    Subject: A New Temperature Control System
    --> Kitfox-List message posted by: Guy Buchanan <bnn@nethere.com> Hi all! Given the problems of shock cooling and seizure described on the list for the 582, I thought that if I removed the existing thermostat, then cowled my radiator, then contrived some kind of system that opened the cowl flap based on the coolant temperature, I might eliminate the shock cooling problem. The water would always circulate throughout the system, and it would be maintained at the proper temperature by the automatic action of the cowl flap. Has anyone tried this system? Do you think it would work? Does anyone have a line on a thermostatically controlled actuator that could drive a cowl flap? Thanks, Guy Buchanan K-IV 1200 / 582 / 99% done, thanks to Bob Ducar.

How about this, Guy: Remove the thermostat, install a cockpit-activated butterfly valve, before your radiator. For safety, the valve should be spring loaded to keep it open if the control wire breaks. I am thinking of something similar for the oil cooler of my new Jabiru 2200. Cheers, Michel

I took one of my eye balls out and dropped it down into the tank. I found some loose poly where the machining was done. If I remember, there is a lip of some sort at the bottom to prevent an "absolute" low point. In other words, small debris can remain trapped during the sump check only to have it float around once motion starts. It's on my list to one day fabricate a new header with these ideas. Smaller area at the bottom with a defined low point. Extend the fuel lines to the bottom of the header through a large screen located above the low point capture area. Have the outlet above the screen. Design it so it can be taken apart during a condition and cleaned. Let me rephrase my original post, the header works but I think it could be much better. Just wild thinking, Don Smythe N-998DS Classic IV W/ 582

The first thing I was told to do when I purchased my plane was to drill a hole in the thermostat. I spoke with one of the Rotax gurus at LEAF and he recommended the same thing. For awhile Rotax was selling them with the hole, now I guess there isn't one? The whole idea of course was to circulate a bit of water at all times, with thermostat opened or closed. I drilled a1/8" hole on the very top in the kinda recessed area. It takes a good 10 minutes for operating temps to come up, summer in Wi. Don't know how winter will be. Sorry I can't comment about the results of this, but in theory, it sounds good.... Rody

I put 3 1/8" holes in mine and works good. I had to trim the Rotax gasket because was covering the holes. I think the holes also provide a path for air to escape?

Seems I read or heard somewhere that this is OK to do. When I first started operating, I had massive RFI interference in the radio. I had moved my ignition modules to the firewall and that seemed to have created an even worse RFI problem. I did every fix in the book and ended up with no noise. That included Resistive plugs and caps. I don't know which single fix I did (if any) made the biggest reduction in RFI. Don Smythe N-998DS Classic IV W/ 582

    Subject: Potential Fuel System Problems; was: Location of Fuel Filter...
    --> Kitfox-List message posted by: "Clifford Begnaud" <shoeless@barefootpilot.com> Here are a few things to consider about your Kitfox fuel system, especially if you have recently made the first flight or are about to do so! Be absolutely sure that the finger strainers are in place!! If not in place, a leaf or some other debris could easily block the 5/16" exit port causing fuel starvation. If no finger strainers are used AND you have the glass filters, they can be blocked even more easily than the exit port of the tanks! Many wing tanks have not had all of the fiberglass "Release Agent" completely removed. This release agent could then work it's way through your fuel system if finger strainers are not in place. Even if they are in place, some small pieces could still get by them. You can recognize the release agent easily as it looks like bits of clear silicon caulk. Removing the finger strainers at about 100 hours and cleaning the tanks is a good idea. Be certain that the fuel lines make an uninterrupted downhill run from the wing tanks to the header tank. NO rises allowed. The next potential problem is fiberglass. The tanks have baffles built into them with holes punched in the baffles to allow fuel through. The edges of the holes are NOT sealed. This leaves the raw fiberglass exposed to the fuel. You can get LOTS of fibers passing through your fuel system! The glass filters placed inline before the header tank will do a good job of capturing most of the fibers. These fibers are small and mostly transparent and you really CANNOT SEE THEM!! What you will notice with the glass filters is that they become slightly discolored by the fiberglass fibers. They can become covered enough to restrict fuel flow, so replace the filter element at the first sign of discoloration. In fact, in a new airplane, replace them every 25-50 hours for the first 250 hours; no kidding, the fiberglass can continue to be an issue for that long. In my opinion, this is probably the best reason for using the glass filters. If one of them get blocked by fiberglass, the other one will likely still allow some fuel flow. If you have no filters before the header tank, the fiberglass can make it's way through the header tank and block your final filter . Bad thing, very bad thing. On a new airplane, the glass filters give instant feedback to fuel condition and TANK condition. You can always remove them after a few hundred hours and after you feel comfortable that all the junk is out of your tanks. If you use the glass filters, you will need to be aware that the rubber o-rings could be a potential problem, particularly if you use auto fuel. In some parts of the country the additives in auto fuel do bad things to rubber. Keep spares in the plane & change the O-rings when you change the filters. As for having extra fittings and restrictions in the fuel system as Darrel mentioned, I generally agree. But I have found that the glass filters do not pose a noticeable restriction problem. You can, and should test this by checking gravity fed fuel flow at the carb(s). As for making a mess when changing filters, I placed fuel shutoff valves above the filters. This makes changing filters mess-free and gives you and easy way to drain a tank if needed. (not an unlikely event with a new plane) Once you feel comfortable that all the fiberglass and other junk has been washed out of your tanks, the valves and filters can be removed. One last thing. On our first kitfox we had no fuel pressure gauge and flew it that way for 1000 hours. Our new kitfox has one and it has signaled fuel restrictions problems twice now. You can bet that any plane I own from now on will have a fuel pressure gauge. It needs to be one sensitive enough to accurately read the low pressures of a gravity fed fuel system. Without the fuel pump running, readings will be from 1/3 to 1-1/4 psi depending upon sensor location and fuel level. In summary, I think the glass filters are a tool and can serve a useful purpose, especially for new planes. However, it is entirely possible that glass filters located prior to the header tanks may be subject to blockage from some type of fuel contamination that otherwise might be captured by the header tanks. I don't know what that contamination would be, it's up to you to weigh the possibilities. Cliff Erie, CO Kitfox 5, Lyc 0-235 PS. the info about the punched baffles was told to me by another kitfoxer. I have not opened up a tank to verify this. In any case, lots of fiberglass will be released by new tanks.

The holes in the baffles looked like they were punched out with a dull cookie cutter. Fragments hanging everywhere. I used a Dremel tool with round sanding drum to clean all the edges then carefully coated each edge with a thin application of gas proof epoxy resin. Even with all that and perfectly clean tanks, I still had to clean my filters every few hours during the first days. I got what looked like a clear slime for at least 3 tanks of fuel.

    --> Kitfox-List message posted by: "flier" <FLIER@sbcglobal.net> By the way, I have a friend (Tom Street for any who know him) that has the dual kill switches on his 912 Speedster. Couple of yrs ago, at a flyin, just standing around the plane talking and he pulled the prop over to move a blade outta the way. THE ENGINE FIRED. Thankfully he wasn't directly in the way and it shut down almost immediately. We never did figure out what happened. Checked all the grounds and everything was good.

    Subject: 912 bad ignition sw
    From: "Steve Magdic" <steve.magdic@1psg.com>
    --> Kitfox-List message posted by: "Steve Magdic" <steve.magdic@1psg.com> I beg to differ. I had a low battery situation which would barely turn the 912UL over. I flipped the mags to off and went to hand turn the prop to get the oil out of the crankcase and back into the reservoir hoping that would let the engine turn over easier. When I grabbed the prop and pulled it through it fired right up! One of the mag switches didn't stay down. Needless to say, I was VERY luck that day. I immediately ran around and hit the mags. No damage or injury... thank the Good Lord. It CAN be done. Steve M.

I did its imposable. Not to say that its a bad ignition sw is ok, its just a 912 will not produce spark until 1200 plus RPM. Paul

    --> Kitfox-List message posted by: Jerry Liles <wliles@bayou.com> Michael I think the tank would be stiffer because it would be thicker. Cured epoxy is a solid and rigid and thicker solids are stiffer or more rigid. Glass fibers only supply tensile strength and require a rigid matrix - epoxy or polyester - to hold a shape and provide rigidity.

    ters --> Kitfox-List message posted by: Jerry Liles <wliles@bayou.com> That's a good way to clean the filters. I completely drain the fuel system at each condition inspection (it helps to fly a bit before hand so the level is low). It makes it very easy to completely go over the fuel system and replace filters and any hoses required. If I need to clean the filters before that I use Lowell's method, however, I haven't needed to do that since the first 50 hours. The glass filters really do work well and it is nice to be able to see if they become contaminated but they do require maintenance.

    Filter... --> Kitfox-List message posted by: "Lowell Fitt" <lcfitt@inreach.com> Cliff, A couple of ideas. First, I agree wholeheartedly about the advisability of finger strainers. I have checked them at each annual for five years. I have found occasional debris on the strainers, but the most significant was a piece of rubber just the right size to block the line at the filter if it had been allowed to pass. I always run my fuel through a Mr. Filter when fueling at home. The rubber had to have come from an FBO somewhere when filling with 100LL. My presumption was that the FBO's system was serviced and when reassembling a piece of rubber was scraped from a hose by a fitting. That said, it is my belief that the tanks are built from a female mold and the mold release would be on the outside. This was discussed during a thread on Kreem and mold release was suggested as a possible contaminant reducing Kreem adhesion. The fiberglass fibers is definitely an issue. There was one long ago report of fuel starvation in flight and a forced landing. After a minute or two the engine ran fine again. What was found was that a mat of fine fiberglass particles had formed in the gascollator and when the engine was shut down the glass fiber mat settled to the bottom freeing up the screen for normal fuel flow. I have found that the rebuild kits for the Purolator filters - new element and "o-ring" - have a newly designed ring seal. It is no longer an o-ring but a square cross section with a cupped depression that fits the edge of the glass tube essentially centering it in the seal. My guess is that these are formulated for the newer formulations of auto fuel and since they are primarily directed at the auto market would be fine for auto fueled airplanes.

    Subject: Re: : REPLY: Wood Props/ Float Planes
    --> Kitfox-List message posted by: <av8rps@tznet.com> Robert: I had two different Avids of my own that I flew on floats, plus another that belonged to a friend (I test flew it and then flew the 40 hour test time off for him). None were amphibs, just straight floats. All used the Avid fibreglass float. I don't have a particular preference for a wood prop. I would think most any reputable brand would suffice. My first one was the Avid (a.k.a. Kitfox) prototype with a 43hp Cuyuna snowmobile engine (that particular airplane is shown in the info on the sportflight site). It used a 2 blade wood fixed pitch wooden prop made by Ted Hendrickson. I believe it is a 72" diameter, 36" pitch if I remember correctly. Btw - this was a great little two seat float plane. Flew countless numbers of passengers of all weights (it was Avid's first demo, so it gave lots of rides besides all I did later in it's life). Empty weight of that Avid on wheels was 364 pounds. It would climb about 1000 fpm solo on floats on a average summer day. My second Avid was an A-model that was powered by a 532 Rotax liquid, using a 71-37 Perry two blade fixed pitch wood prop. Absolutely an awesome performer. Weighs 396 pounds on wheels. Would consistently climb at 2500 fpm in the winter on wheel-skis, around 2200 in summer on wheels, and about 2000 on floats. For any of you that don't know him, John Knapp of North Carolina flies an airplane pretty much the same as this airplane, and he holds a world record for the shortest water takeoff. 2.7 seconds from idle to liftoff! (Really) It is so quick off the water that they've asked him to stop competing at the Greenville Maine seaplane fly in contest because if he shows up people wouldn't bother to enter the contest. He uses a set of Zenair (750?) floats that are extremely light (but underfloated). And he has tried every two stroke under the sun, but ultimately went back to the 532 Rotax. For overall hp, the early 532 develops the most hp per pound due to large ports (mine dyno'd with a stock muffler at 74 hp). He also has fun at Oshkosh every now and then by seeing how big of a person he can take up with him. I have seen him load a 280 pound guy in it, and still only need around 10 seconds to get off (incidentally, 10 seconds is good for a Supercub operated solo). The latest Avid I flew on floats was a 618 Rotax powered Mark IV. Had a Warp Drive 2 blade ground adjustable 70" prop. It weighed 625 pounds on wheels. It too was a nice two seat floatplane, but nowhere near the short takeoff capability of the earlier and lighter 532 powered aircraft. In fact, it performed on par with the 43 hp prototype on floats. On land, the lighter prototype was superior in STOL capabilities compared to the 618 Mark IV. The best climb in the Mark IV was around 1,000 fpm. However, the Mark IV flew 10 mph faster than the prototype, was more comfortable, had more range, could carry more, and offered space for baggage. The 532 powered airplane was slightly faster however. So, if you haven't already figured it out, seaplanes perform best if kept light. The floats are bad enough, but extra airframe weight will kill performance. It's all about power loading and wing loading numbers. You compare those numbers between all these models and you will find the 532 Avids will have the lowest combined numbers of the airplanes discussed (adding wing loading numbers and hp loading numbers together [based on empty weight only, no people, baggage, or fuel] the 43 hp Prototype is a 12, the 75 hp Mark IV is a 14, and the 74 hp 532 A-model is a 9. The lower the number, the better they will perform) I've learned a long time ago the secret to seaplane (or landplane) performance is not necessarily to add more power. It is the best combination of horsepower with the lightest overall weight. At least that's my take on it... Hopefully this info can help any of you considering the float option.

Figured the o-rings would be made for auto gas. They are just as you describe. Here's the link: http://www.jcwhitney.com/autoparts/ProductDisplay/s-10101/p-1675/c-10101 Note that this link has the filter assembly and filter replacement kits. The replacement kit has 3 filters and 6 O-rings. These units are on my plane now. No leaks yet after about 75 hours. Best Regards, Cliff

You're right, though, I'll need some way to force the door open if the control system fails. (Or make it single failure tolerant.) Guy Buchanan K-IV 1200 / 582 / 99% done, thanks to Bob Ducar.

I thought, for some reason, that cold seizure was one of the dreaded things living with a 582. Maybe it is not that big of a problem. Does anyone else think it's a problem worth addressing?

    Subject: RE: Cold Seizure
    --> Kitfox-List message posted by: "Gary Algate" <algate@attglobal.net> Although we hear about cold seizures in two stroke engines these are more related to snow machines than aviation use. Although the parameters for cold seizure exists in both applications most aviation users monitor egt's and coolant temps and therefore make sure they keep the temps in the green.(Below 1200 degF EGT and above 150deg for coolant The worst scenario for a cold seizure is a long descent in sub Zero temps as in an extended final and then a sudden application of throttle as in a missed approach and go-round. Basically the engine is cooled during the descent and coolant temps can drop below 140 deg and the cylinders contract around the piston. This is not a huge problem but when there is a sudden application of throttle the pistons heat up with the flash heat of combustion and start scraping the walls off the cylinder - sometimes you will get away with it, other times the pistons seize in the cylinders greatly reducing the noise output of the engine.... The best way to prevent this is by a) controlling the coolant temp by using adjustable rad cowls or masking off the radiator in winter months to ensure the temps are raised to normal operating levels b) control EGT's by monitoring and adjusting mixture and pitch accordingly c) Planning flightpath so long descents at low RPM are avoided This is another great feature of in-flight adjustable props as when I see my temps dropping I go to fine pitch and increase engine RPM to keep coolant temps in the green. When buying a 2 stoke engine it is a good idea to pop the carbs and look at the piston skirts to see if there is any sign of cold seizer (vertical grooves and scratches and bluing) Gary Algate Lite2/582

    Subject: Rotax two Stroke in-flight failure question.
    --> Kitfox-List message posted by: "Gary Algate" <algate@attglobal.net> I believe the aviation version of the 582 is a lot different from the 583. The 582 Blue head uses the 618 crank which is a lot more sturdy - also the aviation 582 is basically de-rated (especially with the Kitfox exhaust system) so you are not pushing the engine anywhere near its self destruct capacity. - Bob from light engines can shed light on these facts. You still can't beat a 2 stroke for HP to weight ratio and with aircrafts our weight a 582 produces a heck of a lot of performance. Like everything else aviation you have to mitigate the risks so you stay within the safety envelope and carry out maintenance and checks according to the equipment you are using. Based on this philosophy 2 strokers are as safe as you make them.

    Subject: Re: Model 5 Door latches
    --> Kitfox-List message posted by: John King <kingjohne@adelphia.net> JIm, My experience in the Series 6 door latch (same as the Series 5) is that the space between the the door latch and that of the bottom door frame is critical.. If too great, the door will sometime open unexpectedly on its own in turbulence or at the higher speeds. My pilot side door did that until I built up the striker plate a few thousands.. If you build it up too much the latch will not latch all the way on its own. I made a small hook to pull the door latch completely shut. and it works fine. I also noticed that the pilot side door has a tendency to pull open a little bit at the front edge in flight and I have to close it up by pushing on the rear of the door slightly. My guess is that it might be affected by prop wash. The left door does not do that.. It is my opinion that at least the pilot side door should have a door latch at the front, as well as at the bottom. -- John King Warrenton, VA Jim Corner wrote: >--> Kitfox-List message posted by: Jim Corner <jcorner@shaw.ca> > > >What is the experience with the door latches on the model 5. >Acceptable, or should I fabricate a dual latch system instead of the >supplied single latch at the bottom? > >Jim Corner > > >

    Subject: Rotax Thermostat
    --> Kitfox-List message posted by: Lmar <my93avid@yahoo.com> A few years ago someone suggested using a Bombardier "Evinrude/Johnson" thermostat part # 3853799. It is rated at 160F instead of out 130F. I have been using it in the winter only(changing to the Rotax in the spring). I have found that it keeps the temps at operating value more easily than the 130F one. With the 130F, as I powered back, it was almost like water temp came down in direct response with the throttle. With the hotter thermostat, I still cover the rad on cold days, but engine temp management is much easier. Larry --------------------------------- Express yourself with Y! Messenger! Free.

    --> Kitfox-List message posted by: Jerry Liles <wliles@bayou.com> Michael You are entirely correct about the utltimate strength of fiberglass being in the glass and about the desirability of just enough epoxy to support the glass. I also do not dispute your credentials as a designer, in fact I find them quite impressive, and I'm certainly not going to dispute Loyd's about strength and safety of vessels. My own boating is limited to pirogues and John boats on the Louisiana bayous and occassionally trolling for alligators (water skiing). My point was only that the tanks might be more rigiid, or less flexible, because there was a thicker layer of epoxy present I did not say the tanks would be stronger or even that the extra epoxy was desirable from a structural point. In fact since it is not supported by a web of glass fibers it is more likely to crack if too thick.

    Subject: Re: A New Temperature Control System
    --> Kitfox-List message posted by: Jerry Liles <wliles@bayou.com> Cold seizure of the 582 is more likely due to incomplete warm up of the engine before flight. On really cold days there is a risk of over cooling on prolonged descent at speed or, even, flying at low throttle settings. I make certain I have a good part of the radiator masked off on cold days for this reason. I also tend to descend at very slow speeds sort of hanging on the prop to keep the engine warm until I get low enough that I want a bit of extra speed for stall protection if the engine does quit. I keep thinking some kind of cockpit adjustable radiator louvers would be useful, like cowl flaps on air cooled engines.

Not to argue but, if you look inside the cowl with a magnifying glass you will see a small 4 sided square hole (the back side of the cloth that is not filled). That little 4 sided hole is multiplied by the thousands over the inside surface. If you fill up that one hole, you will strengthen the area around that one hole. Now, add that by thousands and it adds some strength. By design, it might not supposed to do it but, it does. It kind of only makes sense that it would add something.

    Subject: Re: Rotax two Stroke in-flight failu
    re question. --> Kitfox-List message posted by: "Bruce Harrington" <aerowood@mcsi.net> Hi Robert, #1. Yes. #2. No pictures. I riveted a piano hinge on the rear bottom of the radiator. Riveted a flap to the hinge (opened to about 75)(flap ends had 90 flanges for strength). Riveted a flange at the top center of the flap for attaching a control cable. Made a bracket to hold cable housing on the top of the radiator and riveted it there. Ran the cable to a home made bellcrank attached to the lower horizontal firewall plate (1:2 ratio to increase throw at flap). Ran a vernier control cable from the bellcrank up then back and thru the vertical firewall. Made a bracket to hold the control cable vernier end. Attached the bracket to the diagonal brace that goes from the front floorboards to the top of the front of the seat truss. This worked flawlessly for many hours of flying. Full open in summer, usually fully closed in winter. I also used the 160F OMC thermostat. Even then, coolant temps dropped to or below 140F on descents to land. I started with plastic wrapped around the radiator for winter flying, but had to have different lengths depending on the expected air temps. Flap cured this problem.

Not knowing for sure whether that applied to the 582's or not, I decided to perform the same fix. Get the modules off the engine. I also did some web searching on the subject and found an article stating, the 582 modules do not like heat and vibration. Getting them off the engine and onto the firewall fixed all the concerns. They work nice and are shockmounted. I came close to putting them on the backside of the firewall but running the wires was too much a hassle. Don Smythe N-998DS Classic IV W/ 582

I am not but I have worked with fiberglass on new work and on repairs. And if you don't mind, I would like to share my comments base purely on experience and not science I thought tensile strength was related to the stresses as if you were pulling the component apart. Like in stretching a rubber band or two Dutch men fighting over a penny and making copper wire. I don't think a fuel tank or cowling requires tensile strength built into it as an engineering factor. If any composite component, whether made from epoxy or polyester is cured through and you apply the correct resin (epoxy for epoxy and polyester for polyester) over the unsanded (You should sand with P60, P80 to P120 grit). Then you will have adhesion problems. It aint goin to stick, the more thickness you apply, the more it will fall off, through flexing or constant vibration. So I would not try to coat the inside of the fuel tank, 'cause I can't get in there to sand. As to the fabric lay-up, The fiberglass or carbon fiber, sheets (laminates) by the time you have finished should have enough resin to completely wet the woven material but not so much as to run off if the piece is vertical or "lake" puddle if the piece is horizontal. Any more resin than complete wetting is a waste (no added strength without the extra sheet of glass or carbon). If you inspect the cured article and close up you find minute square pocket holes. This tells you that the fabric lay-up was not wet enough. Is it a bad thing? not necessarily. As long as the first layer or two had sufficient wetting you should be OK. Unless this is a wing! The mistake has been made. Good fiberglass work should look pretty. The same as welding, welding should also look pleasing to the eye! Could you try to smooth things out and wet the system after full curing? Lets say that the pocket holes are 100% clean, no dust, no oils etc. You could get some adhesion but I would not trust it. As to wetting the glass or carbon fiber and getting better structural integrity = No. You may even try to laminate a new sheet of glass but that would be like using the original like a mold with very poor release qualities.
