KR>has anyone had experience adding span to the horizontal stabilizerafter its finished?
>My guess is that the people that have a problem with the pitch sensitivity either have their C.G. to far aft, their sticks are to short, or they have been flying spam cans to long and haven't taken the fifteen minutes to get used to a KR.< That is the absolute truth. I am not even a student pilot yet (hope to start next year) but I tried flying (landing) the KR in Microsoft flight simulator a while back and crashed.. tried again and crashed again. Went back to landing 172s many times without any suprises. Then practiced on a Tiger moth and a some other tail dragger I can't remember the name now (not had my coffee yet :)) and now I can land the KR with not trouble. Not perfect yet but getting there. Moral of the story just needs a little practice and getting used to. (In case someone missed that all of my flying is in a simulator :)) Cheers! Ameet Savant asav...@notes.state.ne.us
KR>attachments?
Typically "winmail.dat" attachment is found if the email sender uses Microsoft outlook to send the mail. It is not a virus... but Larry and Mark are correct... just do not open it.

KR>Non KR related
Dear KR netters, I have seen this all too often. Someone emails a non-KR related email and 10 people flame that person trying to make an example out of them. Personally, I enjoyed reading the story that was emailed as much as I enjoyed reading the flames! why? because it came from someone who shares the same interest as me- aviation and KRs. I suggest that when a person sends a non-KR related email (does not happend too often) they append the word "NON-KR" to the subject line. That way the flamers can setup their email filters and ignore the emails that bring out the flames. What about the people who forget to append the magic word? Well, I think the list moderator (Mark Langford, isn't it?), or an appointed list member should reply to the offender(:)) ONLY reminding them of the protocol. Is this email non-KR? yes Is this email non-KR-LIST? no ... well then I am sending it :) Thanks!

KR>grain orientation
Oscar wrote: Grain orientation really doesn't have to do with how the spar will fail or crack. I thought wood was easier to break/crack along grain than across grain. i.e. a thin long strip of wood with the grain oriented width wise is more likely to fail than a think long strip of wood with the grain oriented length wise. I could be wrong, but something didn't add up with Oscar's statement. Ameet Savant asav...@notes.state.ne.us

KR>Carbon Fiber
Justin Wrote: >Has anyone used Kevlar, it is a tad cheaper than carbon fiber and said to be stronger and lighter than carbon >fiber. Kevlar is not as strong when loaded in compression. It is mostly used for impact resistance rather than structural applications. Replacing fibreglass or carbon fiber with Kevlar is not a trivial excercise and requires appropriate design considerations, especially in heavily loaded applications. Hope that helps.

KR>GE LEXAN SLX
Dear KRers, Some time ago I requested a few samples of GE's LEXAN SLX Film. Lacking any knowledge about this stuff for finishing composite airplanes like the KR. I thought I would turn you guys loose on this to comment. The following link should give you the promo/data sheet on this stuff. However, I still don't know how to use this. But something tells me that this might an easier way to finish firberglass than the tradiational methods. http://www.gestructuredproducts.com/sp/content/library/pdfs/alit126.pdf"; target=blank>http://www.gestructuredproducts.com/sp/content/library/pdfs/alit126.pdf Enjoy!Ameet Savantasav...@notes.state.ne.us
KR> Static margin
Neutral point (NP) of the airplane can be thought as the aerodynamic center of the plane. It can be derived by some simple math and is dependent on the amount of lift (positive or negative) and the position of the lifting surfaces. So in other words, how big is your HS and wing and where they are. For stability the CG of the plane should be ahead of the NP. When the distance between the HS and the wing is small (short couple) like in the KR the NP is close to the surface with the higher lift (the wing) which leaves less static margin for the CG and hence the inherent pitch sensitivity. There are many solutions to this: Make the HS bigger and/or extend the tail? Put a heavier engine? But remember everything comes at a cost and any changes should be made with care fully addressing the effects that change will have. Just as a FYI, if you make the aft flying surface bigger than the front (canard design) then the NP moves a lot aft and your static margin increases. However, like I said before, everything comes at a cost. Back to the fox hole.

(fit a bigger engine, put on more weight???) Daz, Actually it is not the elevator. It has to do with a characteristic that I have heard called "short coupled". This has been defined to me as the distance between a point on the main wing ( I don't know what it is called) and the same point on the horizontal stabilizer, and the relationship that, to the mean chord of the main wing. So you could have a plane that looked to have a short distance between the two wings and it not be short coupled because the mean chord of the main wing was very short. I hope someone with more aeronautical engineering knowledge than I have, will explain it better. You can offset the C of G by moving the engine out farther, or put on a monster engine. However, your results will vary. N64KR Daniel R.

KR>problems with KRnet? Yahoo
>I would definitely support going across to yahoo groups. >Phil Maley >Perth Australia Before we make an decision, one thing to consider is the file upload feature of Yahoo. Yes, it is true you can upload files for everyone to look at with a generous amount of space. However, to look at the files, you need to have a "Yahoo email address". That email address needs to subscribe to the mailing list as well. I don't think all of us want to get one just to use that feature. So any weight that feature adds in our decision, is non-existent.
