    Subject: Re: needles for 447
    From: "Thom Riddle" <riddletr@gmail.com>
    Thanks for the needle solutions for your cases. Following is what I did yesterday. I re-pitched the prop again, this time such that I am getting 6450 rpm at full throttle level flight.... just right. I then flew for 2.3 hours with two stops en-route. The EGTs were running around 1100 +/- 25 during 5500-5800 rpm cruise with no problems in that range. BUT the needle clip is in the #4 (richest) position. Below 5500 rpm the engine is still unstable with RPM varying all over the place. After the flight I checked the plugs and they are about right. I removed the carb and took it apart. All the jets and the jet needle are per Rotax spec and in good condition with less than 70 hours on engine. The float levels are perfect too. Today I plan to order a slightly richer needle jet (2.72 vs current 2.70) and one each of the two jet needles that you guys stated solved your problems. With three new pieces the combinations of possible parts is quite large. I'll test them each one at a time and then in various combinations, if needed. In each case I'll put the clip back in the #2 position to begin with. I'll let you know what finally works for me (I hope). -------- Thom in Buffalo N197BG FS1/447 -------------------- &quot;Blind respect for authority is the greatest enemy of truth.&quot; Albert Einstein Read this topic online here: http://forums.matronics.com/viewtopic.php?p=125308#125308

    All, yesterday was a fine fine day in western NY. Thom Riddle flew over in his newly acquired FS and joined up with me and my ladyfriend for a 15 minute trip to a great fly in breakfast. Very well attended. Of interest was a huge biplane with a 330hp chev v8 and outboard motor redrive. We left before I got to hear it run. Our Kolbs drew a lot of curiosity seekers. My passenger weighs somewhere near 120 lbs which brought us to about 915 gross. It flew well but until some horsepower-tweaking mods take place to the little suzuki , no heavier passengers will climb aboard. first pic is Thom landing at my strip using the tassel guidance system. http://picasaweb.google.com/blitzsplyk/NewAlbum72307900AM? authkey=k4sMXZWAPJw

    At your altitude, you will want the 912 or 912s with a 72 inch dia prop. The HKS is not near enough engine for a MK-3 at high altitude and the Jab is limited to a 64 inch diameter prop, that is not as efficient as the bigger slower turning 912 prop. Mk-3, Mk-3 extra or Kolbra are your best bets. Sit in all of them and you will know what you want. Denny Rowe, MK-3

    Subject: Ultrastar Home at last
    From: "jb92563" <jb92563@yahoo.com>
    Hi Guys, I finally got my Ultrastar home....now Im Kolbing too! It needs a bit of work to get it flight ready. I has more hanger rash than I thought.....I will need to do a bunch of Polyfiber repairs to patch the 5 little(~1") tears hear and there. I also have one big tear about 6". I have been reading about the process to make the repairs and it seems simple enough, so I'll need to get one of those Polyfiber repair/practice kits. Anyone know of the best place to get one. Was the US covered with the Light or Medium Polyfiber fabric? The plane came with 2 Cuyuna 430's or UL11-02, not sure which they are yet, that have not run in about 5 years. Seems like I might have one of each since one has a single module with 2 spark wires and the other has 2 modules with 1 spark wire each. The ignition kill switch is disconnected from the engine and I read that using the wrong switch can destroy the CDI module, anyone know what I need so I don't fry the thing? I'll take some pics of the CDI modules/wires and post tommorow in case anyone can identify the correct wires. -------- Ray Do Not Archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=125347#125347

I'd say just go right to the 912s, the power reduction over sea level is substantial, at 6000' you'll be only around 70 to 75% throttle when wide open depending on the density altitude....

    Very true. I got fed up with oversize images & set up my email client to reject anything over 500K. This solves the problem of locking up my phone line, but I don't get to see a lot of stuff I'd like to see. What seems to be lost on people like Mike is that it's pointless to send images bigger than around 100K for viewing on a typical computer screen. The monitor just doesn't have the resolution to show that much detail. It also seems to be lost on him that methods of reading email, like choice of airplane, is personal preference. I find web based email clients and forum based lists extremely clunky & slow, even when viewed on a broadband connection. It's a real shame he takes that attitude, especially when the Matronics list manager has provided him the tools to upload even his huge images if he desires, without penalizing the rest of us.

    Mike, Cool Pict ! :-) Your 15.27 mpg works out to a fuel burn of - 4.25 gal. per hr. @ 65 mph 3.9 gal. per hr. @ 60 mph 3.6 gal. per hr. @ 55 mph Does this sound about right with your experience? I'm interested in finding out what others are experiencing in fuel efficiency.

Did the fan lock, or belt break? Hi Chuck, It would appear that the fan belt either broke or was slipping (check the fan holding nut to see if it is tight) for the fan not to turn with the crankshaft. That would result in getting the high CHT, as no cooling air would be coming across the heads.

    Subject: Re: needles for 447
    Thom, You say the engine only has 70 hours on it, but you don't give its actual age. Is it a new engine run at the national average 30 to 50 hours a year or an older engine that spent some time as a hangar ornament? Is the 70 hours since factory new or since rebuild? The reason I ask is this, the symptoms you describe are a mixture going leaner at higher engine vacuum. The further you get from WOT the worse the problem becomes. It' s beginning to sound like an air leak somewhere in the intake system. How is the idle range set? Is the idle air adjustment near the factory setting (.5 turns out for 447, 1 turn out for 447DC? The idle mixture circuit bleeds into the lower midrange. If you richen up the idle, do you see any changes in the middle and high midrange cruise where the anomalous leaning begins. Have you inspected and greased all the rubber fittings to make sure there are no cracks or delaminations. How is the condition of the crank seals? That's just some of the things I can think of off the top of my head. Something just does not add up for a 70 hour engine to require radical jetting changes.
