    --> Kitfox-List message posted by: Michael Laundy <mikelaundy@yahoo.co.uk> Yes I am using a portable radio. I tried linking to the antenna mounted on the aircraft and that line was dead. I tried using an extension lead with the antenna that fixes to the radio, and as soon as I moved the antenna 2 ft from the radio it started making a loud feedback sound (without transmitting). I plan to meet up with a buddy with a similar radio to do a comparison and try to find where the fault is. Mike kitfoxmike <kitfoxmike@yahoo.com> wrote: --> Kitfox-List message posted by: "kitfoxmike" Is that the portable radio? if so, what are you using for an entenna? If it's the portable radio I use the same one for a secondary, but I have yet to use it in the airplane, I have it set up to just use the units own entenna. If you are using an external entenna, you might have the entenna hooked up wrong. If your using the units entenna, you may need to hook up an external. -------- kitfoxmike kitfox4 1200 912ul speedster http://www.frappr.com/kitfoxmike Read this topic online here: http://forums.matronics.com/viewtopic.php?p=24144#24144 ---------------------------------

    --> Kitfox-List message posted by: HLJacoby1@aol.com Hi Michael, I too have an IC-A24 radio in my plane. I had the same problem and found it was the 12 Volt power adapter causing a low frequency "growl" when I transmitted. I pulled the power adapter, and the "growl" went away. I have not contacted Eastern Avionics about this problem yet. I have been running on the internal battery with no problems. I have a Rotax 582 in my KF-II, and I also have a significant amount of ignition noise on receive with the engine running. I am hoping a set of resistor plugs will ameliorate the problem. I am using an external antenna on the radio. Best of luck to you. Jake Jacoby Kitfox Model - II N7183H

    --> Kitfox-List message posted by: "kitfoxmike" <kitfoxmike@yahoo.com> I had a bunch of problems with my 912. If I had the strobes on and at an idle, my transmissions were bad. I also had problems with a noise in the headsets. I installed the recommended 24000mf capacitor into the system and it helped a little, then I went and put a ground buss on and put all grounds to this. That helped even more. Then I found my stereo was putting out noise and put a gound loop interface on the speaker outputs to the intercom and that took care of the rest. Now i can have everything on at idle and tower isn't complaining because they can't here me. -------- kitfoxmike kitfox4 1200 912ul speedster http://www.frappr.com/kitfoxmike Read this topic online here: http://forums.matronics.com/viewtopic.php?p=24351#24351

    Subject: Model II tail & 3 questions
    --> Kitfox-List message posted by: "Grant Bright" <gbright@bellsouth.net> Hello All, Been reading the list for a while now and really appreciate how great this Kitfox list is. The help and good nature of everyone is very enjoyable and informative. I've got the bug to get a Kitfox, but don't have the $$ to get a model IV with a 912. Am looking at a model II that has had a model III tail installed (several years back) to improve handling. 1) Is out of the ballpark (Braves fan) to even think about exchanging the wings and building series IV wings? 2) How many hours, with good care, can the 582 run? 3) Is pulling the head and de-carbonizing the pistons a regular event? Or is a motor that needs this running too rich/too much oil injected? Not sure if there are many Kitfoxes in the Atlanta area (?). If there are...we ought to have a fly in or a get together. Many thanks for all help.

    Subject: Re: Model II leading edge
    --> Kitfox-List message posted by: Jerry Liles <wliles@bayou.com> There were some who did use the leading edge cuff and claimed better performance. Perhaps they did get a bit better top speed, but maybe not. Personally I'm skeptical. The undercamber wing is designed for STOL performance, a broad leading edge allows for a bit higher angle of attack. If the leading edge cuff is installed as a droop type then it will accentuate the effects of the undercamber and it may improve STOL a bit, but maybe not. I think it adds weight and complexity to a design noted for light weight, simplicity, good STOL performance, and tremendous fun. It is an airplane designed to go out and "commit aviation" just for the heck of it. It is a pasture airplane, not a high speed go somewhere airplane unless you have lots of time and enjoy seeing the countryside from low and slow (which I highly recommend). Keep it simple, keep it light, and you'll keep it fun. Add all the bells and whistles and it'll be a Kitpig and it still won't be fast. Jerry Liles James C.

    Subject: Re: Model II tail & 3 questions
    --> Kitfox-List message posted by: Jerry Liles <wliles@bayou.com> Personally I don't see why you would want to go to all the trouble of changing wings. The Wilson undercamber airfoil works wonderfully for the Model II but it is possible to make a new set. The larger tailfeathers are good for better longitudinal stability . The 582 is recommended to be a 300hr TBO. Follow the maintenance schedule. There are those who run them a lot longer but the succesful ones fly frequently, don't abuse the engine and keep a close eye on performance. Perhaps Mr Robertson will chime in on maintenance. The Model II is a good, fun, low and slow, and cozy kind of airplane. If built lightweight the shortfield performance will astonish you but you will be very intimate with any passenger and you shouldn't be in a hurry to get anywhere Jerry Liles Grant Bright wrote: >--> Kitfox-List message posted by: "Grant Bright" <gbright@bellsouth.net> > >Hello All, > >Been reading the list for a while now and really appreciate >how great this Kitfox list is.

Hello Allan, sorry for the late answer, I was in Poland for business, and couldn't check my email before now. I am very pleased with my TruTrak Pictorial turn coordinator. It's the small one (2 1/4") as it is what fitted my panel. Like they say, the moving sky (vs. the moving plane in a traditional turn coordinator) is easier to interpret (in reality your plane is the instrument and doesn't move). I have tried it with a hood and it is very easy to keep the plane on a straight level as the instrument is very, very sensitive to roll. It has no moving part (solid state) and only a step motor that moves the background blue (sky) half circle. At US$ 445, it is worth it. Cheers, Michel

I have to agree with Jerry, Grant. I have a beautiful model 3 and I don't see why I should need anything else. Why would you want the model IV wings? To fly faster? But then you'll have to look at the angle of attack and thickness of the windshield. How about the flaperons? Do you intend to change them too? I think you should keep things as they are and spend time flying this fun plane, instead of building something new. I had a 582 engine on my Kitfox, until I changed it for a Jabiru last winter. The 582 (and Jabiru!) are great engines. The former requires probably more care, as Jerry says. I used to open the engine and de-carbonise every 50 hours. But I don't think it was really necessary. I sold the engine at 270 hours and it went in our club's Rans and flew another 200 hours, I think. The engine can run more than the 300 TBO but you should have someone who knows about the Rotax to have a look at it. If the engine has the old crankshaft (before 1993, I think) you may need to change it at 300 hours. Or, you can try to get hold an engine block from a new "blue top" 582, as I know of a friend who did it. As an extra measure of safety, I also purchased the Conrod Clearance measuring tool. A simple device that can measure the slack you have in your engine, crankshaft, conrod and piston. I used to measure it every 10 hours and plot the clearance. As long as it is constantly well under the tolerance, there is nothing that will happen dramatically to you engine so fast. Give it a good maintenance and you will love it. I am sure Bob Robertson, our Rotax specialist will confirm that. ... this being said, the Jabiru is a very good engine too! :-) Cheers, Michel

    From: "James C. Hartford" <jhartford@hartford-engineering.com>
    --> Kitfox-List message posted by: "James C. Hartford" <jhartford@hartford-engineering.com> Thanks for all of the input. My objective is a light plane with almost no bells and whistles. I am looking for good short field performance and do not much care about speed. If the original design worked well I plan to leave the leading edge on the rack and continue with the original Model II design.

    --> Kitfox-List message posted by: "Bradley M Webb" <bmwebb@cox.net> Absolutely awesome post! I'm still chuckling. Bradley -----Original Message----- From: owner-kitfox-list-server@matronics.com [mailto:owner-kitfox-list-server@matronics.com] On Behalf Of Jerry Liles Sent: Sunday, March 26, 2006 10:54 AM Subject: Re: FW: Kitfox-List: Model II leading edge --> Kitfox-List message posted by: Jerry Liles <wliles@bayou.com> There were some who did use the leading edge cuff and claimed better performance. Perhaps they did get a bit better top speed, but maybe not. Personally I'm skeptical. The undercamber wing is designed for STOL performance, a broad leading edge allows for a bit higher angle of attack. If the leading edge cuff is installed as a droop type then it will accentuate the effects of the undercamber and it may improve STOL a bit, but maybe not. I think it adds weight and complexity to a design noted for light weight, simplicity, good STOL performance, and tremendous fun. It is an airplane designed to go out and "commit aviation" just for the heck of it. It is a pasture airplane, not a high speed go somewhere airplane unless you have lots of time and enjoy seeing the countryside from low and slow (which I highly recommend). Keep it simple, keep it light, and you'll keep it fun. Add all the bells and whistles and it'll be a Kitpig and it still won't be fast. Jerry Liles James C.

The help and good nature of everyone is very enjoyable and informative. I've got the bug to get a Kitfox, but don't have the $$ to get a model IV with a 912. Am looking at a model II that has had a model III tail installed (several years back) to improve handling. 1) Is out of the ballpark (Braves fan) to even think about exchanging the wings and building series IV wings? 2) How many hours, with good care, can the 582 run? 3) Is pulling the head and de-carbonizing the pistons a regular event? Or is a motor that needs this running too rich/too much oil injected? Not sure if there are many Kitfoxes in the Atlanta area (?). If there are...we ought to have a fly in or a get together. Many thanks for all help.

I am not sure if > it is aircraft interference or a fault on the > radio. has anyone else had this problem? Hi ! Michael, I am a retired electronics tech but sometimes that still doesn't help. Anyway I have an Icom A20 mounted on my panel. It works fine now ! It is fed power from the plane and has an external antenna. It is connected through the intercomm. I bought the plane secondhand and it came with lot's of noise in the radio and intercomm. I made up a filter cicuit to feed the power to the radio and the intercomm. This solved all my problems. The circuit is very simple and anyone with very basic electronics skills could make it. If you would like the circuit contact me direct and I'll send it to you with a few comments. Now another instance we just sorted for a friend with a Rotax 277 in a 95-10 Ultralight. He uses a Delcom AIR960 handheld radio in the plane. He has a headset on it and that's it. With the engine stopped or at low RPM it was fine but by the time you got up to arond 5,000 RPM or more no one had a hope of deciphering his transmissions. He could recieve fine. We tried lot's of things with no luck. His radio was fine in my plane and my radio was fine in his. Just his radio in his plane and only on transmit at higher RPM was a problem. I have David Clark HD10-30 headsets and we tried one of mine in his plane with his radio and that cured the problem. Don't ask me why because I can't explain that but it did. Anyway in the end we just changed his microphone for a David Clark M-1 and it's fine. We tried many other headsets and none were any good. Some worse than others. As I say I can't explain this but I am passing it on in case it helps. Rex.

    --> Kitfox-List message posted by: "John Anderson" <janderson412@hotmail.com> Did another 3 circuits after changing the heater feed line to radiator return pipe and temp dropped approx 10deg. I also added another exit vent in the top cowl so this may have contributed also.Seem I might be heading in the right track. Just can't get over how nice the Kitfox flies too!! Taxiing out and the tower informed me that the grass was closed!!! So seal it was, planned to to leave it for a while until I was more at home but it tracked as straight as a die, very pleased indeed after all the discussion re toe in etc. John A.
