    This is taking a lot more time than I thought. You may remember that in January I posted emails that all three of my propeller blades departed my Kitfox IV Classic with a 912S while in flight. I needed to replace the propeller, the engine mount and do some repair to the cowling. I ordered an IVO prop and it came some time ago. John shipped the new engine mount last week and the repairs are done. What I don't have is the drive lugs needed to attach the propeller. These are the female threaded lugs that press into the flange on the drive shaft. Neither Kitfox Aircraft nor Lockwood have been able to get them from Rotax. I wonder if any of you have some you don't need and would sell them (six) to me. Let me know at barry@pgtc.com. Barry West

I always thought it was that the graphite scratched the oxide surface off of the aluminum and left a spot for corrosion. But why would that be worse than scratching the oxide off with a scotch brite pad? Cause water or salt can displace the graphite? I really don't know. Or is it just an old wives tale? Randy, It's not a wives tale. I was only an aero engineer at Kennedy Space Center, not a metallurgist, but I saw a mechanic draw a line with a pencil on a piece of aluminum used on the Saturn V. I brought this to his attention and he laughed and gave me a rough time since I was just out of school and the new kid on the block. Long story short, for a $5 bet, we put 2 identical pieces of aluminum in 2 pull testers. One was scribed with a pencil line the other wasn't. During the pull, the piece scribed with the pencil cracked right along the drawn line and the other piece did not break. Could it have been luck? I don't think so, I had performed that same test in college and it did the same thing more than once. The carbon in the lead or graphite sets up stress corrosion in the aluminum and when you place the part under stress it doesn't take long for the crack to occur. It will even follow gentle curves. The humidity in the air and especially in a salty environment like the beach will cause this corrosion to accelerate quickly. Just leave a piece of painted chrome molly steel outside for a day and see how quickly corrosion attacks it.

    I flew the Kitfox Saturday for 2.5 hours. The ASI read about 10% higher with the static port disconnected. It reads a little slow with the static port connected and way to high with it disconnected. With 20-140 "Knot" ASI with static port 5000 rpm = 80 knots indicated = 95 mph ground speed on average with GPS " 5500 rpm = 87 knots indicated = 106 mph " no static port 5000 rpm = 88 knots indicated = 95 mph " " 5500 rpm = 100 knots indicated = 106 mph " Changed to a 0-140 "MPH" ASI no static port 5000 rpm = 102 mph indicated = 96 mph ground speed on average with GPS " 5500 rpm = 112 mph indicated = 106 mph " with static port "lost data" will have to test again : ) Note: At idle my throttle is 3 inches out. (idles very smooth at 1500 rpm) At 5000 rpm it is 2 inches out At full throttle it is full in and on take off I can feel the horse power increase all the way until the stop. Again I think there is a lot of horsepower not being used in cruise with this prop. New IVO IFA has not yet arrived.

    I just bolted my IVO right to the flange, I did throw away the bolts they sent and got some better ones. I also put lock nuts on the back as well. If you do use theirs, be careful that you don't bottom out before the bolts touch the blades. I also found that my engine was running very rough and many things attributed to this, one- floats another - the calibration of the carbs. Now I can idle all the way down to 1450 which is spec for this engine. Sure helps when landing. I can pull the throttle and come in nice and slow, makes for a beautiful landing. -------- kitfoxmike model IV, 1200 speedster 912ul Do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=107330#107330

    Thanks guys and sorry for a bit late answer. No, my spinner is glassfiber so I don't have a problem with lead/graphite pencil on aluminium. Lynn, you have also a Jabiru and the same spinner as me. Putting it on a lathe? Could be an idea but my off-center motion is much greater than what I could get from the thickness of the glassfiber. Beside that ... a lather! Gosh, you must be a rich (and ingenious) man! I hardly have anything more than a Swiss knife to work on my plane. ... okay, I exaggerate a bit here but ... a lathe? And knowing how to use it? Listen, did you also invented the wheel, or what? ... just kidding! Sunny weather in Norway brings the silliness out of me! :-) Cheers, Michel do not archive

    The 912 UL will go way past redline now level flight without using anything near full throttle. I forgot what kind of speed it was showing before I backed off the throttle. It climbs out at 5400 rpm indicated and has a static limit of 5200 rpm so I did not want to change to pitch on the 68" GSC. I will test it again before installing the new IVO IFA prop.

    Mark, You gonna have a speedy Kitfox on your hands once you get your prop(s) tweaked. I think you might find with the patriot that it will seem to coursen as you gain forward momentum plus you will have the electric control as well. . I mentioned Paul's IV on Floats and I think he has the same prop but it is cut to 66 " and that might contribute to his fantastic speed of 118 mph wide open on floats. You on wheels might see 130s yet. Keep us informed.

    Interesting Mark, Sounds like the static port is the better bet for you. Too bad the higher speeds were not true. Still doing well though. Mine was within 2-3 knots of correct with the static port too. I think you will really like the adjustable IVO in comparison. You can use all the power in flight for climb and cruise.

    Graphite and aluminum in the presence of water form an electrolytic cell. The corrosion produced is the same type as is encountered with aluminum and iron, or iron and zinc, Galvanic with aluminum the looser. When the first carbon fiber bicycles became available the carbon tubes were frequently bonded in aluminum brackets where the tubes clustered at the bottom bracket, head set and rear wheel brackets.

    Subject: Recovering from lost propeller blades
    Barry, I recieved an email today that my order for several sets placed back in Sept 06 was now being shipped... Hope to see them by weeks end. John McBean Kitfox Aircraft -----Original Message----- From: owner-kitfox-list-server@matronics.com [mailto:owner-kitfox-list-server@matronics.com]On Behalf Of Barry West Sent: Monday, April 16, 2007 6:59 AM To: Kitfox List; Pulsar-Builders Subject: Kitfox-List: Recovering from lost propeller blades This is taking a lot more time than I thought. You may remember that in January I posted emails that all three of my propeller blades departed my Kitfox IV Classic with a 912S while in flight. I needed to replace the propeller, the engine mount and do some repair to the cowling. I ordered an IVO prop and it came some time ago. John shipped the new engine mount last week and the repairs are done. What I don't have is the drive lugs needed to attach the propeller. These are the female threaded lugs that press into the flange on the drive shaft. Neither Kitfox Aircraft nor Lockwood have been able to get them from Rotax. I wonder if any of you have some you don't need and would sell them (six) to me. Let me know at barry@pgtc.com. Barry West -- 4:22 PM

    Subject: Model 5 STC
    Guy, We do have a FAQ page on the web although we have not had a chance to get info up on the page... As for the design changes.. I'll contact you off list.. but for the record there is not an upgrade for the Model IV 1050 to increase to 1200.. with one exception and that was specifically for float operations and that change was not encouraged. -----Original Message----- From: owner-kitfox-list-server@matronics.com [mailto:owner-kitfox-list-server@matronics.com]On Behalf Of Guy Buchanan Sent: Saturday, April 14, 2007 11:33 PM To: kitfox-list@matronics.com Subject: Re: Kitfox-List: Model 5 STC At 11:04 AM 4/14/2007, you wrote: A question for you technical guys. Is there an STC that allows you to increase the gross weight on a model 5 from the early 1,400 pound gross to 1,550 which was in the later model? The other posters are right. STC's only apply to certified aircraft. You can, as the builder, specify any gross weight you want. Now as to the structural mods required to go from Skystar's 1400 pound gross to 1550 pound gross you're asking a questing hashed out several times this year with, as I recall, no definitive answer. I certainly wish someone could find definitive design information for these aircraft. It would be a shame if it all just disappeared. John, did you get Skystar's and Denney's design information when you purchased the assets? Is such information available? Can we put together definitive information regarding the design changes to go from 1050 to 1200 for the IV, and from 1400 to 1550 for the V? Guy Buchanan San Diego, CA K-IV 1200 / 582-C / Warp / 100% done, thanks mostly to Bob Ducar. -- 4:22 PM
