I am 75 years old and still fly and build a lot! I built an Avid Aerobat when I was 72. Had a Jabiru 2200 and was a real kick to fly once I got accustomed to the quickness of the response of the controls. My first snap roll with it was by accident. on I really enjoyed aerobatics until I would make myself feel queezy which did not take long. I have a 601HD now that had a Revmaster when I bought it.

At every take-off I was getting an oscillation in the yaw axis, a few seconds after liftoff, for anywhwere from 2 to 5 seconds, which went away if a) I continued climb normally, b) I dropped from 5450 rpm (max) to 5200 or lower. It is felt in the whole airframe, and the cowl looked like it was visibly displacing a half inch as the aircraft "wobbled" in yaw at approximately 3 or 4 cycles per sec. Airspeed is accelerating between 50 and 60 mph at this time. The oscillation is mild, more annoying than concerning. It could not be stopped by pitching up or down slightly, or changing rudder position slightly. No perceptible vibration is felt in the pedals. My rudder cable tension seems possibly slightly on the high side, and I also tried pressing on both pedals during climb, with no change. After adding another pair of dzus fittings at the cowling at the bottom of the firewall, verifying blade pitch and minimum vibration, without any change, it occurred to me that the main gear might be out of balance, and the wheels are spinning down from a 40+mph rpm during this time. Although I don't feel any out-of-roundness or vibration from the gear during the takeoff run, I tried pressing the brakes immediately after liftoff. I made four takeoffs today pressing the brakes after liftoff, and got none of the oscillation, which has been very consistent prior to today. So either the wheels and tires spinning down were the culprit, or I am wrong about my rudder tension, and by braking I'm adding more rudder cable tension (through slop and flexure of the nose-wheel steering hardware) than I did before when trying this by pushing only on the pedals (no brakes). I'll try more with pedal pressure without brakes again, too, to see if I can figure out what's happening. But at least it's under control for now.

However, if you run a likelihood/consequence matrix, it could be seen that the likelihood of a catastrophic failure is very slim, somewhere in the four-decimal-points or more. The statistical probability reaches way out there. If you wanted to halve the probability, you could run two completely parallel electrical systems (wouldn't really add that much more weight). It's somewhat analagous to the hypothetical, "You will absolutely die if an elephant falls out of a 747 flying overhead, crashes through your entire house and lands on you at the instant you step out of your basement bomb shelter." I spent a few days with a Master's in the safety field, and one of the first things we learned back in the old days is that safety is the intelligent application of acceptable risks, not the removal or avoidance of all possible risks. Personally, I like WW's setup. Paul Rodriguez 601XL/Corvair. DO NOT ARCHIVE ----- Original Message ----- From: Paul Mulwitz To: zenith-list@matronics.com Sent: Thursday, July 06, 2006 1:32 PM Subject: RE: Zenith-List: Re: Dynon on Corvair engine It is not clear to me whether Mr. Wynne's dual coil ignition system increases the reliability of the Corvair engine or reduces it. Since the "Dual" parts are not isolated from each other (they are connected at the spark plugs and the battery/generator/voltage regulator) it is possible that failures of any of the additional components could bring down the whole engine. It is clear that the additional components naturally lead to more individual component failures since there are more components. I don't know how many of the component failure modes have been analyzed with regard to one failure causing another part to not work properly. Without this analysis it is not possible to know whether the increased complexity leads to improvement or deterioration of the engine reliability. In any event, failure of the battery, generator, voltage regulator, or any of the related wiring and connectors could lead to an instant engine failure. This is not supposed to happen in true aircraft engines because the dual isolated magneto system doesn't rely on battery power to keep the engine running. That leads me to believe the Corvair conversion, like all auto conversions, is more likely to experience a complete in-flight power failure than a purpose built aircraft engine. Paul XL Fuselage That is correct. It uses a dual ignition distributor with dual coils and single spark plugs. http://www.flycorvaircom/distributor.html It's all a matter of risk management and identifying an expectable level of risk. Everything you do in life is a risk. Going to work this morning in these hills with crazy drivers crossing the center line is definitely a risk. But it was a risk I was willing to take to have the view out my back window. To me, the view from my Corvair powered Zodiac will be worth the calculated risk. - ________________________________ Message 12 ____________________________________ Time: 09:25:45 AM PST US From: "Gary Boothe" Subject: RE: Zenith-List: Sheet aluminum racks Bill, No, but I just had an epiphany yesterday as I pulled out my rolled up aluminum for the 3rd time in two weeks.

I painted the first of the two after flying it a while. It had a thin coan of Chromate while flying it before taking it out of service to paint it. Had to "Strip" the Chromate off before painting. This was the most work on that plane. The second plane I painted is the one I'm flying now. I painted it before ever flying it. It was easier doing it that way. The drawback is the problem of touch up when you have to disturb the nice new paint job for corrections. I've had to do that too. With all that said, I think if I've just built a kit plane to specs, I'd paint it before flying it. Just my oppinion!

It is not as easy as it sounds! If this is done outside the wing, the bellcrank must be removed from its bracket. I suppose it would be easier to reinstall the bellcrank than to try to do the swaging inside the wing, which means reattaching the control rod to the aileron, also through the access hole. While it is possible, I just found it much easier to do with the wing open.

I've been at this since April and only have the small parts nearly done. I'd probably still have done it this way because that's the way I work, but if you can manage to get a coat of paint on it before the fact, you'll save a lot of time.

The outfit that made the part became unreliable and ZAC changed to, what is in essence, a simple aluminum tip rib. Since the kit didn't come with the hinge brackets, the tail light, nor the fairing sheet, I expected that a "real" tip would come with the other parts. Wrong! My tip didn't look finished, so I "dressed it up" a little with some body putty, just enough to fill in between the skin and the radius of the rib flange. If I had it to do over, I would place the rib so that the edge of the skin was at the beginning of that radius, not flush with the top of the rib.

Everything is performance standard and technically, the requirement would be a waste of your time. Worse, if you decided to paint your aircraft with any paint that doesn't like Zinc Chromate, you'd have a mess to contend with if the rivets were part of the surfaces you need to put a finish to. If the materials are so different that they would work against each other, it might be necessary to consider the effects of corrosion, but there aren't any materials specified in the Zenith plans that would do this to you.

If he was up at cruising altitude getting performance data, then maybe he had just finished the engine. Having built many engines and being ASE certified, the one thing that I have always done, is measure the tolerance's of all components, including shaft play from the distributor. As far as the WW conversion goes, Corvair stock distributors had one bearing in them when they came out of the factory, as did many automotive factory distributors. I have seen 2 distributors fail, out of thousands. Both of these were with well over 100,000 miles on the distributor. WW has cut this even further by installing a second bearing in the distributor shaft. He states he has done this for safety and stability of the shaft. I think a distributor failure is very few and far between and WW has lowered the failure rate even further by adding the second bearing. When I built my first WW Corvair engine, I wired the dual points in complete separate systems, including a backup battery that was wired for just the essentials to make a safe POWERED landing. This system works well and can be tested separately when doing a run up. I have no reservations about WW's ignition system. I will fly anywhere with this engine. My first engine had a nitrated crank and has been inspected after 200 hrs. There was no cracks and it was returned to service. ________________________________ Message 39 ____________________________________ Time: 04:16:20 PM PST US From: Subject: Re: Re: Zenith-List: Flap mounting --> Zenith-List message posted by: --> Zenith-List message posted by: "Edward Moody II" I drilled and rivetted the flap hinge when I was rivetting the bottom rear skin.

I did the same thing but when I put the wing on the fuselage, I wasn't happy with the distance between the edge of the flap and the side skin of the fuselage. I ended up buying another hinge, and used half of it to replace the half that fits to the wing, and after setting the flap where I wanted it ( no binding) I re-drilled thru the original holes in the wing attachment points. It worked out fine, just extra work.

I have applied a first coat of zinc chromate to some parts with a sponge brush. In some spots, I get an ugly effect when applying the second coat. It happens almost immediately. All parts where previously scrubbed with scotch brite (color to remain unidentified), and then swiped with a clean rag. I always wear gloves while working. Cheaper than H2O2 and band-aids.

All kidding aside, it is not a glider and probably gets about 5 or 6 to one. Not published anywhere but I asked the question once myself. Here is the thing. You have hundreds more places to put her down than you would an aircraft with a better glide ratio. And when you touch down you will also be going much slower than you would be in a good glider. just my 2 cents David --- Chris In Madison wrote: > --> Zenith-List message posted by: "Chris In > Madison" > > Hi all, > > I haven't been able to find any number on this > during my exhaustive searches and wondered if anyone > has performed any tests that would provide any > numbers to this regard. > > I seem to recall reading in one or two places the > the 801 sinks pretty quickly with no power.

"Brick" is pretty much what I figured. But you're right about the possible landing spots for that one, though. Seems like just about anywhere will do. I took my first flight in one with a local EAA flyer last week, and it looks like it does all kinds of interesting things. Much appreciated :-) Best regards, Chris -------- Chris Owens Waunakee, WI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=46001#46001 ________________________________ Message 50 ____________________________________ Time: 08:40:31 PM PST US From: Carlos Sa Subject: RE : RE: Zenith-List: Primer / paint question --> Zenith-List message posted by: Carlos Sa Drying time was at least 48h...

No paint (except the cowl), no upholstery, no wheel pants. I do get the 'when are you going to paint it?' and 'someday you'll install wheel pants, right?' comments. But, I'm flying and that's what matters to me. Yeah, the plane shows my personality. I'd rather fly than paint, and I like the bare metal - that's the primary reason. Painted planes look good too - but different. If you plan to paint it, do it before you fly. You won't want to take the time after the first flight. It goes without saying that this is my opinion - and what do I know???
