I would to give two comments: 1- If someone is rerouting aileron cables around the landing gear mount, You might consider what I did which seems to work and is simple. Mount a pulley to the rear of the main spar just inside the fuselage skin and a second pulley on the fwd side of the rear spar so that the cable go thru the spar where it normally does. This arrangement give a solid mounting point for each pulley. 2- I can't really tell for sure but I think the control stick that you are using is copied from the plans. If so, when the control stick moves fore and aft, the aileron cables will be stretched each time causing a lot of unneeded pressure on the whole aileron cable system. What is best is a control stick in which each axis movement(one direction) caused no movement in the other axis(the other direction). Just food for thought.

In my opinion, a low time pilot..like myself, should not fly a KR with no experience in type or a comparable plane. Part of the problem with homebuilts is that people build and do not maintain flying proficiency. My first time in a KR (Troy's) was probably typical....up and down chasing the stick. After Troy showed me how to steady my hand on my leg...I was fine. Now imagine flying it for the first time with no experience in type. Sure you may survive but why take the chance. There are enough KRs flying with people willing to take you for a ride NOT to get time in one before you test fly one.

Absolutely correct, even for a high time professional test pilot. Also, if you are not current AND competent in type/similar type, you shouldn't be flying the test flights, anyway. But as far as a low time pilot flying a proven KR after an appropriate amount of dual, I don't think there is a problem. Keep in mind, however, that what is appropriate for one pilot may not be nearly enough time for another pilot. Use your best judgement, your life depends on it.

When I first installed the aileron cables, I saw the problem you describe. I attributed it to the arc described by the aileron cable as the stick was moved fore and aft. I replaced a fairlead mounted in the fuselage with a guide pully mounted to the mains bracket. This lengthened the radius of the arc and seemed to have solved the problem. I just completed the elevator and rudder control cables today and although I don't seem to have the problem you mention, I noticed the elevator cable varies in tension as I move it through the normal range. The cables have less tension at neutral and tighten as I go up or down with the elevator. I am thinking it is just a matter of adjustment??

The program is way underutilized as most builders seem to let their egos get in the way. "By garn I built this thing so I can dern sure fly it" As the only flight advisor in our chapter, I have not been asked to help once even though we have had several planes finished and first flights accomplished inthe last year. Your flight advisor is there to help you evaluate your own skills, not for him to evaluate you as a pilot. He is also there to help you find the right kind of training if you decide you need it and to help you put together and execute a flight testing plan. - ------- Jeff Scott - Los Alamos, NM jscott.pilot@juno.com See N1213W construction and first flight at http://home.hiwaay.net~langford/kjefs.html & http: //www.thuntek.net/~jeb/krpage.htm _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

LOL Nope, haven't posted any pictures yet. After all, it's only been two years! Here's the latest progress report on the Phantom Eagle. I just finished refoaming the leading edge of the elevator and have half of it glassed. I mounted my aft spar with 2 degrees of incidence, will still use 1/2 degree at the wing tip (for a net decrease of a degree and a half of washout), and am working the horizontal stab mounting area to give me 2 degrees of negative incidence. These mods were incorporated based on the flight test data that Marty Roberts and Jean Veron collected when they swapped Jean's wings (Diehl wings) onto Marty's airplane (normally flies with plans-built wings). I did some more machining on my control stick to accomodate the 15 wire cable that goes to my Infinity multifunction stick grip and trial mounted it to the forward spar. The airplane noises sound MUCH better with a stick in your hand! I have one layer of glass on each side of my seat, I expect I'll need 2 more layers on each side. I'm using quarter inch last-a-foam to make a bench seat, and then will use some type of thermal conforming foam for the seat cushions, haven't decided which type yet. I'm getting anxious to mount the horizontal stab, but I'm doing the "smart" thing and doing all the micro/sand/micro/sand/micro.... before it's mounted. I need to pull one of the heads on my Revmaster, I'm not happy with the sound of one of the valves. I guess that's about it right now.

The tension will not change if two things are true, that is, if the length of the elevator control horn is equal to the length of the attachment points on the stick, and if the control horn and the stick are parallel to each other. If either is not true, then the tension will probably be different through the range of motion. Other arrangements will give even tension, but these two are the simplest. - -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ------------------------------ Date: Sun, 12 Jul 1998 20:53:44 -0500 From: "Mark Langford" Subject: KR: RE: Control Stick Austin Clark wrote: > I just completed the elevator and rudder control cables today and although > I don't seem to have the problem you mention, I noticed the elevator cable > varies in tension as I move it through the normal range.

Iif your cables are adjusted such that your stick is parallel to your elevator bellcrank, and the pivot points of stick and elevator are equidistant from their respective cable mounting holes and centered, the cable tension should stay the same, since they are both traversing the same arcs. I've been playing that aileron cable game all day, except that I have wing tanks and can't mount the pulley way out on the wing attach fittings. But since my aileron bellcrank is 18" from the wingtip, I have a much longer distance over which to reduce that angle. Problem is that I'd have to cut a 2" long ellipse in my main spar gusset (just above the longeron) for cable clearance as the stick swings back and forth, and I'm not willing to make that compromise. So I painstakingly measured and installed a standard 3/4" fairlead 2" behind the spar and 1.125" up from the bottom of the spar. This results in an absolutely straight shot from stick to bellcrank (with elevator nuetral), without even installing a pulley! The only pulley I'll have will be a return (180 degree) pulley mounted almost at the wingtip to complete the aileron loop. All of this is mounted to the back of the front spar, reducing cable length and number of pullies over the standard design. I now have a mandate to design stick number two , unless Bobby elaborates on his scheme. There are also several in old newsletters and Bengelis books that I'll look at, but the stocker is a very poor design no matter how you're doing your aileron cables. Oops... now I've alienated the other half of the "it's a perfect design" community. The reality of the "pitch sensitivity" thing is as has been said, mostly a matter of aft CG location (zero static margin). Unfortunately some people build to the plans and assume the CG will work itself out without really paying it much attention. These are probably the ones you see for sale with 4 hours on them. Like they say, the KR2S has probably pretty much solved the problem, assuming you pay close attention to CG limits, and make an effort to minimize its "volatility".

If you are using the Rand center stick (as shown in the plans) and build your elevator horn as shown in the plans you will get this binding action when you move the stick back and forth. The distance from pivot on the horn and the stick are not the same and like Don said, it will bind. I made a second elevator horn and drilled the cable attach holes closer to pivot, and the binding action is much less sever.

Taxi! Email (repy) to cary@storm.ca or ve3ev@rac.ca Web page http://www.storm.ca/~cary/ KR2 area http://www.storm.ca/~cary/kr2.shtml Taxiing the KR2 is a real treat. I guess all of you have found that one by now, or will soon. My legs now operate my bicycle much better due to my having to "S" turn the KR just to see what I'm about to hit. Mind you, my toe brakes are angled too far forward to be of much use, but I will no longer ache when I stand on my toes to get wifey's salad spinner off the top shelf in the kitchen. I took my camera with me on my last excursion to the taxiway at Rockliffe yesterday, but thought all of you had already seen the top part of a cowl. I guess the best way to see it is to take a picture of the instrument panel, and paint everything around it primer grey. Thats what I see anyway. It must be exciting to go into some place like Bancroft Ontario where you can't see the runway until you are past it on left base. (Right base takes you through the middle of a mountain. Not recommended approach technique) Imagine: you can't see the runway because of a mountain. On final, you can only see mountains. Pucker point = 100%. One added benefit to taxiing the KR for those of you who plan to do it without wings, is the mirth it generates within the local flying community. After my last taxi test, I went to the pumps to put my second tank of gas into it. On walking to the clubhouse, the club manager, who is also ATR rated, yelled the following: "When you taxi in a crosswind, you should do it with the ailerons to the wind." I must be dumb because it took me a few seconds to figure that one out. I also get comments like "How fast do you have to go to get it off the ground?" With the wing stubs only? Probably mach-2. The final humiliation happened while I was seated in the cockpit with the canopy up. Two girls, aged about 10 or so, came over and asked me what type of aircraft the KR was. I told them, forgetting the absent wings. One girl said she was impressed that the bird would actually fly with so short a wingspan. The other girl looked at the first one and said "Its not a real airplane silly, Its a toy. Just like you see it those parades with those guys who look like Arabs driving them."

I think that I have a pretty good understanding of what "KRNETTERS" are looking for in a Weight and Balance KR program. IM currently playing with the idea of adding several features to the program like a "visual" picture of where the CG and Arms are located on a virtual KR, "Loading Graphs" for displaying of information, etc. If anyone has any ideas of what they would like to see in a KR "Weight & Balance" software program, now is the time to say it... If everything goes well, I will bring copies of the "Beta Version" to the East Coast Gathering for free distribution(It will always be free, though). IM hoping that maybe this will be an added "incentive" for Builders/Flyers to come to the East Coast Gathering.
