There should be a little for you to read right now(?), so I'm just sitting back and waiting for some response.. :) As you'll see the list is moved to another site, but still "maintained" by our friends over there.. ): Today, the Sun started the descend below the horizon up here, so from now we'll have "the theoretical night, well quite real too" in my place of the world.

Interesting point, Torgeir! I never thought of that but it makes sense and as an instinctive reaction, I've never changed speed or direction under a side-slip, feeling that the plane was not under those conditions "flying" but rather in a delicate manoeuvre that was not to be disturbed. BTW, I am back from a very pleasant European trip (in airliners, not Kitfox! :-) You guys managed to write 200 emails while I was away. Much to read! :-) Cheers, Michel

    Subject: Re: Elec trim indicator
    --> Kitfox-List message posted by: "John E. King " <kingjohn@erols.com> Torgeir & John Anderson Thanks for the pictures. I wish I would have seen them when I was building. I fixed my problem today by doing what Peter Graichen suggested. I went to the local Honda motorcycle shop and purchased 16 feet of Bowden type cable to replace the original Nylaflow nylon tubing provided by SkyStar. I kept the existing ribbon spring trim indicator. It works fine now and should last for the life of the airplane. To all those who are building Series 5 and 6 Kitfoxes I strongly recommend you do not use the trim system indicator tubing provided by SkyStar. Based on my experience and that of several others on the list, it is a weak point in the design and will fail after extended use. It is a big pain to replace after the fuselage is covered and painted. Further it will place excessive loads on the trim jack screw and its electrical motor as internal friction builds up in the Nylaflow tubing, especially where the tubing bends. Thanks to everyone who commented on this concern, for a while I though I was alone with this problem. BTW, Elbie of AOA fame, is looking into using the same type of tubing for this application that he employs in his AOA design. It is much lighter in weight and has very little friction. Looks like there are several good solutions out there. -- John King Warrenton, VA Torgeir Mortensen wrote: >--> Kitfox-List message posted by: Torgeir Mortensen <torgemor@online.no> > >Hi John, > > >This is just how the "good thing" should look alike, IMO. > >Simple, failsafe and reliable, what more can you ask for?? > >PS: Just added the direct link to your pictures here: > >http://www.sportflight.com/cgi-bin/uploader.pl?action=view&epoch=1069446885 > > >Torgeir. > > >John Anderson wrote: > > >>--> Kitfox-List message posted by: "John Anderson" <janderson412@hotmail.com> >> >>I've loaded a couple of shots of my trim indicator to SportFlight.com >>-j- >>Gaming galore at <a href="http://g.msn.com/8HMBENNZ/2731??PS=">XtraMSN Gaming! >> >> >>

Cheaper? I have an operating electronic trim position indicator system, in final debugging at present. It isn't cheap to design anything electronic, especially if adaptable for many aircraft. There isn't enough demand in the KitFox group to justify a system that just works on the KitFox. The investment is nearly equal to 50% of engine costs, and we are still debugging. BUT we will have an extremely light weight system adaptable to any aircraft that shows trim in 10% increments If anyone interested e-mail me at EMAproducts@aol.com will give information. Mention you are on the Kitfox list ~ We also have the tubing available John King mentioned in his note. I am waiting for the distributor to verify with the mfg. of the tubing the % of expansion and contraction with large temperature variations, I have asked them to check from a minimum of -20F to + 115F Will have info early next week hopefully.
