    Rick- When my 5" wheel is installed, I had about 1/8" clearance, after grinding some off the lower strut flange, installing the pivot bolt from the bottom up, and grinding the bolt head into a round head screw with a slot. I wonder if mine is really old, and they used a 4" or 4 1/2" wheel originally. Bill

    This is not the Hexadyne P-60, but the Aero-twin. On paper, the P-60 looks good, but it is a radial mounted engine instead of bed mounted. The Aero-twin looks REALLY good, but that $10k price [w/ all the necessary goodies] for an un-tried engine [at least on a Kolb] is a bit much. If I's rich I'd get an HKS.

When the HKS came out, there was no good, reliable, light aircraft designed 2 cylinder engine available on the market, then trying something new made sense. Also the HKS design is very good for reliability and aircraft use, NOT so with the Aero Twin. Now, the HKS is available, proven reliable, and in use on many types of aircraft for the same price as the new engine... So why be the test case with an inferior engine, when the reliable, proven HKS is available at the same price ? If you took the time to look at the manufacturers website, there are plenty of pictures of the engine from many angles. Given what I see of the pictures, the design of the Aero Twin is inferior to the HKS, I would not want one, to many mistakes and compromises in their basic design to make it a good airplane motor.

The Oleniks are smart guys and do good work, so I'm sure they're going to come up with a reliable mount. The HKS looks like the best contender for that gap between the 503 and the 912 which is currently occupied by the 582 and some other 2-strokes. The clever thing they did with the HKS is made the operating RPM's and gearbox ratios very similar to the 582 and its gearboxes. So you're not in totally unknown territory when it comes to prop selection and operating rpm etc..... I still think it's a bit heavy for something like the FS II, though it does seem to work. It looks tailor-made for something like the Slingshot tho.... LS -------- LS FS II Read this topic online here: http://forums.matronics.com/viewtopic.php?p=163410#163410

Flying an underpowered plane and running the engine full out most of the time is definitely not as fun or rewarding, or as safe as flying a plane with a proper amount of power. Just because it you can do it does not mean you would want to. It all comes down to money, if you are able, get the 912-S, it is by far the best engine to put on a Kolb MK III. Work overtime, do whatever it takes to put the best engine you can afford on that plane, it will make the difference between having a plane that is fun and enjoyable to fly, and building a plane you never really like. If you cannot afford the 912-S, I would look for a used one. If not that, I would look at the VW Rick talks about, if not that, I would look at the 582. If you cant afford at least the 582, I would not build the MK III. If I was stuck with nothing but a 503, I would build a firestar-II which is smaller, lighter, and will give acceptable flight performance with a Rotax 503. -------- &quot;NO FEAR&quot; - If you have no fear you did not go as fast as you could have !!!

    Subject: Kolb Laser?
    Looking in some old Experimenter magazines a friend gave me, I see some pictures of "Homer Kolb and his latest design, the Laser", a nice looking low wing plane. I'd never heard of this aircraft before; whatever happened to it? 1990 was a very good year for Kolb, with an Ultrastar as the Grand Champion Light Plane, a Firestar as the Grand Champion Ultralight (!), and another Ultrastar (built by a guy I knew in college, small world!) as Reserve Grand Champion Ultralight. Interesting how many Firestars were passed off as "ultralight" back then... -Dana -- I only drink to make other people more interesting.

    Group, I am still plagued with too high of exhaust temps. I have tried different jet needles needle jets and main jets but there seems to always be a hot spot between 4000 and 5200 rpms. Question what is the minimum exhaust temp that is recommended for the Rotax 447 ? On climb out with the 170 main jet i am seeing 1000*. At other rpms, egts will get to 1150 or 1175. Will it hurt anything if I run it with the EGTS at 1000* I have it propped for 6250 static and the heads are at 350 *or so most of the time. This 447 is such a royal pain. I am thinking of getting one of those in flight adjustable carb mixture controls if I can. Ed Diebel FF # 62 **************Biggest Grammy Award surprises of all time on AOL Music.

    Thanks, I flew / fly freight out of Dallas and Houston so I know about the b'chin' heat and humidity. Got used to it but never did like taking a shower with a set of new cloths and 35 minutes later being ready for another shower and another set of new cloths. I think with the breezy Kolb it won't be as bad. But I deffer to others about that. :-) Still like it better out here than Arizona which among other things with the influx of Califruties is turning into Taxzona. Oh less I forget you ain't seen no winds till you been to Arizona.

    Subject: Re: 447 exhaust temperarures
    Ed, Do you have an adjustable pitch prop? Actually 1000* degrees F is OK - go to much above that and I would start getting concerned. High EGT's often indicate you might need to load the engine a little more by increasing your prop's pitch. We set our new 447's to 5900 static (tail tied down full throttle) and get about 6000-6100 RPM on full throttle on takeoff. A little more pitch isn't going to hurt anything. Try it and see what it does. What's the EGT numbers doing when you pull back power some such as on final. For some reason I noticed that FireFly's have a tenancy to peak EGT's when power is reduced some, not completely on final. It's been so long since I touched our old Kolb FireFly, I can't recall what jets and needles we ran in it - I know for sure we changed the original main jet. There was a post about a needle to use to reduce high mid-range EGT temp's on 02:03 PM 8/11/04 -0400, by: Gene Ledbetter. Might want to take a look at it. I got the needle but hadn't tried it. jerb At 10:16 PM 2/10/2008, you wrote: >Group, > > I am still plagued with too high of exhaust temps.
