    --> Kolb-List message posted by: "John Cooley" <johnc@datasync.com> Hi Thom, What John said and.....You sit way down in the MK II (the enclosed version) and the MK III has flaps where the MK II has full span ailerons. The MK III has more ribs and is beefier all around. I can't tell you about the flying differences as I have never flown a MK III. I have owned two MK II's and am building a MK IIIC currently. Compared to the FS II the MK II has a little better roll rate, I assume due to the full span ailerons and control design. Maybe Brother Pike can compare the roll rates of the Mk III versus the FS II and give an idea of how the three models compare. Also for you folks that have flown the MK III with a center stick versus the twin stick setup, is there any difference in force required to move the ailerons due to the slight rigging differences? John you have probably flown both set-ups, did you notice any difference? I know that the aileron control rods can be moved in at the torque rod connection to help with control forces and I plan on trying this when the time comes, (see Richard Pikes website) thanks Richard.

MKIII has 6" instead of 5". Fuselage is much better designed, wider and stronger. I don't know much about the MKII. Never had any dealings with it except what I read on this List. john h MKIII/912ULS Titus, Alabama --

    Subject: Mk 11 vs Mk 111
    --> Kolb-List message posted by: Richard Pike <richard@bcchapel.org> No experience with flying a MKII. Both our on-site Kolbs have VG's and modified aileron linkage, so comparing them with a stock a/c might be irrelevant, but IMO, there is not much difference in the roll rates in our two. Both respond very well, there is a perceived difference in that the MKIII has a lower and more reclined seating position, whereas the FSII has a taller, more upright position. So your sensory feedback is a bit different, our FSII "feels like" there is more of a pendulum effect, in reality, probably not. I doubt there is much difference in the roll rates. Both are very much three axis airplanes, coordinated stick and rudder are mandatory for brisk response. The FSII has notably more dihedral than stock, and will fly hands off. The MKIII has stock dihedral and will not.

    Subject: Kolb 1986 Twinstar w Rotax 503
    --> Kolb-List message posted by: David Nagy <dcnagy@gmail.com> In 1997 I bought a Kolb Twinstar that had a 1986 Rotax 503 SCSI with only 30 hours on the Hobbs. I went ahead and got it N numbered and flew for another 45 hours or so. In that time I had one engine outage which occurred when I throttled back to idle before landing. Problem traced to clogged idle jet. And a couple years ago I had a mishap and I'm only now getting the Twinstar back together and ready to fly. Question: Is the nearly 20 year old engine ,even though it has low time , too much of a risk. I know Rotax suggests new crank and bearings based on age not just running hours. I've decarboned the heads, the rings are free and the I can still see the cross hatching on the cylinder walls. But it's the possible corrosion of the crank needle bearings that concern me. And to put a little more urgency to the question Rotax is offering a $750 trade in of older engines on a new 503 til the end of this month. The new engine would be nice with dual ignition and oil injection but it will always be a 2 cycle.. Just to dream on a bit has anybody out there put a HKS 700 on a Kolb instead of a Rotax. It seems it would be a fairly close match on power and weight and of course be a 4 cycle but at double the price! Dave Nagy

    Subject: Re: Mk 11 vs Mk 111
    --> Kolb-List message posted by: FlyColt45@aol.com My 2 cents - If this is a buying decision? I've owned and flew both, (MKII & III). Beyond what has been mentioned about the obvious structural differences; both are fine airplanes. The MKII with a 503 is a very capable machine; as there are many are out there - flying safely. For me, it was finances & opportunity that allowed me to move on to the next Kolb iteration; and I was also pleased about the larger wing spars & boom tube. My MKII had a 582 & MKIII - a 912. In my case, those features alone made the 2 plane's handle differently, but the MKII was safe and pleasure to fly. I flat/out loved my MKIII! I've seen "chubby" pilots fly "chubby" passengers in a MKII/ 503 with no problems : ) {may not help you much, but it was nice to reflect on those 2 planes} Jim: PA/FL do not archive

    Subject: "Magic Bike" flies again!
    --> Kolb-List message posted by: Kirby Dennis Contr MDA/AL <Dennis.Kirby@kirtland.af.mil> Dear Kolb Friends - I am excited to share the news with all of you that my Mark-III is up and flying again. Last time I flew my plane was in February. As you might recall, I removed the Verner engine in March, and began the process of installing a 912UL, which I purchased used from Barnstormers. Well, I finally finished the installation, and flew my plane on Saturday. I'm happy to report that everything worked as it was supposed to, and my half-hour flight was uneventful. Besides the engine swap, I also did a few minor modifications based on ideas we've discussed on this List ... things that add to safety & reliability, namely: - Relocated my BRS to above the cabin (was previously located behind pax seat) - Added a gascolator to lowest point in the fuel system - Added fuel vents to my gas caps that vent to overboard My RPMs are a bit low for the 912 - I will need to remove some prop pitch (currently set at 12 degrees - will change to 11) to get those RPMs up to 5500 at full throttle. Otherwise, all systems are working fine. Time to knock out the remaining 15 hours left in my Phase-I flight testing! Glad to be flying again - Dennis Kirby N93DK, 912UL, Powerfin-70 in Cedar Crest, NM do not archive

    Subject: Re: Ultrastar
    --> Kolb-List message posted by: <undoctor@rcn.com> Hello, I have an Ultrastar I'm currently rebuilding. I had the nose raised like a Firestar a few years ago. I bought a house and have been up to my eyebrows with it until now, so the Ultrastar just sat in all that time. In the interim, the fellow where I had my plane died and I had to move it in parts from there to here and now that I'm putting it together, I've discovered I left a box of parts. Missing is all the engine mount hardware. Would you be kind enough to describe the parts and the sequence they are installec? I understand the mounts are Lord mounts, similar to the ones on the Firestar, but the Firestar engine is right-side-up and the Ultrastar engine, of course, hangs beneath the mounting tubing. Any info you could supply me with would be greatly appreciated. By the way, I'm living in Bethlehem, PA. What part of the world do you call home? Regards, Davd Kulp

    Subject: Bing Enrichment Piston
    --> Kolb-List message posted by: "Beauford" <beauford@tampabay.rr.com> Kolbers... After a couple of folks mentioned it offline, one thing I guess I should put out on the wire is additional evidence that the carb enrichment piston played a role in the carbon problem... I previously mentioned that the mechanics discovered the bottom insert (rubber) in the piston was pushed up and permanently deformed away from the valve seat. They speculated that this could have been leaking raw gas into the carb circuit. The enrichment piston was replaced. The one hour and six minutes I flew it yesterday consumed just slightly less than 2.5 gallons... and most of that was hard running, up around 5900 to 6000, with occasional 3 minute bursts at 6500 or 6600. Before, it would have easily used over 3 gallons for an hour of average cruising around... more like 3.3 to 3.4. That gas was going somewhere, and based on the reduced fuel burn rate yesterday, I strongly suspect it was passing through the defective seat in that piston and going directly into coke production. Henceforth, I plan to yank that little item out and have a look at it on an annual basis... Before, all I ever inspected was to make certain that I could feel the piston hit bottom when I closed it. Obviously, that was not adequate. Will attempt to fly it again this afternoon, weather permitting... will measure fuel burn again. It's great to feel the wind beneath my Kolb wings again, instead of just the wind beneath my britches while driving back and forth to Sebring.... Regards, Optimistic Beauford

Ralph Ralph is certainly correct on this point but there are some things the FAA folks (well, at least the ones I've run into) will look at and some they will ignore. I've been asked several times if those tanks were a total of ten gallons and indicated, yes, they were. Seems as long as I was the only one in the craft, everything else about 103 seemed to go by the boards as long as the craft looked like a UL. And the FAA folks told me as much. Obviously, others will have different experiences. Jim Baker 580.788.2779 '71 SV, 492TC Elmore City, OK

I assuming you mean the choke, right? Does your's have a primer and a choke system?? Just looking for problems on mine, you know - things are starting to wear.

    Subject: Two tanks
    --> Kolb-List message posted by: "Domenic Perez" <perezmdomenic@plateautel.net> Two tank Kolbers, If using two tanks whose floors are at different levels in level flight, and using the usual Mikuni pulse pump, here is the $64,000 question. If one tank runs dry and starts sucking air, are the pulse pumps powerful enough to still pull the fuel from the non-dry tank and keep the carb's bowls full? Or is some of the fuel unusable? I've never run my tanks that low, so I don't know from direct experience. Don't want to find out the hard way. My setup is a line coming out the top of each tank (drawing from the bottoms through check valves that give weight to the fuel lines so they stay down) and joining at a "T" and on to the carbs. I have a primer pump, but no primer bulb. I also have an "equalizer" line between the two tanks. Does this equalizer do any good? My two tanks are mounted on the boom tube behind the 2nd seat and seem pretty close to being equal height on the ground, but I just never thought much about the tail being high enough in flight to make a significant difference. Thinking about it now. M. Domenic Perez Vaughn, NM Firestar II, 503 DCDI

    Subject: Re: Bing Enrichment Piston
    --> Kolb-List message posted by: "Beauford" <beauford@tampabay.rr.com> Brother Possum... Yessir... Doan' got no CPS.... However, in the Lockwood book, they call it a "choke piston with gasket...." It is part number 963-740 out of a 36mm Bing Model 54... And you shall know it by its black rubber underside if you are feeling sufficiently kinky to look there when it somes in the mail. The goons at the castle call it an "enrichment piston," and you will have to forgive me... I picked it up...(sure sign of a weak, or failing, mind...). To me, being a fossil, a "choke" is a device that restricts airflow by imposing a butterfly plate or somesuch across the airflow in the venturi.... This thing "chokes" nothing, but merely dumps raw gas into the equation... same end result, I reckon. At their advice, I removed the primer from my engine...and concurrently reduced the idle RPM from 2450 hot, to 2150 hot.... thus making it easier to start. So far it is working.... third pull seems to be the ticket. Their advice also included down-jetting the idle circuit from a 45 to a 40, claiming that it would be a tad more smooth, and that a 2000 idle could thus be approached without chattering the B-box... I assume that guidance is applicable only in a hot climate, but did not specifically ask. You are certainly correct, Sir... Things are most assuredly beginning to wear... In the interests of common decency, I will not go there in this post... Good luck with the 503.... gotta be a better hand to hold than this 447.... The game continues.

    --> Kolb-List message posted by: Ron <CaptainRon1@cox.net> Tell you what, I got a good laugh out of your post. In fact I am still laughing. Just for your information MMO has been around since George Washington met Lord Cromwell, in fact rumor has it that it was the edge. In fact claims have been made that we won the cold war because of MMO. On a serious note it is a magical thing it will fix anything at all. :-) do not archive ======================== but I certainly wouldn`t buy a brand called Marvels Mystery Oil as a matter of principle.

You sir are a journalistic magician.....I certainly enjoyed that story...and in our office,( I had to show it around here) we are all extra sensitive (or jealous maybe) to the market dominating position Rotax has in the small aircraft engine biz...and particularly amazed at the tactics they use , and still maintain that position. In our industry, we would be smashed by our competitors, boycotted by the dealers and disdained by the customers in a moment if we operated the way they do.

But I'm glad you and some of the guys enjoyed it... It felt good venting to pound it out that night. Frustration. Like you, I have often wondered how in the world the Rotax empire does it... I guess it boils down to the obvious... no real competition feeding into a captive, niche market.... If they were competing against Briggs and Honda in the lawn mower market, they'd likely have been gone long ago... Thanks for the note...
