Is it conditioned at all? If it is more of a sine wave than a square wave the slow rise and fall times may trigger false signals in E-1's input circuit. But it is true that all the MGL manuals I have looked at show the RPM pickup going directly to the engine. The link below points to a spec sheet for the GT-1 (look at page 57). It says the GT1 has "Fast operating speed - over 100 kHz". http://stevenengineering.com/Tech_Support/PDFs/31SSS.PDF Good luck and Happy New Year. -- Craig -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of NYTerminat@aol.com Subject: Re: Zenith-List: Tach RPM error --> Zenith-List message posted by: NYTerminat@aol.com Craig, The signal for the tach on the 912 is a seperate pickup coil seperate from the ignition system.

Here are some numbers on the building process that prospective builders don't always think of (I didn't). I'm one of those 'average' builders. Before I started my build I didn't know how to read plans, didn't understand how to install a compressed air system, was uninitiated in the arts of proper edge distance (still learning here), and (cripes!) who would have thought building an airplane involved so much filing. To date I've purchased the tail and wings kits, a cost of about $5,000. I've also purchased $550 in replacement parts for those that I've ruined; a defect rate of about 10%. This rate also translates well to the amount of time spent on rework (less the time spent on cursing, moping, and reconsidering this mad mad adventure). Less objectively, if I could give my earlier self advise it would be, "If you only want to fly then buy a completed aircraft". After all, there are lots of used aircraft that may bought for less than a new kit aircraft.

This issue is seemingly simple because the Construction Manual states the "Absolute Minimum edge distance" as 2 x Hole Diameter; great here's a fixed standard. This issue is confusing because the plans sometimes call for rivets to be placed closer to edges than this standard (for example part 7V4-4 on drawing page 7V5 specifies a rivet line (for A5 rivets) 7mm from the top of the part. I get concerned because I calculate the minimum edge distance as 2 x 4mm 8mm. Hmmm, what am I missing? I'm also having difficulty achieving minimum edge distance on the Bent L Angle that is riveted to the side of part 7V4-5 (see page 7V5). How have you experienced 701 builders solved this problem?

I ask because I am told bolts in that location should fit snugly. Here is some text, written by an aviation consultant with respectable credentials (and member of our local EAA chapter) that discusses this: "A loose joint will allow relative motion (wear and fatigue), will allow moisture (corrosion), will cause hardening of the bearing surface (eventual cracking), will transmit loads unevenly to the material it is supposed to hold (stress cracks) and will allow the bolt to cant sideways in a single shear application (cracking under the head of the bolt or thinning a softer material, weakening it)." Complete text here: http://www3.sympatico.ca/fhofmann/art_round_hole.html BTW, the article discusses the black art of drilling round holes (as opposed to those pesky triangular ones).

First, a 1/8" rivet is around 3 mm in diameter. 2 times that is 6 mm. This comes out to 4.5 mm from the edge of the hole to the edge of the metal since edge distance is measured from the center of the rivet hole. An A4 rivet is close to 1/8" and an A5 is just a little bigger. My guess for the minimum A5 edge distance is 6 mm. It gets a little fuzzy when you consider where edge distance applies. It seems that when you are putting rivets into an "Angle" the distance does apply to the open edge of the angle but not to the edge where the bend is. I don't know exactly why that is, but that seems to be the case. Perhaps one of the better trained listers can address this subject for both of us.

Any jig you want that could remain in place while you rotate the wing would cover some of the wing area you want to paint. I spent a lot of mental energy trying to come up with convenient ways to turn a wing over while building it and could not do it without having the wing tip removed. That allowed using the lightening holes as points to attach the handles. That said, you might be able to build a stand that holds the wing from underneath. Perhaps some kind of floating supports like the kind you find on boat trailers would work well. You could lay the wing on the stand to paint one side and turn it over after the paint has dried to do the other side.

It uses sound to calculate RPM. I might serve as a backup to verify the optical and other tachs you are testing. You could install it on your laptop and take it out to the airport with you. I had a geared Continental engine that I tested it on several years ago, and it seemed more accurate than the 45 year old tach in the Cessna.

No! More time consuming? Yes When I decided to build my 601HD I was really scared. The only other plane I "built" (more like assembled) was an X-Air. When I spoke to a friend who built an XL and he told me the only thing he ever built before was a bird house. That gave me tons on confidence. My kit was an unfinished plane and still put in a year to finish it. It could have been sooner but I spent a lot of time on the interior, engine and electronics to "get it right" I'd do it again in a second (and some money! ;) The main thing to remember: dedicate the time to do it and stick to it.

First, I have no experience with quick build kits so I can't say for sure how much easier they are than regular kits. I suspect the focus is mostly on making the build process faster rather than easier. I am sure some of the problems are already solved - particularly those that get major components to fit together properly. Still, I am sure there are plenty of challenges left for the builder. If that weren't true the FAA 51% rule would be violated. Some people start building an airplane kit with the idea it will be similar to one of those Revel (TM) plastic plane kits we all built as kids. This is far from the truth. In the plastic kid's kits all the parts are formed and made to fit together before the box is opened. The kid only has to add glue and place the parts where they fit to complete the basic structure. A little trimming and the model is ready to paint. Another view of the notion of a kit applies to kits like the ones provided by ZAC. In this version of a kit, the kit provider does the leg work to find the correct materials needed for the finished plane. They also prepare some of the raw materials to limit the quantity to that needed for the project rather than the quantity normally sold by the material manufacturer. For example, aluminum sheets are commonly sold in 4 by 12 foot sheets. However you might need a rough cut piece 6 inches by 14 inches for a given airplane part. ZAC would cut the 6 by 14 piece from a large sheet and label it before putting it in the kit. The builder still needs to completely lay out the part, mark and drill whatever holes are needed, deburr the edges and holes, and figure out how to install the part where it is needed. In this kind of kit, the builder is saved the effort of locating numerous suppliers who have stock of the exact material needed. They also save the builder from having to buy a standard quantity of the material when they really need much less. Another service provided by ZAC is to preform some of the parts. They decide which parts and which operations on those parts are too difficult for the builder to perform. The reason might involve how hard it is to do the operation or how specialized the equipment needed for the operation might be. That is all part of the kit design process. So, some of the parts have pilot holes drilled in them and some don't. Some are pre-bent before going into the kit and some are not. ZAC also provides extensive builder support. Some of this is appropriate for plans builders while other support goes to all builders. It often involves interpreting the design and sometimes involves dealing with builder mistakes and how to correct them. All builders, being human, eventually make some mistakes. It may be possible to correct them without replacing the parts or it may be necessary (or desirable) to replace parts. All of that is part of the building process and part of the factory support game. Hopefully this has been enough to make the process more clear. Anyone can eventually build a plane from a Zenith kit. It may be more important that the person is careful (e.g. measure twice, cut once) rather than for the builder to have a lot of experience. There is lots of help available for those operations you don't really understand. I think persistence is the most important quality for a successful builder. The job is big enough that it takes several years to complete. In that kind of job there are going to be many times when a builder will ask himself if it is really worth continuing. This is especially true after he discovers a mistake that requires going back and either fixing the mistake or replacing materials and doing it over again. If you have the kind of determination it takes to complete such a project then I think you should give it a try. If you are the kind of person who tends to give up on something if it is difficult or painful then you might be best advised to consider an easier hobby.

When these posts started showing up a few days ago I was tempted to respond, but decided against it as the posters were merely representing their well-deserved opinions. My concern, though, was that a prospective builder would be dissuaded by these comments. One poster made it sound as though if he, an educated and experienced person, made such mistakes, then ALL builders must be having the same problems. I am purchasing the various kits as I could not afford the entire kit at once, and have completed the rudder, horizontal stab, and one wing (almost) with zero mistakes! That's not to say that today may be the day I skrew up, big time. Admittedly, I work at a slow pace, reading each process many times before I start, and I never work with distractions. When my 4 yr old grandson comes over, I stop. When I read a sentence 3 times and still can't grasp the picture, I stop. If building is what will bring you pleasure, then jump in - the water's fine!

The problem with this senario is that when the fuel goes to 0 my cg is 479 which is aft of the 450 limit. I may get a bigger battery for the firewall. I also expected my WL,WR,WN measurement to be the same as lances' but I came up with a WR WL of 770 and a WN of -535 which was quite a ways off of Lance's measurement.

Most of the edge distance issues relate more to thin materials, that when pulled together by a rivet create a ripple or stress wave to occur. Too close to the edge and you eventually will see cracks from each rivet to the edge. Probably would take a long time. Same goes for too close a pitch. Eventually you see a crack running from rivet to rivet because of the stress wave that circles one rivet affecting the circle of stress at the next. When you get too close to the edge, the circle is upset by a broken wave and eventually the material relaxes or breaks. The edge distance issue probably has a margin for safety, but that would depend on the size rivet and the thickness of material as well as the kind of material you're working with. 6061 aluminum is probably the most forgiving of these, where 2024 would not.

There are three others on the West coast that have one, but I have not seen responses on the list. I received my QB kit just before Christmas, and have had little time to do anything with it due to the holidays, kids out of school, bad weather (still rearranging the garage, as I was not sure the fuselage would fit where I planned It did) and some other family stuff. I have not actually seen up close what the standard kit looks like when it arrives, but from the pictures Ive seen, my kit has a LOT of the work done. I have been told that about 9500 of the 10,000 holes have been drilled, so that eliminates a lot of the room for error. A bunch of the holes that are left to drill are in the rudder kit, which I have already done. (I even drilled two holes in the wrong place, but a quick e-mail to Nicholas H. let me know it was not a fatal error). For those of you with the standard kit, my kit arrived with the fuselage essentially ready to put on the gear. All drilled, corrosion proofed, riveted etc. I mean the thing is pretty much done to the point that the engine could be hung on the firewall, as the studs for the mount are in place. The leather interior (came with it) is ready to go in. I can already sit in it and make engine noise, but I wont until its on the gear. Think that would save any time? ;) Most, though not all of the remaining pieces have holes drilled in them, so if they dont line up, youre putting the part in wrong and you need to check again. If it fits, its probably right, and ready for a quick brush of Core-tec, cleco, and rivet. The wings were put together on a jig, drilled, clecod, and taken apart again for shipping, so they are much more finished than the regular kit as well. The above being true, there is still a whole lot of work left. I will need to corrosion proof the wing parts and put them together. Lots of wiring, plumbing, avionics (what I can afford) engine installation etc. to do. It also appears that many of the parts have been zinc chromate coated on the mating surfaces too, so Im not sure how much corrosion proofing I will have to do. I know that some feel the QB kit is not a real kit plane building experience. There are plans builders that think the standard kit is not a real building experience either. Im 40, and have two kids. I want to build the plane in my lifetime without having my kids hate me or my wife divorce me, so I went with the QB kit. Hey, the difference for the QB is a LOT cheaper than a divorce. I figure however long it takes me to build the plane, I will be flying YEARS ahead of where I would with the standard kit. Yes, you can buy a plane to fly right away for less money. It will however, be MUCH more expensive to fly and maintain. Ive wanted to build since I was about three, and have been collecting kit aviation magazines since I was very young. All forms of building, and aircraft rental or ownership for that matter, have trade offs. The QB kit seemed the best choice for me. By the way, the quality of the parts and building appears to be excellent. The rivet lines and spacing are very uniform. Most of the standard builders would hate me if they saw the QB kit and realized the time it would save. That being said, it did cost more. Regards, Allen Ricks Beaverton (Portland) OR.

However, at 5'10 and 235lbs there is more then enough room in the 601XL that I can even wear a large hat. The 701 typically has more headroom and with the new bubble doors from Zenith the cabin width is a full 44" the same as the 601XL. Fitting you is not a problem in either plane even with a passenger of the same size. You should consider what you really want to do with your plane. The 701 is a special breed and is a STOL performer. IF the drastic STOL performance of a 701 is unnecessary then go with the 601XL. Both planes offer an incredible view and the high wing over the low wing in the view aspect seems negligible. Personal preference and mission are the lists you should be drawing up to help in your decision now. Check out http://www.frappr.com/zenith601 and http://www.frappr.com/zenith701 Look for builders and owners in your area and plan for a visit, I have yet to ever meet a Zenith owner who would not let me have a seat in there plane.

Besides, the extremely good view and performance the XL provides. If you want to go places, the 601 is more of a destination plane. The 701 is world class STOL but considerably slower, nearer to something like owning a helicopter. Their both great planes, but are really different breeds. You should definitively examine your flying experience and the kind of places you want to go for the one that will do the best job for you.

Less would be even better. Then there's engine, avionics, electrical, and paint work to do... My research before building showed that most people (that kept track) took about 1000 hours give or take for the standard build. I'm guessing there is more slop than people admit when they leave the shop for a while and stare at the drawings for a couple of days before proceeding. Oh well, at least most of the interior is done... My goal is a year, but safety and family first, so it takes as long as it takes. As a comparison, here's a link to Van's QB kit picture.

Yes, I have researched the Zenith website and compared the measurements but am looking for some real world input. I'm a 6 footer and weigh about 220. The 601XL seems like it would be a roomier and more comfortable cabin just from looking at pictures even though the dimensions are not substantially different than the 701. For my type of flying either model would suit me fine as far as performance etc. but am concerned about he fit. Thanks in advance for the input.

Less would be even better. Then there's engine, avionics, electrical, and paint work to do... My research before building showed that most people (that kept track) took about 1000 hours give or take for the standard build. I'm guessing there is more slop than people admit when they leave the shop for a while and stare at the drawings for a couple of days before proceeding. Oh well, at least most of the interior is done... My goal is a year, but safety and family first, so it takes as long as it takes. As a comparison, here's a link to Van's QB kit picture. Note that the fusalage AND the wings are pretty well done. Van estimates there is about 1000 hours left to do. http://www.vansaircraft.com/images/rv-7_quickbuild_lg.jpg Versus the Zenith QB page: http://www.zenithair.com/zodiac/xl/xl-qbk.html Many people don't understand that the small stuff, not the big stuff is what takes the time.

I'm leaning towards the Jabiru. It seems to be the best fit. Really expensive. The Rotax is expensive to buy AND expensive to maintain. The Lycoming O-235 is expensive to buy and heavy. I want something very reliable that has a well sorted install kit so the auto conversion are out for me. I know there is a contengency of Corvair proponents, but the engine is a little on the heavy side, and if I were going heavy I'd lean towards a rebuilt O-235 instead. The Jabiru is installed in the factory demo plane, and at 800+ hours it has more total time than any single install of most of the auto engines have. The Jabiru is finally getting enough of an install base that I think it will be around for a while. That being said, I will wait until the very last minute to make a choice on engine and avionics, as things seem to be changing at a rapid pace. In avionics the Dynon with the big screen and the engine guages in it looks pretty good. Wonder what we'll get a year from now?

You actually said it much better than I would have. I originally went to the Zenith factory to look at the 601XL and didn't like the way that you had to climb into the 601. That's just me. They showed me the 701 and my initial reaction was it was too small (much like a toy), then I saw the 801 and took a test fight in it. Nick took my wife and I up for a flight and I immediately fell in love with the size and handling. I scheduled the rudder workshop for the 801 in Oct 94. My wife and I built the rudder and was ecstatic at how easy it was( we all know how good the rudder draings are compared to the rest of the kit). I went home and had to decide whether to order the kit or not. I wanted to be able to fly from my own property and decided to clear land and see where I could get the longest strip in line with the prevailing westerly wind. I was able to get a 1300 ft grass strip with power lines on one side and trees on the other. I still wasn't completely convinced that the 801 was my best choice for my 1st build. I looked again at the info pack that Zenith sent me home with and looked hard at the 701 as my 1st build. I felt that the 801 was perfect for me (was used to flying with 4 seats in Pipers and Cessnas) but it was so slow and I felt that I would be disappointed with that. Looking at the 701 at roughly 1/2 the price I felt that I would loose the 2 extra seats and almost get the same speed. I could always build another plane at some later date if I chose to. I was comfortable with the decision and called Shirley in the end of November to place my order. I was ready to build a plane and Shirley told me that there was a 10-12 week lead time for the kit, but would try to get the tail out sooner. Received my first crate at the end of January and started building a CH-701 on 2/8/05. My rudder, elevator and stabilizer was done by 2/20/05 and I had to wait for the rest of the kit. March 4th the Yellow freight driver dropped off the big crate with the rest of the plane. I am now built, painted and almost ready for my DAR inspection scheduled for 1/11/05. The building has been a hoot and loved the experience. All the guy's on the list have been great and very informative. THANK YOU EVERYONE! While most of the info I got off the list has been thru following other peoples questions and problems, When I have had a specific question I have quickly gotten an answer. I have not had to have too many calls to Zenith (a few in the beginning to Nick and then a couple to Roger). They have always been quick to answer my questions. The drawings took a while to get used to reading and the info is not always where you would expect to find it, but for the most part the info is there if you look hard enough. The photo guide has been a big help but as some have mentioned don't rely on them and ALWAYS verify things with the plans. I have made some parts over because I didn't look ahead to the next couple of steps but that's all part of the building experience. I have a lot of respect for the scratch builders out there. I wouldn't have the patience to fabricate every part. I found what adds time to the building process is when you add your own stuff. I chose to install Larry's wing tip access doors, additional fuselage oil canning stiffeners, as well as the additional rear fuselage door ( a must in my opinon). I installed an electric flap operator and taxi, landing lights in the leading edge of the slats (that was fun). I also picked up some century 3 auto pilot servos from E-bay. I have them installed for roll and pitch and control them from my stick grip. ( no actual autopilot head yet) I call it my "poor mans autopilot". It should allow me to point the plane in the direction that I want it to go and be able to leave the stick alone. To those who are contemplating their 1st build I highly recommend a Zenith kit. I found the Rudder workshop was the best way to start to immerse yourself into aircraft building. Zenith has been great as well as Danny and Zaneta from Skyshops. I bought the firewall forward package from them. They have been very helpful with my questions as the Czechworks drawings also leave a lot to be desired. They have updated their parts but not the drawings. I didn't plan on writing this novel but I felt that those lurking out ther would appreciate the info.

However, at 5'10 and 235lbs there is more then enough room in the 601XL that I can even wear a large hat. The 701 typically has more headroom and with the new bubble doors from Zenith the cabin width is a full 44" the same as the 601XL. Fitting you is not a problem in either plane even with a passenger of the same size. You should consider what you really want to do with your plane. The 701 is a special breed and is a STOL performer. IF the drastic STOL performance of a 701 is unnecessary then go with the 601XL. Both planes offer an incredible view and the high wing over the low wing in the view aspect seems negligible.

I think it is telling that Zenith switched from the Rotax to the Jabiru. And going with a direct-drive engine can only lead to less trouble than choosing an engine with a re-drive. And the XL FWF kit for it is getting better and better. That being said I'm going the Corvair route. Heck, I've *gone* the Corvair route - I shipped my parts and myself to Florida and helped build my engine at William Wynne's hanger and test run it. If I had unlimited funds I don't know what I would choose. But having bought my "kit" 80% complete from another builder I see the engine and control panel as the two areas were I get to innovate (or over-design). As you say you don't have to make a decision for a while but do remember that different motor mounts use different studs on the firewall. Anyway keep an eye on the Corvair world as you build. Right now you can get complete rebuilt engines for $6000. And motor mounts, nose bowls, exhaust and intake manifolds are all available for the XL. Yes, they all cost but the difference between the Corvair and Jabiru 3300 is still going to be $10,000. We need to get a 601XL/3300 next to a 601XL/Corvair to compare weight and performance. -- Craig -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of Allen Ricks Subject: RE: Zenith-List: quick build 601 XL (long) --> Zenith-List message posted by: "Allen Ricks" --> Craig, Not sure yet.

The wing then stands almost, but not quite, nose up. You do have to get under the wing to get to the aft spar and be either tall or use a small step to get to the L.E. I painted my airplane in separate pieces in a 10x20 closed end car tent I picked up at Costco for about $150 U.S. I used a fan with filter to pump in filtered air and to keep the tent pressurized. I used a HVLP spray gun with a separate 2 Qt. pressure can with separate hoses going to the spray head so I could paint up for the bottom fuselage and the aft spar. I suspended other parts from the tent ceiling for painting.The paint I used was Dupont Nason Ful-thane 2k Urethane auto paint with its associated primer. Poly is the best, but that stuff can kill you if you do not use a full fresh air respirator.Tony Graziano 601XL; N493TG--> Zenith-List message posted by: "Al Young" Anyone designed a jig, stand, or whatever that can be used to hold the XL wing for painting?
