Re: Finish work ---------------------------------------------------------------------- Subject: Re:KR interests From: Eugene Israelsen Date: Tue, 07 Dec 1999 19:33:21 -0800 X-Message-Number: 1 Years ago I saw a single seat fiberglass bodied KR2 hangered at Borego Springs, CA belonged to Neal Bingham of Laguna Springs, CA which had a Model A or T Ford carb. He had test run it mounted on a VW 1600 cc which was mounted on his KR. He liked it better than the Posa. I also read an article in Kitplanes?? on canopy building. Instead of an oven they used a plywood box lined with sheet metal or aluminum and placed gas (natural or propane) heaters at specific locations underneath. The exact location would logically be where the most deformation should occur. They let the plexiglass sag under gravity to the desired canopy height. Then turn off the gas and vent the box, but it may have to be done just before the sag is at the desired spot. They said to not blow the canopy because that process sets up stress lines in the canopy which at the proper angle in the sunlight reflects and refracts the suns rays suficiently to make it almost impossible to see out of the canopy. I don't know if Lexan would perform likewise, but it might not be a bad idea to test a blown canopy in the sunlight before mounting. Rule of thumb: It is generally easier to buy than to design and manufacture. Keep cutting, sanding, and glueing. Eugene Israelsen, Hyrum, UT.

Jim Gogniat ---------------------------------------------------------------------- Subject: General info From: "Peter Chevalier" Date: Wed, 8 Dec 1999 8:41:32 X-Message-Number: 4 I am a potential KR-2S builder with a few questions and I hope to gain the collective wisdom of you KR owners/builders. Please forgive my ignorance. 1) AVEMCO apparently is not comfortable with the KR series. The only coverage they provide is liability, no hull or occupants. What have you all done for insurance, or what should I be concerned with as far as insurance? 2) One of my criteria for a plane is removable wings. I know the wings on KR are removable, but is this practical every time you want to go fly? Right now there is a two year waiting list for hanger space at our local airport (not that I could afford it anyway), so I want the ability to trailer my plane home. 3) Is this plane a viable cross-country 2-up plane? It seems that with the gross weight being what it is and with two people and fuel, there is little allowance for baggage. 4) I'd be interested in cost to build and build time also, if anyone is willing to divulge that. Thanks for your patience and responses. Peter Chevalier ---------------------------------------------------------------------- Subject: plexiglass temps.

I will be carrying liability only on my KR. If you are considering a stock KR width, you will find it tight for two people on a cross country. Most people are widening the fuselage by at least 2-3 inches. It is an easy thing to do. Yes, the wings are removable but it would not be something you would want to do on a weekly basis. It is a little bit more of a job than you might think. Someone on this list, at one time, was selling a bracket that allowed you to pivot the wings back, i.e., Kitfox. As far as money goes, it all depends on what you want your airplane to be. There has been some discussion on the net here lately about building them for $6000.00. I'll have about $12K plus in mine. There are enough qualified people on this net that if you do want to change some things, you won't be engineering on your own. Damn nice little airplanes for the money.

Now if I put that 52x48 prop on the 2.2 liter and let it rev up to 4000rpm, I'd get somewhere in the neighborhood of 100hp at sea level with the simplicity of a naturally aspirated setup. Am I missing something here? All the air tubes, oil hoses, and water hoses on the turbo Soob is a bit complex. With the NA Soob, there's three hoses, two for water, one for fuel. I'm trying to KISS a Soob. -Tom Andersen Orlando, FL > "Parley T. Byington" wrote: > > > > Mike > > > > My Kr2 routinely cruises at 160 mph and I have a 1835 turboed vw.

As is usually the case in aviation gross weight is kind of in the eye of the beholder. Most KRs flying now days are well over the published gross. They are simply flying with more powerful engines. Certainly this shrinks the allowable G loading. Just like any other airplane, as your gross increases you need to decrease your maneuvering speed and increase your stall speeds. With that said, there has never been a known failure of a properly constructed wing spar. The only area of concern you need to address is, can you stay in front of the actual aft CG, not the published aft CG. There is not a lot of room anyway to carry much baggage. A good suitcase is about it.

I carry Avemco Insurance on my KR. $1,000,000 liability and $100,000 per seat. $373 per year depending on your flight experience. This is the same coverage I have carried since the first flight in 1997. It is generally true that Avemco will no longer insure any homebuilt for hull insurance during the first 10 flight hours. The exception to this is if you have had an EAA Tech Counselor do a series of 4 inspections and file the appropriate inspection paperwork with the EAA. Avemco will verify that your plane had 4 tech counselor inspections during construction and is willing to sell you hull insurance on your plane. This is Avemco's way of encouraging the use of the EAA Tech Counselor program to ensure that more planes are built to a better standard.

I know many Subaru conversions that cannot outrun a VW installation. My goal has always been 165mph on a 2110VW. Talking to Monte Miller after the latest Gathering, he said his KR cruised around 150mph using the 1835VW and a climb prop. He said that 170-180 was poss- ible with a cruise prop. His empty weight was around 520, if I remember correctly. Keep it simple, keep it LIGHT! ---------------------------------------------------------------------- Subject: Finish work From: "James Gogniat" Date: Wed, 8 Dec 1999 19:41:7 X-Message-Number: 13 I have my airplane upside down at this time doing the finish work in preperation for primer and paint. I have a question for anybody that has done the finish work on the bottom of their airplane. What did you do at the point on the bottom of the wing where the fuselage and wing meet? I see no reason to put a foam and glass fillet here if a nice bead of dry micro would stay in this area without flexing so much that it would fall out. I am open for your suggestions! Thanks.....Jim ---------------------------------------------------------------------- Subject: Re: Finish work From: Mike Mims Date: Wed, 08 Dec 1999 20:04:18 -0800 X-Message-Number: 14 James Gogniat wrote: > I see no reason to put a foam and glass fillet here if a > nice bead of dry micro would stay in this area > without flexing so much that it would fall out. > I am open for your suggestions! >>> I remember reading somewhere that if the filler were over 1/4 inch thick in areas like fillets there should be a layer of light glass over the top of it. I made my fillet on the bottom of the wing by using a tongue depressor and wiping the excess filler away. I would guess the thickest part is maybe 1/4 inch. I know for a fact that there are LongEZs and Dragonflies at my airport with fillets made out of micro that far exceed 1/4 inch in thickness and do not have glass over them. A few of these planes have almost 1000 hours on them and so far none of the filler has fallen off. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Sanding and Filling AGAIN! :o( http://www.fortunecity.com/marina/anchor/270/ mirror @ http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ --- END OF DIGEST --- You are currently subscribed to kr-net as: johnbou@ipinc.net To unsubscribe send a blank email to leave-kr-net-110995W@telelists.com
