Does anyone know (not read from the plans, but know from actual flight test) what the stable CofG range is for the KR-2 and what is the speed envelope for this CofG range?

It'd be accurate. Regarding the disagreement you have with me about KR cruise speeds. You can go right on telling yourself that the typical KR will cruise at 180 but you'll just be kidding yourself. You keep talking about Troy. Troy is the exception, not the rule. Besides, I spoke with Troy at Sun-N-Fun and he pointed out that while he can make 180mph, but he runs the engine at near full throttle all the time and has to let the speed creep up. 3600rpm and waiting is not what I call a typical cruise power setting and procedure. This sounds closer to a max effort. Don't get mad, there's no question a reasonably straight, clean and light KR will cruise at a more typical VW power setting of 3200rpm in the 150+ range. You mentioned 155 indicated at 3100rpm-sounds pretty good. There's also no question that a KR should run away from my Sonerai. I was just relaying that of the two KR's in the area, neither have. A max effort for me right now yields about 150mph. All I was saying is that RR is misleading people into thinking that MANY or MOST KR's built are CRUISING at 180mph and that simply is not true.

If so, the strakes go at the fuselage/ hor. stab point.

It's all right there in the book! Good reading, Dennis :-) ------------------------------ Date: Sun, 08 Jun 1997 10:23:20 From: brian whatcott Subject: Re: KR: High Speed in KRs This sounds like a reasonable, practical question, but I'm going to nit-pick. What is the 'stable speed range?' For any airplane the (flying) speed range is from stall speed to never exceed speed. (Actually for production airplanes, the test pilot demonstrated a few percent more than Vne). But you said STABLE speed range. For US built production civil aircraft, that corresponds with the Vs to Vne range mentioned above. But we are referring to an experimental type. Because the KR developed from the Taylor monoplane, we know that its ancestor was stable thru the range - that's because the bad old FAA equivalent in Britain won't license planes that aren't stable. Here, we can add a little width here, add a little length there, add a little weight over there. That's called FREEDOM! But it makes KRs a variable commodity. OK, but you asked for actual values for actual planes. That runs us into another problem. DO you know how to measure stability in even one axis? Do you know the difference between static and dynamic stability? Do you really think every pilot who gets through to first flight day is an accomplished test-pilot too? I think that's asking for too much. That's why I don't think your question has a reasonable straightforward answer.

It may be tough to isolate them from vibrations, but maybe a layer of foam rubber underneath would help with that.

I need to do my BFR in July. Good thing you can't really fail a BFR, cuz I still am not sure about the alphabet airspace and clouds. Gee, I just stay away from the darn things. Ross, If you have never flown a tail dragger, just go into knowing that you have to "dance" on the pedals. quick movements then back to neutral. If I can do it, most people can.

Ross My experience with sticky stuff has led me to use WD-40, or Zippo Fluid. I'm not sure of the key ingredient in it, but I'm sure it's Flammable! If you let it soak in for a while, you can remove most of it with a rag by scrubbing. That reminds me of a tip - The last time I bought a new pair of glasses, I was told by the optomitrist to ONLY use cotton cloth and NOT to use paper towels or a paper based product. They say that the wood fibers in the paper towels are much more abrasive than the cotton fibers. I'm sure that if it's true, but the same would probably go for the Lexan, Acrilic, Plexi, or whatever is used for these canopies. I'm sure that they're much more prone to abrasion than glass, and really hard to keep looking good. - -- Vince Bozik - Athens, Georgia Mailto:ICBM@ix.netcom.com ------------------------------ Date: Sun, 8 Jun 1997 21:42:57 -0600 (MDT) From: Ron Lee Subject: Re: KR: Duct Tape Removal/Cleaning Canopies > That reminds me of a tip - The last time I bought a new pair of >glasses, I was told by the optomitrist to ONLY use cotton cloth and NOT >to use paper towels or a paper based product.

That reminds me of another hint. My taildragger instructor says to ONLY use Bounty paper towels since they have no grit in them to scratch plexiglass. Of course you could use old t-shirts.

I have purchased but not yet picked up my canopy. My Question: Should I get clear or tinted. I have narrowed My choices to either clear or Light smoke grey. Will the smoke cause problems at night or overcast days? If using clear will it cause undue amount of glare? I would appreciate any input from you flyers out there.

Today I helped him roll it out then I went up in the tower to watch his high speed runs. Controller was kind enough to let me up there and even use his binoculars. Great view ! Quite a sight, tailwheel coming up and it just roaring down runway on mains, Jeff says he took it up to about 50mph and while I didn't notice it, he says once the mains did come off the pavement! He made 3 or 4 runs and took a break - the adreneline rush offered him coffee and he declined saying he was too buzzed on driving the plain to take more caffiene!!! Then the weather blew in and we had to cut it short. But it was indeed a memorable day.

It doesn't remain stuck (and I hope he is right). You can also polish plexi to remove scratches, starting with fine sandpaper and working through the grits to polishing compound. This could remove tape residue in a brute force way. - -- Don Reid donreid@erols.com ------------------------------ Date: Mon, 09 Jun 1997 07:09:47 -0700 From: Micheal Mims Subject: Re: KR: kr2/kr2s design comparing At 06:36 AM 6/9/97 -0400, you wrote: Say this reminds me, if we follow the sketchy plans about >engine mounts, pickup points etc., does anyone know what the max hp is recommended? The "S" is beefed up a little more in the motormount area and the plans say a O-235 is max, these engines (the good ones) can make 120 hp so that's where I am drawing the line. A larger strake in the vertical may be in order! _______________________ ~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Just Plane Nutts mailto:mimsmand@ix.netcom.com http://www.netcom.com/~mimsmand ------------------------------ Date: Mon, 09 Jun 1997 09:51:30 -0600 From: Robert Lasecki Subject: Re: KR: Tiedown Janssen Craig wrote: > > At 01:04 AM 6/4/97 EDT, you wrote: > > > > > >On Tue, 3 Jun 1997 19:29:39 +0000 Robert Lasecki > > writes: > >>There is an excellent tiedown method shown in the Diehl wing > >construction > >>video which uses inexpensive boat fittings which are also lightweight. > >The > >>video shows how and where to put them.

Thanks. > > Ed Janssen Ed: It took me a bit to actually check into the parts recommended myself. Dan recommends using boat bow eyes through the lower cap of the forward spar located between the last two outboard vertical spacers. A hole is cut in the rear web and the 3/8 nut floxed in place. This installation is best done before the wing is closed. He recommended getting the bow eyes from WalMart. What I found is a little different. I bought a pair of truck "anchor points" which are streamlined eyes with a flat base and use a 3/8 bolt for installation. They are made by Highland and sell at our WalMart for $8.00 a pair. The eyes themselves are chromed steel and only weigh 2.2 ounces each.

I can't move the cowel back any further because of the exhaust system, so I am left with having to put a spacer between the prop mounting flange and the prop. It has to be about a half inch in depth.
