Good article. In gliders we practice a rope break at 200'. The instructor pulls the release and you immediately roll into a 45 degree turn to do a 180 and land downwind. An important lesson you learn is that before you take off you determine what altitude you will do a 180 and you verbally call it out as you climb through it. You also determine before you take off which direction you will turn which is into the direction the cross wind is coming from if there is one to keep you closer to the runway after you complete the turn. It is a very good idea to practice departure engine failures in your powered plane at a safe altitude to determine how much altitude you loose in a 180 degree turn. ------------------------------ Message: 5 Date: Mon, 18 Jul 2005 18:46:41 +1000 From: "Barry Kruyssen" Subject: KR> New KR2s flying To: "KRnet" Message-ID: <001201c58b75$387ae5e0$6906070a@technologyonecorp.com> Content-Type: text/plain; charset="iso-8859-1" Hi All, Good news, Ken Warland of Australia did his first flight on 3rd July 2005.

I received a half set of WAFs from the US ("RR genuine parts"), which I am not going to use, because the holes are not exactly located as mine. I also ordered some 4130 steel of the correct width from the States, enough to do a complete set of WAFs, which I should receive anytime now. In the meantime, I have cleaned all my WAFs, and drilled the lightening holes as per plans (they were all 1/2"). I might simply finish these (paint with Zinc chromate primer), because the local authorities are getting nervous with my building frenzy! But there is still a pair of WAFs I want to redo, because the attachment hole is oversized, and I don't like that.

I am over simplifying but basically the less drag the plane makes for a given horsepower the faster it flies. And drag reduction has MORE effect than more hp. Several companies have done test after test and proven that it requires much more increases in hp to overcome a dirty airplane, than it does to get big improvements by reducing drag and get the same speed increases, using already available hp in the plane's setup. Why is this? Because it is very easy to increase cruising speeds and top speeds when going from say 80 knots to 120 knots in the same plane by just adding hp and maybe a prop change. This is because the parasitic drag, or drag produced by anything in the slipstream is much less at lower speeds, and the hp increase is taking the plane from having marginal thrust above minimum to climb and cruise, and adding more than enough to cruise with hp to spare. Also, altitude has an effect based on the density altitude, and the friend may be reporting true airspeed, not indicated based on adjusted numbers. Now take that same plane and try to push it up to say 200 knots. Horse thinking would have you say, well if I double the hp I will fly twice as fast, right? NOT! Parasitic drag begins growing rapidly above certain speeds in different planes, and in fact if the airspeed is doubled the parasitic drag is 4 TIMES what it was at half speed ( FAA Pilots Handbook Aeronautical Knowledge ). This is why double the hp increases the climb rate so much, because climbing is a function of excess hp over what level flight requires, and does NOT necessarily translate to alot higher cruise speeds. Take 2 KRs: look closely at the attention to detail. The one that has the cleanest airframe, the slipperiest paint, the lightest weight, smallest wetted area, least drag producing anything, and he will be the fastest for a given hp of others. Troy Pettyway has one of the fastest KR2's, and also has one of the cleanest KRs. Brain Kraut referenced a book written on this very subject called speed with economy, and is well worth reading to provide even more information. Look at a Varieze, 100hp and 200 mph cruise.

Brian Kraut +++++++++++++++++++++++++++++++++++++++++++++++++++++++ In theory I've had to pick up a bit but whatever it was is not noticable on a VSI that is bouncing around anyway. Whatever horsepower was needed before to overcome the drag of the wheels is now available for additional climb. That drag, however, was a lot less at climb speed than cruise speed so the effect would be much smaller.

He won the Sun-N-Fun race one year and averaged 193 mph ,as I recall. There is another KR2 just south of Nashville, Tennessee that is that fast or more. His is very light also. The more your KR weighs, the more lift you must produce and lift equals drag. Keep it light and "slick" with good streamlining. Also remember, these two KR's may be running 0-200's but they are pulling more than 100 hp from them. They are running them to 3000 rpm ,or close, and probably getting 120+ hp. They have pushed their KR's into the part of the performance envelop reserved for those that know what they're doing and have the piloting skills to handle it. RR claims a cruise of 180 mph on a VW but let's be realistic. That was up high, with a turbo VW, in probably one of the lightest KR's to ever fly. I'm thinking 170 mph with my KR ,that weighs 765 empty, is running an 0-200 with 2000 hours on it and fighting to pull 100 hp at full throttle cruise, is probably as good as I'm going to get. That doesn't keep me from LOVIN' IT though. KR's are not "cookie cutter" airplanes. Every one will be different depending on weight, engine used, engine/prop combination, gear mods or lack thereof, canopies, and the list goes on and on. None of them are bad, some are just better (faster) than others. Larry Flesner ------------------------------ Message: 13 Date: Mon, 18 Jul 2005 10:36:08 -0400 From: "Kenneth B.

Reduce the parasitic drag. Reduce the incuded drag. Increase the HP. The parasitic drag can be reduced by paying attention to detail with clean lines, and fairings to clean up the airflow. Induced drag is a function of the weight your wing area has to lift. Lift induces drag. The lighter you build, the less your wing has to lift, and the less induced drag you will have to overcome. HP is pretty simple, but mounting a bigger engine with more weight isn't always the answer. HP probably has the least effect out of the three items listed here. HP will affect take off performance and rate of climb much more than overall speed. When I changed from a tired C-85 to a high compression O-200, that was good for only 7 knots. As for gap seals, wheel pants, etc., Larry and I both picked up 15 mph with the RV series wheel pants over our 5:00x5 tires. In my book, that's pretty darned significant. A quick check of the charts with HP and a variable for prop inefficiencies will show that many KRs have less than 2 sq ft of flat plate area of parasitic drag. With that tiny bit of parasitic drag, any improvement you can do to the airflow makes a significant impact to the performance of the plane. I tested gap seals on my Diehl skinned RAF 48 wing and found no advantage at all, although the guys with the new wing report that gap seals make a significant difference for them. As some of the guys on line may have noted, my KR is undergoing an aerodynamics overhaul this summer and should come out sometime this fall as a cleaner faster flying machine.

Tig is certainly easier to do a top quality job, but MIG is also acceptable provided that the penetration is good and the welds are good quality. You may also need to normalize the 4130 after MIG welding. Acetylene welding is also acceptable practice, provided that the weldments are of good quality. I usually tack with a MIG, then weld with acetylene simply because that's what I do best and I don't have ready access to a TIG. That includes having scratch built the engine mount for my Avid Flyer when I adapted a VW to it. Reference AC 43.13B for more info on acceptable practices. The Stinson 108 line was all welded at the factory with stick welders and they are known for being pretty stout airframes.

To: Message-ID: <00eb01c58bbd$46a6bf20$0401a8c0@HAROLD> Content-Type: text/plain; charset="iso-8859-1" Hi Netters. For those that measure their epoxy by volume, I suggest instead of pumps use syringes. Go to the local drug store and buy a 50 ml syringe. They are cheep. Even though you may be using 1 volume to 1 volume of epoxy to hardener get different sized syringes. The reason is that sooner or later you will stick the epoxy syringe into the hardener by mistake. If the epoxy is a thick type, cut off the needle fitting and run a 3/16" drill into the end of the syringe. This will make it easy to draw up the thick epoxy. Next use a fine tipped black permanent marker to go over the volume markings on the side scale of the syringe. Otherwise the epoxy will gradually dissolve off the marking. Add a stripe of colored tape down one side and on the end of the piston. Cover the entire cylinder with clear cello tape. This will preserve the volume marking indefinitely. Stand the syringe in a can or jar after each use. Do the same with the hardener sysringe but use a different colored tape on it. I use plastic jars for the epoxy and hardener. Peanut butter jars (plastic) work well. Color code them too. It does not take long to estimate the volume of epoxy that you require for a particular job. Don't mix more than you require. Get a couple of small syringes too for small jobs. Get a pair of 5 ml, 10 ml and 20 ml syringes. This way you will always have the exact mixing ratios in your glue. With a syringe you can see that you have the required volume. You are not relying on a pump which might have sucked a bit of air around the piston or might not have been pushed all the way to the top or bottom of it's travel. And don't forget the gloves. Keep that epoxy off your skin. I think that the blue "Tyvec" gloves are the best. They are tougher than latex or vinyl gloves. Clean the gloves off with "varsol", hang them up to dry. Next time use "Baby Powder" on your hands before putting them on again. They will last a long time this way. Sorry if I got a bit wordy.

I wrote a couple of weeks ago about KR2 stuff I had for sale from a bad project. Most of it is gone now. In fact, all that is left is two sets of the original retract gear and one unused premolded turtledeck. Thanks to all who showed interest. -Don ------------------------------ Message: 22 Date: Mon, 18 Jul 2005 20:28:58 -0500 From: "Joe" Subject: Re: KR> Group Fly to Oshkosh To: "KRnet" Message-ID: <001f01c58c01$3cfe6c90$67cab4d8@Denise> Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original The problem with camping with your KR is you will be away from the main part of the flightline and fewer people will see the KRs.
