    Jim, The tire rating of 730 pounds is per tire your load would be distributed evenly over 2 tires. If enough force were to be placed on one tire greater than 730 pounds I would tend to believe you would end up with much greater problems.

    Hey Dave, Are you setting for 6800 wide open straight and level ? and what are you getting static? I set mine with a combination of RPM , EGTS with needle adjustment as necessary. Fuel flow increases with Needle clip change.

I was asking because I was at 6,200 and was happy. They said I was giving up a lot of HP at 6,200. Took a bit of pitch out of my IVO and it went to 6,400 to 6,450. It was a big improvement. I havent changed it since. I might take some more pitch out someday... These 2 strokes are a bit peaky and like to rev. Easier on engine but this topic has been there before...:-) Personally, I think 6,400 to 6,800 is ideal. Dave

    Malcolm, a large part of the wandering trim and rpm is that the model II being so light and with a low torque motor results in low overall inertia. Very small air currents and bumps will affect it. Heavier airplanes with higher torque engines are much less prone to this. It's normal.

    Hi Jim, I think they are a little light weight for us -5 and up drivers. I know I don-t always land squarely on both tires and at 1 G, so I think they are a risk for us blowing a tire and doing more damage. Probably no problem for the 1200 and under guys though.

    I Michel, You need to remember that the ski is flying in the air and not on it like on the snow. With the curve up, it acts like the top of a wing upside down and lifts down in front. Once it goes down a little, it will pull down hard because the axis is near the middle and not forward of the center of pressure, which is around 25% of the length.

Dave Well A GPS is a must for accurate #s Personally, my plugs would never see more than 50 hours, typically I change them around 30. They are cheap and I notice a small improvement in idle whenever I plug new ones in. I suggest following the Rotax manual. VNE is 100 I fly in East Central Illinois. About 100 Miles S of Chicago. We see a WIDE range of temp and Humidity. When flying cross country I fly at 5,000 ft or so. Local around 3,000. In cold weather, 30F to 0 F, obviously the EGT climb and in hot they drop. They highest I have seen is 1,350 at cruise. Raised the needle one notch and it dropped 50F. Personally I dont want to see over 1,300 ever. 1,200 to 1,250 is comfortable to me. I just took my engine to "theultralightplace.com" in Kankakee for its 300 hour medical. Doc Jim Leon said whatever your doing keep on doing it. He specializes in 582 and really knows these engines. So, for me, this combo seems to work well. Best Dave

    For those of you YouTube watchers here is an amazing video of a guy who straps a wing on his back with several rocket engines bolted to it, and then zooms around the (Swiss?) countryside. Just amazing. Oh and it is on topic because the launch plane looks kind of like a Kitfox. http://www.youtube.com/watch?v=dST-a5IU_h4 Don Pearsall

    Hi Folks, I'm going to be delayed a bit more in putting the fabric on our KF IV, as I have just been told I'm going to the US for a quick trip in late January. I have to attend a meeting or two in Rhode Island (not sure of the city/town just yet)for a few days, plus visit a couple of sites in New York city and Washington DC, and possibly a couple of other locations on the east coast. I may have a day or so free at either end of the business bits, so if any of you live within/near Rhode Island, or a modest distance from Washington (say an hour's drive), I'd love to meet you and have a look at your plane. >From the posts I've read before, a few of you seem to live in the North West corner (Oregon and Washington State), and I may (emphasise may) be able to divert through there on the way back. If you are open to a visit from a fellow Kitfoxer from "the other side" (of the planet) let me know. When I'm sure of the exact dates and routes, I'll see what can be done to drop in briefly. Regards Colin Durey Sydney - Australia 0418-677073

    Subject: Over-torqued GSC Prop
    I just ordered new blades from GSC as I've had my prop now for 10 years. The first question they asked when I inquired about the prop was whether there was a gap in between the hub halves. If there's not a gap, there's no question that the blades should be replaced. IMHO, don't screw around trying to shim. If the hub isn't holding the blades, replace the blades. Slinging a blade could end up killing you when the engine comes off. A set of 3 new blades is $450. Very cheap insurance.

I would like to add, indicated temp is like airspeed. The final word is the plugs. My Indicated Temps may or may not be accurate. I started off a bit cool (rich)... at 1150 F at cruise and the plugs showed cool... then went to factory settings and been there mostly since. Remember there are big differences from WOT and cruise temps as much as 200F cooler at WOT and this is on purpose... :-) Ho ho ho Dave

    Subject: Over-torqued GSC Prop-- Take out of service immediatly
    Dwayne, Call Rick Peters the owner if GSC at (250) 549-3772 or email him at info@ultralightprops.com I was just talking to Rick yesterday and I think he is shut down till Jan 3, but call or email to confirm. I would highly recommend that you take your prop out of service immediately. If you lose a blade you will destroy your engine mount and you could lose your engine and ....well you don't want that to happen. I have on mine a safety cable attached to engine and ties to fuselage under the dash. If that engine breaks free all that will be holding it on is the heater hose and fuel lines. Carbs will fly off. I have first hand experience in Prop departures in aircraft myself and have worked on others this year that have had the same. If the GSC alum hub halve blocks are touching that means that the root ends of the blades have been crushed. If crushed they will not only NOT hold the pitch in the hub but the grains of the hardwood have most likely have been compromised and you could be looking at failure at ANY time.

    If the aluminum clam shells are touching then that means that the wooden blades have been crushed at their roots...very bad! Sanding, milling, shimming, or filing the aluminum will only make the prop more dangerous! Do not try to jerry-rig a fix. Remove it, send it to GSC, and have them evaluate it. Throwing a prop and crashing because you did your own make-shift maintenance is not only bad for your health and insurance premiums, but it is another argument people can make against experimental aircraft. -------- Dave Speedster 912 UL Read this topic online here: http://forums.matronics.com/viewtopic.php?p=83130#83130

    Subject: Re: Ski installation
    Hi Lynn, Well, you should ask someone with more ski experience than me. I can only address the aero theory here to say what "should" happen. In theory, there is no difference between theory and reality. In reality, there is often a big difference. Remember, a theory is just an opinion by someone who thinks they are important. You get that in schools. Experience rules. You get that in life. In neither case do I claim to be important, just still trying to do my best to help. In theory, I expect that the bungy would pull up to the relaxed position unless unbalanced ski weight or aerodymanic force pulls it into tension. If it is aerodynamically pulled tense, then some force with resulting drag is being applied. If I am right, the force on the bungy is a vector equal to the lift and drag applied. Threated just like a wind vector, the aft part of the bungy pull is = to drag. The verticle part is = to lift (down) which the wing must overcome. At landing speed and angle of attack you still have some lift and drag on the ski. What do you ski flyers actually see happen? Kurt S.

    Don, Check the following link to see if any of these bottles look like yours. I'm away from my plane for a couple of weeks or I'd measure mine to correlate. http://www.usplastic.com/catalog/product.asp?catalog%5Fname=USPlastic&category%5Fname=15034&product%5Fid=14979 Let me know if this looks like yours. First, though, ask John if he's stocking any replacements at Kitfox. If not I'll talk you through how I did my bottle.
