Agreed. >I completely agree, that asking questions is a good thing, and I have no >problem giving out all of the information that I can on a given subject, but >designing a safe airplane, and modeling something in 3-D are two very >different issues. Of course they are different. My point was not that they were similar in any way. It was that asking questions is how people learn, and if you are going to deny an answer to a question without giving the basis for it, then you were missing an opportunity to educate, and that was the disservice. What you said may have been wise in its brevity, but it would have done more good to the questioner and others to tell him exactly why you thought that as well. Then it would have been wise, _and_ educational. :) I suppose this issue concerns me because there is a KR in my local EAA hangar that to me, is very substandard in construction. A Cozy Mark IV builder asked me, "don't you think that you should tell him if something is wrong with his plane before he flies it?". My first response, was well, If you had talked to the guy, you would know that saying something wouldn't matter---"I'm a flyer, not a builder" I was told earlier. It is hard to point out to someone that their work may be deficient. In any case, If I am still located there, and things aren't fixed as the thing progresses (he bought it from someone I think), I will certainly point it out. But being a KR, I may just be concerned about aesthetics. It still may be structurally within KR flyable range. But he sure has a lot of sanding to do on those wings...a new brand, CamelBack wings...and I think they used to be Diehl skins. :) >Robert, if you make a mistake, you know about it >immediately, and no one gets hurt (except your 3-D man in the computer.)

So then >somebody gets hurt. >Some poor guy has to sit there and think to himself - I >told him how to plot the airfoil for the wing that failed. (Actually, a 3-D babe :)) But if you had also told them at the same time that changes are wide ranging in their consequences, and here is what you should check beforehand, and what you had better also consider, you have educated,_and_ warned, and any consequences at that point are their responsibility alone. When a newbie shows up on the list, they often throw out a lot of ideas that they have had for awhile. This can give a deceptive impression that they don't care about safety. For some, that is true. But for others, it is just creative brainstorming going on. And some just don't know what it is that they don't know, and are innocent in their intentions. Anyway, I don't mean to bring up old baggage, I just wanted to get these thoughts out of my head. Ultimate blame for anything falls on the FAA inspector who approves the thing. In other news, Boeing reports that any statement to the effect that their 737 tails are defective are of course, rudderly ridiculous.

Here are some thoughts that I have called The Penned Offhandments.

If you want a spar to cuss, make it do more than it was designed for. 2. Weight and Balance - Does more for you than hate and talents. 3. Got Fuel? 4. Balanced control surfaces will leave you with less flutterfly's in your stomach. 5. Don't build two left or two right sides. Unless you are building two planes. 6. Honor your mother and father. Make them test fly the thing. 7. Thou shalt not steel. Particularly if the plans call for aluminum. See #2 8. Do not covet thy neighbor's life. Bring them down to your level. Get them hooked on flying. Then they won't have money either. 9. Thou shalt not keel. You are building a plane, not a boat. Unless you are building a KR. Then you are doing both. 10. Remember the sawbooth, and keep it holey. That way extra sawdust and wood chunks can get out. Robert "Did you set your clocks ahead?" Covington "Hey, dude, what was that bump?"

With all the x-country flying you're doing in your KR you have a lot of experience with this issue. What about dual lap sticks? Yay or nay? I have the RR single stick control and was planning to use a pushrod under my left seat, to a bellcrank behind the seat to the cables. My only concern is clearance under the seat bottom for the pushrod. With 2deg incidence, I'll have room under the rear spar to run the pushrod, but if my butt rubs the pushrod that would cause a lot of drag there. Maybe a hard shell seat bottom, like the dune buggy seat, instead of the sling seat would preclude this from happening. I've heard those glass dune buggy bucket seats offer a lot of comfort and shape. I'm 6' so I have to recline the seat back and sit close to the bottom to get head clearance even on my S canopy. Would a tall S owner relate how much under seat clearance there is at the seat's lowest point? I'm thinking the dual stick would preclude all these problems but it has a bunch of slop and I detest sloppy controls in anything. The KR is so crisp in handling and I want to keep it that way. -Tom -----Original Message----- From: Bobby Muse To: KR-net users group Date: Saturday, April 03, 1999 10:41 PM Subject: [kr-net] Re: Itty bitty update >At 04:27 PM 04/03/1999 -0500, you wrote: >> I can't decide whether to place my single stick in my >>lap or to the side between the seats, offset 1" to the right for a little >>more space.

Tom, Is there any reason that you don't want to attach the push rod in the center of the dual stick assembly? This way the push rod runs between the pilot and the passenger and would prevent you from becoming a "taildragger." I have seen several good plans for a dual stick assembly (Mike Mims has one on his web site,) and most of them show the pushrod to run between the seats for exactly this reason. The elevator control pushrod or cables are one thing that you make sure are unobstructed, or for that matter, are unaffected by anything else in the airplane. The center pushrod would also not prevent you from using just about any type of seat that you wished.

There is nothing as tight as the single stick control (which I already own$). Maybe the fiberglass seats can give me the 1.5" I think I'll need under the seat. I'm very picky about control slop or binding. I like Mike's wrap-around cable for his rudder pedals. That's got to be very sweet in the air and on the ground. Even the pushrod idea could be sloppy without high quality ball joints at each end. My experience as a R/C pattern flier has made me fanatical about slop and friction. -Tom >Is there any reason that you don't want to attach the push rod in the center >of the dual stick assembly?

I just tried that link on Mike's page for the dual controls and it doesn't seem to work at the moment (Mike?). From what I remember though, Mike scanned the earlier one of the two dual control systems that were in the back issues of the newsletters. The later version is the one you want to look at. Built at home, this thing is dirt cheap, and quality rod ends would eliminate any slop that you might encounter - but, you'd have to weld it yourself. If you do decide to run that pushrod under the seat - keep in mind that the pushrod will go up and down a bit as it moves back and forth, although not much (0.4 in,) you have to plan that into your spacing, otherwise it won't allow you to fully deflect the elevator, or worse - it would get stuck. The fiberglass seats might just give you the clearance, but it would depend on which ones you decide to go with. Having built a VW Sandrail, I recall that some of those seats can be fairly deep. The other thing to keep in mind, is that if you start pulling positive Gs, fiberglass seats will deform slightly pushing your backside closer to your control. So, allow for this in your spacing as well. Yep, Wrap-around rudder cables - the only way to go.

As you are aware, I'm building a new rear spar and positioning it .755" above the plans position. I completed the removal of the rear spar today. It was a piece of cake. Using a cold chisel I removed the outer 5/8" blocks first. Moving to the inside I used the same chisel and separated the spar from the vertical members, lower longeron and upper 5/8" piece. I cut the spar in half and pulled it out of the slot. All I will have to do is dress up the glue contact points on vertical members, extend the slot up .755", glue a .755" piece of old spar material to the longeron and glue the new spar in. I'm going to use the laser cut WAF from Mark and Dean and drill the spar using less washout also. I haven't seen Les's WAF, but I can't imagine anything beating those laser cut, powdered coated one's our KRNet guys have. Obviously the major reason for me doing this is to change the incidence from 3 1/2" to 2". Like Tom said earlier today, another benefit is that now your control stick pushrod will have enough clearance under the spar for unobstructed movement. I know there are some of you guys just starting out (and almost finished:-) that wonder was the hel@#$ I'm doing, but the outcome will be worth it and remember, if you are not willing to do something 3 times...............don't build an airplane.

I'm making my own stringered turtledeck and the front deck is unusable because I widened the fuse, so I'm on my own with the canopy height. It actually would help out a little bit for the stretch I have to do on the canopy frame. The Dragonfly canopy is really the way for tall people to go although the 2S canopy cannot be beat for sleek shape and high quality, plus it's lightly tinted.

The nose rib ahead of the forward horizontal spar is 18" long, greatly sweeping the leading edge. I'm adding only two inches ahead of the spar at the tip which will keep most of the area in close to the fuselage, so the bending loads on the stock spars aren't much greater. There's going to be a 5/8" joiner between the leading edges of these nose ribs, and they'll be attached to the fuselage. I'll get some pics when I get it foamed up. I'm thinking of reducing the chord of the elevator about 20% too. These changes worked out great on my 1/4 scale model, and usually scale surfaces and scale mods don't work out because of the differences in Reynolds numbers. I do wish I went with a thicker airfoil on the wing of the model, a 1/4 scale RAF48 isn't worth a damn at takeoff speeds on the model. It's much thinner than most model airplane airfoils. I have decided not to use the styrene foam for the surfaces because I've seen it expand with heat under the fiberglass and cause irregularities at the spars.

This is not the big concern things happen it just seems that if the engine does quit the plane doesnt wanna act right its not like a cessna trim the plane and keep flying they seem to wanna nose down or spin can anyone fill me in on this is it really a problem. and is it better to spend the extra on something better than a vw engine? ---------------------------------------------------------------------- Subject: Re: Itty bitty update From: Mike Mims Date: Sun, 04 Apr 1999 18:53:35 -0700 X-Message-Number: 22 Tom Andersen wrote: > I'm really amazed at the clarity of the 2S canopy whoever made it did an awesome job.>>>> > -Tom If its the stock KR2S canopy the same guy who made the Dragonfly canopy makes the KR2S canopy. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims KR290S (Sky Pig) ,..Building ailerons and sanding the wings... mailto:mikemims@home.com http://www.geocities.com/CapeCanaveral/Hangar/4136/ Aliso Viejo Ca ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: I AM SCARED From: Mike Mims Date: Sun, 04 Apr 1999 19:29:20 -0700 X-Message-Number: 23 SClay10106@aol.com wrote: > > This is not the big concern things happen it just seems that if the engine does quit the plane doesnt wanna act right its not like a cessna trim the plane and keep flying they seem to wanna nose down or spin can anyone fill me in on this is it really a problem. and is it better to spend the extra on something better than a vw engine?>>>>> A couple things to remember. 1) Most flying VWs are homebrewed conversions by people who shouldn't be brewing at all and in the 70s (when the KR was in its peak) VW conversions were much less reliable than they are now. Buy your parts from someone who has been around for a while and you will be fine. 2) The KR is a light airplane for one and secondly is flown with the CG a little too far aft most of the time. Anytime you fly an airplane as light as the KR and with the CG a little aft all hell breaks lose when you lose power. The nose will pitch up and you will lose airspeed vary quickly. If you stall it will take much longer to recover, that's if you recover at all. Build your plane, balance it right and use a good conversion made out of NEW parts. You will do just fine. Remember its almost always ok to be nose heavy but its NEVER ok to be tail heavy. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims KR290S (Sky Pig) ,..Building ailerons and sanding the wings... mailto:mikemims@home.com http://www.geocities.com/CapeCanaveral/Hangar/4136/ Aliso Viejo Ca ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: Palmer's KR Machine Shop From: Paul Eberhardt Date: Sun, 04 Apr 1999 22:51:01 -0500 X-Message-Number: 24 I'm using the stock sling seat, and Les's pushrod goes directly under the middle of the seat, on the centerline of the plane.

The KR glides very nicely with- the prop not rotating. Get the nose down and fly the airplane is the number one criteria "fly the dam airplane first and don't worry what caused it then only if one has enough altitude. Those are bad stories that the nose drops and spins in from the uninitiated and low time pilots. Remember you have control of the aircraft and the aircraft does not have control of you.

This is not a two pilot aircraft. About the only time that you would need daul controls is when you are giving another pilot a ride, besides non-pilots can cause you problems at the wrong time with the stick between their legs. Just my opinion.

Positive pressure on the rudder pedals at all time takes the slop out, even with no wrap-aroung cable. By the way, just how much slop do you build in the control cables?
