Would you consider rebuilding a 582, when its time. I live 15 minutes from Green sky Adventures the oldest Rotax dealer in the USA and maybe having him rebuild but that might be about $1000 or more. How much trouble was it actually to rebuild I'm thinking about going to the Votec for small engine repair to get ready for when my engine goes TU. What do you think.

>The other wing is repairable....its a strange feeling tearing off the skin of that wing... all the work, paint, time and expense that went in to putting it on!! > Mornin Gang: Happy Monday. I can totally empathize with the above statement and situation. I felt the same way when I pulled the hide off the wings of my Ultrastar to rebuild after a wire strike. I guess tearing up airplanes is something I have to accept if I am going to participate in this sport, whether I tear them up, or Mother Nature. I watched two Twin Stars at Florida Flying Gators Airstrip get trashed in Nov 1987. One man made a mistake that took out a brand new airplane, that later became the Sun and Fun Lt Plane Grand Champion 1988. He didn't do it on purpose, just got a little over zealous and made a poor decision. Richard Swiderski was there. In fact that is when I met Richard with his Ultrastar. No one was hurt physically, but there was a lot of mental and financial anguish. I felt for both individuals and thanked God it was not me who made the mistake or who was in the line of fire and had a new airplane broken. I have totaled every airplane I built (three) and rebuilt all three of them at least once. The MK III has had three tail booms. Now that is a job in it's self, just replacing a tailboom. A heap of stainless steal rivets to drill out. If you have to drill out a pop rivet, carbon or stainless steel, take a mandrel that has already been pulled and use it to push the mandrel out of the rivet you intend to drill. Stick it in the hole and give it a tap with a small hammer. Then drill, much easier than trying to drill thru a hardened mandrel end. If the rivet wants to spin, make a little tool with a flat sharp edge, ground out a little to stick under the edge of the rivet head. This will put the brakes on the spinning rivet and allow you to drill carefully. I need to replace elevator and rudder hinges, but procrastinate for the very fact that I hate to get started drilling a zillion rivets. Oh well, one of these days.

Frank, These motors are simple. Yours is a little more complex than mine, but anyone with any mechanical skill/understanding can work on them. It took me less than two hours to disasemble and reasemble when I honed the front cylinder. The first teardown took about an actual 10 hours total. Now, on the other hand, I like to work on things. If you are the type that doesn't enjoy this type of one-on-one with your aircraft, I would recommend subing the work. I now have a pretty good understanding of my realiable though. Green Sky comes highly recommended. John H. told me about them, and I have had good technical assistance from their mechanics. I look at it this way: Give a man a fish and he eats for a day, teach a man to fish and he eats for a lifetime. Same goes for engines. I could pay someone to rebuild, but would gain nothing. Learning to rebuild myself gives me the understanding, experience, and ship back and forth, or wait in line to have my stuff worked on. One day I hope to have the same understanding of airframes....

If you worked on it yourself, you *know* the degree of quality and care that went into it. BTW, Rut, I'm impressed with your speediness on getting back into the air.

I ground down the baffle a little bit to allow more cooling air back to the PTO. It made practically no difference, maybe 10 degrees (measured at the typical plug base anyway).

I have the B B Q and Quincy on my calendar. Haven't flown into that airport for a while. I like flying down that way, it is where I grew up (TLH) and the turn around point for my first long xc in my Ultrastar in 1984. Time is flying!!! Boy we've gone a long way since those days. Never would have in my wildest 1984 dreams invisioned the flights that my little Kolb airplanes have taken me. They all started with dreams and ended with reality. I'll try to make it to Quincy, weather permitting. john h ________________________________________________________________________________

How bad is the leak? Can you see fuel pouring out of the air filter? Or are you getting fuel residue on engine from fuel vapor standoff from the carb?

My carbs go one way, his the other. Thought about placing aircleaners in fuselage connected with airtex hose or something similar. Haven't gotten around to that experiment yet. Sorry I can't help any more than the above. It is a good eng. Mine is working on a 1,000 hours (983 hrs as of yesterday).

John; Does this mean that "excess fuel from the vapor standoff" is coming forward through the carbs/filters and sucked back all over the engine?

The ram-air entering the carb is not strong enough to keep the fuel vapors from exiting forward trough the airfilters? How to cure it? Turn the engine around and make a tractor out of it.

Subject: Had to Pass This On...
Hi Listers, Al Mojzisik from the RV-List posted the message below to the RV-List today. Besides making a great point, I thought it was a riot. Hope you do to. Matt Dralle List Admin. From: Al Mojzisik <prober(at)iwaynet.net> Subject: RV-List: FAA BANS RV-LIST FAA administrator, Jane Garvey, announced today in Washington that the RV-List operated by Matt Dralle (On the left coast!) was to be shut down. Citing the 51% rule as the reason for the shut down Garvey explained that with the advent of Vans Quick Build Kits the RV-List offered so much additional assistance to the builders that they no longer met the 51% criteria! "These builders are really pushing the envelope!" Garvey was quoted as saying. "They get all there builder questions answered by one simple E-Mail to this list! They no longer have to spend hours trying to figure out the plans and the manuals supplied by the kit builder. This significantly reduces build time and they make far fewer mistakes. It has taken most of the fun out of being the Administrator and besides, that Dralle guy has nicer hair than me!" She also noted. Rumor has it that Vans also supports the ban because they have noticed that the their sales of replacement parts has significantly decreased since people get advice on how to do it the right way the first time from "one quick question" to the List. We were not able to confirm this rumor however. It was suggested by Moe Colontino that builders supply their serial numbers to the list administrator and if they cross check to a Quick Build serial number then they would not be allowed on the list. Moe also asked that if anyone had a spare empennage and NON-Quickbuild serial number he would be interested in purchasing it. Doug Rozendaal asked the administrator if it wasn't possible that she was just jealous because Matt Dralle calls himself an administrator too? (The List Administrator) To which Garvey replied, "Absolutely not! I can care less what he calls himself! Don't you fly that pink airplane I saw at Oshkosh? We'll have to have a closer look at that machine!" After which Rozendaal withdrew his question. Chet Razer and some others at this point in the meeting asked Ms. Garvey if there was any more beer since they were done flying for the day anyway. To which Ms. Garvey responded that that "was an inappropriate question at such a meeting! " After which Ms. Garvey was bombarded with questions about bolt torque, Extra storage space in RV's, numerous engine questions, and finally some misguided newbie asked her about PRIMER! After tearing her hair out (no wonder Matt's looks better) Ms. Garvey suggested that maybe she better have another look at the RV-List ban and reassess her position. She said she is open to more public input if you don't mention PRIMER! You can contact the Administrator at: http://www.matronics.com/contribution.html Please have your Credit Card ready!

Hey John, Guess what? The day you pointed out that the hinges on the Ferguson was worn and to me at the time they did look worn, I preceded to disassemble the whole tail section. What I found would have amazed you and the rest of the Kolb gang. I have witnesses that will attest to it. Would you like to know? Well, I won't knock Kolbs because they're really good airplanes and I like flying them and I would recomend them to anyone who want a strong well behaved airplane not to mention I flew a MK3 for some 285 hours. My Mama always told me if I couldn't say anything good about someone ( I believe that goes for most planes) to not say anything at all. NO WEAR AT ALL ON ANY OF THE HINGES ANYWHERE ON THE FERGUSON. I might add that I run the brace wires fairly tight. Even the bolts at the bell crank pivots were like new. Come by anytime and I'll be glad to show you. The spacing you saw in between the hinges was in both directions which was there at initial installation. The hinges are of a double "X" configuration and seem to be very strong in all directions. I did try to find some wear but did not succeed. I also keep them lubricated with a light oil which probably had a lot to do with the lack of wear. You're right in that they did look worn but if they are I can't find it. There is no side play and no up and down play.The Ferguson is by no means a perfect airplane but it satisfies me and I'm the only one that counts. If I ever get 1200 hours on the Ferguson it will be a long time from now. It will probably be retired a lot sooner than that which means the hinges want have a chance to wear out. Lets get back to Kolbs. My friend Jim is looking into buying a Kolb from another friend of mine (Flint Burns AKA Canary). I talked him out of buying a Rans not that the Rans isn't a good plane but it want fold like a Kolb. Then there's the time involved in building while the rest of us is flying. It is the Firestar, the one I flew to Sun-n-Money three years ago when we all had such a good time around your camper.It can stay close to home where the previous owner can stroke it once and a while. We're working on a new private runway community north of P.C. where we will all have a place to take the planes in case of another storm like Opal. 100' of my hanger was blown away in that one. The new runway is in and I have the exclusive right to have a training operation on the field so long as it originates from my lot. I hope to retire there and fly 'til I can't see. This is one sport that crosses a lot of years and friends tend to last a long long time. I hope you will give me a call when you are down again and I hope to take Bob up tomorrow if the wind isn't to strong.

Hey Richard, It's a 68'' quick ground adjust on a 3 to 1 E box behind a 582. I did have some problems with the set up early on with the prop trying to come apart at the hub. I always caught it in plenty of time though because I use the inspection tape across the gaps between the blades that IVO recommends. It took IVO three new sets of blades before we worked the problems out . He would have given me my money back but I wanted to solve the problem. There were others who had the same set up and the same problems I was having. I've had three of the cams at different times on the end of the torque rods break. THAT WILL WAKE YOU UP especially if your a long way from home. That made it virbrates really bad at high RPMs but at cruise it wasn't that noticable. Anyway I welded a little tit on the cam end and ground it to the right pitch to match the other blades. No vibration. I have broken two of the backing plates, the thin ones that the adjustment screw is threaded through. I asked IVO to send me one of the thick plates like goes on the other side of the prop next to the gearbox. He did with a thin one to hold the adjustment screw. I put the whole thing on with two sets of inspection tape forward and aft across the gaps. I've never had another problem except when I kill really big bugs. Never broke another piece of tape except when I pulled the prop to do a 50 hour inspection. I also torque the prop bolts to 215 inch lbs. and check them@ the recomended intervals. So far the torque stays where it's suppose to and I am happy with the IVO'S smoothness and quietness. I hope this helps.

Have you ever rebuilt an engine before? Do you have the proper tools? Are you willing to spend the money to buy the special tools and the shop manual? Are you mechanically "handy"? If you have never rebuilt an engine before, go to a motorcycle junk yard, and buy an old rotary valve Kawasaki two stroke engine. Tell the guy you just want it to practice on, it will not need to run after you finish. Get the shop manual for it. You should be able to get both for under $50. Completely dissasemble the engine AND transmission, and reassemble it. If you felt comfortable doing that, and everything made sense, and seems to have fit back together right, now YOU decide if you want to tackle your 582. Either way, it was good experience, and money well spent. If you decide to rebuild the 582, get a GOOD set of snap ring pliers, the magneto puller, the wrist pin bearing tool, and especially the little tool that goes over the end of the rotary valve shaft. Get a good torque wrench. Understand what the book is telling you to do before you do it. If in doubt, ask someone you respect. Get a helper that is patient when it comes time to slip the cylinders back over the pistons. If you can get a helper that has rebuilt 2-strokes before (successfully!), you are ahead of the game.

And >this is considered "normal" for pusher applications because of how the >carbs are located? The ram-air entering the carb is not strong enough to >keep the fuel vapors from exiting forward trough the airfilters? I think what it means is the air stream is blowing fluel out of the air filters. I have used small conical K&Ns thru out life of eng, minus a couple experiments with 6 inch flat/round K&Ns. Flat filters really messed with carb performance (primarily hesitation during hard acceleration). Ram air screws up fuel mixture calibration with these Bing Carbs. The float bowl chamber has two sources of static pressure: vent tube and one on the inlet lip of the carb. The vacumn chamber reads these two static air sources and throttle setting (intake vacumn) and positions the piston w/fuel needle attached, in the correct position to deliver the correct amount of fuel being demanded by the eng. Stray air pressure or vacumn to the two static ports screws up the carbs mind and eng performance, at times. Right now I live with the following: I connect the two float bowls with one piece of tubing. Mid point of tubing I drilled thru both sides of the tubing vertical as well as horizontal (gives me four 1/8 inch holes). Now both carbs are reading the same static pressure at their float bowl vents. This prevents one carb running at different mixture than the other. This mod seems to work well, but not perfect. Next I have to work on getting good static source to the inlet static ports. Two ways I think I can do that: One way is put the aircleaners in the fuselage out of the airstream, using tubing and one or two air cleaners. Or maybe using tubing and a 90 degree bend to turn the aircleaner perpendicular to the airstream. The other way (and not my idea) I saw in a picture of a trike powered by 912. They had fabricated hoods, same shape as conical K&Ns and a little larger to place over the filters with maybe a 1/2 inch gap all around. These could be metal or fiberglass. I think either way would work. The latter, with hoods, probably be the simplest. >Is it possible to turn the intake manifolds around on the engine so that >the carb sits on the backside of the manifold and "going backward" same as >the motorcycle?

That was one of my original thoughts. Carb problems on pusher 912 are not overwhelming, just annoying, especially when one invests that much money into an engine. Last year I bought a brandnew 351W Ford eng for $2,000. I could buy five 351Ws for same price as one 912. hehehe Keep 'em flying, john h ________________________________________________________________________________

Stephen, on pain of my being wrong as usual, here's what Dennis told me when I went to Phoenixville to see and buy a FireFly. I asked why the FF had TWO lift struts, when the other, heavier Kolbs had only one. Answer: to give FF more drag to keep it under 63 mph. I have never heard of a Kolb wing twisting in the wind. I realize others may say I'm wrong, so ask Dennis. GB ________________________________________________________________________________

Good Morning Steph..... and Gang: Single strut bracing on the wing allows for wing twist and failure..................... If the above were true, there would be a lot of Kolbs out there with failed wings. To start with, we'll get this out of the way quick, Firefly has two lift struts per wing section. I assume you are talking about lift struts although you say "single strut bracing." Wing twist was a way of life with the Ultrastar, but I know of no Ultrastar that had a wing failure because of wing twist. Of course I don't know much, but I have never heard of such. Firestar didn't have wing twist because Homer Kolb and Dennis Souder and the rest of the gang at Kolb Aircraft came up with a much improved mainspar attach system to the inboard rib. Likewise, the remainder of the Kolb line. I invite you to try and twist the wing of my old MK III. Don't worry. The folks on this list that fly Kolbs are not alarmed by what you say. We have a lot of combined experience in the air in all kinds of weather, wind, loads, etc. How this helps you out with your research.

Hmmm, I'm sure you'll get a few answers on this one. :) The question about single lift strut is probably the biggest single false rumor I hear about the Kolb from the unknowing. *It is obviously a fair and reasonable question*, but any rumors about this being a weak point in the design are simply from the unknowing or the envious. If you build a Kolb, you easily see the aspects of the internal wing structure that bear wing twist loads. It is clever, light, and very very strong. I only know of one properly built Kolb wing that has ever failed, this one from John Hauck, who was treating the plane more like a Pitts Special. I'm sure he'll chip in here; it was a high time original (5 rib) Firestar always flown extraordinarily hard (any and all aerobatics), and failed just after a hammerhead or something similar. Kolb is the *only* manufacturer who has flight tested one of their planes to the point of structural failure. It failed far beyond stated load limits, was not a wing twist failure, and was even improved upon from that test. Here's an example of the typical rumor on this. A guy I used to fly with scoffed at my single lift strut Kolb. In typical "Unknowing" fashion, this person drilled (4) 3/16" rivet holes 1/3 the way up on points for a 2 gal gas can on each strut!!! What a fool. He assumes the Kolb lift strut is inadequate, but he drills holes and adds a large mass (the filled gas cans) to the middle of a key structural part of his Challenger. I still can't believe it!

Hi Guys: A previous note on this list indicated that I had a wing failure on my old original 5 rib Firestar. That is absolutely true, but the cause was not from wing twist. It was from 755.0 hours of extremely hard flying, 1000's of aerobatics combined with many long XCs flying overloaded in all kinds of winds and weather. I flew this old Firestar like there was no red lines anywhere. We were always wayyyyyyyy out of the flight envelope and eventually just wore the little airplane out. This was the 1988 Sun and Fun Grand Champion Ultralight and the 1989 Oshkosh Grand Champion Ultralight. This airplane flew in 32 different states and Canada, just me and airplane. I learned from this experience, that nearly cost me my life, that stress is a cumulative thing. My little airplane started out life with a whole number: 1.0. Everytime I stressed her I was subtracting a little from that whole number. Eventually I asked her to do something and she told me very abruptly, "Sorry, can't do it!!!"

I have a pretty good handle on the database of Kolb accidents. Structural failure is not on the scope. Crow hopping accidents, engine seizures, first flight/ inexperience related accidents, there are alot of these. There is one "structural failure" but this one is cannot be fairly chaulked up to the Kolb company because the builder failed to install a major structural bolt.

I should change this thread subject line to "Loose Lips ...MINE". On my post about this earlier today, I made reference to John's FS wing failure. He had related that to me as part of a private (him and me) email exchange several months ago, and it was our understanding that it was private info, certainly not mine to make public. So today I screwed up badly. While writing earlier today, I had myself thinking I was repeating a piece of that exchange that was perhaps known history. But I started to realize my mistake more and more as the seconds passed after hitting the Send key. I blew it and my sincerest apologies go to John. There is no way I can undo that send. I just wanted you all on the list to know that I've sucked John into a discussion that might better be left dropped. Worst of all, I slipped and breached a mutual understanding.

I find that most of the repairs that are required in normal everyday little crashes, scrapes, rips, and tears, a few bent aluminum tubes, and cracked nose pods, etc., can be fixed with what ya got left over from building, unless it has been a long time since you did your building, but by then you know how to do most of it cheap. Big jobs like rebuilding fuselage, building new wings, or your butt, can get right in yo pocket book. Neat thing about these little planes is that most of the repair work we can do ourselves cause we built these little suckers. For us that have our planes registered EXP, we get the FAA Repairmans Certificate for our particular airplane and can sign off on all our repairs. Don't have to hunt down and a&p to do it for us.

>I am considering building a Kolb Firefly or Mk III. I was recently told that the single strut bracing on the wing allows for wing twist and failure. Steph and all, I would say the person who told you that was incorrect. I think the Kolb wing is very strong. I just helped a friend cover his today. It uses a 6" main tubular alum spar, built up ribs and drag strut, steel inner rib and attach points and Stits cover that prevents any twist. A single lift strut is very adequate. The streamlined formed lift strut when lined on the inside with a second tube can function without even the jury strut. The only reason that Kolb uses double struts on the Firefly (I was told by a person within the company) is to add more drag to fit within the Part 103 speed requirements. I have the MKIII (jury strut free) and am very happy.

Subject: Re: Wing twist - UltraStars
I too had an "early edition" UltraStar that lacked the inboard ring around the end of the tube/spar. I added a ring using chromoly flat bar & plate. Form the flat bar into a ring of 2 halves with the 4ends bent out 90* & drilled (so the 2 halves can be bolted down on the tube.) On each half, I welded 2 tabs, spread equally apart on the edge of the ring. The face of these tabs are perpendicular to the spar & parallel to the edge of ring. This is then bolted & rivoted onto end of spar. then out of the flat plate I cut out an X that connected the 4 tabs & rivoted it to the 4 tabs. All the rivot & bolt holes should be drilled before welding the tabs as the metal will be difficult to drill afterwards. All this can be done with just a 16" hole cut out of the inboard side of the wing. The difference in handling was astounding. It was crisper & rolled much faster.

Stephen, I have the 5-rib wing of the Original FireStar and my buddy that I fly with every weekend has the same. He bought a used one and after taking the fabric off, noticed extra drilled holes on the bottom of the main spar, at the H-section, because the builder botched the repair job after an accident. He has checked it over thoroughly, the A/P mechanic that he is, and determined the plane is safe to fly. That FireStar I'm sure has over 400 hrs logged in 12 years with the 447 40 hp engine. He does inspect the spar on a regular basis and sees no problem. My FireStar has 420 hours on it and we both are flying out to AirVenture '99 next summer. If there was a problem with our older FireStars making a trip like that, we definitely would not be doing it. You can expect to see two Original FireStars out there, one with extra holes drilled in a place you wouldn't want them, but then that hefty 5" spar has proven itself on other Kolbs in many compromising situations. Back in my early days when I was learning to fly the thing and I'd have it in a 90 mph dive by not paying close attention to my airspeed and if there was a wing twist problem, I wouldn't be here telling you this. By the way, we both fly without parachutes. I say this not because we are stupid pilots, but because we believe in what we fly is more than adequate to get us there and back again ....... safely. Any more questions? Ralph Burlingame Original FireStar, 447 powered writes: ..... a concern I have >is in the single strut brace on the wings.

Hi Stephen: Can't resist getting my .02 worth in too. I mentioned some time ago to the group that I had to make a choice while building my Mk III. I had enuf money for full radios ( for flying in LA airspace), or a ballistic chute - not both. Chewed my nails some till I built the first wing. Hah ! ! ! Sent the money for the radios. Maybe get the chute later, but I doubt it. If you'd like some numbers, consider this: The main spar is 6" dia. and measures a little over .090 wall. There is a massive steel rib / ring solidly rivetted to the inboard end. 9 more ribs are rivetted on with 10 steel rivets each. An additional 18 half ribs are spaced between the 9 full ribs, and rivetted to the spar and to the leading edge. Full ribs are rivetted to leading and trailing edge spars. That's for each wing. Drag struts are 4 - (four) - thicknesses of thick aluminum tubing, telescoped and steel braced. One of my pilot / builder buddies said "My gosh, you could hang a 172 from those, and they wouldn't even creak." Nuff sed. Just something to get the group going - maybe a little twist - built in - wouldn't be that evil a thing. A little washout might make it almost unstallable, cause the tips would keep flying after the inboard sections were stalled. Course, I understand Kolb's are very mild in the stall anyway. And, thinking about it, you'd probably lose some lift. Any of you engineer types have any thoughts ??

During my ongoing search for ways to reduce my EGT's I found that the factory- set timing was 2.2 degrees late. Rut Fuller confirmed this observation and worked with me to insure dead-on resetting. Tom Hertz, our resident factory- trained expert, was not so sure we should have reset the factory's timing because he thought they set it electronically at during the factory test run and it was optimized for this particular engine. He reasoned that the standard .086-before-TDC / eyeball-to-reposition-the -transducer method was a field fix and probably not as accurate. My argument is that even if they use a timing light, access for repositioning (tweaking) the pick-up transducer would be a major problem. Yes, the EGTs did apprear to go down slightly after we reset by the "field" method. Here's another thought on EGT probe/gage systems. Are Tempilstick temperature indicators accurate enough to use in varifying calibration ? For folks who don't know Templesticks look and work like color crayons but the marks they make melt at a given temp. It would seem that we could put a Templstick mark on the probe and watch the gage as we apply heat with a heat gun. I bought two of them at a local welding supply ( $8 a pop) but they did not know much about them. I remember that we used them in liquid rocket engine test firings but that was long ago.

The pterodactyl had that washout, and I considered it one of the safest to fly because of it................very docile in spite of having a short chord.......GeoR38 ________________________________________________________________________________

Hi Gang: Been a while since I did any covering, but I doubt if it has changed since I last covered my MK III wings in '92or '93. I was self taught how to cover, dope, and paint fabric covered airplanes. Started in '84 and did a lot of it until the final cover on the MK III. Out of three airplanes I built and finished, two of those planes got the wings covered twice, the MK III had two sets of wings the first few hours of flight. All turned out pretty good. What I learned about covering and painting I got out of the bible "The Stits Manual" and the covering and painting instructions that came with each particular plane kit. I found if I did what Ray Stitts told me to do I would get good results. I did and it worked. I shrink the fabric tight, cause in the winter the fabric will loosen up some when it gets cold, and I do not want loose fabric. I shrink the fabric on the wing before popping fabric rivets. Once the fabric is tight, if a rib has a little curve to it, I can straighten it up thru the fabric. Once it is riveted, I lose that option. Outboard false rib won't go anywhere if it is properly braced before covering and shrinking. It is awfully rewarding to do a good covering job and a lot of fun. Enjoy it while you are learning and when you are doing it, cause when you finish, that part is all over. Don't personally recommend rivets before or during the fabric shrinking process. Gotta go look at the Atlanta and New Orleans sectionals, maybe Jacksonville too, and get ready to go to the BBQ Flyin at Quincy, Fl, Saturday. Gosh, I haven't been anywhere since OSH.

Unfortunately, after his death, his daughter threw away a lot of his papers, including the pictures of the original, and it's paint scheme.

>Is there any use to having an ignition breaker in the BRS trigger, so the >ignition would be cut if the chute was deployed? Has there ever been an >instance where the chute became fouled in the prop? Or worse? Hi Duncan and Kolb Gang: I have used a hand deployed prcht twice, both times forgot to kill eng. First time was still at full throttle when chute deployed, second time was at idle when deployed. Both times the eng was still idling when we hit the ground (me and the plane). I think I recall a prop fouling a chute. It'll wrap right up in a second. My Brother Jim made me a kill system for my 582 from a Radio Shack Plastic Box and two sets of Ford ign pts. Took some 1/16 lexan hooked to a 1/16 inch cable which was hooked to the bridal loop at the apex of the canopy. The lexan went into the pts which were spliced into a wire from ground to kill wires. When prcht fired, cable pulled lexan out of pts and killed eng. Believe me, unless you are some kind of super cool dude, you won't be thinking of hitting kill switches or anything else except getting your buns safely on the ground. When I replaced the 582 with the 912 I didn't reinstall the kill box because it added to the complexity of removing the center section. Do I really need it? I don't know. It is debatable, but for now I fly without it. john h ________________________________________________________________________________

Subject: Floats and gross weight
Hi, I'm interested in putting my FireFly on floats; maybe a Full Lotus monofloat. It seems like a Full Lotus Monofloat 1000 would be sufficient, but the FBO at a local airport has a few used and new 1700 and 2000 Full Lotus monofloats which he just aquired and is interested in selling (he doesn't know what he wants for them yet though); would something like that be overkill for the FireFly? If I do this, it would definitely have to be an amphib setup; I don't want to be stuck with land or water, I want to use both... According to Full Lotus' web page, the 1000 and 2000 can be set up for amphib (pricey!!!!! $$$$$$) :-( but the 1700 can not. (Any less costly options here?) My main question though is... I'm already at gross weight for my FireFly. Actually, I'm slightly over, maybe 520-530lbs and I believe the gross weight for the FF is 500lbs. Does adding floats affect the gross weight? Obviously they'd add weight, but I thought maybe they act as a "lifting body" which would offset it... ? Oops, I thought of another question: How does the monofloat attach to the plane? Is there a mounting kit or something that I need to buy from someone? (Kolb?) If so, anyone know what it costs? Ummm, one more question. :-) If I were to get my FireFly on floats, I've played with the idea of registering it as an experimental so that I could build float time (for reduced insurance premiums, etc). Is there any problem with using Full Lotus floats on an Exp. aircraft? Any "gotchas" to look out for here with registering my FF as an Exp floatplane in general? (I am the 2nd owner, and not the original builder.) Any info or advice on any of the above would be greatly apprecated. Thanks! -Jon- ________________________________________________________________________________

Yes, there have been cases where the pilot didn't not turn off the engine before deploying the chute. My own experience: upon inspection of a 2 seater Q/S before I took my first lesson; my friend (experienced pilot, came along to see if I'd puke after the big breakfest he gave me) found on the BFI's plane that the static strap that holds the chute to the frame would have fouled because of the way it was tie-strapped on the vehicle! IMHO ::: Ignition breaker would be nice, but I can for-see the problem will be the propeller windmilling for a few seconds or so...it would have to have a delay of some sort so that prop stops before deployment of the chute... -Mark- From: Duncan McBride <dmcbride(at)indigo.fgcu.edu> Date: Friday, November 20, 1998 8:02 AM Subject: Kolb-List: BRS > >Is there any use to having an ignition breaker in the BRS trigger, so the >ignition would be cut if the chute was deployed?

Subject: Re: Floats and gross weight
Jon, I've thought a lot about adding floats too. I haven't decided yet, but I do know that I wouldn't add them unless I could do it for under 80-100 lbs. Even that much added weight is a significant compromise to what used to be a 300 lbs empty weight plane. The other big piece of it is that even without floats, you can land in a ton of places right next to the water. I know that ain't the same, but that and the fact that tundra tires and good gear allows much rougher, shorter landing spots in a variety of places is a valid argument against floats. Then there is the compromised flying attributes of the plane and the added risk of water operations. All that said, I'd still love to have some super light floats and may build them someday. As for the gross weight thing, I'd assume that the float is not a lifting surface, rather, just added empty weight. One thing about registering Exp, I assume then that you would need to get a Seaplane rating.

I have an engine shut down switch built into my Chute deployment handle mounting. It is out of reach so it won't be accidentally be actuated but it is physically tied to the actuating handle. If the engine is running WOT and the cable gets hung in the prop at least the prop won't have a full power stroke behind it. The BRS reps at Sun-n-Fun liked it but said it was more important to make sure that the rocket, cable and canopy have a clear exit path. Mine is a built in soft pack which means I have to have a door or burst-open hole for exit. I am satisfied that between my carefully designed exit, automatic shut down switch and IVO prop which I think would quickly shear off if it met the cable I'll have a pretty good chance if I ever had to pull that handle. I'm not sure one of those nine pound Warp props would shear as easily. Duane the plane in Tallahassee ________________________________________________________________________________

I've seen several planes with this setup, as a backup. I plan to implement it in my Challenger currently under construction.

Not hardly. I can almost guarantee you won't want to be sitting there fat, dumb and happy, waiting for your prop to stop so your chute will deploy. Uh, uh!!!!!!!!!!!! If and when you get in a situation when use of the chute is necessary, it won't be like on a nice Sunday afternoon flight where you have time to decide what to do and nonchalantly do it. Your altitude at the time is a big determining factor, attitude of the acft, is it stable, spinning, flipping, flopping, what ever. It will be a big shock that demands instant action, right now. My first deployment was at 200 feet and 75 mph. Airspeed saved my buns. Second deployment was aprx 500 feet. Not a split second to try and decide what you are going to do, when the acft is in a 90 degree dive screaming out of the sky. I few days before I used my prcht the first time I was in Florida at my brother Jim's house. We we were going to repack the chute. Jim asked me if I had ever practiced throwing the deployment bag. NO! He sat me down on an airconditioner unit with my prcht on and said: "Deploy it!" I did. Several days later I did it again from the seat of my Ultrastar at 200 feet AGL. I also practiced in my mind over and over what I would do if I had the requirement. It was second nature, automatic. Same, Same in the Firestar. I practice reaching for the deployment handle on the ballistic chute in my MK III. I know where it is and I can get it with either hand or both without looking for it. In a wildly spinning tumbling acft it may be more difficult locating and pulling that red handle. Make it second nature to be able to do it without thinking about how you are going to do it. And don't fly with the safety pin engaged. I remember a gentleman at Sun and Fun 1990 who saw a video of my prcht deployment in the Firestar. He said he thought he would put his prcht back in his airplane after he viewed the tape. He had flown with it for 6 months and didn't need it, so rather than carry the extra weight around he took it out. To me the prcht is insurance. I don't know if I'll ever need one again, but if I do and I don't have it, it won't do me any good. I've carried the 21 or 22 lbs of prcht with me since day one in the MK III. Never flown the airplane without it. It is a permanent part of the airplane. I don't realize the extra weight; to me it is not extra.

Ray, I cut one of mine down by 1/4 length and then cut a slot (about 1/4 of the circumference) out, then I screwed it to the wall and kept all my tubes in it. The cut length allowed the uncut tubes to hang out so I could see what was in there (it was mounted on top of a shelf above eye level, but out of the way) The small piece I just screwed to the wall and put any small cut pieces in so I could see and use them possibly later.

Guys, A rectangular wing will stall in the center area first and this is why you will hear the "burble" in the prop prior to stall. There is no need to add any WO with this type of wing. I'm sure this is exactly why Homer used this design.

Hello everyone, Richard came and took the SS away yesterday, so it's time to move on. I'd like to thank everyone on the list for all the advice and entertainment I've received over the last couple years. Even though the SS didn't turn out to be exactly what I wanted, I don't consider the time and money to have been wasted. Overall, it was an enjoyable experience, and along the way, I met some great people, and made some lasting friends. Later today, I'll be leaving the list, and also removing the SS pictures from my web site. Will Uribe has volunteered (didn't say no fast enough ) to post some of my pictures as long as there's any interest. I sent him a CD-ROM last week, so he's got them all. Thanks Will. Take care, and I'll see you in the sky when the RV-8 is done.

It was good visiting with you over dinner (thanks again) when you passed through Dallas. I hope the progress on your RV goes quickly and you are into the air quickly. I flew today for the first time in about 3 months. I couldn't believe it had been that long, but my logbook reminded me. I have little excuse except the building of our house in Central Texas. It only took me one landing to feel comfortable again. I raised the clip on the needles of my carbs one notch and they are preforming perfectly as regards the EGTS... right around 1100 instead of below 1000. All the other gauges are in the optimum range. I noticed that flat out straight and level my rpms were climbing above 6500. I may tweak in a little more pitch on the AQ-IVO. I bought a used ICOM headset adaptor for my ICOM A21 and it works very well. I never could get the intercom (cheap one) that I bought to work properly. Now I will be able to announce my intensions instead of just listen to others. I feel a lot safer now. The traffic at our airport today was busy with usually two or more in the pattern. Pretty soon I will switch over to the full doors and full enclosure as the temps are beginning to turn cooler. Today was cloudless with a 10 mph wind aligned with the runway and mild temps. Perfect.

I have made several fiberglass fairings /gap seals on my FS2 covering a second chance softback. I used laminated balsa for an exit area as long as the pack opening and about 3/4 width. Make sure that the areas surrounding this exit hole are smooth and snag free. It would be a real letdown to have a successful deployment of a shredded chute.

David, I'm at a loss to help with your reference but it sounds like you know what you want the 'waiver' to say - so why don't you just write it? Actually the above couple sentences would probably do. I had to sign a "waiver" to rent my hangar. Upon seeing it, I asked the landlord where she got it. She said she had paid a lawyer a couple hundred bucks to write it up. I compared my copy to a standard lease agreement available for about 50 from any office supply store - virtually identical! The lawyer skinned her for a couple c-notes by taking a standard lease and replacing the word, "contents" with "aircraft." I didn't have the heart to tell her I was flying a "vehicle," not an "aircraft!" -Mick Fine Tulsa, Oklahoma http://www.angelfire.com/ok/froghair Green Country Ultralight Flyer's Organization (UFO) http://www.angelfire.com/ok/gcufo ________________________________________________________________________________

Subject: New List Subscription Form!
Dear Listers, After a full weekend's work, I've come up with a really nice new List Subscription web page. The page allows you to Subscribe, Unsubscribe, and Search for your email address on any of the Email Lists. Subscribes will still require Administrator Approval, but the page should really go a long way to making the overall process much smoother for everyone. The standard Majordomo email method is still available, but I strongly recommend to everyone that they use the web page excluseivly. I have also made some rather extensive modifications to the text trailer appended to each of the messages posted to the List. I've added a number of web site URLs that should answer many of the questions I seem to get daily. I know the trailer is a little on the long side, but its great reminder for everyone, and I filter it out before appending messages to the Archive. Please have a look at the new List Subscription Form and maybe see if you can locate your address using the search capability. The URL for the new Subscription Form is: http://www.matronics.com/subscribe There are a few other permutations of the "subscribe" portion or the URL that will work as well, for example "unsubscribe", "subscription", etc. But these all take you to the same page, so just remember the URL shown above.

Woody, Ray, et al. Am still alive and more or less, in operation... Thanks for asking... Sent Ray a separate note a little earlier when I came across another one from him... I am methodically working my way through the half-million or so e-mails which have accumulated while I was out foolin around at the office for the last month or so... 'Ol Saddam has us in high gear at work, and I haven't had much chance to even do the eat - sleep - change drawers routine to acceptable standards, much less fool around with the pile of dacron and aluminum refuse heaped in the garage... (good thing I still wear O.D. drawers...) In late October, I finally got some fabric on the horizontal tail surfaces and the rudder... This modest progress was compromised, however, by the fact that my current Bride insisted upon leaving the garage door cracked about a foot, so that her worthless little fuzz-butt cat could go in and out... When I finally managed to get out there to do some work this weekend, I learned that the result of that particular intellectual shortfall has been the apparent adoption of my garage as some sort of high-performance proving ground for exotic feline waste distribution and advanced hydraulic experimentation... and it was evident that at least a dozen or so of the more advanced participants had some bizarre affinity for anything with Ray Stits' name or logo on it.... Particularly the Polyfiber already installed on the stacked-up tail parts... There also seemed to have been a great deal of interest in settling the matter of ownership of the large roll of dacron fabric still under the worktable...it was "marked" virtually from end to end with such a thoroughness, and to such a depth, that a reasonable person would have difficulty buying the notion that this result could have possibly been the result of random actions by uncomprehending dumb animals... In my mind's eye, I could just see the little buggers lined up waiting their shot, each with a little number clutched in his paw, while the furry little foreman directed each, in turn, to the precise location called for in the master plan.... Long story short... The neighbors were treated to the sight of yours truly, on his flabby belly and bony knees in the driveway scrubbing what they probably thought was the longest piece of cheap white carpet they had ever seen with soap and hot water... Most of the obvious stench has abated... although I have now fully reconciled myself to the fact that no machine bearing the distant but unmistakable essence of feline territorial imperative is ever going to grace the big winner's circle at Oshkosh, I guess I need to reassure the cat lovers on the list that no harm came to the 'ol Lady's little fop of a long-haired cat over this... I do admit, however, that I went ahead and cleaned a couple of toilets with him while I had him all lathered up from doing the dacron on the driveway... But I went ahead and dried him off and put him out in the back yard... Did you know those little suckers get about a yard across after 15 minutes on the permanent press setting? He still won't come when I call, but he does stay in the yard when I go outside with food, now.... I cannot see inside the tail pieces, and I absolutely refuse to peel off the fabric and do them again... I washed them out as best I can. I reckon we will now subject 'ol Ray's epoxy primer to a long-term test by a solvent vastly more formidable than mere MEK....

Date: Nov 23, 1998
Happy Monday Morning, Had a good time this weekend. Flew down to Quincy, Florida, for their get-to-gather. Sat morning I got up at six, the OAT was 35F. Ugh!!! Too cold for an old fart to go flying around the countryside without an ECU (environmental control unit) or in our terms, a heater. By eight it had rapidly risen to 38F as I loaded Miss P'fer and got ready to fly. Took a little coaxing to get the 912 to start and run, the enrichers weren't up to snuff for the cold damp air. I bought a new Wal-Mart 14 amp battery last month and it did its job. No need for a jump start. God blessed me with a good day and we were off the ground at 0830, winging our way southeast. I had to stop after an hour and check out the back of a hanger in Clayton, Al, then another hour and I was landing at Quincy. They had a good turnout for the flyin, Kolbs overwhelming all other brands of ULs and Exps. Mike Highsmith and Richard Lovell from Panama City, Florida, were there when I arrived. Both previous Kolb owners, both have decided to fly "other" brands of acft. The Quincy boys had the grills hot and smoking. I sampled some of the best venison sausage I had ever eaten followed by a delicious cheeseburger. Compliments of the Quincy gang. Got to see Ruts "original" Firestar, that brought back some memories of the 80's, and Dwayne's Fire Fly. Both good looking airplanes. My Brother Jim met me at the airport and later took me to St Marks for a delicious fried shrimp, oyster, and Grouper dinner. Thought I had died and gone to heaven. Overslept Sunday morning and got back out to the airport for a noon takeoff for Hauck's Holler. It was misting rain, and cool. The airport was almost deserted. We poured 5 gal of 93 octane in Miss P'fer for insurance, then gave a gentleman, who was flying a two place Quicksilver a short demo flight in the MK III. Needless to say, after getting out of the Quick, he was impressed with the MK III and is going right out and buy one. hehehe I gave him a good flight and the 912 performed first class. With two up and almost 20 gals of fuel, plus my gear in the gear locker, Miss P'fer was climbing 1300 to 1500 fpm. She made me proud of her. However, I think we were taking advantage of the nice east wind reflecting off some rising terrain. I didn't tell him that. Did some steep approaches, couldn't see his eyes, but I bet they were wide open when I initiated the first one. I tapped the vsi with my finger, he didn't have a headset, to show him it had pegged at 2500 fpm rate of descent and 65 mph. What a performance. Couldn't haul her to a stop as quickly as I would have liked to cause the800X6's had turned into skis on the wet grass. Off Quincy and with a pit stop at Clayton, Al, again, was touching down at Gantt International Airport in less than two hours. Not bad for an UL to fly 176 miles. I still had over 10 gals fuel when I landed. I could have made the flt down and back, with play flying at Quincy, and had a five gal reserve, but why take a chance on wind, weather, or some other act of God or Rotax or "Murphy." Had a great time and look forward to the next. john h (trying to get started in Central Alabama) ________________________________________________________________________________

Subject: Re: FS-II AND BRS installation
<< I have almost finished my soft pack (leading edge) installation. I hate to see my alum-lexan gap seal go in favor of fabric seal. I would like to talk to those that have done something other than fabric. How did you rocket or entire chute pack? >> Bruce, I have a Second Chantz soft pack mounted between the wings. The rocket motor, which is about 1.5" in diameter, points straight up and sticks out about 3" above the center section. The center section gap seal is made up of lexan, with a piece of aluminum at the leading edge spar, as was explained in one of Kolbs newsletters. I cut a round hole in the top lexan for the rocket motor to protrude through. I then cut the top lexan to form a trap door, which is about 6" wide and 12" long, big enough for the chute to be pulled through. The trap door is made by cutting two slits 12 " long, fore and aft, about 6" apart, and one slit going across at the aft end, connecting the two 12" slits. The cross slit must intersect the center of the rocket hole, so that the cable is free to pull out the chute, which would then force open the trap door. The 'hinge' of the trap door is simply the lexan 'bending' and is located at the leading edge of the door. Once the door is cut into the lexan, you have to secure it in the closed position, because the natural tendency is for it to spring open, due to the curvature of the lexan gap seal. I just used some tape to hold it closed. The rocket motor has plenty of force to overcome this light restriction. The lower part of the gap seal is harder to describe. On my Original FireStar, there is a U shaped tubing (a hoop) above my head. First I pop riveted a piece of aluminum sheet on top of that, on which I set the soft pack chute. Then I cut out most of the lower part of the lexan gap seal, so the cut out resembles the hoop in shape, but still leaves an edge resting onto the edge of the hoop plate. It just doesn't cover the central part where the chute is sitting. In other words, the bottom part of the lexan gap seal covers the bottom surface of the wing, but only extends onto the hoop plate, reaching in about 3/4" all the way around, for support. Now it gets even more difficult to explain the rest of the job. I cut another piece of aluminum, about 2" wide, in the shape of the hoop plate, with the outside edges even with the previous mentioned hoop plate. Then I cut another piece of lexan, about 1" wide to the same shape as the 2" aluminum, except it is 1" smaller on the outside dimension. Both sort of resemble a horseshoe shape. These were pop riveted together (sandwiched) onto the aluminum hoop plate. This made a groove about 1" in width all the way around on the outside edge, for the lower part of the gap seal to slide into and keep it from interferring with the chute pack. This permits me to easily install and remove the gap seal, which I have to do since I fold the wings after each flight. The gap seal is held in place with velcro at several locations. Any questions?

I thought for sure it was going to be something Hi Bill and Kolb Gang: Just curious about all that carbon. I never experienced carbon buildup and never decarboned a Rotax 2 cycle eng during my two cycle career (except during rebuild). I reckon I just blew the carbon right out of them as I flew. However, I never babied my two strokes, never cruised less than 5800, and yes I did take them on nice long XCs often. I think long XCs at a respectable power setting of at least an hour or more are necessary to keep these little hornets happy and clean. In addition, every now and then, mine got a shot of Marvel Mystery Oil in the fuel tank. I have noticed with regularity that my 912, as well as the two strokes, that are flown only locally playing around the patch, tend to get lazy and lack that sharp crisp feel that they should have. They get to where they don't want to idle smoothly and just get plain lethargic. I can go on a descent XC and the first landing I can tell the difference. Just like giving them a good enema. Cleans them out. On this flt to Quincy, Florida, I put 16 oz Marvel Mystery Oil in 25 gal (twice the recommended oil) and after a couple hours she was back to her old self. More power and much smoother. Not trying to sell MM Oil, but I have used it since 1964, when I purchased my first new Honda 305 Super Hawk. Used to put a cap full in every tank. Did it do any good? Back then I don't know, but I use it now in a 351W marine engine, Dodge Cummins diesel, Kubota diesel, Onan 4 KW generator, and the 912.

Subject: Re: Floats and gross weight
Hi, I'm interested in putting my FireFly on floats; maybe a Full Lotus monofloat. It seems like a Full Lotus Monofloat 1000 would be sufficient, but the FBO at a local airport has a few used and new 1700 and 2000 Full Lotus monofloats which he just aquired and is interested in selling (he doesn't know what he wants for them yet though); would something like that be overkill for the FireFly? As a rule of thumb use a float system that has a bouyancy of twice the gross weight of your plane including the amphib weight and mounting hardware. If I do this, it would definitely have to be an amphib setup; I don't want to be stuck with land or water, I want to use both... According to Full Lotus' web page, the 1000 and 2000 can be set up for amphib (pricey!!!!! $$$$$$) :-( but the 1700 can not. (Any less costly options here?) My experience with the MKIII on floats is to stick with Lotus Floats since they absorb more impact force than rigid floats and the tubes are easy to replace. I would not pinch on the float cost but would look for someone that can make a home build amphib system. My experience with the Lotus amphib system has been less than satisfying. My main question though is... I'm already at gross weight for my FireFly. Actually, I'm slightly over, maybe 520-530lbs and I believe the gross weight for the FF is 500lbs. Does adding floats affect the gross weight? Obviously they'd add weight, but I thought maybe they act as a "lifting body" which would offset it... ? The amphib system of a Lotus Mono float weighs about 35 lbs. Float weighs around 45lbs and mounting hardware should be 15 lbs. Total added weight 95 lbs. It all adds to the gross weight and drag coefficient of the plane.It requires 25% more Hp than std engines for decent water take-off and climb performance due to the added drag and weight. As far as "lifting their own weight", the stall speed of my MKIII with duals appears not to be affected by them compared to what other MKIII owners have reported but I believe that once in the air, weight is weight! Oops, I thought of another question: How does the monofloat attach to the plane? Is there a mounting kit or something that I need to buy from someone? (Kolb?) If so, anyone know what it costs? Although there are Kolbs with monofloats around I do not know of anybody selling a mounting kit. If you can build a Kolb, attaching a monofloat is not that difficult.The amphib hardware and mounting hardware all should be combined in a single design.Kolbs also require a retractable waterrudder for decent turn control on 10MPH+ wind conditions while taxiing on the water. Ummm, one more question. :-) If I were to get my FireFly on floats, I've played with the idea of registering it as an experimental so that I could build float time (for reduced insurance premiums, etc). Is there any problem with using Full Lotus floats on an Exp. aircraft? Any "gotchas" to look out for here with registering my FF as an Exp floatplane in general? (I am the 2nd owner, and not the original builder.) This has already been answered correctly. BTW, when I registered my MKIII as an amphib,the FAA inspector had checked their records to make sure I had a float licence before coming out to inspect it. Any info or advice on any of the above would be greatly apprecated. I personally think that monofloats with sponsons on Kolbs or any other UL look ugly and it is difficult to get into the cockpit and use the plane around other boats and docks but if all you use it for is to beach it maybe you are ok with it.

Hey John, Glad to hear you made it home okay. Richard and I left about 9:30 while we still had a high ceiling. The prediction was for more rain down in P.C.. We both had things to do today and had to get home. Sorry to have missed you. Rut took us to breakfast early in down town Quincy. We picked up some gas for our trip home. When we got back Rut, his girlfriend (Deana) and I got to go up in the QS that belong's to Charles Davis. He's an ASC- BFI .Boy did that bring back memories when I use to train in my QS. Not a good X-C machine but a great trainer. The food and company was terrific and I must congradulate Rut on his first gathering. He's only been doing the UL thing for a few short months and he has already accomplished more than most UL pilots do in their entire flying life. "Way to go Cowboy, YEE-HA". Richard, Rut, Deana and myself took over the FBO after everyone left that night, made a pot of coffee and watched every movie we could find that had airplanes ,collected by the local EAA chapter. Then we watched " Independence Day " again because it had airplanes in it. The rain had been light all afternoon as you know. When we finally called it a night , Richard decides to take his sleeping bag and sleep in the FOB on the couch. The minute I get comfortable in my tent the rain started and didn't let up for five hours. It was nice and not to cool. The water repellant I got from Wally World did the trick on my tent because I hardly got a drop inside and sleep like a log for most of the night. I can tell Richard's days are numbered when he sets up his tent and then takes the warmth of a cozy coach inside just because of a little rain. To bad I didn't think of it first. But then he's only 71 years young with 2000 hours in UL's. I guess he's entitled. For those who don't know Richard Lovel (AKA Bluebird) my wingman. He started flying UL's sometime after he retired from the Airforce, where I might add, he drove recovery boats to pick up downed drones and lots of other assorted things from the waters south of the Florida panhandle. He flew a QS 'til he wore it out then a Fire Star 377 but couldn't wear it out after some 800 or so hours, no rebuilt engine either. He was looking for something with more room back before the FSII came and settled on the clipped wing Challenger. You wouldn't believe how much stuff he can get in there. He probably would be flying the FSII if he had known it was only one year away. Never the less he has 800 hours already on the Challenger and it's still going strong. This guy just loves to fly. If there is any chance to fly on any given day he will be in the air if it's only to fly the pattern. He says this is his last airplane but our friend John Wayland is about to bring his new Sling Shot on line to taunt him a little. Finally he will beone of the slow one in the group for a change. He'll have a lot to think about on those long X-Cs we are planning. Texas, Arizona, Indiana, Kitty Hawk to name a few. He is a world of information on X-Cs and where to go and what to avoid, but most of the time you have to ask , maybe it's because he feels it's more fun to discover things for the first time on your own rather than knowing the end of the story before you get there. He want let you get into trouble but he will let you experience flying the way he and John W. did a few years ago. Hopefully I can join them again in their quest to cover every square foot of the southeast with a UL. Anyway we got home alright. Ran into a little rain and low vis. just west of Clarksville and had to descend to 1000' but no problems. It was right after I sat down at P.C. that the rain came in earnest. We'll do it again next year. Maybe more can fly in, as it was I am glad we all had a safe flight and a very good time.

Definetly a factor, but 2-strokes can be kept pretty reliable. Main thing required is knowledge of what they want, and then the diligence to treat them right. 2-strokes are sorta dirty, loud, need oil added to gas, and deliver unwanted vibration to plane and pilot. With all that, and an ultralight's ability to land in little space means reliability isn't the top of the disadvantage column as far as I'm concerned.

According to the brochures, I'd be ok with a 582 and a two-blade prop, but how about a 912? The brochure lists a three-blade with the 912, but would a two blade stick up as high as a three blade, even if the two-blade was a few inches greater in diameter and the engine had to sit an inch or two higher? Could any of you with a 912 tell me what prop you're using, how much clearance you have from prop tip to fuselage tube, and the total height?

Duncan and Gang: I use a 70" dia 3-blade prop on my MKIII/912. Don't know what the boom clearance and total height is. Have to go to airstrip and measure. Two blade prop would give you a lot more clearance than 3-blade. My 912 is about an inch lower and 1/2 inch further forward than the factory mounts. Next time I go to Gantt Int AP I will try and remember to take a tape measure and get the info for you. john h ________________________________________________________________________________

Something to put in the book. >> Hi Michael, The prop is a Tennessee, wood, 66 X 30, clean it after each flight, looks like new. Had checked tracking and balance before removing engine and both were good. I usually cruise at 4800 to 5000 RPM with this prop (to keep up with my buddy who has a KXP 447 with 66 X 32 and turns 4500 most of the time). My CHT about 250 and EGT indicates 1100, sometimes lower. Plugs are a nice light chocolate brown color, so mixture appears to be not overly rich. But apparently something is making lots of carbon. I'm using Castrol Super snowmobile oil @ 50:1 I know the reccomended prop for this engine is 66 X 28, but when I originally got my kit it had a 66 X 32 prop and I flew with that one 3 years. And I turned less RPM, in the 4200 to 4500 range The EGT then was really low, in the 900 to 1000 range. It didn't seem to make as much carbon, but it did make it and I decarbon every winter when its to cold to fly. I mostly use Amoco fuel, but have also used others on occasion. Guess I'll have to start experimenting to see if I can reduce the carbon buildup. Funny thing is, it only gets on the piston dome. The heads are clean!

Subject: Flying & Stuff
To all, I got in a hour or so today after I changed out the half doors for the full doors and enclosure. I felt like I was in a spam can again... almost. The visibility was limited with some foggy scud clouds and the overcast was at 1.5K' - 2K'. The wind was not a big factor. I don't think I would have flown in unfamiliar territory today, but I know that area very well so up I went. I did a circuit at my home airport and then flew over to a lakeside airport about 15 miles away to practice on their grass field. On the way over, I checked the GPS against the ASI to see if changing the doors had made any difference in the indicated readings... no difference, but still way off actual... no matter. I have been careful to try to run my rotax at least 5800 rpm (as suggested by J.Hauck). That "putts" me along at about 70 mph... depending on how trimmed out I am and how rough the air is. Today, the air was relatively stable considering all the cloud activity... no sunshine to cause convection currents I guess. When I got back to my home airport I made my first 1/2 flaps landing. I was pretty high on final and rather than just dump the altitude with the flaps then retract before landing I just left the flaps deployed. I kind of liked the extra drag and shorter float they provided. Now that I have over 50 hours, I will begin to experiment with them some. I checked the main wheels and they needed tightening... one side only 1/8 turn, the other 3/8 turn... to bring them back to "non-wobble" "not-tight" snug. I also tightened the cable brakes a little. I needed a little more stopping power. After all the talk about hinges, I oiled mine a little. Talk about quick light ailerons now... sure, dream on... I discovered a screw up on my part and I have no idea how long I have been flying this way. The last time I loosened up the wing gap seal (probably to take off the rear enclosure last spring) I failed to slip the hold down hook into the tube that holds the center rear portion of the gap seal down. I have been flying that way for awhile with no problem. I could see where the hook had rubbed paint off the tube and where the gap seal had risen up to touch the muffler (I have an aluminum plate there to protect the Lexan from melting) and other engine parts, but the rear springs did their job as well as the "hook" and held everything in place. I gave the radio some more use today and I am very satisfied with the clear reception from other aircraft. I feel I am transmitting pretty well now, but so far have only tested once. Whatever... nobody was complaining today. Enclosing the Kolb does reduce the decibels due to wind noise... maybe even the engine a little and probably helps my transmissions. Shielding the plug wires helped some I know... no more stacato noise rising and falling with the rpms. Getting a good headset adaptor made all the difference. I am a happy camper... -- Cliff & Carolyn Stripling Him: Retired Pharmacist (972)247-9821 Dallas Texas Her: Real Estate Broker - Texas and Marble Falls Texas Both: 5th Wheel - RV - Travel Kolb MKIII - N582CC (50+ hrs) ________________________________________________________________________________

Gentlemen, I would someday like to see a study done on 2-cycle vs 4-cycle reliability. I think at this point in history, the 2-cycle would really give some startling aviation statistics as far as trouble-free hours for the amount of time flown. Carbon buildup will always be the downfall of these engines, but now that we all know about Seafoam and other such additives, these little hummers could really tip the scales on the fours. I'm impressed with all the hours flown by you guys and others using the 2-cycle. The four cycles do fail too, even those expensive Lycomings, because they have many more parts that go wrong. Maybe there is something to be said for simplicity ....... it means reliability. Ralph Burlingame Original FireStar, 447 powered >Definetly a factor, but 2-strokes can be kept pretty reliable.

When you carry the wing in, ease one end of the wing over the level hanging tube. Then go to the other end of the wing, where the pvc is hanging vertically, and swing it up level to support the wing, and slip the loop over the end of the pvc tube. Done. Caution!

If it is running it is reliable. If it ain't it is unreliable. Most of the problems I have had with either type eng was my making, or failure to check what someone else did. Two stroke was sparkplug wire falling off inverted Cuyuna, paper fuel filters, fouled spark plug. 912 only quit when I got a couple gals of water with 10 gals of gas and I failed to drain fuel prior to takeoff. Course the eng didn't stop on the ground, it waited til I was most vulnerable, a couple hundred feet in the air in a hard climbing turn. Was able to get her turned 360 deg and land where I had just departed. Lake Texoma, Texas, last Jun, got the first ten gal of fuel from new fuel tank, filter, pump, hose and nozzle. Was lucky, didn't lose eng until about two hours eng time after refueling. Fuel filter packed up completely with debris, shut off fuel supply and eng twice. Lucked out and got it on the ground again successfully. Only time the 912 everstopped in 985+ hours. Had a 582 seize, never determined cause. This type failure bothers me more, when it comes to reliability, than flying with the 4 stroke. Haven't heard of any 4 stroke siezures. This 582 seizure gave me no warning signs, feel, sound, or instrument readings, no clues that it was impending. I still fly 2 strokes and don't sit on the edge of the seat when I fly them. They have given me good service and reliability. One of the biggest factors to fly a 4 stroke is economy of fuel, oil, sparkplugs, and teardowns. If one flies enough it will make up the difference in purchase price with economy. Yes, if it is mechanical it may break, no matter what it is. Was taught in flight school to always have a forced landing area in site. Still an important safety factor. john h ________________________________________________________________________________

As an interesting aside on 2-stroke reliability, Duane Cole's video, "VFR tips for all pilots", has an interesting segment wherin the Ol' Master Hisself advises that he always flys evaluating the terrain ahead so that given the choice, he has a good flat field within gliding distance in case his Expensive Genuwine Certified Aereoplane Engine quits. And he says he normally alters his flight path right and left to give himself an out just in case. Maybe that puts things in perspective?

Subject: Re: Engine vibration-The answer is:carbon ?
Date: Nov 24, 1998
Hey Bill, Well, being you cleaned your prop but it's a wood prop, when did it get wet or when was the last time a front came through your place or did you leave the prop vertical the last time you flew before you noticed the vibration? It's funny how one answer can lead to a whole lot more questions ain't it? I don't know about the snowmobile oil your are using but I bet if you were to switch to Pennsoil 2 cycle air cool oil and run it a little harder it wouldn't have a carbon problem. I use to the same problem with a different brand that works great in a lot of other engines but I always had a carbon problem too. Then I called John Hunter at Lockwood to find out what they used in their 582's. He told me that Rotax recommends Pennsoil (air cooled) in all there aircraft engines regardless of whether it was air cooled or liquid cooled because of the way they are run ( long periods of sustained and steady RPMs and similiar temps). This was after my brother had put some 800 hours on a Lazair with the 9.5 HP Rotax's using Pennsoil with out a rebuild. Then there was my wingman Richard who has always used the oil and has never had a problem. I wasn't satisfied with the evidence that they gave me either. I had to try something different also. Guess what ? I was decarboning every 100hours or less. I probably should have done it at 50 hours. I have 250 hours since the top end (this is where I started using Pennsoil) and it is still going strong without a decarboning. I don't have any of the other problems that goes along with carbon buildup either like hard cranking from the rings being stuck on the pistons and smoot black plugs, which I had to change a lot more often. Richard had even gotten to the point that he would not even crank his plane around me until he was sure I was cranked. I spent many times hand proping while he held my plane. We've not had to hand prop but once and that was from a dead battery since I switched. I am convienced it was the switch to Pennsoil. I also use the injection system that is still set from the breakin. How many hours do you fly and how often? Did you know that wood props absorb water and that it can migrate to one end? I have a wood prop I use as a spare. In case of emergency only. I know it is as balanced as I can get a wood prop but compared to my IVO it can't hold a candle to the smoothness or quietness. The whole plane benefits from the lest amount of vibration that can be run. That old wood prop liked to have beat me to death on our trip to Nulltown, In. last year while the IVO was being repaired. After that trip I decided to stay home if I couldn't have the IVO. I know there are pros and cons to all of this and would like to hear from the rest of you. Who knows there might be something out there you are using with great results and we would all benefit from it. All for now. Thanks for the return.

This type failure bothers me more, when it comes to reliability, than flying with the 4 stroke. >> John: You get alot of respect on this list and you deserve it. But let me offer the following. Again, it is NOT my intention to give you a hard time. Several years back at lakeland I was doing my annual tour of the certified rotax repair guys' tents. Every year I go talk to these guys and ask them about the failure modes they have seen in different engines, principally 582 and 503 because that's what I fly. My experience is that engine rebuilders are a much more reliable source of good information about failures than pilots themselves. Anyway, the guy from Greensky (I think) offered to sell me a brand new freshly rebuilt 582 which he said had something like 5 hours total time on it. I said gee, why was it rebuilt after such a short time? The guy knew I was a Kolb pilot, and he sorta shuffled his feet and said well, one of your better known kolb pilots seized it up. I said jeez, how did he do that? The guy replied, well, this pilot thought that Marvel mystery oil was good stuff, so he put a little in the gas. That worked out good so he decided to put a little in the injection oil. Well what most folk don't know is that marvel mystery oil is mostly solvent and perfume with a little high grade lubricant. The pilot put in enough that it screwed up the oil/fuel ratio and he seized the engine due to lack of lubrication Anyway, he said that guy was you. PLEASE DON"T ANYBODY SHOOT ME!!!! I'M JUST REPEATING WHAT I WAS TOLD. However, even if this story isn't true (which I repeat it may not be) there is a lesson to be learned from it. We are all tinkerers or we wouldn't build our own planes. Every kolb owner has customized his plane to some degree and as his own way of doing things. This is fine except that there are limits to how far we can deviate from "doing it by the book." There is a whole category of accident which happens in this category of plane which doesn't happen in GA planes. Example: a guy a my field with an early firestar found his plane to be nearly uncontrolable after he changed the frame tubing around and moved the gas tank to "make it look cooler." When do you think the last time was that happened with a c-182? My point here, and I think I'm in agreement with John, is that when it comes to operating Rotax engines most of our wounds are self inflicted. ________________________________________________________________________________

I have never lost an eng when I expected it. It always comes as a complete surprise. In the days of 2 stroke flying I practiced what I preached. I think the fact that the 2 stroke quit more frequently made a better pilot out of me. Also in those days my XC flying was done with mag compass and sectional. That also made a better pilot out of me. Today with the GPS I get lazy because it is so reliable. I try to keep up with my progress on the sectional most of the time. Coming out of Kankakee, Illinois, to Joliet and Oshkosh this year I lost the GPS. Shocked me right back into the real world in a flash. I had to fly pilotage and dead reckoning to Joliet before the GPS decided to cooperate. After I got settled down to busy, I realized I had been missing out on some good flying. All I had to do was watch my airspeed and altitude, read my sectional and follow my route on the ground, as I cross checked the mag compass. I wasn't worried about ground speed, ETA, or staying precisely on course. Given the choice though, I'll fly with the GPS as primary nav aid. It saves time, gives me a lot of emergency options, and makes my XCs safer, which translates to more longevity and the opportunity to continue flying. john h ________________________________________________________________________________

I said gee, why was it rebuilt after such a >oil/fuel ratio and he seized the engine due to lack of lubrication Anyway, he >said that guy was you. Hi Gang: I think you are talking about Gerry Olenik, owner of the oldest Rotax dealership in the US. I've done business with him for years, however, Gerry didn't get involved with my 582, except to sell me pistons, rings, and gaskets to rebuild it. I had over 200 hours on this eng, flying to Lakeland, Homer's in Pa, and Oshkosh. This was a new eng I got from Homer when I built the MKIII. Flew it the same way during its entire life, with Marvel Mystery Oil since day/hour one. Seems to me, if it was the MMO that caused the seizure, it would have happened early on. Put about 1200 hours on my Cuyuna and 447s, all with that shot of MMO. The 582 is the first and only 2 stroke I have ever seized, including a fist full of MX bikes, outboard motors, and my weed eater. I swapped the 582 for the 912, but I went south instead of north to do it. I dealt with Ronnie Smith. I guess stories like this are part of the little bit of notoriety I have gained over the years. I think I mentioned in a recent post that I doubled up on MMO for my flight to Quincy, Fl, and return. The 912 has ingested a lot of that stuff over the hours, also my Dodge Cummins Diesel, Onan generator, and the 351W eng in the old Searay. I swear by it. I wonder if it would work on my arthritis??? hehehe Did you guys know if you keep a four stroke eng bogged down, running below the power band, that it will carbon up, get cranky, lazy, and weak? Don't you know how much better the old buggy runs after you take it out on the Interstate and blow that sucker out for an hour or so. Two stroke engs are just like deem 4 stroke engs when it comes to getting clogged up with carbon and gunk. I read on this list of making these poor little engs fly around at 4500 to 5000 rpm their entire life. Then when they get gunked up with carbon, cannot figure out what they are doing wrong to cause this terrible condition. It is pretty simple to me, it is your left hand, the one you have on the throttle. The rotax 2 stroke is not a tractor (farm) eng, it is a high performance, high rpm eng that spends its entire life loaded/going up hill all the time, even when it is idling. It has an expansion chamber exhaust system that is designed to make the eng efficient, both power and economy, somewhere after 5300/5400 rpm. I always found with the 2 stroke (Cuyuna, 447, 582) that they all like to run 5800 rpm cruise. At this rpm they are smoother and the internals will stay significantly cleaner. OK, I can only talk, with experience, about 2 strokes up thru the early 90's, but I bet they haven't changed all that much since then. Just my own thoughts and experiences friends. This ain't the gospel, but it has worked for me, and it is still working. If it changes, I'll let you know. john h (Hauck's Holler, Alabama, still got those leaves and pinestraw to rake up, ugh!) ________________________________________________________________________________

Hey Ben. If you guys are Kolbers does that make me a Ferber? Amen on the bigger picture Ben. I can relate from my on experience that an engine out at altitude is a lot more forgiving than one at low altitude. The options are much better and you have time to think, what the best coarse of action is. That difference in time can make the difference in whether or not you make it or break it. In my training course , I try to instill into my students to always have a spot picked out within the cone that the airplane always sits on in flight. The outer edge of the cone is at a 45* angle down from the plane. It may be overkill for some pilots but this will usually work on any airplane. I believe in the "WHEN NOT IF " saying about engines, all of them. Just the other day a student pilot an his instructor had to put down on a county road north of here because the Lycoming in the C-150 quiet. Funny thing is I had to practice emergency approaches on that same road when I went for my private. I'm getting like John about this stuff. It's almost addictive. I wonder if there is a support group for E-mail addicts on the "Internet". All for now. Firehawk. P.S. I definantly agree with the MMO that John uses. I use it from time to time as a gas additive. Sure helps to keep thing clean along with Pennsoil. But I don't mix the two, something a Pennsoil Rep. said one time " It may or it may not mix but do you want to take the chance?'' I think he was refering to outside temperatures and the way the viscosity is different in the two oils not readily mixing. -----Original Message----- From: Ben Ransom <ransom(at)mae.engr.ucdavis.edu> Date: Wednesday, November 25, 1998 10:43 AM Subject: Re: Fw: Kolb-List: 2-stroke reliability > >On Tue, 24 Nov 1998, David Bruner wrote: >> That's easy for you flatlanders to say.

I am just wrapping up the covering of my MKIII and was wondering where I should install inspection rings to be cut out if needed. I was going to put one where the drag strut meets the steel rib, but other than that I cant think of where else I might need one.

On the other hand, I think there should be *some* holes and covers to be able to look inside. I installed 2 rings/holes/covers on each wing: - 1 on the bottom of each wing where the lift+drag struts join the main spar -- a key spot to be able to get a visual on at annual. I just love to look at that home-made AL box where they join cuz it is so impressive how you can get so much strength out of thin AL (!). Also, I could get a wrench on top of the big spar bolt if I needed to (or somebody with small hands could). - 1 on each wing root just behind the main spar to peek in on the drag strut and it's steel braces. For the wing root, you could cut it and patch it annually but rings seem more the right way to do it.

David (but I'll find out fer sher when I get up there) Bruner >> David, what I meant by "flying by the engine" was disregarding some common sense dealings with the hard spots, namely the ground, or other hard barriers. For instance, when you fly near the "granite" (mountain, hill) it would be adviseable to stay on the windward side to take advantage of the prevailing air currents for lift, just in case the engine did quit. Instead of coming in for a landing at a constant 1.3 degree declination like a GA plane might at a big airport, stay high enough to always be able to pick an alternate landing point , until you finally clear the final impediment or barrier such as telephone lines before "aiming at the ground" or slipping to the ground. Yes you will land hotter and longer but always safer.(unless of couse you blast yourself into the woods at the other end of the too short runway!!) I think I hate that when that happens. Know the wind strength and direction at all times to be able to estimate how far you can glide if the engine quits now....no, I mean ....now. My L/D is 7.9:1 on an engine idle ( therefore it is probably better than that when the prop stops completely), therefore I can go almost 8 miles on a dead day if I'm up one mile, and that is like money in the bank for engine failure. ..................GeoR38, the ol glider pilot ________________________________________________________________________________

Met a guy that trailered his Kolb all over the place, and he said if he had to do it over again, he would have made his trailer so that the wings hung on the sidewalls. Seems that the leading edges are so close to the ground when it is folded, that they can readily drag when you go over a hump, or where a ramp meets the trailer. His leading edges were kinda beat up. I am glad I did not provide for my wings to fold, so that I am not tempted. Besides, empty weight is 513, with 15 gallons of fuel, it is over 600 pounds. Trying to push that across the back yard to the garage would wipe the Old Poops out. It is heavy enough with the wings off. Besides, the only time I put it in the garage is to do maintainance.

When I built my Original Firestar I wasn't aware of the aluminum replacement for the fiberglass tailwheel rod. However, now that I am flying it I see that the replacement is needed because the tailwheel flexes sideways when turning. My question to the group is: What is the best way to remove the epoxied-in fiberglass rod? Naturally, I don't want to damage the lower fin in doing so. The use of heat is out of the question so I assume I'll have to cut off the rod near the lower fin and drill a pilot hole as close to center as I can. Then follow that with progressively larger drills. Is there some other way? Thanks, Ron Carroll Original Firestar ________________________________________________________________________________

Crisp with radiant blue sky, little wind and I had to leave on a flight that afternoon so couldn't attend. My partner flew our FireFly in and had a great day. Gene, one of our buddies on the field missed out on the fly in. Seems he suddenly developed noise in his engine (a 447). Later found out that one of the brand new spark plugs had broken off some porcelain near the electrode. Put a new plug in and the noise went away for a little while. He ended up pulling the cylinder and found the broken hunk of porcelain in the cylinder. It had beaten up the piston top, which he smoothed with a dremel tool. He's ready now to test fly it.

If a piece of porcelain beat up the top of the piston, it had to have something to beat on, and that would be primarily the cylinder head, and possibly the top ring. Depending on the severity of the damage to the top of the piston, I might have considered replacing it with a new one. Dremel tool equates to grinding and grinding equates to loss of mass and weight. Might prove to be a problem. I used to balance my pistons, rings, wrist pins and bearings. There was always enough difference in their weights to make a difference in the vibration level of the 447 and 582.

Hey Bill, Sounds like you got it under control. If you call the Pennzoil people they will put you in touch with some one in your area. 70 hours a year, huh. I can see you are a dedicated flyer when you have to drive all that way and then set it up.I must be one of the few that is only 5 minutes from my plane. I use to live 10 minutes but that was to far and it took too much time to get to the airport. So I built me another house closer and then sold the other one. Now I,m thinking about building a house on a new runway north of here where I can just walk out the back door and get in the plane and go. I dream a lot too. Bill, I have a wood prop that I use as a spare and another that I have on my Fisher 202. I have never been able to balance them satisfactorily. Would you mind telling me how you do that ? I bet there are a lot out there that would like to know. I've used prop balancers and they don't seem to give me the balance I am looking for. There is always this low frequency vibration that can only come from the prop. I guess I'm spoiled by the smoothness of the IVO. I was out flying around this afternoon just checking that bolt I torqued for maintenance, I am just amazed sometimes how good it feels to be able to fly. It was so smooth and no one else around. John H. mention that he uses Marvel mystery oil in his mechanical things, I do too, mostly the Gas add treatment. My Dad used it in all his machines too, way back in the 40's and 50's when we used to run a sawmill in Southeast Georgia. I was only 4 or 5 years old when I was introduced to it. We had our share of break downs but they weren't usually from the engines we ran. I remember when my brothers bought the old sawmill from Dad they used the same old Red Seal power unit flat head 6 cylinder, gas ) that ran the mill originally. That was some 20 years later. After a little cleaning and adjusting the old thing could be hand cranked in one throw. It came with a built in crank handle just like the old Model As. I remember being so small that I could hang on to the crank and it would only move as the compression leaked down. Man to me that was a long time ago. The old place we grow up is a car lot and a mall now. I used to fly my U- control plane where the mall parking lot is. Listen to me rattle on. We were talking about planes. I hope that one day we can all met from time to time. It can happen. So many stories to tell and so little time to tell them.

We ran into a few questions...There is no suggestion on what to torque the nuts to on the aluminum plate that attaches to the crankcase, or the bolts/nuts that go through the Lord Mounts. I read all pertinent material a thousand times and I couldn't find any #'s...So has everyone else just tightened it all up until you feel like it will stay connected in flight, or is there some magical ft/lb # that we should be aiming for?

For torque on regular nuts and bolts (steel on steel) you can look in a good repair manual (such as chiltons, or for you engineers out there, "Machinery Handbook") and it will have recommended torque tables. Remember, a bolt and nut is actually a clamping device, so the torque is specified to obtain the maximum practical clamping force without straining the bolt shaft (or threads) beyond the yield point of the particular alloy. For accurate work, oil threads before torqueing. Paige Straley ________________________________________________________________________________

Tom, I hate to get argumentive, but I've built quite a few engines, and have always read to " Make sure threads are clean and lightly oiled. Torque to spec with a quality torque wrench." Never, ever had any problems. A small thing to try is to thoroughly clean a head, block, and bolts. Torque one down dry, and focus on how it feels as the pressure comes on. The next one, LIGHTLY oil it with a light oil such as zoom spout, which is a 10 wt non-detergent turbine oil, or 3 in 1. NOT WD-40 ! ! ! Torque it down. You can literally feel the difference. Try it, you'll like it. Big Lar. ---------- > From: Thomas L.

Hi Group: I forgot to say that oiling threads works well, but the last few engines I've built, I've used Bostick Anti-seize lubricant - lightly. Torques down smoothly and years later comes loose without binding. Works especially well on exhaust manifold bolts. Haven't had any problems I can think of with coming loose prematurely.

Subject: 2 stroke motors
Date: Nov 26, 1998
Hi All: For all this time I've been reading engine diagnosis notes with some interest. Most of my experience has been with 4 stroke engines, but for 7 years in Idaho I felled timber with a Stihl 051 AV chain saw. I realize it's not a Rotax, but it is ( was ) a 2 stroke. You may believe me when I say we ran those motors VERY hard. No danger of crashing, just grab the spare saw and fix the 1st one that night. What I remember tallies for the most part with what I read here. One way or another, seems like we spent an awful lot of time fiddling with those little Bing carburetors. ( Bing I think, made in Ireland at any rate ) Probably the second most severe problem is one I don't recall seeing much of here. That is a main seal sucking air, especially the drive side. As it started, the symptoms could drive you crazy, very hard to pin-point. As it worsened, it would get more serious. On a large tree, 4or 5 or more feet thick, which makes for a long, hard pull, it could suck enough air to lean it out, overheat and seize the piston. Also seems like that was about the only time we did seize up. Is this a problem on Rotaxs ?? Or have they figured a way around it ?? Just noodling.

I agree with Larry Biglar about his suggested experiment--try the difference with an oiled thread and a non-oiled thread. One problem is that you can't really de-oil metal without washing it very thoroughly. For the non-oiled test, wash with really hot water and a strong detergent ("Dawn" brand picks up mineral oils best, in my experience), dry with a paper towel and follow with an acetone rinse. There is a difference, and you can measure it! Agree also with Biglar on anti-sieze, especially in high temperature connections where the oil will cook off, and also on steel bolts threading into aluminum.

Wally, I would say the answer to your question is "no" the wing tab does not need to be centered. Whether the tab is centered or not mainly depends on how the cage and the TE universal joints are welded up. Since nothing is perfect and the flight characteristics of your plane will not be appreciably changed with the tab in the center, no need to worry. What really matters is getting both wings at the same angle of incidence and this is determined by the placement of that hole that you drill in the tabs and the one in the fork of the cage.

Before you drill try heat. Most of the 5 min epoxies soften up pretty quick with a bit of heat. If you have time a hairdryer may work but a hot air paint stripper would be best. A torch would also work and you don't need it as hot as you would think. Try this first. If it works it will be easier than drilling.

BTW, I've been flying off the >replacement fiberglass rod for about 10 years. > Good point. Unless abused, a fiberglass rod should last a long time. About the only thing that does them in is allowing the aircraft to sit with wings folded, with all the tail weight being taken by the tailwheel. The fiberglass rod under such loading will slowly twist until the tailwheel is lying flat on the ground. If you have a fiberglass rod and fold your wings, you should place blocks under the folded wings to take some of the weight off the tailwheel and rod. The fiberglass rod is actually a better spring than the aluminum, but we discontinued using them because of the twisting with folded wings as mentioned above and because of the difficulty of replacing the rod in the instances when it is damaged. Some have tried drilling and bolting the fiberglass rods in place. This further reduces the twisting strength of the rod and typically such installations will fail quickly.

It is not too good, but it is not too bad either. My 532 used about 1/8" of oil out of the little bottle every 3 or 4 hours. It had done it for over a hundred hours, and is starting to taper off lately, and is using less. If you have a main seal leak into the crankcase cavity, so that the oil reservoir for the crossover shaft is leaking into the crankcase cavity, the system can become pressurized at full throttle, and will start to blow oil out of the little bottle. Obviously you need to shut down ASAP. This can happen when people disassemble your engine and put it back together with RTV instead of the listed Locktite sealer. I bought a used 532 for my J-6 several years ago, and this was the situation. Use only the Locktite specified in the shop manual, or on the CPS/LEAF parts pages and it will seal. It is important to seal the oil seals around their perimeter to the crankcase with the Locktite.

Hi Wally: What's important is that both wings have the same angle of incidence and that you have plenty of edge distance. Set everything up and and check everything over several times before you drill. If you're not going to be folding the wings, make bushings and bolt the wings on. It's been a beautiful weekend for flying and I've still got two days to go!

Subject: Wing Spar Attach
Date: Nov 27, 1998
Thinking about Wally Hoffman's question on the wing attachment - I set my Mk III up absolutely level, without the wheels and tires, and bolted it solid to the floor. Stretched parachute cord tightly from wing tip to wing tip - leading edge and trailing edge, used levels, tapes, rulers, shims, and so on till I was darn near confuzzled. Then walked away for the day, came back the next and double checked everything. Once those holes are drilled you're done. No adjustments. Now, after reading other comments ( I think from John H. some time ago ) I wish I had somehow made provision for increasing dihedral if necessary. Not sure how you would go about that, but it seems like it would be desirable, if only to fine tune the rigging. As it is, when you drill the struts, that's it.

As it is, when you drill the struts, that's it. Big Lar and all, Yep! I would imagine that of all the airframe parts in flight the lift struts get a lot of stress (in tension anyway). I don't think I would want some kind of telescopic mechanism in it that "possibly" could come loose or fail. It took a long time for me to convenience myself that the clevis pins connecting both ends would be strong enough. After looking at the video of the Ultrastar, Flyer (or whatever the early version was) doing loops and other aerobatics, I figured I could fly safely "not" doing those maneuvers. Something heppened to me entirely by accident in rigging the main wings. Before I raised the wing tips for dihedral the leading edge was not perfectly straight. I wanted to make sure that I had enough metal on the outer edges of the main wing attach tab holes and therefore I drilled the tabs so that the wing tips were a tiny bit forward of the inboard ends on each side. When I raised the tips the required distance (1" on each side if I remember), then the leading edges viewed from the side were perfectly straight. The fact that the wings have the different angle of attack vs. the fuselage caused the wingtips to move to the rear a little as they were raised. As far as rigging and how it flies is concerned, it probably flies as well whatever the small sweep of the wings. So far, I have never felt I needed more dihedral than what the plans called for. Once trimmed up it does not seem to have any tendency to want to roll off to one side or need any more stick attention even in turbulence than did Cessnas of my past experience. Rudder on the other hand is another subject. I would recommend everyone adding a yaw string (primary flying instrument) and the rudder trim tab like the plans addendum recommends. I have not yet because: (1) I am lazy (2) my rudder looks too pretty to mess up now and (3) I don't mind riding left rudder most of the time.

The twist with epoxy only had finally failed when I left my plane out in front with the wings folded on a strong north wind day. The constant side load finally worked it over and I was glad to have it happen right in front of my garage instead of parked at a public strip. I drilled a 3/16 hole thru, as far up the sleeve as possible and still catch the rod. I guess I'll see how long this lasts and not be expecting much. One note from my build on the engine mount torque subject. When I bolted each Lord mount to the airframe I found on the first couple bolts that I easily over torqued them. Some care is needed here as these are small bolts (AN3), and the little voice in my head was thinking "get these tight". Easy to over do. I changed up to AN-4 so I didn't have to fret about having left in over-torqued, weakend AN-3s. -Ben Ransom http://mae.ucdavis.edu/~ransom ________________________________________________________________________________

When we drilled them initially, we (my machinist brother-in-law & I) spaced the three holes at each end evenly apart. By removing the bolts and sliding the end fitting out one hole's length, we had two holes in the end fitting that lined up, and needed one new hole through the fitting. Used the existing hole through the strut as a guide to drill the new hole through the strut end and was all set. HOWEVER: I could tell no difference with 0", 1.75", or 3" of dihedral in the wings. Asked J. Hauck about it at Oshkosh, and he laughed, said I would never get it to fly hands off. He was right. It currently has 3", but I will put it back to 1.75" this winter. IMHO, you only need just enough dihedral to make it "look good". Richard Pike MKIII N420P (42oldpoops) ________________________________________________________________________________

Talk about great minds running in the same circles. I've looked at those same pins with exactly the same thoughts. It's fairly easy to rationalize to your mind. It's a little tougher to talk to that little monkey scampering around in the back of your head. ( or your id, or subconscious, or back brain or whaddaya wanna call it. ) I agree about the tension on the struts, and that's why I don't know how I'd go about it. I guess if you're off enough to matter, a new end fitting and re-drilling would be about the only safe answer. What bothers me the most is the gap at the lower end. Seems like it would have less stress if it was set up like a close fitting mortise and tenon, rather than the bending moment it has now. I bought a worm gear window opener some time ago, and am planning on putting a lever or crank on the output shaft and hooking it to the rudder return spring. Have to have a limit stop too, in case the winder breaks. It'll give variable tension to the spring, which should work out about like the elevator trim springs. I like the way trim tabs work, for sure, but I don't like the way they look either. Also prefer adjustability for different conditions. Thanks for the reply. Your input has always been very good.

All of the folded weight is on that tailwheel. When I installed the rod 10 years ago, I got some epoxy for free from the research company that I used to work for. At the time, I told them that I needed the epoxy for a tailwheel of a plane. I didn't say that it was for an ultralight. I did get some "raised eyebrow" looks.

I didn't say that it was for an ultralight. I I used PRC on mine. Outdated from the American Eagle maintenance place my brother was working at at the time, but still plenty good. Shlopped a bunch in the tail tube and the tailwheel assy, stuck in the glass rod, and said to myself - I'll need to build a new tail section if that ever needs to be pulled out. :) It has ~4 years on it sitting in the garage, full weight of folded wings. I just remembered, that when it twisted over last summer, the part that twisted was really the tail wheel assy, not the front-end inside the steel tail assy. I added the AN3 bolt to both ends although at the time I still thought it unlikely the front end would ever ever budge. Dennis, if I ever order a new tail ass'y, you will know that it finally gave up. :) -Ben Ralph, I liked your bit about changing the Cub pilot's opinion of ULs last flight. I'm vain enf to think we Kolb owners do that quite a bit. My last time out too, a 172 owner was asking me all the wannabe questions and lamenting the $6k he just sunk into his plane for a full paint job. He said it will never look better so maybe he'll sell now and get something like ours. Another funny side thing I noticed: How long does it take to unfold a Kolb? ...About as long as it takes to gas up a a 172. Honest, a couple months back I was starting to set up as a 172 pulled up to the self service pump. I was putting in the last pin when I notice him starting up and leaving the gas pit. course I needed to gas up too, but I had already done that the evening before at home. I am starting to envy his cabin heat tho! ________________________________________________________________________________

Every time a spamcan driver walks by my FF and laughs/smirks, I "sweetly" tell him he's just a medical away from a UL. They get kinda sober then. And I laugh. Grey Baron ________________________________________________________________________________

Lar , wouldn't increased dihedral be a funtion of longer struts as the wing attach points either pivot or are universal joints?? chris -----Original Message----- From: Larry Bourne <larrybiglar(at)earthlink.net> Date: Friday, November 27, 1998 11:34 PM Subject: Kolb-List: Wing Spar Attach > >Thinking about Wally Hoffman's question on the wing attachment - I set my >Mk III up absolutely level, without the wheels and tires, and bolted it >solid to the floor.
