    Subject: Dirt in the exhaust
    I was finally able to get the rest of the dope on the Ultrastar and test-run the overhauled engine. A slight problem arose....Apparently when the engine was detached from the airframe in the cornfield some dirt made its way into the exhaust. Before installing the exhaust after the overhaul I blew compressed air into both openings and did not notice any thing unusual...no rattling noises ...But upon starting after 5 or 6 pulls on the rope, a bunch of small pieces of dirt and corn stalk blew out....My question is this...when you pull a 2 stroke through with the rope and it does not fire, what are the chances of the dirt back sucking into the cylinders. I know soon as is starts the flow ejects anything in the exhaust but is there a chance it may have got into the cylinders....2 strokes are funny ducks ! Waddling around Ed in Western NY ........... had to drop the "Know it All title"

    --> Kolb-List message posted by: Richard Pike <richard@bcchapel.org> Have a 582 and B box, 68" Ivo two blade, so standing at the tail and looking forward, the prop turns clockwise. Thus you have a swirl of air that also turns clockwise, ahead of the prop as well as behind it. Which plasters gnats appropriate to that swirl ahead of the prop (about 18" max) as well as behind it, which means it would also be pushing the right flap down, and the left flap up. At least to the extent that slop in the mechanism allows, which shouldn't be all that much.

I know soon as is starts the flow ejects anything in the exhaust but is there a chance it may have got into the cylinders....2 strokes are funny ducks ! Waddling around Ed in Western NY ........... had to drop the "Know it All title" Funny Duck: Can't say for "certain" whether it will suck dirt out of the exhaust or not, but there is a darn good chance it will. Some years ago, 1989, on a return flight from River Ranch, FL, 447 powered Firestar, wrist pin needle bearing came apart in one cylinder. When I pulled the cylinders off, there were needles stuck in the top of both pistons, although the 447 has two seperate crankcases. Undoubtedly, the needles from one cylinder were blown out the bad cylinder and into the good cylinder. NOTE: This engine started coming apart while at the flyin, yet made it all the way from Central Florida back to Titus, Alabama. Very fortunate, i.e., lucky as Hell. john h (chicken hawk) mkIII PS: Did someone come up with SN: M3-001, the first customer built MKIII? I think it was Rudy Doctor. I remember seeing his kit, ready for shipment, when I arrived at the Kolb Company 1 Feb 1991.

    Subject: Twin Engine Firestar 2
    --> Kolb-List message posted by: "Gherkins Tim-rp3420" <rp3420@freescale.com> Dave, Thanks for posting your report. I found it very interesting and appreciate your pioneering resourcefulness. Tim Gherkins FSII -----Original Message----- Sent: Monday, June 26, 2006 10:40 PM --> Kolb-List message posted by: "Dave Bigelow" <up_country@hotmail.com> Several months back, I posted my intention to install two Hirth F-33 engines on my Firestar 2. The design goal was to end up with an aircraft that could at least maintain altitude on one engine and get to a landing spot if one of the engines failed. The main issues I anticipated were vibration and the possible interaction of the overlapped propellers. The engines were mounted on two struts that were secured to a flat plate that was mounted on the original Lord engine mounts. In turn, the engines were flat plate mounted on their own set of mounts. The right engine uses a prop extender to put the 53 inch Powerfin two blade prop 4 inches behind the left engine prop and allow the overlap. Each engine is mounted 16 inches from the aircraft center line, and each propeller clears the aileron on its side by several inches. The whole installation including the mounting system (excluding battery) weighs almost exactly the same as the Rotax 503. The interaction of the two propellers crossing each other in opposite directions at the overlap was pretty much a gamble. I couldnt find any information whether or not it would work. In the early 80s, I had the chance to do some thrust tests on the twin engine setup of the Para Plane powered parachute. The Para Plane installation was very well designed with two small single cylinder (Solo, if I remember correctly) engines mounted on both sides of a central set of concentric prop shafts. The engines were connected to each shaft with a belt drive, and the props counter-rotated several inches apart. We wanted to find out if the two counter-rotating props would affect each other at various RPMs of the two engines. Interestingly enough, there was no measurable affect. With both engines running at full RPM, the thrust (150 lb) was twice that of when one engine (75 lb) was run alone. With that knowledge in my pocket, I figured overlapping props crossing in op! posite directions would probably not interact appreciably. It took several months of part time work to get the mounts set up and the throttles/choke, fuel system, and electrical system set up. When all that was complete, I tied the Firestar securely, and started and broke in the engines. I had some jetting issues because of being at 5,000 feet density altitude. Matt Dandar, the owner of Recreational Power Engineering (where I purchased the F-33s) gave me good technical support, and I got the engines running quite well. With a spring scale tied to the tail wheel area, each engine measured about 150 lbs of static thrust when run alone. The vibration level was about what you would expect from a single cylinder engine not unreasonable at all. However, when both engines were run together at high RPM, the thrust was only a little over 200 pounds, and the vibration level was high. It appeared that the area where the props overlapped and crossed was too turbulent for the props to work efficiently. I had to wait several weeks for the local winds to drop below 10 mph, but finally had several days with light winds. I trailered the Firestar to the Waimea Airport, which has almost a mile of paved runway. My grass strip at home is only 700 feet long, and is not ideal for testing a modification of this magnitude. Takeoff confirmed the static thrust test info. The thrust was not nearly equal to the Rotax 503, and it should have been greater. I climbed to a couple of thousand feet above the airport and alternately put one engine to idle, and the other to full throttle. The yaw was easily controlled with rudder and I could just maintain level flight. Vibration was about the same as with the Rotax 503. With both engines anywhere above 4,500 RPM, the vibration was severe enough that eventually something on the plane would fail. I did a touch and go, and a full stop and called it a day. The experiment was a failure, and I really dont see that there is much I can do to fix it. I think it would work if the engines could be moved far enough apart to eliminate the propeller overlap, but that would require bigger struts (more weight and drag). Also, the aileron gap would have to be extended (shorter ailerons) to provide sufficient clearance for the props. I hate to post the details of a failed experiment for the world to pick apart, but believe it is good to get the info in the archives in case someone else in the future has the same idea. I think it could be made to work with a concentric shaft counter-rotating setup like the Para Plane, but I dont have the machine shop resources available to build it. Guess Ill remount the Rotax 503 and go fly. Mine has never missed a beat, and hopefully will continue in that mode. In the meantime, Im looking at the HKS 700E. As a footnote, the Hirth F-33 engines are beautifully engineered packages, and Im in no way being critical of them. They are good engines, and Matt Dandar of RPE backs up and supports his product. They would be my first choice as a light weight compact package for a single place trike, powered parachute, or other Part 103 legal ultralight. -------- Dave Bigelow Kamuela, Hawaii FS2, Rotax 503 DCDI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=43287#43287 Attachments: http://forums.matronics.com//files/twin_hirth_f_33_firestar08_142.jpg http://forums.matronics.com//files/twin_hirth_f_33_firestar07_214.jpg

    Subject: Hope I'm not making a big mistake....
    --> Kolb-List message posted by: "jimhefner" <hefner_jim@msn.com> For those of you that know me well, you know how much I enjoy low and slow flying and photography in my little yellow Firefly. Well, believe it or not, I am in the process of buying 1/2 of a Cessna 150 and am starting work on my GA ticket. I have a new wife and daughter that I brought to the US from China 3 months ago. When we were in MV in May, Dave Rains took us all up in his C-175 and we had a great time. I now find I don't go up to the airport much and when I do go up there I don't fly very far. I don't see any long trips with plane and trailer like last year in the future, so I've decided to go the GA route and later I can fall back to the Sport Pilot rating if desired. I think I will learn alot getting my GA ticket, which will be inexpensive since all the lessons are part of the deal on the plane, making it too good a deal to pass up.... the plane is also 10 min's from my house, compared to 50 min's to the airport where I keep the FF. After one flight in the 150, I can see I have a lot of adjustments to make and get used to. The most striking difference is the glide slope approaching the airstrip! [Shocked] Eventually I will probably sell the Firefly and trailer, but am in no hurry on that until I'm sure I'm doing the right thing.

Some people would say that you can't be any more crazy than you already are. Needs change. Not many people stick with the same "stuff" forever. The guy that I bought my Original FS from was selling it because he didn't like leaving his wife sitting at the airport while he went out and bored holes. My only comment would be to remind you that there is a world of difference in the payload of a C175 and C150. Make sure that a C150 will serve your "new" needs. Unless the 3 of you are all below average in weight, you could be out of, or at least, marginally close to the edge of the envelope of a C150. Particularly if you have to deal with density altitude. Like they say..... advice and comments.... get what you paid for it. -------- George Alexander http://gtalexander.home.att.net Read this topic online here: http://forums.matronics.com/viewtopic.php?p=43375#43375

The tuned exhaust isn't even working at that point. I would suspect the dirt got sucked in the intake and was in the crankcase or transfer port channels from the crash.

    --> Kolb-List message posted by: "jimhefner" <hefner_jim@msn.com> Thanks George. Yeah, the 150 is definitely not a 175 and is just a 2 seater, so I am not buying it, intending to fly all of us together. We're all on the small side, so any two of us won't be pushing the limits on the 150 much, but we do get lots of high DA in AZ in midday. I prefer to fly mornings, so hopefully that will not be much of a problem. I'm looking at this as a good way to get started in GA for little investment and a few years later I may decide to sell my 1/2 interest when it no longer fits our needs. The price and prime location should make it an easy sell later on. It's a real solid little airplane. -------- Jim Hefner Tucson, AZ Firefly #022 447, 2 blade IVO, BRS-750 Do Not Archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=43385#43385 Attachments: http://forums.matronics.com//files/062306_c_150_002_small_889.jpg

    --> Kolb-List message posted by: "JetPilot" <orcabonita@hotmail.com> I would get a Kolb MK-III Xtra instead of a 150. The visibility of the 150 sucks compared to the Kolb, and the expenses of general aviation will add much faster than you think. You will be pretty much stuck inside a aluminum shell with small portholes to look out of, and confined to longer well developed runways. I have owned 2 Cessna 150's and have no desire to own another one. I also have a wife that likes to fly and I would not even consider a single seat plane, thats why I got the MK-III. It carrys two people without all the disadvantages and drawbacks of the Cessna 150... JettPilot -------- &quot;NO FEAR&quot; - If you have no fear you did not go as fast as you could have !!!

The study indicated that water injection did influence fuel flow and help the engine to run more efficiently. How it was done and the results can be seen at: http://www.thirdshift.com/jack/firefly/firefly58c.html I did not fly with this system, and I have not tried it on the Victor 1+. The jump to Factory Direct no longer works, but the same info can be seen at: http://www.msdpowersports.com/ Look in their catalog and look at page 19. In their case they are automatically changing water flow rate to meet changing engine rpm. This is not necessary for flying because most of the time the engine is at a constant throttle position, so it is possible to manually control the water flow rate to match the engine rpm. This makes for a much simpler system, made up of a water storage vessel, a pressure source and the calibrated needle valve to control the water flow. Jack B. Hart FF004 Winchester, IN

Well, believe it or not, I am in the process of buying 1/2 of a Cessna 150 and am starting work on my GA ticket. I have a new wife and daughter that I brought to the US from China 3 months ago. When we were in MV in May, Dave Rains took us all up in his C-175 and we had a great time. I now find I don't go up to the airport much and when I do go up there I don't fly very far. I don't see any long trips with plane and trailer like last year in the future, so I've decided to go the GA route and later I can fall back to the Sport Pilot rating if desired. I think I will learn alot getting my GA ticket, which will be inexpensive since all the lessons are part of the deal on the plane, making it too good a deal to pass up.... the plane is also 10 min's from my house, compared to 50 min's to the airport where I keep the FF. After one flight in the 150, I can see I have a lot of adjustments to make and get used to. The most striking difference is the glide slope approaching the airstrip! [Shocked] Eventually I will probably sell the Firefly and trailer, but am in no hurry on that until I'm sure I'm doing the right thing.

    --> Kolb-List message posted by: "Guillermo Uribe" <WillUribe@aol.com> Hi Jim, After building my FireStar II I stopped flying my Cessna 172 after owning it for almost 20 years. I then eventually sold it to Dave Rains. A Kolb is so much more fun to fly then a Cessna. Last Sunday Dave and I were landing at Dell City in the 175 when the case on one of the mags broke. We had to leave the Cessna there until he can get a replacement. To replace the part it is going to cost him about $600. Can you imagine how much it will cost if you bent your Cessna gear in an off airport landing? Dave now has the 172 up for sell so we can build a Kolbra. I would buy a MK-III then a C-150.

    --> Kolb-List message posted by: "David Key" <dhkey@msn.com> Jim, I did something similar. I drove an hour to fly my Kolb Mark III with a 582 every weekend, then got my pilots license, then sold my Mark III, flew various airplanes 150, Katana, 172, 182, 182 turbo RG. Then spent a bunch more money getting my instrument rating. Then it occured to me watching instruments, making calculations, and reading approach plates wasn't why I started flying and wasn't what I enjoyed about it. I cant imagine what you found fun about a 175 compared to a Kolb. A Kolb isn't a family plane and it's not a plane you can load up with your luggage and go skiing. But it does fun really well. I'm back to Kolbs because I realized I don't want to travel, I just want to fly. In GA flying if you ever notice you never go to the airport unless you want to go somewhere then you'll know it's time to come back to a Kolb. I bought my a house on an airport and I'm building a Mark III Xtra with a 912. I haven't flown GA in 5 months. You're not making a mistake, just a curve in your jorney. See you back in five years. Don't do the instrument training!! They estimate it low so you'll do it, it ends up being really expensive.

    --> Kolb-List message posted by: <jeepacro@cox.net> YES! You are crazy but GO FOR IT! I can tell you that I started flying in 1975 and in that time I wonted more. I had several airplanes, and even a glider and still wonted more. So I got a pitt's and did the acrobatic competitions, won a few and wonted more so then I started doing air shows with the smoke in front of crowds and peeked out as far as I'm concerned. There was nothing better than that! I loved every day of it and still do. But then I couldnt justify the cost of fuel burn, hanger,insurance,etc. So I found myself looking to get back into flying stick and rudder seat of you're pant flying FOR PENNY"S ON THE THOUSANDS and I found myself right back into ultraLIGHT. I picked the Firefly so that I don't have to jump through anymore FAA hoops. I can fold the wing's put it into my garage (no hanger) badabig. So I just wonted to tell you my story so that you can apply or compare to you're own someday. And to tell you not to sell you're Firefly because you might do the same circle I did. -- Rob. ---- jimhefner <hefner_jim@msn.com> wrote: > --> Kolb-List message posted by: "jimhefner" <hefner_jim@msn.com> > > For those of you that know me well, you know how much I enjoy low and slow flying and photography in my little yellow Firefly. Well, believe it or not, I am in the process of buying 1/2 of a Cessna 150 and am starting work on my GA ticket. I have a new wife and daughter that I brought to the US from China 3 months ago. When we were in MV in May, Dave Rains took us all up in his C-175 and we had a great time. I now find I don't go up to the airport much and when I do go up there I don't fly very far. I don't see any long trips with plane and trailer like last year in the future, so I've decided to go the GA route and later I can fall back to the Sport Pilot rating if desired. I think I will learn alot getting my GA ticket, which will be inexpensive since all the lessons are part of the deal on the plane, making it too good a deal to pass up.... the plane is also 10 min's from my house, compared to 50 min's to the airport where I keep the FF. > > After one flight in the 150, I can see I have a lot of adjustments to make and get used to.

    Subject: Re: MkIII, suzuki G10
    I am also going to power my M3X with a Suzuki, its a 16 valve DOHC. I have been told various values for the HP from 105 to 120 hp. I am not sure what it will end up being. I am pretty deep into it right now. The good thing is that I can choose just exactly how I want it built. So far I am under 1K including the engine core and accessories. I am sure that will change as the reduction drive alone will run about 1.7K So far so good. If I will convert another later I'll be able to do it very quickly. Its a great motor I am more impressed with it all the time. I was over at the engine shop today and the fellow there said it looks good as new. The pistons that I was planning on replacing after cleaning look as though they just came out of the wrapping paper. So far this little used engine is just fantastic in terms of its durability. It did look like hell from the outside when I first got it. They build them good. I will need to modify the cage on the Kolb and that's for sure. The oil sump needs to sit right where that engine mount tube is at. My solution is two parallel tubes cradling the motor in between. I still don't know why the factory didn't do it that way to begin with. Surely by now they need to consider that due to the tremendous cost of the Rotax 912 very few will be able to afford it. You can buy an entire Suzuki automobile for the cost of one Rot 912, it can't be that expensive to produce. Anyway the Suzuki conversion looks like a better deal all around. I would if I were you get the Suzuki 1.3 16V Sohc, it has a bit less Hp but its usually less expensive and much more abundant.

    Subject: Re: Hope I'm not making a big mistake....
    --> Kolb-List message posted by: "jimhefner" <hefner_jim@msn.com> Thanks for all the replies and encouragement. I like to think this is just a detour in my flying journey. I know a C-150 is not a Kolb, but this deal presented itself and is too good to pass up. It is based in La Cholla airpark where lots of folks have hangars at their houses and is very hard to get in unless you own million dollar property there... must be nice! The co-owner flies a 300hp Maule, so the 150 doesn't fly much. He recently sold half interest in a beautiful Piper Arrow that is also parked in the hangar with the Maule. The owner is very resourceful and can get stuff fixed for minimal cost, so I'm hoping it will work out well and cost cost me an arm and a leg over the next few years. After that we'll see what the future holds.... maybe a 2 place Kolb, we'll see. I know my 1 seat flying days are numbered so it's time to take the next step and there aren't any great deals like this one around here on a 2 place Kolb. -------- Jim Hefner Tucson, AZ Firefly #022 447, 2 blade IVO, BRS-750 Do Not Archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=43513#43513
