Subject: Canopy Hook Impact
"However, I haven't seen any mention of the impact of the canopy on cabin room. In particular, do the hooks on the side opening option cut down on the width at the shoulders?" I have not noticed any reduction in cabin room as a result of the hooks. Once I have closed the canopy and inserted the retention sliders I don't notice the canopy hooks until I do the takeoff check list. When two are in the cockpit with a combined weight on the North side of 400# we are still surprised at how much room there is. In short, the side opening option has no impact on width at the shoulders or anywhere else. Stan ________________________________________________________________________________

Subject: Battery powered 701 !!!!
Date: Jun 25, 2002
Here's a story with a plea to scientists for understanding: I am working on my wing tanks for the 701... I assembled the fuel sender unit as prescribed and tested it out of the tank with its guage and 12 volts. All is well and the float was adjusted for the tank depth. Cut the hole in the tank and installed the sender. I now proceed to fill the tank with WATER to test for leaks and confirm that the guage reads from empty to full. Everything looks great as I fill... about the first gallon doesnt move the needle (OK), then the needle on the guage slowly creeps up as I fill the tank. When I put gallon 9 of water in the tank, the guage drops to half and remains there even with all 10 gals in the tank (an honest 10 gallon tank, BTW). I cant understand why the very last gallons would cause a failure in the indicated level... but AHA, the last gallons actually cover the rheostat of the sender unit. SO, I figure the water is shorting the rheostat and giving false indications. BUT, I place my OHm meter on the sender unit and find, that with the tank full, the resistance is s l o w l y creeping up from about 30 ohms to 100 over a minute of time!! I scratch my head (picturing that plastic ball somehow not floating properly) and call VDO. Big mistake. They are convinced I have not calibrated/installed/ or otherwise assembled the unit properly. They make it CLEAR that WATER will not affect the reading. Thank them and hang up I now regress to my childhood days of playing with electrolytic capacitors. Im a ham operator from WAY back and this what you did when tearing apart radios and screwing around! When you put an ohmeter on a capacitor, it will charge up slowly and the resistance will increase as it charges. So.... I switch to VOLTAGE reading on the meter and another AHA....I am getting a solid .16 volts generating from the sending unit!! Free voltage as the tank sits there full of water. I have a BATTERY! and no wonder the fuel guage reads wrong when the water gets to the full level! Now, I need help understanding why a ten gallon aluminum tank full of water is steadily generating .16 volts???? I know my water isnt great (from a well) but what are the key ingredients here?? And what about the rheostat helps this situation?? Moral of the story.... dont trust the manufacturer support for help (e.g. water is NOT OK for testing) and I can not beleive I am the first one to run into this problem.... doesnt everyone use water to test their tanks and fuel senders??? Please feel free to tell me this was not a good idea.... I am here to learn.. I hope someone some day doesnt waste an afternoon like I did and can benefit from this story. Do I have the beginnings of an electric car/plane?? no fuel, just a tank of well water?? PLease explain how this batery thing is working!

Congratulations on creating your perpetual motion machine! Seriously, though, if I recall correctly an ohm meter applies voltage to the thing it's measuring. By applying a known voltage and measuring the current through the resistor, it can use ohm's law to figure out the resistance, where more current = less resistance. A volt meter has high internal resistance. You connect it across something that's experiencing a voltage drop. A small amount of current makes its way through the internal resistance of the meter (hopefully much smaller than the current going through the source of the voltage drop), and by measuring that current the meter can tell you how big the voltage drop is. So, what happens when you put an ohm meter across a circuit with a Great Big Capacitor and a resistor in series? The G.B.C. starts off discharged and looks like a wire to the meter, so you start measuring the resistor's true resistance. But an ohm meter applies voltage, so you're slowly charging up the capacitor and the meter shows increasing resistance. Now you've got the G.B.C. all charged up and you put a volt meter across it. The G.B.C. tries to discharge through the volt meter, but the volt meter has high internal resistance, so it takes a while. Net result: I'm guessing you charged the G.B.C. to 0.16 volts and it'll probably take a while to discharge through the volt meter, so it looks like you're creating energy for nothing. As for why the sudden nosedive in indicated fuel, unfortunately I can't help you there - don't know enough about the sender or the gague to know why that would happen.

Subject: OAT - where to put?
Date: Jun 26, 2002
Date: 26 June 2002 Hi Michel I located my OAT probe immediately behind the area of the port side wing gear leg and under the rear fairing. Reasoning: Absolutely no exposure to direct Or indirect sunlight influence. The turbulent airpattern should avoid wind-chill effects, but....the fairings used fore and aft of the gear leg housing will limit serious airflow over the probe anyway and yet allow a reasonable rate of air-change to permit good response times for temp variation occurrences. (I could put some air-bleed holes in if reqd.) NB. My probe is secured with rubber rings sandwiched on either side of the underside wing skin in order to more accurately respond to AIR temp change rather than the underside wing skin temp to which it is affixed. (The rubber being the thermal insulation medium) Hope this helps.

I think that any probes mounted under the fuselage is a great idea. That way it gets them out of direct sunlight. But, If placed in the airstream of the exhaust by accident you will get a high reading. I might have a belly cooler mounted on my 801 to cool the V-8 Ford so I am debating where to put my probe.

Subject: Which prop
Date: Jun 26, 2002
Recently I sent a msg on this subject, and due to some queries I should clarify what I've said about the advantages of air-adjustable props and specifically the Arplast. Although the Arplast has gained me speed, climb and flexibility, I must advise users or people considering using the Arplast PV50 on the Rotax 912 the it is not without some problems. I have had two in- flight failures with the pitch adjustment motor. The first was after 35 hours and the motor was replaced under warranty. The second failure was after 12 hours of use and Arplast refused to consider it a warranty failure. It cost me $350.00 CDN to replace it. Mike Fothergill has had one failure of the pitch adjustment also, while in flight. Barry Hailey had a failure of one of the blades causing loss of pitch control on one blade during take-off. He was able to abort take-off successfully. I thought the list should be aware of these facts.

Subject: Which Prop?
Date: Jun 26, 2002
I can offer some information on this subject. We have had excellent results from the Czech-made Sport Prop. Czech Aircraft Works has been supplying them as the standard propeller for our Rotax Firewall-forward package for both the CH601 and the CH701. The propeller we recommend is the Sportprop 3-blade, 1700R, ground-adjustable carbon propeller. The cost is $585.00. A nice matching composite spinner is also available for $99.00. Many of the aircraft on our web site are sporting these props. The propeller that was referred to by the Spanish pilot is made by the same company now. It was Kremen Propellers. They recently merged with Sportprop, and now the new company is called Woodcomp. The 3-blade electric in-flight adjustable propeller does have excellent performance. And it is now available with a constant-speed option. The cost of this prop with spinner is $2,950, plus considerable crating and freight expense. And it is also a bit heavy at around 12kg. Sportprop (now Woodcomp) also offers a 2-blade mechanically in-flight adjustable propeller. We did ship one to Leo Corbalis, and he appears to be quite happy from his last e-mail on this list. However, it is not readily available in the USA. Based on our European success with the Sportprops, and our increased business with quick-build Zenair kits in the USA we have negotiated the USA distribution rights for these propellers. We now have a nice inventory of new propellers and spinners at our USA importer in Florida - Sky Shop. The propellers are easily sent by UPS. Please note we will stock plenty of the 1700R ground adjustable carbon props for Zenair, and 3-4 of the other most popular sizes and models. Woodcomp offers dozens of models so if someone wants something special, we can ship from the Czech Republic with the next container to Florida. We can also bring propellers to Oshkosh for anyone wanting to pick up a prop at the show. We do not have any plans to import the 2-blade in-flight adjustable propeller. We think there could be a service problem down the road as they need to be returned to the factory for major service. Danny at Sky Shop has been to the Woodcomp factory for training twice now and is fully qualified to maintain the 3-blade electric in-flight adjustable propeller. However, these propellers will be special-order as well. As they probably will not be legal on the new Sportplanes, we do not plan to keep stock in Florida. But we can easily add a prop to our next container... We are willing to send a prop to the fellow who started this thread. If he likes it then he can buy it, if not, send it back. I am confident of the performance.

Subject: Battery powered 701 !!!!
The charged G.B.C. (great big capacitor) is probably the culprit on the voltage generation issue. That discussion seems sounds. The only thing I'd say different is that an Ohm meter puts a known current through the object and reads the resultant voltage to determine resistance. But, the result is the same... The reason "distilled water" is used in batteries, is that pure H2O is a better insulator than a conductor. Put impurities in the water, and BOOM, you have a better conductor... Well water would almost certainly be a better conductor. I assume that by now you have confirmed that when the water level is below the sender (and the sender is dry) the readings are correct (enough). Therefore, deductively, the water must be shorting out the sender some how. Fuel should not short the sender, as fuel is generally a poor conductor. However, I would not want exposed electrical circuits anywhere near my fuel. NO MATTER WHAT the manufacturer might say. A blown voltage regulator may lead to higher voltage, which may lead to sparks. Vented fuel tanks, nearly empty with a litle bit of fuel sloshing around, and sparks just can't be a good combination. I'd seal off the sender somehow. Test it with a temporary seal using a trash bag or something. If that works, then come up with a good fuel resistant seal. You might "pot" the whole underside with some compound. I'd suggest silicone, but I'm sure there are those that would freak out... Dave 701 ________________________________________________________________________________

Being lazy I do it the easy way. 1. open the caliper valve and pump out all the old juice. 2. Take the screw out of the valve body (on the pedal). 3 get a plastic bottle, fill it with mil. 5606 and connect to the caliper valve, wrap an old tee shirt around the valve body. 4. squeeze the bottle until the cockpit is full of brake fluid or a friend yells STOP! 5. close the caliper valve, put the filler screw back, wipe up the mess, now disconnect the caliper cannection and you are all bleeded! On a similar note, when you change the oil in your 912, after everything done and wipe up, stick a piece of fuel hose 1/2 inch O.D. up the 12mm. reservoir vent line. Hook up a bypass switch to the starter solenoid ( so the ignition stays OFF) blow as hard as you can into the hose to get the oil to rise up and flow out of the reservoir to the engine. Now you can start cranking the engine and you will get oil pressure in a few seconds, without starting the engine.

Subject: Engine for 601XL
From: Michael R Fortunato <wizard-24(at)juno.com>
OK, I'm at the point where I need to make an engine decision for my XL. I have it narrowed down between two possible engines: The Jabiru 3300, or the Honda CAM 125. Costs are about the same. The Honda performs a bit better, but is a bit heavier and requires a redrive. So, I'd like advice on the following three questions, which should enable me to (finally) make up my mind: 1. The Honda is of course water cooled, and the Jabiru is air cooled. What I'm concerned about is what happens if I blow a radiator hose while flying...or what if the thermostat sticks...or the water pump goes? I only know that of all the problems I've had with cars over the years, cooling system failure has been a relatively common one. Will air cooling be enough to keep the plane flying if I go with the Honda? The benefits of water cooling are probably to avoid the effects of thermal shock, but I'm wondering if that is enough of a benefit to offset another element that can go wrong. 2. The Honda is fuel injected -- the Jabiru is not. I'm not sure why everything isn't fuel injected these days, but is that issue worth worrying about? 3. Does the redrive itself contribute to the increased possibility of failure? Or are they relatively maintenance free? Thanks in advance for the help.

Subject: Re: Battery powered 701 !!!!
Hi all, I think I remember a little from when I got my Physics degree that may apply here. The tank is aluminum. The water, since it is not ultra pure, is an electrolyte, that is, a liquid that conducts electricity. The rheostat in the sending unit is probably nichrome or another definitely non aluminum metal. So you have different metals with different potentials. I forget the exact term, but will look it up if I do not see it posted here soon. Any way, this is how a lot of batteries work. Ions from one metal are dissolving into the water and migrating under the resulting electric field and depositing on the other metal. Ions carry charge, so you get a voltage and a little current. This is probably more familiar in the use of zinc compounds to percent corrosion of the metal in the aluminum airplane, or in the attachment of "zincs" to metal boats and motors, especially those used in salt water. The zinc is more likely to lose ions than the aluminum, so it is sacrificed to save the aluminum. This is noticeable in a zinc on an outboard motor used in salt water. The zinc gets smaller over time. You can do the same thing by putting a zinc wire and a copper wire into a lemon, or other fruit or vegetable. The acid fruit works better because the electrolyte is more conductive. I suppose this is as clear as mud, but I tried. All for now.

Mike, Not to throw a monkey wrench into the gears.....after all you did say that you have narrowed your choices down to these two engines of about 120hp.......BUT !! (pausing for dramatic effect...) Have you looked into the possibility of the Corvair conversion?? This is what's going in my XL, and it's truly the most bang for your buck, I believe. Mine has all the whistles and bells, 3.2 liters, cheap, six cylinder smoothness, cheap, direct drive, cheap, air cooled simplicity, cheap and easy to build (cheaply!!) Even with all the aforementioned "toots and clangs" such as roller rockers, blueprinting and balancing, altitude compensating carb, custom prop extension, etc........I've got less than $5,000 invested and everything is new or "as new to factory specs". Tough to beat !! This engine will weight less fire wall forward than the Lycoming 0-235 and be more powerful as well. ( IMHO ). I can offer up some links to excellent web sites if anyones interested. While I'm throwing my 2 cents around, I'll comment on your questions by the number.. > > 1.

Okay, water cooling is great, works very reliably as long as you keep the wet stuff inside were it belongs......lot's of designs with water cooled engines flying successfully, including my own RANS S-12 with it's 65 hp Rotax........ But, air cooled is what you want in most cases, it's lighter, air is available at 100% of the places you might have to land ;-) and unless you plan to do a lot of rapid descents from the upper flight levels "thermal shock" just isn't a realistic concern.. > 2. The Honda is fuel injected -- the Jabiru is not. I'm not > sure why > everything isn't fuel injected these days, but is that issue worth > worrying about? Real fuel injection systems are heavy and expensive and provide no magic for your application.......great for our cars.....thank God we have them, but they don't offer anything very exceptional for us, at least not when you weight it against the issues of complexity and weight...........a common Stromberg carb will do nicely if you feel you absolutely must manually control the mixture settings.......but the Jabiru won't offer that and neither will a computer activated Honda auto system, so for my money an Edelbrock Qwiksilver II altitude compensating throttle body is a steal at around $200 and you can get one (or repair parts should they be needed) at almost any Harley-Davidson shop on the planet. > 3. Does the re drive itself contribute to the increased possibility of > failure? Or are they relatively maintenance free? Well, any "additional" system just adds to the list of things that can fail.....but the cog belt style re drives have a solid reputation in general, they are simple and durable if well designed. If you are choosing an engine that requires higher than normal rpm's to generate it's rated power you don't really have a choice, so the discussion is two fold.....do you want an engine that will be spending it's cruise-flight-life at 5,000 rpm wearing out in half the time of a direct drive unit?? I know you can balance the cost of the Honda overhaul (pretty low I'd guess?) against that eventuality.......but toss in the added cost of the re drive, and the extra weight (way out in front!!) and the picture may not appeal to you any more. Of course there are no BAD choices here, you probably know how much time and money you have to experiment with, and that may play as much in you plans as anything else. I encourage all builders to follow their dreams and share their experiences. I only tried to entice you with the Corvair info because I believe it's the best kept secret in experimental light aircraft. > > Thanks in advance for the help. > > Mike Fortunato > 601XL > You're welcome !!!!!

Michael, What an opportunity! Go with the CAM 125! It's really well engineered. The liquid cooled engine is so much better to fly with than an air cooled one. Liquid cooled engines are inherently quieter, burn less gas, have no shock cooling, burn less oil, and they have a parts network in America that is better than any engine from Australia. I've going with a Stratus Drive Subaru, but would consider a Honda engine if to do over. I've got an 89 800cc Honda Pacific Coast and a 91 Honda Civic (same CAM engine), both liquid cooled and each have run trouble free for all this time! The distance between overhaul and valve adjustment for the liquid cooled engines is non-issue for Subaru or the Honda compared to Jabaru, 0-200s?

I don't know about the VDO gauge in particular, but it sounds like it operates just like the WesTach does. Please be aware: 1) You didn't say if you disconnected the meter when you made your voltage measurement. If not, unhook the gauge from the meter and THEN measure.

I scratch 2) If I recall correctly, these meters use a wheatstone bridge for measuring the resistance of the sensor element and have an internal capacitor to dampen the meter movement. Wheatstone bridges have a "null" that represents the meter peak (full) and will "fall" on either side of the null. You could have a merely un-calibrated meter, or if it's like the Westach, there's an internal diode that may have failed. The damping capacitor is the charging capacitance you are measuring. > my head (picturing that plastic ball somehow not floating properly) and > call VDO. Big mistake.

Best to "tune" it with a NON-magnetic type of screwdriver so-as not to affect the meter movement.

Dude! check the back of the meter. This isn't the twilight zone you're in....just some very elegant old genius technology that uses an analog series-parallel comparator (the Wheatstone bridge). They do this because all fuel sensors vary in their final resistance when they come off the assembly line and due to conditions in the tank. With the bridge, you can adjust the meter to match the sensor. If you need more help, a ham friend is a good way to go, but be careful who you seek for your "prophet of electronics". You really need a Yoda to help you. You might be able to fix it yourself by just adjusting the meter. If it won't adjust, call back VDO and talk to their Yoda and find out if there's a clamping diode (a zener) inside. If so, it may have failed and they need to replace the unit for you. Please echo back what you find to the list and check me: I'm not afraid to be wrong. Good luck! May the (electromotive) force be with you!

Ken, If there was a prize to win... you'd be the winner! I researched galvanic cells (batteries) and came to the very same conclusions you did about the mysterious gas tank battery. The mising piece of information for your conclusion is the electrolyte: my water passes through a water softener at home (which uses salt to clean the resin bead every few days) so there is a measurable amount of salt in the water I used. In fact my water softener manual actually provides the number of milligrams of sodium per gallon for people who might drink the water. For the benefit of those who are not following me: The fuel guage is a voltmeter that reads the voltage drop provided by the fuel sender ( a variable resistor using winds of copper or nichrome). As the plastic ball floats up and down, the resistance changes and thus the fuel guage (voltmeter) indicates this change in resistance. As soon as I filled the tank to the very top, the fuel sender was covered with the electrolyte (salt water) and a galvanic reaction occurs as Ken described. Instead of being a variable resistor, the fuel sender is now sending voltage to the guage, disrupting the normal reading. Moral of the story: dont use water to test these things! I was trying to test for leaks AND guage calibration at the same time. In science class you couldnt get an experiment like this to work.... and then it comes to haunt you like this! Nature is full of surprises and wonders. The internet is full of neat information: I now have a copy of the galvanic chart hanging on my wall.

Jabiru 3300 was built to achieve simplicity, which is the biggest warranty they can offer you. "Air cooled? that's not a problem, in Australia there are desserts too" - that's what they said to me in a Jabiru Forum, you just have to take care of making a good flow channel over the cilinders. No drive means no friction, therefore nothing to brake/maintain. Besides low cost, you get high liability. I chose a 912 ULS which is not a bad engine, but I'm thinking seriusly to change to a 3300 in the future. Yago Osset Spain 601 HD almost finished. www.osset.com/yago Mike, Not to throw a monkey wrench into the gears.....after all you did say that you have narrowed your choices down to these two engines of about 120hp.......BUT !! (pausing for dramatic effect...) Have you looked into the possibility of the Corvair conversion?? This is what's going in my XL, and it's truly the most bang for your buck, I believe. Mine has all the whistles and bells, 3.2 liters, cheap, six cylinder smoothness, cheap, direct drive, cheap, air cooled simplicity, cheap and easy to build (cheaply!!) Even with all the aforementioned "toots and clangs" such as roller rockers, blueprinting and balancing, altitude compensating carb, custom prop extension, etc........I've got less than $5,000 invested and everything is new or "as new to factory specs". Tough to beat !! This engine will weight less fire wall forward than the Lycoming 0-235 and be more powerful as well. ( IMHO ). I can offer up some links to excellent web sites if anyones interested. While I'm throwing my 2 cents around, I'll comment on your questions by the number.. > > 1.

Okay, water cooling is great, works very reliably as long as you keep the wet stuff inside were it belongs......lot's of designs with water cooled engines flying successfully, including my own RANS S-12 with it's 65 hp Rotax........ But, air cooled is what you want in most cases, it's lighter, air is available at 100% of the places you might have to land ;-) and unless you plan to do a lot of rapid descents from the upper flight levels "thermal shock" just isn't a realistic concern.. > 2. The Honda is fuel injected -- the Jabiru is not. I'm not > sure why > everything isn't fuel injected these days, but is that issue worth > worrying about? Real fuel injection systems are heavy and expensive and provide no magic for your application.......great for our cars.....thank God we have them, but they don't offer anything very exceptional for us, at least not when you weight it against the issues of complexity and weight...........a common Stromberg carb will do nicely if you feel you absolutely must manually control the mixture settings.......but the Jabiru won't offer that and neither will a computer activated Honda auto system, so for my money an Edelbrock Qwiksilver II altitude compensating throttle body is a steal at around $200 and you can get one (or repair parts should they be needed) at almost any Harley-Davidson shop on the planet. > 3. Does the re drive itself contribute to the increased possibility of > failure? Or are they relatively maintenance free? Well, any "additional" system just adds to the list of things that can fail.....but the cog belt style re drives have a solid reputation in general, they are simple and durable if well designed. If you are choosing an engine that requires higher than normal rpm's to generate it's rated power you don't really have a choice, so the discussion is two fold.....do you want an engine that will be spending it's cruise-flight-life at 5,000 rpm wearing out in half the time of a direct drive unit?? I know you can balance the cost of the Honda overhaul (pretty low I'd guess?) against that eventuality.......but toss in the added cost of the re drive, and the extra weight (way out in front!!) and the picture may not appeal to you any more. Of course there are no BAD choices here, you probably know how much time and money you have to experiment with, and that may play as much in you plans as anything else. I encourage all builders to follow their dreams and share their experiences.

---------- Original Message ---------------------------------- Honda Vs Jabiru I have the CAM 100 but not flying yet. Water cooled. Not really a serious threat for instantaneous engine failure. IF water pump fails it is gradually manifest by a leak. Hose failure rare with good pre flight. Use silicone racing hoses for water system. Probably relatively easier to install a radiator in good location than to make baffles, cowling vents flaps etc to get good air cooling. I believe the jabiru comes with cooling ducts though. Air cooled engines noisier, have to be have larger tolerances and are cooled with oil and fuel expenditures as well. Need to be overhauled sooner and vibrate more. In favor of the Honda: proven reliability some 15 million engines made in past few years. No pushrods simple proven design. High RPM not a problem. S. Honda understood this when introduced the engine in 1940's power based on piston feet travelled works out to about the same. See kit planes article on this few mo's ago. Fuel injection. Simple reliable no carb icing or altitude probs. attitude probs. Ignition system bullet-proof. Power development Jabiru necessisarily develops it's peak power at higher than 2500 RPM because smaller displacement direct drive -- translates to smaller less efficient prop. REdrives not really a problem Honds redrive is massive bearings at both ends of drive shaft, no eccentric crank loads, No problems.

These are the two most important issues with the Jabiru. How are the actual cooling airflows and airspeeds working out for those on this list flying the 3300? Getting good air to the rear cylinders in a 3-cylinder bank has historically always been a challenge. The small prop diameters have historically posed performance penalties on VW engines using similar RPM ranges - so you want some hard numbers here and not just engineering estimates. imho. The CAM125s biggest 'issue' is the weight, but it is in the same range as the Lycoming etc. I believe. The VTEC delivers excellent torque to the prop through a wide range of rpms (a good candidate for constant speed prop?)... the dual electronic ignition is an excellent, dependable unit... I'm surprised that the original posting said both engines were equal on price. When I chose the CAM100, one reason was that it was significantly less expensive than the Jabiru 2200.

Phil, I don't know how the skin is bent on the trailing edge of your elevator. The rear 20 mm on mine has the top of the skin bent up as per the plans and the bottom skin just follows it along. Thus the last 20 mm of the elevator is bent up about 20 degrees (this bend is to give the trailing edge some stiffness). Thus, effectively, the elevator has some built-in down trim. Too bad that the top and bottom skins were not bent about 10 degrees each so they would mate without the trailing edge being up or down. ZAC had this problem on their 701 and bent the trailing edge of the elevator to a neutral position. Mine is per the plans and I expect to start off this way, as trying to bend the riveted trailing edge might be hard to do and get it straight. As far as performance, the added drag is negligible. I would try my suggestion and see what happens. Also, I am going to try different flaperon adjustments to find the optimal zero flap position. Hey, this is what experimental is all about.

That was me, and indeed the prices are very close to being the same, when you factor everything in (engine, cowling, redrive, prop, etc). That's part of what makes this decision so tough! :) Anyway, looks like I'm leaning towards the Jabiru. For a simpleton builder like me, ease of installation is a HUGE issue, and the Jab would seem to be much easier. After objectively analyzing the numbers made available to me by both manufacturers (and other listers), the CAM would seem to be the better performer, even with the added weight (you won't get 125 hp out of the Jab unless you run it full throttle, I'm told). But, there's also much more to go wrong with the additional components of the CAM, so I'm not sure this little extra performance (assuming it exists in the real world) is worth it. Nonetheless, as others have mentioned, a builder could probably use either powerplant and be perfectly happy. I just wish they weren't so darned expensive!

Finally! After a couple of setbacks (overly wet, rainy spring weather,/ garage breakin and loss of wing attachment hardware not to mention handtools, etc...) I've got everything back together and I was up for three circuits and a short tour this morning. No one can ever accuse the 601HDS of being a docile aircraft! This thing growls! I usually open the throttle slowly to avoid gravel damage on my local strip, and I hardly get the second barrel of the carb 'kicked in' and I'm almost airborne. I'm sure this thing will out-accelerate the Airbus 319 -- at least for the first 60 mph! ;-) My landings are still 'carrier arrivals'... I think I stop flaring because the nose gets so high and I'm losing sight of the horizon... then boom - it hits and sticks.... anyways, I need to spend more time playing with it in slow flight and flight on the edge of the stall, out in the practice area, to get more familiar with the attitude at min. speeds. I still over-estimate the glide (if you can call it that! ha ha), and need to add power on final often. I'm still practicing mostly power off landings from circuit altitude, to force myself to know the glide characteristics. I don't like long shallow approaches with single engine aircraft, especially if there are houses below and few landing spots.... old training from my ab initio training days, I guess.

Subject: Ten thousand and still going...
From: Grant Corriveau <grantC(at)total.net>
I lifted the flight envelope to 10,000 feet this morning (10,400 on the gps). The average climb from 2,500 asl was somewhere in the vicinity of 300 fpm... At 10,000 the climb rate was still about 200 fpm... I was getting cold at 8 degres C (no heater) and shorts (hey - it was 25 at the ground). When I levelled off, the cruise speed settled down around 90 mph ias (about 107 tas using gps), so I know there was more climb left still... I was getting about 5200 rpm at takeoff power near sea-level, the climb at full throttle (of course) produced almost 5000 rpm most of the way up, and an honest 5,000 in cruise. I guess part of the reason for this consistent rpm is the Warp Drive prop's tapered ends that are supposed to provide some sort of 'twisting' effect (If I understand the theory correctly), and the CAM100s excellent torque applied through the 2.4-1 reduction drive. In the dive/descent back down to warmer air, I took advantage of the water cooling. I pulled on the carb heat, throttled back to about 3,000 rpm, and dove the speed up to 140 mph with about a 20 to 25 degree nose-down attitude. FUN! Almost worth the climb-time... I peaked out the speed to 150 (carefully) - new top speed so far. Everthing remained attached to the aircraft as it should! ;-). The aircraft is sensitive to lateral imbalances. I've increased the size of my aileron trim tab and it helps a little, but burning the fuel down on the left a couple of gallons helped a lot more. Once I get the wing lockers cut in, I may have to be methodical about the lateral balance by moving stuff from locker to locker. -- Grant Corriveau Montreal Zodiac 601hds/CAM100 C-GHTF www.theWingStayedON.ca ________________________________________________________________________________

Subject: MAC trim control grip - no like it!
From: Grant Corriveau <grantC(at)total.net>
Does anyone else not like the MAC stick grip with the imbedded trim buttons? This seems to be a poplular unit, and the motor, etc. is certainly reliable enough and seems to work well. BUT - the grip with the five buttons (4 for trim plus Push to talk) is a nuisance. To be specific, here are my beefs: 1/ in the first place, having to solder together those teeny little #26 wires was a job I didn't want. Why didn't they tell me it was a 'do-it-yourself'? Or maybe I didn't notice the fine print? 2/ the trim buttons themselves are too small and the tactile feel is such that it's hard to find the correct button without accidentally trimming something - usually something I didn't want. 3/ the trim buttons don't provid much feed back as to when contact is being made. 4/ the trim buttons are way too easy to accidentally hit! I've had my leg run my aileron trim full over, and sometimes while resting my hand on the stick, or using the outboard hand temporarily, I've accidentally sent the elevator trim into 'pilot-induced-runaway' mode. I thought I was having a serious control problem of some sort the first time it happened! I plan to move the aileron trim off the stick onto a panel switch somewhere as this is not a switch that gets used much. Long term I hope to sell the thing and replace it with some sort of 2-switch model with a nice tactile 'pickle' or 'top=hat' swicth for the pitch trim, and a trigger for the PTT... but for now I must remember to keep my knee clear of the trim switch... -- Grant Corriveau Montreal Zodiac 601hds/CAM100 C-GHTF www.theWingStayedON.ca p.s. don't let anyone else read this as I may want them to sell them this unit later!

For all you detectives out there, here's one for you... Last year my VSI seemed to work perfectly fine. This year it is acting strange: 1/ It reads zero on the ground 2/ as soon as I'm airborne it under-reads by about 300 fpm in the climb... 3/ in cruise, when flying level, it indicates minus 300 fpm... 4/ after landing, it shows zero again. 5/ the asi and altimeter seem to be working fine I need to check it after a long-term level off (i.e. is it a leak in the static line that eventually equalizes?), and during descent... The fact that it is zero on the ground, seems to tell me that the problem is not just gauge calibration, but something in the lines. I've connected them the same as last year, but I'd better check the hoses I've used for cuts or holes....? Other ideas?

My two cents worth.. The pins were too long anyway on both parts, so I made up a wad of resin-soaked glasscloth and positioned the metal parts through the holes drilled in the lower cowl. Once the resin had set I drilled and installed rivets to give a permanent hold. This all solved the problem of the two parts not fitting well.

I can picture the wad of resined cloth holding the steel flange and being crammed into the nose area, and getting glassed in, but what did you drill through to apply rivets?

I suggest that the gauge case or glass seal is leaking to the sealed capsull ie the case bypassing the metering orifice, when you are flying the cabin pressure is probably less than the static port pressure so if you are flying level it shows you decending, on the ground the pressures will be equal & so the gauge will read zero Clive Richards ----- Original Message ----- From: "Grant Corriveau" <grantC(at)total.net> Subject: Zenith-List: VSI problem > > For all you detectives out there, here's one for you... > > Last year my VSI seemed to work perfectly fine.

These have to be the two favorites because they are localized to the VSI instrument itself -- my ASI and Altimeter are normal. I consider the 400 feet difference between the indicated altitude and the gps 'true' altitude at 10,000 ft. to be quite normal. I haven't run the numbers into my 'plastic wheel', but I should do that for interest). I'm leaning towards the 'seal the glass' idea as it seems to better explain the instrument's behaviour. The 'proof' I think, will be to cruise for a longer term at say, 1,000 feet and see if the VSI eventually zeros. If it does, then the problem is a blockage in the VSI inlet/tube somewhere. If it is continuously 300 feet negative, then it is due to leaking at the instrument, sensing the lower relative cabin pressure vs. the static port on the wing... Does that make sense? I'll check it out and let you know.

Subject: Time to do the HOOK mod!
From: Grant Corriveau <grantC(at)total.net>
I was just levelling off and accelerating, and noticed my T-shirt sleeve tickling against my left (i.e. outboard) upper arm. I've felt this before (my canopy isn't well-sealed yet), but this time when I glanced over my shoulder, I was shocked to see daylight under my canopy edge directly AT the left rear canopy hook, and the hook was partially 'unhooked'! OOPS! I immediately reduced the power and eased the speed back to 80 mph and made sure the aircraft was fairly stable. Then I looked again to see if it would be safe to try to close this, or might I just cause the forward hook to let go? I checked the front hook and safety pin, and it looked nice and secure. The rear hook was just partially displaced inward, so I gripped the inside handle and squeezed down, while pushing the hook outward, setting it back into the fully-latched position. It seemed to be happy to stay there, so I assumed that maybe I hadn't checked it carefully enough before takeoff. I maintained 80 mph, and eased on home, frequently checking for any further signs of movement in the hook. After landing, everything seemed normal, so I more or less wrote it off to 'not properly closed' before takeoff. Today, however, I discovered that this is not the case. After takeoff, I checked the hook, and again, I found the hook had worked its way toward partially unlatching! Same drill - easy power reduction and slow down (i.e. no sudden, lift-inducing pull-ups) to 80-90 mph. Push outward on the hook and squeeze the canopy rim down. It worked again, and I returned to a normal landing. The problem is definitely a combination of speed/lift on the rear canopy, and the fact that my hook doesn't reach far enough outward over the tube, and doesn't have any 'over-centering' function. Actually when I built the thing, I was surprised to see the shape of the hooks. These original units depend entirely upon the spring-loaded/tourque force to keep them in place. With some stretching outward/upward by the canopy frame against the white nylon 'saddle', and maybe a less-than-perfect amount of overhang on the flat-bottomed hook, this corner was just waiting for an opportunity to let go. Anyway - I bought a piece of steel on the way home from the airport and will install the new hook mods that Chris Heinz has posted on the web site. I stronly recommend to everyone that you take some sort of remedial action to improve the original hook designs. Minimally, install a lock-pin in each of the 4 hooks.

Grant, Remember the old trick, that if the static line gets plugged and there is not an alternate static source, you can break out the glass in the VSI. The altimeter will have a lag due to the orifice in the VSI and the VSI will read backwards, but you at least have a static source.

Subject: Help with the HDS Outboard rear skin
Date: Jul 02, 2002
OK, this is what I get for finally working on my plane! I think I've goofed. I just sent a note into Zenith about the following, but was wondering if the real world experts had any ideas. I only checked this about 800 times before I drilled!! Here's the note I sent to Zenith: ============= I'm placing the rear skin on the right outboard wing. After lining it up, clamping it down AND drilling out the ribs, I noticed a problem with the alignment. With the skin clecoed to the ribs, it aligns with the Rear Zee until you get to S9. From there to the outboard edge of the Rear Z, the Z now shows. It goes from flush to about 7mm exposed where the Z ends. The skin also extends over the Spar towards the leading edge by about 7mm at this location. I can "twist" the Z at the tip so that it fits correctly to the skin edge, but this appears to be putting a strain on the tip rib, bending the flange slightly. It also leaves the skin over the spar. This twist causes the Z to run at a 90 degree angle from the table as well at the tip. Alternatively, I can remove the clecos from S9, move the skin to line it up, but this misaligns the holes I just drilled in S9. It also put a slight pucker in the skin, that seems to work out in securing down the skin, but I can't be sure at this point. Is either of these a viable fix, or do you have another idea? Obviously, I'm hoping I haven't completely ruined the wing skeleton ============== Any ideas from the list?

Subject: HDS skin problem
Hi Mitch, I found a similar problem on mine, and, after investigating it further, found that it was caused by a backward bend in the main spar near the tip. I hadn't drilled any holes yet - just clamps at that point. I was able to straighten the spar using clamps and carpenter's squares and some jury-rigged jigging using blocks drilled into the table top. Once the top and bottom skins were drilled and riveted, all came out straight. Since you have drilled your holes, you have a more "advanced" problem, but certainly fixable. First, check the spar for a warp or bend, then, once straightened, check to see how far off the holes are. Is it possible to replace A4 with A5 holes to cover the offset? If not, how about adding new holes between those already drilled, and then re-drilling the old skin holes into new spots in the ribs and zee (but don't put the holes too close - especially be careful with the spar in this regard). New "in-between" rivets won't win you any prizes for cosmetics, but will only be noticed by experts, and will only add strength - if not too closely set. If these techniques are not possible, another possibility is to put in new metal using "L-angles" under the rib flanges and rear zee (L's under the zee will need to be bent to accommodate the zee's obtuse or acute angle). Rivet one flange of the L to the rib side, with the other directly underneath the rib flange, making undrilled metal for new drill holes (because of the crimps, this may require several short L's between the crimps). Now, just drill through the re- inforced rib flange and ignore the old rib flange holes. If these approaches are not to your liking, it may be necessary to get new ribs and possibly the zee, but certainly not a new spar. It won't help to get new skins, since the pre-drilled holes will be in the same place. Unless, of course, the skin holes are so badly out of whack with the spar holes ........ which is not likely. However, if at the end of the day you find yourself with a new skin, you will need to "find" the spar holes with some technique. I have found the best method of doing so is get an overhead projection acetate sheet - get them at any copy store - and tape it over the spar, marking the holes through the clear acetate. Then, WITH IT STILL TAPED IN PLACE, clamp down your skin on the spar and flip the acetate sheet overtop of the skin and then tape the loose end down. The marks on the acetate will be right over the spar holes, and you just then drill through the acetate to find them. It works like I charm - I know, as I have far too much experience at it!!!!!

From: Grant Corriveau <grantC(at)total.net>
Well, as is often the case, my faulty hook was a combination of a couple of small things with my amateur (very) building technique. 1/ I did have a 'negative' angle on the bottom of that hook so vibration tended to work it off the fully engaged position, especially as the tourque tube/spring pressures have 'worn in' (i.e. reduced) with use. 2/ There was some extra outward force on the canopy in that back corner from the insulation/foam grip that I'd applied around the baggage/turtle deck edge. (now cut away to provide definite clearance) The new hook is much more secure and Nicholas Heinz emailed me some good photos to indicate the way the hook tips must overhang outside the canopy sides.

Subject: 912UL Oil Pressure
I am having higher oil pressure than what I would expect with my 912UL. My engine is an older 912UL that I bought used a couple of years ago. The data that belongs to the engine states the max oil pressure at 72psi. If you look at current data, the max is now 100psi. I am running Mobil 1 15W-50 oil. It is in the 90's here. After starting the engine the first few times, the oil pressure ran 70~80 psi at idle. When I contacted Rotax, one distributor told me not to worry about it. I decided to contact another distributor for a second opinion. They told me to replace the spring that holds the ball against the seat, just off to the side of the oil pump. When I asked why this would lower the oil pressure, he had no clue. I ran it again today and got even higher pressures (up to 96psi). I have connected a analog pressure gauge to confirm my readings, so I have ruled-out the sender. Has anyone else had this problem? If so, did you replace the regulator spring to fix it? When I look at a cutaway view, it sure looks like that spring and ball arrangement is a bypass valve across the oil filter. Lockwood called the spring an oil pressure regulator spring though. Any help would be greatly appreciated! Thank you. Greg ________________________________________________________________________________

Regarding the issue of my original message, I want to thank Paul Hartl for his suggestions. They were similar those provided by Zenith. Looks like I've gotten it straightened out. What really solved the problem was taking a step back, and a break to clear my mind, then simply re-adjusting everything a bit. I removed the clecos from S9 and was able to slide the rear top skin enough so it now aligns with the Rear Zee. I'll need to put one A5 rivet at the #2 rivet from the rear of the S9 rib but everything looks OK . From what I can tell the skin slipped in (but not out of) the clamps as I was drilling the S9 rib. Guess I'll have to be more careful next time around!

I am building the 601 hds and with reference to 6-V-10 of the plan drawings and V-19b & V 20 of the step by step manual: I made the plywood horn positioning template exactly as per the specifications on V-19b and followed the directions # 31 on V-20, but I can not come near the measurements that are shown on 6-V-10 with regard to the 25mm from the center line of the 5/16th hole and the extended line of the aileron. Using the horn positioning template the distance is 42mm and the tip (5/16th hole) is forward of the rear Zee. I even made another template but the results are the same.

Bill, These were my comments entered in my journal for the control horns. I frustration on these is typical, because the drawings led me into what you seem to be describing. I solved the problem by what you read below. Control Horns for the Ailerons Jan 26 The afternoon was spent making horns like the plans. The matching surfaces and angles seem skewed a little even if only because of alignment with the top edge and the rib is perpendicular with the aileron. On matching up the aileron with the wing and fitting the horn, one discovers the horn has little to no down travel because it bumps into the zspar attach plate. The horn needs to be set rearward " and re-angled a little to reposition the forward edge of the horn ahead of the bottom 98 degree corner of the aileron " behind the horn leading edge. Some adjustment may be required in the length of the attaching push rod. Hope this is helpful Larry C.

From: Grant Corriveau <grantC(at)total.net>
I had a 'hiccup' (i.e. momentary loss of power) in my engine the other day on the way back to the airport. Does that ever wake a body up!! I thought that by insulating my fuel lines I'd cured the problem when it occurred last year one time on the ground on the hottest day of the year. Basically, it seems associated to a combination of 1) the chin-mounted radiator sending it's heated air through the engine compartment and 2) Honda has a stock feature that preheats the intake manifold (and so the base of the carb) with engine coolant. This works fine in cooler weather, and apparently helps with engine emissions, efficiency, etc.... but in a tightly-cowled aircraft installation cruising at 5,000 rpm in hot hot weather, this feature is undesirable. Other CAM100 operaters have done things like running this pre-heat circuit through their cabin heater, so that it is switched off in warmer conditions. I've confirmed that my carb bowl, and firewall-mounted Facet pumps can get up to temperatures in the range of 50 to 60C (140F) which is definitely getting to the fuel boiling-point range, so I'll be making some mods before flying again in hot weather. I'm going to deactivate the manifold preheat somehow, and add a jet of cool air blast onto the fuel pump/lines and maybe add shield of some sort to help protect them further. Solve one problem, move onto the next... ;-) While researching fuel, I came across the following site that contains some good information for mogas as well as avgas: http://www.eagle-racing.com/fuel.htm -- Grant Corriveau Montreal Zodiac 601hds/CAM100 C-GHTF www.theWingStayedON.ca ________________________________________________________________________________

Ihab, Thanks for your note, The drawing/photo shows a concept, I haven't implemented it yet. The plan is to replace the root hinge pin with a torque tube located on the same center. The torque tube would be affixed to the flaperon. A bearing block on the inside of the fuselage would be made to provide support for the torque tube. The bearing would have to be canted because the fuselage side is not perpendicular to the flapeon axis of rotation. On the inside end of the torque tube, there would be a bellcrank with the same length as the outer bellcrank in ZAC's design. I retouched the photo (of a completed 801) to show how the redesigned linkage would look. Jim Frisby N801ZA >From: "Ihab A.B.

In my mind, the internal bellcrank would be welded to a 1" OD tube, the external one would be welded to a tube that would fit inside that, they would be connected by a thru bolt or two.

Damien, I have a tow bar I got from Aircraft Spruce that is designed for a Cessna. This bar has the handle you pull out to spread the tow bar ends. Due to the depth of the 601 nose wheel, I had to move this handle back about 2 inches. This only required that I unbolt the one bolt, drilling a new hole, and replacing the bolt. I then dipped the tow bar ends into a solution that is normally used to coat the ends of hand tools in order to put a rubberized grip on them. This makes for a nice no-slip and soft end on the tow bar. To use this arrangement, I place the tow bar on the bolts that stick out of either side of the nose gear and are used to bolt in the fork doubler. This arrangement works very well and the tow bar even has the handle that slides into itself. This allows it to fit into the 601's baggage compartment. I am sorry I don't have pictures or P/N's but email me and I will get this to you if you so desire.

Although you will need to pull some test rivets to satisfy yourself that you've got it right, here are the dimensions of the dome depressions as measured on my heads: A4: 0.220" diameter 0.026" deep A5: 0.260" diameter 0.036" deep I used my dremel tool to grind what I thought were pretty good dome shapes into my rivet heads, and then took them to the Zenith Rudder Workshop that Flypass runs near Kitchener. I asked Art Mitchell to check them out, and he ground them out some more... The dimensions above were measured after Art was finished. After grinding you may want to slightly polish the surface of the head using 200 grit wet sandpaper and the head chucked into a drill press. You don't want to make them really shiny though or there may not be enough "tooth" for paint to stick well. The rivets take on the exact shape of the rivet head, grinding marks and all! - Murray scratch building 701, pieces all over the place. ________________________________________________________________________________

Mark, Nick will sell you the plans for just the XL Canopy if you ask. I did this and have recieved 4 drawings that are more than enough to go with. You may have to buy some parts from Zenith, like cylinders and locking hardware and there may be some differences that require a little of your own interpolation going from side to forward fitting canopy bows etc. I've not begun the canopy frame yet, but it's getting close.

Mark, There are a set of plans on the Zenith XL web site. I am just finishing up my front opening canopy. I might warn you that the are errors and omissions in the drawings and the dimensions have to be changed to fit the HD. Overall I am quite happy with the way mine is turning out. I fabricating all the parts myself ( just the excuse I needed to buy the MIG welder) and made some modifications. Such as mine has a key lock built in and the emergency releases that don't require a screwdriver. Another point which I had heard in the past from this group is that the rear hoop is nowhere near the shape indicated in the drawings. I'm glad I bent my own, if I had paid $60 for $2.00 worth of bent aluminum and still had to bend it that much to make it fit I would have been steamed. Contact me if you need information on sourcing some of the parts. The only really expensive part was the canopy itself. All the rest of the materials probably added up to less than $200 ( not including the welder) Tim Shankland mawood(at)zoo.uvm.edu wrote: > > Hello, > I just called Zenith about ordering a canopy for my 601HD.

So, it looks like I have a comfortable place to stay... Dave 701" Dave, This will be my eight year there and from past experience here is my .02 worth on the mater. You will have a wonderful time flying into Oshkosh! You have memorized the notam so I wont go into that! (grin) Things to remember: Have LOTS of fuel... and save a tank just for the approach you do not want to be switching when close in. You may have to circle for quite a while if it gets busy. Get atis as early as you can! It will be long and take a while to understand. Aim for Rippon or actually Green lake just west of Rippon. It is important to get to this point exactly with your eyes outside the plane! You want to be down to the notam altitude at this point. If you are low wing be about 100 feet low, if high wing about 100 feet high. Keep your eyes open! This is the most difficult part of the flight, aircraft are coming from all directions and descending to form a line. Coming from the west allows you a better view of them (assuming you are not arriving at dawn!). Have clean windows and all lights on! If you have others in the plane have them point out other planes. Remember there are 12,000+ others! About 8% of the worlds active aircraft! Rock the wings often so you can see around them and so others can see you. Now that you are at Rippon the rest is easy! The navigation is IFR (I Follow Railroad) or just follow the plane in front. Know the heading by heart so if you wander off while looking for other planes you can return to the correct heading quickly. Listen to the controllers, do NOT talk unless you have a problem. It is so ingrained to respond to ATC this is much harder than you think! When they ask you to rock your wings ROCK them! You don't need knife edge to knife edge but try to give them 30 degrees. They get tired of trying to watch someone just wiggle the ailerons. Use LOTS on control travel. Listen for the type and color of the plane you are to follow and try to get a POSITIVE id on it. (Oh, and be sure and know the type and color of what you are flying! I know this sounds dumb but you would be surprised how many do not!) There are a lot of planes in a line. If you have a passenger have them keep contact on the plane you are told to follow, then you can watch for others and navigate. Keep your speed so you stay the same distance behind the plane in front. PLEASE keep the speed that is correct for your altitude do NOT fly slower unless you are closing on the plane in front of you! This is really important; lots of the planes will be really struggling to stay at the low speeds. As you turn base you can start to adjust your speed for landing. ATC will tell you where to land. Make a normal landing this is not the time to prove you can stop in 100 feet! Taxi off the runway as instructed in ATIS. This usually means just turn off at any point, but be sure to turn the correct way or it will be a LONG taxi. Hold up your sign saying where you are going (see EAA web site) to everyone you see. They will direct you to the parking. This is the most difficult part! Have patience and keep your eyes open so you don't end up pointed at someone else's spinner! When you turn in to the parking spot don't power in if there are aircraft behind you, just turn and then pull it, you will make lots of friends that way! Have FUN! The flight is not as harrowing to fly as it is to read about. It is really very civil, just take your time, keep an eye out, and enjoy it! It is no real different that any other busy field (except the controllers are MUCH better). If you have bad weather or get cold feet for any reason land at one of the outlying airports, there are a lot of them. Or go to one of the "relievers" and take the bus in. But if you can OSH is wonderful! Have a GREAT flight! Randy http://sbc.yahoo.com ________________________________________________________________________________

Subject: Oshkosh Tips, for those that drive
Good morning all, I was just in my chat room and one of the members of this list popped in to say "Hi" and then went on to say that he was going to OSH for the first time this year and would be driving there. Well, I've done that too, the first few years I attended and thought maybe some of the others here who have never been there before could learn from some of the mistakes I made those first couple of years. First of all, once your past the EAA museum you will encounter a lot of people trying to persuade you to park in their private parking lots. Ignore all of them! Many first time visitors pull into these private lots only to regret it later when they discover they have a 1+ mile (1.6 km) walk to the actual entrance to the EAA grounds and see that there was ample parking available in the EAA parking lots. Second, get there early! The EAA parking lots open promptly at 6 AM. If your there then you will be able to park within a few feet of the entrance points. The latest I ever arrived was about 7:15 AM, on a Thursday morning 7 years ago. On that day I was still able to park within a couple of hundred yards of the entrance, but the parking area was filling fast and had I been 20 minutes later the walk would have been considerably longer. Third, food and beverage prices at the show are outrageous! As long as your driving in, take a cooler and have plenty of food and beverages in it. Chances are that since you parked so close your going to be returning several times with bags of information, catalogues, and freebies that are handed out. You may as well eat and drink the food you bring with you and save yourself the $15 you would spend on a burger and soda at the show. Fourth, be sure and bring along a comfortable camp chair for the afternoons airshow. These collapseable canvass chairs are available at K-mart or Wal-mart for about $6 each. They also sell them at the airshow, but they are triple that price. Fifth, If you plan on visiting the sea plane parking facility, mosquito repellent is a very good thing to have. Sixth, be sure to have an ample supply of your basic necessities like film, batteries, sunscreen, etc. Seventh, If you forget your camera, get to the Cannon photo booth which is next door to the press booth. These are located directly North of the the tower. Cannon gives out a limited supply of digital cameras to use for free each day. Each camera is capable of taking about 60 pictures. Once you have the memory card full you simply turn the camera back in and they will dump the pictures onto a CD and give it to you, for free! I've utilized this service for the past 3 consecutive years, I love it, but you want to be at the Cannon booth right when it opens, lots of people know about this and these cameras go out fast. That is all I can think of at the moment. If you have any specific questions please feel free to contact me directly or ask them here at the ZAC list. I get the digest and read it each morning so any responses will appear the next day.

HI John I just clamped the two pieces in a vice and banged away. Since they are so small they will not be a problem. I don't think you have enough material to put holes big enough to help you into the rib. Just a personal opinion but I would go for the Fiberglass tips! it looks neater and I have been informed by a high time Zodiac flyer that they do make a difference in handling.

I've finished the outer wings of my 601, including running the high voltage cables to the strobes. I plan to put the strobe power supplies in the cabin somewhere, so the strobe cables will need to run through the wing joint. Has anybody else done their strobes this way? If so, did you break the high voltage cable at the wing joint, and what kind of connector did you use? In retrospect, I should have put the power supplies in the outboard wing tip, but it's too late now. Thanks for any advice or info.

I've finished the outer wings of my 601, including running the high voltage cables to the strobes. I plan to put the strobe power supplies in the cabin somewhere, so the strobe cables will need to run through the wing joint. Each of my Zenith supplied strobe sets had its own separate unit independent of each other . FWIW, I put the strobe units on the inside end rib of the outer wing and ran the strobe cable diagonally through a 1/2 in polyethelene (water piping) "conduit" behin\d the wing tank out to the end rib. This way the weight is out of the wing tips and the units are accessible at the outer-center wing joint on each side. Only the power cord is divided this way in a molex plug in the event of wing removal. The strobe cable is in one piece and the wingtip would not have to be dismantled to service the unit. A new strobe wire could be pulled if needed by removing the strobe light and fishtaping a new cable out to the wingtip through the light mounting hole via the conduit. The strobe cable shield is grounded only at the inboard end not at the outside end for radio static supression. Good luck. LDP --- [This E-mail scanned for viruses by Netwitz.

07/12/2002 12:13:50 PM Why not put the stobe power unit on the inboard side of rear wing rib #6? I located mine there and just riveted it in place with 6 A4's. I fits nicely between the two front lightening holes and this provides easy access. The harness needs be be shortened or you can just bundle the extra wire. I ended up buying a crimp tool for mate-n-locks from Electric Bob and ordered some extra pins from Mouser Electronics. Both companies are on the Net. In fact I decided to use Mate-n-Locks everywhere. They are used on many certified Cessna aircraft. I bundled all the wires coming out of each wing at the Strobe unit location and added a connector there for easy detachment of the wings. This allowed me to avoid splicing the Power wire on the strobe unit. I grounded the unit to the #6 Rib using an A5 rivet and washer. The fewer connections the better.

Jeff Paden, For those of us not familiar with earlier Chris Heintz designs, I believe that the list has a general interest in learning about the characteristics of the earlier models. Especially those models no longer available. On occasion I have wondered why they were discontinued. Was it solid rivets vs. blind? To my knowledge, this information is not generally available. Maybe it should be added to the Zenith site. All that I find there is a diagram of the Design History with no explanation or descriptions. This is the history of the designer and related companies that most of us have some level of commitment to. Certainly everyone that has committed to building by buying Zenith/Zenair/AMD/etc. products does. I saw two 250's at Sun-N-Fun and wondered about those too. My impression, however, is that there simply aren't too many 250s and 300s in existence. At least not in the US. I would certainly like to hear a comparison between the 300 and the 640. Is there a clear genealogy? The chart indicates that there is a "design relationship". I presume that you have some knowledge in that area since you made the decision to change. I certainly understand your reluctance to place sales information on the list, and that probably is appropriate whether it is a rule or not.

The CH-300 is very similar to the CH-640, the big difference is that the CH-300 is smaller, hence the 210 pound limit on the rear seats and it does not have an area for bagage... well not large enough to call bagage any ways. If you want to see the aircraft I have a few pics on my web site at http://www.madbbs.com/~jpaden The pics can be found at the bottom left of the page under the link that says MY CH-300. My web page is not very pretty and the pics are just in a directory that you click on the file you want to see, but it will show you the aircraft. This aircraft was built by Bob Andrews and I purchased it for something to fly while building my CH-640... the problem with that is that I find myself flying more than building and I need the cash to build my CH-640. I have flown it to Sun-N-Fun and will also fly it to Oshkosh on the 23rd.

(see largeassembly/wing to center section) I like the tinnermans a lot for the ability to hide under the edge of the top skins. It's the wing-angle that holds the edges down. Hope this helps.

Mike, Absolutely it would be a problem. The flow from the tank to the gascolator must be down-hill all the way, so that any water in the tank will go down to the lowest point where it gets trapped. Imagine if you got some water in the line to your selector, it would settle in the lowest point. If you fly in freezing temperatures it could be upsetting. Or just the weight of the water could cause a flow lock. Dave Austin 601HDS - 912 ________________________________________________________________________________

I haven't seen the plans but why are you changing them? The number one reason engines quit is lack of fuel. Screw with the designed system and odds are you will have a fuel delivery problem.

HI Mike Since your building the XL like me think about installing an Andair fuel selector just behind and slightly above the gascolator which is between the two seats with an extension arm and a universal elbow then you can install selector portion remotely in the center panel just in front of the "Y" stick your fuel lines will not have to be raised and it will look great. Also I just spent a little time with Chris Heintz on Saturday and I asked him about the plumbing for the 4 leading edge tanks on the XL. His response was to install two pipes between the two tanks one low and one high with no vent line on the inboard tank. This basically makes it two large tanks with simplicity to boot. He also suggests that as habit you should always switch tanks every half hour. As I had a chance to peek into the Zenair shop there will be no new surprises at Oshkosh this year. IT would seem that attention was placed on other avenues over the last 6 mos and physical development of new products came to a screeching halt. But I sneaked a peek at the wings and WOW is all I can say ! My next trip up will be later in the fall. Hope to be able to share a bit more with you all at that time.

> I haven't seen the plans but why are you changing them? Ummm...if you ever get the chance to see the XL plans, you'll soon discover that there isn't squat concerning details on running the fuel lines when you install ZAC's auxilliary tank "system" (yes, I contacted ZAC, and they simply say they don't have them yet). So, I'm faced with either waiting for them, or trying to figure out how to plumb four tanks on my own. The plans only indicate a separate shut-off valve per tank (I guess you only run one wing tank at a time, or both through a "T" fitting?). But it doesn't indicate what to do when you have 4 tanks....so I figured a selector valve would be the way to go. Plus, I've seen HD & HDS photos that seem to indicate others have placed selector valves on the center console. Given the cautions I've received, I wonder how they got away with that.... But I do appreciate the good advice, and I will avoid the "up and downs" in the lines. Now I just need to figure out a good alternative. :) Mike Fortunato ________________________________________________________________________________

Now I just need to figure out a good alternative. :) Mike, As I understand it, you can run the lines the way you wanted, but you have to provide a way to drain the fuel at EVERY LOW POINT in a run where water could collect. So, for the sake of simplicity, it is good to keep the reversals to a minimum. But what form 'simplicity' will simplicity take in your design? Sometimes it might be easier to have an extra gascolater/drain point than to have to fabricate some sort of complex selector valve... ? On previous HD/HDS wing tank set ups, builders with 4 wing tanks have plumbed the two in each wing together into a T so that they can operate them as effectively 2 larger tanks. I wonder if this would work on the XL? -- Grant Corriveau Montreal Zodiac 601hds/CAM100 C-GHTF www.theWingStayedON.ca ________________________________________________________________________________

There is another way to get the fuel selector on the panel and leave the actual selector on the firewall. I was looking at the $200+ Andair fuel selector with extension and universal joints. It was way too flashy for my Pelican so I stuck with the plans. They use a $20 Weatherhead fuel shutoff valve (see Spruce, etc) and remove the handle, cut the shaft in half, then use an aluminum tube for an extension and mount the shaft and handle back on the extension tube. Lots of them flying for years so it works fine. Another neat trick is that you can drill out the fuel shutoff valve and make a left/right/on/off valve out of it for 5 minutes work and $free. Very clever people at Ultravia. I didn't like where it came out on the panel so I added a Sears 1/4" socket universal joint, and I didn't like the Weatherhead plumbing valve handle so I used a BMW knob from the automotive recycling facility. Those Andairs belong in Lancairs and RV's, this is a real homebuilders list ;<) Just an idea - I'd be happy to share more details.

I know I'm being a little anal here, but it bugs me that the location for crimps on the stab rib form is not in the plans like they are for the wing ribs. After looking at some pictures various people's web sites it looks like most ribs have 4 crimps between the spars, and the tip ribs have 3 crimps between the node and the front spar. Am I missing something in the plans here? I was looking at a rib blank when I was at Flypass a couple weeks ago. Art Mitchell had created the crimp positions on the rib form with a dremel sanding drum. They seem wider than what I expected. Art said he used a socket as a male dies to tap in the crimp positions. Seems straighforward. I was wondering how other people create their forms with smaller crimp positions?

But, I notice that the Zodiac XL tricylce >>only makes about 95knots in level flight at 2600 rpm. Is this the >>way the model was designed, or is it my setup. What are the >>cruise on your system? Hi Eric, I get a faster cruise than your 95 knots. I get 100 kts IAS @ 3,000 ft MSL and 68 degrees F, which translates to 106 kts TAS (or 122 mph). At 6,000 ft MSL and 57 degrees F, I get 98 kts IAS, which makes for 109 TAS (125 mph). I suspect that you perhaps don't have the "Automixture" option selected in FS2002, which means it will perform poorly at altitude because it is too rich. Check this under the "Aircraft" pulldown, subheading "realism settings". However....... I was at the EAA fly-in last Friday (in Arlington, WA) and spoke with Rodger about the XL and was surprised to hear him say it is a bit faster than the HDS. He claims 135 mph cruise @ 5,000 feet, which is faster than my FS2002 model; thus I need to modify the flight file - or you can do so easily yourself if you have the "Professional Version" of FS2002. If so, just use the "FSEdit" program to open the Flight Dynamics file and, under "Tuning", set the "parasite drag scalar" to 0.75 instead of 1.0. That should get you about 135 mph @ 5,000 ft MSL. I also noted that the Zenith demo 601XL is a more orange-red color than I painted it in FS2002, so I guess I need to modify that, too and get a modified XL up on my site soon with both fixes - give me a day or two.

As mentioned by Carlos, you can set those positions yourself. This being said, when I made mine, I considered the pitch 60 for the center ribs, but not the smaller pitch of the end-ribs.

If I was to do it again, I would have modified the crimps of the end ribs or I would have done new ribs to have a nice rivet pattern.... --- Carlos Sa wrote: > > > Hi, John > > > > I know I'm being a little anal here, but it bugs > me that the location > > for crimps on the stab rib form is not in the > plans like they are for > > the wing ribs. > > > > After looking at some pictures various people's > web sites it looks like > > most ribs have 4 crimps between the spars, and the > tip ribs have 3 > > crimps between the node and the front spar.

The Weatherhead fuel shutoff shaft is about 3/8" solid brass about 1" long. The handle fits over the "D"-shaped end of the shaft and is held on by a screw that goes into the end of the shaft. If you cut this shaft in half lengthwise, each end could be slid into the proper I.D. aluminum tube extension (I can go out and take measurements). A hole is drilled thru and each end is pinned with a 1/16" cotter pin. This allows the Weatherhead handle to be reused if you want, and the extension can fit thru a rubber grommet in the panel. In my plane the fuel lines meet at the center of the firewall from each high wing tank and go into the selector, then down and thru the firewall to the gascolator. The extension shaft brings the fuel selector handle right out to the bottom center of the panel. A picture is worth more than another page of description (or something like that) so I can take a picture and send it if you are interested.

Subject: cowling/muffler question
Date: Jul 17, 2002
Mark, I made my cowling based upon my choice of a nose bowl - which is one I got from ZAC. I assume that the nose bowl is for either a VW or the Continental. I mounted the nose bowl to 6 angles extending from the firewall, then wrapped sheet metal around the whole thing. It makes a pretty good looking cowling, but clearances are tight, especially on the 2 leading cylinders. The clearance issue, and the desire for a quiet plane (muffler size) are what drove me to hang the muffler underneath. Since the muffler is up tight against the fuselage, you can't even see it as you walk up to the plane; I have had to point it out to people on occasion. As to wind resistance, the muffler is your typical bullet shaped glasspack, so is at least somewhat streamlined. I also used stainless sheet clamps, which have a pretty small cross-sectional area. I don't think there is any impact on the power, as being a glasspack, it's a straight-thru 2" tube. Overall, I think the whole exhaust is non-restrictive. I had the headers and y-tube made by Custom Aircraft Parts in CA., and they stepped the tube size of each runner up to 1 3/4" right after the exhaust port, then joined the runners together into a 2" tube, that goes back to the muffler thru a couple of ball joints. The whole thing is 321 stainless. Hope this helps some.

Always glad to hear about someone else trying to keep it quiet. I got a deal on a Vance & Hines carbon fiber motorcycle silencer and I tried it on my Stratus in adition to the stock Stratus muffler. It quieted the engine considerably. I haven't run it with the silencer at full throttle but at lower rpm's it was as quiet as a car, I could barely hear the exhaust. It is a straight thru silencer that weighs under 5 lbs and is about 16" long with a 2" steel pipe. It is very expensive new but if you could find a used motorcycle silencer it would probably work great. The ones for newer high-tech sport bikes are built very well and are light. As a matter of fact, the first thing most guys do is take off the stock quiet muffler and replace it with an aftermarket one so there should be a bunch around.

My CAM100 radiator has worked fine since the get-go even though it goes to the the top limit on the 35C (95F) days we've had. However, I wasnt' getting enough cooling air around some of the accessories - especially the fuel pump and lines under the cowl, and also the carb bowl and the carb itself were getting too hot. I think I've solved this problem. I used the diagram from the Zenith web site to construct two NACA vent inlets. One I now use to bring cooler outside air directly into my carb inlet box. The second one I use to create a direct blast of cool air onto the accessories. I then also added an exhaust vent to help suck air out from the top of the cowling. The last two flights show marked reduction in the under-cowl temps. Grant, you might help cool the oil pan with something like this. Also, fellow-lister Doug Pahanke found a cooling fin that can be strapped onto the oil filter to help it become an oil cooler fwiw. --> Doug Pahanke wrote: ...You can get a finned heat sink and mount on the metallic crossbar perhaps, also on the oil filter.See this in the JEG catalogue/website, or JC whitney http://www.jcwhitney.com/product.jhtml?CATID=5217&BQ=mot -- Grant Corriveau Montreal Zodiac 601hds/CAM100 C-GHTF www.theWingStayedON.ca ________________________________________________________________________________

Last Saturday, after the first flight with my new Arplast prop, I pulled the cowl and discovered 2 cracks in my ZAC muffler. I called on Monday and Nick said they are now using a ball joint arrangement and, if I sent my muffler back, they would fix/convert it. It should arrive at ZAC today. If you have the Rotax 912 muffler where the pipes come from the engine and are welded to the collector without any other support you had better keep a close eye on them. By the way, the cracks were on the collector, just outside the weld area where the rear pipes attach to the collector.

Subject: cowling/muffler question
Date: Jul 18, 2002
Grant, Thanks for the suggestion about the oil filter, but I'm already trying something like that. I made a shroud that goes around the oil filter, and directed a 1" blast tube into the shroud from the cylinder baffles. Didn't seem to do much good. Last night, I made my latest change, which was to put a 1 1/4" lip all around the air exit at the bottom of the cowling (which is about 1.5 times the inlet size). I think my setup is now almost identical to a Cessna 150's. Again, not a lot of effect, though it did help some. At this point I'm somewhat baffled (pun intended ;-)). I'm curious about your top vent openings though. Do you know if anyone has done any tufting around the cowling to determine what the pressure distributions are? Mine feels like it's flying at a bit of a nose high attitude (I don't have ANY fairings on it yet, so it's REALLY draggy), and if that was the case, then the top of the cowling would be a low pressure area. Maybe I need to switch over to a top exit? Any suggestions are welcome at this point. Grant Schemmel a direct blast of cool air onto the accessories. I then also added an exhaust vent to help suck air out from the top of the cowling. The last two flights show marked reduction in the under-cowl temps. Grant, you might help cool the oil pan with something like this. Also, fellow-lister Doug Pahanke found a cooling fin that can be strapped onto the oil filter to help it become an oil cooler fwiw. --> ________________________________________________________________________________

Also the arm for the rear baggage shelf is shown at 55.1, which looks to be approx the front of the shelf. I would think these locations should be measured as close to the center as possible.

Also I have recently acquire this flow & consume monitor http://www.jabiru.co.uk/fuelmon.html. The point is that I doubt a manifold pressure gauge is needed since you can control the rpms and the good performance of the prop knowing the fuel flow ratio constantly.

When I did my W & B, I decided to calculate the arms by putting known weights in each area and getting the weight under each wheel. From those weights, and distances from the wheels to the datum, one can calculate actual arms for each item (fuel, baggage, passengers). I then put that in a spreadsheet so it's a snap to do a quick W&B. Greg Ferris FAA Inspection next Tuesday!

Kelly, When I did my W&B on my 601-HDS, I measured to the center of my header tank and wing tanks. As for the baggage area, I measured it in two places; the first place at 1/3rd length from the front to back and the second at 2/3rd length and assumed a maximum of 20 pounds at each location to simulate even weight distribution. I agree that we should measure at the center of everything, including the pilot and passenger locations.

Subject: Skydat GX1
Date: Jul 20, 2002
Hi, Bill, I have a Skydat GX1 in my 701 which I have owned for only 2 months. I found that it took no longer to get used to than any other unfamiliar cockpit layout. I have only 2 direct concerns and 1 indirect. I think the character size for the altimeter readout could be a wee bit bigger to give it more prominence. I find that sunlight on my body can be reflected back off the screen making it difficult to read occasionally. My third concern is that I would lose all instrumentation in the case of a power failure. I am considering a backup power system for this reason. Apart from these issues I am very happy with the system. I have the optional fuel flow meter which gives fuel flow and accumulated fuel usage which is very useful. I recommend it. I also have the digital compass from the same supplier and have found it to be very accurate and a heck of a lot easier to read than normal compass. In summary, it's good gear, it's priced competitively and it's certainly a viable (and lighter weight) alternative to traditional instumentation unless you are "old school" or have a high RC (Resistance to Change) quotient.

Subject: Screw Question!?!
Hi List, I just purchased my HSI for my panel and when I went to install it (it's always something) the screws are not long enough to go through the panel, and the light ring and then into the instrument. The instrument does not bolt from behind the screws actually go into the instrument. My question is I can not find a matching screw anywhere. It appears to be a metric thread and size but I can;t find anything in any hardware store locally. This would probably be easy to find if I knew exactly what to ask for. For size purposes, it appears to be between a 4 and a 6 machine screw but the pitch in the threading is different, and I need about 3/4" in length. The instrument is the electric HSI AC Spruce./ Does anyone have any idea what size screw I might be needing to look for and where I might find them. Thanks a lot guys.

It could be a No. 5, which magically is halfway between a 4 and a 6. It is a standard screw but not common. The major screw diameter is .125, the tap hole size is No. 38 wire guage (.1015") for the Course thread of 40 Threads per inch, the tap hole size for the Fine thread of 44 TPI is No. 37 (.104"). I suspect it is 5-40, I'd be surprised if it was 5-44 or metric, but I am surprised a lot these days! If you strike out everywhere else, I can send a 5-40 screw in an envelope for you to try, we use them in our product, so it's not a problem. Good Luck. Randy L.

Damien, You're right, the cables supplied are much longer than needed. Once you've established the cable routing you'll have to cut them to fit. Choke cables too.

Meanwhile, it should be noted that AVEMCO has specifically OKd policies on Zenith Aircraft. This according to ZAC July/August Newsletter. From other sources on the web, AVEMCOs problems with kit / plans built aircraft has stemmed from nearly crippling loses in the carbon-fiber and other composite birds. I read that Zenith and Vans are the only two designs that they will look at. Could it be "aluminum"? 99% of the Certified Aircraft are, we recognize, aluminum.

I also saw the -9.5 figure but I'm guessing that it refers to the small header tank, rather than the 16 gal one. An old owner's manual gave -3.9 inches for the bigger tank. I calculated -5" on the scales after partially filling my 16 gallon tank with 58 lb of gas. But don't take that as a precise figure, just as an example. The shape of the tank naturally means the arm will shift depending on the fuel load. Might not be a bad idea to measure the landing gear positions too. Small variations in those numbers (vs. whatever Zenith says) can significantly affect the calculated arms for other weights. (This is assuming one is calculating a moment arm rather than trying to measure physically. Both methods have sources of inaccuracy.) I've seen both +27" and +26.5" given in Zenith docs for the main wheels, while George Pinneo measured +26.2" in one of his on-line documents. The Zenith turtledeck baggage shelf numbers aren't very useful for watching out for any aft CG problems. The number I measured was +69" for the center of the shelf, where _in my personal definition_, I don't include the section ahead of the aft hoop.

> I expect one of you CANADIANS to tell us about the Gimli Glider episode. Well George, I don't have all the details at hand but it goes like this: Happened about 20 years ago, maybe more. Boeing 767-233, number 604 in the Air Canada fleet had a problem with fuel gauge indications on the ground prior to departure. Canada was in the midst of changing from imperial to metric measurements, and the 767 was the first aircraft type in the AC fleet to have metric gauges, thus plenty of confusion in determining how much fuel was actually on board. A couple of hours later, westbound at cruise altitude, both engines flamed out due to fuel starvation. OOPS! Now the 767 was a big glider. Landing in Winnipeg was the first choice for the crew but they quickly realised they wouldn't make it. Gimli, Manitoba was in the vicinity, a former WWII air force training base, but by then a drag race facility. So the captain put the 767 down at Gimli, with surprisingly little damage (hit a guard rail I believe). The airplane was repaired and remains in AC service today; in fact I have a number of hours logged on that airframe myself. Like George says, a great story to read.

Hi list, I my quest to find the right screw I never thought this would be such an ordeal. I finally had to take the screw that came with my directional gyro to a machine shop to see if they could decipher what it actually was. What they told me is that it is a metric screw, with a standard thread pattern, or 3mm on the outside diameter with a 40 for the thread. OK fine. No such animal exists in any of their experience, but a 5-40 or a 6-40 are both very close, with the 6 40 being closer mathematically. I have found someone who maybe carries a 6-40 in the length I need but it is a challenge. Who would ever have thought this would be so difficult. When I called the manufacturer of the instrument they told me they didn't know the screw size but said they would send 4 more that were a little longer. I'm not holding my breath.

As I recall, the aircraft was not only being controlled via the RAT hydraulics, but also had only minimal electrics - so none of the nice 'glass' instruments were working. Apparently Capt. Bob Pearson was using the VSI from the cabin pressurization system to determine his rate of descent -- after the cabin had depressurized (another side effect when both engines fail). I'd flown privately into Gimli several times in the year before this incident - it has two parallel runways - one of which has been converted into a dragstrip. The black ashphalt of the dragstrip shows up from miles and miles away, whereas the washed out gray pavement of the serviceble runway, is hard to see until you're almost there. Consequently, they landed on the dragstrip and the center-rail caught the nose gear of the B767, causing it to collapse. Too bad 'cause otherwise there'd have been no damage at all. Along with the more recent landing of the Air Transat Airbus A330 in the Azores(?) enroute across the Atlantic, you begin to think there's something going on with Canadian airlines, fuel and glider landings!!!???

Steve: I Would love to know how your "Machinists" determined the OD from your internally tapped thread in your instrument. Most production threading is not right on the money, so their deduction that it is metric diameter with a UN (Unified National, Fine or Course) thread is a real stretch. I have thread charts from "Machinery's Handbook" in front of me. The outside (major) diameter of a: No. 4 = .112" No. 5 = .125" No. 6 = .138" In metric 3mm = .11811" Let's assume we are all taking the same drugs and agree it truly is a "3mm x 40 tpi (threads per inch)", then the 4-40 screw, being slightly undersize, but with the same thread pitch would readily screw into your instrument. But you said you had 4-40's to try at the "hardware store", you know, the one where the clerk guaranteed you that there was no such thing as a No 5'! So if you tried their 4-40's and they wouldn't work, obviously the holes are not 3 mm, or the smaller No. 4 would have screwed in, You also had a No. 6 to try, were they too big? I'm still betting it's a 5-40. If you still can't find one locally (in Phoenix?) I can mail you a screw from my inventory to check your threads. It is not the screw you need, it is an example 5-40 screw for thread checking. Another Lister advised checking hobby shops for 5-40 as a readily available screw size. From the charts: a 4-40 is a course thread, a 5-40 is a course thread, a 6-40 is a Fine thread. This has been fun, keeps One from real work! Regards, Randy L.

Subject: Re: developed length, bend radius
Yes the dl is the lenght before bending the part and if you noticed, it is shorter than the sum of all side dimensions. The actual dl will depend on the actual bend radius you achieve and as a result, I found the plans specified dl to be an approximation. But in anyway, before bending any part, make sure to bend "test pieces" until satisfied. For each test, take note of how you achieved the bend so you can repeat the process for the actual part. You'll most likely find a way to use your pre-cut parts. Oh... on some parts, the dl was simply erroneous (I build a CH601-HD).

Philip, I have done some similar work on the radiator to help control the temp. The radiator installation provided by Zenith is marginal at best. I also installed neoprene rubber seals along the edges, between the radiator and the lower L-angle that runs the length of the radiator. Have you tried the high temp. exhaust wrap for the muffler and header pipes? This also cools the air entering the radiator, since the muffler is right in front of the radiator. Aircraft Spruce sells the wrap.

I did a lot of research into this topic before I got started on my project this year. The developed length in the plans is the pre-bend dimension you use to cut out the parts. The location of the bend lines, sight lines etc. you may need do not appear to be in the plan and may have to be calculated. The book "Aircraft Sheet Metal" available from ACS is very helpful on this topic. Jeff Kafka 601XL Plans on order, Rudder done.

I did seal off the rear of my radiator last year by fabricating a piece of .025 and fastening in place. I was amazed that doing so reduced my speed by about 1 or 2 mph at cruise, so it did create a little more drag. If you'll recall, about two years ago, I experienced a valve guide failure during flight in my Stratus-powered 601-HDS. The engine never overheated but many others attributed this to overheating. Since then, I have been overly cautious about how fast I run the engine and am constantly looking at the engine temps during each flight. My questions are: 1) What are your engine temps that you consider "normal" during cruise and climbs? 2) What are your props pitched at? My props are pitched at 15.5 degrees, so at full throttle my engine revs at about 4700 rpms and the airspeed tops off at 120 mph. I probably should reduce my pitch to about 14 degrees. Also, during the hot summer days, I cruise a little slower to keep the engine temps no higher than 210 degrees (cruise at 3800 rpms at 90 mph - real slow). During cooler days (less than 70 degrees), my engine temps averages 195 degrees at 3800 rpm, but averages around 210 on hot days. I rarely go higher than about 4200 rpm, or 105 mph. I'm going to try to seal the gaps on the sides of the radiator and the brackets to see if I can get better temps results. Have you tried that? Finally, I drew plans to use a cabin heater radiator to help with dissipating more heat to the outside and be switched to serve as a cabin heater as well. I'll let everyone know how this works when I get this done hopefully soon... Thanks, and fly safe!

All this talk about cooling the Stratus has me wondering about my installation. A few months ago I installed my radiator, standard belly ZAC style. After running my engine I've found several leaks around my hose connections (I probably lost a cup of coolant during my debugging process). I now have them all stopped, but I'm curious if I have to remove my radiator again to refill it & remove the air as we had to do before installing the radiator? Or will the air that got into the system by the leaks be purged and replaced by the coolant in the overflow tank? I haven't flown the plane yet, and don't want to see the water temp go to max do to a lack of coolant when I do. Thanks for any words of advice on this, Kelly Meiste 601 HD Stratus (99.99% complete) PS. While working on my plane last Sunday I had a few guest stop in (fly in) to check out my nearly completed 601. It was the ZAC team on their way to OSH! Who could ask for more! They arrived with 5 planes (601XL, 601HDS, 640, 701, & 801). Nick and Roger spent at least an hour with me! Poor ol Nick was kind enough to climb under, over, & inside my plane checking it out (this was a 95+ degree day). That was pretty good of him, especially after he just finished a 2 hour flight in a hot 601. And as they left they all complemented me on the fine job I did on the plane!

Kelly Congrats on your getting the Zenair team to visit and admire your work. Like you, my smile would indeed be as wide as my hangar door if I got such as an honor. If you only lost a cup of coolant during your test, you mostly likely did not get any air in your cooling system because the coolant, one flowing, is under pressure. If the pressure remains or gets low because of the leak, the system would replace the lost coolant from the overflow bottle. Before your next test, check if you need to add more coolant into the pressure bottle. After your test and after letting the engine cool down, check the level again. Once the level stabilized, you pretty much have removed just about all the air bubbles that might remain in the system. Hope this helps...

I have been flying the Soob powered HDS for a year in SW Florida heat with no coolant problems (oil temp too high, but that's another story). I closed off the rear of radiator with a metal plate and used foam weatherstrip on the sides. I even raised the front of the radiator 1 1/4 inch from the stock position and saw no increase in water temp. This has me convinced the radiator is adequately sized for the engine and efficiency is determined by the volume of air forced through the core by the sealing measures I have taken. As for the purging of air, my experience (30 years of automotive and a lot less of aviation) has been that a couple heat cycles with the proper radiator cap (one with both pressure and vacuum valving) will usuqall purge almost all the air from the system. The exceptions to this are a couple vehicles where the cap is not the highest point in the system. I have placed my cap at the highest point and ran a few heat/cool cycles before the first flight. Temp never ran over 220 F with 50% glycol coolant and a 13# cap. Oil temp, on the other hand is running close to 250 and is being dealt with by the addition of an oil cooler. Coolant leaks are quite normal after the installation of new hoses used with SS worm gear clamps. A 10 hour retorquing of the clamps should be sufficient. This could be eliminated through the use of the constant tension spring clamps that the manufacturers are now using. Hope this long-winded post was some help.

A few months ago I installed my radiator, standard belly ZAC style. After running my engine I've found several leaks around my hose connections (I probably lost a cup of coolant during my debugging process). I now have them all stopped, but I'm curious if I have to remove my radiator again to refill it & remove the air as we had to do before installing the radiator? Or will the air that got into the system by the leaks be purged and replaced by the coolant in the overflow tank? I haven't flown the plane yet, and don't want to see the water temp go to max do to a lack of coolant when I do. Thanks for any words of advice on this, Kelly Meiste 601 HD Stratus (99.99% complete) PS. While working on my plane last Sunday I had a few guest stop in (fly in) to check out my nearly completed 601. It was the ZAC team on their way to OSH! Who could ask for more! They arrived with 5 planes (601XL, 601HDS, 640, 701, & 801). Nick and Roger spent at least an hour with me! Poor ol Nick was kind enough to climb under, over, & inside my plane checking it out (this was a 95+ degree day). That was pretty good of him, especially after he just finished a 2 hour flight in a hot 601. And as they left they all complemented me on the fine job I did on the plane! I thought I should pinch myself to see if I was dreaming, luckily my hanger has a WIDE door, so I was still able to get my head through it after they left. = = = = ________________________________________________________________________________

On page 7-A-2 and the Rear Splice Plate. The figure from rear of part to the location of the AN3-3A bolt is 40mm in the new drawings, but on the 3rd edition drawings, the figure is 60 mm. It looks to be the correct figure, according to the drawing of the part. Can anyone help me with this problem an confirm that the new drawing is incorrect with 40mm. Best regards from Iceland.

Hi George, I am just at that stage with my soob/701, and am considering which radiator to use and where to place it. Have you used the volks radiator? What model is it, would it measure about 330mm x 770mm ? Have you put it under the seats with front edge down? what does your scoop look like? thanks, TerryR...NZ I have been flying the Soob powered HDS for a year in SW Florida heat with no coolant problems (oil temp too high, but that's another story). I closed off the rear of radiator with a metal plate and used foam weatherstrip on the sides. I even raised the front of the radiator 1 1/4 inch from the stock position and saw no increase in water temp. This has me convinced the radiator is adequately sized for the engine and efficiency is determined by the volume of air forced through the core by the sealing measures I have taken. ________________________________________________________________________________

These numbers are also true for my HDS with EA81. I read somewhere that, from a purely scientific point of view, oil at 180F has an unlimited life and for each 10 degree rise that life is reduced by some factor. The water that accumulates in the crankcase would best be removed by elevated temperatures, so 200-220F would accomplish this while still giving some reasonable service life. I am in agreement with any mechanic who wants to keep oil temps low on an air-cooled engine, but how about a water-cooled installation? What happens at elevated temperatures? My contact at XXX Oil Co. says 250-280F is max. After that the additives break down rapidly. A recent certification test in the lab had a 3.8L Chevy running at 3600RPM (80 MPH) for 80 hours at 320 - 330F. (but he wouldn't recommend this for the real world). He obviously doesn't ever hear the word airplane from my mouth. Has anyone submitted a sample for oil analysis? Seems like the scientist types could tell how much life is left in our oil.

The EAA may call it AirVenture but for many it will always be Oshkosh. And for most it will always be about friends and airplanes - with the emphasis on friends. This year it was a double treat, first to meet up again with Zodie builders Fred Hulen and Bob "Ace" Wiley, and topped with introducing Aussie HDS builder Barry Mayne and his friend Iian Douglas to their first Oshkosh experience. Fred and I had "planted" the idea of a visit long ago and Barry took the bait. I'll let it to Barry to tell of his view of the 50th EAA Convention. The ZAC bunch were in the north exhibit area in their usual location. Got to talk with Seb, Nick, Roger and Chris for a few minutes and then left them to their task of answering questions for potential buyers. They had two 701's, an 801, the XL demonstrator, and the 640. Walking by the site the next day saw a 2000 with the blue/yellow 701 having been moved to the ultralight area. Rows 22 and 23 in the Homebuilt Show area always have the Zenith products. The Flypass 801 was there Monday and Tuesday with four 601's: Dennis Carley in a very nice white HD (detailed pixs can be seen on Michel Therrin's site), Cleon Maxwell in an HD with his own forward opening canopy design (he has posted pixs to the matronics file), Stan Challgren flew from CO to Mexico and then headed north with the ZAC crew in his Jabiru 3300 powered HDS, and Bill Nichelson in his HDS/3300 "Casual Passion." Someone said another 601 was there for less than a day. There is nothing "casual" about Bill's a/c, with detailing everywhere. Self-designed double-cam forward opening canopy, wonderfully slick yet hidden latching system, homemade NACA vents with operating doors that close flush, a homebuilt metal cowling that looked so good the factory should adopt it RIGHT NOW...the list goes on. A truly impressive piece of workmanship. All of the Zodiacs present reflected the involvement of their builders and the fun they were having in flying them. It's very, very possible that other ZAC a/c were there but we couldn't get everywhere. Met up with builders Dave Alberti and Wayne Beattie (Dave will fly soon) at the show and then talked with 801 builder Phil Owens at the Jabiru BB&CR. (Beer, bratwurst, and corn roast - after all, it is Wisconsin). Phil seems very pleased with using latex paint to finish his 801, maybe when finished he'll detail things for the list. Airshows were the typical OSH usual - great performers, lots of acro, warbirds by the dozens, and announcers that never shut up. Sean Tucker is always a crowd favorite and Manfred Radius' sailplane routine added some variety. The weekend shows have a longer warbird segment. The EFIS/Compac type units seemed to draw crowds at every booth that had some variety of them to sell. I figure that if I wait four years the size will double and the price will be half - hey, I can dream! The Garmin GPSMAP 196 had guys five to six deep around demonstrations. Show prices hovered near $869 (retail $1049) and you could get it shipped home free without taxes...so, "Honey, I just saved us almost $230." It has so many features that I don't know if I can remember how to access/use them all. EAA, AOPA, AvWeb, all have sites that will tell you far more. Get on the Garmin site for 196 info.

Still, it says something about their priorities with retard to new customers. 2) A sample prop and floats were shown from Skyshop - a marketing agent for Czech Aircraft Works in the US (www.skyshops.org) (but separated for the usual reasons, I suppose). Props, from "Woodcomp" - a combination of two outfits including Kremen - include adjustable models (some, in flight) but I didn't discover if any of these apply to Zenith models. Both builder assistance programs (seven days; one is flown to Czech Republic and the completed craft sent to the US for 51% approval) and 100% planes are offered.

Hi List, To the lister who suggested 5-40 as the right screw to fix my problem I humbly bow and extol "I'm not worthy!" That screw did the job although it was very difficult to find, the proper head type was not available at hobby stores and I ended up at an industrial fastener comapny. And even though I now have the proper size and thread pattern the proper length is still not for sure determined. The longest this comapny stocked was 3/4 inch, and I think I need 1" which would be a special order. I should know within a day or so, but as with so many other aspects of this project, one success allmost always breeds another challenge. I now have to file out a notch for my push to cage nob.

Subject: The bends
Hello, folks Three years after starting this project (less 12 months in "hibernation"), I found an 8' bending brake (a must for scratch building). And this at a kit manufacturer 100' away from the airport I fly from! Anyway, I spent all day Thursday in their shop. A couple of hours were wasted trying to figure how to get the 1/8" bend radius. I new people usually bend and leave in place a bunch of fillers, but working with more than one filler proved to be not feasible: the fillers would not stay in place and the tool would not clamp (or would take a lot of strength to do it). The only person that uses it in that shop (it's a small operation, as - I believe - most kit planes manufacturers), told me he uses a single filler of .020". Knowing the 1/8" radius rule is a simplification, I made a filler .040" thick and bent as many parts as I could - until a splitting headache and a couple of bad results suggested it was time to pack and go home. At home, I measured the radius in the parts I made by dropping a drill bit inside the curve. The best fit is a 5/32" bit, or 5/64" radius (.156" diameter, .078" radius). According to table 4-6 in AC 43.13, this radius should be adequate for thickness > .032", going up to .064" (for each thickness the table gives a range for the radius, like 1 to 2 times the thickness). The thickest parts I bent are .040". My conclusion is that all is well, but I sure would rest easier if someone would drop me a line agreeing (or disagreeing) with the above. Thanks in advance Carlos CH601 HD - one rudder done, 185 parts made - less six rejects from the bending session. ________________________________________________________________________________

I noticed, 2 times radius against material thickness works more than good.

List builders, I think the most interesting new engine offering seen at Oshkosh for the Zenith, lighter weight birds, was the Raven Redrives 1300 SVS. This 4-cylinder Suzuki engine lay flat with a belt adaptation 2 to1 or 2.26 to 1 reduction and was said to develop 90 hp on 165 lbs. They beat 912s on cost. It's a lot simpler than most and had a really thin profile. This would seem a great engine for the 701s.

Great that you found a break to use Carlos - that radius requirement certainly slows down the less-brave builders (like me). My bigger problem is not the radius - its getting the bend in the right place. I have a small 30 inch brake and get a 1/8 radius by using a piece of stair nosing instead of the zero-radius leaf (or tongue - just what is the the proper name for this???) that came with the break. I can get access to larger brakes to do by stabilizer spar but thought I better master the "art" first with bends on my smaller break first. I have been experimenting on test pieces and a couple of small parts. What a pain!! Let's just say my success % is pretty pathetic. I'm just glad I decided to play with smaller pieces first before I ruined my much larger stabilizer spars (which are waiting to go on my table). How do people line their work pieces up in the break? Do you use the bend allowance, tangent line, sight line method described in the Bingelis books? Or is the simple method to get a sight line mention in the Zenith Assembly guide good enough? I have already realized that the simple rule of thumb just mentioned is not accurate for the two 1/4 radius bends I just did- dohh!! I have seem many pages refer to mistakes with bending - but they don't give much detail on typical mistakes - and how to prevent them? Boy, I wish they did some bending as part of the workshop when I did my rudder at Flypass.... Methinks it is time to visit some people for some hands-on instruction! regards all, John M. 601XL scratch building - rudder pretty well done, starting stabilizer, long way to go Carlos Sa wrote: > > >Hello, folks > >Three years after starting this project (less 12 months in >"hibernation"), I found an 8' bending brake (a must for scratch >building). >And this at a kit manufacturer 100' away from the airport I fly from! > >Anyway, I spent all day Thursday in their shop.

07/29/2002 06:45:58 AM John, I found the simplest way to get the right measurement is to cut your pieces oversize, bend, then trim to correct size. I never could get it right using the formulas.

What I do is, for every thickness and for every angle, to prepare a rectangle 1 to 2 inches wide by 4 to 6 inches long. I graduate it (across) with parallel lines, 10 mm apart. I then place this sample on the bending brake and align a chosen reference line (near the middle) with the brake's clamp (or tongue, or whatever - the part that holds the sample in place). After bending it with the desired angle, I can measure the location of the bend in relation to the placement of the part on the brake and, if necessary, compensate when I bend the actual part. Of course, a successful test before committing is advisable. BTW, if you want a bigger brake (48"), take a look here. I made one like this, but made it long enough so the rudder spar would fit.

There was an article in, I believe, Kit Planes re: bend set backs. I scanned and saved it. If anybody wants, I can post it. It appears to be very accurate for the little I tried. alex ________________________________________________________________________________

Hi Clyde, thanks for the tip. I remember from inspecting an old altimeter a long time ago, that loosening the screw and pulling out the knob will disengage a gear drving the barometric pressure indicator (or altimeter hands - I don't remember anymore). Anyway, I have tried that, but can't get the knob to pull out. Maybe I'm not doing it right. Your description is not clear do me. What exactly do you mean by "slide it over"? Thanks a lot for your help. Also, thanks to the other folks. I'm hesitating to send the instrument back to A/S. You might remember, that I relocated to Europe. The service of A/S in the US was already not the best... Besides, shipping of instruments accross borders is a pain with customs. Thus, my first option is to get the altimeter fixed by myself.
