I find it extremely difficult to break the bead with any tire I have ever put on these 8" original Kitfox rims. I damaged the hub once trying to break the bead using a tire demounting device. For breaking the bead, I was advised to place the wheel and tire on the ground in front of my car tire and then drive over the kitfox tire. I hope this makes sense. It will break the bead without involving the rim in any mechanical device. Past experience suggests to me that tire slippage would be quite unlikely. However, I have heard of it happening to others.

Would only apply to a tubless tire though. You definately want to press on the tire only and not damage the rim. It doesnt take much to damage alum rims. If you drive over the tire, put some cardboard or carpet under it to save the rim from scrubbing on the concrete. Another try might be a LARGE C clamp placed right at the bead. I know of others who have their tires slip too. All I know were due to underinflation. Just some ideas. Of course you could try a tire place or 2 and see if their machine would fit?

On grass it takes a bit to move. If I use my normal takeoff power, I probably use 500 feet or 8 seconds to lift off of grass. (Timed from movie camera footage of my takeoffs from the cockpit.) If I use full power, which I can get with the cockpit adjustable prop, that last 300 RPM really peaks the turbo and you can feel the change. About equal to going from 2 people to solo. It is on the top end of speed where I seem to run out with this prop. More HP isnt going to more speed. On landing I am still trying to find a reliable way to set pitch for less float and yet have go-around power available. I can either float, or make a bunch of noise as I land when I wanted to go. So far, I try to set 2000 rpm at closed throttle and accept that, but I do float. Slips are very useful. Kurt S. --- John Anderson wrote: Yes, that makes good sense to me Kurt..well explained. I do find that it takes quite a punch of power to get the wheels rolling to taxi and on t/o the acceleration is gentle for a start but really begins to bite once she's up and away so that ties in. I'll take more notice tomorrow when I fly again. Took my boy yest (test engineer), first passenger and sure made a differance. John Forgot to mention the deacceleration, very little when you close the throttle thus requiring a bit of f/ward planning on approach and boy do I hate it when the tower askes for a tight approach. I've had to resort to side slipping a couple of times, seems to work ok? Any comments on this? __________________________________________________ ________________________________ Message 17 ____________________________________ Time: 10:27:08 AM PST US From: kurt schrader Subject: RE: Kitfox-List: Warp drive hub.Very Strange --> Kitfox-List message posted by: kurt schrader Well, first keep the fun part going John! To start with, I built in a fairing to the bottom of the verticle stab so that the fabric does not make that hard break to the horizontal stab enclosure. I also added foam into the gap between the inner ribs of the horizontal stab and the enclosure sheet metal so that the gap was zero with full nose up trim and less a gap for the rest of the travel. Those were the only drag reductions I built in. Cant tell you if they helped much or not, since I have no comparison. Filling the Horizontal inner gap should have helped with elevator effectiveness too, but I don't know for sure. I added a scoop to the radiator and gained about 9 mph. Less in hot temps with the exhaust door open. Took it off and added wing strut fairings and gained an average 10.5 mph. They do not add up to 20 total, but maybe a 16 mph gain together. I can't remember my top level speed right now, but it was nice to see. Still some to go. Michel and a French friend of his did extensive work on the wing strut fairing design and it payed off. Dont let Michel get away with playing dumb. ;-) Wheel fairings, wing strut end fairings, top and bottom, gas cap fairings, H. tail strut fairings, jury strut fairings, other things to go. I'll try to measure any improvements, if I can, for each. That makes twice that I had to learn, then relearn not to float. Releasing that drag made a very noticable change in the pattern requirements. And if you want to float lazily along at 65 knots or 75 mph, my Fox is now a very quiet and fuel efficient plane. But more to go. It is still working too hard past 85 knots (100 mph) for me. Kurt S.

This is why I don't want to do it myself, Lowell. I take the wheels to the workshop that does it professionally. They use a machine that turns around the tyre making a "poof!" sound. Cool stuff! Gary, the King Fox tyres are very good looking but, because of my wheel penetration skis, I can't use them without major modifications to the skis. Hence my choice for some slightly smaller tyres.

Pull a plug, insert the comp tester, crank the engine a turn or 2 with mags off, read the gauge, repeat on other cyl..

On t/o with the prop setting I have now, the diff between 4300 and 4700 is like day and night but as you say, it's the turbo boost at the latter setting that make the diff. I still need to coursen up a bit as full noise is still over 5000. If only I could get time to play...John --> Kitfox-List message posted by: kurt schrader Somewhat the same with me John. On grass it takes a bit to move. If I use my normal takeoff power, I probably use 500 feet or 8 seconds to lift off of grass. (Timed from movie camera footage of my takeoffs from the cockpit.) If I use full power, which I can get with the cockpit adjustable prop, that last 300 RPM really peaks the turbo and you can feel the change. About equal to going from 2 people to solo. It is on the top end of speed where I seem to run out with this prop. More HP isnt going to more speed. On landing I am still trying to find a reliable way to set pitch for less float and yet have go-around power available. I can either float, or make a bunch of noise as I land when I wanted to go. So far, I try to set 2000 rpm at closed throttle and accept that, but I do float. Slips are very useful. Kurt S. --- John Anderson wrote: Yes, that makes good sense to me Kurt..well explained. I do find that it takes quite a punch of power to get the wheels rolling to taxi and on t/o the acceleration is gentle for a start but really begins to bite once she's up and away so that ties in. I'll take more notice tomorrow when I fly again. Took my boy yest (test engineer), first passenger and sure made a differance. John Forgot to mention the deacceleration, very little when you close the throttle thus requiring a bit of f/ward planning on approach and boy do I hate it when the tower askes for a tight approach. I've had to resort to side slipping a couple of times, seems to work ok? Any comments on this? __________________________________________________ _________________________________________________________________ Discover fun and games at @ http://xtramsn.co.nz/kids ________________________________ Message 24 ____________________________________ Time: 02:00:12 PM PST US From: "John Anderson" Subject: RE: Kitfox-List: Warp drive hub.Very Strange --> Kitfox-List message posted by: "John Anderson" Yep, I did this too, added a profiled leading edge to start of the vert stab to split the flow. Guess it all helps for as I've said, up to 100kts is relatively easy. Hopefully after increasing the prop pitch and get the boost up a bit at lower RPM I might get a wee bit more..John --> Kitfox-List message posted by: kurt schrader Well, first keep the fun part going John! To start with, I built in a fairing to the bottom of the verticle stab so that the fabric does not make that hard break to the horizontal stab enclosure. I also added foam into the gap between the inner ribs of the horizontal stab and the enclosure sheet metal so that the gap was zero with full nose up trim and less a gap for the rest of the travel. Those were the only drag reductions I built in. Cant tell you if they helped much or not, since I have no comparison. Filling the Horizontal inner gap should have helped with elevator effectiveness too, but I don't know for sure. I added a scoop to the radiator and gained about 9 mph. Less in hot temps with the exhaust door open. Took it off and added wing strut fairings and gained an average 10.5 mph. They do not add up to 20 total, but maybe a 16 mph gain together. I can't remember my top level speed right now, but it was nice to see. Still some to go. Michel and a French friend of his did extensive work on the wing strut fairing design and it payed off. Dont let Michel get away with playing dumb. ;-) Wheel fairings, wing strut end fairings, top and bottom, gas cap fairings, H. tail strut fairings, jury strut fairings, other things to go. I'll try to measure any improvements, if I can, for each. That makes twice that I had to learn, then relearn not to float. Releasing that drag made a very noticable change in the pattern requirements. And if you want to float lazily along at 65 knots or 75 mph, my Fox is now a very quiet and fuel efficient plane. But more to go. It is still working too hard past 85 knots (100 mph) for me. Kurt S. S-5/NSI turbo --- John Anderson wrote: --------------------------------- --> Kitfox-List message posted by: "John Anderson" Lot of drag in these wee aeroplanes eh. I notice at cruise, drop the nose and it'll go easily to 110kts but big struggle to get it to VNE..What streamlining enhancements do you have Kurt? I'm still very much in the learning (FUN) area. __________________________________________________ _________________________________________________________________ ________________________________ Message 25 ____________________________________ Time: 05:37:56 PM PST US From: "wingsdown" Subject: RE: Kitfox-List: Trim servo If its the same as they use on the 5 I have one for sale.

If you don't have that spark gap when you create a spark you get a very high voltage build up and the solid state components in the modules might well fail. Then again they may not but it's certainly not a good idea to temp fate. When an ignition module fires it builds up voltage until it is high enough to jump the plug gap and then the energy is dissipated. With no plug gap to jump the voltage keeps building to a very high figure. Shorting the plug lead to ground [ the cylinder head or whatever ] will also stop the build up but may overload the module. The right idea is to have the plug lead connected to the plug and the body of the plug grounded. A plug usually fires around 25,000 volts but if the lead is left floating in mid air the voltage may well go to 100,000 with CDI.
