For some reason that message did not get to this email account. I wonder how many other krnet messages I am missing? Regarding your question, When you have Outlook open with a mail folder selected the menu items are: "File Edit View Favorites...". Under View there are two options about half way down on the long menu. they are "Preview Pane" and "AutoPreview". Both work as toggle switches and open messages in that folder to allow you to preview them. I haven't seen much on it lately but there were a series of virus/worms that took advantage of a vulnerability in Outlook that was exposed when those options were turned on. You might want to try both options on a folder with just a few messages that you trust to see how they work. I get this and other similar information from the Navy/China Lake information security offices. They also often include pointers to security web sites. A couple of my favorites are: https://teamvpp.navair.navy.mil/hotohype.htm and https://teamvpp.navair.navy.mil/hoax.htm Another I just received last week so am less familiar with is: www.iss.net and https://gtoc.iss.net/viruses.php Brad Glasco aka klodhopper _______________________________________________________________ Get your own FREE email account at iVillage.com! http://webmail.ivillage.com <-----Original Message-----> > > From: Glasco > Sent: 4/3/2002 8:13:49 PM > To: krnet@mailinglists.org > Subject: Re: KR> YOU CANNOT SEND ATTACHMENTS ON KRNET!! > > Also, if you use Outlook for your mail program turn off the preview feature > for every mailbox.

I personally would simply make the wooden wing spars longer, and extend them all the way to wherever it is that you want the very tip to start, by buying spar material that's long enough, or by judicious scarfing of the caps. I'm not a big fan of the hoaky foam spars. I suspect that they are somebody's kluge job, which was adopted by RR to enable them to sell the same wood kit for both KR2 AND KR2S spars. I would certainly be leary of making the foam spars any longer than the 12" that the plans call for. The end of the plans-built wooden spar is suitable to support more load than we're asking, and it could handle a little more. If you have to ask how much more, you probably shouldn't do it without an analysis. 18" per side is a long way, and I'd do some structural calculations before I went down that trail. Of course, I personally am making my wings a little SHORTER, but you may have a super-low landing speed in mind. It will limit your top speed though, and give you a rougher ride in less-than-smooth air, and force you to go slower during real turbulence. But that's entirely your choice, dependent on your goals...

I was ASSsuming that he was building a new KR2S, like most of us here, which would have meant that he would be adding 18" to the existing foam spars, but upon digging through old emails, I suspect he already has a KR2 (not S) that's already built. He didn't specifiy. If that's the case, the plans call for 18" of glass-wrapped foam spar on the KR2S ANYWAY, so it would not be a problem since there are lots of KR2S's already flying that configuration, assuming you did it the way the plans call for. What I was pooh-poohing was adding another 18" to the already hoaky foam foam spars. I'm still skeptical that the wing skins (per plans, with one layer of KR glass all around, except the leading edge) with no spar inside could stand the loads. I realize that you went on to describe how you'd do it with several layers of glass, but that's not the impression you'd get from the sentence above. > To create your tip extensions, hotwire foam to the air foil profile. You realize that he's going to be using urethane foam (you didn't specify any different, and the plans call for it, and that's what he'd have on hand), and that hotwiring IT could easily kill him from ingestion of cyanide gas even if done outdoors? I just did my wingtips a few months ago (only 6" long past the 80" long wooden spars), and merely glued on some urethane foam to my plywood outer rib, sanded to shape using the existing wing as a guide, and covered the whole thing with two layers of carbon fiber to handle the inevitable "helper" pulling on the wingtips. I just got Rick's second message, and if I had a 670 pound KR with an 0-200 in it, extending the wings would not be a priority of mine. Like I said earlier, unless you just want to land slower, I wouldn't do it. If you want to land slower, you should find a 2100cc VW engine to lighten it up, and if that's not slow enough, THEN extend the wings. I suspect that most folks who put an 0-200 in a KR2 have the need for speed, however. Lift for the sake of lift is a non-issue, as exhibited my Marty Roberts' "homesick angel" performances at the Gatherings in his 800 pound-or-so KR2 at the Gatherings...

I contacted Ed Sterba and he gave me some perimeters to work from and = then I downloaded and used the "Prop Design" software program and then I = ran some numbers on the "Propeller Tip Speed Calculator" to try and come = up with the dimentions for my new prop. The one software program that I haven't found yet is one that will give = me an approximation of how much engine torque would be required to turn = a propeller at a given rpm, of a given diameter, of a given pitch at say = a standard atmosphere.. It would be a natural for a home computer if there is such a program or = if some bright person could design one. I'm trying to find someone who is "flying" a 2600cc VW engine that might = be able to give me some real world numbers and I'm getting a few leads, = thank you. But this is what I've come up with so far. Ed Sterba suggested a diameter of 52" to 56" depending on landing gear = type, so I chose 54", and a pitch of 50" to 54". The "Propeller Tip Speed Calculator" indicates that I should turn a prop = with that diameter at 4200 to 4300 rpm. (kinda fast I think for cruise = but not for red line maximum)=20 My engine is rated ( according to Steve Bennet at Great Plains ) at 90 = hp at 3600 rpm with a peak torque of 155 ft. lbs. at 3400 rpm. So, with these figures in mind, I used the "Prop Design" software to = come up with a propeller that is 54" X 54" which will give me a cruise = speed of 165 mph at 3400 rpm which is at the peak of my torque curve, = and if I put it in a shallow high speed dive or flyby, I would red line = at 4300 rpm which would be about 220 mph which is over the airframe red = line of 200 mph. Now, if I knew how much prop 155 ft. lbs. of torque could swing, I might = know something. If any of you have any thoughts on this subject, I would be glad to here = from you. Thanks, Torquer. ------=_NextPart_000_0021_01C1DC10.8719FFA0-- ------------------------------ Date: Thu, 4 Apr 2002 20:58:30 -0600 To: "'KRnet'" From: "Larry A.

If you try to mix it BY VOLUME in this state, the ratio will be way off! Solutions are; a) Fluff it up again with a paint mixer in an electric drill, to recover the original volume OR b) Leave it in it's "non-fluffy" state but mix it by weight with a micro-scale.
