Rich, that's the plan. I have several different versions of this drawn up, but the one that fits stock spars the best so far is the 47.5" chord version that I'm using on my KR2S. It's an almost perfect fit for the original spars. Were I building from scratch, however, I'd go with the 18% airfoil which allows you to make your main and aft spars taller and lighter, as well as giving you a lot more wing tank area. Troy Petteway is maybe a month away from flying his plane again with the AS5046, and after that I'm sure somebody somewhere will be selling templates for this airfoil, as well as the others. For you more adventurous souls who think you can draw up and plot out a set for cheaper, the coordinates will eventually be published on Selig's web site, as they will be public domain at that point. But be advised that the going rate to plot out ONE E-size sheet is about $35 at your local plot emporium.

There is a new email virus called melissa, or more properly, W97M.Mailissa. This is a Microsoft Word Macro virus and could ruin a lot of work for anyone who uses MS Word for your business or pleasure. You can find all about W97M.Mailissa at the following location: http://www.symantec.com/avcenter/venc/data/melissa.html Anyone who wants the full text of this location, and can't get it themselves, you can send me an empty email with the string "request melissa.txt" in the subject.

I seem to recall Aircraft Spruce has a combo S2 fibreglass and uniKevlar tape 12" wide, made specifically for epoxy to whet out the kevlar. In addition, the combination has better properties than either constituent alone. Has anyone tried it?

Sounds like you made a roadster out of it.. On a different airplane, I used one of the fisrt gas springs, and it was very sucessful. 20 years ago. At one point I taught the people from what is now "The Airplane Factory" in Dayton, Ohio. Look in Sport Aviation. Last year, I bought a KR2 Canopy from them. The problem is that shipping to England will be very expensive. If you can find anything close locally, you'd be surprised at how flexible they can be..Also, with a bit of effort, blowing one is not that difficult. Actually, it's sucking with a vacuum sweeper that does the best job. -----Original Message----- From: bounce-kr-net-19348@telelists.com [mailto:bounce-kr-net-19348@telelists.com] On Behalf Of Dave Wallis Sent: Monday, March 29, 1999 3:49 PM To: KR-net users group Subject: [kr-net] Canopy needed for KR2 Hello KR-netters Has anyone got a canopy suitable for a KR2 as ours has met with an unhappy end If you know of one, please E-mail me with price and condition PS - If anyone knows of a good canopy restraining strut design I would also be interested - Prevention is better than cure.

Hello, Mark It's been a long while, almost two years since I left the KR-net list. I was reading the KR-net digest (looking for some info) and decided to drop a line. I have checked up on the gang from time to time: yourself, Mike Mims, Ross, etc. Nice to see the projects evolving. I also have seen Lionhart's in the aviation press; impressive! Congratulations, it must be exciting being part of such a project. I joined the Zenair list after I left KR-net. I acquired a set of plans and started setting up shop a few months ago. The first parts should come out of the "assembly line" a few weeks from now. There is no target date for completion: I'm in no hurry. My site is out of date, I haven't done much to it in 16 months. I'll redo it when I have something to show, like real aeroplane parts. Please tell the gang I say "hi!".

Wadleigh" Date: Mon, 29 Mar 1999 22:13:04 -0700 X-Message-Number: 15 Thanks to Mike Mimms for input that I have not heard before. Are you saying that west system is not as strong as other epoxies? Please expand on this. As far as the nonwetability of kevlar, I have contacted the manufacturer of kevlar - they state that a technical advisor will be in touch with me in a day or two. I will let everyone know what they say. As far as practicing with composites, I get a small rectangular piece of scrap masonite, and glue on 1x1 strips of nonaircraft wood to make thin box with a back (similar to the sides of the KR). I the fill in the box with foam purchased from aircraft spruce. I then apply the composite material and laminating system. This will see how well the composite adheres to wood and foam - both important with KR'S. Again, I hope this is helpful to others. And if anyone has any info to help with our learning curve, please do so.
