Has anyone else had this happen? Would appreciate opinions as to whether this calls into question the structural integrity of the entire wing strut.

With that thinking, it has no structural value at all. I think my only concern would be where else there might be rust.

Anybody that is wondering about trailering a kitfox, I do it every flight. I pay zero for hanger fees, and I can go out in the garage anytime and work on my plane. It takes me 4 minutes to get off the trailer and ready to fly. The kitfox is made to trailer,and I wonder why more people don't do it. If you have your own strip I understand. It is like having a boat, some people like it in the water getting full of scum, and others like it in the garage to keep it looking new.

That is great information. I certainly agree that where else may be rusted does indeed have me concerned. As much as I dread it I am planning on taking off the fiberglass fairings and having a look at the whole strut unless someone knows a way to check it without taking off the fairings. Please correct me if I am wrong, but I do not recall anyone have this kind of issue with the struts. Will keep all posted on what I find. I do not want to even think about a strut failure. Thank again Lowell.

Yes, it will leave small punch marks on good strong metal but if the material is corroded ...you will know. How hard you strike the punch is a judgement call...but don't be shy. There are ultrasonic methods of NDT also available to determine material thickness but it will cost $$. Here is a link to corrosion from FAA 43.13 1B, CHAPTER 6.

I have used heavy duty R/C servos with great success. So much so that I am incorporating built-in servos on my Model 5, I have attached a photo of the rudder servo installation.

Of course there is more tie downs and I don't transport the plane with any fuel in the wings.... Then there is the whole thing about launching and retrieving the trailer.

You should be able to get the struts xray'd for a 4 hour call out. UT may be a bit cheaper but I can see either one running you more than 2-300.. a heck of alot cheaper than folding a wing or taking the time to pull the fairings.. plus, you still wont know what the ID looks like unless you have some form of NDE done. Make sure you tell them it is experimental, and they dont have to be an FAA licensed station to perform the inspections. -------- Leonard Perry Soldotna AK Avid "C" / Mk IV 582 IVO IFA Full Lotus 1260 95% complete Read this topic online here: http://forums.matronics.com/viewtopic.php?p=143656#143656 ________________________________ Message 12 ____________________________________ Time: 08:53:28 PM PST US From: Guy Buchanan Subject: Re: Kitfox-List: Electronic Rudder Trim At 06:31 PM 11/3/2007, you wrote: >I have used heavy duty R/C servos with great success.

Things have been getting a little chatty lately so I'm offering these reminders: 1. Please address the "Way to go's" and "I agree's" and "That's way cool's" and like non-informational responses directly instead of to the Kitfox list. That way it keeps things friendly while keeping the list "technical". 2. We've got some new people who haven't picked up on the signature. Please put your full name, location, and aircraft type / status in the signature so we can think of you as a human being instead of a handle. (At some time or other I hope to meet each and every one of you.) 3. Be careful to change the subject line when you change the subject. It really helps the archives and those who follow on the forum. (They usually use threading.) 4. Finally, please check out Matt's contribution page, (http://www.matronics.com/contribution/) and make a handsome contribution. Or just make a small contribution. Think of it as part of your annual. Think of it as part of the kit price. Please think of it.

Variable potentiometers are used to input a signal to the microcontoller and the servos follow the potentiometer position.
