    this ? In General it is not the bolt that prevent the flange, prop or hub extension to move relative to each other it is the friction between them from the squeezing effect of the bolts, if the torque of the bolts is not enough the bolts will be sheered off in a short time. The small diameter of the hub extension is a different issue, it have to be analyzed and tested on each engine that take it. it is a big different from a 912 and 912 -S the torque of engine isn't the big thing here but torsion vibrations, and the -S is reported to be hard in this respect, there is additional items to add to the gearbox, making it a little better, but it is an option.

Here are some pictures of the prop spacer that goes from my Rotax 912-S to the Kiev Hot Prop. It is made out of aluminum and the shaft is tapered to only two inches at its narrow point.

All the spacers I have ever seen have the prop bolts go all the way through from the prop hub to the steel engine output flange.

After reading stories of high streingth bolts breaking on occasion, I am wonding how just 2 inches of aluminum could be safe to transmit 100 HP to the prop. Has anyone ever seen a prop adapter / spacer like this ? Is this very likely to fail and let the entire prop fly into the back of my Kolb ? Would you guys trust this ?

    this ? All other considerations aside, I think one important consideration would be if it is cast aluminum or cut from a solid billet. It it's cast, I wouldn't trust it for a minute.

Would you guys trust this ? Any thought you may have would be >appreciated. It looks nicely made, with adequate radii. Certainly the engine-side flange looks big enough! I would guess it's turned from billet but Clem's right, the material is important. Jan's right too, that the static thrust and torque loads are generally insignificant in the design of drive components. Much more important are the loads resulting from harmonic amplification of the engine's natural torque pulses. Given the right combination of engine / spacer / prop it is possible to generate enough resonance to be a problem. In the certificated world there are some engine / prop combinations which are forbidden for just this reason. Others have cautionary operating regions where resonances occur that are harmful, but not catastrophically so. The answer to your question is that the spacer can only be considered "safe" if your exact engine / spacer / prop combination has been tested, either on the bench, or in flight, for a given number of hours. (The airframe might also contribute to the response, but these engines are typically so softly mounted that you might be able to discount the airframe. Certainly any test will want to use a similar mounting system so the engine vibrates similarly to your aircraft.) The spacer could then be considered "safe" up to, and only up to, some fraction of that number of hours. If you can find no such testing then, guess what, YOU'RE THE TEST PILOT! Neat, huh? Looking at your spacer, and based on my experience in the world of recreational engineering, (that's engineering FOR the recreational industry, not engineering AS recreation,) a really good designer would start with the 912 output shaft dimensions. If they were really, really good they might do some hardness testing of that shaft to estimate its hardness. They then could design an aluminum "shaft" by similarity to give equivalent fatigue life. Unfortunately this design would completely ignore any system resonance modification induced by the spacer. And more unfortunately, the aluminum spacer will act as a relatively low frequency spring with negligible damping, capable of dramatically increasing the system resonance. I suppose a really, really, really good engineer would mount the stock engine / prop combo and run it festooned with accelerometers in an attempt to determine the system harmonics. They could then install the spacer and confirm the system response was NO WORSE across the entire operating range of the engine. You could then feel confident the spacer had not decreased the reliability of the system FOR THAT ENGINE / SPACER / PROP COMBINATION. You would, of course, have to run this test for every engine / prop combo. Finally note that I have quite obviously neglected the increase bending loads in the 912 output shaft caused by the increased prop offset. This works to reduce the fatigue life of the output shaft and bearings, particularly if the prop is not perfectly balanced. You would definitely want to make sure your system was dynamically balanced fairly often to mitigate this detriment. I've given you all this information mostly because I like to hear myself talk, ;-) but also to give you some questions to ask the spacer's designer. It's even odds you're operating as a test pilot. What do you do then? First you get parachutes for you and your passengers. (A BRS obviously counts.) Then you always fly high enough to use them. (You'll be at risk during take-off and landing.) Then you decide how long you want to do the test. To do that you note that you're going to replace a big chunk of the Rotax output system plus the spacer at some hours interval. (Let's say the output shaft, bearings, and spacer.) The cost of that replacement will help you determine how many hours you want to run between replacements. (Note that you don't get to fly up to the number of hours you tested, but only to a fraction of those hours to account for variations in fatigue life. What's the fraction? I don't know off the top of my head, but we could probably come up with a conservative value with some investigation.) Now I'd really better shut-up. Good luck!

    Subject: Kitfox to look at
    All, I have a person interested in my Fox. He is 6'3" @240#. He is located in Orem Utah (about 30 miles south of Salt Lake City) and has never really seen a kitfox. He is willing to travel up to 150 miles to look/sit/possibly fly in a Kitfox. Is there anyone in that area that could give the guy a look and at least let him sit in one. Quite frankly, I told him not to even consider purchasing a Kitfox or anything else until he could at least see one. He's operating on the Kitfox reputation only. Thanks, Don Smythe

    From: "akflyer" <akflyer_2000@yahoo.com>
    yikes... Years ago I grabbed the 152 from the local club to go spot carribou. After 3 hrs I had to swing into Port Alsworth as nature was screaming in my ear to "pull over". There was 4-6" of fresh fluffy snow on the runway, but I figured what the heck.. its 3000' long so it would not be a problem.. Landing was VERY short, and takeoff was aborted twice before I finally got that pig into the air... I had many soft field takeoffs in the plane before but never in snow....I would never have thought in a million years that only that little amount of snow would have that much drag. Now I dont set one down unless I am on big tundra tires (31") or skis / full lotus floats. -------- Leni Avid C W/582 1260 full lotus .......DO NOT ARCHIVE.....

    this ? Hi Team . I hope you all have very Happy Christmas.. Re the Prop spacer (if it's cast)...............It depends on several factors, what type of Al. is it made from, under what conditions was it cast, what was the casting medium,(die or sand, low presure or high) heat treated or not. To make the statment that one would "not trust it for a moment" is to not know the facts. Casting are used in every aircraft that ever left the ground, the wing pivot on F111 is one of the largest. Not one WW2 aircraft was built without castings, especially engine parts, as with everything, if it's properly engineered, and not done "on the cheap" it will be "fit for use" . I think the main problem with this spacer, could be one of balance, thus putting stress on the engine/gearbox bearings, how often is the full 100hp used or should be used??? Just my 2cents!!!!
