I emailed them and asked for a carb that fits a 172 cubic inch motor that was used on the 901. I will post the response here. Hey if you can get a NEW updraft card with mixture control that will work on your 200 - 300 cubic inch Cont. or Lyc for $200 why not give it a try? The Ellison solution is over $1000 and the new rebuilt Marvel is about the same. Not only that I have heard from more than one RV builder that the Ellison usually causes a loss in MAP. That sucks! Pay more money and get less horse power. What's up with that? __________________________________________________ Do You Yahoo!? Thousands of Stores. Millions of Products. All in one place. Yahoo!

I try to check (micrometer) each bit that I use in critical applications to see how close they are to the diam. of the bolt I'm using. I was surprised to find that bits do vary somewhat. If you snug up the bolts just barely enough to still allow you to move the spar, do you still get one inch - or something less? If you don't , I wouldn't be concerned as much. A KR-1 I used to own (I didn't build it) had a very slight bit of play as well - about that much or somewhat less. When I reattached the wings, I would lift up on the tip as I was tightening the bolts to proper torque. As a preflight check I always included lifting up the tips of the wings to see if I could detect movement. I never did. Would you have enough distance between a new bolt hole to edge of the material to allow redrilling the holes to the next bigger size? New WAFs is an expensive option but would be doable at your stage of construction.

These allow you to use standard plugs with a mag harness. So when you change plugs you pay $8 for a set of 4 plugs instead of $20 each. Steve says they have been tested on his KR for 50 hours and that in that plane there is actually less radio noise than with the shielded plugs. From Dec. 15 through Jan. 15 they are $79.95 for a set of 4 plugs and 4 adapters, instead of the regular $89.95. But that's the only time window that the special will be offered. http://www.greatplainsas.com Oscar Zuniga Medford, Oregon mailto: taildrags@hotmail.com website at http://www.geocities.com/taildrags/ ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com ---------------------------------------------------------------------- Subject: Re: Wing spar From: Mike Mims Date: Fri, 10 Dec 1999 07:25:42 -0800 X-Message-Number: 5 "Livingstone, Danny (DJ)" wrote: > I can lift the tip of the spar approximately 1" from the resting position until it locks up > against the bolt again.

The holes that were oversize were the AN3 holes (long bolts that go through spar cap). I could move the wing about an inch up and down about an inch at the tip. I replaced the WAFs with the good ones and now it is all one solid unit from tip to tip. If your play is at the main attach point (large bolts) I would buy a reamer and the appropriate size bolts. If the play is in the WAF at the AN3 bolts I don't know what to tell you but seriously think about replacing the ones that are loose. Personally I would not accept ANY play in the spars.

If you really want a KISS instalation, then you want air cooling. I say this with a smile, I just wanted to point out that water cooling is a lot harder to do than most people think. I think that very few people can challenge my experience on this issue. There are many good things about water engines, but simple instalation is not one of them. if you want a direct drive motor why not go to 2700 or 3200cc corvair? even a very simple and cheap Corvair will make 100hp at far lower rpm than your speaking of. Consider your goals and resources, and think about the Corvair, even if it isnt what you want, you should measure any other engine choice against it. And for further thought.... Weight has little to do with speed. this is a plane fact of aerodynamics. Go get a copy of "Aerodynamics for Naval Aviatiors" from the EAA and learn this.. Top speed of the plane is where drag = thrust, this drag is made of several factors like planform, intersection, and parasite, and last and very least induced drag. the only type of drag which weight has any effect on in induced, which tapers off to nothing as speed increases. THIS IS TRUE for all airplanes not just big ones or metal ones. The fastest homebuilt today is the Lancair 4. the fastest lancair 4 is jim rahms V8 powered plane. It won the great american air race to oshkosh last year in the unlimited catagory. I built this plane. I know what I am talking about. BTW Jim spent about $150,000 on perfecting his cooling system, not my Idea of KISS. thanks William ---------------------------------------------------------------------- Subject: Re: Wing spar From: KR2616TJ@aol.com Date: Fri, 10 Dec 1999 13:40:03 EST X-Message-Number: 7 In a message dated 12/10/99 10:31:54 AM Eastern Standard Time, mikemims@home.com writes: << Personally I would not accept ANY play in the spars.

I did have play in my original stamped WAFs and replaced them with their fittings. The difference was incredible. While I am plugging items, for those you thinking about using Cleveland brakes, go to the Great Plains website and check out Steve's new hydraulic brakes. I got the prototype setup from Steve. These things are great!!!! They cost less than Cleveland's, weight less and flat out work. You are going to be hard pressed (I don't think you can) to find a better setup.

We have had our disagreements on this list but I have to say, this is the best list I have ever been on. This post here is a post that was on the Mooney list. Is it any wonder.........they have their tails on backwards:-) I think the CMA stands for something else...............Certified Mooney Asshol#$%#$^#$%^& Dana Overall 2000 KR Gathering host Richmond, KY mailto:kr2616tj@aol.com http://www.geocities.com/CapeCanaveral/hangar/7085/ << Ross, I am an old salt from a generation that fought this country's wars over the past 50 years only to find that your generation is or maybe already has wasted what we thought we were fighting and dying for. Ross, you are what we would have called in the '40s and '50s a wimp; someone who falls on the school yard and wants to blame someone else for his skinned knee. You cry loud and long about your problems but do not have the guts to go solve your problems by looking your adversary in the eye and getting the problem behind you. Wars get started because people do not talk to each other. Put a 2x4 in the back of you fatigues and stand up straight- enough of the crying. I have been flying for several decades now and have over 2000 hours in Mooneys alone, so I joined this list to talk with other mature pilots about flying and not to listen to a bunch of back biting crap. To gain a better knowledge of you my friend, I called up all of your postings for the past two months in the archives. Ross you are making a fool out of yourself and your need my help!! 1. You obviously do not know the difference between a Mooney Service Center, an FAA repair Station, and an FBO maintenance facility when you think that you need to be a Mooney Service Center to sell and install an FAA issued STC. Do some research on these items. 2. You also obviously do not know what an FAA issued STC really is, how it is obtained, and what the purpose of the STC and the PMA required to manufacture the part authorized by the STC. Do some research on the STC process and find out what PMA means and how the FAA enforces the use of the PMA stamp. 3. You are obviously not familiar with the FARs and what limitations the FAA places on the owner doing any work, maintenance, or modification to a certificated aircraft when you talk about interest in owner installed de-icing equipment. Can not be done!!!! Read the FAR's so that you know what you can do and can not do. 4. You are obviously a low time Mooney pilot as your comments are not about maintaining and flying Mooneys but are attempts to ingratiate yourself with "way to go" and "nice job" type comments. I am sure that the older Mooney owners and pilots like myself do hit the delete key when we see "Rodom79@aol.com". 5. Finally, you are an embarrasement to me, and I would guess a large segment of the listing group, when you do not take the advice that Bumper gave you to quit the carping and the way you attacked the listing members when they disagreed with you by accusing them of taking a bribe to post their disagreement. Your professionalism needs some work. 6. Lastly, it is of grave concern to me that you are flying in my airspace. You have to be mature and have good judgement to fly in today's crowded skys and particular when flying IFR. I pray that I do not meet you in the clouds someday as that would be such a waste of almost 50 years of safe flying. Well, young man that is your fitness report. As always, I hope the recipients of my fitness reports learn from them and take them like men as constructive criticism. We wiil see how you respond. Contribute solid information to this listing and don't be a back slapper; learn form this listing and it's members but don't expose your stupid mistakes to the whole world; and then stand tall because you (not someone else) solved your own problems. This country needs now, more than ever before, more than just a "Few Good Men". By the way, those who are my close friends and Mooney pilots gave me the CMA and they know who I am. It stands for Certified Mooney Aviator!! Good Luck Ross!!!

The aircraft were fastened to tie downs with care, In the hope that come morning, they all would be there. The fuel trucks were nestled, all snug in their spots, While peak gusts from two-zero reached 39 knots. And I at the fuel desk, now finally caught up, Had just settled comfortably down on my butt. When over the radio, there arose such as clatter, I turned up the scanner to see what was the matter. A voice clearly heard over static and snow, Asked for clearance to land at the airport below. He barked out his transmission so lively and quick, I could have sworn that the call sign he used was "St. Nick". Away to the window I flew like a flash, Sure that it was only Horizon's late Dash. Then he called his position, and there could be no denial, "This is St. Nicholas One and I'm turning on final." When what to my wonder eyes should appear, A Rutan sleigh, and eight Rotax reindeer. He flew the approach on glide slopes he came, As he passed all fixes, he called them by name: "Now Ringo! Now Tolga! Now Trini and Bacun! On Comet! On Cupid!" What pills was he taking'? Those last couple of fixes left controllers confused, And they called down to the office to give me the news. The message they left was both urgent and dour: "When Santa lands, could he please call the tower?" He landed like silk, with the sled runners sparking, Then I heard "Exit at Charlie'" and "Taxi to parking." So up to the offices the coursers they flew, With loud airplane noise, and St. Nicholas, too. He stepped out of the sleigh, but before he could talk, I had run out to him with my best set of chocks. He was dressed all in fur, which was covered with frost And his beard was all blackened from reindeer exhaust. His breath smelled like peppermint, gone slightly stale, He smoked on a pipe, (but he didn't inhale). He had a broad faced and his armpits were smelly, And his boots were as black as a crop dusters belly. He was chubby and plump, a right jolly old fool, And he kindly informed me that he needed some fuel. A wink of his eye and a twist of toes, Led me to know he was desperate to powder his nose. I spoke not a word, but went straight to my work, And I filled up the sleigh, but I spilled like a jerk. He came out of the restroom with a sigh of relief, And then picked up a phone for a flight service brief. And I thought, as he silently scribed in his log, That with Rudolph, he could land in eight-mile fog. Next, he completed his preflight, from the front to the rear, Then he put on his headset, and I heard him yell "Clear!" And laying a finger on his push-to-talk, He called up the tower for his clearance and squawk. "Straight out on two-zero", the tower called forth, "and watch for a Cessna straight in from the North." But I heard him exclaim, 'ere he climbed in the night, "Happy Christmas to all, I have traffic in sight." - by Phyllis Moses (c/o Ken Brimmer) Larry Larry A.

It is part of my preflight to grab hold of the wingtip and shake it. If I noticed play, I would be hesitant to fly. On the subject of brakes, I have the Cleveland brakes and am not overly impressed by them. If I had it to do over- I would probably look at alternatives. They won't hold at full power run up.

(See attached sketch) >> <> >>Danny There should not ANY play in either spar. If you have any play or movement at the wing tip while lifting up and/or pushing down of the wingtip not due to motion from tires or gearlegs, then you have accident waiting to happen. Just because, you can lift up on the wingtips while tightening the wing attachment bolts to take out he movement, does not mean you have fixed the problem. Your KR will get g-forces in both directions in flight. All of the bolts should have snug-fit. The wing attachment bolts should predrilled(under-size) and then use a reamer for the final stage. We need is a PERFECT fit. This not optional. While I'm on this subject, I don't believe that it is wise to use spacers between the spar attachment fittings. Partly because it can be difficult to drill/ream thru both sets of fittings of each spar and keep a perfect fit. But also, by using a seperate bolt/nut at each of the eight(per side)attach points, you build in a safety factor in case of a single failure point. You should be able to attach your spars using the bolts without the nuts and get no movement at the spar tips. Remember, in shear loads/loading, as with the KR wing attach bolts, the nuts are there just to keep the bolts in place. But in flight the wing attach bolt will also have compression or tension loads placed upon them.

On the larger displacement engines the Ellison is VERY picky about how air enters it. I would say more than 50% of the pilots I have talked too with a Lycoming or a Continental fueled by an Ellison are un-happy with it. Most have reported a loss of max RPM as well as MAP at full throttle.

From: "Mark Langford" Date: Fri, 10 Dec 1999 21:36:24 -0600 X-Message-Number: 23 KRNetHeads, Indeed, the article is already at http://home.hiwaay.net/~langford/airfoil.html . I noticed that most of the URLs had been mistyped, with a dash replacing the tilde (~) in all of the URLs related to my site. Although I sent a floppy with both Word and .txt formats, it was obviously retyped from scratch, judging by some other errors I noticed. At least the www.krnet.org URL will work, and enterprising surfers can find the rest from there, I hope. He must have really been hurtin' for copy this month...

I just removed my second wing from the fuselage and freed up my parking space in the garage once again! My Corvair engine case, heads, and pistons are now at SC Performance getting the big-bore treatment, and I'm on a scavenger hunt for the few odd parts that I need to build my engine. I just bought another $100 Corvair engine, this one with two zero-timed heads, and in much better condition than the first. Now I'm basically down to instruments and engine, and the few thousand odds and ends required to get it in the air by my goal of attending the 2000 Gathering in September. See more details at http://home.hiwaay.net/~langford/kmarkl.html , below the usual stuff. It sure is nice to have a plane in this state where there are so many things to work on. When it's upside down (as it has been for over a year) there's not a whole lot you can do with it. I have this new attitude toward finishing up the plane. I used to think "ya know, I just wouldn't have time to finish that job tonight, so I won't even start it". Now, I think "ya know, I'll bet I can get that job done tonight, if I just get my butt in gear and do it"! And man have I been getting things done...

Mark good to see you back. I have to agree its pretty cool to have what is an "airplane" to work on. I spent a good 7 to 8 hours on my project today. Well at least 4 of them on my project. I made some cowling bumps for a Taylocraft F19 which took 3 hours or so. Anyway my plane is getting whiter and whiter! I am on my 4th coat of SmoothPrime UV with only 2 more to go and then its sand like crazy! The top of the right wing still needs some body work but for the most part the end to the filling and sanding is near. Keep working guys it will eventually turn into a airplane! :o) -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Sanding and Filling AGAIN! :o( http://www.fortunecity.com/marina/anchor/270/ mirror @ http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: grass landings From: "Lon Boothby" Date: Fri, 10 Dec 1999 22:21:23 X-Message-Number: 26 I am wondering if anyone has had experience with landing on a rough grass airstrip.

I had mine into a couple of grass strips in the midwest this summer. One of them wasn't any too smooth, but nothing nearly as rough as some of the stuff I used to fly my Champ in and out of. My KR has 5:00x5 tires, but the other KR that landed there with me had the smaller 11:00x4x5 "Lamb" tires that are considered to be stock on a KR. He flew in and out of there regularly.

I operated out of a 1300' grass strip. The grass was no problem, however 1300' was marginal for the KR-2 with a 1600 VW engine. I am now building a KR-2S and plan to operate it from the same strip. I am using a 2180 VW. also with flaps and the fixed gear with better brakes will be better than the retractable gear I had on the first one. About 75% done with the KR-2S. -----Original Message----- From: Lon Boothby To: KR-net users group Date: Saturday, December 11, 1999 12:22 AM Subject: [kr-net] grass landings >I am wondering if anyone has had experience with landing on a rough >grass airstrip. >I have been doing a lot of studying about the KRs and it seems like >the plane for me, but I have a rough grass strip and am wondering >if I will need to smooth it out a bit. >Thanks for your input, Lon > >--- >You are currently subscribed to kr-net as: molly@mhtc.net >To unsubscribe send a blank email to leave-kr-net-110995W@telelists.com > > ---------------------------------------------------------------------- Subject: Project Update - KR-2S From: apecorar@steelcase.com Date: Fri, 10 Dec 1999 23:21:3 X-Message-Number: 29 NetHeads, I've spent the last couple weeks doing some touch-up work on the frames for the rudder, elevator, and horizontal stabilizer. I also cut out the firewall spruce and made a template for the instrument panel. I am thinking about continuing the forward deck into the instrument panel so that it will be just one piece - I've seen this approach used by several builders when I visited their sites and I like the idea because I am not going to have a header tank. Anyhow, as far as assigning a percentage to the status of my project, I'm not too sure how to even do it. I've got the fuselage complete (cockpit varnished and insulated, floor installed, shear braces installed), 5 of 6 spar sections built (I have to build one more outer forward spar skeleton), rudder frame, horizontal stab. frame, elevator frame, rudder tailpost, vert. stab. tailpost and templates, WAF's cut and drilled, firewall spruce board cut. Is 10% a close estimate? ... Happy Building, Albert Pecoraro mailto:apecorar@steelcase.com P.S. - I'm out of town this weekend. If you reply direct I won't be reading my email until Monday.
