I'm widening 2 inches per side and moving the hinges in to 11.5 inches. Sound OK? I know... I haven't posted in a long time but life got very busy all of a sudden.

Friday, I went up for 1.3 hours in a 1940's vintage Cessna 140. No complaints but no sholder belts. You can tell the FBO's that are serious about taildragger training. In Phoenix, I flew a "like new" Piper Super cub, with the addition of a full sholder harness, and radio, Xponder. Fun. The two other FBO's charge big $$$ for "advanced" taildragger instruction, but the equipment is the typical beaten up taildragger. I'm not knocking them, they are FUN to fly, but for safety sake, I'd much rather do my ground loops in a plane with sholder harnesses than one without. King Schools called, and tried to sell me some more tapes, too bad I've bought all I can use for now until I decide to go commercial. So instead we chatted, and I ended up buying a book. "The Compleat[sic] Taildragger Pilot". I highly recommend this book! Covers all the stuff you need to pick up if you are transitioning (like me) into taildraggers. So far, my airwork is still sloppy, I still bounce around pitch wise in the C140 more than I would like, so I think the KR might be a bit much. I was chatting with a local EAA'er who owns a Arcoduster, and he said... want to go flying? Well, I couldn't think of a good excuse to say no. So at 10:30AM I took some personal time off and went up with him in his sky-rocket. I'd done loops before, but these were my first rolls. Fun! I even got a bit of stick time in the air, and did the pattern. There is NO over the nose visability in the Arcoduster, so it gave me a bit of a feel for what the KR could be like, however I think the KR visibility will be better (somewhat). I'm all pumped up now, I think I may work on installing my rudder pullys at the FWD spar (per Tech Counselor), and then fire up the engine, so I can taxi around the airport, and scare the natives! -- Regards Ross - -- Ross Youngblood Pager: (800)SKY-PAGE PIN#895-9073 Staff Technical Specialist voicemail: (800)538-6838 x 1632 Schlumberger SABER Bus Line: (541)714-1754 (Note Area code) Corvallis,Oregon Mailto:rossy@San-Jose.ate.slb.com ------------------------------ Date: Mon, 20 Apr 1998 14:07:50 -0700 From: Ross Youngblood Subject: KR: Loops/Rolls Actually I should correct my last email. I had done wing overs before, and probably a roll or too, but no loops. Loops are FUN! I think my next homebuilt aircraft will be Aerobatic, perhaps a Extra Klone, or a biplane. Talk about Roll Rate! We had done a couple of rolls, and I was flying the plane around when the pilot asks... "I guess I should have asked you about doing aerobatics without a parachute." I thought it was kind of interesting, and said, that we didn't do any rolls, so I guess it was OK, which is the point we decided to do some rolls. Looks like I am going to sign up for some Aerobatic training someday. Doing S-turns during taxi on a Arcoduster was a real treat. Did I say I was motivated? I'm Motivated.

Especially spins- so that you can get over the fear of them. I did my training in a Great Lakes (bipe)- with a chute on (Ross; I forwarded your post to the FAA enforcement div. ;o)- This bipe is very light in roll, and I mean light. As I recall, it was definitely fingertip flying. It would spin on a moment's notice, and fly as happily downside up as not. I really got a lot out of spin training, hammerheads, and all the rest. Also did some "carrier approaches" due to low/no vis over the cowling on final. Didn't do too bad; that's what you learn by soloing J-3 Cubs from the back seat. Also flew in a StarDuster Too; but exhaust gases into the cockpit during tailslides and messed-up hammerheads kinda got to me. The ground wobbled a bit when I got out. But definitely recommended training- if you can get it.

Holes in the center of the spar is important. You can get a looong drill and set up a jig and probably come close. An R/C servo in the elevator could work.

The hole has to be in the center of the spar if there's going to be a hole in the spar, but you can do it other ways. One of Tony Bingelis's books shows the cable in a little loop UNDER both the stabilizer and the elevator itself rather than through them. This sounds easier, but would have more drag.

Not to be to picky about details (Yeah, right!) but make that 125+ HP, not 225. It is an O-200, nameplate 100 HP at 2750 rpm. The higher RPM may produce up to about 140 HP.

The only concern that I see is that the turtleback is easier to build if the sides are straight. Drag would be lower if the sides bent in like on a Lanceair fuselage. The small amount of bend will not affect the structural strength. - -- 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: Tue, 21 Apr 1998 21:25:29 -0500 From: "Mark Langford" Subject: KR: KR2s for sale Got the new KR Newsletter today, and at the risk of copyright infringement, will pass on the following: For salde KR2 N250K.

Briefly, they are: #1 KR-1 has 450TTAF and 50SMOH, 1700 cc VW, Model A Ford carb., no electrics. This KR-1 is bone stock, as per plans - standard retract, etc. No show plane, but It flys absolutely flys great. Only four departure from the plans - a regular aircraft type built up engine mount (CG location much improved) instead of the aluminum channel, slick mag with direct drive to the crank (Monnett casting), positive pin locks for both up and down position, and heel brakes (mechanical). Sterba prop gives me approx. 135 mph at 3200 rpm and slightly over 3 gph. Airplane disassembled for repainting. Paint removal accomplished, surfaces need some smoothing before paint. Could use a new engine cowl but could wait as a Winter project if you want to fly this Spring. I have quite a bit of video footage (static and aerial). #2 KR-1 project has been advertised here before. Fuselage on standard retracts with new tires and mech. brakes, some controls installed. Hor. Stab. and elevator (with trim tab) glassed and ready for paint. Tinted canopy. Zero time 1700cc VW Monnett conversion, no mag or carb. I prefer to sell the whole shebang for a package price rather than part out everything. As some of you know, I'm sort of a KR history buff, so included are most all newsletters from #1 until the last year, several three ring binders chocked full of early pictures, articles, etc. on the KR-1 and KR-2, some extra instruments, antennas, and miscellaneous. I AM prepared to sacrifice. Best reasonable offer takes everything. I have approx. $6,000 original dollars invested. Reason for selling? I'm close to 60 yrs old, now have a 1290 ft farm strip and am considering an ultralight. I'm located central Illinois. Please, no tire kicking. E-mail me direct, please, with your questions.

Has it occurred to anyone that the elevator is almost as big as the stabilizer on the KR's and that all the pitch sensitivity issues brought up could be because the elevator control is just too darn effective for the stabilizer size? The KR stabilizer-elevator proportions resemble aerobatic planes, where you WANT extreme pitch changes. I plan to increase my stabilizer area 35% and DECREASE the elevator by 20% of its area. This will make the stab area about 70% of the total area, and the elevator the remaining 30%. What do you kit-bashers think? I'm not concerned with three-point or full-stall landings, so long as I still have enough elev authority on a flared wheel landing. I offer the Teenie Two as an example of a teeny tiny elevator. Control feedback pressures would probably decrease with this change, but stick movement-reaction would soften. Maybe some springs would help match it with the ailerons. The elevator does not have to be effective below the stall speed of the wing anyway, right? (About 43mph in ground effect.) - -Tom ------------------------------ Date: Wed, 22 Apr 1998 12:01:12 -0400 From: Tom Andersen Subject: KR: Removable elevator halves anyone?

An example of an airplane designed for the fool would be all the spam cans out there, with thick wings, stall warning horns that everyone ignores, and mushy controls. I guess the reason KR's could never be type certified is because they can't be made foolproof and still meet their design goals. The KR-2 is more pitch-sensitive than an F-86 fighter jet. I feel that by correcting that, I have improved the safety of the aircraft in normal CG operation.

The editor (Cox) of Sport Aviation conducted a long, taped interview with Tom and got personnal background information, construction info from top to bottom......looks a whole lot like an article is in the works. The chief photographer for Sport Aviation sch. an air to air photo shoot for this morning (Wed.) and if that did not take place (Tom left out early) he was going to come up to Tom's home in Gainesville and get the pictures. There were a couple of us who found out that they are looking to put a KR on the cover and believe me, Tom's is the real deal, oh by the way we finally told him about it. I talked with a judge at the poly fiber booth yesterday and he told me that Tom was in the running with ONE other plans built wood for tops and that they would judge until noon Weds. and announce winners Thurs. night but that he rated it high. I'm hoping they put the winners names on their internet page......I'll stick my neck out here........it beats the GP4 for first place. I've got some pictures of Tom's and the other KR and will post them on Thurs. and let everyone know. Great job Tom. Tom, I stopped in Gainesville about 10:15 but the flags were sticking straight out.

The engine is modified and they are running nitrous oxide! The announcement to the crowd over the PA during high speed passes was that the engine was producing "a horsepower exceeding 200". That is FAR beyond the normal rating of the engine. Aeroshell is intentionally pushing the envelope.

I did read about the NO injection for the time-to-climb records. Major power boost. In the air races, they can't use NO, just straight gasoline. I think in that case, the power will be more in the 140HP region. - -- 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: Thu, 23 Apr 1998 17:50:31 From: Austin Clark Subject: Re: KR: KR Sun & Fun.

I just posted pictures of Tom's KR, Dave Blucher's KR & George Huber's KR on my web page under Misc. I better take some pressure off Tom and say that Sport Aviation is looking for a KR for a cover shot but with that said boy, if they get a good air to air shot don't be surprised if N262TC graces the cover before the years out. The pictures don't do any of these planes justice but check them out there's a couple of good shots. It was great meeting all you KRnet guys down there, Tom, Dennis, Mr. "Go Packers", Pat Flowers, Ron Dewess (sp), Bruce Campbell, Tom Anderson, Ron Freiberger and as always one of my favorite people to talk too Mr. Muse, Sr. I know I'm leaving some out but there were a lot of us there. Guys it seems that the KR is in the midst of an resurgance here, the KR forum ended with probably 130+ there, Tom's KR was without a doubt one of the most photographed planes down there, there's of picture of this plane all over the place now. I can't tell you how many people stopped me because I had a KR shirt on just to talk about the plane. Believe me the KRs there did nothing but help the cause. Sorry for the rambling but we had a big time, great cookout by Steve B., good beer, good dogs, great KR dinner, everyone won something that was donated by the booths from a wiring harness, to "all right a key chain" :-)), I endup up with a bolt gauge, experimental placard from George Huber and a panel mount clock that I ended up giving to a builder from the Netherlands. Big time was had. Back to enlarging my trim tab. Ross just stay ahead of the tail.....easier said than done at first, huh.

Those 3 KR's look like they were some of the best examples of KR's that people could see. Do you have any more info on George Huber's KR? Kinda curious about his gear. Sorry that I missed Sun N Fun.

Is there anything wrong with making all the wider dimension? Since provision must be made for pressure differential on the box spar anyway, I can't see a problem with making the verticals wider. Seems that contact with both webs would give additional strength. Someone please straighten out my confusion on this. Thanks.

Brian J. Bland Claremore, OK >> George's KR is 24" longer than the plans with standard width. Les Palmer did all the metal work for the Subaru and the gear. Empty weight 886 lbs. turning a 60X67 prop. The gear is Les Palmers design but would be real easy to duplicate. It is a shock type system that simply uses three rubber bushings inside the larger tube to accomplish this. I really is a pretty simply design. He had some cooling problems so he moved the radiator to the front of the cowling, I'm wondering about it being a natural speed brake. He has not flown it yet, it is signed off but he trailored it to Sun & Fun. As far as coming to Sun & Fun, it's a lot more laid back, I even got tired of airplanes and left a day early, but it is a great time, good 85 degree weather, southern hospitality, and a short drive over to the gulf coast, or if you can hop a ride 15, 20 minute flight to be able to fly up the coast.
