You'll never be able to live with the extra hole, because the rudder's the first thing anyone in the know looks at. Flame on, but it's the truth! (Next is the fiberglass tips, then the overall rivet lines). Prepare yourself now. Order an extra full sheet of .016, .025 and 2'x4' (At least 2'x2') sheets of .032 and .040 from ACS or Wick's. Do it in one shot now, because it'll save you shipping and you WILL NEED TO FABRICATE "OOPS" PARTS!! Fact of life.

You've picked a great company (Zenith) with one of the best lists around to support you. Option 1: The idea of buying someone else's rudder, while not a bad one considering how many are just collecting dust, doesn't do much for your education. If you don't work through these issues on your rudder, you will likely find yourself repeating the same kind of mistakes on your horizontal stabilizer. Use this as a great learning opportunity and invest some time (and money) into your education as a craftsman. Option 2: If there is any way you can attend a Rudder Workshop, I would advise it. You're going to spend a fair amount of money just replacing parts, so why not start from scratch under the watchful eye of the good folks at Zenith. I'm sure you would see your confidence soar. Option 3: If that doesn't work for you, I would encourage you to watch "Metal Working 101 with Rudder Workshop" from www.homebuilthelp.com. It's a lot cheaper than traveling to Mexico, MO or Cloverdale, CA and you can benefit from some excellent instruction in the privacy of your home. Then when the replacement parts arrrive, you'll feel better prepared to tackle the job. Option 4: Build your rudder (or at least the replacement parts) from scratch. You have everything you need on the plans you received, and for a very few dollars you can buy the sheet aluminum and make your own parts. If you decide to go this route (which I have), I would suggest that you watch and re-watch "Scratch Building Basics for Metal Aircraft," also from www.homebuilthelp.com. You might be amazed how easy it is, once the guys from Can-Zac have taken all the mystery out of scratch-building. Whatever your choice, know that you will never regret the time you spend educating yourself and remaking each part until you can be absolutely convinced of its airworthiness. That is time well spent. -------- Larry Winger Tustin, CA 601XL #6493 from scratch Control surfaces and wing spars complete Read this topic online here: http://forums.matronics.com/viewtopic.php?p=115255#115255 ________________________________ Message 18 ____________________________________ Time: 03:55:48 PM PST US From: "Bill Naumuk" Subject: Re: Zenith-List: Re: Noob errors on rudder kit - need help Ron- I second the HH recommendation.

I looked into the rotary about 4 years ago, found one ready to go, tested on the stand for a lot of hours. But the weight was about 225. Must not of had the aluminum end housings. There was a article in Sport Pilot a few months ago on three RVs, one of which had a rotary in it. I remember that the fuel burn was about 15% more than any thing else with the same HP.

What a great group. Sigh, sounds like my best bet is to just start over. The DVDs sound like a good idea too. While I'm quite comfortable with the engineering issues, this is the first time I've ever worked with sheet metal or used a cleco. I have to admit I'm not all that comfortable with the build quality of the rest of rudder either so a new kit is probably in order. I definitely want to have confidence in what I'm building! As far as fabricating parts, I feel like it would just take to long. While I do enjoy this sort of work, and I find the process fascinating, the point is to have a plane to fly. I'm in my 50's and a student pilot - and I absolutely love flying. Another couple of years of build time for fabrication sounds like forever right now. I may invest in some aluminum stock anyway just to see how it goes. So, anybody have a rudder kit laying around they would like to offload :-)?

It will work out to about the same cost as a new rudder kit and take just a hair longer. Fact of life- you're going to have to make some components on your own sooner or later. Might as well get the confidence and satisfaction of doing it from scratch early on. My best advice is to remove your clocks and ignore your checkbook register. By the way- I'm building from a kit, in my 50's, and hope to finish my project while I can still pass a medical. Of course, Sport Pilot is plan B. As far as a plane to fly, rent.

If you have a hole in the wrong place you can often just fill it with a rivet. If your holes do not match up quite perfectly drill them out with a #20 drill bit and install an A5 rivet. Accept the fact that you are going to make mistakes and that in most cases they can be repaired in a very satisfactory manner. If your goal is to make a "perfect" plane you can give it up right now. Feel free to contact me off list if you have other questions.

I was planning on writing out a few tips for those who follow, so here goes. Download and read the new Construction Manual (found in builders area of Zenithair.com under Zodiac XL, Photo Assembly Guide Updates near the top of the list). If you are using an Olfa knife for cutting your webs, be sure to score them plenty of times because of the .040 thickness. Anything less than 20 to 25 times, and I ended up with a ruined web. Edge dressing was a breeze with a Vixen file (http://www.ch601.org/tools/) and 400 grit wet/dry sandpaper. I kept checking it with digital calipers from Harbor Freight to hold close to the 212mm width. Per the Construction Manual (CS #304) this is a critical dimension. Bend your 20mm outboard flange before tapering the opposite end or marking your hole pattern. Use matched-hole drilling wherever possible. Randy Bryant does a good job of describing that at http://www.n344rb.com/ under Wing Spars on his 5/4/2006 entries. Step drilling makes all the difference on the quality of your solid rivet holes. Pre-drill everything to #40 first. Another Randy Bryant tip involves spot-drilling your spar caps. Put them in position under the web and barely drill through the appropriate #40 holes to mark the caps. This makes final drilling super simple (because it is self-centering) and extremely precise. Youll need to set up your drill press either in the middle of your table (http://www.ch601.org/resources/spar_cap/spar_cap_drilling.htm) or along the edge (http://www.mykitlog.com/lwinger) entry for 2/25/2007. This insures straight rivet holes through up to four layers of aluminum without introducing bowing. Dave Clays bending brake is great for making the spar cap angles and miscellaneous smaller parts. http://www.daves601xl.com/Tools/tools.html When bending the angles, make your blank wider than the developed length to give the brake something to grip. I used 100mm. On longer pieces, I even drilled out the material under each bolt hole to grip the entire length without bowing. Use your bending brake to make the hat stiffeners. See my entries for 3/9/2007. Think through your drilling process carefully. I devised a 4-step process that worked perfectly for me (3/17/2007 entry). Step drill your bolt hole for the AN-4-10 bolt, working up to a D bit, followed by a hand reamer. When you are ready to rivet, immobilize all open rivet holes. The AN-470-AD-5 rivet holes can be held together with the black clecoes. The AN-470-AD-6 rivet holes are too big for clecoes, so I went with AN3-10 bolts (using a washer on both sides). This made the stack very rigid for final riveting. Riveting has its own rules. Ill make another cheat sheet on that in the future. Disclaimer: I realize there are a number of ways to make your spars. These are just the ways that worked for me. For more details, you can look at my site (http://mykitlog.com/lwinger) between 2/17/2007 and 5/28/2007. Good luck and feel free to email me off-list if you have follow-up questions. -------- Larry Winger Tustin, CA 601XL #6493 from scratch Control surfaces and wing spars complete Read this topic online here: http://forums.matronics.com/viewtopic.php?p=115319#115319 ________________________________ Message 33 ____________________________________ Time: 10:18:11 PM PST US From: Gary Gower Subject: Re: Zenith-List: ping pong balls, expanding foam, shrinking memory WAS Marcelo Matocq It was a GREAT trip... was Marcelo Matocq: From Argentina to S&F then to OSH with a used Flightstar ultralight with a rebuilt 2 cycle 582 Rotax engine...

I already bought the following components, and really just need a diagram to show how these particluar devices should be wired together: Key Ignition switch (the kid that has L-R-BOTH mag positions) Cessna-style split master switch Standard starter solenoid (provided by Jabiru) Regulator (provided by Jabiru) Everything else I can figure out (and mostly have completed) but this main section of the electrical system has me at a roadblock. There are lots of terminals on the back of these particular devices -- some connections are obvious, others not. I've already read Bingelis' book, I perused Bob Nichols web site, studied the diagrams provided by Zenith & Jabiru. However, I couldn't find anything that uses the exact items above to see how they are all interconnected. I'm not interested in becoming an electrical engineer -- I just want to know how to hook this stuff up! So, before I give up and sell the whole darn project, thought I'd take a stab to see if anyone out there coincidentally used the same components as I am and maybe could share a schematic.
