If not, I don't know why you feel this way. Maybe I have missed something, but as a list member for almost 10 years, I would like to add some perspective: Without a doubt, you contribute more value to this list than any other member. You not only have the most experience, but it very generous of you to spend so much time sharing with the list. This is the time of year (winter) that we tend to be more easily irritated. You post the most, so if someone is going to get irritated by the list, you are more likely the source. You tend to defend your ideas so strongly that others can feel like they are being told that they are wrong. By "strongly", I mean repeating yourself, especially repeating how many Kolb hours you have. Recently, it appeared that a newer member replyed to the list, quoting something that was said about you off-list. If this is what happened, you have a right to be upset. But it did not lower my opinion of you. It did kill my opinion of the newer list member. -------- John Jung Firestar II N6163J Surprise, AZ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=3594#3594 ________________________________ Message 5 _____________________________________ Time: 06:39:31 AM PST US Subject: Kolb-List: Re: Kolb List Participation From: "John Jung" --> Kolb-List message posted by: "John Jung" Group, This list is like family to me, too, and I just want us all to get along. -------- John Jung Firestar II N6163J Surprise, AZ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=3620#3620 ________________________________ Message 6 _____________________________________ Time: 06:40:33 AM PST US Subject: Kolb-List: nuts n bolts From: "Paul Petty" --> Kolb-List message posted by: "Paul Petty" Fellow Kolbers, I am installing the AN hardware in Ms. Dixie for pre final assembly to make sure everything fits and works before taking apart for final paint and covering.

The exception to nylocs is in extreme temperature environments, like things attached to an engine where the heat would weaken the nylon. There are all-metal friction locking nuts for that application. Take a look at your inlaw's RV-8. Even the aileron bellcranks use nylocs, because there's a brass bushing that the rod end moves on & the bushing is locked down by the bolt/nut in the weldment. However, the rudder pedals probably pivot on the bolts themselves (if they are built like my RV-4) & a cotter key is required. Logic is that a rotating bolt might overcome the locking force of the nyloc & unscrew the bolt. Cutting threads will weaken the bolt (original threads are 'rolled', not cut), but the clamping force required for a control stick isn't likely to stress the bolt at all. The much simpler solution, if you have room, is to just add a couple of flat washers under the nut. AN specs allow up to (I think) 3 or 4 washers under the nut, & you can add a couple under the head, also. The logic is to allow for just the problem you are encountering, without having to recut threads.

You're probably referring to a PM that I recieved and accidentally ended up sending to the list. I of course apologized to the original sender and did what I could to debug how that happened. Unfortunately, his subsequent reply appeared to gloss over the apology and accuse me of doing it deliberately, tempting me to withdraw my apology to him (though I won't do so at this time since I may be inferring something that wasn't actually there). Apart from that, I do apologize to John and the list for that unfortunate accident and I'll make sure it doesn't happen again.

Hi Paul, Boy are you going to get action out of this one. I was trained by an old Airforce Col. If it has a part that moves or rotates on the bolt, use a castle nut and cotter key. If it snugs down and holds compression, use a nyloc. If it gets hot, use a metal lock. BTW, Although pricey, there is a nyloc castle nut available. I like them for the control stick position because if your cotter key goes you still have a nyloc. My feeling is that if it gets loose it will take a while to back off.

There is nothing different about the plane from the origional plans that I can find except the longer legs, which would not or should not effect it's flight charistics to any degree. I have not weighed it or checked its balance for location of center of gravity, but again my instructor didn't feel that it was very far off if at all.

I have enclosed a copy of the doc file for your and others viewing pleasure / evaluation. Also with the mapsource program I can see graphically, though I cant seem to capture and download to a file for others to read or see the altitude for every crumb. I also through the program can see every move he made with the plane, two circles and several straight paths. He indicated that he did two stalls.

Here is how I check my airspeed: First, I pick a day without much wind. Then, I try to determine which way the wind is going by watching for drift and comparing the GPS with the airspeed. When I think I am going straight into the wind, I fly a a chosen airspeed and make note of the GPS. Then I turn around 180 degrees, hold the same speed, and get the GPS reading. If I average the GPS readings, I should have a true airspeed. This process can be repeated to give a more accurate average. It also can be done for different airspeeds. As long as the wind is steady and reading are taken while flying nearly into the wind and 180 degrees downwind, the results sould be decent. Flying in any other direction and trying to average will introduce an error. To check for accuracy at stall speed, I do the above check at 5 over and assume that the difference is the same. My Firestar stalls at 38 or 39 when not in ground effect, 40 indicated, and 3 to 4 mph slower in ground effect. I never count on ground effect. I never really noticed it when I landed it on short grass strips, but I do when I ease it onto a paved runway. -------- John Jung Firestar II N6163J Surprise, AZ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=3713#3713 ________________________________ Message 26 ____________________________________ Time: 12:41:15 PM PST US From: "mike moulai" Subject: Re: Kolb-List: Re: Verner Engines --> Kolb-List message posted by: "mike moulai" All, Jabs are now 85hp and tappetts are hydralulic so never have to be adjusted.

If we all operated on the basis of all those million to one chances we would all stay in bed. That kind of thinking is being pushed by the hundreds of Health and Safety Inspectors that swarm over the country wasting every ones time trying to guard against zillion to one risks. My village recreation field has goal posts permanently set up for the use of the local team. Since time began there have been hooks screwed to the back of the posts to which the groundsman can easily attach the net. The Health and Safety guys have just ordered that the hooks must be replaced with closed loops `beacause the goal keeper might catch his finger in a hook`. There has never been a case of a goal keeper getting his finger caught in the history of football, but `it COULD happen` Likewise. We had an ex test pilot who kept his Tiger Moth on my field. He would have his plane out, checking it when I arrived at the field. I would get out the Challenger, check it, fly for an hour, refuel and put it away. He would still be checking. I am not quite sure what conclusion to draw. Was he safer than me? I dunno. The odds on either of us getting a rock stuck in the elevator are still about googleplex to one.

Our Kolbs wings are flat, if built per plans, so washout should not apply. What can happen is that one wing may be at a different incidence than the other. This could have been caused by the builder or by what I will call "an aggressive landing". In either case, it can be checked by comparing the wing incidence at four points, without moving the plane. You want to measure the wing tips and the wing roots. Level the wings, side to side, and raise the tail up about 3 feet. Use a four foot level, and holding it level and up under the trailing edge, measure and record the distance from the front to the underside of the wing. If the two readings on the same wing are not the same, you may some twist. If one wing is different than the other, you have an incidence problem that can be adjusted, by methods that others have discussed. If you don't find any significant differences, then you just need a trim tab. No matter how careful we build them, it doesn't take much to cause the need for a trim tab. I flew mine for years before adding trim tabs, then wondered why I waited so long. It is nice to have it fly straight without having to hold a constant correction. -------- John Jung Firestar II N6163J Surprise, AZ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=3733#3733 ________________________________ Message 30 ____________________________________ Time: 01:41:52 PM PST US From: Charlie England Subject: Re: Kolb-List: Re: 40 MPH Stall --> Kolb-List message posted by: Charlie England Possum wrote: >--> Kolb-List message posted by: "Possum" > >Can you provide a link to the $35 hall asi product? > >Thanks, > >Charlie > >-------------------------------- > >http://www.hallwindmeter.com/wind.php > Ok, can you tell I don't fly UL's a lot? :-) I read the note & got it in my head that you were talking about an electronic no moving parts pressure sensor type asi.

And the tangs the bolt goes in are also weaker than the shear strength of the bolts. As you might imagine, the fatigue strength is even less than the bending strength or the strength of the tang lugs ("lug" is what a fitting with a hole in it for a pin or bolt is called). Spacers don't affect the bending strength unless they are tight on the pin. And they don't affect the lug strength unless they are integral to the lug. However, by reducing relative motion, they reduce chafe and abrasion on the pin/bolt, and that helps maintain the ample strength of the joint. Still, experience has shown that the joint is amply robust and quite safe. Dave Paule Boulder, Co ================ << I worry about a shear load spread out over that much length of the pin... Or is this simply a low load area such that this is plenty of strength? >> Lucien, and Fellow Kolbers - The wing spar clevis pin in our Kolbs is a 5/16 inch diameter pin. It is made of high-strength alloy steel, rated at 125,000 pounds per square inch. If you do the math, you'll find that this little pin can withstand about 10,000 pounds in shear.....

That is the worst fate I can immagine, not living life because of paranoia and fear. In the end those "safety freaks" are not any safer than the rest of us, because many times the thing that gets you is something you never thought about. In flying being paranoid about is not good.

All the control checks in the world will not help you if a rock gets thrown into the elevator on takeoff. If you get a guy that is so paranoid about the controls that he is constantly checking it, repeated times before takeoff, he will probably forget something just as important such as setting the flaps, the trim, or a million other things that need his attention.

And how did you determine the number and distance? Would you be interested in making additional ones? And NO I am not a lawyer, nor would I sue anyone if the didn't work!

These were on the full ribs. I then attatched the second set on the false ribs and I set those with the back of the VG's even with the front of the previous set. I have included the information that I received to make mine. I attatched them with double sided servo tape from a hobby store. It does well. If for some reason they don't come through let me know and I will send them to your email. If you use lexan (1/16 ) You can bend the lexan just as easy as alum, but being clear it is not necessary to paint them. The color shows right through making them almost invisible.

I just sent a post about the placement on my firestar wing and (note that the word is singular, your experience may be different)I found this particular placement to give me the best benefit. That was 11 inches back on the full ribs, and the ones on the false ribs were set so that the back of the new ones were even with the front of the old ones. I did not in the interest of science do any further experimenting. My result was a stall of 26 MPH. Down from 36 MPH. I cannot tell you for sure what my original stall was since I put a static port in the bottom of my pod just under the rudder pedals. When I got the plane it was stalling at 46 MPH, but as I say I do not know how accurate that was.

People with the Firestars seem to like them, so im wondering if they are worth putting on the MK-III ? If anyone has done this I would like to konw how much they help the stall speed and slow speed flying qualities. People with firestars only report losing a couple MPH in cruise, but being that the MK III does 80 in cruise with a 912S I would think that the speed penalty might be greater on a faster airplane. > >Michael A.

They're not that rigid in their ops. If one has the time, no reason not to recheck things. How many retractable-gear drivers were 'sure' their gear was down when they in fact forgot? I agree strange things can happen, and I see no problem in a quick recheck. I know guys who are truly paranoid, and they're no fun to work with. I don't see how such a recheck is 'paranoia'. Ed in JXN MkII/503 Do not archive. ----- Original Message ----- From: "JetPilot" Sent: Friday, January 13, 2006 10:46 PM Subject: Kolb-List: Re: q > --> Kolb-List message posted by: "JetPilot" > > > edchmiel(at)mindspring.co wrote: >> >> >> That very accident is why I and many other pilots I know do repeated >> control checks, right to the stops (no 'wigglin').
