It really helped me out. I think I'll opt for the Corform plastic cardboard stuff to distribute loads and some lid boxes for the smaller items. It is amazing: you stand all alone in your remote little workshop, scratching your head about a problem no one in the vincinity of 100 miles would even understand. So you switch on your PC and soon a whole bunch of nice guys who've been-there-done-that peek over your shoulder and give you some hints. As I said: amazing! I will try to give my 2Cents back in the future. And Thanks Mat for this forum, the e-mail list was already brilliant but this here makes it even more fast and easy.

From: "Peter Barthold" --> Zenith-List message posted by: "Peter Barthold" Hello Allen, as you see from the other thread I'm nowhere near finished. But not long ago I had the same question as you. Yes it is more complicated to build, yes you may have (solvable) problems like locker door bulging in flight. However, I asked Viktor Strausak, a former military pilot and Swissair Captain. Located in Switzerland, he built the most perfect 601 I've ever seen and flies it all around the continent. He gave me a demo ride at a local fly in. The HDS was still packed with their camping gear. All Lockers stuffed up and with almost full long range tanks we were only few kilos below full gross. With its 80hp Rotax it was certainly not a rocket any more but as agile as a plane can be. Viktor dropped a wing and turned her "on a beer coaster" with no effort. He said, "You need the wing lockers!" And indeed, I would cut down the plane in a strength where it is hard to beat: its hauling capacity. See previous post for numbers. I am not aware of a Rotax 2 seater (other than Heintz design) that has legally more loading capacity. That's why I will build wing lockers. Some day I'll be glad to have them.

I noted he had no before and after comparison figures, as he put on Vortex Generators (VGs) prior to flying his plane. He also gave no TAS figures, only IAS. N601Z is unpainted so I figured she was an excellent candidate for some experimentation. N601Z, without VGs, flies much as Michael described the flight performance of his plane, with VGs. I washed N601Z and re-test flew her to verify lift-off, climb, cruise, low speed handling and stall. I made GS from .025, as per Michael's article and glued them on. Flight test report: Lift-off - no change Climb - no change Cruise - no change Low speed handling - no change Stall speed - no change :-( I sent the following to Zenith: "I need an informed suggestion. Do I start moving the VGs back and forward to see if I get any positive results or is this a waste of time?" Nicolas Hines replied: "I have forwarded you e-mail to Chris..." When I get a reply I will post it here.

I find it very natural to fly with. It is easy to fly with "cross handed" if needed. I believe it would be safer in a crash than having something extra between your legs.

You need to have your aileron in place and shape the wing tip to the aileron. I just adjusted all the measurements based on the amount I needed to merge with the aileron. So (as an example) if you need to move in 5 mm at the rear spar, you would adjust the other measurements accordingly. Then use these new measurements for the other wing. Hope this helps.

A friend that is building a Rans S-6, and that has their standard dual stick told me to try his on for size today. Trying to get my leg around that stick (and not being quite as limber as I was when I was a tad younger), while not impossible, definitely makes me appreciate not having to maneuver around that stick every time I want to get in or out. Also my daughter that flies with me regularly has some physical handicaps that would likely make it a real chore for her to enter or exit the airplane trying to get past the dual stick setup. Something to keep in mind if there should ever be the need to make a fast exit from the aircraft in an emergency situation. I wouldn't trade the center stick for duals in mine for anything. Besides, it is quite comfortable to operate.

Discussion welcome --> Zenith-List message posted by: "Dave" I think you misread his response, the water temp gage is needed, however Rotax uses an installation point on the cylinder head that does not directly contact the water/coolant but reads the temperature of the water jacket. Only the cylinder heads are water cooled on a Rotax engine, not the cylinder sleeves or block. I hope clarification this helps.

Another way I have found to shut down "smoothly" our Rotax 912S is reving the engine to 2,500 or 2,600 (aprox), then at the same time shut the ignition with one hand and pull close the throttle with the other hand. Once mastered the syncro, is a very smooth shut down for this engine. Almost no shaking. Just need to find out a way to start it cold with low initial shaking... Sometimes I get it but most of the times, no. Probably there is no problem at all, everyone says is something normal in the 912 engines, but I personaly dont like that shaking and will like to avoid it if possible. Yes, the engine has the slip clutch. Once more, sorry for changeing the subject. Saludos Gary Gower. Flying from Chapala, Mexico 701 912S. Dave wrote: --> Zenith-List message posted by: "Dave" The bore on my Rotax is 84mm (3.3"). I'm not sure what size the corvair has but I'll bet it's larger. The Rotax has a dual plug system with dual ignitions that are checked just like the Lycomings and other similar aircraft engines. I get a rpm drop when switching one off just like they do. And just like the others my ignition switch grounds out the ignition circuit so a switch failure is more apt to keep the engine running than kill it...but that's for Murphy to figure out. One check I do is when shutting down the engine I let turn off one set 5 seconds before the other. Shut down is smoother and I get a "Mag" check on shutdown too. Dave 601-HD 912ULS -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com]On Behalf Of Brandon The piston area of the lycos is so large that running both spark plugs will produce a much more complete fuel burn, as proven by the RPM drop on mag checks. The same results would likely not be realized in the corvair with such a small diameter piston, even with two spark plugs, so running both ignitions does not help there. --------------------------------- Yahoo!

One of the things I discussed with him was the choice of E-LSA or E-AB airworthiness certificate for my CH601XL. This came up for several reasons, but the main one was the fact that one of my local EAA club members just got an E-LSA certificate for his new Kit-Fox. The only down side to the E-LSA choice seems to be the need for a 16 hour class to get the repairman's certificate needed to sign off on annual inspections. I don't mind this very much since I think the training would probably be valuable anyway. One down side cited by the EAA when I asked them about this was the notion that you can't fly a plane with E-LSA certificate at night or under IFR. It turns out this is just plain wrong. E-LSA planes can be flown under the same conditions (except over densely populated areas until the rule is changed) as E-AB or part 23 certified planes. Of course the special equipment requirements apply for flight under these conditions like nav/strobe lights and instrument checks. The bright side of the E-LSA choice is a shorter phase I flight test period. The guy with the Kit-Fox got only 5 hours. The inspector told me my choice of Jabiru with the new Sensenich prop would probably get me 10 or 15 hours of phase I requirement. Just about any engine/prop we put in a Zodiac would get a 40 hour requirement if certified as E-AB. I completely misunderstood the regs about E-LSA. I thought only a kit from an S-LSA manufacturer that was built to exactly match the S-LSA could get this certificate. It turns out the reg written for the "Ultralight Trainers" is worded so that anything that doesn't meet part 103 can get this certificate and be used for flight training for hire for several years. (Of course, there is no guarantee you can get insurance for that training on a home-built airplane.) Anyone facing the same choice (which should be nearly everyone building a 601 or 701) should talk to their inspector or DAR to get the latest information before finalizing the paper work. Paul XL wings - ________________________________ Message 30 ____________________________________ Time: 09:25:42 PM PST US From: Gary Gower Subject: Re: Zenith-List: Zenith History --> Zenith-List message posted by: Gary Gower In this matter, I think (my point of view only) that this is just a "I supose" thing... I am sure that if one owner of any of the older models needs some advise (about repair and or mantainance) on his airplane. He needs only to ask them (letter, email or phone call to ZAC) and he will recieve an answer or advise. Same with the newer models. Now that we are building the XL, now that the 701 is finished, the construccion tecnic is very similar with the 701. I think that Mr Heintz is a very consistent designer, so the newer models (never seen any "oldies", so I only supose) have their share of legacy from the older ones... Hope I got understood a little, given my english. Saludos Gary Gower. Paul Mulwitz wrote: --> Zenith-List message posted by: Paul Mulwitz Perhaps the most important part of the Zodiac/Zenith history is the Heintz family structure and the way the different members of this family get involved with the aircraft. There are 5 different men involved in this business - all of them members of the Heintz family. Chris is the one who actually designs airplanes. He is now retired or nearly so. His only relationship to the Zenith Aircraft Company in Mexico, MO (as far as I can tell) is that he is the father of the two principals there - Sebastian Heintz the president, and Nicholas Heintz the technical wizard and factory manager. I think the two Heintz boys do a reasonably good job supporting ZAC and its products - especially Nick. I don't know what their involvement might have been in earlier models, but it is unreasonable to expect them to do anything with the models unrelated to ZAC. There are two other brothers of Sebastian and Nick involved in the airplane business in the USA. Michael Heintz is working to set up some sort of operation on the West coast, and there is another (whose name I don't know) involved in AMD in Georgia. Perhaps the doubt expressed by the original lister in this thread is related to misunderstanding that there is a single Heintz and single company that is responsible for all the Heintz designs. There is not.
