The KR flys great , no trim needed. Climbs at 500 fpm and cruises at 135 mph at 2500 rpms, at 3000 rpm it cruises at 145 mph, with an 1835 and a gross weight of 980, for a heavy aiplane the 1835 Vw has amazing power with a 52-46 prop. To recover the airplane in stalls and bad landing attemps, no altitude loss, just slingshots when you apply full power. I do have to say one thing, I wish I paid more attention to the weight when building it, this was my first airplane attempt and I did not think I was building it heavy, but somewhere the weight is just in it? I would like to get rid of some of the weight, wher do I start? One place would be the wings, mine have fuel tank in the outer panels and I glassed them with two layers of glass and four on the leading edge and a lot of filler. Does anyone know what the Diehl wings weigh when finished with no wing tanks? I also can lose weight in the fuse here and there, my goal is about a 150 lbs. I know this is a lot to lose and hard to do, but I will do it over time and try to keep flying it.in the process. Guys all the talk on engines and weight, from flying mine, the 1835 VW has plenty of power to fly a heavy airplane, but your performance, rate of climb, and cruise is hampered and putting another person is going to be questionable if not impossible. Putting in a more powerful engine is one way of improving performance but that also is going to add weight that I don't need. GUY BUILD THAT AIRPLANE LIGHT YOU WILL BE GLAD YOU DID!

I know because I had one in my baja bug and when I put the new fuel cell in the back seat the tank was at the same height as the dual carbs. When the car was shut down fuel would still flow into the carbs and into the cylinders. As I tried to start the engine again the cylinders were full of fuel and would hydro lock the engine on startup. solved the problen by installing a fuel shutoff selenoid in the fuel line. Just like the Volkswagon people did on the solex carbs so the engine would not diesel on. Dave Mullins Nashua, NH KR2S or Bust!!

Warron ---------------------------------------------------------------------- Subject: facet Fuel Pumps From: "RONALD.FREIBERGER" Date: Sun, 15 Aug 1999 10:38:37 -0500 X-Message-Number: 8 My FACET pump has very high cracking pressue, and would not allow gravity feed. Tom Crawford advises that his does allow operations with gravity feed. Clearly, there is a variance in the pumps in this respect. In my opinion, the pump ought to be bypassed with a low cracking pressure check valve. The only one I know about is A/S #10630 , page 147 of the 97/98 catalog. $23.50 A KR2 doesn't have much feed pressure in a climb, and I wouldn't want to give much of it away.

The facet pumps will only look like a slight restriction in the fuel flow. If you are thinkin gof pump on during takeoff and off for cruise with fuel flowing through the pump, that is probably a very good setup although I would be interested to see what your fuel flow measurement is. Also, it is worth noting that fuel will also bleed backward through them. Mine are mounted to be used to transfer fuel from the wing tanks to the header tank. I need to add a check valve to the line because the top gallon of the header tank bleeds back down through the facet pumps into the wing tanks usually causing an overflow if I fuel all three tanks.

I bought a polyetheylene 6.6 gal fuel tank from JC Whitney Co. for $23.99. It is on page 142 of their catalog under Marine Fuel Tank. I use it as an auxillary longer range tank. It fits perfectly in the right front seat area between the front and rear spars. I mounted a solid state fuel pump onto the lower front of the main spar and hooked a line up to the header tank from the aux tank. It has a fuel guage in the cap along with an air vent and a standard screened fuel withdrawal fitting 1/4" x 18 npt (internal) In short it is neat. It also makes a nice arm rest.

Tragically, John Denver didn't pick the spot, although it was chosen with the best of intentions. Apparently, the standard design to put the fuel shut-off in front of the pilot required running fuel line through the cockpit, so the builder decided to have the shut-off behind the pilot as a safety measure. I don't know how much time-in-type Denver had, but he had almost no time in that particular plane, and he took off on a brief flight without bothering to refuel, which required him to change tanks.

I believe that the law says that ignorance of the law is no excuse. You should sopport that one to the best of your ability. If you do not then you are out of a job aren't you? If you feel that people believe that lawyers spend their time scheming to take advantage of people then mabey you should ask your self why they feel that way, there may be a reason for it.

Larry Shull ---------------------------------------------------------------------- Subject: Flying and having fun From: Jim Faughn Date: Sun, 15 Aug 1999 14:44:35 -0500 X-Message-Number: 15 I moved my KR from Sullivan, MO to Smart field in St. Charles, MO about a month ago only to find out the hanger I co-rented had moisture on the floor. This was after two weeks of no rain. Luckily I had run into a guy building an RV that had a hanger about 10 minutes from my house at a very nice controlled airport. So after a few phone calls I had part of that hanger rented and moved my KR from Smartt field to Parks airport in Cahokia, Illinois. As I was approaching the airport the tower told me that my transponder wasn't reporting mode C so after cycling the transponder and still no mode C I landed and called the handy avionics tech. We pulled the transponder and encoder only to find that the transponder had a dirty connection and the mode C had gone on vacation down south. Again luckly, I borrowed one of his loaner encoders and was up flying this morning. I can't tell you how much fun flying these airplane is. After years of an hour commute,each way, to the airport this 10 minute deal is going to be great. Bottom line is my plane and engine are doing fine with the new encoder due in Thursday. I believe I will now be able to finish and paint the wheel pants for the gathering and I am looking forward to giving rides again this year. I talked to Steve Bennett yesterday and we will be joining up to fly in to the gathering. Is anyone else coming from up north that would like to fly-in in group on Friday morning??? I'm looking forward to seeing everyone at the gathering and remember - flying is more fun than building so I just hope you'll all hurry up and finish your airplane. -- Jim Faughn N8931JF St. Louis, MO mailto:jfaughn@mvp.net (314) 652-7659 or Cell (314) 346-4038 ---------------------------------------------------------------------- Subject: Re: Another systems question From: JEHayward@aol.com Date: Sun, 15 Aug 1999 16:19:29 EDT X-Message-Number: 16 In a message dated 8/15/99 8:25:20 AM Mountain Daylight Time, mikemims@home.com writes: << Those of you who are familiar with the facet (spelling?) type fuel pumps.

The Challenger is of the ultralight family and I've almost finished mine. The idea was to have a backup for the Mikuni pulse pump on the Rotax. Of those using it some had it in series with the pulse and some in parallel. Most are using it in series but for take-off or landing only as a safety thing. The most simple way has been the series installation and fuel seems to flow just fine without it on. Also, we are using the 2-3 psi model instead of the 5-6 psi.

Don't be afraid of it, if you run at 3200 then it is a question of economy which will be over 3 gal/hr, but not bad. Not sure what you weigh, but if you can get it down to 550 lb.. then your in the ball park. You don't need the kitchen sink in it. This is the tendency we all have "overbuild". Why? My thoughts that anything over 550 lb. is no longer a KR but a takeoff of a KR, this should raise a few hackles, who gives a dam, but your out of specs for a KR. Like it or not! You would need a pretty hefty engine to run a 62 in. prop and you really don't need it. Enjoy, your on the right track in all aspects.

BUT- in high angles of attack, RE takeoff, the EGT rises a bit, signalling to me that in that situation, a pump is needed in my plane. In straight and level flight, cruise RPM, it runs fine without the pump- if I turn it on, I notice no difference in performance, or gauges.

If you want to stick with the 1835 it sounds like you're going to have to go with a prop with less pitch. Maybe you can borrow one (or more) from other KR pilots to figure out what you need. Now's the time to "network". Maybe somebody could bring you one at the Gathering. I'd think that just about every KR owner has at least one prop that "didn't work out"...

Any ideas would be greatly appreciated and anybody that >wants to visit come on down. >Mike Garbez N998MG >Griswold, IA >msgtlg@netins.net I would be willing to bet that you are running too much prop. There was a KR2 at Sun-n-Fun this year with a 2400cc type-4 engine running a 54-46 prop and was flying very well. Based on what I've seen and read over the last few years, I'll bet that a 52-42 would be about right for your engine. I would think that you would want at least 3200rpm static and 3600rpm at full throttle at altitude. At the RPM's your turning, you are well below the power curve of your engine. A little less pitch will allow it to unload and produce more power. Interesting that you are getting an extra 50 rpm's with the secondary ignition. I wonder if your mag is timed correctly. With the small size of the VW combustion chamber and the fairly well located plug, I wouldn't expect to see much difference between single and dual ignition. Another possible problem is your propeller's actual pitch. According to a chart I have, the speed and rpm that you reported previously indicate that your pitch is somewhere around 50", rather then the 46" that you reported. At least these things might be simple and easy to check and verify. Good luck and congratulations on your first flights.

Seems that 3000 static and 3300 to 3400 in flight at full throttle is what seems to feel best. Guys keep in mind that a props pitch really means nothing because they vary from builder to builder. I am willing to bet this prop that is labeled 46 inches is actually much more. We have a 2300 CC Vw that is running a Props Inc prop that is labeled 52 x 48 and its perfect. On the other hand we have a 2180 that runs a 52 x 51 and its perfect also (3000 static, 3350 full throttle in flight). Another thing to check is the tach. These darn things seem to be 200 to 300 rpm off quite frequently. Try to find one of those model airplane tachs and take it with you on your next flight. You can just hold it up to the wind-screen and it will give you a very accurate digital reading. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Filling and Sanding again! http://www.fortunecity.com/marina/anchor/270/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: RE: Prop pitch From: "garbez" Date: Sun, 15 Aug 1999 21:59:40 -0500 X-Message-Number: 33 Wayne Wrote: Another possible problem is your propeller's actual pitch.

I know I built 5 props until I got 3600 level and full throttle then I was satisfied. And, yours does not seem to be a prop problem to me, unless it's mislabeled, you should have about 23-25 degrees at 2/3 the distance from the hub. The prop I settled on would only give me 3400 but I trimmed it a bit and got it up to 3600 where I wanted it, just a little reserve. Personal preference. Your fuel flow seems okay to me. If you got the camshaft from Steve, I would think you got the right one. If I remember correctly without digging into my big data bag, I think the Scat is a #20 and a HAPI is a #60, I have the lifts and duration, but not at hand, personally I think this is where I would look at because it seems consistent. If by any chance that it is a stock cam, then that is the problem without a doubt. Good Luck!!
