In the plans where making the wing-attach fittings is discussed, there is no mention at all about hardening them, so presumably Ken Rand intended them to be made of normalized 4130, which is apparently the way Wicks sells the material. Therefore, the question is whether 1/8" 4130 steel strapping 1 1/2" wide would be bendable by a human being of normal strength. If so, the latest stock R-R may be selling may be what the plans call for and the earlier ones may have been made stronger than needed by that vendor. Does anyone have some 4130 stock lying around that he wants to try some arm exercises on? Of course, if there is no downside to hardening except the cost, maybe hardened fittings could be made of thinner stock than the plans call for, saving some weight.

Do you want to hear this? First, relax completely - OK? OK. If we are talking of elastic bending - say a few degrees and the material springs back - no permanent deformation: then it takes just as much force to bend yer average chinese recycled mild steel cut off of a metal can of candies as yer chrome molybdenum manganese super duper vacuum processed heat-treat, precipitation hardened irradiation hardened steel strap SO LONG AS the straps are both the same width, the same length, the same thickness.

If you had used those in your plane it would have failed. The plans are based on normalized 4130 steel. If they had a chrome-like finish, either the plating operation was grossly incorrect, or they were not made from 4130. The edges must be smooth in all respects, and all of the holes should be chamfered slightly (take the sharp edge off). Anything less is a failure waiting to happen.

I purchased new Type IV heads from MOFOCO. These were made in Spain. I had MOFOCO fly cut the heads for 103mm pistons and they installed new valves and seats and springs. I had a local VW hot rod machine shop (NW ConRod) check them out to be sure the valves were done OK. He had to touch up the fly cut because it was so rough. The retainers on the valve springs were replaced because he has had ALL of the retainers on heads from MOFOCO break. He showed me several heads with broken retainers.

Well I've tried to squeeze as much work on the KR as I can during "tax season", OK, I'm a CPA. I know, people don't like to see me this time of the year, unless they're getting a refund, and then it's "do you have rapid refund", too which I reply "Run to the mailbox".:-) I got my intercom and com radio (MX11) wired up and working. This was an adventure as I bought both of these from a salvage shop about an hour away and the wiring harnesses had simply been cut during the removal process. I got hold of both the manufacturers and they were kind enough to send schematics. This little procedure took some time. I wired the entire thing using 2 conductor and 3 conductor shielded wire with push/pull breakers for every circuit over 1 amp. Now when you throw the switch, lights come on and things happens, it's pretty cool. I did wire in a CD player as the intercom is a stereo panel mount. I figure Meatloaf - Bat Out of Hell CD ought to do the trick, or maybe the Top Gun CD-dreaming already. I have been able to talk on the radio to a friend of mine while he does his aerobatic routine in his YAK above the house here a couple of times, it really is fun. I got all my engine parts yesterday from Great Plains for the 2180 upgrade. I have painted the case after etching it with an aluminum mag etching spray from the auto parts store. The speed shop in town turned me onto this product, it worked great. I used oil based flat black enamel cut with gasoline. Ross, I looked at that white paint and just about grabbed it, but thought why have two the same. This evening I'll start cleaning everything real good and go buy all the locktite, graphite assembly lube and so on and should have the engine back together by next weekend (if work allows). I have posted some new pictures of the engine and parts on my web page. I got rid of the other engine pictures so these should come up fairly quickly. I posted one interesting shot of the 1835 crank beside the 2180 crank. I did this so you could see the difference in the front bearing off a stock crank and the Force One Bearing used on the Stroker Crank. Big difference. Almost forgot, another milestone, I get to write in my engine log now. Sorry for the rambling, time to kick back and watch the Olympics.

I don't think >you and I together could bend them if our life depended on it,....well maybe >with a BFH! (that's a big hammer) Well, there goes that theory. I was hoping Rand-Robinson wasn't quite as negligent as the initial report suggested. This whole thing is still shocking to me, since the life of everyone who buys their parts does depend on it. I know everyone subcontracts stuff out, and most companies do little or no final testing, especially on low-priced consumer goods, because it's cheaper to just let the consumers return defective ones. On the other hand, when a defective part would lead to certain death for anyone who buys your product, the standard of oversight for your subcontractors should be higher. When Cessna brought out the Model 140 in 1946, it was the first commercial use of the springbar landing gear design of Steve Wittman. Cessna saved a sample of every single plane's gearlegs just in case future tests revealed that some of them were defective. Obviously no one would expect R-R to save samples of all their wing-attach fitting, but it would not be too much to ask for metallurgical tests on every new batch of critical parts. Maybe with the decline of the KR as the hot new design and Rand-Robinson's apparent willingness to coast on their past engineering, they just can't cut it anymore as a supplier of trustworthy parts. This incident may lead to a complete revamping of the way Rand-Robinson runs their business, but if not, I think I will build a plane that avoids using their parts in any area critical to airworthiness.

I will admit its kinda scary but I am sure RR will get all the sold fittings back. RR has been out of fittings for some time now and maybe she contracted out to another vendor while the orders from KB were being processed. I think almost 100% of the metal fittings and such sold through RR are made by KB and I regard his work as some of the best around. I admit this could have been disastrous if it were not for some neandralthalic airplane builder trying to prove how strong he was in front of his wife! (that's not really what happened) I am almost 100% sure RR will be looking at other venders (if in fact there ever is any others besides KB after this incident) with a much more watchful eye. I think its safe to say RR should still remain you primary source of pre made parts if you don't want to build them yourself. PS Mr Whatcott the type of bending I am talking about would be considered permanent deformation, there was no spring in these units. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Building outer wings now mailto:mikemims@pacbell.net http://home.pacbell.net/mikemims Fax 714.856.9417 ------------------------------ Date: Fri, 13 Feb 1998 21:20:42 -0800 From: tomstokes1@juno.com (Wayland T.

And boy there were a lot of D9's and D11.s there. I never counted but would guess 16 easy. But get this. There were also 7 KR's 1----KR-1 retract, now over 17 years old and powered by a Walter Micron straight four. 2----KR-2 retract, one now 16 years old 3----KR-2 fixed 1----KR-2s fixed, now 15 years old (mine). All the 2,s are V.W. powered. Mostly Revmaster 2180.s and two Hapi 1800,s How about that for little old N.Z. Total aircraft attendance was i believe over 200. Public attendance must have been in the thousands with temperatures in the high 20's every day. The show went for three mighty days. Just planes, planes planes. On the way up I flew with a Jodel D9 and a Taylor Monoplane, both which have a cruise speed of 60kts. That made it very interesting as my stall speed is 48kts. That meant for over four hours excluding fuel stops we were in or just above the stall as we slowed down then sped up etc. Mostly the revs were 2200rpm and 12inches.On the return I went direct on my own in 1hr 10min, 125kts@3000 with an average fuel burn for the whole trip of 12lts per hr.

My KR is gona be one ugly unit when it first hits the skies, no paint (if I need to add strakes, farings etc I do not want to ruin a good paint job) and like I said very minimal interior and instruments. Oh well sometimes ugly is good! :o) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Building outer wings now mailto:mikemims@pacbell.net http://home.pacbell.net/mikemims Fax 714.856.9417 ------------------------------ Date: Sat, 14 Feb 1998 13:25:12 EST From: KR2616TJ@aol.com Subject: KR: Mass Mailing. Let's see, Play It Again Overall, We Be KR Parts and Shxx (Stuff). Boy can you tell I'm getting close to done, only a couple of months. I'm starting to get rid of all this "extra" stuff I've accumulated thinking at the time that "I might use that for something". I just mailed out copies of the Traveling Resouce Library to Marvin McCoy, Steve Eberhart, Esko Lempola (Finland, cool) and I'll get Brian Bland's out on Tuesday (I lost his address). If you want on the list, get hold of one of these guys or wait for Oscar's CD ROM, I mailed him my original copies. Ron Dewees, I mailed you the extra copy of the RR Construction Manual, now you'll see where the rest of us are coming from in saying that on some things you just do it the way you think is right and see what happens. Marvin, I sent out that flap handle along with your copies of the TRL. I'll be posting additional engine rebuild pictures through the week and will keep the list posted as to how the 1835 to 2180 Force One upgrade goes. Back to that maybe I'll use that one of these days thing, a guy in my hangar row just offered me a 235 for $800.00 it's in pieces but I believe I'll get something else to play with. He's had it in his hangar for about 10 years and doesn't know what to do with it. I do.

I would think you could remove some material at the upper 1/4" plywood shelf on the sides to contour to the firewall template width. You could alternatly make the firewall a bit wider to account for this, I imagine that the RR cowling might be flexible enough to do 1/8" to 1/4" but perhaps not. If you are planning on doing your own cowling, then you can just make the firewall wide enough to cover, and not worry about this. I don't recall a difficulty here, but may have done some contouring at the upper 1/4" shelf area. -- Regards Ross Alan Moat wrote: > I have been working on my templates for the front deck while waiting > for spring.

Chris, It's always interesting to see another Schlumberger email address on a non business issue... Check out the Matco hydraulic brakes. They were about $450 or so when I bought them. I don't know about run up.. I just didn't like the idea of grabbing the cable at the spar to stop. I figured with one hand on the stick, and another on the throttle, I might not have a free hand for the brakes. I have a hangar mate with a heel brake cable setup, this looks like it might work. -- Regards Ross Chris Gardiner wrote: > Does anyone have suggestions/comments about using the Azusa wheels with mechanical b.rakes.? > > The price of the Cleveland 500x5 's is pretty scary these days. > > I've heard that the mechanical brakes are not strong enough to do a proper run up. > > Any and all opinions/comments appreciated. > > The KR2S sitting in my garage will get it's gear (Diehl) this summer and I need to get some wheels on order. > > Thanks to all the KRNet heads out there.

I felt like Fred Flinstone trying to do anything with this stuff. It took me about a year elapsed time to get all my fittings built to my satisfaction, with lighning holes etc per plans. Lots of work.

I wouldn't be able to SEE the rust. Maybe I'd have to put a 50 hour/annual inspection item to remove the tape and check the pipes. The advantage of cooler cowling temps may be worth it. I could check out getting the pipes plated, but then that makes everything heavier... not to mention more expensive.

Everyone please keep in mind this in not an direct attack on RR I just feel better knowing I have done all I can to make sure these things never make it in the air! I am sure RR will do the right thing. Anyway the URL is: http://home.pacbell.net/mikemims/wafs.html You can see in some of the pictures the edges are not properly cleaned up and something I noticed today upon closer examination is the fact that none of the holes are chamfered.
