My typical cruise speed is 82-85 mph at about 2725-2750 rpm with CHTs running around 250F. The oil temperature at cruise is generally in the 200F-210F and the EGT is rich at around 1200F at low altitude and lower still at higher altitudes. During climb at Vy (60mph) and WOT the CHTs go to 300-320F or so at 3,000 RPM. They might go higher if I continued to climb at full throttle but my EGT gets over 1350 so I back off the throttle or put the nose down to correct that. Because of the rich cruise and lean WOT condition, I finally got around to ordering a richer main jet and leaner needle jet which should arrive this week. If they work as suggested, I should be able to continue WOT climb at Vy and see how high the CHTs go. Also hope for higher EGTs at cruise and consequent lower fuel consumption. I'd like to see your numbers too. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Truth is what stands the test of experience. - Albert Einstein Read this topic online here: http://forums.matronics.com/viewtopic.php?p=344942#344942 ________________________________ Message 2 _____________________________________ Time: 03:47:57 AM PST US Subject: Kolb-List: Re: N1014S MarkIII Xtra first flight - Frank D From: "Thom Riddle" Frank, The NORMAL Jabiru scoops do not go to the prop.

The short story is that I lo st power on climb out at about 300 ft. Had a hell of a cross wind that had me crabbed about 30 degrees already so I only had another 150 degrees of th e impossible turn left. I made the turn all right, but without time for a s ufficient flair and ripped the left main gear off. I don't know the extent of the damage yet, it could be an easy fix or the fuselage truss may be jun k. I hope I can salvage it, just have to wait and see. The good thing is I got away without a scratch, although I can feel a twinge in my right clavic le area. Probably just pulled a muscle. CRAP!

Some 2 place Kolbs have one stick, others have 2. It would seem that flying with the stick off center would be a bit challenging as the stick is not directly between the legs.

I talked to my neighbor who helped me retrieve my airplane yesterday afternoon. He recalls flipping all three switches on my overhead panel just before loading my airplane on the trailer to haul back to my yard, so apparently the boost pump was on after all. Conditions at the time were low temps (low 80's) and very high humidity following the passage of thunderstorms several hours before. I checked the engine for seizure last night and there is no sign. The engine starts and runs normally. The fuel lines are firm and I can't find anything that would have obstructed the flow of fuel to the engine so the only thing I can come up with is carb ice. I've had the symptoms before and once actually found frost on the outside of the carb bodies when I was fast enough getting out of the plane. I wish I'd had the foresight to have checked Sunday night, but I wasn't the best investigator right then. I guess I'll never know.

Hart" Subject: Re: Kolb-List: Re: 447 quit Ed, The most likely place for piston scuffing is the exhaust port side of the piston. You can view this area by removing the exhaust manifold and observing the piston as you rotate the propeller. Check with your engine mechanic to find out what he did to the engine. If he honed out the cylinders and/or replaced the piston rings, I would put it through the engine break-in cycle. If it gets through the this it is should be ready to go. If you don't want to do this or it doesn't make it through the break-in test, you have to pull the heads and the jugs to check for piston scuff. If there is scuffing, I would remove the aluminum from the cylinders with muratic acid. If the piston scuffing is light to medium, I would remove the rings and using a fine broad file, and smooth the peaks to the point where the piston will slide just nicely through the cylinder. You can get away with this because there is very little side load on the piston when it is under the greatest heat and pressure loads at the top of the cylinder. In fact these scuff marks will enhance increased lubrication in the scuffed areas. Before re-installing the rings, use a fine jeweler's file to remove any burr caused by a scuffing along the piston land slot corners. Remove only the burr and nothing from the land on which the rings rest. Install the piston ring and check that the ring is free to rotate as far as the pin will allow it, and that the ring will slide freely and completely into the slot. Reassemble the engine and put it through the break-in cycle, and go fly. Jack B. Hart FF004 Winchester, IN ........................................... Can you send some pictures when you get home?

Originally they all had just the one stick in the middle and it is not challenging at all. After a few flights, it seems like it is right where it needs to be, and the place between the legs is good for a radio and switch rack. And I don't have to try and get my leg over a stick. Apparently the dual stick is now common, if I remember right (always a problem) the Hauck guys came up with the dual arrangement, and I think it is possible to retrofit. John? Others? Verify? Or am I all wet? One thing I moved; the original throttle for the MKIII which was in the middle, replaced it with an add on quadrant on the left sidewall, which I like much better. Kolb details are easy to tinker with, if you want it different, change it. http://www.bcchapel.org/pages/0003/kolb.htm Richard Pike MKIII N420P (420ldPoops) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=344998#344998 ________________________________ Message 11 ____________________________________ Time: 12:30:08 PM PST US Subject: Kolb-List: Re: Bad day at Black Rock From: "Kirkds" I'll send pics and info when I get home.

I think he said he, his brother Jim, and maybe Dennis came up with the design. Folks: My only involvement in the first set of dual controls in a Kolb aircraft was coming up with the requirement and testing the finished product. Brother Jim Hauck designed and fabricated the dual controls for my MKIII in 1991. He built the jigs, offered them to Kolb Aircraft, but they were not interested in our dual controls. Some time later Kolb Aircraft came up with their own design of dual controls. Brother Jim gave his dual control jigs to The New Kolb Aircraft Company. All dual controls being produced by TNK and Kolb Aircraft are Jim Hauck dual controls. Our late friend, Seth Mathews of Tallahassee, Florida, gave us engineering expertise for the project, but the idea was mine, and the majority of the project was the result of Brother Jim's expertise. I fly my MKIII from the right seat, use the right stick between my legs and the normal Kolb throttle in the center bewteen the seats. I long ago removed the left stick to make it easier for passengers to board my MKIII. I like my arrangement better than the center stick and throttle, or flying left seat and moving the throttle to the left side. I have no problem adjusting to either configuration, and have been flying both systems for many years. My biggest problem is adjusting to operation of the flap with my right hand. I keep reaching for the handle with my left hand when I start flying from the left seat. john h mkIII Titus, Alabama ________________________________ Message 14 ____________________________________ Time: 01:28:55 PM PST US From: "Jack B.

Not as bad as I first thought. Not good, but better than I expected. For Newbie and other lurkers. I didn't take close ups of each weld cluster, but not a single one failed. Where ever there was a separation it was because the tube ripped, not the welding. I hit pretty hard but I walked away without even a bruise. The truss structure absorbed the hit and left me unscathed. I am glad I was flying from the right seat, though. I don't think one of the tinker toy aluminum tube and pop rivet aircraft could have protected me like this. If you're out there Homer, I owe you a very big thanks.

It goes without say that any landing that you walk away from is a good landing. Paralyzed for life would not be a good thing. The Bad day at black rock, I remember the movie. That old saying caught on sort of like "Murphy is alway looking over your shoulder". But thank goodness for a good outcome. You sort of answered my question about having the stick in the center. In a time of quick decision, the stick was right there and you did not have to compensate for it being off to the side. David d.

(newbie) I haven't found I have had to compensate for stick location in a Kolb, whether it be in the center or between my legs. No matter what the stick's location in a Kolb, it is always there because the pilot has to keep his hand on the stick almost all the time the Kolb is in the air. john h mkIII Titus, Alabama ________________________________ Message 19 ____________________________________ Time: 05:25:18 PM PST US Subject: Kolb-List: Re: A little better day at Black Rock From: "Richard Pike" SS568 wrote: > Greetings Rick, > > You sort of answered my question about having the stick in the center.

Some of us have a bunch of time flying these things, and if it was a problem, we would tell you, because we would have already taken steps to fix it, and what we fix, we talk about. That's what we do, that's what the Kolb list is all about. Search the archives and see if you can find anybody unhappy with the stick location for the reasons you envisage-I don't think you will.

Start at: http://jackbhart.com/firefly/firefly.html If you proceed by "NEXT" you will follow the chronological changes in the FireFly. It first flew on 9/9/1999. Otherwise you can use the "INDEX" to explore various topics. This was one of the first FireFlys (FF004) and so many little modifications have been made to tailor it to the way I want it to fly. The third engine is currently under test. I hope you enjoy it. Jack B.
