KR> KR performance numbers
Larry, When I had my KR-1 (around 400# e.w.), I came pretty close to the takeoff and landing performance as advertised (1700 cc VW), but certainly not anywhere close to 180 mph cruise (125-135 cruise). Ed Janssen Along the same lines, I sure wish someone would fess up and give the "REAL" performance numbers in advertising the KR aircraft. Takeoff in 350 feet, land in 650 feet, 180 mph cruise, really? Really.??? I've been to 25 of the last 26 KR Gatherings and have yet to witness such awesome performance. Larry Flesner

KR> Kr Bargain on Barnstormers
The paint scheme on the tip of the right wing in the picture matches that on the wing of a modified KR-1 built by Jerry Boggs. It was powered by a GO-145 Lycoming and was first flown in June , 1979. Although the fuselage hanging from the rafter is a different color (white?) it sure looks like the same one. The plane was featured on pages 46-48 in Sport Aviation, 1980.

KR> taxi testing
I did 9 hours of taxiing before flying my KR-1 for the first time. I learned a lot about directional control while fast taxiing. Wear light footwear - not hiking shoes. Use very smooth and slow throttle (and rudder) adjustments. For my first flight, I did the same thing as I did when fast taxiing. In calm wind conditions, I eased the throttle in - just enough to get the tail up - then when everything felt stable, I gave it a tad bit more throttle and very slight back pressure on the stick and off we went. I added full throttle just after leaving the ground. My first landing was my best. On final, I held 15-1800 rpm all the way to the numbers, then gradually came back on the throttle for a nice touchdown.

KR> Steve(s)
Steve's original KR-1 had at least three different owners that I know of after he sold it (I was the first one) before being destroyed by the last one. Briefly, as I remember, he was fast taxiing, reportedly not realizing he was holding full aft stick, it suddenly leaped into the air to about 50 feet, he then over-corrected and hit the runway. I don't believe he was injured. I think he was about as unfamiliar with the KR as anyone could be. He even told me that he believed it had a "Rotax" engine in it. He reported that it was taken to another location off-airport by a friend, dismantled, and cut up - the pieces were "used in some other project" - who knows what. If you do an NTSB search, you may find a description of the incident - can't remember the year. A couple of the attached pictures shows Steve demonstrating "level flight" to a potential buyer. The last two pictures are of the airplane when I owned it. Ed Janssen From: Flesner via KRnet A quick check of the FAA registry indicates the airplane may still be alive and well in Arkansas. It's registration was just cancelled recently. If so it ought to go the EAA museum as one of the first KR's, built in 1977. Larry Flesner -- next part -- A non-text attachment was scrubbed...

KR> flaps v belly board
Huh? I really can't be convinced of that. The force of the air hitting the top of the gurney flap is a force downward on the back of the car - very little, if any, differential pressure is causing any significant downward force. It's like saying that the shape of an airplane wing causes a "vacuum" of sorts on the upper surface, causing significant lift to make an airplane fly. Sticking your hand out the window of a car while it's moving, and "flying" your hand in the wind is evidence of that. The angle of incidence, relative to the wind, causes the wing to be pushed up from underneath. Ed Nerobro wrote, You're putting a huge air dam under the plane. This is essentially the same as a gurney flap on the back of a stock car. While the flap itself isn't making downforce on the car, it's making the air under the wing, and quite a distance out to either side of the flap pack up, and provide greater differential pressure.
KR> Maneuvers
Netters, For you relatively new KR fans: Still on the web is Bill Reents's KR-1 along with his many adventures and pictures of his and many other KR-1 projects. The home page has a picture of his plane in inverted flight. Search for "Bill's KR Aviation Homepage" Ed Janssen Mike Ladigo wrote: Pierre, I'm usually on the sidelines reading these posts, however on this one I have first hand knowledge. The KR does great aileron rolls. I have also paused for a few seconds inverted and there were no adverse flight habits. I wouldn't fly extended inverted as the airfoil is not symetrical and doesn't fly inverted all that well.
KR> Post curing wings
Yes, there may be some builders out there that don't realize that T-88 can be softened (with careful use of a heat gun) just enough to gingerly pry a glue joint apart without damage to the wood.

KR> Fly In
Dan, Yes, Paul Poberezny started the SAA (Sport Aviation Association) sometime around 1999, I think, and published a magazine called "To Fly". His friend, Rudy Frasca, close friend of Poberezny's, offered his airport, Frasca Field, Urbana, IL, to hold Fly-Ins for the organization, a grass-roots aviation event. The organization didn't last but a few years, perhaps due to inadequate funding. Even though SAA folded, Rudy offered to continue having a fly-in around the 2nd weekend in June. He (actually his son) has continued to send letters of invitation to former members each year since. Last year, I believe, it was held June 11th and 12th. Rudy has a very interesting small museum of airplanes, engines, etc. on the field as well as a modern factory that makes simulators. He usually offers tours of the factory during the Fly-In. One year Mark Langford and Mark Jones flew their KRs to the fly-in and gave a short seminar on KR building. William Wynne was also there at least one year to give a seminar on Corvair engines.

KR> KR incident minor
Louis stopped overnight at my home airport KSQI (Whiteside County Airport, Rock Falls, IL) on the way to OSH many years ago.

KR> Constructing fuel lines
I think this may have been stated before, but if you are a KRnetter that doesn?t monitor the Corvair list as well, you may be missing a lot of excellent reading, applicable to your KR building as well. William Wynne did an excellent job of posting a post-accident report of a recent CH750 accident. The following paragraph was taken from the report: ?A very important consideration looking at this photo: This is visual evidence of why you never want to use a hard aluminum line on the floorboard of an aircraft. The rubber hose that came with the kit was utilized to run from the fuel valve to the firewall pass-through. In several places it was pinched very tight between the distorted sheet-metal. Had it been a standard piece of 5052 aluminum tubing, I am sure it would have ruptured. If there had been fuel in the tanks in an accident where the aircraft remained upright, this leak would have poured fuel into the damaged cockpit. It is far more desirable to have a flexible line, preferably a braided steel one, in this location where a distorted floor from an accident would rupture a rigid line?. Quite a few KRs have aluminum tubing carrying fuel near or on the floorboard. If you are at this particular building stage, it?s worthy of consideration. Ed J.

KR> Advice Needed from Experienced KR Flyers
Several years prior to my first flight in my KR-1, I accumulated about 75 hours in a T?Craft. I did almost exactly as Mark, except that I logged a little over 9 hours of taxi time on my KR-1 on a 6500 X 150 foot runway. The first time I flew it, I used the same routine as when fast taxiing, said a quick prayer, then gradually gave it some more throttle and very, very slight back pressure on the stick ? and I was flying. In retrospect, I think I spent almost too much time over-preparing myself because it was absolutely nothing to fly it after all that ground training. Ed J. I think I had about 15 hours of tailwind time (mostly in a Champ) when I flew my plane for the first time. I'd have made a pretty good landing if I hadn't cut the throttle all the way back and "dropped it in" from about 5' up. I did about 60 runs up and down a 5000' runway to get the feel of the ground handling of a KR in the few days prior to first flight though, and I think that helped a lot. Mark Langford

KR> Engine for the KR-1
If we're still talking about VW engines for the KR-1 - As I remember, Steve Bennett started out with a 1600cc on his original KR-1. He described the performance as "marginal". He eventually upgraded to an 1835cc, I believe, with about a 9.1:1 compression ratio (requiring 100LL) which gave him much better performance. I was privileged to fly it for about 50 hours or so and it flew very well and seemed to have plenty of power for me. I also had about 50 hours flying a different KR-1 with a 1700cc VW (simpler conversion from a 1600cc) which also seemed to have adequate power. Ed Janssen

KR> fuel system fittings
Dean, I wouldn't be afraid of using barbed fuel fittings and for that matter plastic fuel lines, depending on the application. They are widely used in Ultralight, Light Sport Aircraft, and many Experimental-Amateur Builts in the US. There are some excellent (tough) plastic fuel lines on the market these days. Many builders, if not most, use safety wire instead of the worm gear type clamps which have been known to break or become loose over time. In Krs, such plastic lines have been used successfully (mostly aft of the firewall) for sight gauges, auxiliary fuel tanks, conduit for wires, etc. Some common sense needs to be used in considering placement away from a high heat source and in bend radiuses so they don't pinch off. Where fuel lines are visible, it's comforting to be able to see fuel flowing through them. I use clear plastic lines on my Minimax which can be inexpensively replaced every couple years as a part of routine maintenance. They can also help reduce the possibility of restricted fuel flow by reducing the number of fittings used in the fuel system and the flexibility can help absorb engine vibration.

Daniel, Depending on how large the area is to repair, it might be easier to form the trailing edge with thickened epoxy (flox) alone, using a straight edge, but if you use shaped aluminum, you could drill a bunch of little holes in the aluminum and epoxy (flox) the aluminum to the trailing edge and allow the epoxy to squeeze through the holes. Then, as Ken Rand use to "technically" describe precedures in his plans book - "fit and fair" the trailing edge. :o) Ed J. - Original Message - From: "Daniel Root"To: "KRnet" Sent: Tuesday, March 30, 2010 11:09 AM Subject: KR> delamination repairs I've been thinking about my trailing edge delamination issue.

KR> APRS
This alternative is a good idea for the present, but someday soon (we hear) the FAA will outlaw any 121.5 transmitter and instead require a 408.0 alone in it's place. Of course the FAA has only extended the present rules to allow both/either for a short period (?) of time. I believe that 408.0 is required in any other country outside of the United States now. I also read that the non-certified ACK model ELT 121.5 will soon have an inter-changeable module that transmits 408.0 instead of 121.5. When that occurs I would expect that the prices on the rest of the 408.0's will drop a bunch. While I doubt that the Fed's will ever let us substitute the GPS transmitter as a stand-alone to take the place of their required 408.0 transmitter, the APRS surely would make flying safer - and a lot more fun. Ed J. Mark L. wrote: One alternative to buying a new 408 MHz ELT is an APRS (plus your old ELT to keep you legal). The Automatic Position Reporting System is a ham transmitter/GPS combination that is mounted in your plane, and sends signals to the internet, which are then plotted realtime to Google Maps and Google Earth. Some of them have two switchable configurations, and you can set the second configuration to broadcast "emergency messages" which are automatically monitored across the world. When you go down a bunch of people know it almost immediately. Even if you didn't flip the switch before you went down, it wouldn't take long to find your last known position, which will likely be very close to your last transmission (depending on your location). The beauty of this system is that your plane and ELT can be ripped to pieces, but finding you (or your remains) would be dirt simple.
KR> Interesting flight
On a road? - sure you could. :o) Reminds me of the time when my Piper Colt needed an annual and the little town (about 1000 pop.) that the A (an old cropduster from way back) lived in didn't have an airport. So he said "just land on the road there, north of town. I'll park my truck at the top of the hill to block any traffic that might come along". Huh?? Gee, I never did that before, I said - I wondered about the local police, but he said they "wouldn't care - just be careful taxiing over the railroad tracks". So, I gave it a shot - had to dodge a few tree branches overhanging the road as I taxied through downtown to the delight of a few gawkers, but no other problems. We did the annual, I taxied back through town and took off from the road, circled once, and headed home. Ed Janssen NetHeads, I hit 850 hours on the plane today flying down to Hickory Mississippi to visit Gene Knight and see his project. More on that later, but the interesting thing was that I've always wondered if I could land on a road, and now I know I can. See http://home.hiwaay.net/~langford/flights/10020711m.jpg for a more detailed look, and note that the Interstate is wider than the 16' wide runway!

Scarfing in wood longeron pieces is pretty easy and plywood can be replaced. I would think that spars could be repaired as well, by scarfing in new wood as needed.

KR> For what it's worth about certifying
I talked with a CFI who has a bit of inside knowledge about how some FSDOs work regarding certifying a plane that you did not build. Here's what he wrote to me: "It may be a little white lie by the regulations, but it goes on all the time. Of all the kits that have been sold, I recall that there is approximately 75% that are never completed by the original purchaser, and resold to another builder. I know of one kit that has been completed to approximately 90% and has been resold 5 times. Those aircraft will probably be completed some day and will be certified to the last buyer. When (name withheld) was here at this FISDO (sic) he told me to de-certify my plane which is certified for a gross weight of 1250 lbs. and rename it, re-serial number it, find the right DAR and then have it re-certified at 1320 lbs. As long as you have the original Bill of Sale of the kit, or a Bill of Sale from a former owner that shows selling you parts and not a complete airplane, along with pictures and a builders log, then normally there should be no problem getting it certified with an airworthiness certificate." The key, it appears, is to find an FAA rep. (DAR, etc.) willing to go through the procedure. Ed J.

Dj, I'm not sure about that. If the major part of the work was done before being acquired by Dave, there could be a problem convincing the inspector that he should be included as one of the original builders. Dave should probably check with his local FSDO before proceeding. Different FSDOs have been known to interpret regulations differently.

If Dave completes the aircraft, he becomes one of the original builders and is allowed to apply for the airworthiness certificate, and also for the Repairman certificate. To be granted the Repairman certificate, he has to pass an "interview" with the FAA inspector basically showing that he can maintain the airplane in a safe manner. The EAA has information concerning this on their website. fyi -Dj

Dave, Currently the regulations say that if the purpose is to operate an amateur-built aircraft, then the experimental certificate is issued to the original builder, the person(s) who did the major portion of the work (interpreted to be 51%). See FAR 21.191(g): Experimental certificates are issued for the following purposes: (a) Research and development. Testing new aircraft design concepts, new aircraft equipment, new aircraft installations, new aircraft operating techniques, or new uses for aircraft. (b) Showing compliance with regulations. Conducting flight tests and other operations to show compliance with the airworthiness regulations including flights to show compliance for issuance of type and supplemental type certificates, flights to substantiate major design changes, and flights to show compliance with the function and reliability requirements of the regulations. (c) Crew training. Training of the applicant's flight crews. (d) Exhibition. Exhibiting the aircraft's flight capabilities, performance, or unusual characteristics at air shows, motion picture, television, and similar productions, and the maintenance of exhibition flight proficiency, including (for persons exhibiting aircraft) flying to and from such air shows and productions. (e) Air racing. Participating in air races, including (for such participants) practicing for such air races and flying to and from racing events. (f) Market surveys. Use of aircraft for purposes of conducting market surveys, sales demonstrations, and customer crew training only as provided in Sec. 21.195. (g) Operating amateur-built aircraft. Operating an aircraft the major portion of which has been fabricated and assembled by persons who undertook the construction project solely for their own education or recreation.

Maybe someone who has done this and found something that would work could chime in here. I've seen several 2-place Sonerai's that used an outboard motor tank as aux. tanks. If my memory serves, Steve B. had an aux tank built into a wing stub of his original KR-1 and then used a Koehler fuel pump to hand pump the gas to the header. Ed > >Lee Vann Dyke stated that he has to stop every 200 miles for fuel ue. >Mike Sylvester +++ Your can get 12.5 gallon in each outer wing panel with a tank that extends just 10 inches rear of the spar and runs the entire length of the wing panel. That keeps the fuel very close to the CG and with burn off the CG moves forward. Not a bad deal at all. How about a couple of aluminum tube tanks behind the spar and a smaller one on the front side?

***SPAM*** Re: KR> Re: Young Eagles Flights
Speaking mostly to non-choir members - unfortunately, the word "experimental" has an inherent negative connotation to anything associated with it - especially to the unknowing newspapers and the unknowing public who read and watch the news. There seems to be something sensational about being able to report a downed "experimental" aircraft as compared with simply "a small (standard) aircraft". That's one of the reasons why the Experimental Aircraft Association would rather be referred to as the "EAA". I remember at least one "Standard" aircraft fatal accident (Piper, I think) that got national attention involving a Young Eagles flight a few years ago and I can just imagine the difference in general public sentiment had it been an experimental. Sometimes we need to make personal decisions for the betterment of the whole - nothing wrong with that. Ed J.

KR> Certifieds
Mike, And, as long as you mentioned it, FAA regulations do not actually require any kind of instruments - flight or engine - for experimental category airplanes. However, builders would throw safety to the wind if they didn't. You would have a very difficult time finding an FAA (DAR or whomever) that would issue a Special Airworthiness Certificate to an experimental aircraft not having at least the basic instruments. For example, a compass is not required by the regs, but a DAR might require one before he issued a certificate. In such case, a compass from the aviation aisle of Walmart might get you by. Ed "Just a clarification for those suggesting that KR are not "certified" aircraft - KR aircraft ARE "certified" aircraft, just as Pipers, Cessnas, etc. are." Thanks for pointing that out Ed. I've been making the mistake of referring to the "other" aircraft as certifieds in various conversations, thus implying that Experimentals are not. It usually comes up in relation to conversations about what avionics & instruments can be installed . . . or not. Mike
KR> Young Eagles Flights
Just a clarification for those suggesting that KR are not "certified" aircraft - KR aircraft ARE "certified" aircraft, just as Pipers, Cessnas, etc. are. KRs are just placed in a different "category" - the "Experimental" Category with the purpose of "Operating Amateur-Built". Pipers, Cessnas and the like are certified aircraft placed in the "Standard" category. To generally imply that an experimental aircraft is necessarily less safe than a standard category airplane would be irresponsible.

I knew all that stuff Ed, but you were good to mention it because Dwight probably didn't. But what I was fishing for (I knew you were the guy to answer it) is how those same questions are answered with respect to LSA, since that seems to be important to him. I could look it all up, but I know you know it off the top of your head, and have melded several sources into the "real" answers. There are some nuances about LSA pilots flying Experimentals, so I'd think if you could license it as LSA to start with, you might be ahead. Again, I defer to Ed and others on that Thanks, Mark Langford Dwight, Well, unfortunately, neither the KR series nor the Sonex can be built and certified as an E-LSA - yet. Given the current manufacturer, it's pretty unlikely that a KR will ever be certified as a Light Sport Aircraft. If either manufacturer should successfully complete a rigorous process requiring jumping through a lot of hoops (paperwork and guidelines) and produces at least one aircraft eligible to be certified as a Special Light Sport Aircraft (S-LSA), then that manufacturer will be able to offer a kit which can be completed (51% rule does not apply) and certified as an Experimental Light Sport Aircraft (E-LSA). So, except for a few other options (not favorable for the type of flying we like to do), the only really viable option is to build and certify either aircraft as an Experimental Amateur Built (E-AB). Those with Sport pilot certificates may fly any aircraft that fits the definition of a Light Sport Aircraft (use your browser to find necessary characteristics). If the KR has been built and is demonstrated as fitting those parameters, a Sport Pilot may fly it. Hours needed to fly off the flight testing phases is typically 40 hours for Amateur built but whoever issues the "Operating Limitations" may require something different. Hours to fly off testing of E-LSA varies also - I've seen one Operating Limitation example showing only 5 hours needed. Ed
***SPAM*** Re: KR> I Need Some Advice From Flying KR'ers
Briefly, according to FAA regulations - If you build at least 51% of a KR2S per plans you may apply for certification as an E-AB (Experimental-Amateur Built). As the builder, you may then apply for a "Repaiman Certificate" for that specific plane. That will allow you to do an annual condition inspection on the plane without having to hire an A or other qualified individual. Anyone may work on, maintain, repair, etc. an airplane in the experimental category - no ratings required. > 8.

KR> Highest Time KR
Yes, Steve's original KR-1 had about 1500 hours on it before he sold it. It went through at least three owners after that. The first owner (me) put about 50 hours on it, the second owner (Indiana) didn't fly it, and then the 3rd one (around 1991) was doing some fast taxiing with full aft stick, in gusty conditions, when it suddenly leaped off the ground to about 50 feet, apparently stalled, and slammed back to the surface, doing major damage. That was at Blytheville Municipal Airport, Arkansas. It was reportedly towed to a local farm and dismantled. Supposedly, some of the parts were used in another project of some kind. The pilot was really unfamiliar with the KR-1 - even stating he thought the engine was a "Rotax". Go figure. Ed J. I just remembered Steve Bennett had put about 1500 hours by the time he sold it. That one, if it hadn't been crashed by the new owner, might have been the high timer? Mike

A couple of examples: picture an aileron bellcrank with a hollow core pivot point, if a spacer is inserted through that pivot point which allows the nylok to tighten up against the spacer, even though the bellcrank moves, the bolt/nylok combination does not. Another example would be an aileron pivot bracket mounted to a wing. Once again, if a spacer is used between the two flanges of the bracket, which allows the nylok to tighten down, it is acceptable.

KR> repairman's certificate
I've basically had the same experience with our Springfield, IL FSDO. They require an appointment to be made - and they usually review what paperwork and IDs you should bring along with you to the appointment. I didn't have to bring along any builder's log or pictures, probably because I already had an airworthiness certificate for my plane. Anyway, when you finally meet with them, they will go over all your paperwork and help you fill out a repairman application. They'll issue you a temporary repairman certificate right on the spot because it usually takes 2 to 3 months for your repairman card to be sent to you in the mail. The card will look very similar to the new style of card they use for pilot certificates. In my case, they issued me a new set of operating limitations to reflect recent changes in regulations and, surprisingly, also issued a new "amended" airworthiness certificate. I was told that both documents are normally issued at the same time and should have the same date on them.

I understand that I would have to almost start over on the licensing process as it has been 40 years since I have last been at the controls.

KR> Nuts and bolts
Pat, Regarding the cotter (not "carter") pin hole - fiberlock nuts should probably not be used with a bolt having a hole within the threaded portion. The thought is that the sharp edge or a burr around the hole could damage the locking ability of the fiberlock, especially if the nut has been removed and put back on several times.

KR> Re: Night flying?
Todd, Yes, well, I guess you could argue that it could be just as painful. Some will argue that the "experimental" nature of the KR, or any other experimental, will increase the degree of probability of having an engine-out/forced landing sometime in your flying career. I've had one in a standard category aircraft and I continue to expect another (although I certainly hope not) while flying the experimental I currently built and own. Some very careful and extremely skillful builders of Kris (Mark Langford and Mark Jones are good examples) have experienced them. Flying at night? Although you should be able to land a KR at a slower speed than a Bonanza or Mooney, it just ups the ante a little when it's more difficult to select a good spot to land. It's already risky to some degree just living day to day. You have to decide for yourself if you're willing to leave your rocking chair and accept an additional risk associated with any sport you love participating in. Ed Janssen And I'm sorry, but I'm not sure I understood the comments about night flight. Was everyone reluctant to fly at night period? I can't see what the difference between having to do a forced landing in a KR2 vs. any other aerial platform at night. It's going to be just as painful to have an engine failure at night in a Bonanza or Mooney as in a KR2 isn't it? Todd Thelin Spanaway, WA

KR> It depends
Dan, Not necessarily I would think. FPL-16A has been around a long time and used quite a bit back in the early KR years by a lot of builders (Steve Bennett was one of them). Guess it depends on what characteristics you're after. For the "newbies" - T-88 is awfully easy to work with, versatile (can be drilled and tapped, can fill fairly large gaps, can be thinned for sealing wood, is considered "structural" when mixed with cotton flox, etc.), and has almost become the "standard" with homebuilders, especially for wood to wood bonding. Ed So, is the bottom line, FPL 16A is the best adhesive for wood to wood? Daniel R. Heath - Lexington, SC
KR> Operating limitations
Netters: I applied for my Light Sport Inspection Rating today at the Springfield, IL, FSDO. They amended my original Experimental Operating Limitations in a few different areas. This one particular change may be of interest to you guys. Of course the required test hours are different for Experimental Amateur Built (such as KRs) than for Experimental Light Sport, but the other requirements are similar. "Flight testing required for phase 1 operations or as a result of the incorporation of a major change will be conducted in the assigned test area. Flight test operations will be conducted under VFR day conditions, with the pilot as the sole occupant of the aircraft. The aircraft must be operated for at least 5 hours in the assigned geographical area. Following the satisfactory completion of the required number of flight hours in the flight test area, the pilot must certify in the aircraft records that the aircraft has been shown to comply with Part 91.319(b) with a statement that includes the following information: I certify that the prescribed flight test hours have been completed and the aircraft is controllable throughout its normal range of speeds and throughout all maneuvers to be executed, has no hazardous operating characteristics or design features, and is safe for operation. The flight test was completed under the following conditions: maximum operating weight, style/set of wing or sail, maximum demonstrated airspeed, and minimum demonstrated stall speed. All major changes or modifications will be listed in the aircraft records and the compliance statement will be restated with the changes listed. The aircraft may not be operated in excess of the weights and speeds demonstrated." What is different about this is that the current operating limitations now being issued no longer require us to contact FSDO if we make a major change in our aircraft such as changing the engine to a different horsepower, using a different engine/prop combination, enlarging the vertical stabilizer, or any other modification that would result in a significant change in the flight characteristics of our plane. We just need to properly list the changes in the aircraft records. That being said, it's important that we review and comply with our own particular Operating Limitations, which may state something quite different than mine. But, it appears from my experience, that you could request an appointment with your FSDO to discuss and possibly request a change(s) to some parts of your operating limitations other than for obvious reasons like having to do with a move (change in geographical location). If you haven't looked at your operating limitations for a while, drag them out of the pouch (you DO keep them in your airplane, right?) and do a quick review. Finally, since the operating limitations and airworthiness certificate are integral, I was also issued a brand new airworthiness certificate to reflect the amendment to my operating limitations.

If you should sell your E-LSA, the new owner may do his own annual condition inspection provided he takes the appropriate steps (16 hour course, being one) to get a Repairman's Certificate with Inspection Rating.

Hi Nick; Re: KR> Snapped Longeron
Nick, I might mention, in case you don't know it, that you can separate parts that have been glued with T-88 by using a heat source such as a hairdryer. This works better for me than grinding or sanding one part from another. Use just enough heat to soften the glue and separate the parts. I have used a putty knife or screwdriver to poke into the joint to test when the glue is beginning to soften and then gently separate the pieces by prying, adding no more than just enough heat to do the job. Then it is fairly easy to sand the glue from the separated surfaces. You could make up a test joint to practice and see how much heat it takes.

Nick, My suggestion: It appears you would have enough room to glue a plywood doubler (same thickness as the skin) directly to the skin, extending a couple inches on either side of the scarf joint.

However, having said that, Mark Langford has actually done quite a bit of this sort of work on his own website. In the meantime, until someone steps up to the plate and wants to give it a try, probably the best thing for new or low time KR builders to do is to continue to search the archives, visit and study the best builder websites, and, as they come to mind, ask questions on the KRnet.

KR> sanding joints?
Most of us seem to accept this as gospel, but it seems to me that what little sanding "dust" is present, after brushing it off or vacuuming, should easily be soaked up by the T-88 and the resultant mixture would then be similar to a very light form of flox which is considered to be structural. Doesn't seem that the dust would effectively plug up the pores of the wood to the extent that the T-88 wouldn't eventually and successfully soak in to the wood. I can see where the accepted idea of roughing up the wood surface with coarse sandpaper is a good move because it increases the surface area for gluing. Has anyone made up some test pieces to prove or disprove? Ed Janssen > Sanding lets dust build up in the pores of the wood and > lessens glue penetration, Virg

KR> Question about airworthy certificate
Randy, I'm pretty sure your KR2 can't be re-certified. The FAA will probably not accept that you built a new plane either. However, at least changing retracts to fixed gear would be considered a major change which must be recorded in the maintenance log for the plane. I believe you would also be required to go through a 5 hour testing phase to prove the that the aircraft is controllable through normal flight maneuvers. You probably know this - since you didn't build the plane, you'll need to have the original builder or someone with the proper certificate (e.g. an A) to do the annual inspection. I'm sure someone will chime in here, if I'm wrong.

KR> N202RH sometimes they don't fly right out of the box
Rick, It appears, looking at your numbers, that your KR falls within the parameters of the definition of a "Light-Sport Aircraft" and therefore could be flown as such by the holder of a Sport Pilot certificate. The gray area of concern would be the KR design top speed which is greater than 138 mph.Of course, it can't be re-registered as an Experimental Light Sport Aircraft (ELSA), but must remain as an Amateur Built. Perhaps your stall speed and maximum speed was listed somewhere for the DAR at the time it was inspected? You may know of a DAR that could clear up that point for you.

E-LSA certification; Re: KR> N202RH sometimes they don't fly right out of the box
Rick, You may be right about not seeing a "grey" area. But, I think if I were just starting out building a new KR with the thought of making it LSA compliant, I would probably call it something other than a KR2 - maybe a "modified" KR2, or "whizz-bang special". You are incorrect about E-LSA being for "fat" ultralights (assuming you mean "only"?). There are quite a few plans built aircraft that have already been issued Special Airworthiness Certificates in the Light Sport category. Mine was certified near the end of 2005. As far as Amateur Built vs E-LSA positives and negatives, it's a matter of choice. A deciding factor with quite a few builders is, if they should sell their E-LSA, they can point out to the new owner that he (with a little training) will be able to do his own annual "condition inspection" whereas someone who purchases an Amateur Built will have to hire the original builder or an appropriately certified person (like an A) to do it. All said and done, Rick, I see no reason to believe that you can't eventally go with E-LSA certification. As Colin Rainey mentioned in another message, not all FSDOs at the present time are on the same page about this matter, which may cause you to have to search around a bit for the answer you like.

KR> Re: Maintenance on experimentals
Brian is correct, however not just the owner, but anyone can work on any experimental. Obviously, discretion should be used. I believe the reason is that there aren't many, if any, regulations governing working on experimentals. Also, the condition inspection is to be done annually, but really shouldn't be confused with the "annual", thought of prior to the Light Sport rules coming aboard. I guess it's all about semantics. Another common error - pilot "licenses" don't exist, only pilot certificates do. Ed Janssen mailto:ejans...@chipsnet.com > An owner can do all of the maintenance on an experimental.

KR> I NEED ALL PILOTS OPINION
I assume you'll be flying a nose-geared Cessna for your training. You'll need some tail dragger instruction before you're ready to fly your KR-2. Most pilots don't find the KR "hard" to fly - just somewhat different - which is why you need the instruction. It doesn't take a "long time" to learn. When you're ready to fly the KR, the best thing you can do is hop a ride (if you're the right size and weight) with a KR pilot in his KR. That should give you the necessary "feel" for a more control-sensitive airplane.

KR> "HELP" /FIBERGLASS CLOTH
Randy and Others, If you are just getting started working with fiberglass, "Fiberglass and Composite Materials" by Forbes Aird is a good reading source. It seems to cover most of the basic knowledge working with fiberglass, Kevlar, Carbon Fiber, different kinds of resins (polyester, vinylester, epoxies), health, safety, lay-ups, molds, etc. - and it is very easy reading. I see that Steve, at Great Plains, sells it for $16.95 plus shipping. Barnes and Noble and some others can probably find a used copy for you as well. Even if you've worked with these materials quite a bit, the historical aspect is interesting reading.

Some cloths have equal numbers of fibers running both directions, some have more numbers in one direction or the other. > > Biaxial cloth=two separate layers of unidirectional fibers running at 45 degrees to the selvage edges at 90 degrees to one another. These two layers are lightly stitched with crossing fibers just to hold the two layers in place. In the old days you had to lay down one layer of unidirectional cloth, wet it out with resin then lay down a second layer and wet it out. This fabric is great for covering wing surfaces because when you roll it off of a roll onto a wing the strands of fiberglass are already at two opposing 45 degree angles to the leading edge of a wing for example. > > Triaxial cloth=same as biaxial but has one layer of unidirectional strands parallel to selvage edge. > > Flox=is chopped up cotton fibers that can be mixed with already mixed resins to create a thick structural filler for making structural joints. > > Micro=micro spheres (glass balls is what I call them) mixed with already mixed resins to form a light weight filler (like bondo). > The fiberglass cloth is laid on the surface before the micro cures. (then add more pure resin to wet out cloth) > This is usually used to cover the foam surface, which is porous, before you lay fiberglass cloth on it. The reason for this is to save weight. You can use pure resin over foam surfaces but it will run down into the porous surface of the foam and make your part heavier. If you use the micro mix over the foam first it will fill the pores of the foam and save weight. You can use micro like you would use bondo to fill low areas that you want to level on a wing or fuselage surface. You can use micro to fill corners where you need to adjoin (for example) a wing rib to the spar. > > Wetting out cloth=I usually lay the cloth onto my parts then wet out with resin, but sometimes depending on the situation lay pieces of cloth on plastic and wet out with resin, then pick up the whole thing and lay it on the part, then peel off plastic.

KR> hiccupping
Just an historical note for the guys running VWs - Back in the "olden" KR days when most of us were running POSA carbs, we would get an occasional hiccup - usually at cruise speed - from the VW. The engine would keep on running, but it did make our hearts also skip a beat. Although there was a lot of speculation, I don't think anyone actually figured out for sure what was causing it, but it reportedly didn't happen with other forms of carburation. Maybe Jim Faughn has had this experience with his POSA setup.

KR> More Gathering 2006 pictures
Netters: Some more unedited Gathering 2006 pictures at the address below. By Thursday evening there were about 13 KRs on the field and another half dozen or so were added on Friday. So about 19 have showed up so far. Not a whole lot of flying went on today. We had a very light rain shower in the middle of the afternoon and most of the KRs were pushed into one of two large hangers. We'll see what develops tomorrow. For better viewing of the pictures, use the "slide show" button. It works pretty good. http://pg.photos.yahoo.com/ph/eros_62546/album?.dir=4b0bre2&.src=ph==&.done=http%3a//pg.photos.yahoo.com/ph/eros_62546/my_photos Ed Ed Janssen mailto:ejans...@chipsnet.com

KR> Quick T-88 question
I have some T-88, approx a year and a half old, that remains sticky to the touch on the surface, even after a couple weeks or more of curing.
