Stone To: Zenith List Sent: Sunday, July 30, 2006 8:40 PM Subject: Zenith-List: Special tool list members, On the DVD "Building a glass panel" produced by "HomebuiltHELP" I saw a tool that I am very much interested in The tool was one round flat disk that worked like an anvil. The other disc's were round and different sizes with a 90 degree flange that was very sharp. There was a center hole where a large bolt would go in and a nut w/washer on the other end. this would be placed in a sheet of aluminum with a pre drilled hole the size of the bolt and when the nut and washer were tightend it would make a perfact hole to mount an aircraft instrument. This is by far the best system I have ever seen for making instrument holes and I would like to get one. Do any of you have any idea who stocks this tool.

We expect to make the conversion over the upcoming winter. This engine looks much more robust and heavy than our installed Subarus, but the final weight will be similar (due to getting rid of the redrive, cooling system, ...) You're right saying there is not a great deal of info. More guys (probably here as well) use the 6 cylinder engine which is essentially the same construction and a lot could be learned from those people. I read that the o-200 mount does not really fit the engine, unless you don't install the alternator (there is a conflict between the alternator and the mount). For the o-200 cowling, not sure, but I will most probably know that soon (I intend to buy the o-200 cowling). For the engine mount, I'll make one myself and have it welded by a specialist. Last week, I bought an Ivo Prop (Magnum model, in flight adjustable), that I will install on my Subaru installation and then, will be compatible with (or better suited for) the Franklin after changing one plate. I look forward to try this! This being said, I'll certainly keep the list informed as I go through the conversion and flight tests. I do expect an increase in performance and a reduction in maintenance effort.

I'm down to that point......got several sheets of poster paper, which is the same thickness as the .016 skin aluminum, and am about to start cutting the paper for fit. This approach worked well on the wing tips and some other areas; sure saved my rear in that I messed up the paper, not the aluminum, in getting a good fit. Just wondered if any of you guys found any problem areas that are not addressed in the Assembly Manual or on the Drawings. Specifically, does the layout for the root top skin on page 7V9 fit as drawn, or is there a fudge factor required? Now if the temperature would just get below 100 I might be able to survive working in the hangar.

There were many different thoughts went into my decision, not just the fact I didn't want to use an automobile engine. A lot of it came down to value, what I'm getting for my money... I've heard stories of Corvairs getting built in the $2K range, but I've got a feeling, that I'd be spending in the $3500 range to build it like I wanted it, and maybe more, since I was planning on having a custom billet crankshaft made for it... In the back of my mind, I'd always be concerned about the Corvair crankshaft, nitrided or not. With all of that said, I'll go farther and open myself up to flames I'm sure: The engine I bought is ready for overhaul. Everything is there: complete engine, carb, starter, mags, baffling, oil cooler...etc. I have a few friends that are A&P mechanics. I have a few friends that are good machinists... We've all talked and by pooling our resources, we think we can have a fresh O-235 for about $4K...including the cost of the core. Now here's the kicker and what I'll probably get flamed for: It won't be "certified" when we are done. I believe you can have a good, solid crank/case combination, this is what's importants to me, without the word "certified"... This word really don't matter a great deal to me in this application... NOW, if I were installing it on a certified airframe, that would be a different story, but for an experimental airframe, I don't value that so much...

If you plan to use an auto conversion, I'd stick to reputable VW, Subaru or Mazda engine converters with a good track record in aviation. The guy a hanger down from me is putting a supersharged RAM Subaru in his Glasair. Nice looking engine with a nice layout. I have a Rotax 912ULS and love it for the power/weight ratio and reliability. It's not a surprise that some many new SLSA use the Rotax 912/912S. Having said that, I sometimes yern for a real experimental like the rotary engine (Wankel) ... because of the extreemely good power to weight ratio, the much reduced vibrations and the ability to boost intake pressure far beyond a typical piston engine (no overhead valve leak). The closest Wankel match for the 601 or 701 would probably be Rotamax. Downside to the 912S, Subaru and Wankel is need for water cooling. It's just one more factor to deal with ... but minor in my opinion.

The cool factor is large. You wouldn't believe the number of people who are interested when you tell them the engine is converted from a '65 Corvair, and that you built it yourself.

I did a little research ... A urethane primer weighs about 12 lbs per gallon wet and contains about 80% solids (pigments, binders etc) ... so approximately 20% of the primer weight is lost in drying. Dry primer would therefore weigh about 9.5 lbs/gallon. A polyurethane top coat would weigh about 10 lbs per gallon wet and contain about 65% solids. Dry weight would therefore be about 6.5 lbs per gallon for the top coat. A clear coat would be about 8 lbs/gallon with 60% solids, leaving about 5 lbs/gallon dry weight. Assuming that the aircraft has approximately 350 sq feet of surface, and that there would be about 6 coats of paint (two coats primer, two top coats and two clear coats) and assuming that you would be using about 1 gallon per 775 sq feet ... then you would be using a little under 1 gallon of each type of paint (nearly 3 gallons total). All in all, you'd be adding 21 lbs of dry paint weight as opposed to the 30 lbs of wet paint quoted previously. That's 4.5 pounds of dry paint on the tail (as apposed to the 6 lbs quoted before). The total CG affect would be .8 inches rearward instead of the 1 inch quoted before. Not as significant as previously estimated, but still pretty significant on a light plane such as the 601XL.

There were many different thoughts went into my decision, not just the fact I didn't want to use an automobile engine. A lot of it came down to value, what I'm getting for my money... I've heard stories of Corvairs getting built in the $2K range, but I've got a feeling, that I'd be spending in the $3500 range to build it like I wanted it, and maybe more, since I was planning on having a custom billet crankshaft made for it... In the back of my mind, I'd always be concerned about the Corvair crankshaft, nitrided or not. With all of that said, I'll go farther and open myself up to flames I'm sure: The engine I bought is ready for overhaul. Everything is there: complete engine, carb, starter, mags, baffling, oil cooler...etc. I have a few friends that are A&P mechanics. I have a few friends that are good machinists... We've all talked and by pooling our resources, we think we can have a fresh O-235 for about $4K...including the cost of the core. Now here's the kicker and what I'll probably get flamed for: It won't be "certified" when we are done. I believe you can have a good, solid crank/case combination, this is what's importants to me, without the word "certified"... This word really don't matter a great deal to me in this application...

There was a guy who had an O-235 who had built it the same way I'm planning and made it uncertified... He wanted to sell it... I was going to buy it, but another guy beat me out by one day... I was one of 4 people who were in-line to buy this engine too.. SO there are buyers out there... I'll also bet that it would be easier to sell a fresh, good running, uncertified O-235, than it would to sell any auto conversion in the same shape...

There were many different thoughts went into my decision, not just the fact I didn't want to use an automobile engine. A lot of it came down to value, what I'm getting for my money... I've heard stories of Corvairs getting built in the $2K range, but I've got a feeling, that I'd be spending in the $3500 range to build it like I wanted it, and maybe more, since I was planning on having a custom billet crankshaft made for it... In the back of my mind, I'd always be concerned about the Corvair crankshaft, nitrided or not. With all of that said, I'll go farther and open myself up to flames I'm sure: The engine I bought is ready for overhaul. Everything is there: complete engine, carb, starter, mags, baffling, oil cooler...etc. I have a few friends that are A&P mechanics. I have a few friends that are good machinists... We've all talked and by pooling our resources, we think we can have a fresh O-235 for about $4K...including the cost of the core. Now here's the kicker and what I'll probably get flamed for: It won't be "certified" when we are done. I believe you can have a good, solid crank/case combination, this is what's importants to me, without the word "certified"... This word really don't matter a great deal to me in this application... NOW, if I were installing it on a certified airframe, that would be a different story, but for an experimental airframe, I don't value that so much...

The challenge of getting an auto conversion right in the first place is more difficult, but the auto conversion guys are doing us a favor and should be encouraged. Automotive conversions are one reason aircraft engines dont cost more than they do. They have competition. Every auto conversion that is successful provides incentive for the conventional aircraft engine suppliers to compete, if indirectly, against lower prices. I wouldnt drive an air-cooled car and dont find nostalgia for the old air-cooled motorcycle. These are the same reasons that I like the muted sound of a water-cooled conversion. I know youre going to see a lot more of them in the future because of fuel issues. I do like the Corvair and the Jabaru. They are the Cadillac of whats out there right now, but the Subaru is still a great value if you want to work through the basics.

I certainly do see a value for all of us because of those who step out of the mainstream. I will say that one-off, one-time personal conversions are probably not going to help the industry much as compared to reputable rebuilders/distributors who make it their mission to perfect the conversion and retain an institutional knowledge. As you say ... the competition drives the price down and provides a viable alternative for the first-time builder. The one-offs are not going to be much competition to the mainstream and tend simply to drive up accident/incident statistics. Im not bashing Subaru owners or any other alternative engine user. Please, everyone, don't rip me a new one if that's what you think I'm saying. I'm simply reiterating one man's humble, perhaps uninformed opinion, that if you are a first time builder or a first time experimental engine user ... try to stick to alternative engines with good track records modified by reputable rebuilders/converters ... rather than just popping in the Subaru engine from the car you crashed last year. Reminds me of the debate I was in months ago with a guy who wanted to build a 500 air strip in his back yard for his CH701 (trees at each end of the 500 strip). I dunno, maybe I'll get slammed for saying something that seems common sense.

July 28, 2006: Chris Heintz, president of Zenair Ltd. and Chip Erwin, CEO of Czech Aircraft Works, jointly announced today that they have terminated the longstanding license agreement under which the Zenair ZODIAC CH 601 and STOL CH 701 light aircraft designs were produced in the Czech Republic for the European market, effective December 31, 2006. Starting in 2007, the popular all-metal STOL CH 701 and ZODIAC CH 601 Heintz designs will no longer be produced and sold by Czech Aircraft Works. They will continue to be made available across Europe by the Zenair dealer network, as kits coming from Zenith Aircraft Company (Missouri, USA) and as assembled aircraft from Zenair Ltd. Czech Aircraft Works will continue manufacturing the Heintz designs through 2006, and will continue thereafter to provide spare parts and technical support to its existing customers. In the early 90s, Heintz entered into a license agreement with Czech Aircraft Works of Stare Mesto, Czech Republic, to produce and market his STOL CH 701 and ZODIAC CH 601 designs for the European market. The Czech-produced Zodiacs were modified and lightened to meet European rules for "microlight" aircraft. CZAW produced some 750 such machines under this agreement. Czech Aircraft Works has designed and developed its own line of light aircraft, the amphibious Mermaid and the two-seat Parrot and SportCruiser. Heintz (designer and engineer responsible for the entire line of Zenair aircraft) and Erwin both emphasized that the Czech Aircraft Works designs not affiliated with Chris Heintz or Zenair. In the United States, Heintz's designs are manufactured in kit form by Zenith Aircraft Company (in Missouri), and as factory-produced Light-Sport Aircraft (LSA) by Aircraft Manufacturing and Development Co.

I don't think the big engine companies like TCM and whoever makes Lycoming engines really notice when a home builder does a successful auto conversion. I am learning the hard way that these big companies are not oriented toward home builders. We only buy one engine at a time, and generally take more effort than the big companies would find justified by such a small sale. After trying to get even a smidgen of information about the new IO-240 from TCM I am convinced they really are not interested in selling me an engine. They did tell me if I sent them a check they would send me an engine, but they couldn't even supply me with a data sheet on the engine. They do have an 800 number for information, but it seems to be permanently off hook. Other companies like Jabiru and Rotax have distributors or departments that go to the trouble to deal with individual builders. They offer FWF kits and good support for a single engine sale. It is these sorts of companies that might notice a lost sale because of a successful auto conversion. However, these sales groups already have some competition from the big boys and each other. The other side of the whole argument is that people who get personal pleasure and education from converting an auto engine for use in their home built plane are doing just what the whole program is meant to do. They are getting involved in aviation and also learning a lot and having a good time all together. This is worthwhile in my book. I applaud those who go to the trouble to build their own engine. This might come as a surprise to some listers considering some of my previous posts on this subject. My only problem with one particular group of conversion advocates is they seem to have made their choice for misguided reasons.

Mine is serial no 20-0010 a 1995 model. One of the things I noticed about the airplane is a bizarre seat design? and cockpit windows that are heavily crazed. This airplane is on its 3rd or 4th set of windows in only 12 years of life and 1150 hours TT. It spent a lot of time in New Hampshire where it was a flight school trainer. Any Zenair CH2T or CH2000 owners out there willing to suggest alternatives to the LEXAN windows that obviously don't work with this plane very well. I have been around airplanes for 45 years and an owner for 32 and this plane has some of the worst windows I have seen. AMD in Georgia offers a factory rebuilt on the airplane for $20,000 US and factory rebuild on the cockpit area for $6000 US but neither includes paint. I am looking for information on the costs of replacing all of the windows in terms of raw materials and labor? and I am also looking for information on any one who has had the factory cockpit upgrade done? How long did it take? Were you happy with the results? Did Zenair meet their schedule for completion of your airplane? If this is not an appropriate list for CH2000 questions please suggest an alternative web site or organization?

Thankfully, a contractor friend let me use his account number when I had to get the 10/2 I used to run from the main box or I would have had to take out a bank loan!

The "typical" conversion as described by William Wynne provides more power than an 0-200. If anyone wants exact performance numbers all they have to do is go to: www.flycorvair.com. It's all there. While economics is one of the reasons some of us have chosen Corvair, it's not the only reason. I like the fact that unlike most auto conversions, the typical Corvair conversion gets less HP as an aircraft engine than it did as a car engine. Most of the engines used were 110 HP in the car while some were turbo charged and pumping out 180+ HP. The conversion I'm building will put out 100 HP at 2800 RPM. A lot has been said about the lack of corvair reliability, especially as it relates to broken crankshafts, however, this issue was almost unheard of in 40 years of corvair auto conversions until recently. Most of these recent failures were from folks pushing the limits, by building more powerful engines, increasing displacement and other "expirements". My hat is off to them. They are the real expirementers. I'm just building a plane and an engine with proven track records.

I saw the plane at Sun-N-Fun one year. I've lost track of him, but I suspect that his email address is in the archives or that he could be found in the telephone directory for a reference on the Franklin engine.

We expect to make the conversion over the upcoming winter. This engine looks much more robust and heavy than our installed Subarus, but the final weight will be similar (due to getting rid of the redrive, cooling system, ...) You're right saying there is not a great deal of info. More guys (probably here as well) use the 6 cylinder engine which is essentially the same construction and a lot could be learned from those people. I read that the o-200 mount does not really fit the engine, unless you don't install the alternator (there is a conflict between the alternator and the mount). For the o-200 cowling, not sure, but I will most probably know that soon (I intend to buy the o-200 cowling). For the engine mount, I'll make one myself and have it welded by a specialist. Last week, I bought an Ivo Prop (Magnum model, in flight adjustable), that I will install on my Subaru installation and then, will be compatible with (or better suited for) the Franklin after changing one plate. I look forward to try this! This being said, I'll certainly keep the list informed as I go through the conversion and flight tests. I do expect an increase in performance and a reduction in maintenance effort.

When I spoke of performance, I meant to speak about aircraft performance rather than engine performance on a test stand. I don't have enough information to have a real opinion, but I have heard a few comments from real airplane builders that the speed numbers for CH601HDS planes are about 50% higher with Jabiru 3300 installations than with Corvair installations. This might be a reflection of the actual airplanes rather than the engines, but it is all I have to consider. Aircraft performance comes from a combination of actual engine horse power (as measured on a dynamometer) along with propeller selection and weight. I have never heard of a Corvair conversion that could compete with a real aircraft engine like the Jabiru. I am not sure about the Lycoming O-235, but the numbers given on ZAC's web site indicate it gets considerably more cruise speed than the numbers given by list members who have actually spoken about their performance with Corvair installations.
