I installed a low hour used one about 7 hours ago but it shows signs of heat damage already. I have a new set of bushings for the mount but don't want to put them on till I can figure out why the starboard one is getting cooked. The only theory I can come up with is that the air in the starboard side of the cowl is not getting refreshed, due to the fact that the exhaust on the cowl is on the port side. The mount castle nut is about a 1/4" above the muffler on both sides but the port side shows no sign of damage. If anyone else has had this problem or knows a solution please let me know.

Looking for trainer. Hi Guys, I signed up here quite a while ago, but never posted. I have been looking for a plane for about a year now, and had 2 partners bail out on me. So I am looking for something inexpensive for myself, to use as a trainer. I missed out on a deal yesterday on Ebay. I tired to use Esnipe to put in my bid at the last second, and it failed completely. Had I bid manually I would have won. It was a Kitfox 1 with 2 wings, and went for $7900. So that is what I am looking for, a Kitfox 2 or a 1 with 2 wings, I would like the 950 gross if possible. Does anyone know of one in decent shape, Rotax motor OK as long as it is low to mid time, under $9K, and within 500 miles of Elmira, NY? There is a nice Kitfox 1 on Barnstomers for $10K with trailer, which would be great, except it is 2600 miles away in Oregon. Someone must have one between here and there. :) Thanks, Andrew ________________________________ Message 16 ____________________________________ Time: 10:42:40 AM PST US From: "Bob Brennan" Subject: Kitfox-List: New member with UK-built Model II I would like to introduce myself to this group, I have been monitoring it for several days and am impressed with the wealth of knowledge and helpful Kitfox owners out there. First a tiny bit about me - I got my PPL in the US many years ago, training on a Tomahawk and doing business flying in Cherokees mostly. I moved to the UK for a while and recently got the urge to fly again - bought my Kitfox and trained for a full NPPL (EU equivalent of a PPL) to rebuilt my skills and make the full transition to the Kitfox. My model 2 was built in the UK in 1991 and was in good shape when I bought it, with about 800 hours on the airframe and less than 100 hours since a rebuild on the 582. I moved back to the US a while ago and brought my Kitfox over in a 20ft container. I haven't flown it here yet and have several questions that will hopefully put it back into top shape first. Most important question - the inboard leading edge of the flaperon has a steel rod that appears to have been held in with some putty, no doubt a bad repair. The problem is that the rod is the length of the flaperon, it is loose and slides easily, and the putty must have loosened sometime during taking the wings off and putting them back on. After a run-up &taxi and a post-flight inspection I discovered the putty had fallen out and the rod was extended into the flaperon linkage potentially locking the controls. Thank goodness it was only a run-up! My question(s) - is this a known problem? How should the end of the flaperon be sealed - it appears the port one has bent-over metal possibly epoxied in place? Should that steel rod be loose, and if not how should it be secured? What's the proper repair given that the end of the flaperon is now open? Thanks in advance, Bob ________________________________ Message 17 ____________________________________ Time: 10:50:19 AM PST US From: Lynn Matteson Subject: Re: Kitfox-List: Flutter of flaperons I don't think you answered someone's question about balance weights....do you even HAVE balance weights on the flaperons?

The plane had low times and was finished back 1996 so it sat more than flew. I decided to replace the fuel lines firewall forward new carb boots. I replaced the gsc with a warp drive. A friend of mine who owns a model IV flew the five hours off on the new prop as I don't have my license yet. Yesterday was my 1st flight it and seems that the rudder is really stiff at cruising speed. The rudder and stabilizer is not the airfoil style and is not gap sealed. My friend who's plane has the speedster tail said his rudder is alot easier than mine.

You might look for stiff bearings at the rudder hinge, or misaligned rudder bearings...if the rudder bearings don't all line up with each other, that condition will require high input force. Also, make sure that the rudder pedal bushings are free...you can lube them up nicely when you have them out for installation of the gussets. You ARE going to gusset them, aren't you?

I have taken and attached 2 pix for you, being new to the list I hope it works. The steel rod (PIC1) is about 3/8" solid steel and is 1/2 the length of the flaperon, In the picture I laid it on top for you to see. PIC2 shows it protruding from the leading edge where it should be inside and secured. The flaperons do not have the counter-weights to stop vibration as I have seen on other older models, however part of the UK annual airworthiness test requires the airplane to be flown at Vne (100mph for my model 2) and there was no hint of vibration or anything other than perfect operation of the flaperons.

Nick, another point to check is the tail wheel linkage attach holes of the rudder horn. It seems I can remember some people modified the rudder horn looking for better control while taxiing. Some drilled tail wheel spring attach holes inboard of the originals on the rudder horn, I think. The original tail wheel spring attach holes on the rudder horn are six inches center to center. Anything less will increase amount of pedal pressure required. -------- Tom Jones Classic IV 503 Rotax, 72 inch Two blade Warp Ellensburg, WA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=189148#189148 ________________________________ Message 36 ____________________________________ Time: 03:36:19 PM PST US Subject: Re: Kitfox-List: C Box and IVO props, now warp prop.

It should be. If not, find out why. 3. Are the rudder tillers too long? Do you have too much rudder throw? +/-30 degrees should be enough. 4. If you gap seal the rudder, you'll get a lot more effect around zero, a lot more "sensitivity". 5. Stupid question time. Are you pushing on both pedals when you use rudder? (Don't laugh, I've caught myself doing this innumerable times. Why? I don't know. Maybe I'm trying to be precise.)

I think I found the source of the story on the IVO web site. It's a service bulletin and has very little to do with 3:1 gearboxes, although they are mentioned. I think it's been heavily expanded upon by people repeating the story. The short story is that one series of IVO has a service bulletin when used on 3:1 box, or direct drive, or three cylinder engines. ----- Original Message ----- From: gary.algate@sandvik.com To: kitfox-list@matronics.com Sent: Sunday, June 22, 2008 7:32 PM Subject: Re: Kitfox-List: C Box and IVO props, now warp prop.

Gary & the others following this thread, or just lurking---- Somewhere I got the idea that the C and E box units, by having the stronger gear sets were supposed to help take care of the Harmonic/ vibration problems with the gears . When I decided to go with an Ivo- I called and told them that I had a C box currently with a gsc and-- the new power would be ( a blue head with an a 3.47 box E box,) Ivo did not recommend the ultralight 3 blade when I called, but did recommend the medium .. They sent a 3 blade medium ground adjustable, as I indicated that I wanted maximum STOL performance and did not care about top speed. Since then I became aware of the Service bulletin #17 and according to it, I can't use anything other than a 3-1 ratio with the side rail engine mount. SO I assume, they had never heard about the bulletin and probably would have told me to get a different set of gears --i.e. 3-1 ratio for the E box. I haven't called Ivo back yet , but from the gist of all the emails, it is looking more and more like I should mount the old 3-1 C box on the new engine and convert the prop to a 2 blade with Ivo's different spacers. Does this sound like a good idea to you ? Any of you folks out there with any bits of knowledge you have on this subject feel free to chime in, as I am really starting to get just a little confused :>) I really just want to install the E box with 3.47-1 and the 3 blade medium prop as it should give me terrific "bite" for take off performance !!!! But if it is going to tear the engine loose from the motor mounts or induce gear damage, then I will stick with what the Rotax engineers recommend.

In other words, it's a circle of belting material that has velcro attached such that it becomes a straight section in the middle with a loop on each end. The straight section is formed when the ends of the belt are wrapped around the harness and pressed together. I'm not explaining it very well..too late in the day...but the result is the shoulder straps are held together on your shoulders, yet the thing can be removed very easily if needed. I put mine behind the down tubes. Lynn Matteson Kitfox IV Speedster Jabiru 2200 Status: flying w/530 hrs On Jun 22, 2008, at 4:59 PM, Lowell Fitt wrote: > > > Thanks to all for the welcome.

Model 2 From: "Jeffrey Dill" <1dillfamily@comcast.net> I was sick for about six months, but got my medical back and am back to learning about this model 2 I rebuilt. I had a great day on Saturday. Flew some formation against a Thorpe Scooter, whose owner was delighted to be the faster of the two airplanes. With about 20 hours in the airplane, I have gotten so that I never touch the flap handle. What is it there for? To be able to fly slower without stalling? I guess I can go back and check how much difference that makes, but I fly final at least at 55 regardless, which is plenty above stall speed with any flap setting. You guys tell me that the flap handle is there to trim the airplane, but something about that doesn't square well. The faster you go, the more the nose wants to rotate up; that is basic longitudinal stability. To trim nose down, you must shift the center of lift backwards by putting flaps down further. Flaps are drag, right? Now, let me see if I have this straight. When I get to going fast, I either hold the stick pressure, or I add drag. Putting flaps down is going to fix the problem one way or the other because it is going to kill all the speed!Corollary question:What flap setting gives the best speed What are the three bolt holes at the leading edge of my horizontal stab? Am I free to experiment with using any of the three? Since my stab struts do not have turnbuckles, I would be warping the leading edge by choosing a higher angle of incidence. Any problem with that? One more thing regarding my 582. I have the carbs adjusted exactly even with each other with open throttle, I can't get them any closer. I am seeing some difference in EGT between cylinders at high power. Should I open up the cooler one a few turns? Wa-Hoo!, I am loving it. -------- Jeff Dill Model 2, 767JD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=189219#189219 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kitfox-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kitfox-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kitfox-list Browse Digests http://www.matronics.com/digest/kitfox-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
