Archangeli" Date: Sat, 18 Dec 1999 10:21:57 X-Message-Number: 1 Hi all. I just joined your group, and very glad I did. Im hoping to start my project in the spring. As the winter progresses, I am just working out details & posible design changes to suit my requirments. This is where you all will help. I have chosen the KR-2S Because it has all the things I need in a small sport class design exept I would like to trade A higher grose weight for less top end. I'm a big boy at 240 lbs and would like do light cross country with a passanger. These are my posible changes, and i would like to see what any one thinks! 1) Adding about 20" to the wings in the form of large rounded wing tips. 2) Adding aprox 25% more tail stablizer surface. Ive heard of many people doing this! 3) Using flaps 4) And last, posibly changing to a higher lift air foil I am going to use a corvair 100 horse eng and still build as light as posible. But any adivise is welcome, because all modification ideas can be more easily changed now, rather than after construction, Right?!! Well Il see what resposnse I get and will listen to all. Thanks guys.

An index to articles in Sport Aviation is VERY helpful. A number of years back John Roncz had a series of articles on designing an aircraft, using Lotus spreadsheets. Should be easy to find those articles now. At one time each December issue held an index of articles, too. Also, thanks for the speed vs. weight calc'n. Jogged my memory.

I know this from direct experience but I am still not finished the project. The KR does lend itself to modification. I am 6'-8" and 230#. I can fit two of me in my cockpit, but I should have a little more width. If I were to do it again, I would make the shoulder width about 43-44" and it would be the widest spot of the fuselage. Any significant design changes can be made, but each change will require careful thought, engineering calculations, and more time, sometimes a whole lot more time. -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ---------------------------------------------------------------------- Subject: Re: Another new KR builder making changes From: "Rick Hubka" Date: Sat, 18 Dec 1999 15:06:32 -0700 X-Message-Number: 4 I thought I's post this to "all" for any new builders and wannabe builders lerking on KRNet... Hi Mike Welcome to KRNet and the world of KR's. My name is Rick Hubka and I'm building a KR-2S also. I've been a member of KRNet for 9 months about the same time I started building my KR. I have just finished the fusalage (commonly referred to as the boat) and will be building my wing spars over the Christmas break. Here are a few KR-2S modifications I am making. My airplane is mostly (mostly ha ha) a stock KR-2S with a couple of exceptions (Everyone does it a little different). I have widened the cockpit area 4" at the top and 6" at the bottom for more shoulder room and less fuselage twist. There is no real formula for widening. Just widen the origional dimensions and let the wood bend to where it wants. You really can't force the wooden sides to be to be at some weird precalculated measurement at a certain point. Just nudge and push the spruce sides around. They will let you know when you're pushing too hard. Up front I widened the motor mount area 1 " to lessen the bending effect of widening the main fusalage. I too will also be installing a 6 cylinder (110 HP) Corvair. I already have the Corvair engine sitting on the garage floor all covered in grease and will be rebuilding it over the next year. I ordered a Corvair/KR motor mount from William Wynns (The Corvair Authority) http://www.omnispace.com/Corvair/ for $200.00 and will be ordering additional parts from him which are required for the conversion. Unless of course, you are a machinest. I will be using the "NEW" airfoil (you'll find lots to read on this subject) and have purchased the WAF's (Wing Attachment Fittings) and the new airfoil wing templates from Trailing Edges Technologies http://home.hiwaay.net/~langford/tet/ (KR builders Mark Langford & Dr. Dean). I'm not supposed to advertise a company name unless it'd friday (Oppsss.) I am using a Dragon Fly canopy. If you widen the fusalage more than 1.5" you should probably go with the Dragon Fly canopy. It is quite flexably and can accomidate almost any width. A big plus to a DF canopy is that it is much more steam line the the stock RR Canopy. I will be adding about 10% more area to the horizontal stablizer surface. I'm really happy with the change choices I've made so far and If I was to start over I might add one station about 14" to the length of the fusalage. I guess after saying all that, I can't really call it a stock KR-2S. Technically after all these changes I can't even call it a KR-2S but that's a whole new can of worms now isn't it.
