P.S. I haven't started the RV yet. Just dreaming of it. Bill ----- Original Message ----- From: Ian Heritch Subject: Re: Kolb-List: safety harness Hi Bill, Believe it or not, I intended to email you today with a host of questions. Last week I finally finished painting, man what a job. I am so glad that is over, I cannot imagine putting forth the effort you did to achieve your fabulous finish. I have begun working on the gap seal. If you don't mind, I plan to copy your gap seal fabricating it from sheet aluminum in order to use it to hold the oil tank. Do you remember what guage sheet aluminum you used? I see you used angle to give it strength. Where did you find the plastic black groments, and what did you use as the edge material? Also, did you fill the gap between the bottom of the wing and the cage? It is a good size gap, but the construction "pamphlet" (Irefuse to call it a manual) doesn't address it. Go figure. I understand you are building an RV-8, hope its going well. I co-built an RV-6 several years ago. In hindsight I think the RV was easier more enjoyable to build than the Kolb. I did not like the fabric. As always, thanks for your help I truly appreciate it.

Hey guys, this horse has been beat to death! -but what the hay, it's been slow here lately. When it comes to best angle of climb you can just throw that VSI out the window, no connection, nohow. My old barebones Aeronca with skinny me, low gas, cheater A-65 with A-80 pistons swinging a 74-43 at 2300rpm would climb like it was on a cograil track at just above stall. Great fun in a dogfight because you could stay in a small arena while your opponent (citabria or whatever) had to travel horizontally. As soon as you saw him below, you could kick rudder and nail him.

Kolbers - Yesterday, on the first day of 2002, I started the Verner engine on my Mark-3 for the first time. She breathes ... she LIVES ! And oh, what a sweet sound it was! I only ran it for about 10 minutes, and I'm happy to report that my experience was much less eventful than Big Lar's first engine run of last month. Pretty much, everything worked like it was supposed to (tach, oil pressure light, oil temp gauge, elec fuel pump, voltmeter, no oil or fuel line leaks etc.) except one thing: One of my CHT needles never came off the peg. (Have to chase that down.) The outside temp was 31 degrees, so it took several turns before it finally started, but once running, the engine ran smoothly. Sounds like a Lycoming, with each of its two big cylinders putting out 700 cc. Only went up to 3400 engine rpm (half that in prop rpm), but the swirling snow storm behind the plane kicked up by that 72-inch Powerfin prop wash was impressive! (Max continuous engine rpm is 4000.) Now, with that major milestone past, I'm looking forward to beginning taxi tests soon. Dennis Kirby Cedar Crest, NM ________________________________________________________________________________

Also, I installed a custom windshield yesterday. It is a partial enclosure with no doors. The coverage is about to the shoulders so one must slide in from the side. The interesting thing is the way it flies now. I always operated at a VERY aft CG range and always had to hold some forward stick. I never wanted to add a trim system for the sake of simplicity so I just lived with it. The new windshield, however, has me flying hands off and at faster speeds, holding AFT stick. What comes to mind first is perhaps a downward planing action from the windshield. If this is the case, it must be a powerful force on that Lexan. Also, my speeds jumped up 10-15MPH. I need to run some tests to see if its a net gain or just an new low pressure area behind the panel playing with the instruments. I will get some pics of the windshield on the site soon.

Hello Kolbers, My first engine out landing came at 186 hours with the pulse line breaking where it attaches to the engine..(recommend annual replacement for a buck and a half) My next engine out came in less than a week from the first and I have not figured that one out yet. I had flown for an hour or so with no problems but when I set up for glide to landing on final, as soon as I pulled the power back the engine quit. I managed to get it started again on the ground but it would not run at idle. I figure it's time to decarbon anyway so I am planning to tear it down as soon as the weather warms up a little. Nothing else was obviously wrong including float bowl, wiring, plugs etc. I had recently changed out the plugs with another set of the same type I had been using and also changed out the spark plug caps with the metal noise reducing types but they had been run successfully for several hours before this event and they checked out fine. This is a 503 Rotax with single carb and points ignition. I have been trying to copy and print (from the CPS site on the internet) Mike Stratmans article "What To Do When It Quits" which was published in Ultralight Flying but the reproduction is poor on the site. Does anybody know where I might find a pristine copy of that article that's clean for copying?

Steve, Others have more experience than I, but for a 2-stroke quitting on idle I would be suspicious of air leaks, especially since you are getting spark all the rest of the time. First tho, it is pretty easy to check the carb idle jet is clear to rule that out. Then, remember that problem air leaks can be on either intake or exhaust manifold (or other more troublesome, but unlikely spots too). I had created a simple no-cost leak down test method so let me know if you want info on that. -Ben Ransom --- Steve Kroll wrote: > > Hello Kolbers, > > My first engine out landing came at 186 hours with the pulse line > breaking where it attaches to the engine..(recommend annual > replacement > for a buck and a half) My next engine out came in less than a week > from > the first and I have not figured that one out yet.

This is a 503 Rotax with single carb and points ignition. Steve, There is an old discussion about running high resistance plug caps (over 5K Ohm) and resistor type plugs together with points ignition. We avoid that because the voltage is not that high anyway with the points set up. I did not catch wether you had resistor plugs also,, but the voltage can be right on the edge,, and hard to start after just a few hrs. on the plugs. I believe resistor plugs and up to 5K Ohm caps are ok with CDI ignition. Just thinking out loud,, Tim Townsend ________________________________________________________________________________

Subject: Re: engine out
Verify if it's fuel starvation related - do you have a primer (not the squeeze bulb) - can you keep it running with shots of prime? Since you messed with the pulse line, one did you replace it with the right stuff - thick walled so the tubing will not collapse and cause soft vacuum pulses to the fuel pump. Next is there any possibly a air leak - poor clamps - next did you replace the line. Fuel pump installed with the vent hole in the correct orientation. Have you had the carb apart and reassembled it correctly - the needle, clip, and that plastic thingy must be assembled in the correct manner or it will not run right - wonder how I know this (red face). <:') Do you have a squeeze bulb, do you have it bypassed - if not it check value could be sticking and at lower RPM the fuel pump may not be able to over come it. Have you had the fuel pump loose where it could have been reinstalled backward to the fuel flow direction - moving it may have shifted debris plugging it. Last, any chance you have some water in the system - doesn't take much - they normally will run with water at higher power settings but often will not idle well. jerryb > >Hello Kolbers, > >My first engine out landing came at 186 hours with the pulse line >breaking where it attaches to the engine..(recommend annual replacement >for a buck and a half) My next engine out came in less than a week from >the first and I have not figured that one out yet.

I'm sure there must be something my method lacks, but it has been 3 years since I did this so I don't recall -- others feel free to jump in. When I did mine, I felt it was impossible that I had a leak on the intake manifold side. That stays clean, is bolted to clean new gaskets, and everything is smooth as a baby's behind. So, assuming that needed no checking, I took off the intake manifold and made a cover for each port out of 3/4" particle board. I used the kind that has a white plastic-like coating and is used for shelving because I had some laying around, and because I didn't want to have to account for leak-down pressure loss through the particle board. I'm sure coating or painting plain particle board would be fine too. I also used contact cement between the wood cap surface and the cylinder ports -- I'm pretty sure I left the gaskets off. I then cut off the air fill nipple from an old bicycle innertube, and pressed it into a tight hole drilled into one of the aforementioned particle board port caps, with some contact or rubber cement to secure it air tight. OK, with this I can attach an air hose to pressurize the engine -- but don't stop reading now or you risk *creating* a big problem instead of solving a little one. You will also have to block off the exhaust port. However, you don't want to do this at the manifold to cylinder ports because you must assume that is the source of air leak. (In fact, I think that is the most likely leak area, and is where I found mine. Fortunately it is also a no-brainer to fix.) I took off the exhaust can and rigged a wood plug with gasket sealer for the exh manifold at the end of the Y. Here's the most important part: You want to be sure to pressurize the crankcase at no more than 4.5 or 5 psi or you risk blowing out a seal -- I don't know what pressure will guarantee damage -- anyone who finds out probably won't want to 'fess up. :) A compressor regulator gauge (0-120psi) is not accurate enf for the low end (4.5 might really be 10, especially when reading pressure from a very small vessel). To work around this, I tweaked the regulator pressure to the point where air would no longer flow into my tundra tires when a known good tire pressure gauge measured them at 4.5psi. Then I shut off the compressor and felt free to pressurize my engine. The leak areas you are looking for (i think) include exh manifold, head gaskets, cylinder to case gaskets, PTO seal, front seal, and internal crankcase cyl-cyl seal. I had taken off my gearbox to check for PTO leakage, but I would not mess with that or the other crankcase seals unless you find no leaks on the easier to check areas. So, pressurize the the bike tube nozzle and use a spray bottle with soapy water on all the possible leak areas. On mine, the exhaust manifold areas fizzed like a rabid dog and all other available areas were fine -- what a relief! If you are not finding leaks on the outside of the engine, you need to assess whether the leak-down rate (amount of pressure lost with time) exceeds spec. I think that too much leak implies that the internal cyl-cyl seal may be bad, especially if soap bubbles show no leaks on the PTO or front of the engine. I forget where to find teh leak-down rate tolerence. Here's an interesting kicker. All of my problems started after doing some maintenance, I think it was decarboning at ~120hours. Not wanting to cut any corners, I had put the manifolds back on with brand new gaskets. Still, within 10 hours my Firestar was not much more than a powered glider. Henceforth I have used gasket sealer when bolting on the exhaust manifold. If that is as likely a culprit as I think it is, you could possibly avoid the entire test above, and instead simply rebolt the exh manifold on with gasket sealer and see if the problem goes away. I'd bet a nickel that every engine out there would run with more reliable mixture if sealer was used on the exh manifold, but now this is turning into religion, so I'll quit while I'm ahead. -Ben Ransom =====

Subject: Re: Interest in Leak Down Test
Several years ago I had an aircraft with a 532 that leaked between the cylinders in the crankshaft area. The 532 and 582 have an oil chamber there, as that is the area where the oil pump/rotary valve shaft gears off the crank. Everything was normal below 5,000 RPM, but at higher throttle settings, the leak in pressure caused the little oil bottle that contains the crankcase oil to suddenly overfill and spray oil everywhere. A pressure test verified the between cylinders leak. A previous owner had worked on the engine and reassembled the crankcases with RTV. (ARRGGHH!) You have to use the sealant specified by Rotax, or it will leak.

Thanks Erich. I think that photo share feature is a great option for us. Regarding the post I sent a week or 2 ago about changing the location of the wing fold bracket; today a friend (the gyrocopter builder) and I started work on the crossbar to hold the bracket, when he came up with an idea: why not locate everything as shown in the plans, then make a bracket - like with a piece of 4130 tubing, as long as necessary, say 12" or so - with a short 90 bent into each end. Like an "S" or "Z" shape. Slip one end over the stub on the fuselage tube and pin it, then slip the wing spar stub into the other end, and pin it. This would hold the wing higher off the ground, and would be simple to make whatever length you need. That, combined with the strap between the 2 wingtips should hold everything plenty rigid. We're gonna build it this weekend, and try it out. Larry Bourne Palm Springs, Ca.

Should I keep mine on (it goes all the way up, but not all the way to the sides) or should I cut it back to a 1/2 shield or should I do away with it alltogether.

Keith Singer Keith and Gang: I flew my Ultrastar with no windshield, but required goggles or full face helmet with face shield, so I could see while wearing glasses. On long cross country flights, sitting out in the windstream was fatiguing, hold head against the blast. My Firestar, initially, had the same problem, since my head was still in the blast with the half windshield. Still had to wear goggles over my glasses so I could see. A small lexan fairing on top of the half windshield kicked the blast over my head, allowing me to fly with baseball cap and glasses. The Mark III is fully inclosed. No longer required to fly sitting in a hurricane. I prefer the inclosed cockpit now. Have flown many hours in this configuration. The way each individual flies is a personal thing. If you are like me, you will have to experiment to determine what configuration you want to fly. All it cost is time and a little lexan. BTW: I am in Roanoke, VA. Been here since last Thu. Arrived in a snow storm, pulling the 5th wheel. Had planned on heading north up I-81 to visit with the Gray Baron (Bob Noyer) in Winchester, VA, but as of last night the weather was no good in his area. Will have to play it by ear and keep up with current weather between here and Winchester. If it doesn't clear up, will have to return to hauck's holler, alabama, Thu.

Take it off and try it. Find an old piece of Lexan that is not good enough for keepers and make a half windshield and see how you like it. If it suits you, use it for a pattern for your final product. I have a MKIII with a half windshield, and it flys better. I love the visibility and openness.

> What's the prevailing wisdom on the windshield vs. no windshield issue. Ive found that the windshield on any UL does limit visibility somewhat, but he alternative is a full face helmet which limits visibility even more. When I bought my Phantom 3 years ago it had a very low windshield on it. I was always getting hit with jumbo sized bugs. I even had a bird strike once. A bird went through the prop and sprayed liquid bird all over me and the plane. I was wearing goggles but a small piece of bird still got past the goggles and in my eye. After that I built a full coverage, wrap around windshield. The other nice feature of a windshield is that you can fly alot longer with a windshield than without. Guys that fly open air UL's are usually good for a little over an hour. Guys with enclosed UL's can easily do three times that. Im working on the full enclosure for my Twinstar now.

Subject: Re: Short Windshield
> >Fellow Kolb Pilots: > >What's the prevailing wisdom on the windshield vs. no windshield issue. Keith, I fly with a short windshield and my head sticking out in the air stream. I flew with a full face covered motor cycle helmet, but it was very confining, the drag profile was too large, and vision was limited. Currently, I wear a soft flying helmet with goggles over glasses to keep my head drag profile to a minimum. It is comfortable up to about 60 mph. If I want to push on up in speed, I slouch down and forward to reduce my drag profile. I have experienced some neck muscle soreness in the past, but not lately. Most of my cross country flight legs are about an hour in duration due to fuel limitations. The importance of goggles should not be ignored. Since I wear glasses, I thought I could get by without goggles, but on take off one summer evening I found out otherwise. My take off roll was through a cloud of nats. One hit the bottom edge of my glasses and it stuck there except for one wing. It came up under my glasses and into my eye. Just as I flew off I had this pain in my left eye and tears came up in both eyes. It was interesting for several seconds, trying not to blink because it hurt to and having to blink so that I could see. At about 200 feet above ground, my vision cleared and I was ok. Since then I always fly with goggles. I have not tried it yet on the FireFly but I believe if one could significantly reduce head drag by covering the cross space from the wing attachment beam that is over head and down on the almost vertical cage members to the level of your shoulders. This would put your head in stagnant air bubble and reduce the force one would experience on their neck. I fly all year around. If it gets below 50, I start to wear a neck sock with the soft helmet. If it gets below 40, I wear head and neck sock beneath the soft helmet plus what ever else it takes to keep me warm. Some photos can be seen at: http://www.thirdshift.com/jack/firefly/firefly14.html and the following two htmls. I encourage you to try flying with no or a short windshield. The view is just fantastic.

Date: Jan 07, 2002
Just received revised plans for the horizontal stabilizer for the M-III Xtra. Curious if this stab design is from the original M-III or a new design. The revised plans use 7/8" x .049" tubing for the inboard and rear of the stab and 1" x .035 tubing for the leading edge. Also, the leading edge meets the trailing edge at the outboard end to form a triangle. The original stab design used 1" x .058" tube all around the perimeter and the leading edge is separated from the trailing edge by 12" at the outboard edge. Doe's this revised H-stab sound like the original M-III stabilizer? Also curious if any Xtra builders out there also received similar revised H-Stab plans. I plan on using the original large stab as I have already built them. Can't think of any reason for the change except to save weight.

Keith, You might take a look at my long windshield which is the best of both worlds. I'm out of the airstream but I can peak around it if I have to. Full enclosures are too hot in the summer and can fog up without adequate ventilation. I was flying a Mark II once with a friend when we ran into freezing rain. It became difficult to see out and we were lucky to be within a few miles of the field. If I were flying my Firestar, I could have leaned over to one side to see ahead. I know of one Titan pilot who took off at Sun-N-Fun with a fogged windshield. He knew it would clear up on climbout, but until it did he was flying blind. Take a look at my pics to see the long windshield. http://www.matronics.com/photoshare/ul15rhb@juno.com.12.10.2001/ Ralph Burlingame Original Firestar > > Fellow Kolb Pilots: > > What's the prevailing wisdom on the windshield vs. no windshield > issue.

Craig, My uncle and myself are building serial number 10 Extra. We went to Oshkosh for the first time last July and couldn't wait to see all the folks and planes at the Kolb tent. We were both a little disappointed to find out that they had sold the original Extra and had the new version which they are currently sale now. Their Firestar did not have the updated control system, and the Kolbra was not the one I had always seen in all the magazines up to that point (you know the all red one with the shark nose design like the Extra). Anyhow, when we were looking at the Extra for a few minutes we finally turned to each other and said this is a Mark III with a different nose on it. Gone was the original dual stick configuration, the center between the seats is simpler, the shape from the cockpit to the tail tube is back to Mark III shape with no ring around the tail tube exit, as well as the shape of the horizontal stabs went back to Mark III, etc....... After talking to Danny M. he said that they were trying to get the weight down on the Extra, and this is what took out a lot of extra shapes and welds out of the plane. They really wanted to have a good two seater that can carry a load for training under the new sport aircraft proposition. I do have to admit that I am concerned for the final weight of our Extra, but glad that we are fortunate to have one of the original Extra kits before their change. I think only about two dozen kits of the original design are out there.

01/08/2002 12:20:15 PM Big Lar et al: Read your List post - not sure we are on the same wavelength here - I know thats how it goes with the list sometimes. With respect to my saddle - it DOES get you clearance between the leading edges of the folded wings and the ground - that was the main purpose of it. The longer you make the extension (the 2-inch diameter PVC nipple) on it and/or the bigger your wheel, the more clearance you have. Know what I mean? The clearance is also affected by the position of the saddle on the fuselage. Closer to the front end lifts the tail higher. On your wing bracket : Im not worried about the wing not being held securely - I was commenting on the possibility of the bracket itself rotating slightly on the wing holder - its got to be in just the right place for the wing peg to fit into it, right? Hope Im not pissing you off here - certainly not my intent! Just trying to clarify my thoughts. I think your bracket is a worthy pursuit. Whats the status of Vamoose - is she getting covered? regards, Erich Weaver erich_weaver(at)urscorp.com 130 Robin Hill Road, Suite 100 Santa Barbara, California 93117 Tel: 805-964-6010 fax: 805-964 0259 I like your saddle arrangement, Erich. The bigger wheel you mentioned would make it even better. I think that, combined with a way to get the leading edges higher off the ground would be a win-win combination. Rotation of my bracket shouldn't be a problem, since the rear universal joint will keep the wing from moving fore and aft. Who was it that published the pic of the strap holding the wingtips together ?? Could you publish that again, please ??

"Just received revised plans for the horizontal stabilizer for the M-III Xtra. Curious if this stab design is from the original M-III..............." The version with the 7/8" and 1" tubes and the triangle on the O.B. end is the design for the original Mark III. When I changed to the Mark III Xtra the stab. was changed to the 1" tube all around and the 12" "extension". This was because Barnaby thought extra area was needed because of the wider front cage. I noticed at Oshkosh this summer that the new "lightweight" Mark III Xtra went back to the old design smaller stabilizer. (I guess the extra area wasn't needed and they wanted to save weight.) Any comments on this from anyone?? I am also going to keep the larger stabilizer since I have not heard otherwise from the factory. Note that the position of the L.E. has been changed to near the center line of the tube rather than at the top.

It would very likely save one neck. The vertical bar on a friend FlightStar saved his neck, no doubt about it. Keep the bow and the windscreen. jerryb > >I vote for keeping the windshield.

[Sorry about that last message (with the "StripMime Report" error message). That's a new one to me! Here's the message I was sending...] Just thought I'd mention another "windshield" option: a full-face helmet. With a clean visor, it's as though there is *nothing* in front of you. (Especially in an UltraStar!) Winshields collect bugs, grime and scratches, and are expensive and somewhat difficult to replace. Replacing a helmet visor is trivial. The only problem I have with the full-face option is that without any enclosure at all, there really is a little too much wind coming in under the chin. In my motorcycle riding days, this was not a problem at all because I was leaning forward; in my UltraStar, I'm rather reclined (due to long legs and seat position required for CG), so the wind is coming up more from below. I've considered adding an extension to the chin guard. I must say, however, that a bracing tube on top (or a pair of them) sounds like a very good idea, both for safety and for structural efficiency. For me, the only reasons to add a windscreen (in addition to bracing tubes) would be to be warmer in the winter, or to improve aerodynamics. -Mike Ransom >--- VIC wrote: > > > > I vote for keeping the windshield.

Mike, You brought up a good point. I think your on right target about leaning forward versus reclining position.

Subject: FireStar Controls
I have posted about this problem a few times in the past and have gotten very few responses. An FAA inspector checked my plane out today at my request. I had tried to discuss this with Kolb but had very little satisfaction going in this direction. It is my understanding that Kolb can design there control system any way they want to but we as builders have to follow their design or be in violation of regs. I felt the Kolb's system was flawed and tried to work through Kolb but had no success. I live only about 4 hours by car from London Ky and was willing to drive out there but could not get anyone interested. I had two choices. Build the FireStar to Kolb's design or modify it to what I thought was a safe design and run the risk of not being able to get the plane approved. Neither of these was an acceptable option to me, so I decided to see if I could get the inspector to grant me permission to go with my modified design. As I said, he was here today and he agreed with me 100%. The Kolb design is flawed. He took numerous pictures and will file a report with the FAA in Oklahoma City as well as the EAA. He then told me to build my plane using my design and not to use Kolb's. He also asked that I take all measurement of my system that I could so my system could be applied to other FireStars. I am posting this to make everyone with a FireStar aware that there could be a potential problem. I hope Kolb does not get mad at me as I feel I am doing them a service. Should someone get hurt or killed and it is determined that the problem was with a flawed system that they knew about, that release we signed would not be worth the paper it is written on in a court of law. As I said, I had posted about what I thought was a problem and now has been confirmed as problem, a few times in the past. I will not post anything more about this.

Ron, I'm not a DAR but I been around some good builder orientated technical counselors of which one is a DAR. Unless something has changed recently I know of no regulation you violate making any change you want during the construction prior to the final inspection and issuance of the airworthy certificate. Your the manufacturer, its your responsibility to see aircraft is safe. And as the manufacturer (you) hold that liability. The FAA or DAR inspector is responsible to see that the proper paper work is in order and completed, it has proper labels, and that proper aircraft construction methods have been used. They will not guarantee that the thing will fly nor that it will not fall out of the sky. The DAR's will often look it over closer than an FAA inspector more for liability protection reasons. Think about it, you can build your own design, or a plans scratch built, or a prefab kit meeting the 51% rule for amateur built experimental. Nothing stops you from making design changes prior to the final inspection. Once the final inspection has been completed, the test hours flown off, and the airworthiness certificate issued, you can not make any changes or modifications that may impact flight performance such prop, engine, flight control systems or flight surfaces.

The nicos at the rear end of the rudder control cables rub slightly, on the elevator control mech, in the up position. Adjusting the rudder horn upwards solves that problem, but forces the nicos into the boom . Drilling a 3/16" hole on both sides of the rudder horn a 1/2" from the original holes and connecting the cable there solved that dangerous fault.

Any major deviation from original design as approved by the FAA in granting an airworthiness certificate, must be approved by the local Flight Standards District Office. If you have no "N" numbers then the fed just wants you to be safe regardless of who designed the craft.

What regs would you be in violation of? Its an experimental aircraft. As the builder you can build or modify anything you want. If Kolb ever comes out with a cerified Firestar, then you would have a problem modifying the design. On a certified airplane, The feds certify it as the factory builds it and you can not modify it. There are no laws that say you have to adhere to the plans. In all my years of building planes, Ive never had an FAA guy even look at the plans. All they are concerned with is whether the plane is airworthy, which has nothing to do with whether you deviated from the plans or not.

In a message dated 1/12/02 11:45:13 AM Eastern Standard Time, ronormar(at)apex.net writes: Ron: Your post raises some interesting questions about the control the FAA has over kit aircraft manufacturers and the degree to which they can approve or disapprove design work done by a kit manufacturer. Frankly, I think your post contains a number of misconceptions about the regulatory environment folks like Kolb operate in, so let me try to straighten you out. "It is my understanding that Kolb can design there control system any way they want but we as builders have to follow their design or be in violation of regs." Of course Kolb can design the control system any way they want. So can Cessna and Piper. Over the years aircraft manufacturers have attempted to put some real crap on the market. The original Cessna Cardinal tail, and the T tail in the Piper lance come immediately to mind. The difference between Kolb and a GA manufacturer is that the GA manufacturer's design is required to meet certain performance requirements and if they don't comply they don't get to sell that plane to the public, and if we discover a problem later we can fix it through the Airworthiness Directive process. There is no such restraint on experimental kit manufacturers. Keep in mind that many of the early kits had no control systems at all and simply used weight shift. The FAA's position, at that time, was that you were welcome to try to kill yourself in anything you liked as long as it weighed less than 254 pounds empty. Back when those regs were promulgated no one in the FAA ever dreamed that the experiemtnal/ultralight movement would be so successful, so they just turned their back on it. Now, nearly 30 years later, the magnitude of their error is evident-- a whole generation of fat ultralight and experimental pilots have come up thumbing their noses at the FAA and completely ignoring them-- and now threaten to overwhelm GA, leaving a huge segment of the aviation business basically unregulated. Your notion that you are required to build what Kolb designs is just plain wrong. On the whole I think its a good idea to follow the plans, and wild deviation from the plans might draw some extra scrutiny from your DAR or MIDO inspector, but there is no regulation you can contravene by deviating, because the FAA never approved the design or its performance in the first place. The late Jim Lee used to buy Kolb kits and so radically make them over in the course of making his amphibians that no reasonable person could call them a Kolb product. Whenever one of Jim's customers would kill themselves, and indeed when Jim bought the farm himself, it was necessary for Kolb Aircraft to make that point on the record, but it didn't stop the FAA from issuing Airworthiness Certificates to Jim's customers. "I felt the Kolb's system was flawed and tried to work through Kolb but had no success." Sounds like you have a difference of opinion with the folks in London. But because there is no certification standard that's all it is. A difference of opinion. Your idea might be overwhelmingly superior-- but when you are talking about experimental aircraft we all still get to pick how we want to jeopardize our lives and property. You may think your way is better but there is no way you can impose it on everyone else. "I decided to see if I could get the inspector to grant me permission to go with my modified design." You didn't need to ask. The simple fact of the matter is that the Kolb plans are quite vague in a number of particulars and all of us finish these aircraft more or less to suit our own taste. "As I said, he was here today and he agreed with me 100%. The Kolb design is flawed." Once again-- his opinion. Even if he thinks the control system is horribly dangerous there is nothing he can do. "He took numerous pictures and will file a report with the FAA in Oklahoma City as well as the EAA. He then told me to build my plane using my design and not to use Kolb's. He also asked that I take all measurement of my system that I could so my system could be applied to other FireStars." Naturally, I'd love to see a copy of that report, as I'm sure most Kolb owners would, and hope you will pass it along or post it when it becomes available. But keep in mind there is no way that I know of to impose your design on other Firestar owners who are happy with the system as supplied by Kolb. There is nothing like an Airworthiness Directive system for experimental aircraft which would render a Firestar unairworthy if the owner didn't comply. "I am posting this to make everyone with a FireStar aware that there could be a potential problem. I hope Kolb does not get mad at me as I feel I am doing them a service. Should someone get hurt or killed and it is determined that the problem was with a flawed system that they knew about, that release we signed would not be worth the paper it is written on in a court of law." I'm sure the Kolb company is grateful for your opinion. Its a funny world we operators of experimental aircraft live in-- none of us wants the expense or hassle of being regulated by the FAA, and would rather be ignored by them. But you can't have it both ways-- if the FAA doesn't regulate us the lawyers and the court system will. Take your pick. Mark R.

As far as I know, and one could ask Kolb, none of the Kolb designs have been certificated. The process is too expensive. I bought a kit, that included a sketchy Builders Manual and a set of drawings that did not include any statement by the FAA that this was a certified design. I do not believe the Feds care whether I change my flight controls or not. And just because an "experimental" design comes from Kolb or anyone else does not mean that that most designs cannot be improved upon. Each of us has to evaluate what it was that we purchased from Kolb, decide if we can make it lighter, better, safer, and if one is comfortable, to go ahead with the change and log it in your manual. Originally, my FireFly was a very unpleasant plane to fly, and now it is a pure joy. This has come about by slow incremental change. Remember "Experimental" is what it is all about. Jack B.

Subject: Rotax 447 & Bing Enrichment Valve Spring
Just a note. I have had trouble with my 447 loading up at low engine speeds, such as, taxiing out to the runway or holding for another plane to land or take off. Since I have only taxiing brakes, I can not effectively run the engine up except on the take off roll. Several times it has taken almost 600 feet to get it to unload and for the engine to spool up. By accident, I have found the cause. I put a fuel flow meter on the FireFly to try and figure out how to get better fuel economy on cross countries. This week as I was taxiing out to the runway, I noticed that the fuel flow was higher with the throttle almost closed as compared to the 3000 to 4000 rpm range. I thought about it some, and I realized that if the fuel enrichment valve spring was too weak, the high vacuum in the intake manifold at closed throttle could lift the valve off the seat. Since I am getting a Victor 1 ready to mount on the FireFly and this engine uses the same carburetor, I removed the enrichment valve spring and took it with me to the airport. I compared this spring with the one on the 447. Sure enough, the spring on the 447 was a much lighter spring. I checked the Rotax site for updates, and I found nothing that mentioned this spring had been changed. So if you have an older 447, mine is four years old, and if your engine is loading up on you when it is running at idle or low speeds, you may want to purchase a new Bing enrichment valve spring. It could make an important difference on a short or soft field take off. Jack B.

Unless you tell the FAA guy that you changed anything, how's he gonna know? They don't care about that kind of stuff. Most will give the weight and balance form a very careful scrutiny, and the good ones will look for acceptable methods and practices and look for obvious screw ups, but it is not their job to see if you built it to plans. Unless they have a skewed concept of their legal responsibilities, they don't get involved in that end of it. As far as plans goes: you don't even need plans, if you built it all off a sketch on a paper napkin, who cares?

Major deviations or major changes require an amended airworthiness certificate. But that comes after the granting of the initial airworthiness certificate, not on the initial inspection that gets you the certificate in the first place. And you do not have to ask before you make the change, because you are still the manufacturer, and you can change it any way you want. But any major changes require notification. When I cut down my windshield three years ago to modify the airflow around the center section of the wing, that was considered a major change.

I am also building a updated Firestar II kit, and after seeing what Ron has modified and why he modified it makes me really think of applying what he has learned. Kolbs current demo Firestar still has the old control system. Why are they not flying the new system in their Firestar? It should be a great selling point, cleaner and simple control design?

As I stated in an earlier post, I have not read the regs. I only know what a DAR told me. Wether I was informed right or wrongly has no bearing on the control cable problem. I felt there was a potentially dangerous problem and the inspector agreed. If I had made a major modifacation to the system without the inspector's blessing, then it would be up to the DAR at the final inspection to approve or disapprove of what I had done.

Not because of the bad weather we have, but, more because I can't always get to a place to RENT an ultralight. I've owned every version of flight sim that I've ever seen on the shelf.! If you want realism, try the newest one from MS .... Flt Sim 2002 Pro.

Also, if you look around at some of the Flt Sim web sites, you will find many different types of aircraft designed for use in most versions of this and other flt sims.

I read the manuals ( rather thin on details ) the large one dated June 2000 has the aileron and Flaps section X'd out has this been replaced? Has anyone been issued any updated changed to the manuals yet ( I will be e-mailing Kolb on this ) What tools did you think helped the project. ( I have a pneumatic riveter) In the Manuel is say to prep and paint all steel parts. Did anyone have any problems fitting painted parts? I'm near Reading Pa. so if anyone is close I would like to see a Pre covered MkIII or xtra. Thanks Ken ________________________________________________________________________________

I have a 14 inch bandsaw, put on a bi-metal blade and cut all my pieces with it. Cut the tubes, the gussets, etc., but when I was done my pieces looked like they were factory made. I even built a jig to hold the spar tubes and cut them on the bandsaw. The large bandsaw enabled me to open the throat wide enough to get the spar into the saw. I also have a machine belt sander (not a handheld) that I used to dress up all the cut edges, another piece I would not have done without. A good cordless drill and If I did it again I would get a pneumatic riveter. I also built all my ailerons, elevators, etc., with 90 degree bends in the tubes and my trailing edges have a 90degree bends at the ends. (the most difficult option for building on the plans) anyway, in building I made a lot of jigs to do things correct, the jigs took a lot of time to design and build, but I would be glad to share the ideas with you. I am in NVirginia, I would be glad to show you what I have if you want to take the trek. Tim ________________________________________________________________________________

01/14/2002 11:11:01 AM Hey Mark, when we share ideas for deviations and improvements to the Kolb designs, are we opening ourselves to liability? Specifically, I was thinking about Ron's new improved control linkage, a deviation from plans, and his sharing it with others on the list. It is his design, not Kolbs, so in the event of a crash of a plane with his designed control on it, could someone find him partially responsible? I'm not try to stir up trouble, but this seems to be bordering on a Jim Lee situation, and we are treading away from Kolb factory support.

I have resumed work on my Mk3 Classic/912. My main hang up was with where to mount a panel for the Ign, Master, EMS switches. I wanted to be able to reach the switches from either seat without unhitching my seat belt. The instrument panel is a full 12' out of my reach and it's already full. The Kunzelman answer is to build a small panel just in front of the left seat but the dual controls in my machine made that impossible. After thinking about it for a while I designed and built a short pedestal which is located just ahead of the cross tube of the dual controls. The rudder cables pass just above it and it is far enough forward to be clear of the elevator control arm on the control cross-tube. I can reach it from either seat and is sloped so that the switches are always visible. The pedestal wiring is now complete and I am working on the Hotbox. The engine interface wiring will be next then on to the fuel lines.

Hello Kolb builders: Names Don Martin (Seattle, WA). Been building a Firestar II for about a year now. Found your help on the list invaluable. Tried to live by the rule to measure twice and cut once and so far all has gone well. Ive completed all the major structures, but left the ailerons for last. Two days ago, I started on the right aileron and thought I had it down right. Then in preparing for the hinges I found out that I blew it. I made the inboard end of the aileron too long, went one rib too close to the steel inboard rib. weaken the inboard edge. Can I leave it as it is? What would it affect? I originally thought just keep it, and it should give me more aileron control. Theres still about 39 inches to the inboard rib, so the prop clearance should be OK. What could go wrong? Would that extra change the stall tendencies of the inner portion of the wing? Keep it as it is? But when Homer designed the aileron, there must have been some reason why he measured it to the 4th rib rather than the 3rs. Suggestions?

Ken, It is the Kolb way to butt the tubes to each other and to attach and reinforce the area with the gusset. If you can do a saddle cut, you will have a slightly stronger joint as well as aesthetically better looking joint. But, once covered you won't see your handy work any longer. It's your call, if you want to take the time to make saddle joints, do it. Or, if you wind up doing the butt joint, that is permissible as well as plenty strong.

Subject: 1 or 2 place...
From: Richard Carlisle <rrcarl(at)concentric.net>
I need opinions. Ive taken my Twinstar apart down to every last rivet and thrown the parts in a big pile. The wings and tail tube are OK. The rest needs to be scrapped. Ive already started building the new plane from these parts. Question is...Should I make it a 2 place or a single place. Im adding some creature comforts like a full enclosure, electric flaperons and electric trim. The plane will also be equiped with about 10 lbs of camera and video gear. Im pretty good at coming up with light weight parts. For instance, the 12V flaperon acuator only weighs 1.3 lbs and the trim servo weighs 4 oz. I am building the pilot/pax compartment from 100% advanced composites...No steel. The layup will consist of 4 or 5 layers of S-Glass with a nomex honeycomb core. The whole thing will be vacuum bagged in the mold. The reason for going composite was that most of the 4130 forward of the gear was junk...Rusted from the inside out. I am about to start building the mold, which is why I need to decide which way to go. What do y'all think? If I go single place, it would pass as a fat UL and I could get by flying it in the UL catagory. It shouldnt weigh much more than my Phantom. This whould make a real nice single plave rig that could carry loads of baggage, extra fuel, cameras, etc. If I go 2 place I would definitely have to register as experimental. A big pain in the butt. I could carry a pax, but not a heavy one. I average about 250. The older Twinstars have about 400lbs payload...Pilot, pax and fuel. me (250) and fuel(60lbs) leaves 90lbs for a pax. Not much good in my opinion. I figure pushing it, I could carry a 150lb pax. Considering the max payload, pilot weight and FAA complications, how would you go. Please place your vote and make an argument to support it. I need to justify which ever way I go. Thanks...Ross ________________________________________________________________________________

Here's my 3 cents - With its limited (marginal) payload I would say keep it a single place. Reduces your liability not carrying passengers plus it eliminates the issues with conventional inspections each year. Make it so you can carry some extras for making a moderate x-country. jerryb > >I need opinions. Ive taken my Twinstar apart down to every last rivet and >thrown the parts in a big pile.

You'll discover that you don't REALLY need many specialized tools to make one of Homer's airplanes. Many List builders have used pnematic riveters, band saws, drill presses, grinders, and other convenient power tools, but they aren't a requirement to build the airplane. I have proven to myself that a Kolb can be built without all those. You will need a drill, of course. And a vice, too. But I did all my metal cutting (tubes, sheet alum) with a hacksaw and tin snips, and used files to smooth the edges. Did all my riveting with a hand-riveter. ( I have a very firm handshake, now!) And I believe my airplane turned out just fine. (We'll see what the FAA inspector thinks, when he comes out to perform the final airworthiness inspection next month!) As for specialized tools, you'll want a set-punch (spring-loaded punch, for making dimples for drilling) and a cleco set (the cleco pliers and a couple dozen cleco fasteners). You'll also need a tool for swaging cable ends. I borrowed one from a fellow homebuilder in my EAA chapter. But the best tool you'll find during your build process is this List. (Was for me, anyway!)

Subject: New Mk III Xtra Kit I owner - Tools
Ken, Regarding the spring loaded snap center punch, don't waste your hard earned money on one of the cheap knock offs, buy the General Tool one. It will get used a lot. It will cost around $15-20 bucks depending where you get it. If you should happen to drop it and break off the replaceable tip, it can be repaired - there is a way to extract the remainder of the tip. Repeat after me, "I will never use a pencil to mark my aluminum parts unless I want to die." It is an established fact in the aircraft industry that pencil lines on aluminum may develop cracks Get some fine felt tip permanent markers - Pilot or my preferred but harder to find the wonderful Stabilo - OHPen96P fine tip but harder to get - carried by larger art & graphics supply stores). Note the extra fine tip will not hold up well but are good for fine detail. Forget Sharpies, they don't last, a couple lines on new aluminum and they quit writing, been there done that. A flat and round rat tail file - medium ~8" & small 4-6", a small half moon comes in handy - you can often buy a imported 4-6 small file kit for $5-$7. Deburring tool - this is a tool that has a small joggle blade extending out of the handle and is used to debur holes. A handy tool is the Delta 1" wide belt sander. They also make a model with both the 1" and a 5 or 6" disc. This is a very handy piece of equipment. As for rivet pullers, get a good US made one, will cost around $20-25 last time I knew. The difference of the cheap one show up after they wear - don't grab, don't release the stud, or worst breaks them off - Harbor Freight sells a neat puller that allows you to rotate the head you can get access at different angles. Some people like the bullet tip drill bits but I myself don't. To me they always act like there dull and you can't resharpen them. Sharp drill make the job much easier - if you by them from machine tool supply like ENCO Tools - there less expensive and you can change them often. Try to get the US made, there better - the China drills can be brittle some times. I gotten good ones and I gotten one bad lot. Buy them by the 10-12 to the pack. Avery below also sells long drills should you need one 1/8" 6" & 12" - I've also recently seen them in Lowes Building Centers marked down for clearance. Some 1/8" Cleco's are nice to have for temporary assembly. - See Avery below Some good tin snips - 15" or so - example Andy=99 aluminum combination snips 14" sold by the outfit below. - See if they have them locally but if not Avery has them - I just recently seen them for $25 in hardware store. The longer handles give you leverage and makes cutting easier. You can find many aircraft tools at Avery Tools. These are good people - support Van RV builders - but for some things you need to shop. http://coldfusion.averytools.com/ A Step Drill is a handy device for drilling larger holes >1/4 up to 7/8 or 1" - little pricey but sweet. They make 3 different sizes - A good 6" and maybe a 12" metal scale - they come with different models with different dimension markings - I like the 64th & 100th which is common or 32nd/50th. I have one that nice if your staying to fractions, it has 1/8, 1/16/. Some manufacturers are easier to read than others. Its more personal preference. When you get to the covering phase, get a jar of the hand protection cream that Rutan uses, Series 8 sold by Aircraft Spruce P/N 13-38306. The 4oz. doesn't got to far so I would get the 32 oz. jar. ~ 4oz/$5 - 32oz/$15. It helps to seal and protect your hands from the chemicals and makes it easy to clean up.. A good flat table to build you surfaces on - make it out of 2x4 and a solid core hard board covered door (Home Depot or Lowes) - The table needs to be level it or you will build twist into your flying surfaces, not too desirable. Saw Horses - I like the folding metal ones that top is 2x4 and legs are metal - they come knocked down and you have to assemble them but there nice. About $20 per pair. Sold on and off my Home Depot and Harbor Freight. When you get to setting up the control surfaces to valid deflection, you may want a gravity type protractor angle gauge. Start salting some money away for levels - when you get to setting up the wings for mounting, you need a couple levels - read a head on your planes and see what you will need. One of our locals put a metal blade on his table saw and cut his tubing on it. It worked good, produced nice clean cuts. If you don't like cutting with a hack saw you can get a horizontal/vertical power band saw for $150-200. He made templates for all his gussets - would draw the outline on the material cut as well as possible and them sand it on the belt sander. Wear a dust filter mask so you don't breath in the aluminum dust. Got any money left, I'll think of more. jerryb > > >On 1/14/02, KDJames(at)berkscareer.com wrote: > >< What tools did you think helped the project.

Hey don't forget that we will likely have a sport pilot program in place before you will be able to finish that airplane. At that point the registration process for that airplane should be the same thing for both the 1 or 2 place airplane. If you already have a 2 place airplane then by all means build a single place airplane. You do pay a performance penalty for carrying that extra seat along. If you are like most of us and only have one airplane then it is real nice to have a 2 place airplane. It is very important to me to be able to share the fun of flying with other people.

Ken, I use Sears Craftsman tools because they will give you a new one when the old one breaks or is worn out. I've used more than half dozen stem rivet pullers on Cherry-Max rivets, and the puller lasts abt 2-300 rivets--then it gets turned in. Same for sockets, etc. But they only install a rebuild kit in the ratchet wrenches now. A cheap tool is OK for a few times' use, but breaks when you need it. I get a load of static when I take back 50+ yr old tools--the orig dull cad plating has gone, so Sears says it ain't theirs because it isn't bright chrome---but still has Craftsman on it. Like to see them squirm! bn the old one ________________________________________________________________________________

From what he indicated, it sounded like his remaining payload would be very limited (marginal). Could get him into trouble. He estimated his finished weight and they always weigh more than you thought they would meaning that payload would be less. He can build it and document the building process - journal and photos and register it later if he wants. jerryb > >Hey don't forget that we will likely have a sport pilot program in place >before you will be able to finish that airplane.

Subject: Tools
I would rather keep the old tool, better than what their selling today. I have some Sear tools also but they keep reducing their selection. Pretty soon I will not have nay reason to go into their store at all (is there a message here). My problem with Sears is they keep eliminating their selection of 6 point sockets and selling mostly 12 point. Reason people torque the 6 points or use them on impact guns and crack them. 12 points are not good unless your working only on new or nearly perfect bolts and nuts, if there rusted they round off the bolt or nut then you got a problem unless you got some good 6 points. The 6 point has more gripping surface thus less chance of rounding off rusted bolts or nuts. I got into using a SK Wayne 3/8" drive socket set while working in an auto center putting myself through school. That was back in 71 - I still use that set today 30 years later. Great tools but getting harder to find at a fair price. The last place i found to buy the SK 3/8" drive sets at a good price was Harbor Freight. Unfortunately SK has cheapened up the nice box they used to come with and reduced the contents some. You can buy individual pieces to add to the set but its too bad, they had an excellent starter kit.

I just posted what is accepted as a no-no in the aircraft building industry, do not use pencil to mark on aluminum in an aircraft. Use felt tipped pens. You little inspection only proves you can not detect any cracks today but why encourage people to do things their being wared not to for good reason. Myself if I were doing a pre-buy inspection on you plane and found pencil has been used to mark aluminum components, I would walk away from it. This is not a hoax. Some years back the wings were coming off B-52's. They finely were able to trace it back to the manufacturing process where some one was using pencil to mark lines on the spars. It was found that cracks developed along pencil mark lines. Your plane may not ever have a problem but its been established its bad to use a pencil on aluminum in an aircraft. Now that your aware of it, don't do it. jerryb > > > > >Repeat after me, "I will never use a pencil to mark my aluminum parts > >unless I want to die." > >It is an established fact in the aircraft industry that pencil lines on > >aluminum may develop cracks t. > > It may be an established fact but last year I had the opportunity to >disassemble a Mk111 that was about 10 years old.

We got some very good Technical Counselors in our local EAA chapter including A&P's and a couple DARs. The chapters experience and knowledge base is probably much higher than most as we have a large number of builders especially of the Van's RV metal aircraft, including myself. If your were caught using a pencil while laying out aluminum parts they would have you flogged. This is not made up or make believe. No matter how you try to justify it, in the aircraft industry it still remains a no-no, plain and simple. Just because so far you've gotten away with it doesn't alter that fact. All I can do is try to lead inexperienced builders in the correct direction by alerting them to the proper methods and practices. If you want to use pencil on your aircraft that's fine, I can't stop you but later if you came to sell it and I were to do a pre-sale inspection and discovered you had, I would walk away from it. Sorry, no sale. jerryb > > > > It may be an established fact but last year I had the opportunity to > > disassemble a Mk111 that was about 10 years old.

Stop trying to justify it and just accept that laying out aluminum parts with pencil is not an accepted practice in the aircraft industry, and will not change no matter how you try to justify it. Just follow the practice, no pencils period. If you want to do it, do it, but don't lead others a stray because your being stubborn and foolish. Buy a couple fine tip felt marking pens and be done with it, just don't waste you money on Sharpies. Pilots are good, the German made ones are the best, better tips, keep writing and last a long time. I've made the attempt to alert builders to the practice, they can do what ever they want but I hope they follow the practice - no pencil on aluminum. jerryb > > >oops I was reading the chart upside down, 6061 is actually a bit more >anodic then 2024... so its worse not better > >here is the chart, from worse to better, graphite is the worst, so >deffinately don't use a graphite pencil. > >The Galvanic Table > >Active (Anodic) > >Magnesium >Mg alloy AZ-31B >Mg alloy HK-31A >Zinc (hot-dip, die cast, or plated) >Beryllium (hot pressed) >Al 7072 clad on 7075 >Al 2014-T3 >Al 1160-H14 >Al 7079-T6 >Cadmium (plated) >Uranium >Al 218 (die cast) >Al 5052-0 >Al 5052-H12 >Al 5456-0, H353 >Al 5052-H32 >Al 1100-0 >Al 3003-H25 >Al 6061-T6 >Al A360 (die cast) >Al 7075-T6 >Al 6061-0 >Indium >Al 2014-0 >Al 2024-T4 >Al 5052-H16 >Tin (plated) >Stainless steel 430 (active) >Lead >Steel 1010 >Iron (cast) >Stainless steel 410 (active) >Copper (plated, cast, or wrought) >Nickel (plated) >Chromium (Plated) >Tantalum >AM350 (active) >Stainless steel 310 (active) >Stainless steel 301 (active) >Stainless steel 304 (active) >Stainless steel 430 (active) >Stainless steel 410 (active) >Stainless steel 17-7PH (active) >Tungsten >Niobium (columbium) 1% Zr >Brass, Yellow, 268 >Uranium 8% Mo. >Brass, Naval, 464 >Yellow Brass >Muntz Metal 280 >Brass (plated) >Nickel-silver (18% Ni) >Stainless steel 316L (active) >Bronze 220 >Copper 110 >Red Brass >Stainless steel 347 (active) >Molybdenum, Commercial pure >Copper-nickel 715 >Admiralty brass >Stainless steel 202 (active) >Bronze, Phosphor 534 (B-1) >Monel 400 >Stainless steel 201 (active) >Carpenter 20 (active) >Stainless steel 321 (active) >Stainless steel 316 (active) >Stainless steel 309 (active) >Stainless steel 17-7PH (passive) >Silicone Bronze 655 >Stainless steel 304 (passive) >Stainless steel 301 (passive) >Stainless steel 321 (passive) >Stainless steel 201 (passive) >Stainless steel 286 (passive) >Stainless steel 316L (passive) >AM355 (active) >Stainless steel 202 (passive) >Carpenter 20 (passive) >AM355 (passive) >A286 (passive) >Titanium 5A1, 2.5 Sn >Titanium 13V, 11Cr, 3Al (annealed) >Titanium 6Al, 4V (solution treated and aged) >Titanium 6Al, 4V (anneal) >Titanium 8Mn >Titanium 13V, 11Cr 3Al (solution heat treated and aged) >Titanium 75A >AM350 (passive) >Silver >Gold >Graphite >End - Noble (Less Active, Cathodic) > > ________________________________________________________________________________

John A and Gang: I think it does some good. My wing ribs were built in 1992 with carbon steel rivets. The rest of the wing was built with SS rivets. This was before Old Kolb started using SS rivets. I was concerned about the carbon steel rivets and each one got a big dab of epoxy chromate primer. 2001 I started the rebuild of the left wing after both wings got thoroughly saturated with rain water for two weeks leaning up against the side of a hanger. I found no rust or corrosion caused by the rain, but I did find some corrosion inside the aileron from bug crap. Not bad and was easily cleaned up and primed. I do not know if there was galvanic or dissimilar corrosion or not. When I removed the PT-17 pitot/static system from my lift strut, nickle plated brass on extruded aluminum lift strut, attached with SS rivets, there was quite a bit of corrosion. I new this before I removed it. I could see corrosion under the paint around the fitting. The above was over an 8 year period. john h ________________________________________________________________________________

I liked using ink that wipes off with MEK. Sharpies wear out fairly quickly, but they're cheap and you can get them anywhere.

Without getting harsh about it...............it's common practise to avoid pencil, which has been made very clear here lately. 'Nuff sed ! ! ! A couple of other things - the comment about lubricating the rivet puller from time to time is a good one. There's also an adjustment on the top side to give a tighter grip. I have a medium priced blue ripple finish rivet puller that I bought years ago, and have used it to pull each & every rivet - supplied by TOK - in "almost" completed Vamoose, including, with difficulty, the 3/16" rivets. No name on it, so I can't tell you the manufacturer. Still pulls like new. Using an extra fine felt tip pen on aluminum works extremely well. Use a very light touch and it'll last a lot longer. DO NOT use it on powder coating ! ! ! ! ! ! It soaks in, and doesn't remove with any method I've tried. How do I know ???? Now, for the war................I DO use pencil on powder coating. It erases easily, and no danger of corrosion, or whatever. Like it or not..............this has worked very well for me. Big Lar. Larry Bourne Palm Springs, Ca.

What I found when building the RV's the Sharpies would mark a lines a few times and then they don't want to write well and would skip badly after that. Apparently they pick up something off the metal, oil I assume. The Pilots are better but you can't beat the German Stabilo brand. They have a reddish color case. I just can't say enough about them other than I having a harder time finding since a graphic arts store in our area closed. They work great and last a long time. I found the fine points to be the best, the extra fine tips are good if you need very narrow precise lines but the tips are not nearly as durable. The Fine tip still produces a very sharp line and use them the most. Available in many colors. Acetone (safer) and MEK will remove the ink. jerryb > > >I liked using ink that wipes off with MEK.

I sit back and enjoy the different posts on this list. I also grew-up knowing not to use pencil on aluminum. My A&P school also stressed that idea. But over the years I started questioning a lot more stuff and started requiring the reason behind it. I just took the time and looked up the pencil answer: AC 43.13-1B Acceptable Methods, Techniques, and Practices - Aircraft Inspection, Repair & Alterations Page 6-18 Para 6-91. CORROSION CONTROL WORK PROCEDURES. The effectiveness of corrosion control depends on how well basic work procedures are followed. The following common work practices are recommended: a. If rework procedures or materials are unknown, contact the aircraft manufacturer or FAA authorized Designated Engineering Representative (DER) before proceeding. b. The work areas , equipment, and components should be clean and free of chips, grit, dirt, and foreign materials. c. Do not mark on any metal surface with a graphite pencil or any type of sharp, pointed instrument. Temporary markings (defined as markings soluble in water or methyl chloroform) should be used for metal layout work or marking on the aircraft to indicate corroded areas. d. Graphite should not be used as a lubricant for any component. Graphite is cathodic to all structural metals and will generate galvanic corrosion in the presence of moisture, especially if the graphite is applied in dry form. e. Footwear and clothing should be inspected for metal chips, slivers, rivet cuttings, dirt, sand, etc., and all such material removed before walking or working on metal surfaces such as wings, stabilizers, fuel tanks, etc. f. Do not abrade or scratch any surface unless it is an authorized procedure. If surfaces are accidentally scratched, the damage should be assessed and action taken to remove the scratch and treat the area. g. Coated metal surfaces should not be polished for aesthetic purposes. Buffing would remove the protective coating and a brightly polished surface is normally not as corrosion resistant as a non-polished surface unless it is protected by wax or paint. h. Protect surrounding areas when welding, grinding, or drilling, to prevent contamination with residue from these operations. In those areas where protective covering cannot be used, remove the residue by cleaning. i. Severely corroded screws, bolts, and washers should be replaced. When a protective coating, such as a cadmium plating on bolts, or screws, is damaged, immediately apply an appropriate protective finish to prevent additional corrosion damage. Please keep the banter going but try and add some touchable reasons behind it.

Can't say. I do know the demo is impressive................weld up the hole, and stab at it with an icepick, and you can collapse the can without puncturing the weld. Pretty neat, and I paid a pretty good price for the stuff. Just for the record, I've been saying "weld", but the stuff is really a fluxless solder. They advertise it for all non-ferrous metals, but I've had poor results on brass and copper. It's extremely strong, very hard and melts at about 1100 F., just under the melting point of the aluminum you're repairing. You MUST clean the metal with a stainless steel brush - gotta be stainless. Then you MUST use a propane torch. Mapp gas, or oxy-acetylene adds oxygen, and ruins the job. I'm also very familiar with cold solder joints, and the like. Bitter lesson................maybe all this'll save someone else a similar headache. Then again, as in the demonstration, I've taken stripped out aluminum threads, drilled them WAY out, (the stuff will bridge a 3/8" hole) put in a steel bolt, and with care, time, and difficulty, filled the hole with this stuff, cooled it, broke the bolt loose, and had better threads by far than the original.

I think that the wingfolding mechanism on these things don't line up exactly the same every time because the wings contract and expand with temperature changes. Just like a large piece of aluminum would. It helps if you have a little slop in the attachment tubes holes, or use a little larger tube than you need through the tail boom.

Here's another old story, from bn...the old one. In the mid sixties a DC area man built a beautiful Thorp T-18. He was such a perfectionist that he could pick nits off of gnats. In painting the prop tips with stripes, he could not seem to get a really sharp edge between the colors and the polished alum prop, using masking tape. So he merely used a sharp blade to neatly cut the tape, right on the prop face. While on an early test flight (it is surmised) he encountered severe vibration, with the engine being torn out of its mount, causing the plane to do a couple of whip stalls before crashing---killing the pilot. Investigation showed prop blade failure ALONG the scribed line. The tip was never found. As a stained glass maker, I know what a scratch will do to glass--in fact that's the way to "cut" glass. So leave that hook scribe in your rollaway when you're laying out on most metal. bn the old one ________________________________________________________________________________

I can tell you from my experience flying a Drifter (tail dragger) with a 503 and belt drive both the engine and the prop turned in the same direction. At full throttle you had to hold all most full left rudder until the tail came up then you needed to get out of the rudder fast kick right then hold left to keep it on line. This was always lot of fun on a bumpy runways. The torque of both the engine and the prop heading in the same direction really affected this craft given that it had a long nose and you sat farther out then a Kolb Ken James Drafting Design Instructor Berks Career and Technology Center 3307 Freidensburg Rd.

performance
From: Richard Carlisle <rrcarl(at)concentric.net>
Thats true....For an engine to make its rated HP it needs to run at a certain RPM. For instance, my 503 makes 64.8HP at 6750 RPM. At 5000 RPM it makes around 52HP. A Subaru conversion might make 110HP at 5200 RPM. The problem is that when you go direct drive, you cant run the engine at the RPM that makes the best power. The same Subaru engine that makes 110HP with a gear redux at 5200 RPM might only make 60HP at 3200 RPM. Of course your max RPM is deternimed by the prop diameter. Larger props have to turn slower. Some of the engine conversion companies are making cam and compression mods to increase low end HP and torque for people who want to run direct drive. As far as Jabiru goes, you would need to look at the HP and torque curves for en engine with a redux and one without. That will tell you how much you are losing by going direct drive.

performance I can't speak with any great knowledge on Jabiru or Rotax but..... I have 1st hand experience with a VW engine that has been used with and without a reduction drive. The VW engine I'm using has a cruse RPM of 3100 RPM. With a engine turning that may RPMs in direct drive mode you have to use a small diameter prop to keep the tips form going super sonic. I used a 60" prop and it was a bit too long. The same basic engine with a 1.6 to 1 reduction drive turning a three bladed 72" prop will produce twice the static thrust. There is a trade off though, In our slow speed Kolbs it is only a minor problem. The speed range that the prop will operate in is much more limited. My direct drive engine maxed out at 3500RPM static and 3550 in flight. The reduction drive is maxed out at 3300 static and turns 3800 at 85MPH plus and may still have more speed and RPM potential but this is my limit on engine RPM.

I had a little ground accident while trying to adjust a cantankerous carb on a 503 equipped Mk-2.

Is there a material that I can use (some kind of plastic filler) to fair in the leading edge tube. I believe that will fix that wing. The other wing will be a different story altogether as I can see at least one main rib that is damaged.

I wouldnt fill the dent. Once a tube is dented, it creates a weak point. The tube is more likely to fail at the point where it was dented. For the cost of aluminum tubing, I would just replace it. As far as the rib goes, I dont see a problem with cutting the flange as long as the rib in question is a full rib and the rib tubing runs full width. If I had to do this, thats the way Id do it. I would split the flange horizontally, not vertically. You might also try splitting just one side. You may be able to twist the flange with one side split just enough to get it over the spar.

Richard, If your 503 is making 64.8hp at 6750rpm, you must be using a R&D aftermarket pipe. If this is the case I doubt if your engine is making 52hp at 5000rpm. This is because the pipe you have will give you an increased power band at higher rpms. Normally the midrange hp suffers if the pipe is tuned for high hp rpms. So, I would venture to guess that your engine loses considerable hp around 6000rpm. I bet it actually has less hp at 5000rpm than a 503 with a stock exhaust (because it is "off" the pipe). I used to ride dirtbikes and you could get tuned exhausts which would give you the hp at high rpm, mid rpm, or low rpm. Depending on the type of race track or riding you preferred, you could purchase the appropriate equipment. It was a trade off, you couldn't buy the high rpm tuned pipe and expect to have the same hp at lower rpms as the pipes that were tuned for lower rpms. Otherwise they wouldn't even make the other pipes because everyone would be buying the high rpm/hp ones. Just my thoughts, I could be totally wrong.

It wasnt glued on at an angle. Over time the fiberglass looses its structural integrity and twists. For about a month, everytime I flew I would twist it back. It would stay straight for about a day, then slowly go back to its twisted position. One day I twisted it back a bit too far and it came off in my hand. I cut off the remaining and drilled it out. I replaced it with a spring steel spring. On the windshield, the thickness depends on the curvature of the windshield. flatter windshields need to be thicker. A windshield with some curve can be 1/8 or so. The curve will add rigidity to the windshield so a lighter material can be used.

It is on a tuned pipe. I might be a little off on the cruise HP, but not far off. I remember it being in the low fifties according to the dyno chart. The engine is very strong above 5000 RPM, below 5000 it starts to fall off. That pipe is on my Phantom... The one on my Kolb is a bit different. The effective RPM range is a little higher. It falls off at about 5300 and does not seem to make the power the Phantom does. I had an issue with the Phantom pipe, so after Rob fixed it, he put it on the dyno. Thats why I know the exact performance figures on that particular pipe. I can say one thing. The Phantom definitely makes more power at 5000RPM with the tuned pipe than it does at 5000RPM with the stock pipe. Im not so sure about the Kolb. I havent flown it enough to really get the feel for it. One thing to consider. The R&D pipes are "tuned", but not to the extent that a snowmobile or dirtbike pipe would be tuned. I think Rob has done a good job in designing a pipe that increases power without too much midrange sacrifice and no effects at all on reliability.

From: ul15rhb(at)juno.com
I used .090" lexan on my Firestar windshield. The old epoxied fiberglass can be removed by heating the metal slowly with a heat gun (I actually used a propane torch because I didn't have a heat gun back then). Use a pair of vise grips to get the rod out once heated. It should twist right out if there are no rivets or bolts. It can be heated on the fabric covering the tailpost lower tube being careful not to burn it. I don't think TNK will supply another fiberglass rod, so the new one will have to be bolted in. I had to replace mine once with another fiberglass rod. This one was epoxied in without any bolts. It has lasted all these years. The last 3 years I've taken the load off the tailwheel when not flying and sitting in the garage.

This is an area where personal preference plays the major role. Rick has a 1.6 to 1 re-drive and has decided on a personal limit of 3800 rpm for his engine. I've got a fairly similar engine, but with a 2 to 1 re-drive. I plan on a personal limit of 5000 rpm for my engine, and a 3800 rpm cruise. Before the re-drive broke - on the 1st full power run to 4800 rpm - I found that the engine is smooth and very strong at 3800. ( Local dune buggy racers run similar engines up to 7500+ rpm, with surprisingly good reliability ) At times, I'll probably stress my engine more, but have more available horsepower - if I can keep the re-drive in the thing. ( Looks like I may have to throw this one away, and go to another brand. ) Rick is going for a more conservative approach that will give him much more available power ( torque & thrust ) than he had with direct drive, and still be fairly gentle with his engine. My feeling is that mine will be a real rip-snorter, and his will be more reliable, while still giving excellent performance. Gonna be interesting to see how it all comes out.

With a small opening in the fabric you can screw on an whip ant. with a 45-50 degree bend.

Subject: Re: Crush plates
What I found with my Powerfin 3 blade, ground adjustable was that in adjusting the prop twice I began chewing the outer half of the prop hub on the Powerfin by repeated torquing and loosening the bolts. Stu said I didn't have to use the hi-collar locks that were doing the damage but if not, to safety wire. My cure was this. I made 6 thin stainless flat washers to go under the 6 outer allens that lock the blades and used the crush plate from Rotax to protect the hub from the long through bolts that mount the prop itself to the PSRU drive flange. Before using the furnished crush plate, I chucked it up in the lathe and lightened it somewhat. Left it the original O.D. to catch as much of the outer hub as possible preserving the "sandwich" effect. I drilled all the bolts (12) for safety wire and use no nuts on the flange thru-bolts. By the way, I also have a 2 3/16" prop spacer and am running a "C" box w/3.47 gears on a FSII. I did notice in an Experimenter issue some time ago that Harry Whiting said that the use of a crush plate was a must regardless of the type or material of the prop. Looks to me like its use would spread the effective bolt torque evenly over the whole prop hub. That's my contribution to the "for what its worth" department.

Can't comment on the bobber gauge other than how are you going to see it if you can't see the tank now? Do you have an EIS? If so you could add a capacitance probe (not cheap ~ $100 probe) to each tank and switch to switch between to the input of the EIS - or a panel analog steam gauge. Note, there are differences in the probes for the EIS and the steam guages. If you go with the steam gauge, see if you can get a gauge that is compatible with the EIS probes just incase you want to go to an EIS in the future. Check with Sky Sports and Grand Rapids Technologies. IF your tanks self equalize, you could possibly get by with one but since there top picks I would have some doubt about this. jerryb > > I have a Firestar II with 2 5gal tanks.

I use standard prop bolts that are drilled, I use castle nuts with cotter pins so I don't get any chewing of the prop hub. As for the need of a crush plate I took Stu's recommendation to not use the crush plate on their Power Fin prop. The original discussion was driven because the crush plate covered the Power Fin adjustment windows. I feel the prop manufacture would be the best judge of the need for a crush plate. My general rule on my plane is, if it isn't needed I leave it on the ground. My $.03 cents worth Rick Neilsen Redrive powered MKIII >>> dixieshack(at)webtv.net 01/23/02 06:37PM >>> Shackelford) What I found with my Powerfin 3 blade, ground adjustable was that in adjusting the prop twice I began chewing the outer half of the prop hub on the Powerfin by repeated torquing and loosening the bolts. Stu said I didn't have to use the hi-collar locks that were doing the damage but if not, to safety wire. My cure was this. I made 6 thin stainless flat washers to go under the 6 outer allens that lock the blades and used the crush plate from Rotax to protect the hub from the long through bolts that mount the prop itself to the PSRU drive flange. Before using the furnished crush plate, I chucked it up in the lathe and lightened it somewhat. Left it the original O.D. to catch as much of the outer hub as possible preserving the "sandwich" effect. I drilled all the bolts (12) for safety wire and use no nuts on the flange thru-bolts. By the way, I also have a 2 3/16" prop spacer and am running a "C" box w/3.47 gears on a FSII. I did notice in an Experimenter issue some time ago that Harry Whiting said that the use of a crush plate was a must regardless of the type or material of the prop. Looks to me like its use would spread the effective bolt torque evenly over the whole prop hub. That's my contribution to the "for what its worth" department.

Nope...I saw Boyd's web site. The problem is that (1) I have no idea how to tune an antenna and (2) My radio wont be here when I layup the fuselage. Im afraid Ill end up glassing in an antenna that doesnt work. When you build your own, you have to tune it with the radio that will be in the plane. Been talking to LongEZ and VariEZ builders. A few of them got the antennas glassed in correctly but most of them ended up mounting external antennas because their homemade antennas didnt work. One thing I noticed about Boyd's installation is that he is not glassing the antenna into the cowl. He just tapes it up underneath. Also...The reason he is getting noise could be because the antenna is too close to the steel cage. I figure if I buy a manufactured antenna, its one less thing to worry about. If I were not glassing this thing into the skin, Id be a bit more willing to experiment.

SWR = Standing Wave Ratio Actually it "does" nothing. It is a measurement of the "CONFLICT" between the out-going and the in-coming energy created by activating the TRANSMIT button on a radio. If the "conflict" is too great, the radio will stop transmitting (due to the burned-out parts in the radio). It really is very important to "set" the SWR correctly, and YES, it can be done by a novice, if done carefully.

Gary: Yes, tuning the radio to the antenna is quite essential. As an amateur radio operator, (Boyd Young and Skip Staub, you can jump in here any time), I have learned that tuning the radio to the antenna is similar to using the transmission in your car. You can have the most powerful, turbo-charged engine in the world, but if try to drive around without tuning the engine to the drive train by shifting gears to match the torque of the engine to the wheels, you lose out on the reason for having the powerful engine in the first place. By tuning the antenna to the radio, you allow the greatest amount of power the radio is capable of transmitting, be radiated to the antenna and therefore, you receive the greatest benefit. Tuning also helps peak your reception. Unlike automobile transmissions, a radio only has one gear. However, what you are doing by tuning the antenna is making sure the antenna is in the proper gear ratio for the radio to operate efficiently. Even if you cut the antenna to the exact prescribed length according to the intended frequencies, there are outside influences like all those pieces of aluminum tubing and steel flying in formation nearby that can throw your antenna out of tune. I know many of you likely are not interested in purchasing an SWR meter just for one goofy measurement. For those individuals, you may be able to hook up with a local amateur radio operator for a simple SWR check. He or she would probably be interested in your project anyway, or at least have a few good laughs.

Just place the vacuum outside and run the hose inside...there is enough pressure to allow air to push out around the face seal. I feed the garden hose under my belt and can move around with some restriction bacause of the stiffness of the hose. I haven't tried a compressor hose but it may work even though the volume would not be a available through the smaller hose.With a vacuum cleaner there is no risk of oil contamination from compressor oil.

<<<<< Can someone explain in layman terms what the swr is and just what it does? Where do you get it and is it expensive? Can anyone use it or do you have to have a degree? I saw the question about a cb swr being used on aviation antennas, didn't see an answer yet. Dallas Shepherd cen23954(at)centurytel.net>>>>>> swr stands for standing wave ratio and in easy terms you dont want any. to help you visualize it take a 20 to 30 ft piece of rope and tie it on to a door knob. hold the other end and pull it fairly tight. quickly raise and lower your hand.... you will see the energy travel down the rope as an energy wave, to the end tied to the door knob and the energy wave will travel back to your hand. your hand will then have to absorb the returned energy. the energy coming back is swr and you dont want any. your radio sends out electrical pulses down the coax to the antenna. if the antenna is not the correct length to absorb the energy and cause it all to be sent into the air as static and magnet pulses (radio waves) or if there are other factors which cause the energy (or some of the energy) to be sent back down the coax, you will have high swr readings. all the energy that is sent back down the coax is used up in the radio as excess heat. and remember transistors don't like excess heat. too much and the smoke leaves the transistor and it wont work any more.... remember all transistors work on smoke. when the smoke is let out they quit working. and heat causes smoke. boyd ________________________________________________________________________________

All this talk about SWR brings me to another question. Peaking and tuneing your radio. Is this really worth the effort? Does it make a big difference? Thanks thumbs peak and tune the antenna keep your cotten picken hands out of the radio boyd ________________________________________________________________________________

<<<<<>>>>> some cb swr meters will work and some wont.... ask me how i know. radio shack has a small swr meter about 2 inches square that cost (i am guessing now i bought mine several years ago) about 50 dollars. it is designed for tuning the vhf ham radio frequencies. 144 - 148 mhz. it is not 100% accruate but is verry close. i use a mfj antenna analizer in conjunction with the meter. if it saves sending a radio in for repairs it is worth the cost. boyd ________________________________________________________________________________

I have used plans that I obtained from this list to make skis for my Firestar and I am about ready to try them as soon as the conditions permit. Here is my question for all of you hardy winter flyers. What are the do's and don'ts of flying with skis? ________________________________________________________________________________

Dwight, i think you got the same plans as i have from my flying partner Ralph, there are a few things that i can tell you and i'am sure others will contribute more. make sure your ski tips are about 5-7 degrees higher than the rear when the plane is suspended on jack stands or whatever. this would be like putting a 5" or 6" object under the front of the ski for the proper pitch for me---and of course the length of the ski makes a big difference. i myself did not find any problems from wheels to skiis, in just taking-off it tracked easier and in landing in was very smooth assuming you have a good base 5"-6". be careful because too much snow and you seem to want to nose over easier. watch for those 4-wheeler tracks cross ways because they can make some pretty big ruts---do a low pass first to make sure you have a good landing site. also we use a teflon spray on the bottom of our skies as it will give us a low coefficient of friction. apply it before you put your skiis on it is alot easier and it will last 25-35 landings depending on the condition of the snow (wet, sloppy, sticky) etc. have fun, there are alot of little lakes and fields to be explored. http://members.ebay.com/aboutme/s.o.s/ thanks, Gary r. voigt kxp model "Kottke, Dwight" wrote: > > I have used plans that I obtained from this list to make skis for my > Firestar and I am about ready to try them as soon as the conditions permit. > Here is my question for all of you hardy winter flyers.

Winter flying what fun cold it is!.. Understand this info comes from flying in the north East winter in a non powered Hangglider. But what I have to tell is will still be valid for low and slow! 1 Get a good pair of winter sun glasses NOT DARK shade type, I prefer green tint, the need for lighter color is due to the lack of shape definition due to snow covering, your perspective will be thrown off!!! You will not be able to see holes dips or other nasty surprises until you are right on top of them. This is due to the low contrast that snow cover gives. 2. As vitally important dress warm but do not over dress. If you sweat on the ground it can kill you in the air. 3. If you cannot move normally with your heavy covers on you may not be able to reach the right switches in time another killer! 4. Drink more water than you might think this will help in the cold dray air! 5. Double check your landing site. It's very hard to pick out dangerous things on snow covering ( I know I'm repeating) 6. Finally double check every thing you need to touch with your gloves on. If you're in a pusher don't even think about taking them off unless you have it clipped or tied to your sleeve.

your right Dwight, i should have a ski for the tail dragger but i have never put one on and never needed to because i usually get the tail up right away on take-off and perform a ski landing only. also here on lake minnetonka in mn. the area gets packed down real fast by the sleds. i have landed and taken-off in 10"-12" of snow and what happens is the tail wheel just drags along and the snow flys a little more. I have been meaning to put one on but i will wait till next year when we get more snow. some people put a board on the bottom of the tail wheel rod so the tail wheel is off the ground. let me know if i can help. http://members.ebay.com/aboutme/s.o.s/ thanks, Gary r. voigt kxp model
