The 3 day workshop was conducted by Eric Tucker who works for Kodiak (which is the distributor for Rotax in N.A.) Boy, was this great! Eric has been repairing/supporting this engine from the beginning and really knows his stuff. We had a 912 torn down to every single part on the workbench. And then put it all back together! While none of us in attendance (about 15 students) would ever completely overhaul a 912 (tools, fixtures, and the experience to do it right must be on hand!) it was still and incredibly valuable experience to know how this thing is put together, and what some of the common failures are caused by. Also, we got a history lesson about Rotax and some background on their manufacturing. After finishing the 3 days, you realize that the engine is relatively simple, and become a heck of a lot less afraid of it! I know the class is 'expensive' ($450), but in the scheme of things, it is a great investment and you cant really put a price tag on getting that kind of knowledge! One (maybe obvious) detail that I would like to pass along to all that own this engine is that the HEAVY MAINTENANCE manual along with the Illustrated PARTS manual is ONLINE and downloadable/printable from their website http://www.kodiakbs.com These are the latest versions as I noticed that the one I had from my engine was way outta date. Also, the LINE Maintenance, Installation, and Operator manuals are there, too. These manuals contain so much valuable info.... Also, of course, the service bulletins. Got the scoop on the oil, coolant and fuel types to be used as far as the factory is concerned. Finally now understand why a lot of the Loctite numbers used in the Rotax manuals are darn hard to find around here... they are European versions! Did you know that the 912 series is designed for a 1800 TBO, with a block life design of 3600 hours ? Yes, I know the official TBO is 1200. Also, interesting discussions between the 912 and the 'S' version... more than meets the eye there! Many of you already know this too: the certified versions (F, etc) are the SAME engines we use as UL uncertified and they all get tested at the factory. There are different options for these, of course, but they make no distinction in manufacturing. The extra several GRAND $$$ for certified is the paper trail to track all the parts... etc. I'm sure that's money well spent ;) Now I still love my 503, (Firestar) and would like to attend the parallel course on 2 cycle repair, but that would be another $450 and another day. My 701 project is using a used 912, and I still shudder at the price of that thing (even used!) It seems that these ridiculous prices for parts on the 912 all boil down to limited production numbers.... same ol story. Of course, you cant leave Lucedale, MS (now there's a big town!) without traveling the Florida panhandle... camped at St Joe Island, St George... etc. Paradise down there..... now its back to the Green Bay, Wi weather... burrrr... If you get the chance to go to one of these workshops, IMHO you will not be dissapointed... we made some good friends with the other students... as everyone in attendance was a 912 owner with something interesting attached to it!

I just bought a 66 engine with all the right numbers according to William. It costs $400 which is a little steep, but at least I knew what I was getting and Rob is very willing to work with me for any additional parts I need. I have a rebuilt 0235 that has sit in my basement for 10 years, and I planed to use it, but after researching extensively the corvair option, I decided to rebuild the Corvair and use it. I've already disassemble the engine, and it is a very easy engine to work on. I kinda like the idea that if my engine needs any maintenance, I built it and know how to fix it.

Look at the drawing above (3-aileron skin) and you will see two measurements (295mm and 45mm). I laid the entire aileron by measuring back 45mm. Don't. Use the 295mm measurement. 295 + 45=340. My top skin measures 348mm. That difference of 8 mm will screw up all of the darn top rivet lines. Things worked out much nicer once I understood this. Would have meant new skins if I had predrilled the 20mm flange with my original layout. The way it is I have 10mm spacing on the first rivets now instead of 15. Also get all of the aileron info from the builders page before you start. The instructions from the web site are easier to understand than from the manual.(yes they are different). This was a tuff one!

I would like to make new ones "as per drawing" of 3/16 with 3/16 doublers. The major problem is how do you cut this material when you don't have a power hack saw or band saw.

Make sure you leave lots of hints for your wife, girlfriend, kids, parents or ?? I usually get my point across if I leave the Sunday Sears circular opened up on the kitchen table with things that I need (want) circled. Or you could borrow a Saws All from someone. If you can't find a Saws All, then maybe you can rent one. Check the phone book for places that rent tools. Be prepared to do lots of filing afterwards. Considering all the effort involved it, might be better off to just find a machine shop that has the capability of sheering the metal. You might also have them bend it while you are there.

I did it by hand which was a real pain. Nobody says you have to do it all at once though. I didn't rivet my entire center wing section at once. I did it in several sessions (over 5 hours total time). For the L's that need to be cut down for the gear slides, I used a router. Just shaved it down a little at a time. It worked great. -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com]On Behalf Of alex trent Subject: Zenith-List: cutting alum bar --> Zenith-List message posted by: alex trent My 601 wheel forks are built of 1/4" 6061 t6 flat stock.

Thought I was all set and ready to start building.Now 2 weeks into the project I get to the trailing edge soft rivets of the elevator.The only mention in the plans is for AD470-A3-3 in trailing edge at pitch 40 and only mention in the photo manual is "Note: The trailing edge will only be drilled to number 40 for AD470-A-3-3 soft rivets" No mention of any special tool to set them or anything.No mention in Zenith's tool list either or I would have bought one from them along with the other tools.Also, I see a few pages ahead that I will need to stop work on the plane and build a "elevator horn cable holes positioning template" out of .090 aluminum which I don't have and will have to go hunting for where I can buy some aluminum around here. It's just kind of aggravating to stop work on the plane and build tools or templates.Seems it would be a good idea and could bring in a little more income for Zenith if they would offer to sell all these things along with the other tools they sell.Seems that would make it easier and faster to build the plane and would be "keeping it simple". Nothing against Zenith. They are a great bunch of guys and have good product support and a great product.

Even of 3mm plywood can be used, all the templates (even the curved box to build the 701 slats) are very simple to build and are only a few. There are other airplane projects that are really complicated to build the "jigs" and templates... you are lucky to chose a Zenith to build, dont desparate, you will love to build it. Saludos Gary Gower 701 912S Guadalajara, Mexico. PS. Working on the carboard templates for the front cabin sides (betwen the cabin and the firewall) and the seats. We also built carboard templates for the wing tips, saved the skins from trashing. Results were on the "almost perfect" side. --- Larry Bohannon wrote: > --> Zenith-List message posted by: "Larry Bohannon" > > > ---- Chris has done so well to keep it simple----- I > think some of you folks, are building without getting > the plans etc from Zenair/ Zenith---- Chris explains > so much of what some of you folks ask of this site to > explain-- "fred" do no archive > > I just picked up my complete kit at the factory 2 weeks ago which > included the latest plans and photo manual.I also bought from Zenith > all the tools they recommend.
