From: "Richard Parker" Date: Sat, 13 Mar 1999 09:20:32 PST X-Message-Number: 1 Just finished my spars. I'm trying to decide if I should install them now or not. My garage is small and I'm afraid it will make getting around tough. It will however give me the ability to finish the seat and sit and make seriouse airplane noises though. Would you guys recommend making the inner and outer ribs and glueing them on as I install the spars? any other hints? (I hope the new KR-net generated business partners arent going to hold back info so that they can make a few $$ on it :-0 ) Rich Parker richontheroad@hotmail.com http://top.monad.net/~theparkers/kr.htm Jaffrey, NH Get Your Private, Free Email at http://www.hotmail.com ---------------------------------------------------------------------- Subject: Re: Altimeter Formulae - Be Careful!

These are real airplanes and uncaught failures of any part, be it a faa pma approved part or a part from the local hardware store as some of you are using, could result in a nervous situation at 160 mph with nothing in sight but trees at the end of the runway!!!!!!!!!!!! ---------------------------------------------------------------------- Subject: fuel tank calculations From: "Christopher Stewart" <23cs@msn.com> Date: Sat, 13 Mar 1999 14:35:11 X-Message-Number: 4 i need help in designing my fuel tanks for my KR-1, i want to put tanks in the stub wings and to the best of my full size drawings i am making so far i have the aprox. dimensions 10.5 wide x 21 long x 7 behind the main spar and 3.5 in front of the aft spar, get the picture, the tank takes a 3.5" slope to the rear, is there a calculation to figure out the exact or close to the amount of fuel the tank can hold?, any help would be nice, , and mark, i would be very interested in buy stuff from your newly formed company, RR prices are too much!!!!

Measure the area of one of your sides, then multiple by how long. Divide this number by 231. Then you have gallons. -- 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: fuel tank calculations From: "Mark Langford" Date: Sat, 13 Mar 1999 19:09:27 -0600 X-Message-Number: 6 >i have the aprox. dimensions 10.5 wide x 21 long x 7 behind the main spar >and 3.5 in front of the aft spar, get the picture, the tank takes a 3.5" Christopher, 10.5[21(7+3.5)/2]=1157 now divide by 231 gal/cubic inch and you get 5.01 gallons per tank. Mark Langford ---------------------------------------------------------------------- Subject: KR progress and misc stuff From: Kerry Miller Date: Sat, 13 Mar 1999 19:25:40 -0600 X-Message-Number: 7 Finally, another progress report. Today I built the fairings around the retractable gear and did the fiberglass lay-ups on them. I'm not totally satisfied with them yet, but I'm getting there. I know now why the fixed gear is as fast or faster than the retracts - it's tough to fair them in the way they are designed. Has anybody tried putting some little rubber flaps around the gear legs or anything like that? If anybody has any pix posted of how they made their fairings for the retracts let me know and I'll check yours out. Also, I have a new e-mail address and have unsubscribed and resubscribed to the list with the new one: kmiller01@ticnet.com My web site has also moved to: http://www.ticnet.com/kmiller01 Last question - Does anybody have or know where I can find a manual for an Icom IC-A21 handheld? I'd settle for borrowing one so I could copy it. I mainly want the programming instructions and pinout for the power connector on top. I think I found a deal on one. It has a CM-12G pack on the bottom, it is for AA batteries? I guess that's enough wasted bandwidth for today. As soon as I finish my roll of film I'll post more pictures of the bottom of the wings and the landing gear.

Shoulda been: 10.5[(7-3.5)/2 + 3.5]21/231=5.01 gallons Sometimes you wish you could take those emails back, don't you?

From: "andy picklesimer" Date: Sat, 13 Mar 1999 19:41:33 -0800 X-Message-Number: 9 Hey KR netters. This post brought to mind an airfoil program I have been messing with for a friend who is building a tapered wing all metal design. Compufoil, by Eric Sanders (search "Compufoil" to find the websight), does an excellent job of plotting airfoils and creating templates for cutting foam. I am also using it to make templates for bulkheads just by fooling the program into thinking the aft fuse is a wing with different root and tip airfoils. There is a trial download on the site that won't print, but will let you play a bit. Once you buy the program, you can input the coordinates from any airfoil known and create from model sized to 150" long ribs. The program only set me back about 85 bucks. It was made for models, but I overlaid an aifoil I created on the program over one an engineer buddy of mine drew, and we were right on. Sorry about the long note. Email me a pickles@snowcrest.net if you have any questions about what we are using it for. -----Original Message----- From: Richard Parker To: KR-net users group Date: Friday, March 12, 1999 11:46 AM Subject: [kr-net] Re: Trailing Edge Technologies, LLC... >Good idea, I'll buy stuff >You are never going to get that KR finished now ;-) > >Rich Parker > >>From: "Mark Langford" >>Reply-To: "KR-net users group" >>To: "KR-net users group" >>Subject: [kr-net] Trailing Edge Technologies, LLC... >>Date: Fri, 12 Mar 1999 12:13:30 -0600 >> >>KRNetHeads, >> >>Contrary to my earlier sermons, I'd like to advertise a little.

From: Michael Taglieri Date: Sun, 14 Mar 1999 00:49:07 EST X-Message-Number: 14 As some of you may remember, I was looking for a garage in the NYC area to build a plane. Tonite a friend on Staten Island told me that the superintendent of his apartment house has TWO garages available for $75/month each, which in New York City terms is virtually free -- I've been quoted $130/month in Manhattan just for enough space to keep my motorcycle. The only problem is there is no electricity in these places. Has anybody ever built a KR without power, and is this a practical option?

You can build the boat with a hand saw and a few hundred clamps. Get yourself one of those razor sharp Japanese pull saws and you will be in business. The power disc sander for the gussets was sure nice though. You could consider the plywood gusset method, it may be easier with only a hand saw.

Haven't heard it mentioned since. It seems the Plywood method would be a whole lot simpler. Let's hear it from anyone who knows from using either or both. I may start a "boat" soon.
