looking for signs of leakage and or potential causes. 6/ Keeping the carbon being chipped off of the piston and rings from falling into and contaminating the crankcase is a problem. I used clean/oiled shop rags and that seemed to work. As a former ground support equipment designer I longed for some neat little flexible skirts that would fit snug around the connecting rods and extend out to the studs or drape over the side of the engine with the studs removed. I gave up the idea because I did not want my engine sitting open while I went through a design/test/fabrication effort. 7/ Plan to spend some time carefully scraping carbon from the rings and grooves. The objective is to get it all off without scratching any machined surfaces. 8/ The really delux job would include removing the pistons and having them cleaned in a shop that has a cleaning tank but that involves removing the wrist pins and cageless needle bearings. Without the Special Rotax removal tool there is a fair possibility of dropping one or more of those little bearings into the crankcase followed by some extreme anguish. The snap rings that hold the wristpins in place are also subject to damage and or loss. 9/ When the pistons and rings are really clean and the rings are back where they came from it's clean up time. Removing the oiled rags from around the piston skirts requires that extreme care be used to keep any falling particals from contaminating the crankcase. 10/ Caution... the gasket at the base of the cylinder can be installed backwards, restricting the passageway from the crankcase to the inlet ports. 11/ Reassembly was fairly easy although while fitting the cylinders over the pistons I did used some special explitives that are not part of my normal vocabulary, 12/ Align the intake ports before tightening the head bolts. Use the Rotax tool or you can probably get by with a good straight edge if you are careful. 14/ Have a pal check all your torques. In the aerospace bussiness every torque value is witnessed by a Quality Control Inspector and signed off in a log. It's worth the effort. 15/ With all due confidence I am staying close to home base for the next few hours just to make sure all's well before I venture out on any trips. 16/ Retorque heads after 2 hours (per Rotax manual), compression check while you are at it (per me).

Subject: Coolant pressure problems? Try a lower-pressure cap!
Coolant over-pressure on the 582 with stock dual radiator setup was a problem for me last year (peak pressures of 18 psi. were typically recorded on a liquid-filled hardline stainless gauge during first half-hour of every flight, despite the use of a 13 lbs. cap!) . After trying a few things, and testing the present solution for 10 hours, I am convinced I have it licked. Now my system runs 7-8 lbs pressure or less, and retains the expansion-tank feature as designed. The solution was to fit a lower pressure-rated radiator pressure cap, and since I could not find one to buy, I modified the stock cap to maintain the lower pressure. It is as simple as bending the spring. I made a fancy spring-pressure gauge out of a torque-wrench and carefully measured the force the stock cap spring was making (the values I measured have no standard units because the setup used was only for relative comparison before and after modificatoin, so I cannot tell you what the spring force was). I then bent the spring little by little to lower the measured value to 75 % of what it was originally. That's it. Works great, home-built 7 lbs cap. Of course, I switched to the silicate-free and phosphate-free anti freeze this spring, and as always it is mixed with only distilled water. So maybe, with a little luck, we can say goodbye to the potential for RV shaft seal problems... Do we have everyone coinvinced to monitor their coolant pressure yet?

Sounds reasonabubble. I had kind of thought of that anyway, after reading a suggestion by Tim Hrib, but in the meantime, I'll be taking John's advice about the larger dia tubing for the sight gauge. That makes sense too. I'm also gonna crawl under that thing, and look at the gum rubber tank mounts I made. Dell Vinal made a good point about the longevity of that stuff.

Big Lar: I second Dell's recommendation on surgical rubber. Not much longevity. I used some nice heavy wall heater hose, split to fit the tubes the tank sits on. Stuck em on with a little "gorrila snot". Been on there 9 years now without a problem. Got to have something with some resilience and tuff enuff to withstand the pressure of the weight of the fuel (times and the G's being pulled) plus the pressure exerted by the fuel tank straps.

Subject: Test Flight
Mornin Gang: About 1800 hours yesterday, Miss P'fer and I went for our first flight with the new 912S and 6 foot Warp Drive. WOW! First thing I noticed was I had way too much rudder trim with my new "oversized trim tab." Instead of right pedal, now I have to used left pedal. It is almost like the engine turns opposite from the 912. First I will move the vertical stabilizer back to the orginal centered position. If that is not enough, then I will cut 1/3 of the trim tab off. I had to use .040 alum to make it stiff enough to work properly. I do not think I can take some of the bend out of it without damaging the rudder. I certainly do not want to create anymore work for myself. I knew the prop was pitched a little heavy, would only turn 5200 static. But in the air it would only turn a little over 5000 strainght and level, about 5100-5200 climbing from 70 mph down to 40 mph. Climb rate was a consistent 1500 fpm with 20 gals of fuel on board. A quick ASI/Static Pressure adjustment got the ASI calibrated. 80 mph indicated is actually 79 mph average speed across the ground measured in opposite directions. Right off there is an overall sense that the 912S is a lot more engine than the 912. I got this sensation in sound, feel (seems much smoother), and throttle response (lots of power even though the engine is way over pitched). Can't wait to get the prop dialed in so the engine is really doing its thing. I want to see 5500 rpm WOT straight and level flight. I may be like John Russell and his new 912S/Sling Shot. He's still not ready to see WOT straight and level speeds. :-) Everything worked! All gauges, lights, intercom/radio, switches, did what they were supposed to do. That is a relief after changing out all that stuff. On the way to Gantt International Airport to get Miss P'fer (P fer plane) dialed in and ready to fly to Moon Town Airport Flyin (east of Huntsville, Alabama) Friday or Saturday, then Sunday on over to Chesnut Knolls Air Foundation for a few days to do a little work on the MK III.

Hi Duane An excellent detailed post! I use almost the same procedure but would add that instead of using the Rotax cylinder alignment tool, I remove the exhaust manifold from the muffler assembly and bolt it back onto the cylinders (without the gasket)before tightening the cylinder bolts. This ensures that if there is a small misalignment in the exhaust manifold faces, I do not build in any high stresses when I remove the manifold and replace the exhaust gasket. It works for me - so far I have not had an exhaust manifold crack in 130 Hours. Best regards, Clive.

Evening Gang: I love it when daylight savings time comes around, it gets warm, and I can fly and play around the air strip til 8 or 9 o'clock. Today I respositioned the vertical stabilizer back to the original centered position. That helped the left yaw problem a little, but not enough. Do not recommend trying to offset adverse yaw by displacing leading edge of vert stab. It is not that effective and puts stress and a bending moment on vert stab. After I landed I removed the rudder trim tab (attached with alum fabric rivets). Will cut 1/3 off it, now 22 inches down to a little over 15 inches, and try again tomorrow. Pulled 1 deg of pitch out of the Warp Drive, down from 14 deg to 13 deg. Increased rpm on climb out from 5000 to 5200 rpm, straight and level WOT from 5200 to 5400 rpm, indicating 97 to 98 mph. The MK III is so draggy it is uncomfortable to fly for long over 85 or 90 mph depending on how smooth or turbulent the air is. We are going to fabricate a windshield fairing for my MK III similar to the one on the MK III Extra. This may help streamline some of the air going to the prop and overcome the dead air space between the windshield and leading edge of the wing. One of these days I am going to take a lot of the bow out of the doors and rear quarter windows. This should also clean up air flow. The way the airplane is set up now it will cruise 87 to 88 mph at 5000 rpm. Tomorrow will take another deg of pitch out of the Warp Drive, down to 12 deg. This should increase climb rpm to 5400, and WOT straight and level rpm to 5600. By staying with this pitch and rpm now in hot weather, when I get into colder weather I should be right in the ball park. During the 1994 flight I did not take this into consideration. When I got into cold weather, especially above the Arctic Circle, I was down on rpm. Instead of climbing at 5300 it was down to 5000 to 5100 rpm. This makes a lot of difference and can make or break you in some circumstances. I reconfigured my the fuel site gauge. Now I am indicating down to the last three gals. At that point I have it marked in red, my "30 minute warning fuel light." I have flown the new eng 2 hours and am still getting accustomed to the larger prop and eng. I think when I get the trim and rpm dialed in correctly, the aircraft will start feeling more familiar and comfortable. Temperatures are running much warmer with this eng compared to the 912. This eng also seems to warm up much quicker. Maybe I will not have the cold weather problems with this one I had with the old one. The eng seems to be dialed in correctly. I actuated the enricher at cruise, immediately lost rpm. If the eng is running real close to over lean, by opening the enricher eng rpm will increase about 200 rpm.

Hi Bii I know you wrote this to John, but I would like to jump in with a comment. I have a MK III with a 912. I first had the vertical stab centered and a trim tab on the rudder and it flew real well but at around 5000 rpm the leading edge of the vertical stab would vibrate enough that you could feel it. I was concerned about metal fatigue and something coming apart eventually. I saw the offset vertical stab on John's plane at Sun-n-Fun and I thought it might help the trim and the vibration by putting tension on the vertical stab leading edge, so I offset it. It did eliminate the vibration but I could tell no difference in the trim. I still have the same trim tab on my rudder. For what it's worth.

Bii Futrell Bill and Gang: I had adverse yaw on the MK III with the 582 to the right and the 912 to the left. I waited on the factory to do some experimenting with the leading edge of the vertical stabilizer. I wanted them to drill all those extra holes in their tailboom testing different locations, not mine. About two years ago I gave up, bit the bullet, and started drilling out rivets and moving the leading edge of the vert stab. I tried in two locations, about 3/4 inch left and finally as far to the left as I thought I could safely bend it, 1 3/8 inches. I discovered several things: 1. My tests proved this modification was not effective. 2. A rudder trim tab has much more trim authority. I am not familiar with the MK III Extra, but on my airplane the vertical stabilizer is bent in a bow shape in order to get the leading edge moved to the left. To do it right the tail post would have to be fabricated with the socket for the lower tube of the vert stab oriented to the left for the off set. That would keep the vert stab in a straight plane, giving more trim authority. I do not know if that is the case with the Extra. Recommend you seek advice from The New Kolb Aircraft. The 21.75" X 3" tab bent 30 deg is too much trim. I will cut it down to 14.75" X 3" and test again. Most likely I will stay this dimension since I do not want to drill out anymore rivets, even though it is easy to drill the alum fabric rivets. I use a 2" lip to attach the trim tab to the ribs on left side of rudder. Take care, john h ________________________________________________________________________________

____ From: RWilliJill(at)aol.com Subject: Kolb-List: Stits poly Fiber Hello fellow builders I got a question that I wish someone would clear up for me concerning the weight of the stits poly fiber fabric. Do they still manufacture the 1.6 oz fabric or are we allowed to use the 1.7 oz? I thought I had read somewhere that the 1.7 oz was more prone to bowing the framework due to needing to be shrunk more. Sure wish someone could set me straight. Ron W. Hi Ron & Kolbers! Some are using 2.7 oz. fabric on the wings, and some are using it on everything (cage, controls, stabs, & wings). The shrinking of all weights of fabric is controllable by shrinking to 250 degrees, then shrinking in 25 degree increments. You can use any weight you want, with very little weight penalty, and a very large increase in puncture strength, longevity, etc. The difference between 1.7 oz., and 2.7 oz. for an entire flying machine is only about 2.5 lbs., & the stronger fabric is really worth it when going into rough fields (grass, gravel, hay, tundra, etc.) Or when you leave a seatbelt hanging out......... Give us a call, & we'll answer any questions you might have about this. We have plenty of 1.6 oz., 1.7 oz., 2.7 oz., and 3.4 oz. fabric available. By the way, we have enlisted a new and FANTASTIC web manager, & will have our webpage on line in about a month, so we will be looking for pictures of your projects (both under construction, and complete) to put on the site!

Subject: Re: sling seat comfort
Tim and group, Here is what I did to improve the comfort of the Firestar sling seat. I added a foam pad for lumbar support. They are available at stores like Target for about $10.00. Then to hold the lumbar support in position, I attached it to a padded car seat. It was like a "night and day" difference. I could only stand the original seat for about an hour. The modified seat was so comfortable, that I could fly the tank out, about 1 hour and 45 minutes, and still be comfortable. I just wish that my current Firestar II was as comfortable.

The AFS paint is not water based but is water born. Don't ask me to explain the difference. It is a two part paint and when it cures the water is all gone and the paint no longer reacts with water. ________________________________________________________________________________

Subject: Final Flight Test MK III/912S
Good Evening Gang: Well, I finally got everything dialed in the way me and the airplane wanted them. Vertical stabilizer centered, rudder trim tab 3X15.75" with a two inch lip to attach to rudder ribs, she now flies with neutral rudder for the first time. Almost seems unnatural to fly this airplane without putting in a lot of right rudder, and then the previous two flights I had to input mucho left rudder. Pulled another degree of pitch out of the 72" Warp Drive (now at 12 deg). She climbs at 5300 to 5400 rpm, 1500 to 2000 fpm, 40 to 70 mph. Straight and level WOT she turns 5600 rpm and 98 mph. 5000 rpm equals about 88 mph, and 4800 rpm gives up 85 mph. The ASI has been calibrated to within 1 mph at 80 mph indicated. Miss P'fer now flies like my old airplane. I have to admit I was really uncomfortable the way the flew on the first two days of testing. Yukky! Didn't like it. But now, she flies like a Kolb. You can stand her on her tail at 45 mph and climb damn near straight up. Never quits climbing. Not bad for an airplane that weighs well over 600 lbs empty. I am now happy with my old airplane once again. Friday I am flying to Moon Town Airport Flyin east of Huntsville, Alabama. Will depart Moon Town for Chesnut Knolls Air Foundation Sunday. Will be at the Kolb Factory for several days, then return to hauck's holler, Titus, Alabama. This XC will help me get better acquainted with the new setup under actual XC conditions. Should be able to narrow down fuel burn plus learn a lot about how the new engine is going to perform on the long haul. Hopefully will get a shot or two at Pucker Patch International Airport, Kentucky. Will not be happy until I have been into this one way in, one way out air strip in the Kentucky mountains, home of Howard Ping. If you haven't seen his airstrip and airplane, it is at: http://www.hyperaction.net/hping/ Hyperaction is an apt discription of Pucker Patch, which BTW is about 12 miles west of Chesnut Knolls Air Foundation. Put a lot of hours in Miss P'fer upgrading engine and systems. A lot more than I ever thought I would. But when I can get her to fly the way I want her to, it is worth every minute. I am impressed with my new airplane, serial number: M3-011, N101AB, 4.0 hours on the 912S and 1,349.9 on the airframe.
