Found a KR-1 there today. However it was not flown on. As I walked into the FAA pavilion, I looked up to the right and there it was. Inside the pavilion and mounted high and proud. KR-1 was on top of the tail and Ken Rand name was painted just below the canopy. Sure wish I could have touched it and gotten a close up look but it was high and dry from the crowd. Still did not see any that were flown in.

This was my first flight into OSH and was something to remember. A hint if you are flying in, know the procedures inside and out before you go. You do not need to have your head inside the cockpit at any point from twenty miles outside Ripon to shutdown. Know you power settings to achieve 90 knots and verse yourself on holding patterns. Let's put it into perspective, myself and my copilot (1800 hrs, CFII, MEI) turned the video camera on and laid it on the back shelf 30 miles outside of Ripon which is about 20 out of OSH and switched to the right tank which was full. We had 45 minutes of film left and figured to video our arrival into OSH. Four 360's for separation, two holds and 17 gallons of fuel later we shut down. The tape ended as we were entering our second hold over Fisk...........17 gallons of fuel to go 50 miles.................. Go to Avweb to listen to the controllers. Ripon is the initial fix with Fisk the inbound fix. You follow the railroad tracks from Ripon to Fisk and then get released to OSH. Now with that said, if you are worried about flying in forget it. Know the procedures and go to it, it is an experience you will never forget. The controllers are fantastic and baby when they say rock your wings, they mean ROCK YOUR WINGS:-). The show was great. The wing forum was far beyond my expectations. Chairs had to be borrowed from other forum areas to accommodate everyone. Many educated questions were asked and the EAA people were apparently quite amazed what the early KRNet was able to accomplish in the development and testing of a wing on such a large scale. Like Mark said, we had a small get together in the "South 40" Weds. evening. We however woke up Thursday morning with two "sodas" left and some kind of brown liquid in a glass bottle................I don't remember much about that stuff:-). Once again though, no KRs to be found:-( The ride out was pretty much of a non event. We filed IFR and while most others were grounded, we punched up into the soup and popped out at about 7000', climbed to 9000', dodged some thunderboomers around Chicago and generally just played around amongst the cloud tops, slicing, poking and skipping our way on the "magic carpet" home. Had a great time, am refueled by the spirit of the pilot "holy land" and it's mesmerizing spiritualness..................................oh, heck better get going and cut the grass................

I finally have gotten out to the shop and done some work! I melted some more lead and made what I hope is my last aileron counterweight. I've got about two days of work to finish the last aileron installation. I'm changing jobs! I decided I traveled too much to ever complete the KR, so I am getting a job that doesn't require that I travel... this means more time to work on the KR (I hope). I have a week off in between jobs in August, so I hope to do some KR work and possibly IFR training. I finally got the ELT bracket installed. Sometimes you just stand around worrying that your going to hose something up, instead of just jumping in and doing the work. After that I decided to finally drill the holes in the fuselage and cut the wing for the flap brackets. I have both the inboard brackets installed, and the outboard flap brackets are positioned where I believe they need to go... just four holes to go and I can look at the linkage installation. (The pushrods were fabricated years ago... now I get to see if there is interference from aileron crossover cables or fuel lines... I think I have a fuel line situation on one side.) For the new builders.... you might be ahead if you build the brackets, and position the flap spar BEFORE you do the foaming and glassing. I think I saw somone do this on their website and I think it IS the way to go.... lots of access issues if you do it as the plans... hint. The plans really don't say when to build the flaps. (Oh by the way... mentioning flaps on KR-net usually has the effect of starting many threads about flaps-no/flaps, spoilers or belly boards... stay tuned) I charged my battery... to no avail... no juice... I was hoping to listen to Ground and possibly PHX sky harbor, made a shopping list... Battery is on it. I also installed new RUBBER gaskets to replace the cork gaskets for my wing fuel senders. These were sent to me by a fellow KR'netter who works at Mitchel Instruments where the capacitive fuel senders are manufactured. I've got a leaky drain plug to fix on one wing, and some re-thinking about my quick-disconect lines (they are too long and kink), but I think I will build a jig to position the wing in mounted attitude, so I can fuel leak test, and do fuel flow tests without having to rig the wing completely in position. (These are preliminary, I Will do fuel flow tests after rigging), I was getting NO flow through my two facet pumps, so I need to check them again before hooking the wings on again. It feels good to have done some "real" work on the bird. Although I have worked on it several times this year... I checked my builders log, and noted that the last log entry was 7/28/99... so I haven't been keeping great track of my hours in the last few years. However the page before, I noted that I needed to "install ELT", and finally... it is installed! I have to do some work on the remote panel switch (The ACK ELT has a panel mounted test/activate LED module), but I want to wait until I know all my fuel lines are working. BTW... Sky Smith called me, and mentioned updates for my Libiality and theft/casuality policy. I have a ground only 1Mil liability policy which was required by the airport when I had my plane hangared... I decied while I was at it I would insure for theft/damage to recover the cost of engine instruments and radios in case someone (like a hangar mate) hosed me up. At any rate, I am waiting on this years quote which will also include a quote for the flying addition to the policy should I want to be covered for taxi tests.... in the past the ground only coverage for 1Mil liability and 15K casuality was about $328 or so. Just in case folks are thinking about hangaring their project your locality may require the liability policy. I think this year it jumped to about $400, but that is probably due to my move to a "major metropolotian" area. -- Happy building!

I want somthing straight through with a side flange for hot air intake. If possible I would like a filter placed before the carb intake.... This is for an Ellison EFS-2 flange mount.... it is an SAE mount (possibly SAE-2?) but I don't have my Ellison manual so I can't get the dimensions at the moment. The hot air flange I'm using at the moment is 2-1/4" diameter... but could change if necessary. I'm going to look for hits on the web... -- Regards Ross ------------------------------ Date: Mon, 31 Jul 2000 13:40:37 +0200 (CEST) To: krnet@mailinglists.org From: =?iso-8859-1?q?Paolo=20Cavazzuti?= Subject: Polimeric materials for KR Message-ID: <20000731114037.25245.qmail@web1201.mail.yahoo.com> Hy guys! I've a question for you, sorry if it's too stupid... Is there any classification about polimeric materials? I mean: as for steel or others metals you can know what you're talking about sayng "4130" or others, I don't know anything similar with "polyhuretan foam" or "epoxy" etc. (R.R. plans don't mention any specific number, or factory, or non generic definition... for example foam: what weight x volume?). There are some factorys of polimeric materials near my city, but how can I buy something, or at least bring some informations, if I'm the first who doesn't know what I'm talking about? I'll appreciate everyone who will give me datailed info about his experience (despite my bad english!).

Message-ID: <002201bffae8$6da5c3c0$058aef9b@kobusdewet> Hi Guys Just a reminder to ensure your undercarriage down lock is positive and holds during hard landings. I just lost a good prop, the tips off my exhaust stubs, some paint off the lower engine cowling and a big dent in my ego. The approach was excellent but I flared marginally to high and thumped her on the centre line. Well the locks jumped up and the wheels folded. So make sure the locks hold. Even if you have to put in a positive lock over and above the spring locks.

Message-ID: I believe that I would fix the retract system before going to all of the trouble of replacing it, which includs cutting up and replacing sections of wing and or fuselage. There are several things you can do to retain the original retract system. The simplest being add another 'rat trap' spring to each lock. You can also bend up another heavier spring to replace the weak original ones. Bob Muse Sr. can help you on that one.

It comes off fast, then I use my palm sander with 100 grit for finishing. It has real small cells so you get a nice surface that doesnt dent easily. I kept the sides of the fuselage bowed instead of making them straight like it says in the plans, otherwise I would have hotwired the outside.

I am building a KR-2S > and have a lot of questions. Dean I built my KR-2 over ten years ago and went through the same thought process as you are now. I did extend my -2 several inches, but it is still several inches shorter than the stretch. If I were building a stretch today I would NOT deviate from the plans for several reasons. The pitch sensitivity problem is only a problem in the minds of the inexperienced KR pilot. In a matter of a couple of hours you will wonder why all planes aren't this responsive. In my opinion the disadvantages of deviating from the plans far outweigh the advantages. Every time you deviate from the plans two important things happen. First you are now in uncharted territory so you begin wonder if you made it strong enough and if it will have any other unknown effects. Most builders make it stronger (heavier) and loose a little confidence in the project. The more you deviate from the plans the more confidence you loose and the less likely you ever finish the project. I have found it takes me at least four times longer to re-engineer and build the change. After the change is accomplished you find that the pre-fabricated parts like the turtledeck will not fit without extensive modification. (More time lost more confidence lost) Each change makes the project heavier and performance will suffer if the project is ever completed. I once herd that only about one homebuilt in ten are completed by the original builder and I believe that deviating from the plans is very high on the list of causes for these poor numbers. All the things I tried to improve (wider cockpit, more leg room, more canopy room, longer lever arm) have already been incorporated into the stretch design. I wouldn't change a thing. I still fly my KR-2 regularly and still make changes, but now all changes must satisfy two criteria. The change must improve performance or reliability, without adding any weight. By the way I am also planning a corvair installation. Keep a eye on E-bay for an engine, but check out the seller carefully and make sure you know what you are bidding on. I have had good luck with a corvair parts seller named "Toad4frog". ------------------------------ Date: Mon, 31 Jul 2000 11:42:10 -0500 To: From: "Mark Langford" Subject: Re: KR> Pitch sensitivity Message-ID: <000d01bffb0e$45b35dc0$a5f780ce@300emachine> "Seifert, Richard E" wrote: >All the things I tried > to improve (wider cockpit, more leg room, more canopy room, longer lever > arm) have already been incorporated into the stretch design. I wouldn't > change a thing. Richard, Your points are well taken with regards to modifications requiring more time. I'd say that Don Reid and I are "poster children" for that cause. But one thing that begs to be changed is the cockpit width, which is the same on the KR2S as it was on the KR2, WAAAY too narrow! The one thing that should have been changed was left alone in the "redesign". In a recent Kitplanes article the KR2S was ranked dead last in cockpit width, and the one they measured had already been widened! While it is probably true that it'll take longer to build the plane, I can't imagine the dismay I'd have if I built a plane and discovered that me and my wife (both pretty skinny) wouldn't fit inside. The stock KRs that I've been in required the passenger to put his arm around the neck of the pilot. I'd rather have a little more room than that, personally, but that's just me. I would guess that the majority of builders make their own decks and canopy frames, so the extra width has no real disadvantage for them. And I've heard stories of folks trying to make the premolded parts fit their fuselages which just didn't match, so there's something to be said for building all your own parts anyway. At least they'll fit properly if they're built in place from scratch. And while you're at it, you can bend the fuselage sides so that the widest part is at your shoulders where you need it, rather than at your knees. Just my opinion, but then I have almost 3000 hours into my construction and I'm only 80% done, so take it for what it's worth. There are plenty more opinions at http://home.hiwaay.net/~langford/kopinion.html ...

The premolded stuff may be nice but its terribly over priced IMHO. My plane should have been done in 2 to 3 years but I am just flat lazy and uninterested right now. It will fly someday. One good thing about taking a year off from building is people have stopped asking me if it is done yet. That was really starting to bug me. It was almost as if they had a deadline for me to meet. I also agree with Mark L, the one thing that needed addressing in the plans revision was the width of the KR2S.

As one of the poster children, I agree completely with Mark's assessment. If you are scratch building, make it wider in the shoulder area. I added some width, and it should have been more. I have well over 3500 hours in mine, and it would have been that much if I were building exactly to plans. I am a perfectionist builder. I throw out or re-do lots of parts without any hesitation. That is the reason that mine is taking so long.
