From what I have seen on this internet and elsewhere ie. Sport Plane and others, I have not heard or seen many KRs with fixed gear cruising much over 150mph. I am not saying there are not any out there but they are few and not the norm. I recently moved to a new home here in southern Nevada and have been off the net for a couple of weeks so haven't been able to keep up on everything. My bird is getting close to being back in the air again after a new paint job and bigger fuel tank. I also reduced the overall weight by about 50 lbs. These mods should make a better bird out of it and I think will also increase my cruise speed to closer to 170 mph.

I think I was just trying to make the statement that in the evolution of the KR, the retracts have been shed in favor of fixed gear. There is no speed difference and if that's hard to swallow then take a drink of water while reading this post! :o) ________________________________ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Just Plane Nutts mailto:mimsmand@ix.netcom.com http://www.netcom.com/~mimsmand ------------------------------ Date: Tue, 2 Sep 1997 15:07:40 -0500 From: kr2builder@juno.com (Richard E Pitman) Subject: Re: KR: Ricky Pitman Hello All, It is with great sadness that I write this letter. As already forwarded by mike Mimms, I had a heart attack at work last Wednesday night. Fortunately, being a nurse and working in a hospital I was less than two minutes from the Emergency Room. This probably saved my life. Thirty-seven (that's right 37) years old and a heart attack and double bypass surgery. I was already diagnosed as a type 2 diabetic and was fighting that to reinstate my medical. I am afraid that this has finished it for good. Any how, I am home recovering. I have almost everything needed to build and or complete a KR2/KR2s. All will be sold. I had just changed jobs and have no sick days, so no check for at least six-weeks. ANyone needing anything for their plane, e-mail me direct at RNRicky@juno.com and I will sell at 25%off of my purchase price. There are good deals to be had, becaused I shopped hard before buying any parts. Thanks to all. Maybe I will be able to get to the next gathering. I may not be a builder anymore, but I will still feel like part of the family.

The original plans do call for 5 ply mahogany plywood. At the time the design was drawn up, mahogany plywood was relatively inexpensive and readily available. As the trees suitable for aircraft quality materials became scarce the mahogany plywood became an item in short supply, other materials were substituted. 5 ply birch was looked at but was too heavy and had more strength than was needed. 3 ply birch came closest to the mahogany in strength and as a bonus, there was a slight weight advantage. I wasn't aware that suppliers were substituting the birch though. You might confirm the substitution was intentional with them. I'm sure you'll be told much the same as I outlined above.

You can go to my wing page to see them if your interested. One thing about drilling the holes in the spar caps for the attach fittings, build yourself a good jig and take your time to get it right! I have to admit my first two or three holes were less than what I wanted and I had to use flox to fill the holes and then insert the bolts. I am pretty sure the flox filled the excess area around the bolts in the spar cap but it sure felt better to know the rest were perfect! After the first two being off a little I had to re think my technique and then everything went much better! The second time around I used a squared piece of hardwood about 2 inches x 2 inches and drilled a 3/16 hole through it on the drill press. I jigged the fittings and clamped them in place and used the hardwood to keep the bit 90 degrees to the fitting. I marked the bit so I would drill a little more than half way through the spar cap. I drilled from one side and then held my breath and drilled from the other stopping as soon as I felt no resistance (wasn't cutting wood anymore), I think I could have drilled all the way through from one side but drilling from both went so well, I couldn't stop. After all it was working perfectly. I clamped the fittings on the outer edges and drilled the center four holes first. I installed the center bolts and then removed the clamps and drilled the remaining holes. I used a long 3/8 bolt through the main bolt holes to keep things inline. After all the drilling was done I removed all the bolts and coated them with t-88 and reinstalled them. A jig like Mark Langford built would probably be better than the hardwood cube jig I used but I guess there is more than one way to skin a rat, or is that a cat?

With my bracketts I built a metal guide and used a drill press for alignment. Once this guide was fabricated I tapped two holes for bolts that were used for clamping the guide. But, I drilled from one side all the way through. This worked well because I had 1-1/2" of guide at the drill side and hit the hole in the guide on the other side of the spar caps. This was illustrated in one of the Newletters when Ernie was editor. I did not use any resin on my bolts. Main thing Mike, if you feel that you did a good job, that is what counts.

I had been using 3 bathroom scales that I bought at Wally Mart. Guess what- there was a 3 lb. difference. Hardly worth the effort, but I am sleeping better. With the ELT mounted as far back as I can reach, and a little trimming here and there, the final weight is 638'. The C of G with me sitting in it with full fuel is right on the foreward line. After much thought and review, I decided to use 7.6 to 14" behind the inboard wing leading edge. There is an interesting article about this sort of thing in an old newsletter- October, 1990. Written by George Leskien. It is really worth tracking down and reading. Well, I have an appointment with the FAA inspector this weekend. I will keep you posted.

A single, long 3/8" bolt is slightly stronger than using two short 3/8" bolts in the main wing attachment, but only if a compression tubing is installed. The plans show using short 3/8" bolts in what is called "single shear" to serve as the way to remove the outer wing panels. In single shear, the bolt has a slight bending force applied to it. If it is loaded in "double shear", the bending force is removed and there is an increase in strength. BUT, a piece of tubing must go between the wing attachment fittings so it can be tightened. In the KR, this piece of tubing would be as long as the outer spar is wide, and would be inside the outer wing spar attachment fittings. - -- Don Reid donreid@erols.com ------------------------------ Date: Wed, 03 Sep 1997 08:48:13 -0700 From: Donald Reid Subject: Re: KR: major screwup?

The 5 ply is about 10% stronger in some orientations than the 3 ply, but about 10% weaker in others. It is basically a zero event. - -- Don Reid donreid@erols.com ------------------------------ Date: Wed, 3 Sep 1997 10:27:21 -0400 From: "Cary Honeywell" Subject: Re: KR: Ricky Pitman Email (repy) to cary@storm.ca Web page http://www.storm.ca/~cary/ KR2 area http://www.storm.ca/~cary/kr2.shtml - ---------- > From: Richard E Pitman > Thirty-seven (that's right 37) years old and a heart attack and double > bypass surgery.

For what it is worth, if you can keep going on the KR, do it. It is good for the soul. Keeps your mind focused and helps you cope with other things. With today's medicine, your medical may not be gone for good. Take some time before you commit to anything. There is often a stage after major surgery or any life threatening event, where depression sets in. That is not the time to make decisions that you may regret later. If there is any way you can keep on with the project, then do it. Even if your medical is gone, you can, with the help of fellow pilots/friends see your dream take flight. I lost my medical for a year and almost sold my 172, but my fellow pilots insisted that if ever I wanted to go flying, they would go with me. It may not be as much fun as the left seat, but it does the trick. - - Cary - ------------------------------ Date: Wed, 3 Sep 1997 10:32:26 -0400 From: "Cary Honeywell" Subject: KR: Oil or sump'n Email (repy) to cary@storm.ca Web page http://www.storm.ca/~cary/ KR2 area http://www.storm.ca/~cary/kr2.shtml Does anyone know anything about something called "--- Miracle Oil".

I've heard auto and airplane mechanics speak of it in almost mystical tones :o) I've used it in auto engines that have been sitting for a long time and haven't had any problems. Never used it in an airplane engine, but I've heard it's good for old low compression engines running auto fuel. Mixed with the fuel, it replaces the lubricating properties of tetraethyl lead.

However when I used to build boats we used colodial silica mixed with epoxy to mount the bolts on deck for the winch and pad. We would drill a hole about twice the size of the bolt and fill it with epoxy/siliica mix and set the bolt in the filled hole. There is a lot of pressure on a large winch on a sailboat deck. I could pound the silica/epoxy mix with a hammer and it was strong as steel. This was a method that was tested and promoted by the Gougeon brothers & West system. The cotton flox may not be quite as hard as the silica but it should be every bit as tough. Marvin McCoy Seattle, WA.

I think this was a big issue back in the 70s when a few builders installed single bolts without compression inserts. I didn't realize the single bolt was stronger so maybe I will put these long bolts to use!

That's about 30%,....a number most light airplanes use as a aft limit during the initial testing. Good Choice in My Opinion!

This is what I was thinking, I guess not having X-ray vision and not know whether the flox filled the void entirely s what's on my mind! :o) I used plenty of flox and there was lots of squeeze out so I am trying to convince myself its a non issue! ________________________________ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Just Plane Nutts mailto:mimsmand@ix.netcom.com http://www.netcom.com/~mimsmand ------------------------------ Date: Wed, 03 Sep 1997 08:56:45 -0700 From: Ross Youngblood Subject: Re: KR: KR-2 Gear Castings, etc. Micheal Mims wrote: > Whatever!!
