From: "Thom Riddle" Slingshot with Jabiru 2200A 80hp engine. The max rpm achievable in S&L flight with the current prop is 3168 though the redline is 3300 where the max hp of 80 is achieved. These numbers were with the big 800x6 tires and taken at about 1,500' density altitude. Numbers are in attached image. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 I am always doing that which I can not do, in order that I may learn how to do it. - Pablo Picasso Read this topic online here: http://forums.matronics.com/viewtopic.php?p=299706#299706 Attachments: http://forums.matronics.com//files/n64086_numbers_230.jpg ________________________________ Message 3 _____________________________________ Time: 04:15:08 AM PST US From: Dana Hague Subject: Re: Kolb-List: Re: Cuyuna engine failure At 12:11 AM 6/2/2010, Mrikio wrote: >My cylinder base gasket has been leaking a little,takes a few hours to get >some residue around the flange.

That would explain the hot cylinder, and in the worse case could cause a seizure. Cuyuna base bolts tend to loosen, and unfortunately the Kolb mount design makes it impossible to get at them. You need to remove the engine mount bolt (I use straps to keep it more or less in place) and retorque the cylinder base bolts. The power loss may be a different issue, though. It sounds like carb ice, and has happened to me, too, but on another occasion I experienced a similar power loss but quicker. I never was 100% certain, but I believe it was the carb float needle, allowing the engine to flood (I had also noticed some fuel on the floor of my trailer under the engine, but dismissed it). -Dana -- ________________________________ Message 4 _____________________________________ Time: 06:19:48 AM PST US From: "Jack B.

Hart FF004 Winchester, IN ???????????????????????? Do not archive. I checked out your spread sheet. And I extended your graph to include 100 mph. I did this by determining the hp difference in the previous two 5 mph jumps. There is an old statement that says,,, to double the speed requires 4 times the hp. Seems that your chart is very close to this statement. The one thing I had never done was check the mpg at different power settings. Thank you for your effort. Boyd Young ________________________________ Message 6 _____________________________________ Time: 07:48:20 AM PST US Subject: Kolb-List: Re: Hauck Ramblings On Kolb aircraft. From: "Thom Riddle" Nobody asked so if you are not interested in more detail about the data in my table, now is the time to move on to next post. However, I suspect one or two might be interested in the extra detail, so here it is. FYI regarding my spreadsheet table data. The TAS and Engine RPM were taken from actual testing, multiple times. The TAS being the average of GPS groundspeeds straight upwind and downwind. All of this was done at about 1,500' density altitude. The HP being developed(absorbed by the prop) and the fuel burn rate (GPH) was from the Prop Selector program assuming a fixed fuel consumption rate per horsepower hour, .42 lb/hp/hr quoted by Jabiru. As it turns out, the effective pitch of my prop 64x31 is closer to 39" according to the Prop Selector. The MPG was a simple division of MPH by GPH. If you look carefully at the data, you may notice a wrinkle in the MPG numbers between 65 mph and 75 mph, wherein the 70 mph airspeed yields a slightly better MPG than either side of this number. Either my numbers were off a bit during the testing or this happens to be the best speed for my Slinghsot that is a compromise between time-to-destination and fuel burn/mile. I suspect it is the later since these numbers are averages of multiple tests on different days. At higher density altitudes one can expect higher TAS for a given engine power output but it takes more throttle opening and higher RPM (fixed pitch prop) to get the same power output. I flew an hour plus taxi and warmup time this morning and climbed to 8,000' DA and measured a TAS of 84.5 mph at the same power setting as I see 80 mph at 1,500' DA. The rpm to achieve the same power at the higher DA I calculated to be about 2850 instead of 2712 at 1,500' DA. To maintain same power setting for a full hour, I did the climb at the same constant power setting gradually increasing rpm at a rate of about 25 rpm per 1,000' of increase in DA. After landing and refilling. I calculated my new fuel burn rate at this power setting to be about 3.5 gph. So, at altitude, I can expect about 24 mpg at about 84 mph. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 I am always doing that which I can not do, in order that I may learn how to do it. - Pablo Picasso Read this topic online here: http://forums.matronics.com/viewtopic.php?p=299727#299727 ________________________________ Message 7 _____________________________________ Time: 09:31:29 AM PST US Subject: Kolb-List: Re: Cuyuna engine failure From: "Mrikio" OK........ Think its solved To answer a previous post the cyl temps were 60-70 deg higher than normal,but not over the limit.I reduced throttle when I heard a power reduction and that dropped the temps more.I know from experience,when an engine stops,or wants to,full throttle will often kill it . A little power has helped me to find a better place to land 3 times so far. Fuel system checked out fine,from tank pickup to the carb. My system is probably the simplest out there..worked flawlessly on my phantom for 7yrs,200+hrs. A friend was helping me pull it down the other day,he said he checked the bottom of the bowl....I decided to check it again. Scraped the bottom of the cap that screws on the bottom of the bowl.....HHHUUMMM found a piece of dead grass 1/4" long and about .020 in diameter. It was curved on the inside edge of the cap,and the same color. I can see why it was missed,when it dislodged,I thought the cap was flaking aluminum. It was hidden VERY well,but this time I dried the bowl out. I suspect carb ice also,and now that I remember,I reduced the throttle as soon as there was a problem,then tried to advance it to see if it was just loaded up. Flew it again today(TUES) for 30 min....same normal temps.At cruise,CHTs were 260 .255 EGT was about 1200 or so. The fix?? the grass must have come up the vent tubes,so I will put a screen over them.(I fly out of grass,some of it gets a little high.) Also checked the torque on the cyl bolts...they are good. I thought John H would have a list of things for me to check,since he has a lot of time on them. Thanks to the list members who helped.....flying again,still working on the GENERAC conversion.... -------- Mark R Kolb Modified US Cuyuna UL2 60+hrs Kolb Twinstar,503,12hrs Phantom, Kaw 440 250hrs SE-5A UL 3 hrs Eipper Quick, Chrysler power Bee 8hrs PA28-140...350hrs Read this topic online here: http://forums.matronics.com/viewtopic.php?p=299742#299742 ________________________________ Message 8 _____________________________________ Time: 09:49:28 AM PST US From: Dana Hague Subject: RE: Kolb-List: Re: Hauck Ramblings On Kolb aircraft.

Actually, to double the speed (all other things being equal) it takes 8 times the power to double the speed. It's not quite equal, of course, and thus not quite 8X as at higher speeds the AOA and thus the induced drag will be less. -Dana -- Shaw's principle: Build a machine that a fool can use, and only a fool will want to use it. ________________________________ Message 9 _____________________________________ Time: 09:49:29 AM PST US From: frank goodnight Subject: Kolb-List: Summer flying Hi all, After a rather eventful and unsuccessful try at flying from Los Lunas , New Mexico to MV this year, I think it is about time for me to learn something about flying at high DA. So I rented a place at Mid Valley Airpark in Los Lunas where Mike and Jan Marker Live.

State the model of Kolb, engine, RPM, airspeed and any other notes you may feel are revelant. I guess John has gone first, so I will go second. MKIII, Yamaha Vector, 7000rpm, 70MPH. My engine does not have a published RPM so I cruise between 7000 and 7300RPM at 70mph to 75mph. If I fly faster than 75, my right door dimples in.

From: "Thom Riddle" Another variable, sometimes a pretty big one, is the accuracy of the airspeed indicator and location of pitot and static source. I don't know how many of the quoted numbers are TAS vs IAS. In most of the experimental airplanes I've owned, and even the SLSA I owned, the ASIs are notoriously inaccurate. That is why I take the little extra trouble to find the wind direction and makes runs directly upwind and then down wind to get the average GPS groundspeed, which is TAS. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 I am always doing that which I can not do, in order that I may learn how to do it. - Pablo Picasso Read this topic online here: http://forums.matronics.com/viewtopic.php?p=299772#299772 ________________________________ Message 21 ____________________________________ Time: 01:41:19 PM PST US From: "John Hauck" Subject: Re: Kolb-List: Re: Hauck Ramblings On Kolb aircraft. > I am not an expert at all here, but look at the profile of the engines you are comparing...sure looks like drag to me, all other factors being equal of course.

The performance of a Kolb is the direct result of how it is built, how tight the fabric is shrunk, and how well it is finished. These are just a few of the contributing factors. There are others. Fine tuning stuff means a lot. The prop is the only connection between the engine and the air. Fine tuning a prop is critical, all 3 blades the same pitch. Pitch it WOT, straight and level flight, so it will just barely bump the max continuous rpm red line. Works for my airplanes and my boats. In fact, that is where I got the technique from 26 years ago, from selecting boat props. Top speed of my US and FS were both 85 mph, 35 and 40 hp respectively, using the same Winter venturi type asi that requires no static source, the monster that screws up asi calibration. Let me go back to fabric a second. Kolb wing bottoms are flat when they are not flying. In the air they are concave, the amount dependent on how tight the fabric is. Most builders stop shrinking before the fabric starts pulling tubes. I shrink to 350F, bend tubes, and my fabric is tight as a snare drum. Same shrinking philosophy on all three my airplanes. All good performers. Could be I have flatter wing bottoms than most. Again, my airplanes, my thoughts. I'll put my mkIII up against anyone else's. I like competition. Always said my mkIII was pretty much an 85 mph airplane no matter what I did to it. No matter how much hp I put on it, it would still be an 85 mph airplane. I don't tune for economy. I tune for performance and reliability. Been able to back that up with actual successful flights over the years. john h mkIII ________________________________ Message 22 ____________________________________ Time: 01:47:46 PM PST US From: "Larry Cottrell" Subject: Re: Kolb-List: Re: Hauck Ramblings On Kolb aircraft.

Keep flexing muscles- isometrics, they used to call it. After my accident, 16 weeks later I just got up and walked. A little stiff and sore, but didn't need rehab because of all the cheating. The worst time was when I was in a cast and lost all the meat on one foot. Took quite a while to come back from that one. That, and the time they operated for carpal tunnel on both hands at once. Fun time in the bathroom with that one! You can still drive the Kolb with an elbow and your knees. Doug Bader showed how to do without both legs. do not archive Bill Sullivan ________________________________ Message 24 ____________________________________ Time: 02:43:36 PM PST US From: robert bean Subject: Re: Kolb-List: Re: Hauck Ramblings On Kolb aircraft.
