The readings with the pipes unsilenced were about 85 dbA at about 5 feet, pretty much uniform from front 10 o'clock to rear 7 o'clock. At about 25 feet, they drop about 10 db. This is on the ground. With chrome VW tailpipe silencers hose-clamped in place, readings dropped uniformly about 10 db at both idle and at about 2000 RPM. Remarkable thing is that with the silencers in place, almost all you hear is prop. Extremely silent. You do, however, get a 'meaner' sound without the silencers, but still very acceptable. Obviously, since Paul is only doing taxi tests, we didn't get to do any fly-over sound readings. If sound is a concern in your area, don't mess with fabricating a "Swiss" silencer or anything- just get some VW silencers and you're there.

Because of low ceilings and generally socked in weather, only one was able to make it on Saturday, Frank from Smithville, TN in a stock KR2 that was built in '88. He even took the oppportunity to talk Troy out of his prop, since he was only getting 3100 rpm out of his 52 x 48 prop. Troy's was actually a 52 x 52 Sterba, but the consensus was that it worked better than the old one. Those who drove in and followed Dana's directions got to tour the Saturn plant parking lot on the way to the airport. Mark Lougheed's plane was delayed several hours so Dr. Dean got to know the Nashville airport pretty well while waiting. Troy flew several missions in his L-19 to keep us entertained. Lack of KR's also led us to Troy's house Friday night to see Troy's plane under reconstruction. We carried away lots of good ideas, as usual. Tom Crawford had been stuck in Anniston, ALA until this morning (since Friday afternoon), but we heard he was off and flying this morning. We don't know if he managed to stop at Columbia but indications are that he made a break for Oshkosh while the gettin' was good. After two trapped days in Anniston, I can certainly sympathize. Despite the lack of KRs, I don't think there was a soul there that didn't think the time was well spent. I doubt that any of the 35-40 builders left there without something that would eventually save them many hours of construction and frustration. And there was the bombshell that Dr. Dean Collette dropped when he showed us his fuselage pictures...it has a rounded bottom! He'll scan them soon, but suffice it to say, there is a wonderful new way to do KR fuselages that is faster (the gussets are all 90 degrees!) and more pleasant looking, and way stronger due to the one piece "U" shaped construction. More on that later. You guys haven't started your fuselages yet, have you?????? Sunday morning Steve Eberhart and his wife, Dr. Dean, Mark Lougheed, and Rich Parker managed to find their way to Huntsville to check out my project. Despite the rough edges, they seemed to have picked up a few morsels of information that can only be gained from staring at a half-cooked project. See ya'll in Perry...

Any areas where you have gas or oil residue simply needs to be sanded. Use 320 grit and just sand a couple a layers off and re-apply the Smooth Prime. It will obvious if you didn't get all the residue off. If you didn't get it all just sand some more so the the Smooth Prime adheres. I'll work, I left some oil drops on it over night and sanded the following day, rolled some more on..............no problem.

Don't do any high speed taxi testing unless the airplane is in a configuration to fly (i.e. the airplane is completely finished and and preflighted, ready to fly) and make sure you have the same amount of fuel in the airplane you will have for your first flight (about two times the necessary fuel for the intended duration of the flight.) 2. Flight testing/taxi testing is a SOLO event. Unless you weigh 330 lbs, you had one too many people in the airplane. I won't speculate as to why you wanted to taxi it with two people, but I will make the general comment that it isn't a really good idea, especially when there is a good chance you may get airborne.

Not enough Here in Indiana, we had a very unfortunate accident/fatality with a neat new homebuilt. It was a taxi test prior to first flights that launched inadvertently ( I've been there too!) It came at the culmination of a complex project that included building a unique gearbox, unique propeller hub, on an GM Aluminum Engine.. the point is, these guys were really smart and competent. But, they ran out of fuel early into the flight, and had a fatal accident before they learned to fly it. The moral to this story is; Don't take an airplane onto the runway without enough fuel for a decent familiarization flight and successful approach to landing. The second line is, don't spend a lot of time doing high speed taxiing. When it's ready, use a lot of power, keep your speed up 'til you learn to fly it, and go high enough to feel it out safely. Another suggestion is that when all you friends come out to see the #1 flight, find an excuse not to do it. Later, when you're calm and it's ready, go for it with a friend in a chase plane to keep you company.

Been there 3 times, and this works; >don't be pressured, you'll have plenty anyway I would suggest a SMALL ground crew. They should know how to shut off the power and open the canopy just in case. A handheld radio to provide ground support seems like a good idea. The crew should be small and aware that the pilot can cancel the flight for ANY reason at ANY time. As far as fuel...lots just in case. If you need to divert to another airport or have to make several approaches...seems silly to run out of fuel.

HI gang, After another couple of days on filling/sanding the bottom of my KR I'll be ready for a tail wheel. This msg runs on a little long but I'd like some opinions. I just finished modifying the wheel pants (A.S.S. eagle series #112) by scabbing on fiberglass fairings and covers for the brakes and gear legs. I'd like to work through the tailwheel issue before I put her back right side up. I've narrowed it down to: a) buying the A.S.S. homebuilder 4" swivel/steerable tailwheel assy (pn L-691) and the 1.5" single leaf spring (pn 06-14500). b) same as A but making a fiberglass spring. c) Making the whole set up from scratch. the bad points: a) I don't know how well the height of the whole assy will work out but it seems it may be too tall. If I assume a wing incidence of 15 deg on the ground which is near full stall landing, and a 20" assy length, then the tail wheel/ground interface should be about 7 inches from the bottom of MY plane. If I don't like it I'll be forced to make my own any way. This set up also seems the draggy-ist and pretty heavy. b) Making a spring lets me design for the KR and not just take what's out there but making it fit a tailwheel assy designed for attaching to a smaller steel spring might be tough. This set up is still heavy and draggy. c)This is a lot of work and I give up the full swivel feature (which I'm not really sure if I want or not?) good points: a) very fast to put on and press on with the rest of the plane. b) I dont have to build a tailwheel assy, I can tailor the spring height and stiffness to my particular KR geometry. c) cheapest, and probably the lightest and cleanest (and weight back here is the bad kind)! If any of you have the a) combo of tailwheel and spring (Mike isn't this what you've got?) I'd appreciate some geometry info. total length from fwd spring hole to tailwheel contact point.,total height, and also spring thickness so I can check the strength! Any comments on the desirability of the full swival feature? wouldn't the tailwheel steering springs still stretch enough to pivot 90+ deg? I'll need to decide soon but I keep changing my mind between them. Any advice out there to tip the scales? ------------------------------ Date: Sun, 26 Jul 1998 18:55:23 -0700 From: Micheal Mims Subject: KR: Progress update Well I didn't high speed taxi today, dual or solo but I did manage to get the engine ready to have the case split. So far so good, everything looks very low time. Looks like all I need to do is have the jugs cleaned up (bead blast combustion chamber and intake, exhaust ports) and lap the valves back in and I am in business. I will need to pick up two intake tubes for the two rear cylinders but I have heard those are pretty cheep. I just finished cleaning up one of the pistons and associated hardware for one jug and I have one thing to say, "man are those big pistons!"

I am sure its a little heavier than the plans built tailwheel but so is my entire airplane. :o) The spring is 1/4 inch thick, and with the small tailwheel, I would guess the bottom of the fuselage is about 8 to 10 inches off the ground. Jeff Scott has the same setup and loves it. I have only flown taildraggers (C-185, PA-18, etc.) that have the full swivel feature so I don't know any different. Once you get used to how much pressure it takes to break it lose you can turn your plane on a dime! Kinda nice. Yes I am willing to bet its a little more draggy than the plans built unit but I don't think the plans built unit would have stood up to my fat cow of an airplane. Plus I will add a nice fairing once the test flying is over. Another KR flyer at our airport it changing from the plans built style to the same setup I have.

Got to love those VWs! >> I did manage to jig the fuselage and make all but rear end gussets. I was just too exhausted and did not want to make the last gusset from my fingers. Hopefully I can go to Chino during the week and glue every thing together. I am using a 8" compound miter saw ($100 (sale) from Home Depot) and a small disc and belt sander ($75 from Home Depot). I have never worked with these tools before and was able to cut most of the members and gussets net shape. I drew the fuse on the table top, measured the angles of cut, length and voila. With a small enough protractor one can probably measure from plans, although my fuse is four inch longer than the S model. I made two of each so second side should go much faster. I strongly recommend the two tools. The are cheap but can be calibrated to give 'outstanding' results. I made some test cuts and using a electroinc calipers adjusted everything to be within 5 mils and perfectly square. On the Dragonfly VW front. Allen was able to start it the first time he cranked it. Pretty good considering he changed all four cylinders and overhauled heads. later he took it out to taxi (cowling was still in the hangar so I know he did not fly it). Valve covers had minor leaks (which he was fixing when I left) . the engine sounded pretty good. So we have one neigbor who is happy and one who is not with VW. Both fly Dragonflys.

Do we glue the gussets with the vertical members >or glue them later? > >Thank > >Haris Ashraf I do them all at the same time, though I have heard of others adding the gussets later. When doing things like the diagonals, it sometimes helps to have the pressure of the gussets to keep the diagonal in the proper shape. You need to try the Gusset Clampett technique, I think there is a GIF of it on Mike's WWW site. Basically, you take a little angled chunk of 5/8 wood (cheap wood, not spruce, smaller in front than back to get in there close.:) and use a roofing nail with a small spring behind the flat head, and insert that into the wood chunk. You then apply the flat nail head/Clampett to your gusset, using moderate compression pressure, but not _too_ light, and mark where the block ends up. Then you remove the gusset, glue the Clampett down with 5 minute epoxy, and when you have applied your T88 or other glue, the nail is pulled back to place the gusset. It will squeeze out the excess glue,without leaving the joint too dry. Another benefit is the help it provides with diagonal placement. But you have to put the right gusset in first or it will move the diagonal in the wrong direction. Add wax paper between nail head and the gusset, because sometimes the glue can seep back in there in the fury of glue-ition. Hope this helps...somebody.. :) Robert Covington ------------------------------ Date: Mon, 27 Jul 1998 03:06:59 -0800 From: Robert Covington Subject: Re: KR: Progress update (some dragonfly VW info too) You need >to try the Gusset Clampett technique, I think there is a GIF of it on >Mike's WWW site.

Thanks, Robert Covington ------------------------------ Date: Mon, 27 Jul 1998 08:18:10 PDT From: "Edward Newbold" Subject: KR: My Columbia visit Hey there, guys. It was really neat meeting all of you NetHeads down there. I only wish I could have arrived a little sooner so I could have enjoyed the tour and talks. As you might or might not know, I left Columbia at 8:30 sunday morning because I wasn't too sure how the weather was going to go. About 12 miles south of Lebanon, TN, at 4,000' my Traumahawk's engine started running very rough, as if I had lost a mag. I watched everything *very* closely as I proceded to make a precautionary landing at M54 (Lebanon). I made an uneventful landing, and the FBO guy and I checked everything we could possibly check on the Piper, and found nothing wrong. However, we both noticed the fuel had a very strong acetone-like smell. As I had refueled last at Maury County Airport, we thought perhaps they had a tank of old fuel there. I don't know. Maybe. I did, however, thoroughly run up the engine, went to as lean as possible to burn out any crud that night be in there. I made a normal takeoff and flight back to Columbus, OH, without any further difficulties. Crap like that sure keeps you *awake and alert* for the remainder of the day though! Thanks very much, Dana, for picking us up at the hotel and returning us to the airfield sunday morning. It was great hearing about the A-Team too! Lotsa luck with the effort. I look forward to hearing much more about it. See you all at OSH this week (or weekend)!

Then ground off all the sharp edges and drilled the needed holes (o*lite bushings too but thats another story). Everything looked great. When I slid the 1" inside the 1.25" to see if it would fit it seemed a little tight but I figured it would "break in" with movement. So I assembled them onto the spars, put in the hinge pins, and proceeded to wiggle my elevator up and down as it will eventually do. Then came the problem: the more I wiggled it the tighter it bound up. What could be causing that I wondered? Definitely unacceptable. So I took it apart and found deep scratches and bits of aluminum between the flat rubbing surfaces. So here is my analysis of the cause of the problem: The channel material fit together too tightly and even a few thousanths wont rub off nicely as I had hoped. Sooooo..... I got out a fine sanding belt and took off a few thousanths from both the male and female hinge pieces (4 surfaces in all) until the pieces fit together to perfection. This seemed to cure the problem and I hope that I have not sacrificed too much metal. So the moral of the story is to try to get "c" channel that doesn't fit together too tightly. Hope this helps some of you.

I got my material from RR so I wonder if its an issue with all of the C channel used for hinges? I was looking through the AS&S catalog and found what looked like perfect hinge pieces in the ultralight section. I will check the page numbers tonight but the little pieces were already cut and drilled and were like $4 ea. If anyone is interested I would be glad to buy a couple and let you know what I think. I think the material was 6061 t6 or? - -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290,..
