         If the speed is cut in half by the gearing, the Torque is doubled, ie, 
      TXSXK=Hp
      
      in other words the horsepower remains the same, but the speed and torque are 
      modified, ...actually the output HP is reduced by the efficiency of the 
      gearbox, for a very efficient gearbox, the Hp would be nearly the same as 
      without it. But bear in mind the thing that is enabling any HP at all to 
      happen is the coupling of the prop with the air...which is another story 
      altogether. In other words if you don't have a resistance against which to 
      have torque, you don't have any HP at all, do you...see how Hp = 0 when T = 
      0. And what happens when the prop tips break the speed of sound....does that 
      require a lot more torque....dunno but I bet it does and the poor Rotax is 
      putting too much of its Hp output into the tips and not into properly driving 
      your airplane....this is coupling of the prop to the air.

1. If you reply to a message and change the topic, please edit the subject field to reflect it. Makes following a thread by topic easier plus us old farts have a hard time finding things later. 2. Plugs, try a set of new plugs - remove the old plugs keeping track which cylinder they were removed from - read the color of the plug - a light brown is good, the darker it gets the richer that cylinder is running. Note: I've found that usually the hot cylinder is the problem cylinder. This may not always be true. Any type of leak, intake, exhaust, or cylinder will cause a EGT rise in the cylinder. 3. Probes. If possible swap them between cylinders - getting them out sometimes can be a bear. Don't damage them trying to get them out. You can switch the wires are the gauge. 4. Are the carbs positioned correctly in vertical plane (top of carb rotated forward or back in the boot) when the plane is in its flying attitude, example a tail dragger sitting at rest on the ground the top of the carb(s) will appear to be rotated slightly to the rear. 5. If two carbs, are both set to at the same vertical orientation. 6. Intake or Exhaust manifold leaks - torque the intake and exhaust manifold folding the torque procedure - this involves a criss-cross pattern and do not tighten each bolt down all the way. Gradually tighten them following the criss-cross pattern to get them to tighten down flat. 7. Head gasket leaking - looks for small oil leaks around each cylinder. Note, there can be slight miss match of airflow through the carb into each cylinder, some times it is necessary to rotate the carb just slight to cure this. jerryb > >What would cause a difference of 100-150 degrees between front and rear EGT? > >Jim >Mark III >Charlotte, NC > >----- Original Message ----- >From: "Richard Pike" <richard(at)BCChapel.org> >To: >Sent: Sunday, August 05, 2001 11:55 AM >Subject: Re: Kolb-List: How are HP and Torque related > > > > > > Assuming a healthy, correctly jetted engine, EGT's will normally go too > > high when prop load is insufficient, and may go too low when prop load is > > too great. > > There is more detail on the web page > > http://www.bcchapel.org/pages/0003/pg11.htm > > Richard Pike > > MKIII N420P (420ldPoops) > > > > > > > > >4.

Subject: Re: Temp difference
Faulty EGT gauges. Ignition variance between cylinders. (Bad spark plug caps, bad wires, flawed timing, failing components) Mechanical variations (leaks, stuck rings, gross difference in ring gap, gross difference in carbon accumulation) For dual carbs only: uneven jetting, incorrect float levels, clean/dirty air filters, one carb has hung enrichment circuit, one does not. I would first switch EGT wires and see what happens. My gauges typically run 100 degrees different, but I know which one is constant and which one is "flakey." If there are no other apparent answers, run a pressure/vacuum test on the engine. California Power Systems sells a tester, it is not cheap at around $100, but you can get a couple pals to go in with you on one, you need to test your engine annually anyway, so go ahead and bite the bullet.

Subject: VW Powered MKIII Update
For the last year I have been pursuing my idea of the ideal replacement for my direct drive VW engine. Well there is no IDEAL engine. What I have decided to do is replace my direct drive VW for a belt drive reduction VW engine. On Saturday I ordered a new replacement engine from a engine builder in California. The new engine will be built with mostly forged racing parts but with a Eagle 100 cam and hydraulic lifters. The new engine will be set up to run the run the same 3,000 cruise RPM that I'm running now. Shortly I will order a 1.6 to 1 belt drive reduction from Gene Smith with a prop shaft extension. I will then order a 72" three bladed Power Fin type F prop. The costs are as follows: Engine $3325.00 Reduction Drive $1300.00 Prop $575.00 I will have a new long block engine that I will move my carburization, ignition, exhaust, and misc parts to. I will then be selling the old Great Plains direct drive engine. I was seriously considering the chain reduction drive that Larry Borne and Julian Warran are going to use but???? There are issues with both choices but the belt reduction drive is a long term tested and proven unit. Thanks very much to Larry and Julian for you assistance. I will keep you informed of how it goes. Rick Neilsen VW Powered MKIII ________________________________________________________________________________

Subject: Chuck Veith Update
Date: Aug 04, 2001
I met with the family over the weekend and learned more about the accident in the Kolb Slingshot on 7/24/01. A third witness has come forward--this individual actually saw the crash. Chuck was preparing to land coming in with the wind when the engine stopped--her made a 180 degree turn into the wind and was gliding into a grassy--mostly level area about 4 city block square. The area was cleared and being prepared for a housing development. At less than 100 feet Chuck made a sharp left turn and stalled. the emergency landing area had dozens of small steel fence posts(the kind you hang electric fence wire on). We believe that Chcuk did not want to damage his plane and he tried to turn to land on a gravel service road. If he would have landed he probably would have had some damage but would have lived. Lesson here is do not attempt turns at low altitude with an engine out. Bettie went to a seminar at OshKosh where Rod Machado reported that no one had died on an engine out on take off if they land strainght ahead--all the related deaths came when people tried to turn. The left gear leg hit first and was sheared off the plane--the left side of the cage and the left wing then hit--bounced and slid then on the nose and finally came to rest upside down. Chuck had multiple severe injuries and internal and external bleeding. I had hoped that wearing a helmet would have saved him but the doctors said no helmet would have worked. The engine has been taken to Chicago and will be examined by NTSB. The lesson here for all of us is do not try turns at low speed during engine outs. We as pilots are taught to fly the plane in emergencies but there comes a time when we realize that we need to try to survive the imminent crash.

Subject: Re: Gas tanks
I have two 5 gallon tanks sitting side by side, instead of in tandem as you do. I draw the fuel out through the gas caps, which I have drilled a hole through for the fuel line. The holes are larger than the fuel line to allow venting of the tanks. I have a tee installed just above the tanks, then go to the primers, fuel filter, then fuel pump. After flying I can fill one tank, leaving the other one half empty, and when i come back, they have equalized. A siphoning effect takes place between the two. Also if I takeoff with one tank full and the other half full they will equalize during flight, both siphoning and the fuel being drawn from the tank with the most fuel. With the tandem arrangement of your tanks, depending on your cruise attitude, the tank that is the lowest will have the mostest fuel. Asuming you set it up like I do. >>> jhankin(at)planters.net 08/03/01 08:34PM >>> A friend of mine has a Firestar with two five gallon tanks, one placed behind the other.

Hello Fellow Kolbers. Because I have completed and am now flying my new Firestar II, I want to sell my Firestar KXP. I just can't fly both at the same time and besides I need the room in my hanger. It is the KXP model (Heavy duty). 503 SC DCDI Full enclosure Instruments are CHT, EGT, Tach,Compass,fuel gage, Electric in flight Ivo three blade Prop (Colored) to match the trim. In flight mixture control. Apx. 9 gal fuel tanks. Wheel pants. Custom (comfortable seat). Has always been hangered 275 Hrs total on engine and plane. Of course it is Stitts covered and is White with Cub Yellow trim. Has won the Copperstate award for "Ladies choice" ( Have a plaque to prove it) This is the plane that I flew back to Missouri a few years ago from Arizona. I covered several States and had no problems. It averaged 2.8 Gals per Hr on that trip. It has never let me down. Wife says to "get rid of that thing" so it has to go. I do think it is a safe and solid buy for someone wanting a solid troublefree plane. Answer to eagle1@cervnet or call me at (928) 776 9543. I am located in central Arizona at Prescott.

Listers, I would agree with Dales advice if you are not familiar with doing dead stick landings with your plane. However, a turn at 100 ft is the same as a turn at 1000 tt (other than the fact that you might not recover from a stall at 100 ft.) The point I am making is that if you practice dead sticks to the point of proficiency, doing a turn at 100ft will not be a big deal nor deadly. Due to a period in my life when I was doing some "unusual" modifications to my engine, I experienced quite a few unintentional dead sticks. Most of them required last minute corrections due to previously unseen ground conditions, like ditches, termite mounds covered with grass ect. I performed many corrections at low alttude, once I did a 220 degree turn from about a 150 ft after an engine out on climbout at River Ranch with a canal & swamp in front. At no point was I endanger of stalling because I was flying my established paramaters that I often practiced. I originally was going to only do a 180, but it became apparent that I would be rolling through a ditch perpendicular to my path, so I continued to turn untill just before touch down. I hit the ditch at almost a 45 degree angle & only slightly bent one gear leg. That was in my old UltraStar which I often gained altitude on engine offs coaxing FL thermals. If I was in my present SlingShot & the wind was strong, I might have only been able to get a 90 or only 45 degrees out of that 150 ft. The point I'm trying to make is that if you are familiar with your craft & you are flying the numbers you've practiced before (& not ding high G turns) you will never stall your plane& bend your gear or crash your plane because your engine is not running. Your plane could care less if the engine is running as long as she has the airspeed (or angle of attack for you purists.) Nothing magical happens that changes the laws of physics when your engine stops running. You just continue to fly your plane by the numbers you practiced & do what you can do with the alttitude you have. And a pilot that has practiced dead sticks so they are routine, will be in a much better position than a pilot who is experiencing an engine out for the 1st time, whose presence of mind will be definitely affected in a way that hinders decision making.

Subject: Re: How are HP and Torque related
I'm seeing the potential of some misunderstanding in this Torque/HP issue. The torque and HP capabilities at the output shaft of the engine stays the same, as well as its horsepower regardless of what gearbox is mounted to it. What has been said is basically right, with the understanding that we are not adding torque to the engine by gear reduction, but harvesting more of it by making the engine operate at higher RPMs where more torque is produced. Gearboxes, transmissions, tires, and props, all rob horsepower. So as has been said, HP is HP, wherever it is measured. As you move through the drivetrain, there is less and less. Rotax and all engine mf'rs measure it before the gearbox for obvious reasons. Look at it this way. You and a friend have the same engine and prop in identical boats except his has a 1:1 ratio and yours has a 2:1 gear ratio. You both want to try and tug 4 waterskiers at once. Say its a 350 chevy engine that makes its best torque at 3500 rpm. Your 2:1 ratio boat pulls the skiers out easily, but only at 20 mph, not fast enough that they can really get up on the skis. RPM's go out of sight. Your buddies boat with the 1:1 ratio drags em forever to get out of the water but once the boat planes and gets on top of the water, the rpms get to 3500 rpm, skiers arms came out of their sockets on the way, but now they are all skiing at 33 mph. Everybody is basically happy except you cuz you can't play. Luckily you have the business card of a guy called Theoretically Efficient Props. He says he has the fix to your problem and forges a prop with a much steeper pitch. You put it on and try it. The four skiers struggle to get out of the water again, but they finally get up, the boat gets to 36 mph and you are happy again. Did the engine's torque capabilities change during all this? No. All that happened was that you changed how you have loaded the engine to perform at its best torque producing RPM. The prop guy made the prop that put your boat in it's peak operating range. Engines that work best for heavy load applications such as the marine application above develop torque early and maintain it throughout the power band. The engine in the boat example isn't the best for this application because it doesn't produce a lot of torque at low rpms to get the skiers out of the water. You either decide to switch to a big block engine, or pull fewer skiers. The relationship between HP and Torque is as follows: HP = Torque X RPM or Torque = HP/RPM. There is no constant in the equation, just a conversion of units. Max HP and Torque do not necessarily correspond at the same point because of varying engine efficiency at different RPM's. Gearbox ratios and prop pitching cheat to do the same thing by attempting to achieve RPM for max HP/Torque. Looking at the relationship how do you get high torque. The biggest number comes from big HP and low RPM. Putting it simply, a torquey engine shows its prowess in providing high HP at lower rpms. 2 cycle UL engines are inherently non-torquey, as the torque and max HP happens at high rpms. While a 460 ford or 454 chev (known for their torquiness) make HP at much earlier rpms and maintain it well through their respective powerbands. Diesel engines are the same (High HP, low RPMs).

Subject: Re: Beauford's ugly plugs
Beauford; for you I have nothing but my best wild guess: Problem definition: If your compression is equal, then it is probably (?) not mechanical. If the spark is correct, and timing is correct, probably (?) not electrical. If you only have one carb, carburetion can not cause an effect like you describe. Therefore, if the plug at the mag end looks too lean, and the plug at the PTO end looks too rich, or else looks like a plug that has been oil fouled and the oil baked on: then one end is getting too little fuel, (or too much air) and the other is getting too much fuel, or more likely, too much oil. I would look for a crankcase leak, specifically - leaking seals. A leaking seal at the mag end would give you a lean appearing plug at the front of the engine. (sucking air) A leaking seal at the PTO end of the engine would cause the engine to suck oil out of the gearbox, and bake it onto the plug. Walk, don't run and check the oil level in your gearbox. If it is down, that is confirmation. In any event, I would suggest doing a crankcase pressure test for leaks. If it needs new seals, DO NOT buy them from Airstar Discount Sales. They will sell you poor quality seals that will fail in less than 20 hours. (Guess how I know this?) That is my best unqualified opinion on the problem. But then...maybe it's because the front side of your air cleaner is caked with boll weevils and love bugs, and the back is not, and the airflow is unbalanced and dividing in the intake manifold.....????

For all the other guys, are you ready for first-time surprises and how will you do when that time comes without any practice? Good Luck ..... because you will need all that you can muster up without going through any rehearsal beforehand under an already tense situation. As Richard Swiderski has said, a Firestar can be landed in a gradual bank all the way to the ground. But how would any of you know this without actually doing it. Real flying is an art and a skill which has been lost over the years as planes have gotten larger and faster. Flying an ultralight affords every one of us that opportunity to relearn those lost skills if you so desire. The Bob Hoovers' and others like him know the real art of flying, but we can't all get in a business turbo-prop plane and do what he does, but we can practice bringing our little planes down safely without the aid of an engine. Yes we can, but only if you want to. In my opinion, there are a lot of good pilots that are very good so long as the engine is running. The better ones are the ones who know how to fly and bring their planes down safely when the engine is not running. Now would you rather have a little practice under your own terms (and your own turf) or try your luck on the first shot? It's up to you.

First, I want to share my sincere condolences to the family and friends of the Oshkosh bound slingshot pilot Chuck. After reading Dale Seitzers post and how he found out about his close friends death at the happiest place on earth really shook both Craig and myself. It brought back memories of close ones we have lost to aviation. Again our sincere apologize. Oshkosh in one word: OVERWELMING!!! First, the weather, We arrived on tue. afternoon and immediately looked for a dive shop to purchase fins and snorkel to navigate through the humidity! Us desert lizards aren't use to that much moisture going into our lungs. After meeting our host that invited us, Tim "TC" Fox (nicest guy in the world) we set up our tent under darkening skies. After getting a shower( showers were great and we never had to stand and wait in line, not even once!) we hit the sack. just as I crawled into bed, it started to rain. It rained all night long and was a nice way to be lulled asleep on our first night at Oshkosh. Wed. we awoke with overcast skies but no rain, 14-20 mph winds from the north were dryer and cooler. Thur & fri.. was sunny and still had the same winds which kept it cool(seventies) and dry. Sat. the winds subsided and humidity came back, bit warmer and overcast with light sprinkling. We left Oshkosh sat. at 4:00pm and it looked eminent for rain. It was nice to meet Kolb and their crew, but not as nice or as much fun that the guys who own build and fly Kolbs Many folks from the list was there and we met Sat. afternoon took pictures and talked for a while. I asked John Hauck if he were to do another Barrow trip? He reported "no more". I then exclaimed the next Big trip is the "I Do" trip? He assured us all that he wanted to keep this relationship healthy and everlasting and not mess it up from the "I Do" syndrome. There were more planes than you could shake a stick at, and I bet in our 5 day stay we only got to see one third of all the planes and exhibits (including Jim and Dondi Miller). The EAA museum was overwhelming as well. We thought we would spend a few hours in there and just about lost most the day in the museum. All and all it was fun and I am hooked!

If you convert to shaft horse power, you must convert units to relate to torque and rpm, but the constant remains." Interesting. I agree that there's a constant involved (someone earlier said there's not), but I've seen the formula given as HP = Torque x RPM/5250. That's why, if you see an engine's horsepower and torque plotted on the same graph, they're always the same at 5250 rpm. So the question is, is the 5250 somehow derived from your 33000 ft/pounds per minute? :) Lee in Ky ________________________________________________________________________________

If you convert to shaft horse power, you must convert units to relate to torque and rpm, but the constant remains." _____________________________________ Um. Yeah. Well. I agree. Sorta. Jack, lets look at where the 33,000 comes from. Science uses the term constant to be a factor with with empirical basis, not definitional basis. I think of constants as the "magic" numbers because there is little but empirical evidence to demonstrate or prove them. Starting again where we left off on the Kolb list 3 weeks ago, looking at the relationship between hp and torque: HP = Torque X RPM As you said, some guy a long time ago found that a horse could exert a force equal to 550 ft-lbs per second and defined this as 1 horsepower. 550 ft-lbs/sec mulitiplied by 60 seconds per minute you get the 33,000 you show. Not a constant such as the gravitational constant "G" that we pilots are always trying to overcome, but a units conversion. Further, lets look at how to translate linear directional horsepower to radial horsepower such as produced by a rotating shaft or at the outer radius of a tire? Using our relational equation between HP and Torque: 1 horsepower = 550 ft-lbs/sec X RPM Lets call rpm our rotational speed and then use our trigonometric friend the radian to define the rotational speed (this is the trick). Using radians per second as the units in our rotational speed: 1 HP = 550 ft lbs X radians/second (notice how the component of force divided by time stays in tact with radians as the rotational component) We are wanting to get back to revolutions per minute in the rotational speed component of the equation so we convert seconds to minutes as: 1 HP = 33,000 ft lbs X radians/minute Then we convert the radians to revolutions by knowing that 1 rev = 2 pi radians to get: 1 HP = 5252 (ft lbs) X rev/min or what we are after 1 HP = 5252 X Torque X RPM Many also use 5252 as the "constant" when it is actually units conversion derived in translating linear directional HP to rotational directional HP.

Herb. Let me know if you find anything for a 5" diameter tail tube. When I got my Drifter, it had a buckled mainframe tube from a hard landing. The only thing I found that was close to 5" aluminum tubing was 5" irrigation pipe, or to buy the stock tube from the manufacturer. Irrigation pipe is made of weaker aluminum and seamed, not extruded. The cost of fuselage tube replacement for the Drifter was $1000 shipped. So $260 is a good buy if you ask me. I don't think you would want to risk the irrigation pipe. I think the mfr's Kolb and Maxair decided on 5" because it was such an odd size, extruded only by special and quantity order, making you have to buy the parts from them. B.J. Moore, P.E.

As in: 2x40?80, and 16/1?16. In the former, I wanted my W*M pill-roller to give (make that sell) me 80mg pills instead of 2- 40s that I take both at once. Pill roller had to call my quack to see if the dosage was the same! In the latter problem, I was stirring up a new batch of motion-potion for the 447, carefully measuring out 6.5 oz of Pennzoil for each 2.5 gal. can, making it 1:50--2.5 gal=320 oz, 320/50=6.4 (close enough). BUT, for the first time I read the label on the Pennzoil pint bottle, and it says: for 16 to 1 ratio, use TWO oz. oilfor 1 gal!....and for 50:1, use SIX oz oil per gal of gas.

It even went up to 100 mph and went between there and 50. After landing it still showed 100. Checked all tubes and inlets. everything looked ok.

Julian, I used a piece of EMT. I welded a nut on the end. This nut receives the bolt from the outside of the pant. It needs to be small enough for the bolt to go inside of the EMT. I had to ream the other end of the EMT out just a wee bit so that it would slip easily over the threaded axle and down against the castle nut holding the wheel bearing in place. I then tack welded it to the castle nut. Be very careful not to get any spatter down in the threads. It is best to force some aluminum foil on the threads just to be safe. Tacking it in place on the axle assures that the EMT will be centered on the axle and not spoil the threads when being installed and removed. I then removed it from the axle and finished welding. L.

Hey guys, I missed ya. Got a question from a Florida buddy. Where is a good location for the static port in a FSII? I'm using an open port on the ASI under the panel for now and plan to experiment later. Ready for engine break-in soon as I get my prop extension back. By the way, before the list crashed I saw a comment about the cross brace behind the pilot's seat back breaking the welds after several hours. I tried merely pushing on my seat back by hand and was able to see quite a bit of bending going on. Looks like getting in and out of the plane is what's breaking those welds. I made a brace from THHN galvanized 1/2" conduit and bolted it in place, tying that brace to the parallel brace ahead of the gear leg sockets that's used for the second seat. Primed and painted it to match the powder coat. Light and strong and looks sorta "factory-like," and took all the movement out. An easy fix prior to cracking for those of you who don't like the idea of welding near that shiny fabric (like me). If your welds aren't cracked yet, I recommed it. It takes the flex out.

Subject: Re: How are HP and Torque related - The constant
Heres my 2 cents worth: 1hp = torque(ft.lb.) X RPM / 5252 this is in a lot of books so it must be correct. Let's use the old water well and bucket for an example. If the bucket full of water weighed 33,000 pounds (big bucket) and the circumference of the drum that the rope rolled up on is 1 foot and you were able to turn it one turn in 1 minute (superman) then you would produce one horsepower. The circumference of the drum is 1 foot so the diameter is 1 divided by PI = .3183' The radius is 1/2 the diameter so the radius is .3183 divided by 2 = .15915' Torque is a distance (.15915) times a force (33,000) = 5252 That's where the 5252 comes from. If you reduced the circumference of the drum to 1/2 foot then it would take 2 revolutions to raise the bucket 1 foot but it would only take 1/2 the torque because the radius is less. A Rotax 582 is 65 hp at 6600 rpm (I think) so the torque would be 51.72 ft.lb. using the above formula. This torque is what is produced at the crankshaft. If we use a 3:1 gear box then we reduce the RPM to 2200 but we triple the torque (51.72 X 3 = 155.16) The horsepower stays the same 2200 X 155.16 / 5252 = 65 Steven ________________________________________________________________________________

Or, set a quart can against the front of each tire. Lay a straight 2x4 on top the cans, tight against the front of each tire. Lay a carpenters square along the outside of a tire and square with the front of the 2x4. Turn the front of the tire in so there is a 1/8" gap between the front-side of the tire and the square. That will give you a 1degree toe-in on a 6" tire. If you don't want any toe-in, just make the square touch the front and back of the tire and be square with the front of the 2x4. Drill hole. Make sure the front-to-back axis of the airplane is at a 90 degrees angle to the 2x4 or you'll track at an angle! :) I did this procedure, after replacing two wheel bearings (the inside bearings don't seem to last long) and I was surprised how far off one of my "eye-balled" wheels was.

I have never had any problems with using safety wire, double wrapped and spun down on urethane tubing as a means of keeping it tight.

Although my FireFly is not "done", I can say it is the most fun thing I have ever done and I could not imagine being without it. Part of the fun thing is keeping it legal and not having to worry about the feds. I can tinker and change to my hearts content with out having to worry about them. The plane is improving as time goes on. It has gone from very heavy in the ailerons, smooth air machine to a two fingers on the stick plane that can be flown any time of the day. Vortex generators eliminated the need for the flaperons and give the plane a high aspect ratio feel. I wear a goggles, a light flight helmet, and an ANR head set. By sitting up front the view is remarkable, and landing approaches, and landings are just like a video game. The biggest disappointment has had nothing to do with Kolb and it is the Rotax 447 engine. For the money you pay for the engine one would think it would like to run at something less than 5200 rpm and push you at cruise at something less than three gallons per hour. But I have discovered that piston ported engines tend to load up and run rough as the throttle is closed and they are not very fuel efficient. In an attempt get a round this last problem, I have ordered a Simonini Victor I, 382 cc, one cylinder, water cooled engine. It is advertised as 48 hp at 6000 rpm, and should weigh 20 pounds less than the Rotax 447. This is supposed to be very smooth fuel efficient reed valve engine. If it is close the published specs, I should be able to fly 120 to 150 miles with a gallon reserve, and this will make cross countries more fun. With the expected weight savings, I will add some streamlining to make it fly a little more efficiently, and may be make a full enclosure for winter. I see you are located at Memphis. I am just up the river from you at K02. If you get this way stop in. If I am not there, you can ask the lineman, and I am sure he would unlock the hangar door so you can take a look at the FireFly.

Vic, Not sure what your situation is, but when I first fired up my 503 it had a lot a air bubbles in the oil injection lines. I tried to pull the pull starter with the ignition off and throttle wide open to get the lines full and didn't have any luck. I went to South Ms. Light Aircraft where I purchased the engine to run it in and I premixed the gas per the Rotax manual for initial start-up. They were not concerned about the air in the oil lines. As soon as the engine started one of the Smith boys immediately held the oil pump arm in the fully open position. The oil was really flowing fast and all the air bubbles was out in a couple of seconds.

BUT, for the first time I read the label on the Pennzoil pint bottle, and it says: for 16 to 1 ratio, use TWO oz. oilfor 1 gal!....and for 50:1, use SIX oz oil per gal of gas.

Check the static connection as well as the pitot connection. To check the pitot connection attach a piece of plastic tubing direct to the pitot tube. s-l-o-w-l-y- roll it up and watch the airspeed indicator. If it doesn't work, remove the pitot line at the indicator and connect the plastic tube to the indicator pitot fitting and try again. To check the static connection start with the tubing rolled up and s-l-o-w-l-y unroll. The airspeed indicator should read upscale.

Well hears my $.02 worth. The Kolb airframe is like the old Timex watches they take a lot of abuse and keep on flying. They are made of aluminum, steel and thousands of pop rivets. Get someone to show you the internal structure of the wing spars and the boom tubes and you will get some idea of the quality of design in these seemingly simple airplanes. We have members that have flown a hundred pounds over gross weight hundreds of hours. We had a past owner that decided he wanted to personally find what it would take to break the airframe. I understand he really had to work at it but he did and then they fixed the weak point. I think the broken wing is still in Homer's hanger. For you own personal feel of the planes get some one to take you for a ride, you will not be disappointed. As for the Kitfox, kind of hard to beat but I have some personal concern for the bonding of the wood ribs to their aluminum spars.

Depending on your skill and curiosity you may be able to overhaul it yourself. Take it apart carefully and see if there is any gear or lever that does not seem to do anything. It does not sound like dirt or obstruction in the pitot tube area but the inlet is probably screwed into the case even though it does not look like it. Grab it with pliers or channel locks to unscrew it and look for any debris. The actual inlet hole is very small. If completed and you want to test it run a plastic hose to the inlet and carefully blow into it. Watch the needle and do not "peg" it to the stops. Blow gently and keep an eye on smooth movement of the needle ________________________________________________________________________________

Hi Gang, Sure is great to have the list up and running again. You don't know what you have until its gone. I've been getting some flight test time on the new Verner installation any time the winds drop below 25 knots or so, which ain't often. Things are going well working through the prop diameter/pitch exercise. But, I believe the thrust line is incorrect. In round numbers the engine thrust line is 5 degrees lower than the bottom of the wing. Of course, it is even lower if compared to the chord line. The bird is flying a bit nose high compared to the old Rotax and takes considerably more power to get any kind of cruise. Haven't been able to glean much from the archives.

Subject: Re: Fun with your 447
You may have to rejet you carb. We're in Texas and had to change the needle and the main jet on our 447 on our FireFly. For some reason the FireFly makes the 447 very sensitive in the mid range area as compared to my Hawk. Just curious, have you tried another carb on it. I had to replace a new carb on my Hawks 447. It was out of the one year warranty so I had to eat it. Talked to Lockwood about it but not much help there. Their weak on carbs. My partner rebuilt it but still didn't work, something in the main body was causing the problem but we never could figure out what. I finally got fed up and ordered a replacement. It cured that problem but by the fuel flow meter it seems to have a higher fuel consumption than the original. Have you got a buddy you can barrow a carb from. Try the main body where you don't have to mess with the disconnecting the throttle cables, or mess with the needle, plastic thingy, clip, and that darn spring. If that doesn't work you can try the whole thing but I suspect there wouldn't be any difference. The problem likely is in the main body. Are your EGT's running near the same or do you have one cylinder hotter than the other. I also had to replace a head gasket on it. Spotted it by slight bit of oil near base of that cylinder. Fixed it. Make sure your exhaust and intake manifold are torqued to correct amount. Use the proper torque sequence. Any slight air leak will usually cause the cylinder to run lean causing high EGT for that cylinder. jerryb > >Jack: >Well said, Sir... I share your disappointment with the 447...

Subject: Re: Fun with your 447
Jerry and Beauford, I believe Beauford and I are both having the same problem. If you put the clip in #2 slot for summer our 447's run too lean, and if the clip to #3 slot they run much to rich. I tried an experiment today. I bought some little #4 flat brass washers. They were .032 inches thick. I placed one on the needle under the clip that is in the #2 slot. I took a spin around the pattern to see what was the effect. No difference in climb out, and on down wind at cruise the EGT's registered 1100 which is the same as before. But upon reducing the throttle the EGT's came up a little but they did not get close to 1200 as before. I could set the throttle at 4600 - 4700 and push the nose down and the EGT's did not come up to 1200. This has me excited about a possible fix and it indicates that there is not enough needle adjustment capability with the present needle and clip system. I purchased some flat brass. I am in the process of making flat inserts that will go around the needle and under the clip so that the throttle cable and spring retainer can pass through just like the present clip but also support the entire lower surface of the clip and the spring retainer. With .025 inch spacers, it should give another three or four finer needle adjustments going in between slots #2 and #3. As indicated by the use of the washer today, it should allow us to get out the peaky EGT area of slot #2. When I get the spacers made and try them out I will let you know how it comes out and I will take pictures that I can put them up on the web. Jack B.

Date: Aug 31, 2001
Just to clarify, the chart on my Pennzoil yellow bottle is not wrong. The bottom row on the Pennzoil label represents gallons of gasoline ... NOT ounces of oil. The chart shows the amount of gasoline (bottom line) to mix with the whole pint (middle line 16 oz) of oil to achieve a particular mixture ratio (top line). Don't know why they did it that way, but check it again, I believe you will see. For example, 16 ounces of oil to 2 gallons gasoline is a 16:1 ratio (first column). Only the last column on the right yields the proper 50:1 mixture of (approximately) 16 ounces of oil to 6 gallons of gasoline. I've found that the easiest way to remember it is 2.6 ounces of oil to each 1 gallon of gasoline ... for a 50:1 mixture. Then, it's simply a matter of multiplication for a particular number of gallons of gasoline. Where did I get that figure? My Rotax engine manual recommends 2% mixture oil to gas. 1 gallon 128 ounces. 128 x .02 2.56 (rounded to 2.6 ... unless you can figure out how to measure .56 of an ounce :-) I'd rather err on the side of slightly too much oil. I have a chart near my gas cans for the most common can sizes similar to the following: Gas Oil ---- ----- 1 gal 2.6 oz 2 gal 5.2 oz 2.5 gal 6.5 oz 5 gal 13 oz 6 gal 15.6 oz (which is close enough to the 16 ounces in the yellow bottle) Randy Berry Kolb Firestar KXP n.com ________________________________________________________________________________

What number of jet needle are you running? It sounds like you might need to go to a different needle.

Subject: Re: Fun with your 447
I have never worked on a 447 but if it is a dual carb then perhaps you could try swapping the carbs around and see if you still get the same white and carbon combination or if it swaps cylinders too. If it does it is in the carbs. If single carb you have to be getting an air leak in the back cylinder some how even if it was just rebuilt. Try new gaskets on the intake and exhaust manifolds.

Subject: Full swival, steerable tailwheel
Does anyone on the digest have a full swivel, steerable tailwheel that would work on a FireFly by Kolb? Where can one be purchsed or does anyone have a drawning of one? My 447 Rotax has about 190 hours on it. It was cylinder inspected at 175 hours and the walls of the cylinder and the top of the piston looked like new. No carbon build up anywhere. I get 2.5 gallon burn per hour, use Amco middle grade octaine gas with 6.25 gallons of gas mixed with 16 ounces of Pennzoil air cooled engine oil. Two ounces of Marvel Mystery Oil added also. In-flight temps. are cruise EGT 1050 and CHT at 300. Plugs always have the same color when changed, no deposits, always a clean burn. Usually starts with two or three pulls, this morning started with one pull.

I went the same way, but with no weight on the gear, the bar wouldn't go thru, cause the axle holes didn't line up. I had to cut the rod in 1/2, slip one end of each half thru an axle hole, and clamp a straightedge across the inner ends. Double checked it by clamping the center of a straight 2x4 lengthwise against the outside of each wheel, and measuring the distance between the ends, fore and aft. Larry Bourne Palm Springs, Ca.

Just quick reply. Do you have a CPS catalog. They have a table of jets and needle combinations for your altitude and temperature. It sounds to me like you need to change the needle. I would be very careful making internal mods. I'll be going to the airport Saturday and will try to remember to look up the records of what were running in on our 447's. We have them both set up the same but did have to change them from factory settings. Our temps and altitudes are nearly the same. Your a little lower. For some reason the mid range (1/4-3/4) throttle on the FireFly is more sensitive than on our Hawk. If you can get you hands on CPS catalog, read the two sections "Tuning the Bing Carburetor" and "Tuning the Bing Carburetor - Understanding the Mid-Range Circuit". jerryb > >Jerry and Beauford, > >I believe Beauford and I are both having the same problem.

With that in mind, just now I was visiting the friend who's built a Bensen GyroCopter, and powers it with the original McCullough 2 stroke 4 banger.

Puzzled me a bit at 1st, cause the thrust numbers are exactly the same, but I'm now reasoning that if you have to soak up 90 hp with a 72" prop, you'd need more or less pitch to attain different rpm's, but still transmitting 90 hp. Anyone pick holes in this ?? I didn't write down the numbers, but as I recall, at full throttle, Vamoose should run 130 hp or so at around 5000 rpm, which would give about 525 lb of thrust, with tip speeds of around .7 mach.

Date: Sep 01, 2001
I had heard several different opinions on the added weight on our planes due to Poly-Spray. After covering my FireStar with fabric and two coats of Poly-Brush, the first one brushed on and the second coat sprayed on, I weighed the entire thing. All components totaled 135.75 pounds. On all top and vertical surfaces I applied three cross coats of Poly-Spray. On all bottom surfaces, I applied two cross coats of Poly-Spray. After two to three weeks curing time I re-weighed the thing and it now weighs 140.5 pounds for a weight gain of 4.75 pounds. I used about 3.75 gallons of Poly-Spray and one gallon of reducer. These numbers will vary from person to person due to how thick each person applies the coats. Oh well, just a thought.

I think I will put my two cents in here. I know no one will believe it but I have had about the same problems with idling and running and midrange as some have talked about and the cure was weird. I replaced my standard 8 needle with an 11G2. This is a 532 needle. Please do not use the 15K the 503 has for dual carbs. The 11G2 has about the perfect tapper for down here in Alabama. I use the same everywhere and I have been in Tennessee and in Texoma, Texas and lower Florida without any problems at all. My egts run around the 1100 to 1150 mark and the chts about 300 to 335 usually all year long. I never change the notches once they are set, winter or summer. Before anyone po poos me, try it. Just cause it is in the book dont make it right or applicable. Our high set engines get more air than normal and so the leaner needle with the wide taper seems to work really well. Everyone around here seems to think I am nuts but I have used it in two 447s so far and it runs and starts great. One nice thing is it seems to warm up faster on idles and idles better. I also run an after muffler and have tried it on or off on both 447s and the idle is definately better with it on and it is a lot ---- repeat --- a lot quieter. All you have to lose is the cost of a needle. Ted Cowan. By the way, I have a two blade ground adjust IVO and love it. It also runs a lot quieter without the TAPE!! ________________________________________________________________________________

Subject: Re: Engine thrust line?
Larry, I know it looks like the engine is pushing down on the wing, and it is. But the most important thing is for the engine to push you in the direction you wish to go. For me, I want to get the best fuel ecomony at cross country cruise - 63 mph. If your engine is aligned so the thrust is parallel to the bottom of the wing, you will have little better climb but a less efficient cruise. The trick is to find out what the wing angle of attack is during cruise and from this and using an incline meter and a level surface you can set your engine. I flew with the angle of attack meter installed and it indicated six degrees up to the bottom of the wing at 50 mphi which is for my FireFly about 60 mph true. With the plane setting on a level floor, the angle of the wing to the horizontal surface was measured to be eleven degrees. So if I want the engine to push in the direction it was going at cruise I would subtract six from eleven and this would give five degree that the engine should be set to on level ground. I added the half degree for a little lower angle of attack conditions, such as, higher speed cruise, cooler air, and below gross weight. I hope this helps. Jack B.

Hart FF004 Good morning Gang: Experimenting with my Firestar, back in the 80's, I discovered, at times, it would fly faster with less power than WOT. This was caused by soft Lord Mounts allowing the engine to move about dramatically from its static (engine off) position. If I remember correctly, torque caused the engine to shift forward and to the left, placing most of the load on the left front mount. That is, the engine, under power, raised itself in the rear, rolled left and depressed the left front mount. By reducing power I was able to get more airspeed out of it. By playing with the throttle, I could eventually get the Firestar to fly aprx 85 mph with a point ign 447. Course the 447 had been cleaned up and put out an honest 40 hp. For the MK III, I adjust the engine thrust line to be parallel to the bottom of the wing on the ground, eng off. I figure I will get a similar change in engine attitude under power. However, not as dramatic as the old soft Lord Mounts. We have the hardest Lord Mounts available on the MK III's. I experimented a little bit with engine in the stock position and in the raised in the front position before I left for Alaska. Couldn't tell much difference in performance, but decided to stay with the engine raised 5/8" in the front as it has been since very early on in the airplane's life. I used aluminum 3/8" ID bushing stock on top of 2" fender washers on top of the Lord Mounts. The fender washers are 1/4" aircraft fender washers drilled to 3/8". These washers are used on the front two mounts and prevent thrust/torque from depressing the bushings down into the Lord Mounts. Take care, john h (Too wet to fly in Central Alabama today. If I can find time I will try and give you all a quick briefing of my flight to Barrow. I am also trying to find time to get some pics on my web page of the flight.) ________________________________________________________________________________

Subject: Oops - Safety Wire on Matco Brakes
Hello list, Had a little problem on a landing a week ago and wanted to share with the list, just in case others had made the same mistake as I did. I have been enjoying the heck out of my Kolb Mark III. I have been stretching out my xc's a little at a time. I had hoped to make it to London in a few weeks but don't think we will be ready to take that big a bite that soon. Anyway a couple of Wednesday's ago, I flew to Marksville, LA (MKV). Upon landing there was a pull to the right with a slight nose over. I managed to keep it together and no harm done. I attributed the swerve to the right to a slight crosswind and pilot error. Taxied to parking. Met the locals. Enjoyed the compliments on my work on the Mark III. It really feels good to get those compliments on the looks and flying characteristics of my plane. Little did I know that the quality of my work was in question at that very moment. Landed back at my home base (LA46) and heard a thud, thud, thud....... in my right wheel. Upon inspection, found one of the three allen screws that secure the brake disc to the rim had backed out. It was hitting on the wheel brake cylinder with every rotation. OK this is when I find the holes in the disc itself for safety wire of each screw. This was just an oversight on my part. Could have been worse. A nose over or ground loop due to a locked wheel on landing. Anyone have a source for stainless, 10 x 24, 3/4" allen screws (drilled for safety wire)? Can't find any in AS or Wick's. That is what these longer xc's are for. To find those little problems that only show themselves with hours. Please learn from my mistakes. Most of you probably were smart enough to catch this right off the bat. Don't assume that your airworthiness inspector will catch little details like this. Every now and then, a super duper prefilght and inspection is probably warranted as the hours build. Thanks, John Bickham St. Francisville, LA Kolb Mark III - 912 49 hours since May 5 ________________________________________________________________________________

Call George at MATCO if you want drilled socket head screws. Or go to the local fastener shop to purchase and drill your own. I had good luck using safety wire, although it is time consuming everytime you need to pull a wheel. Before I upgraded to the new wheels and brakes I used some bearing locker on the screws. Had no problem with the trying to back out. In fact, it was difficult removing them when the time came.

Subject: bird strike
From: ul15rhb(at)juno.com
Guys, While the list was down I had a bird strike my wing. Here is what I wrote at the time. ......................................... Monday August 13th, 2001: I went flying this morning to Lino Lakes airpark to meet my brother for lunch. After lunch, he was taking digital pictures of me on takeoff. At 200' in a left bank, I saw something big and brown out of the corner of my eye descending off to my left side. I thought it to be a hawk and continued on. As I throttled back to cruise, the windscreen was vibrating a little and noticed I had to hold right rudder which is very unusual. I made it all the way home crossing over the Mississippi River at Anoka, down through Maple Grove and on to Maple Plain, a distance of about 38 miles. I made a good landing and got out of the plane and noticed a 4" long indentation about an inch in depth in the middle of the last rib on top of the wing. I was shocked and was trying to think how this could happen. I then remembered that big brown object I saw as I was climbing out of Lino. The dent was on the straight section of the upper part of the rib. I repaired it by cutting out the dented area and replacing it with a new tube, sliding a 1/4" tube inside. The repaired section will have a .063" wall thickness with the addition of the .035" tube in the center. During the repair I also found a broken 5/16" brace that has been rattling around for quite some time (there was black metal powder on the bottom of the fabric). This brace has no structural integrity for the wing, but is supposed to relieve stress on the bow tip when handling during wing fold. This is the 2nd time it has broken. The original tube was 1/4" and I replaced it with a 5/16" tube 12 years ago. At that time I cut a 2 foot square section out of the bottom of the wing. This time I made a small aluminum bracket and riveted the 5/16" tube to it and the spar. This should last a long time. I'm back in the air now and this bird strike was a very rare event and am happy to report that I could get it fixed so quickly. I never thought birds were a problem with slow flying ultralights, but this has made me think about the potential damage they can do.

I usually look for 60 to 70 mph to droop the flaps. Please take note!!! That is the way I have been doing it for the last 1,600 hours on my MK III. It works and does not seem to have caused any damage. I do not know what the official Kolb Aircraft limits are on flap employment. BTW: I use the flaps every landing unless I am screwing around and experimenting with landing clean, or............I have a lot of turbulence with or without a cross wind. Then I land clean.

Subject: 1/4" brace in wing
From: ul15rhb(at)juno.com
> Ralph and Gang: > > Reference the above mentioned brace. Exactly where is it > connected? From main spar to leading edge tube, on the > outboard end? > > Take care, > > john h John and others, This is the 1/4" brace in the wing (and is the only 1/4" tubing in the wing) that stretches from the rear of the 5" spar to the trailing edge on the bowtip corner where is joins the ailerons. It breaks at the bend where it's riveted to the spar. If it does break it's not that big of a problem if caught early (see below) but when it does, it falls down and rubs on the false rib closest to the spar indicated by a lot of black powder on the bottom of the fabric. If this 1/4" tube was attached to the spar according to the plans, I can almost guarantee it is broken in any Firestar airframe that has 400 hours or more. The fix is to make an aluminum bracket and bend it to the same angle the 1/4" tube was bent and rivet one end to the spar and the other to the 1/4" tube. It would be wise to use 5/16" x .035" if it is replaced. The check to see if it is broken would be to swing the folded wing out and turn it upside down, then find the tube in the corner on top of the wing (now bottom), through the fabric, and see if it will drop through and bang on the fabric near the spar. Another check would be to swing the folded wing out and rest the leading edge on a canoe mount, then wiggle the wing at the bowtip (where it joins the ailerons) back and forth listening for the clanking tube. This 1/4" brace looks like it has two functions. One to relieve stress on the bowtip during wing fold and the other is to help keep the bowtip rigid during flight. If your plane has developed a slight roll tendency since build, this could be the problem, or if your plane had a slight roll tendency and it disappeared without explanation, this could be why. The latter case was the one I had, so when I replaced the brace, the slight roll came back during cruise. The fix for roll tendency is to install an offset drilled universal joint which will raise or lower the trailing edge to correct the roll. I did this today and I will let you guys know how it flies. Thanks John for asking about this and maybe that bird did me a favor. I love helping other Kolb builders out there and this is the purpose of this list.

This to warn all your Firestar drivers that your muffler brackets are going to crack (break). I am on my second Firestar and both have had broken (cracked) muffler brackets. They will crack just next to the head bolt mount and the muffler bolt on the muffler side. So far I have had to make three sets of these brackets. I do not know what the answer to this is, but I just keep close watch on them. These can not be seen on a normal preflight, as they are too high so you must get up on a chair or whatever to see them.

Try this source. AVIATION PRODUCTS 805-646-6042 TAILWHEEL ASSYS You need to find one with a round inside diameter that will fit on the Kolbs tail spring. Check what they have. This is one of the sources the RV builders get there's from. You will also need to watch review CG and the extra weight that far back will make a noticeable difference. There was a post by Jack Hart, on one of his pictures, he has one about shorting the tail spring. May want to review it. Make sure the rudder clears the wheel assembly well went sitting. If there not adequate clearance it can drive the tail wheel into the bottom of the rudder if you do a hard (carrier) landing hitting on the tail wheel. jerryb > >Maby someone can get an answer this time, Second try. > >Does anyone have a source of a tail wheel that is full swivel and >steerable that would work on a Kolb FireFly?? > > >Jimmy Hankinson >Firefly #35, 447 Rotax >Rocky Ford, Georgia 30455 >Southeast, Georgia >JYL -- Airport > > ________________________________________________________________________________

Subject: Mark IIIXtra
Date: Sep 03, 2001
Picked up my aero-yellow powder coated kit #2 at Kolb last Wednesday. I have serial #21 which may be the last of the Mark IIIXtras of the heavier type. As Rody mentioned after OshKosh, the new Xtra has flaperons and other weight reduction changes to get the plane under 500 pounds to qualify as an ultralight trainer. They had the plane loaded in the trailer to take to a fly-in. It has a central stick control that terminates in a U-shape with a control handle over both seats to allow flying from either seat. I talked to Danny Mullins about the change in the position of the front portion of the horizontal stabilizer. Original plans called for the attachment to be at the top of the fuselage tube. The other 20 kit builders (and I) will be receiving revised plans, new L-brackets, rivets, and something to pop into the old holes in the tube. He said it just flies better with this configuration with the tail a bit lower. I don't know if the Classic Mark III had the front of the horizontal stabilizer this high or not. One nice feature of the new kits is packaging of the parts. I got 4 plastic-sectioned boxes with a legend in the lid to identify the parts. It helps Kolb insure that everything is complete and helps the builder with organization and no more searching through zip-lock bags for parts (unless you use a big board to tack on the bags as Big Lar suggested). Someone was assembling a Pelican in the building. Kolb is now a dealer for this plane which is Canadian I believe. Less than 4 weeks until the fly-in. Maybe Kolb will provide name tags for everyone.

Hi Guys, I had posted our FireFly as being for sale and got interest from a person in Florida. He's a long way off and I feel he may be better off trying to find one closer by. Any one have a FireFly for sale in the Florida or South Georgia area. We just had a guy go all the way to WV when he lives within 3 miles from the airport when its based. The next week he saw my post. Let's just say he upset after driving 2400 miles. If you have one please forward it directly to me and I'll forward it to him or send a reply directly to him at "Frank & Margie Clyma" Let's not make this man drive so far to pick one up, there has to be a good one closer to home.

Went from aluminum to steel. Only thing I did was prolong their life a little longer and add more weight to the airplane. SS is one of the least resistant steels to fatigue cracks. I believe the problem stems from hard mounting the brackets to the engine, i.e., the cylinder head, in combination to the huge exhaust system hanging out there a ways on the arm of the brackets. Maybe attachment to the engine cases would be a better alternative for mounting. That is where we mounted them on the 582's, if I remember correctly.

Well only time will tell for sure but the odds are with the VW. This engine just refuses to die. There are VW engines turning close to 300 HP in dune buggies and dragsters. There are thousands of VWs already in air planes and few have had problems if properly set up. I for one have a direct drive 2.2L VW in my kolb MKIII and have had no problems with the engine. On the ground I have to limit the time at high power settings to keep it cool but once I get moving my problems go away. In flight my CHT runs 300-325 degrees on a 90 degree day even at full throttle the temps stay WELL under the recommended 375 degree cruse limit let alone the 420 degree climb limit. My oil temps do climb to the 230 degree limit on a hot day at a high cruse but that's a matter of low air flow over a small oil cooler. Now I do have a thrust problem that I hope will be fixed when the new reduction drive engine arrives (I'm having a real problem waiting). Also I'm not currently getting more than 75 HP out of my engine and I likely will not produce more than 80 HP with the new engine. As for the hair trigger waiting to blow I don't think so. You nay sayers probably don't know the development that has gone into these engines over the last 30 years. There is very little in our engines that is really a VW. Racing and dune buggy usage has improved most everything in these engines. Its really neat to select from the high quality parts available for these engines at really low prices.

I reported this problem to Dennis Souder when my brace cracked after about 40 hours on the mark 2. I sent the cracked part to him for his inspection and what we both concluded was that deburring the holes on that part is especially important. I carefully deburred the holes in the replacement set I fabricated and then polished them a little with a scotchbrite pad. They lasted another 100 hours until I sold the plane and still had not cracked. Good luck. Mark R.

Sorry about the subject not being directly related to flying or building, but there must be many helpful AV8TORS out there still using the Garmin 45. Anyone know how to "safely" disassemble a Garmin receiver, model 45? We have one with a loose antenna connector (BNC type) and are concerned the internal antenna connections will fail soon. It appears we've removed all the screws but can't get the case halves apart, at least not without employing an air hammer or cutting torch. An email to Garmin asking for an exploded view or description of how dismantle it prompted a response to the effect of; we don't provide schematics of our products, but do provide repair for the outdated models. With the relatively low cost of new units it doesn't appear feasible to pay for shipping and repair for an older one, especially when the repair 'should' be rather simplistic, involving tightening a nut on the connector. Looking for anyone who's had a similar problem with this series of Garmin receivers and how they've handled repair.

To achieve the same cruise as the 582 requires 400 rpm above max continuous (4000). Possible factors at work here: 1. Mine is a late version of the Verner and has a 2.0 redrive. Original was 2.2. This may be a factor. Fellow in Florida with 2.2 and Warp drive on Mk-3 reports outstanding performance. 2. Drag. The big hunk of iron obviously has more drag than a 582 installation, but on an already draggy airplane how much can this contribute? 3. Verner performance numbers may be inflated. But, if that is true, how come the climb is so impressive? 4. Powerfin prop airfoil not optimized for Verner curves? The Verner is a very sweet motor. Great sound and smooth running. Smooth throttle response. It virtually sips gas. Will start fuel consumption checks today if Wx cooperates.ntribute you can send e-mail direct and post to the list please.

Subject: Re: Fw: Thrust
Interesting. I assume you are running a three bladed prop. Is it a type F? If it is, it will be the same prop I ordered for my VW. The 2.2 to one reduction would handle the 72" prop better with slightly better thrust. Why did you cut the prop down to 68"? Were you getting a lot of noise or were you having to reduce the pitch down below the props effective pitch range or below flying speed to get your engine RPMs up? My expectation is that with these slow turning props, the speed range that the prop will push the plane to will be more narrow than a smaller high RPM prop with lots of slippage. You should be able to recover some if not all your cruse speed by going to a higher pitch. I would guess there will be a trade off of a lower climb rate. Please keep us informed.

Date: Sep 04, 2001
Hello Listers, I've been lurking on the list for several months now and thought I would introduce myself. My inspiration to hang in there comes from reading UL Flying! magazine and following several lister's (Ben and Will mostly)web sites. Although I didn't realize it at the time, the first UL I ever saw up close (in 1995)was the famous Miss P'fer. It was parked at the airport not too far from where I lived at the time but John was no where to be seen. All I could do was marvel at its beauty and wait until he came back. He never did show up and my wife, who was sitting in the car, was ready to move on. Since that day, I've moved 3 more times (I'm in the USAF) and now find myself back in the Montgomery Alabama area.

Will, I have mixed feelings about you shrinking your images. I live on the end of a 26.4KB connection (out in the boonies in low-tech Indiana) so it can take a while for the pictures to download. However, with the increased resolution, they make great screen backgrounds. Also, I have an internet browser called Opera that lets you zoom the browser window. With the larger pictures (more resolution) I can increase the picture size by 200 to 250% to see details (like on your broken bracket) and still not loose any clarity.

Subject: 5 in. Tubing
Date: Sep 04, 2001
Just wanted to make a couple comments about the 5 in. boom / spar tube that comes up every so often, I believe the tube referred to as Irrigation pipe is 6063-T8 and not T6 , I have a couple 10 ft. lengths and took a sample to work for a simple tensile break test, sample was 5 in. O.D. X .050 in. wall and it broke at between 37,000 and 41,000 PSI, not too bad for water pipe . The cost of this pipe or tube is approx. $5.00 per ft. and it is sold in 20 ft. lengths , Wick's was mentioned as a source , they sell 5 in. X .065 wall for approx. $20.00 per ft. and weight is 30% more also,comes in 12ft. length. Am not an engineer but have always wondered why the Kolb attach point for wing / strut was at the mid point of wing panel and not at 66% as most AC are located, would appear that H section would allow spar to elongate under heavy load , have also thought that H section could be extended to a length of 36 or 40 in. and made into a truss to spread load over larger area. Guess one can"t argue with success but after smashing some of this tube to pieces , it still looks fragile .

John and others, This was one modification that I made to my plane when I built it 14 years ago. I have about an inch and a half more dihedral (2-5/8") in the wings than what Homer had designed into it. I wanted a little more roll stability than a standard Firestar for rough air. It still has great roll control. It feels great having a plane that flies straight and true with the stick centered. Not all homebuilts turn out like this.

Subject: Re: dihedral in wings
Ralph and Gang: Homer's philosophy was to make the wings provide as much lift as possible. Thus, straight or almost straight wings. He tried staight wings, no dihedral, eventually putting the small amount of dihedral in for asthetic purposes. With straight wings, on the ground, the aircraft looked like both wing tips were drooped. Therefore, he added a little dihedral to prevent this impression. His forte was extremely slow flight. Thus the large barn door ailerons and tail surfaces. His idea of an enjoyable flight was a lazy, slow flight, not much above stall speeds. At those speeds the ailerons lose their stiffness and give the Ultrastar and Firestar a rapid roll rate with complete control. He also wanted full roll and pitch control through the stall. The last hour this evening I flew a non-aviator friend around the local area. He weighs 210 lbs. We had 15 gal (90 lbs) fuel on board and my 175 lbs of senior citizen body. About 85F, no wind, and we were off the ground in about half the length of my 750 strip. What a pleasant change from ripping out the bathroom for the last couple weeks. I think I like late afternoon flying better than renovating the bathroom. We checked out stall speeds. Clean aprx 43 mph indicated, 40 deg flaps aprx 38 mph indicated. That puts stalling in ground effect a little over 30 mph. Easing up to the stall, the MK III nibbles at it a little and flies away. However, this is flying straight and level. I think this very, very gentle flight characteristic of Kolb aircraft sometimes misleads folks to think that all stalls and stall warnings will be similar. Not hardly. Especially close to the ground. In that situation, usually in a tight high banked turn at slow speeds, the Kolb aircraft will bite you right in the ass before you realize it. Ask anyone who has survived a Kolb stall/crash. Got to keep your airspeed up to survive near the ground. I try to anyhow. Take care, john h ________________________________________________________________________________

Subject: FW: Thrust
<> Your are right Richard. It is an "F" model prop and I cut it down as I had to pitch it down to 9 degrees to get proper engine rpm. It is currently at 11 degrees and provides the good takeoff and climb performance I mentioned. Increasing pitch starts affecting climb and does very little for cruise. The 582 with the same prop ended up at 13 degrees for good climb and cruise. However, when we run the 582 at 5800 rpm for cruise it is not the old airplane standard of 75% power. It is more like 90% or 58 hp. So, if you are going to cruise your 80 hp four stroker at 75 percent you get 60 hp, not much difference in engine output. When we look at torque curves (manufacturer published) we get the following: The 582 at 3.0 to 1 redrive at 5800 rpm would produce 53 ft. lb. of torque x 3 = 159 ft/lbs. The Verner produces 93 ft. lbs at 3800 cruise x 2.0 = 186 ft/lbs. The question is how can the 582 pull 13 degrees of pitch and the Verner only 11? The Verner dealer, Steve Flynn, says that when they changed to the Warp drive taper tip on the Mk-3 Verner they picked up almost 15 mph in cruise with no change in climb performance. Don't know what their original prop was. Flight test yesterday was aborted due to small leak in fuel shutoff valve.

Just a "back yard" homebuilder and flyer. I believe the reason for increased incidence (angle of attack) is to facilitate take offs and landings. Other than the Ultrastar, Sling Shot, and Kolbra, the remaining Kolb models sit low to the ground in a level position. This set up makes it difficult to rotate on takeoff or flare on landing, preventing stalls close to the ground. The airplane must takeoff and land in a semi-level attitude. In addition, most of the aircraft weight is on the main gear to facilitate ease of ground handling (taxiing). However, this also makes them prone to nose over, especially the MKIII when carrying a passenger. I don't like those characteristics. That is why my MKIII is configured differently: a. More weight on tailwheel and b. Nose of the aircraft much higher in the 3 point stance. The differential between horizontal stab and wing is necessary to fly in a more level attitude. At lower speeds the tail does not drop excessively to increase angle of attack for necessary lift. On the other hand, the Sling Shot, when brought back close to the stall is in an exagerated tail low attitude because there is much less built in incidence in the wings. I have no experience flying any fixed wing with more dihedral than the Kolbs. Take care, john h ________________________________________________________________________________

It is my understanding that dihedral has the three following effects, if it is pronounced. 1. Adds Stability 2. Loss of Lift. 3. Loss of Speed. I doubt that the small amount of dihedral in the Kolb contributes to a lowering of it's speed, but may contribute to 1, maybe 2 mph? Here I thought there was no dihedral in the Kolbs at all and thats why they have 10 mph plus over similar designs. B.J. Moore, P.E.

Takes twisting power to turn that prop and the 582 is twisting it with more pitch. I have no experience with the Type F prop. I fly a fast taper Warp Drive. Tested it at 72" and 70". Get very similar performance from both diamters. About one degree pitch difference to get the same figures. Here is what Verner says about its engine: ********************************************* 80 BHP (58 kW) @ 5,000 rpm (5 minutes maximum!) 70 BHP (52 kW) @ 4,000 rpm ********************************************* If you are pitched to turn 5,000 rpm at takeoff (good for 5 min mx) for good climb performance, when you come back to 4,000 rpm (max continuous), you have lost your cruise. The way I set up the 912 80 hp for best overall climb and cruise performance: *************************************************** 81 hp at 5,800 rpm (5 min max) 79 hp at 5,500 rpm (max continuous) *************************************************** Since I do not have an inflight adjustable prop, I use 5,500 to 5,600 for my redline. I pitch the prop so the engine will turn 5,500 to 5,600 rpm, WOT, straight and level flight. This gives me best climb and cruise performance. 75% power is attained at 5,000 rpm. The 912S figures look like this: ********************************************* 100 hp at 5,800 rpm (max 5 min) 95 hp at 5,500 rpm (max continuous) ********************************************* 75% power is attained at 5,000 rpm Bill, what you may have to do is give up a little climb performance and pitch the prop to give you 4,000 rpm WOT straight and level. Even if you go with a Warp Drive fast taper prop, you will still have to use 4,000 rpm as redline WOT straight and level in order to get the best of both climb and cruise with a ground adjustable prop. john h ________________________________________________________________________________

Subject: Re: FW: Thrust
This just doesn't sound right. Does the Verner weigh a lot more than the 582 or has anything changed with your air speed indicator. If none of this has changed then about the only thing it could be is the torque figures you have been given are inaccurate. This prop selection thing is kind of a black science. My guess would be that the tapered tip warp drive requires less torque to turn the same RPMs and allows the Verner to turn a larger 72" prop within its effective pitch range which would give more thrust and speed at cruse. If my limited knowledge (assumptions) are correct the app.1900 RPMs at cruse are about right for a 72" prop at MKIII speeds. The testing that my reduction drive manufacture and also Great Plains VW indicate static thrusts of around 250lbs. direct drive 3600RPM with a 60" prop, 500lbs. with a 1.6 to one reduction turning a 72' prop, and 600lbs. thrust with a 2 to one reduction turning a 84" prop. This seems to tell me that the larger prop you can turn the more thrust you get for your HP. I don't know the exact props that were used for these tests but the 84" is a two bladed wood prop. I would go with Verener's recommendations for props and take advantage of their testing. If you want to stay with the Power Fin maybe a smaller profile 72" would work better??? My $.01 cent worth Rick Neilsen VW powered MKIII >>> WGeorge737(at)aol.com 09/05/01 10:24AM >>> Your are right Richard. It is an "F" model prop and I cut it down as I had to pitch it down to 9 degrees to get proper engine rpm. It is currently at 11 degrees and provides the good takeoff and climb performance I mentioned. Increasing pitch starts affecting climb and does very little for cruise. The 582 with the same prop ended up at 13 degrees for good climb and cruise. However, when we run the 582 at 5800 rpm for cruise it is not the old airplane standard of 75% power. It is more like 90% or 58 hp. So, if you are going to cruise your 80 hp four stroker at 75 percent you get 60 hp, not much difference in engine output. When we look at torque curves (manufacturer published) we get the following: The 582 at 3.0 to 1 redrive at 5800 rpm would produce 53 ft. lb. of torque x 3 = 159 ft/lbs. The Verner produces 93 ft. lbs at 3800 cruise x 2.0 = 186 ft/lbs. The question is how can the 582 pull 13 degrees of pitch and the Verner only 11? The Verner dealer, Steve Flynn, says that when they changed to the Warp drive taper tip on the Mk-3 Verner they picked up almost 15 mph in cruise with no change in climb performance. Don't know what their original prop was. Flight test yesterday was aborted due to small leak in fuel shutoff valve.

A 900 pound Mk-3 with a 582 is the same as a 900 pound Mk-3 with the Verner. Speeds are GPS verified and flight attitude is also a good barometer of cruise performance. Stall speed is the major reference. If your cruise speed is only a few knots above stall at published cruise rpm there is a problem.

Pitched at 4900 rpm climb, reduced 450 prop rpm to get back down to max continuous cruise at 4000, again, is like trying for Ferrari cruise with Farmall gearing. I firmly believe if you try to fly this airplane and engine with a 70" fast taper Warp Drive, set up to climb ate 4900 rpm, you will be no better off than you are now. In order to get the best of both climb and cruise you must compromise with a ground adjustable prop, i.e., you got to pitch for 4000 rpm max continuous power and loose a little climb, or pitch higher and loose a lot of cruise. You can not have both when the prop rpm spread is 500 rpm from 5000 to 4000 eng rpm. Take care, john h ________________________________________________________________________________

I had placed the prop in the Y position and proceded to fold the right wing and then noticed that the botton blade was not centered over the boom tube. As i grabed the prop to move it the prop kicked forward and sliced a nice 8 inch hole in the bottom of the right wing, aparently i had one piston on top dead center and didn't realize it . When i grab the prop and started to move it the compression kicked the prop out of my hand slicing the wing . I now place a large cardboard tube over the bottom blade when folding the wings for protection as i think someone could just as easily pull on the prop and do the same thing.

And I really mean it. I sell little model gliders that fly. I sell really CHEAP model gliders that fly. So cheap as a matter of fact, that they only cost about $.25 each. One of the reasons that they are so cheap is that they are made of polystyene foam, and consist of only 4 parts, a weight for the nose, a stamped out fuselage, wing, and horizontal stabilizer. All the three stamped parts are flat. That's why they are so CHEAP! Slide em all together and they fly, and with quite good stability, surprisingly enough. When viewed from the side it is easy to see the high angle of incidence between the wing and the horizontal stabilizer. There is NO dihedral. And the plane is very stable in the air. Sometimes the wings have accidental anhedral and the darn thing still flys good. Blows me away as I have made little gliders since I was 3, and learned then that wings and horizontal stabs usually were pretty darn close....but I never really understood what was going on, I actually thought that the horizontal stab was another flying surface!! But how could it be if the leading edge is pointing .....down. Well, that's enough for now....see if someone else is challenged by such wild inferences....which I didn't even state, ie, that the dihedral of a plane, which is only there for stability, can be replaced by a horizontal stabilizer with the leading edge canted down.....just like the Kolb models that JH described, one of which is, the Firestar, that I have.

Clay, If your ailerons are installed correctly they will NOT fold as the manual says. I visited with Ray about this problem, he has fabricated a bracket that inserts into the backside of the aileron counter balance tube at the tip of the wing. This will keep the ailerons in a normal or flying position while the wings are folded. I did take a picture of the bracket but unfortunately I do not have the disk with me right now.

I would not have thought of this but now I will take the proper precautions. Ron Payne Ron & Mary and listers, Watch out for the sharp trailing edges of the Ivo blades when folding the wings. I had a bad experience with mine when folding the wings . I had placed the prop in the Y position and proceded to fold the right wing and then noticed that the botton blade was not centered over the boom tube. As i grabed the prop to move it the prop kicked forward and sliced a nice 8 inch hole in the bottom of the right wing, aparently i had one piston on top dead center and didn't realize it . When i grab the prop and started to move it the compression kicked the prop out of my hand slicing the wing . I now place a large cardboard tube over the bottom blade when folding the wings for protection as i think someone could just as easily pull on the prop and do the same thing.

Page 20 of the supplemental drawing book, drawing revision 3-96, shows 8mm bolts 20mm long holding the muffler bracket to the case. No locking washer is shown.

Subject: Re: aileron deflection
I'm not sure you really got a answer to why they recommend that the aileron should fold within 6". The concern is that when you fold the wing up against the other wing for storage and/or travel you will need the to have the ailerons fold out of the way to get both wings connected to the tail fold fitting without bending anything. If you don't plan to fold the wings there is no problem. Some people have figured a way to keep the ailerons out strait when folding the wings so this is also no problem. Hope this helps. Rick Neilsen VW powered MKIII >>> cstuart(at)searnet.com 09/06/01 09:52PM >>> I have temporarily installed the aileron and flap on one wing of my Mark IIIXtra. The manual says to verify 30-35 degrees upward deflection. I have about 70 degrees upward. It then says that "the ailerons must be able to fold downward to within 6" or less of the bottom of the wing during wing folding". I don't know what they mean by this. I have around 120 degrees deflection downward, but it would take around160 degrees to get the trailing edge of the aileron within 6" of the bottom of the wing. Please clarify, and do I have reason for concern? Thanks, Clay Stuart Danville KY ________________________________________________________________________________

Subject: Re: stability
Date: Sep 07, 2001
dihedral and horizontal stabilizer incidence are completely unrelated to each other and have very different effects on flying characteristics of a plane. stabilizer incidence is set as needed to hold the nose up. On kolbs they are set at a fairly steep angle because they are low aspect ratio delta wings that have a low lift curve slope and a high stall aoa. they make little lift per degree aoa and make maximum lift at a high aoa. this only effects pitch stability. dihedral primarily effects roll stability, with very little effect on pitch stability. Kolbs are about neutral in roll stability, with more dihedral they can be made as stable in roll as you like. will it cost some lift, yah, but unless you went above 10 degrees you probably wouldn't notice. cos(10)=.98 so you lose around 2 percent lift at ten degrees, not enough to worry about. what you do lose is roll control. the extra stability keeps you from rolling as fast. you are also rolled around more due to gusts of wind, with less roll control available to catch yourself. ________________________________________________________________________________

Subject: Re: Heel Brakes
I would try to avoid using the Azusa style drum brakes with the internal brake mechanism. Instead use the external band brake instead. I assume you have the steel rim wheel barrow style wheels. The tires are rims are fine but the China bearings that they come with suck. Wheel barrows were never intended to go 50 MPH. They help contribute to the brakes erratic grabbing when using the internal brake set mentioned above. Replace them with some quality bearings - USA/Japan, no China - shouldn't cost more than $5 each, if so let me know and I'll get them for you. (TIP: Drill the holes in wheel for mounting the drum one at a time. Means a lot of assembly and disassembly but it produces better centering alignment.) FYI: Good quality wheel bearings for Kolb steel wheels - P/N 499502H These are a little different - these have something like a snap ring around one side of them which acts like the retainer flange on the ones being replaced - good bearing will help reduce random brake grabbing - cost should be less than $5 each or $20 for two wheels. Source - most any bearing sales. Anybody got anything better bears with the flange please let me know. The external band brake system still uses the Azusa drum but instead of the internal brake mechanism it uses a band about the width of the depth of the drum. See Web Page URL below. Azusa has a problem with their stamp die press operation which results in the drums having high points. The band goes around the outside of the drum and is mounted at one point. This allows the band to float so there is less grabbing with this configuration. This band solution should also save weight. See the URL below for an illustration. A bracket with an brake cable adjuster maybe mounted to position the cable and allow fine adjustment. It can also provide the band mounting stud for securing the band. The brake cable goes thru the secured end of the band and fastens to the floating end. When you apply the brakes it pulls the cable and squeezes the band around the drum. They work better than the internal shoe/spring mechanism and should be lighter. If you have a Northern Hydraulic catalog or visit their web site. They sell the drums and bands, cables, etc. Also look under Karts as in go-karts on google.com. See URL's below: Band: http://www.azusaeng.com/brakes/bandbrk.html Internal: http://www.azusaeng.com/brakes/4brk.html Hope this is useful, jerryb > >Hi Mike and all > Make the pedals from locally acquired steel---take your hack saw to > the salvage yard and you will find something that is suitable.

Lanny, Yes, we have strobes and we fly with our wingtip lights while on day visual low-level. Sometimes, we will put on our landing lights out, however most C-130's have a 165KIAS limitation on the landing lights, the model H3 that I fly has a 250KIAS restriction. The Kolbs have excellent visibility from the 9 to 3 o'clock position and you will usually see a C-130 sized airplane in plenty of time to get out of our way if approached from that direction, we will probably see you from almost any angle exept coming directly at us or away from us, what is scary is to think about fighter type aircraft at low-altitude, they may not see you in time to avoid and you probably won't see them in time to avoid, however outside of Restricted, Warning areas and MOA's these aircraft are usually on the VR IR routes marked on sectionals. I'll ask some of my fast mover buddies about their training routes and share with the list. Brett Williams, Firefly Brett, During day operations, when flying low do you fly with recognition or landing lights on? -- Kolb-List message posted by: "williams brett" Lanny, I am a proud owner of a Firefly and a C-130 pilot, the aircraft you saw may have been a C-130.

Try Microsoft Front Page 2000. I use it for both of my webpages, and had to recently switch providers, so I had to download the entire website. I also downloaded my RV website to a CD rom for my DAR to look at when the RV was inspected. I used Front Page for this, and it worked fine.

Subject: Re: 532
I have used a 532 on my MKIII for several hundred hours with good results. It is bulletproof (so far!) but has had a few problems. It had a small leak in the original case joint by the magneto housing. It was sucking air/blowing oil into the magneto cavity. This was from the factory. A CPS crankcase pressure tester found it. The original point ignition caused some problems on the way to Oshkosh in 98, was replaced with a CDI magneto from Airscrew Performance. Excellent reliability since then, starts easy. The 532 has a tighter torque band than the 582. I had poor luck with an IVO 64" three blade prop, the three blade loads up the torque curve quicker than the two blade, and the 532 has less mid range torque than the 582. I am currently using an IVO 66" two blade with very good results. The engine will probably have some pipey places where it will not stay. It will either get on the pipe or fall off the pipe and have a band about 400 rpm wide where it will not stay. This is a kind of minor nuisance, and is not worth spending the price of a new engine to cure. Depending on the prop and how you pitch it, and also on your exhaust pipe, is where that band is. My MKIII has been modified somewhat for less drag and better lift, and will fly at 58 MPH with fuel burn of less than 3 gph solo. With two adults and 75 MPH, it burns about 4.5 gph. Top end is just under 90. You do have to mix the oil and gas, but that is not a big deal once you get used to it. I carry around a big funnel that fits my gas tank opening, and allows me to dribble the oil in while pumping avgas in at the same time, mixes it pretty good that way. If you can afford it, a new blue head 582 is the way to go, but if not, I think a good 532 might be more reliable than the early 582's. I have heard that between those two choices, the 532 has a better crank. But that is hearsay. I am satisfied that a 532 can be good value for the money, assuming it is in good shape. There are some pictures of it on my web page, http://www.bcchapel.org/pages/0003/kolb.htm Richard Pike MKIII N420P (420ldPoops) > >Has anybody had experience with the rotax 532?

Hope these help someone.............I'm starting to run out of inspiration..........not too sure how many more of these you'll see. Updated engine pics should be along in a couple or 3 weeks, and from there we'll have to see. To you-all who use MicroSoft Front Page professionally............me hats off to ye ! ! !

Will and Group, I have recently moved my web page to a free server. Also, it came down to money. I had changes ISP's, after moving to the Upper Michigan, and kept my old ISP just to keep my web page free of advertising. But $18 per month is too much to keep advertising off my web page, so now it is with the free web provider, 0catch. Yes, there is really a catch. They put advertising at the bottom. But I prefer that to the top. One can make each page large enough so that the advertising is hidden, unless scrolled. Those that want to keep a web page for free and still have control of it, may want to consider 0catch. Take a look at my Firestar II page on 0catch: http://jrjung.0catch.com/Firestar.html John Jung ________________________________________________________________________________
