From: Andreas Meyer Date: Wed, 17 Feb 1999 09:39:44 -0500 X-Message-Number: 7 Hi KR builders/flyers, I am currently looking into purchasing a KR-2 and I am looking for pointers for what to look out for when buying a used one. I tried the FAQ on krnet.org but it seems to be down and has been down for a while. Is there any other place where I can get the info? The KR-2 I am planning on looking at in the next few days has a 80 hp Limbach engine and the Diehl landing gear and wing. Does anybody have any experience with the Limbach engine? It seems like it's pretty popular in Europe but I wonder what the support for that engine is like in the US. One more question. The plane is currently registered in Canada and I'd be bringing it to the US. Does anybody forsee any problems in registering such a plane in the US? How about import duties and such? I'll be contacting the EAA and AOPA to see if they can provide me with more info, but if anybody on line has any experience I'd like to hear it. Thanks for any info you may be able to provide, Andreas Meyer ---------------------------------------------------------------------- Subject: Flap Motor From: DClarke351@aol.com Date: Wed, 17 Feb 1999 09:55:32 EST X-Message-Number: 8 Has anyone ever used the RV flap motor in their KR's?

It is a composite of three materials. FOAM, Fiberglass, and AC/spruce. In fact the KR was THE FIRST composite airplane. The title should be "All GLASS KR2S" not "ALL Composite KR2S" KR's are ALREADY composites.

I printed it out once. It is a reprint from a Kitplanes article. I have done a lot of research on this, and there are several circuits out there for this. However, just run to K-mart, spend $18.00 and buy one of those personal strobe lights, and glass it into your plane. Now all you have to do is divide down the 12V power to 1.5->3.0V and you have a strobe. I've got one in my KR now but the job is not completed. I haven't come up with a power supply design yet, I don't want to waste a lot of power going down to 3V from 12V, so I have been picky. However, the strobe solution I mentioned may not generate near as much output as an "official" strobe from Wehlen[sp?]. Jeff Scotts KR2S had his strobes on at the Fly-in last year and it was really impressive to SEE him taxi around. Looks REALLY impressive to have the two strobes timed to alternate. This is ANOTHER timing circuit that could be home brewed, but in my case, I now have more $ than time, and even then not enough $ to buy the cool alternative. So I haven't done the timing circuit. It would be nice to do a test of various strobe circuits to see what the Candlepower output is compared to commercial ones. I suspect there is a reason the commercial ones come with hefty power supplies. If they could design them out, they would. Ohh and any work with Strobes requires a ** SAFETY WARNING ** The voltages present in the strobe ciruits you can build or scrounge can be HAZARDOUS to your health. REALLY! NOT KIDDING. There are some websites discussing the use of disposable camera circuits and all mention this. The current stored in the capacitor can discharge and create thousands of volts. (A strobe is actually a small lightning discharge). -- Ross CHOCTAWCWR@aol.com wrote: > > have any of you do it yourself gurus devised a way to build from scratch a > strobe lite kit and if so would you share the parts list and schematic, > etc.thanks, charles robison > > --- > You are currently subscribed to kr-net as: rossy@saber.slb.com > To unsubscribe send a blank email to leave-kr-net-17800J@telelists.com -- Ross Youngblood Pager: (800)SKY-PAGE PIN#895-9073 Staff Technical Specialist voicemail: (800)538-6838 x 1632 Schlumberger SABER Bus Line: (541)714-1754 Corvallis,Oregon mailto:rossy@saber.slb.com ---------------------------------------------------------------------- Subject: Re: How not to From: "JEAN" Date: Wed, 17 Feb 1999 11:47:45 -0600 X-Message-Number: 11 Another thing about the 2 part foam is that it will continue to grow for some time after you think it is done.

Sharing ideas is the key to progress. Ten years ago I bought KR-2 plans with intention of building mine as a single seater. I will admit though that the main attraction for me was VW power, as I used to do a lot of Bug work. About that time there was alot of bad press concerning busted cranks and lost props, so I backed off. Now I discover that Steve Bennett may very well have solved the problem with the "rear drive" kit. Then I signed up on KRnet and found your website. WOW!! I was never thrilled with the tortured plywood method of construction, so your answer to this may be my dream come true. I will be following your progress closely, and the new airfoils as well. It really is, as you said, a whole new aircraft. May I offer ( tounge in cheek ) 1) a Doctors solution to a problem is an R ( RX - 2) ?? X 2) or for the California crowd how about the Medfly ?? 3) I suppose " Dean-a-Soar " is out of the question !! Sorry, couldn't help myself. If you have received a ton of useable and/or humorous suggestion could you possibly post some of your favorites? I think we'd all enjoy that. Many thanks for being an experimenter !!

The lodge phone number is 1-800-325-1708. Ask for a room reserved under the KR Gathering. All reservations must be made by 7/24/99 at which time all accomodations will be offered back to the general public. No organized transportation is provided by the gathering itself. Rental cars are available from the commercial airports in the area. Plan on an hour drive from Nashville although you could fly into Louisville or St. Louis. As the time gets closer you will find people make arrangements on the KRnet to share rides to cut down the cost of the rental car. The Resort is on Lake Barkley and offers boating, swimming, golf, tennis, hiking, miniature golf in addition to having a general aviation runway on site. You shouldn't have to leave the park if you don't want to. E-mail be privately if you have any questions.

Don, The standard KR cowling has an opening about 3" x 5" on each side yielding a total of about 30 square inches of inlet. Troy Petteway has been nibbling away at that, and has cut it in half with plenty of cooling remaining. Of course, he's using an efficient plenum (nice carbon fiber work!) rather than a pressure cowl too. He's running a 2180cc VW. I plan to do the same, except I'll have one inlet on the bottom of the cowl, and my carb intake will be on top. Kent Paser (Speed with Economy) reduced his Mustang II's inlet area from 60 square inches to 30, and picked up speed as he went, while maintaining pleny of cooling capacity. He's running an 0-320. It seems cowling makers leave lots of inlet area to ensure adequate airflow for sloppy installations. That's were a little extra work can be turned into free speed. You probably have it already, but John Thorp did an article called "Cooling and Cowling of Light Aircraft Engines" in the November 63 (bad month, as I recall) issue of Sport Aviation, and part II in December. You'd probably like it, if you don't already have it. And you probably saw the September 96 SA article on "Engine Cooling Problems" too. It's the kind of stuff you'd like (manometers, etc.) and has lots of even meatier references at the end.

In a VW, that can be bad news and is generally discouraged. My recommendation would be to use a woooden prop on any direct drive auto engine as the wood props generally don't have harmonic problems and to the best of my knowledge have never been credited with cracking a crankshaft. On the other hand, if you are using a redrive, then the Warp Drive prop is a fine unit. FWIW, I have many years of flying behind wooden props and am currently using a wood prop on the C-85 in my KR. I wouldn't trade it for a Warp drive or metal prop.

At last years Perry KR Gathering. I demonstrated the H.U.D. and my Fuel Management Control Board. I am assembling these items for my own KR2 and will sell them to any interested KR builders. I think the H.U.D. is shown operating in this years' KR video, they took some shots of it anyway. The H.U.D., .named "KNOT-VUE", because it constantly displays AIR SPEED and can be configured to monitor engine functions using auto sensors which lights alarm icons on the display. It's a after market automotive GM Delco display similar to the one installed in the Grand Prix Pontiac, also made by Delco. It's taken me 2 years to R & D the unit on a part time basis, lots of microelectronics in it. It should be reliable becouse it beeen in Pontiacs for 7 years now. You can see what the H.U.D. looks like by visiting your Pontiac Dealer or see it on the www.jrl-engineering.com web page the cost is $575.00 The KNOT-VUE H.U.D. will not take the place of any aircraft instruments, but is used as a complement to those instruments (just as it is in the Pontiac). The KNOT-VUE H.U.D. has been bench tested against a calibrated Rock Mountain Instrument u/ENCODER ( See Photo on Web Page ). KNOT-VUE has been flight-tested and checked against GPS air speed and has been accurate within + - 1 knot. Repeatability is good. With a "in your face H.U.D.", like the KNOT-VUE, keeping your eyes focused outside the cockpit while maneuvering, with real time knowledge of air speed, can help your confidence level during flight tests. The H.U.D. weighs about 8 oz. complete with a Black Plastic Enclosure, fold-down Refractor Lens and Pressure Transducer Board that connects to your Pitot Tube Sensor. The H.U.D. is all solid state electronics requiring 12 volts, 3 amp. circuit. The display projects the digital speed and alarm icon images on a flip-up Refractor Lens, which is positioned in the line of sight (vue) of the pilot and in front of the windshield. The image looks like it's floating outside the windshield above the engine cowling (an optical illusion). Delco repair shops carry spare parts and can repair the displays. The Fuel Management Control Board is another part of my project. Its for keeping my header tank full of fuel by pumping fuel from my left and right wing tank. Technically the Fuel Management Control Board is a "On Delay Alternating Power Relay". It controls two 10 amp electric fuel pumps. A schematic of the field wiring is available on the www.jrl-engineering.com web page along with a Photo of the Fuel Management Control Board. The Fuel Management Control Board uses one Float Switch (Normally Closed Contact with tank full) and we program the adjustable "On Delay Timer" for 15 Minutes ( one Gallon fuel burn for a VW) after the float contact opens due to fuel burn. When the timer times out after 15 minutes the No. 1 Pump is turned "ON" and fills the header tank, the float switch shuts off the No. 1 pump. Then on the second cycle the No. 2 Pump turns "ON" and the alternating cycles continue. The header tank level is constantly shown by the header tank site gauge. The process is controlled by a programmable EEPROM. A "Auto-Manual" Control Switch is used with two "On-Off" Switches for full manual control of the process. Field Wiring Schematic is available on our web or by e-mail. Buy it from me or build it yourself. Information about the KNOT-VUE and Fuel Management Control Board will be entered on the JRL ENGINEERING CONSORTIUM LTD. Web Site at www.jrl-engineering.com. I can be contacted at jrlkc@mindspring.com and ron@jrl-engineering.com also. Thanks to the KR NET for doing such a good job and keeping us all inspired and going on our KR projects. Sincerely, Ron Eason P.S. To Vue or KNOT-VUE is the question.? ---------------------------------------------------------------------- Subject: Sport aviation From: "Stefan den Boer" Date: Thu, 18 Feb 1999 08:29:58 +0100 X-Message-Number: 23 Hai netters. Over here in the Netherland I tried to get a edition of the lot spoken edition of sport aviation. Every shop I asked was the answer negatif. Is there somebody in europe who is having an edition for me . Or is it possible that somebody it will send to me from the U.S.A. Please contact me.

It is a composite of three >materials. FOAM, Fiberglass, and AC/spruce. In fact the KR was >THE FIRST composite airplane. By that definition, isn't a Piper Cub a composite of steel, cotton cloth, and aircraft dope? I think that beats the KR.

Answer to question number two, sure why not but will it fly? >:o) I once asked the exact opposite of this question on rec.aviation about Light Miniature Aircraft, a kitplane maker that sells kits for 80% to 95% -sized replicas of Tayorcrafts, Pipers, and other classic tube & fabric designs. I asked what point there was in making 95% versions of certified planes, since you're eliminating the possibility of using salvaged parts and the performance gain would be trivial. The answer came back that weight & drag are proportional to the cube of length, so a 95% replica would require significantly less power for the same performance. Obviously, this would also be true for 110% replicas.
