The guy who is building the other KR in my shop with me is also working on an Aeronca Chief. He's about to start re-covering the fuselage. Do you have to file a 337 when you cover a certificated plane? After looking at all of his paperwork for the Chief, I'm glad I'm going the experimental route. He's got stc's for a bigger engine and Stitts covering. It's a good thing he doesn't have to fly with all the paperwork, it would never get off the ground... Tnx, Kerry Miller Royse City, TX Full owner of 1/2 of a KR2. ---------------------------------------------------------------------- Subject: Re: side mounted control stick From: CruzJ12@aol.com Date: Mon, 8 Mar 1999 07:42:41 EST X-Message-Number: 2 Thanks Skip!, greatly appreciate your help with the side mounted control stick.

On the KR-2 I think one BID is all that is needed on the tail. Perhaps this is the same for the 2-S. > Also, has anyone actually had any experience with other materials?

Don't try this with carbon fiber as I understand it is slightly conductive. The antenna kit runs about $27.00 from RST and includes all the stuff you need to make multiple antennas. -- Ross Youngblood Pager: (800)SKY-PAGE PIN#895-9073 Staff Technical Specialist voicemail: (800)538-6838 x 1632 Schlumberger SABER Bus Line: (541)714-1754 Corvallis,Oregon mailto:rossy@saber.slb.com ---------------------------------------------------------------------- Subject: Re: Browsing old krnet lists From: Ross Youngblood Date: Mon, 08 Mar 1999 07:51:54 -0800 X-Message-Number: 5 > Item Subject: cc:Mail Text > Regarding format, Mike Graves makes a good point.

I have all of the email posts to KRnet archived from mid December, 98. I downloaded all of the archives, including the existing KRonline docs from the links provided on KRnet.org web site. I finished reading all of the archives this morning, and have started on the KRonline docs. It has been really interesting to see what was happening with KRnet from the very beginning. Lots of good reading. I really appreciate the effort that has gone into making this all possible. Hopefully I'll be able to contribute something useful before too long. As soon as I get this darn hospital bed out of my computer room, I'll be setting up my drafting table to start making drawings for my KR2 project. My thanks to all who have made this possible, WD -------------------------------------------- Wayne DeLisle Sr. Charlotte, NC mailto:dodger@coincidental.net http://angst.webserve.net/~dodger -------------------------------------------- ---------------------------------------------------------------------- Subject: Re: FAA inspection From: Kr2dream@aol.com Date: Mon, 8 Mar 1999 14:11:48 EST X-Message-Number: 8 Oscar: You make a very valid point. I am a DMIR (manufacturing inspector designee) and when I go to the annual recertification seminars the FAA is strong to emphasize that there are MANY FAAs in that each regional office creates their own interpretation of the regs and therefore each region can have totally different requirements. Such is life when you have an organization without someone to whom they are held individually accountable. The best for all of us is to learn the local requirements and to cooperate to the best of our ability.

The required strength is not a straight line function. It is more of a parabola. If you skip the second taper, you will pick up a pound or two. __________________________________________________ I agree with Don, any weight savings is important in a KR . There is another interpertation of this thread. Some might decide to take all of the material off one side of the spar. This would eliminate the problem of leaving too much weight in the spar and get the dimintions set per the plans. Unfortunately, it would weaken the spar by not keeping the grain of the spar parallel to the axis of the newly cut piece. It is important from an engineering point of view to maintain the spar grain parallel to the centerline of the spar axis. The only way to do this is to cut all tapers on both sides of the spar. The example jig in the plans on page 20 is a little clumbsy to operate because of the blocks that they recomend. I have a suggestion to help you with the jig that I got from Norm while watching the "New Yankee Workshop". If you look at the two long pieces that set the taper angle for the spar, at the apex point where these two pieces come together place a door hinge. At the opposite end place a slotted piece of metal. Get a couple of special screws from the hardware store that have a screw on one end an 1/4"x20 thread on the other end. Put the screw into the end of the long boards and use a wing nut and washer over the slotted metal piece to set the exact angle that the spar taper will be cut at. By making this simple modification to the jig that is shown in the plans it is quick and easy to set the spar taper to exactly what you need in a couple of seconds. This makes the issue of cutting tapers only the time to run it throught the table saw. Since the taper of the spars is at a constant angle the vertical spacers between the spar caps can be cut with the blade of the table saw set at that angle and you get good fit at all glue joints.
