I also had a high fuel pressure warning on the engine monitor, but my analog gauge indicated all was normal. That was tracked to a "protective" sleeve over the 4 wires from the transducer that got wet inside. As soon as I removed the sleeve, the fuel pressure readings returned to normal. The new radios were fogged over inside the display, as were my gyros, but all worked well and have since dried out. I spent this afternoon redesigning and replacing the weatherstrip seals on the canopy and the boot cowl access hatch, both of which leaked rather badly. The plane is in the hangar with the canopy open and a fan blowing air around the cockpit and up through the panel. I'll post some photos from the ride home on the FB site.

Re: KRnet> Ground loop Incident
It's been a few days since my ground loop incident, and I've had time to reflect on several things that In the interest of "lessons learned" I will add to my before takeoff checklist. Here is how I think I screwed up: I checked the AWOS at start-up as it's normal prior to taxing out to the ramp. I called ground and made the request for the option of a high-speed test, or a full takeoff and I finished my transmission with the phrase "with information Alpha". The tower cleared me to taxi to runway 36 via Alpha to the run-up and wait. They had several airplanes in the pattern and a jet on a long final. By the time I was allowed to get on the runway, a good 15 minutes or so had elapsed. I was there so long that I actually shut my engine off. I listened on my handheld for my clearance. In the span of those 15+ minutes or so, the winds had increased, and now more like a 90 deg crosswind gusting to 23kts from a milder 12kts. The only clue of higher winds was the airplane rocking once in a while, but I attributed that to two Citation Jets that were taking off and landing. At one time I tried to make an effort to look for the windsock but from my nose high position and where the nose was pointing, I could not see the windsock. Lesson learned: I edited my checklist to make it mandatory to recheck AWOS at run-up before to switching to the tower. This will assure me that I will be fully aware of my flight conditions prior to takeoff. Luis.

Re: KRnet> Happi gauge
I am having the same problem on my 2100D. I've had fluctuations on my Oil Pressure EMS indicator from a normal (temp) oil pressure of 30PSI dropping down to 12PSI which sets off bitching Betty. I connected a mechanical pressure gauge on a tee where the oil line comes off the engine, one branch of the tee goes to the VDO sending unit mounted on the firewall (braided SS line) and the gauge is mounted on the engine coming off of the engine case. This is only for testing purposes with the top cowling off.. The mechanical gauge has recorded pressures as high as 45-50 when the engine is cold and 23-30 when engine is at normal temperature (approx. 140deg F). On the contrary, I have recorded pressures as low as 12 PSI on the EMS during the same test. I have replaced my oil pressure sending unit three time. My latest one is a VDO unit. The other two previous units were bought on the internet from China. My oil line is a SS braided flex line from the engine to a header on the fire wall which connects to a test port for a mechanical gauge and a secondary port for my sending unit. I was wondering if the line has an air pocket in it that acts like a hydraulic hammer and causes the fluctuations. My second thought was to rebuild the oil pump. Sorry that at this time I have no solution, but I am working on the problem.

Buy an off the shelf gauge and see if it matches the direct reading test gauge. I can't imagine that it wouldn't.

If the builder has a record of the weight of the boat, you can then estimate the final weight- many KR2 and -S weights are published on the net, in a spreadsheet, I believe. These are airplanes, so heavier isn’t better-unless the gross is increased, in which case, you are entering theexperimental-experimental world. Are AN fittings present, or Home Depot bolts?

Re: KRnet> High impedance short - lessons learned
John and Larry, thank you for your input. I totally appreciate it, which is why I reach out to the group...First things first... I will explain what I know from my observations as a layman. Here is the trial-and-error method that I used to find the fault... 1. I removed all devices connected to the Avionics switch (lit with an LED indicator) which is the culprit.2. I disconnected the wire supplying power to that switch (the switch status is off) from the power buss. 3. Then turned the switch on 4. I touched the wire from the switch to the buss bar5. I observed an arc, and the wire became hot (as in heat).6. No breakers tripped though it was connected to a 5A breaker7. When I removed the wire from the buss, again a small arc followed. 8. While the switch was on, I observed the battery drain from a normal 12+ Volts to as low as 10.5V9. I removed the switch and replaced with a common toggle switch (rated at 10A)10. I reconnected the circuit to the buss, and I did not observe arching nor did the wires get hot.11. I kept feeling the wire for heat for a few minutes before reconnecting devices one at a time12. After I reconnected all devices, I turned them on one at a time to see if I still had a problem.13. All devices came back online without any problems14. The voltage as recorded by the EMS indicated a stable 12.5VDC with no deterioration. Today, I went out to the airport and ran the engine, turned on all of the instruments and between the battery and the alternator, I was able to sustain a steady 12.5VDC. I ran it for about 5 minutes and shut it down. I reached under the panel and all wires felt normal (no heated wires). I hope that helps some.

KRnet> High impedance short - lessons learned
For the last three months ore so, I’ve been battling a battery drain that has kept me grounded. Being that my electronic ignitions require a healthy 12V to operate, any drain below that affects both ignition and my transponder. The xponder is critical cause I fly under Bravo airspace. To the problem: As I taxi my airplane I noticed a rapid battery voltage drain from a normal 12.5V to a no go condition of 11 - 10.5v. I would taxi back , recharge the battery, do a battery drain and charging system test and find no faults. I then decided that I may have too small a wire feeding my main buss. I changed all feed wires from 20 ga. to 14ga with the main being 12ga. I fired it up and no improvement. My last desperate act was to disconnect every wire from the buss and reconnect one at a time to see the effect. The last wire I reconnected was my avionics switch and bingo, it arced and I got the voltage drain This switch has a built in LED which may have shorted and caused a high impedance drain without tripping its breaker. I replaced all switches to regular toggle switches and everything is back to normal. I can now return to my flight testing and planning for the meet. Luis R ClaudioN8981SDallas, Tx.

I'll just cut straight to the chase and announce to the KR world that I am the
new caretaker of N335KC, a KR 1-1/2. Upon seeing the gold-bronze anodized
spinner on the plane when I got it home, my daughter dubbed the airplane
"Sunbeam", so this post is about how I came to be the new caretaker of this
fine KR.
The plane was constructed by Ken Cottle in 1987, got its airworthiness
certificate in April of 1990, and is featured in the step-by-step instructional
video describing how Diehl premolded wing skins are installed on KR wings. It
was later owned by Steve Bennett of Great Plains Aircraft, when the engine was
changed to a Great Plains 2180 with a top-mounted Ellison. It's basically a
KR-1 that has been widened a bit but is still just a single-place. It may be
the only KR 1-1/2 in the FAA Registry (unlike the KR-25, of which there appear
to be many examples ;o)
Through my great fortune and occasionally making gentle inquiry to Mike
Stirewalt about the airplane, we recently came to an agreement about me
bringing the plane up here to my home field of KMFR in southern Oregon from his
home base at KSEE in southern California. In a whirlwind transport operation
August 1-4, the plane made the trip uneventfully and in very good weather to
have made the move on an open trailer. KR mover extraordinaire John Bouyea
made the move happen as smoothly and efficiently as it did, and the only
deviation that we made from "shortest route from Point A to Point B" was to
visit Joe Horvath at Revmaster in Hesperia the afternoon of Friday the 2nd on
our way south. Although Joe's people were almost all gone for the day by
lunchtime, he graciously kept the shop open till we got there. Some very
interesting things in development there, along with all of Revmaster's standard
offerings. We had a great time on the tour of Joe's shop, what with all the
shop machinery, engines, and interesting little parts and pieces everywhere.
Joe has some great stories, too... like the one about the 800HP VW.
We arrived at Mike's hangar Friday evening, spent all day Saturday loading and
securing 35KC onto the trailer with the wings on stands in the bed of the tow
vehicle, and Mike offered a running commentary on the airplane's systems and
operation as we worked. The man is a gold mine of aviation knowledge, and as
the plane's most recent caretaker and operator, he is the very best source of
specifics on its care and feeding. We departed the field late Saturday
afternoon, parked overnight in the Bakersfield area, and got to my hangar
Sunday afternoon to unload, inspect, and stow everything. John stayed in
Medford overnight and made it back to his home field up in Hillsboro on Monday
after putting 2,310 miles on his truck. Operation Sunbeam was a complete
success thanks to John's organization and skills as well as the use of his very
capable Ford F250 and flatbed trailer.
I still can't believe that I'm looking at a KR in my hangar as I get it cleaned
up, inspected, and understood. I have a Rand-Robinson info pack that dates
back to when I first got interested in the plane sometime around 1994-95...
some 30 years ago. To learn more about building and operating a KR, I found
out about the KRNet back when it was just transitioning from bulletin board
format, probably around 1997. Some of you may recognize names from back then:
Tom Crawford, Bobby Muse, Ross Youngblood, John Bryhan, Ron Lee, Randy Stein,
Robert Covington, Don Reid, Mike Mims... and so many more. One of my first
contacts with this group was when I became aware that Mark Langford was THE
builder who I wanted to emulate and learn from, and one of my first keeper
posts from the net is dated 10/12/97... from John Bouyea. I also met Jeff
Scott through the KRNet, and he has been a constant source of technical
information and engine smarts for me. I would have loved to be planning to fly
35KC to the Gathering this year but it's just not ready yet and neither am I.
I need to learn the plane first!
My eternal gratitude to Mike Stirewalt for so graciously launching me out on
this new adventure and for sharing this airplane and his knowledge with me. I
am equally grateful to John Bouyea for his tireless efforts, long hours and
miles on the road, gallons of sweat, and constant encouragement that I could do
this. I told him that he's very good at lighting matches... he had to light a
lot of little fires under me to keep Operation Sunbeam on track and across the
finish line. I also want to thank all of you on the Net for keeping this flame
alive for me all these years. The culmination will be when I get air under the
tires and get to take my first ride in a KR time machine!

Re: KRnet> KR high speed taxi test
In my honest opinion, high speed testing is a necessary part of any experimental airplane experience. I battled several issues with my airplane, and I found them by doing high speed testing. During this time, I was constantly talking to John Shaefer, Brad Nichols and other friends about issues and solutions... sometimes you HAVE TO reach out to your friends for help... 1. Engine Ignition: My Revmaster engine was driven by a Bendix DR3000 magneto. I had a lot of trouble getting this magneto to work correctly so I sent it out to Tulsa for overhaul and setting of the correct timing. The mag shop in Tulsa suggested that I not use this magneto since it was no longer supported but that they could go ahead and replace worn parts and return without certification. I then made the decision to go full electronic with an SDS system from Canada. That whole process of re-inventing the wheel took me several months of trial and error... during my high-speed testing I was satisfied that this solution was the correct solution, and it now powers my airplane. I will talk more about this at our meeting. 2. Prop: When I purchased my engine, the previous owner threw in a new prop. During testing I found that this prop would only give me 2800 Static RPM. I was looking for 3100 to 3200 RPM. I thought that my issue was carburation and not the prop. After several iterations of adjustments, needle changes and whatnot, I decided to call John Shaefer. After listening to my frustration, he suggested a change of prop and said that he had a 52X54 available. I purchased the prop and that seems to have solved the RPM issue... 3.Brake Pedals: Testing, I found that the brake pedals were poorly designed and bent under a heavy brake load. Upon braking, I found that instead of applying pressure to the brake cylinder, the pedals would bend and not stop the airplane. I had to redesign the pedals and after several iterations I found a workable solution using aluminum channels instead of thick flat plates. I purchased some used brake cylinders at an aircraft salvage yard in Dallas, I also purchased an overhaul kit from Spruce. In spite of the overhaul kit providing new internals, during testing, I found that the cylinders were bleeding through internally and not applying sufficient hydraulic pressure to stop the airplane. This issue almost cost me the airplane since it allowed me to wonder off the runway and into the grass several times. 4. Baffles: I had heating issues with the rear cylinders showing very high temperatures. I found that my baffles were not providing a tight pressure boundary thus allowing cooling to escape through gaps and ill fitted silicone seals. I just completed a complete overhaul of the baffles, and I seem to have corrected the issues. 4. My Revmaster engine has an Aero Injector, and It took me several weeks to get this injector dialed in properly where it would give me the RPM;s necessary for flight. This carb was my first experience with injector style carbs and setting it properly was a challenge. I purchased several injector needles to experiment with and still could not get it to run correctly. Part of the problem that I found during my trouble shooting and calibration was that during my engine assembly, I had been interrupted by a visitor at a crucial moment of assembly. I found the right intake manifold loose. The engine was sucking air through a gap caused by my mistake. I could not get the engine to idle correctly and spent many days disassembling and re-assembling a carb that in reality was working correctly. Once I fixed the problem the engine purred like a kitten. I wanted to enumerate all of these issues to show that when you think you are finished and ready to take to the air, it is wise to spend time on the ground running your engine and other systems to ensure that your aircraft is really ready to fly. There are many instances that I can think of, that if I would have taken off with one or more of these issues, I would not have had a very pleasant outcome. Additionally, I did not bow to the pressures of my local friends and visitors... I worked till I felt that I got it right. I now have 7 hours on the airplane and trying to fly every day to get this puppy ready for Mt Vernon. Presently I am doing time trials to get my airspeeds calibrated and practicing fuel transfers since I am planning on flying non-stop to Mt Vernon. I want to make sure I can transfer fuel from my aux tanks to the main header tank with no issues. I am pressed against the clock but weather permitting, I will finish my hours and aim the nose East...More to come...

KRnet> Chad Robertson - KR2 Builder
I am sorry to inform the group that I received a text from Chad Robertson's daughter informing me that he had passed away from cancer. Chad was in the process of building a KR2S in the Coffeeville Kansas area and had visited me this past 12th of August on his way to cancer treatment in Texas. His daughter told me that she and her sister were committed to finishing the airplane in his honor. One of the girls is taking flight training and wants to fly the airplane once it is completed.

Re: KRnet> Batteries, final thoughts
I agree John. It sure helps to know how to calculate battery needs... so when I apply the engine cubic centimeters to cubic inch calculator it will return the engine displacement value, such that: V = 4 * 250 * π * 50² / 4 = 1,963,495 mm³ = 119.82 Cu. In. So, using Larry's rule of thumb as 1 cu. in. = 1 CCA then X 119.82 = 120 CCA required plus 20% reserve = 144 CCA. Nice.

KRnet> 2023 Gathering - Our visit to the gathering
This past Thursday, Brad Nichols, Dr. Hsu, and I traveled to our 2023 KR Gathering at Mt Vernon, IL. This was Brad's first time attending and Dr. Hsu and I had three other gatherings under our belts. My home port is KHQZ and sits under Bravo airspace in Dallas. The weather was calling for 200 ft. ceilings and visibility of less than 1/4 mile with embedded thunderstorms until Saturday evening. Even if I had flown off the 40 hours off of my KR... there was no way to secure a VFR departure clearance, so the decision to join my two KR buddies driving to KMVN was an easy one to make. Brad drove to KHQZ from Navasota (2.5 hrs) and Dr. Hsu from the Johnson Space Center in Houston (3.5) hrs. While we waited, I gave Brad a tour of my now-finished KR and he asked a million questions and we talked about his project. It was in a way like a precursor to the upcoming gathering and the things we would see there. We arrived at Mount Vernon at 5 AM on Friday morning and almost froze to death in the 57-degree morning in Illinois. We had been living in Texas under 105 degrees days and 57 degrees felt like near Arctic conditions for us...We jumped back in the car and waited till the sun came up... During the meeting, we visited with pilots already flying their KRs and others who were still building... Brad in particular was able to actually look at and touch some of the airplanes on exhibit and talk to their builders/pilots. Dr. Hsu as always, mingled among the attendees and questioned everyone about topics that interest him the most. In general, I can attest to the fact that Brad walked away a much more confident builder. The exchange of ideas and information with the builders has given him the confidence to continue to move forward with his build. Brad and I talked ad nauseam about lessons learned and future plans for our airplanes. We missed flying up to KMVN this year, but God willing, we are fully committed to taking our steeds of wood and glass north to KMVN next year to be one of the pilots/builders showing off our work. That is a promise. Luis -- KRnet mailing list KRnet@list.krnet.org https://list.krnet.org/mailman/listinfo/krnet

Re: KRnet> Thanks for all the help ... For the assistance starting my KR2
Dee, I agree with Rob... I too, do not have a check valve, and fuel flow is dictated in the Posa Injector, by the opening of the mixture control lever. If you notice, the fuel entry to the injector is through the mixture valve. To properly set it, make sure that when the mixture is fully retarded (pulled back) the mixture valve is fully seated in the closed position, then while cranking to start the engine, advance the mixture control and fuel will start flowing to start the engine or likewise, crack the mixture valve when you are doing your initial 5 prop turns by hand as we discussed earlier for a quick engine start. To ensure that no fuel is flowing when securing your airplane at the end of your day, retard your mixture control and shut off your main tank fuel valve also. Just keep it simple.

Dee could you send me a PM with your phone number? I can explain my procedure for setting my mag timing and fuel set-up. Do you have a magneto tester? Thanks Luis R Claudio On Monday, May 29, 2023 at 06:35:30 AM CDT, Mark Langford wrote: I should also mention that there is only one firing order for a normal VW type 1 engine, and that's 1-4-3-2. For some reason, the GPASC manual has 1-4-3-2 for distributor ignition, and 1-2-3-4 for magneto. I have no idea what Steve was thinking when he put this in his manual, unless the magneto terminals and wires are numbered differently, but that simply doesn't change the firing order of the cylinders, and when they need a spark delivered for the engine to run. Bottom line is the cam and crankshaft determine proper firing order, and unless it's a very weird VW, it's 1-4-3-2 (and I know of none, other than maybe the "half VW"). So if you set up number one cylinder at Top Dead Center (TDC) on the compression stroke, with spark plug firing on number one, and then work through the rest (as previously mentioned) in the 1-4-3-2 order. Rotate 180 degrees and check the next, etc. Obviously, you need to mark TDC on the spinner backplate or somewhere else visible, so it's easy to do the next time too. And all of this is meaningless if you don't know how the cylinders are numbered on the actual engine. The one closest to the pilot is number one, and the one forward of that is number 2. Closest to the passenger is number 3, and forward of that is number 4. See enclosed image, where "front of car" is actually "rear of airplane".

Re: KRnet> Multi subject. VW2180 magneto, electronic ignition and more
Jeff: Addressing your concern, I will only speak to the SDS system. I have a dual SDS system with a main and backup battery. My system has redundancy in that it has two fully independent sparkplugs, computers, and power packs. I have two ignition three-way toggle switches (up-main battery - center off - down the backup battery). Below, I will describe how I use my system. I taxi with the backup battery to ensure that this circuit is operational. During my run-up, I switch to my main battery (both ignitions) and do the run-up by switching each circuit off and running the engine with a single ignition. In my experience, I see a very minute RPM drop between one ignition and the other. If you are afraid of an ignition failure on takeoff, run one circuit on the main battery and the other on the backup battery, and then select the main battery once you are at a safe altitude. Switching from main to backup is so quick that there is no noticeable engine performance drop because the change is almost instantaneous. The backup battery. BTW the backup battery is sized for two hours of continuous operation. The other feature that you will love is the customization of the power curve and the ease of Lean of Peak configuration. The ignition computer has a built-in manifold pressure sensor that is used to maximize your engine performance at altitude. The CPI computer has 64 settings that allow the programming of ignition retard or advance with reference to load on the engine. Load information is attained from the MAP (MP) sensor.

Re: KRnet> VERY cool 6 pack PLUS autopilot!
My KR2S is equipped with a Dynon D180 with the AP74 autopilot module though it is not needed with the D180. It drives a full autopilot and the two servos cost $800 each brand new (a slight price increase, I paid $750). They are small and very light with over 36 lbs of torque. They come in three different sizes. If you accidentally order the wrong servo, Dynon will trade you an upgraded servo at no extra cost to you. These servos are very intelligent and communicate through a network. Some of their software features are the ability for the autopilot to do a 180 deg turn with the push of a button if you inadvertently enter an IFR situation and you need to get out.

I did the "cart checkout" thing and with tax (and no waterproof servos) my cost came to $4200 with tax. I don't fly enough cross country to justify that cost.

In a nutshell I logged 38.3 Hobbs hours for the round trip. Sam logged the actual flight times and except for the first and last legs our times were the same. N133RM burns fuel at a higher rate partially to cool the engine and I pumped about 182 gallons. So that comes out to 4.75GPH but we had some extended ground runs. Overall it was a great trip. We had some equipment challenges and we worked through everything. On the way to MVN we had some high temps and high crosswinds. Like Faith SD at 97F and 12-15 knots 90 degrees to the runway. Kind of exciting. On the way home we faced some stiff headwinds like 44mph directly on the nose going past STL. Crossing the mountains had us in smoke and high moisture content. Pulling the carb heat dropped 300 rpm so you cannot tell me that a slide carb/ injector won’t make ice. We parted ways in Lewiston, ID Wednesday afternoon. That was kind of brutal as Sam & I had an adventure flying to the Gathering and back home again.. But we’re glad to be home. Between the 2 of we have some photos to share at a later time.

Luis, I'm that guy that mentioned the old newsletters, but not that we need to try to resurrect itit died shortly after the KR internet newsgroup was born (because the internet is so far superior to a printed quarterly newsletter), which then evolved into the KRnet email list. What I was referring to was the ads in the newsletter put there by people who were building proven components for the KR that were up for sale to other builders, such as bellcranks, fittings, brakes, etc. We need folks to produce parts for the FreeBird in a similar manner, built by people who can keep a few sets around for immediate delivery, without the current mystery and drama. I wasn't talking about a new venue for announcing first flights, sharing new ideas, and all that stuffdon't we have that in the KRnet email list, and the KRnet.org website? As for someplace to disseminate new ideas like FreeBird, I have already secured the www.freebird.org website for exactly that purpose. No, I don't have it up and running yet, because I don't have anything of substance to post there yet, but we'll get there. As for "Who will take the time to do this work?"thanks for volunteering, but it's being worked! As for new blood in the KR community, that's a major tenet of the FreeBird project. I can't think of a better incentive to build a certain airplane than to have FREE plans located on a website for free download (no registration, no privacy data taken). One look at how simple it is and a LOT of people will find it intriguing. Then go take a look at www.krnet.org and look at all the very similar planes already flying, and guys building their own engine, and making it all work!

Re: KRnet> O-ring Selection
Larry these are brand new Tracy O'brain brakes, which means that they are properly sized. The cylinders I purchased used, that is why I am suspecting fluid by-pass across the pistons. To address the proper scenario from your list, I have not been able to pressurize the brakes, so I am afraid to move it on an active ramp like my home base (KHQZ), it's got some pretty expensive airplanes just sitting on the ramp. Since replacing those components are pennies on the dollar, I believe that my best action is to replace the internal components of the cylinders and see if that fixes the issue. Regarding the fluid lines to the brake calipers, I have not found any leaks that would signal a defective brake line. By the way, thank you, I always look forward to your input.

The solution will require different action. 1. Do they hold at initial application of full power then fade? - problem 2. Did they ever hold at full power and now fail? - problem 3. If they have never been able to hold at full power from the first attempt - situation 4. Are the brake system components new from the manufacture and using the recommended fluid type yet fail full power run up? - situation Flying an airplane with brakes that will not restrict motion at full power is not necessary a safety factor. If you ever need full braking action your engine will most likely be at idle or at least a very low power setting. My Tripacer had drum brakes with both sides actuated by a single heal brake master cylinder with a rubber diaphragm mounted on the firewall with a cable attached to a lever under the instrument panel. I refereed to them as my "slow down only brakes ". I flew my KR for several hundred hours with Cleveland 600X6 wheels with low profile tires. When I converted to Cleveland 500X5 wheels there was a noticeable difference in the braking action available. Try some fast taxi test and use full braking action to see if the brakes are adequate. Use caution as too much holding power could put you over on the nose. If you have a swivel tail wheel of any kind, can you lock up one wheel while taxiing on the ramp and do a 360 degree turn on one wheel? If you have a "problem" there will be a solution. If you have a "situation" you most likely have inadequate brakes for the amount of full power engine thrust. If you determine that's not a safety issue get out and fly. The only fix for a "situation" would be an entirely different and adequate bake system. Thirty three years of troubleshooting taught me to first identify exactly what appears to be wrong and what I'm trying to fix. Good luck...

KRnet> SDS CPI Electronic Ignitions for Experimental engines
Sam Spanovich asked that I do a write-up on how I got my electronic ignition to work. The SDS CPI electronic ignitions that he and I are using in our KR2S VW engines are really a great piece of technology well worth looking into. Here is how I got my system to work... Though our systems are identical, Sam and I took different approaches as to "How to" install them. The difference between Sam's installation and mine was the location of the magnets and sensors. Sam placed his magnets and sensors in the rear of his engine, while mine are mounted in the front. Sam's installation made sense because he purchased his electronic ignition while his engine was still disassembled on his bench. This gave him the freedom to machine the necessary parts and place them in the back of his case. Conversely, my engine was already installed on my airplane with a dual magneto still attached... so this is where Sam and I parted ways as far as the "how to" do the installation. I must say that at this time, there were only two other installations of this type on a VW aircraft engine using the SDS CPI system. Sam's installation and a gentleman that had installed his on a Q2 with a Revmaster engine. Sam's setup would not work for me because of the reasons mentioned above, so I studied the Q2's installation. I liked the idea of using the propeller bolts to hold the magnets and his bracket design to hold the sensors; however, I did not want welds on my brackets. I made several cardboard mockups of brackets to study the best-supporting structure that would also be free of vibrations. This structure should also provide the necessary geometry to place my sensor within .068" from the magnets. These magnets were drilled onto the end of the propeller bolts in a pattern that offered the best timing solution for operating the engine...Several interactions later I was able to build a bracket that was vibration free and offered the best geometric solution for the flying magnets and sensors. The biggest problem left to solve was magnet sequencing (timing). I had to find a timing resolution between the magnets, the sensor, and the firing sequence of the engine (computer). The book had some great examples but those examples were for clockwise turning Lycoming, Continental, and Jabiru engines. My Revmaster turned counter-clockwise. I once again reached out to the Q2 guy but he said he didn't remember what he had used. The factory gave me some general solutions but I could not get them to work mainly because the propeller bolts are spaced 60° from each other,.and no other angular placement would work. So I studied the relationship between the magnet positions and the sensors. I needed magnet trigger #1 to fly past the sensor at approximately 90° from TDC. I knew that the computer would add 10° of advance. therefore the firing solution was to fire cylinder #1 at a cumulative delay of 100° from the sensor. As I said before, I could only set my magnets at 60° increments, I program the magnetic position on the computer to 90°. This translated into 60° actual and 30° theoretical. I then selected the bolt that was closest to TDC and I placed magnet trigger #1 there. By doing this TDC and trigger #1 were timed to each other. Every time trigger #1 passed the sensor, it triggered a delay of 90° plus 10° advance and the engine fired precisely at 10°BTDC. I then attached a timing light to tweak the timing and I settled at a magnet position of 104° from the sensor. I was ok with that because all of my settings were estimated positions and the timing light brought everything into sync. Presently, the system is working like a charm. My bracket is vibration free and solid as a rock. I am working with a machinist to fabricate a more permanent frame but for now, it.s working Luis R Claudio, KR2S N8981S -- KRnet mailing list KRnet@list.krnet.org https://list.krnet.org/mailman/listinfo/krnet

I was tickled when I noticed that you were using the SDS CPI ignition as well! Would you mind discussing where you mounted the Hall effect sensor for the three ignition magnets? I ended up drilling three holes into the flywheel and mounted the magnets on the flywheel; to mount the Hall effect sensor, I had to cut a piece out of the flywheel cover and ended up mounting mine basically at the 12:00 o’clock position on the flywheel, bolted into the crankcase (I unfortunately do not have any pictures of this due to having a new phone and losing all my old ones). I’m just curious if you have any lessons learned, or any better ways of mounting the sensor. Now that you are running the CPI, and the magneto drive is free’d up, if you ever encounter alternator problems or desire more amps (more than the standard Revmaster alternator), you now have the option to mount an automotive style alternator; it takes a little bit of drilling/tapping to make it work, but it is a much cheaper (and solid) alternative than purchasing another stator/coil type like Revmaster’s.

Re: KRnet> (no subject)
Sam that is an awesome story as I am about to put my KR to the air... Thanks for sharing Luis R Claudio KR2S N8981S Dallas, Texas On Sunday, July 17, 2022 at 04:51:12 AM CDT, Samuel Spanovich via KRnet wrote: My first time flying my KR2S was back in 2018, about a week after I purchased the plane and towed it on a trailer to its home in Mississippi. This was fairly early on in my flying career (~200 hours or so) and I certainly was a little intimidated at the new bird. After all, the KR2 is known to be a sporty little thing, that is a little sensitive in pitch, and I figured it would be a massive leap from flying a 172 (what I got my PPL in). I took about a week to get the wings on, start it up, and taxi it around on the ground. I even did some high-speed taxi testing on the runway to try to get a feel of how the differential brakes handled (again something I’ve never used before). One day, while getting ready to perform another high speed taxi test, I figured I’d run up the engine a little bit more than usual to see how much it would put me in the back of the seat. I ran the little Revmaster up (which was bone stock at the time), and started seeing 20 mph. Then 30 mph. Then 40. Before I could blink, 50 mph. Better start slowing down, I told myself. Nah, keep going. 60 mph Better do it now. Keep going!!! The heck with taxi’d testingI’m going flying. 80 mph - rotate. At that point, I pulled the stick back and had my first flight in a KR, and it didn’t take me long to realize what a great bird it was and how well it flew. The engine ran nice and smooth, the weather was gorgeous, and despite what I had read, it didn’t seem to be too overly sensitive in pitch. I did notice that the plane performed a little differently than a Cessna 172. Roll rate was quicker, climb rate was slightly higher, but most importantly, the ride quality was much, MUCH more of a roller coaster ride. While the 172 I had been trained on would handle most bumps with relative ease, my first flight in the KR2 felt like I was on a buckin’ bronco. The 80-90F temperatures in the south didn’t help. Still though, I wasn’t scared or even remotely discouraged; honestly I just embraced it. I had my own airplane, flying high in the sky, with just me, with almost no clouds in the sky, enjoying the beautiful scenery that Mississippi has to offer. I cruised around for about an hour, enjoying the sights, listening to the little engine purr like a kitten, and taking in that I was now officially a true aircraft owner. However it eventually hit me that I would have to get this thing on the ground, and that I had a total of zero landings in this airplane; I dialed up the tower for Key Field and requested to perform touch and goes for Runway 1 (which is a 10,000 foot long runway, much shorter than their 4K foot runway primarily used for GA traffic). The reply I got back from them was nothing short of hilarious; “Experimental 6399URogerreportum report a left downwind for Runway 1”. I’m pretty sure the thought such a small aircraft requiring that long of a runway absolutely blew their minds, but I wasn’t sure just how far down the plane would float, and I wanted to have every inch of runway available in case things got squirrely, especially for my first time. I recalled what the seller had told me when I bought the plane: “it’s speeds are very similar to a 172, you climbout about 80-90 mph and come in over the numbers around 80 mph”. I figured I would add 10 mph for my first time, and saw 90 mph over the numbers before I pulled power back. WOW did I float down the runway. I definitely was glad I had that 10,000’ runway because I’m pretty certain I didn’t touch down until about the 5-6k board. I immediately retracted the speed brakes and off again I went. I did about 4x more landings, each time floating significantly less and less, before making a full stop, then proceeding to go into the FBO to have some ice cream and hot dogs. At this point I called my wife, and explained to her that I had taken the plane flying (when I left the house I had no intention of flying, just more ground testing), so when I told her that I had landed in Key Field (just 15 minutes from our house), she immediately got in the car to come see me and come check out the little bird in action. While she didn’t end up going flying with me that particular day, I did get to show off a little bit on my next takeoff going back to my home field; taking off again on the 10,000 foot runway, and staying in ground effect about 10-20 feet off the ground, until reaching the end of the runway, then pulling back the stick to begin climbing out. I’m fairly certain I saw 120-130 mph on the airspeed by the time I reached the end of the runway. When I finally returned to my home field, the landing was uneventful and by far the smoothest one I had out of the 5 that day.

Re: KRnet> Things that fail
I think these discussions are healthy and welcoming. I read them and go "hmmm" then I make my own decisions. I have been flying since 1966 when I took my first ride as a civil air patrol cadet in High School in a PA-22 108HP. As a student at Embry-Riddle, I was an understudy of Dr. Richie (RIP) a true pioneer in failure analysis (FMEA) of everything aviation-related. I understand failure modes, and most importantly how to mitigate the risk for each independent system or collectively (through risk priority number= severity x occurrence x detection...) I am also very familiar with E-Mags and other electronic ignitions which is why after careful consideration I chose a dual SDS ignition system. It wasn't by "gosh or by golly" that I arrived at my conclusion. Considering that my initial choice of ignition system was a Dual Bendix D3000 mag with a single failure mode (the main coupling), I asked what else is out there... and here is what I considered 1. A dual mag setup such as the aforementioned dual mag - Four points, four capacitors, one coupling = Total 5 points of failure minimum2. An independent mag with an electronic ignition driven by the timing gears - Minimum of four points of failure (points, capacitor, two couplings)3. An "E-Mag like" with an electronic ignition driven by the timing gears - Engine couplings = two points of failure (minimum) 4. Two independent electronic ignitions with no mechanical moving parts - dual independent battery backups - Component failure 5. Just screw it and go sailing... My most predictable component failure is the spark plugs. So moving forward I then wrote a proactive maintenance schedule in my POH and annotated it in my conditional inspection form to reduce the risk of component failure. Additionally, during my selection process, I prioritized the failure modes of each system, mechanical and electronic... from highest RPN to lowest RPN noting that it’s worth emphasizing that it’s nearly impossible to address every potential failure. Instead, I focused on addressing the potential failures that would most jeopardize the safe outcome of my flights and I chose from analysis and not from bells and whistles... just my rambling thoughts here trying to justify that $50K I spent on getting educated at Embry-Riddle back in the day... keep building Luis R Claudio, KR2S N8981S On Friday, July 8, 2022 at 06:23:13 AM CDT, victor taylor via KRnet wrote: To answer Chris yes I do have a flying KR2 with a single electronic ignition though I was actually talking to Dan Diehl yesterday about adding a magneto for a backup. I do contract work for Velocity Aircraft as a pilot. We love electronic ignitions and put them on every airplane. They are the way to go and in the past have gone 100% electronic ignition but over time have had enough failures that we went back to having one mag. I also test fly new airplanes for M-Square who builds the Zenith CH-750 SLSA. I actually have had two electronic ignition failures with brand new aircraft there in the last couple of years. M-Square is still committed to 100% electronic at this point. Just to be clear I’m not knocking electronic ignitions nor their reliability. If you have dual electronic ignitions though you likely are relying on the same electrical system to run both systems. Up until four months ago I had never had a magneto failure in my 40 years of flying but recently I lost a magneto while ferrying a Grumman AA1A. Fortunately the other one got me to the nearest airport where a safe landing was made. There is a reason why aircraft manufacturers such as Velocity have reversed their positions on going 100% electronic. And that reason is failures in the past and accidents such as the one in Kissimmee. When Teladyne Continental first built their full FADEC engine system it kept experiencing total ignition failures in flight. After over a year of flight testing with multiple in flight failures yet not a single one in the test cell they finally got to the bottom of it. The problems was found to be the frequency that the US government uses to communicate with submarines was interfering with the FADAC system. The fix was simple by shielding the system. One of the functions of this group is to make the KR’s safer. That’s done by discussions and experience. Mostly bad experiences and I’ve personally had those bad experiences as a professional test pilot. All of us in this group look at canopy latches a little closer today than we did a year ago. Controls have gotten balanced, fifth bearings have been added to engines, fuel tanks are being moved to the wings etc. You would think that over the years we’ve fixed every possible failure point. Have we? It’s our duty in this group to be devils advocate at times and to point out past failures of similar systems.

Re: KRnet> KR parts from Lawn & garden?!
My thoughts exactly Chris... If I go, I want to go in a blaze of Glory... having survived Vietnam... I am on borrowed time anyway... but to Dr. Hsu's question on reliability, here is what I know... Racetech/SDS has been selling EIs to the aviation market since 1997 The factory claims that One ECU (computer module) on a test bench ran for over 145,000 hours continuously with no problems. Unmatched reliability is proven in over 20 million hours and 850,000 flight hours using their units worldwide... I think I made a good choice for my KR's ignition.

I understand all the pros for the Electronic ignition system that Luis listed, however I would not feel confident if the two redundant Electronic ignition modules are identical component. Yes, two independent power supply with separate batteries do contribute on risk reduction, but that might be not good enough to offset the "CCF" (common cause or common mode failures) contribution to risk of losing the system during flight Do you have some test or reliability data on the SDS CP1 module from the vendor?

| A Celebration of KRs
I have to admit that the KR has never really had a prominent spot on my radar.
Certainly not for any negative reason. Mostly, I think, because the design was
in its heyday before I became interested in homebuilts. And like anything we
do, our earliest experience tends to be highly influential.

Re: KRnet> Instrument Panel for my KR2S
That is an awesome testimony of what these things do... being an old military helicopter pilot I still fly low and circle the water towers and read the names on the tower then climb and locate myself on the maps... dangerous in a plane but effective... just saying On Monday, March 21, 2022, 02:03:14 PM CDT, James McGauhey via KRnet wrote: I fly a Dynon Skyview in Zenith CH-650. I was going to build a KR when this opportunity came up and 3 others joined me to share costs and build. Built from 2015 to 2017, flew WA to OSH in 2017 and 2019. This was 2019 event. Highly unlikely, but great to have Dynon and Nrst shows closest airports and some details, then just push Direct and flight plan is loaded and Load frequencies into radio. All with just pushing buttons quickly, no dialing or looking things up. Less than 30 seconds and I have heading and frequencies set. https://www.facebook.com/jmcgauhey/posts/10219488566378380 I always have a backup hard copy sectional in the plane. I figure for $8.25 every 3 months it’s cheap insurance. I’ll practice once in a while and in WA I’m lucky to have mountains and high points. Quickest way I found to locate myself is to see a peak, say at 10:00, then look for another landmark about 90 degrees, like a bend in river or something. Draw lines back to my location and X marks the spot, or close enough. It’s fast, easy, and no reliance on electronics. But electronics are great when they work. The Dynon gives me real time weather and TFR’s on the moving map. Like returning in 2017 along Interstate 90 over Cascades when a red dot suddenly appeared in my flight path in front of me. Took me a second to realize it was a pop-up TFR forest fire area. If I only had briefing 2 hrs ago before take-off I would have missed that. Just had to deviate a couple miles and go around the TFR. A round airspeed gauge gives you airspeed. The Dynon gives me airspeed, under that true airspeed, under that gps over the ground speed, under that wind speed and direction, and under that crosswind component. Get all that from a round gauge!! Or even a tablet. Love the Dynon!

Re: KR> Regulator wiring?
John this is the wire that I am using in wiring my instrument panel and engine
accessories including my voltage regulator and alternator. The Revmaster's
alternator for the 2100D is rated at 20 amps. You can downsize the ground by
one wire size if you want to... I am including an ampacity table for this wire
which is fire rated and can handle up to 600 Volts.
