    Subject: Re: CZAW cowl question again
    Ben I understand where you're coming from. Keep in mind however that I'm using a Rotax 912 engine where they specify the oil temp range based on a manual for a new engine. The oil temp reading on 912 engines since at least the mid 90s are taken at the oil pump housing after they have gone through the oil cooler. They state a max temp reading of 280F in that location. My engine dates back to at least 1990 according to the serial number and I've been dealing with quite a number of differences in my engine compared to newer ones of which the oil temps are one of them. The location of my probe is not in the newer location on the oil pump housing but on the front oil return line fitting where normally there is plug (or a banjo bolt for pusher configurations). I've reported that I get a highest reading of 260F which is till within the 280F max temp according to a newer manual. I'm assuming at this point of course that the oil is bound to be hotter here but I don't know by how much... This is why I don't know if I should try and mod the cowl to get them lower when they actually might be well below what I'm getting or just accept them since they are bound to be hotter. I have a new VDO probe designed for current engine location but I can't use it on mine because the threads and hole size are different in my oil pump housing! Rotax changes the 912 constantly is this is just one of the little things that I've had to deal with... I have a friend with an engine of the same vintage and I'll check with him to see where his oil temp probe is and perhaps try and correlate my readings with his.

    Subject: Alternator Recommendations
    From: "Wingrider" <rwhitt3@HOTMAIL.COM>
    Hi, I am new to the Matronics newsgroups although I have been reading the post for a while this is my first time writing in. I'm building a Zenith 601HDS and will probably go with William Wynne's Corvair conversion. I'm trying to figure my electrical loads before installing the landing lights and closing up the wings and don't believe the typical JD garden tractor alternator is sufficient for my application; I expect a full load amp draw of between 35 and 40 amps. Maybe I'm way off base and maybe I shouldn't use a pair of 100 watt off road lights for landing lights. I'd like your recommendations for a small lightweight automotive alternator. From what Ive read it sounds like I should stick with the three wire alternators and shy away from the one wire versions but are there recommendations for specific alternators? There seems to be differing opinions on the whether the load dump issue is a real concern or not. I understand Bob Nuckolls is working on a product to nullify the concern with using internally regulated alternators. Is there any news on this product at this time? Attached is my initial swag at my electrical loads. -------- Rich Whittington Tullahoma, TN Zenith 601HDS Under Construction Read this topic online here: http://forums.matronics.com/viewtopic.php?p=78119#78119 Attachments: http://forums.matronics.com//files/ch601hds_electrical_loads_analysis1_852.xls

    Subject: Re: Zenith-List Digest: CZAW Cowl Question Again
    Initially, in our CH601HD with R912S, the oil and coolant temperatures were too high. Two fixes took care of the problem. The first was to increase the airflow EXIT area by cutting out quite a bit of fibreglass. An increased intake area won't do much if the exit area is too restricted. The exit area must be much bigger than the intake area. [However, this fix can be uncertain if the lower back exit area of the cowl has a down-turning lip on it. This lip, if present, creates a low-pressure area beneath the cowl to SUCK the hot air out. My point is, if this lip is present on your cowl (it wasn't on mine, but I've seen it on a CZAW-built 601XL), I wouldn't mess with the exit area.] The second fix was to make sure the intake duct was a close fit around the radiator so that the air has to go through the rad, and cannot escape around the edges. We added fibrglass strips to improve the close fit. We did NOT increase any intake areas. John Goodings, C-FGPJ, CH601HD with R912S, Toronto/Ottawa/Waterloo.

Prior to the start of the workshop they painted everyone's aluminum rudder pieces with Cortec. So I figured I'd go with what they did and use it. I just didn't know if I should put it on quite as thick. I think there is an additional benefit to Cortec - it's sticky, and after the parts are riveted together it will be like "rivets plus glue". Would add more shear strength I would think. But would also harder to slide parts around, like fitting a piano hinge between two skin sheets for example. - PatrickW Read this topic online here: http://forums.matronics.com/viewtopic.php?p=78157#78157

    Subject: RE: Alternator Recommendations
    I bought a 45 amp internally regulated alternator to install in my HDS Corvair, and sold it after figuring out that there is no way to make it fit under the nosebowl. If you are going with the WW Corvair conversion, the small dynamo is the only thing that will fit. Your only other option is to mount the alt in the back of the motor, which will require a little more work than just buying parts from William and bolting them on. Not too much work, but more... IMHO, load shedding, and possibly going with smaller lights, and LEDs when possible would be easier than engineering your own alternator setup. You can purchase the overvoltage protection unit from Bob. I have it installed in my aircraft. After having a regulator fail in a Citabria, and frying the battery, I like the idea of having built in overvoltage protection. He now also has a low voltage indication BAMM unit now, but I know nothing about it other than what it says on the website. R/ Brandon ---------------------------------

    You could go with a set of HID off-road lights. J.C. Whitney sells a pair of KC Hilites for about $640. They're a bit pricey but they put out three times the light for less than half of the current draw.

    Brandon, Congrats on getting airborne! Noticed your tailwheel upgrade comments and wondered if you would share some info on the Matco installation. I'm just starting on a 601XL taildragger and would prefer a swiveling tailwheel versus the stock fixed wheel. I'd like to know what was involved in the installation versus the fixed wheel, if it would be a significant rework project if installed at a later date, and where I can find additional info. Appreciate any response you send.

    From: "Gig Giacona" <wr.giacona@cox.net>
    Congrats on your first flight. What prop and pitch do you have? [quote="btucke73(at)yahoo.com"]Gents, Finally got the aircraft flight ready again this morning and took her up. 601 HDS / Conventional gear with aluminum spring Corvair bored .060 over - standard WW conversion Calsbad, Ca. SKC / 60 miles vis / 65 deg Climb out was less than expected at about 800 FPM at 3000 rpm. The engine sputters just a little bit at full throttle, so this is the performance cracked just a bit from full. I have to tune in the aerocarb a little bit this week. I am still indicating high oil temps, so a new sender is on order. Indicated temps are not jiving with laser temp finder on the ground. It required full right aileron trim to go hands off. More flight stuff to follow in the next few days... Some things to mention. DO NOT waste your money on Azusa brakes. They couldn't slow a piss ant's motorbike. I bought a hydraulic disc upgrade from GPSAC, and after a little bit of fab work to install, they work much better. I still saved a few bucks from the Matco setup, but it was not worth the heartache. Also, for the tailwheel folks, I would bypass the tailwheel from the plans altogether. I installed the Matco full swiveling taiwheel this week, and love it. It is a very good deal at under $150, and installation is a piece of cake. Someday I'll get somebody to take some pictures of the plane in flight and forward them to the list...

    Subject: 8.50x6.00 on 801
    Dave I have 8.50x6.00 tires on my 801. I had problems with flat tires until I modified the rim to accommodate a normal 8.50x6.00 tube. There are not 8.50 tubes that I could find with the 90 degree stem. The manufacture of the rim had a site that showed how and where to drill the hole. I did it 3 years ago so the site may no longer exist. If you need some pics let me know. There is about 1/4" of clearance between the tire and the gear legs. I'm not sure you could go much wider without re-engineering the wheel and brake attachment. Bill Wilcox N801BW Valdez, Alaska 375 hrs From: "Dave Ruddiman" <pacificpainting@comcast.net> Subject: Zenith-List: 801 Tire Clearance 801 People, I haven't started my fuselage yet so I don't know the answer to this question. What is the clearance between the wheels and the gear legs? Both the mains and the nose. I assume 8.50 tires will fit, but I am curious if anything larger will. If anyone knows, I would appreciate knowing too.

    Subject: Re: 701 slats again
    Don't feel alone guys........ I'm building a 601XL but my first build was an Excalibur ( a Challenger-like 2 place UL). We have a builder in Florida who has his Excalibur up for sale for half a year now because he seems to have given up on modifying it into an open class pylon racer. He built the very first clipped-wing Excalibur, progressed through at least three different Gee-Whiz props, each of which was going to turn the little plane into a rocket according to him. He has now ditched the Rotax 503 DCDI engine in favor of a Hirth or HKS with about 20 or so more hp. All this on an airframe which has the drag characteristics of a powered parachute! It is truly amazing how some builders take the latiyudes allowed to us in experimental aircraft to the extremes of trying to make the design into something it was never intended to be. Oh well.... to each his own and may God bless....

    Subject: RE: Alternator Recommendations
    A rule of thumb is if you have a load meter then install loads only up to the capacity of the charging system. Without the load meter only install to 80%. I guess the reverse is true... without a meter and 30A of continuous use ( everything on after starting) the generator/alternator should be capable of producing 36A. Noel -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of Brandon Tucker Sent: Thursday, November 30, 2006 12:00 PM Subject: Zenith-List: RE: Alternator Recommendations I bought a 45 amp internally regulated alternator to install in my HDS Corvair, and sold it after figuring out that there is no way to make it fit under the nosebowl. If you are going with the WW Corvair conversion, the small dynamo is the only thing that will fit. Your only other option is to mount the alt in the back of the motor, which will require a little more work than just buying parts from William and bolting them on. Not too much work, but more... IMHO, load shedding, and possibly going with smaller lights, and LEDs when possible would be easier than engineering your own alternator setup. You can purchase the overvoltage protection unit from Bob. I have it installed in my aircraft. After having a regulator fail in a Citabria, and frying the battery, I like the idea of having built in overvoltage protection. He now also has a low voltage indication BAMM unit now, but I know nothing about it other than what it says on the website. R/ Brandon

I have an 80HP 912 and I sprung for the larger oil cooler which I've installed as directed in front of the muffler can. Now, the oil cooler inlet duct in the cowl is rather small: I see a 3/4" opening at the end of the NACA duct.</DIV> <DIV>Has anyone with a recent R912 install on an HD or XL with the same oil cooler placement have the same issue with a small opening? There see ms to be a real lack of pictures of the install to compare mine against so maybe someone can chime in?&nbsp; My oil temps reach 260F which seems a bit higher than most but I do know that my older engine has an oil te mp probe located on the bottom front oil outlet fitting rather than the newer location at the oil pump housing. I reckon my temps are going to b e higher since the oil temps are read after the oil has gone through the engine just before going into the tank. How much higher? I have no idea but does 30F seems reasonable? More?</DIV> <DIV><BR class=khtml-block-placeholder></DIV> <DIV>Right now I'm waiting to hear back from anyone before I go and do s omething drastic like make the opening bigger cutting the roof of the NA CA duct forward or make up some kind of ducting work to come closer the oil cooler and seal it up somehow.</DIV> <DIV><BR class=khtml-block-placeholder></DIV> <DIV>Thanks in advance!</DIV><BR> <DIV><SPAN class=Apple-style-span style="WORD-SPACING: 0px; FONT: 12 px Verdana; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; W HITE-SPACE: normal; LETTER-SPACING: normal; BORDER-COLLAPSE: separate; b order-spacing: 0px 0px; khtml-text-decorations-in-effect: none; apple-te xt-size-adjust: auto; orphans: 2; widows: 2"> <DIV>Trev Page</DIV> <DIV>C-IDUS 601HD R912</DIV><BR class=Apple-interchange-newline></SPAN ></DIV>I've included a picture of the cowl so you can see what I'm talki ng about on the forum <DIV><BR class=khtml-block-placeholder></DIV> <DIV><BR class=khtml-block-placeholder></DIV><PRE><B><FONT face="cou rier new,courier" color=#000000 size=2> roelectric.com com/"&gt;<A href="http://www.buildersbooks.com/">www.buildersbooks.com </A> kitlog.com homebuilthelp.com <A href="http://www.matronics.com/contribution">www.matronics.com/cont ribution</A> "&gt;<A href="http://www.matronics.com/Navigator?Zenith-List">http://w ww.matronics.com/Navigator?Zenith-List</A> </FONT></B><FONT face="courier new,courier" color=#000000 size=2>< /FONT></PRE><PRE><B><FONT face="courier new,courier" color=#000000 s ize=2> href="http://www.aeroelectric.com"&gt;www.aeroelectric.com</A> href="http://www.buildersbooks.com"&gt;www.buildersbooks.com</A> href="http://www.kitlog.com"&gt;www.kitlog.com</A> href="http://www.homebuilthelp.com"&gt;www.homebuilthelp.com</A> href="http://www.matronics.com/contribution"&gt;http://www.matronics.c om/contribution</A> href="http://www.matronics.com/Navigator?Zenith-List"&gt;http://www.ma tronics.com/Navigator?Zenith-List</A> </FONT></B><FONT face="courier new,courier" color=#000000 size=2>< /FONT></PRE></BLOCKQUOTE></DIV><BR></DIV></DIV><PRE><B><FONT face="cou rier new,courier" color=#000000 size=2> ======================== =========== roelectric.com</A> com/">www.buildersbooks.com</A> kitlog.com</A> homebuilthelp.com</A> www.matronics.com/contribution</A> ======================== =========== ">http://www.matronics.com/Navigator?Zenith-List</A> ======================== =========== </B></FONT></PRE> <pre><b><font size=2 color="#000000" face="courier new,courier"> </b></font></pre></body></html>

I'm curious about the use of a more sophisticated cowl like this, although who knows what supply there might be in the future, given the end of CZAW's production for Zenair.

    I really don't blame you for complaining. Bad enough life has stuck you in Texas, having a slight chill or any other discomfort is far too much to heap on top of such a grave misfortune.

    David, I fought a part of the "cold war" serving my time in the Chicago area, working outdoors most of the time. VERY cold and long winters back then.

    From: "zodieman" <webmaster@upac.ca>
    I spoke to CZAW about the availability and so far they're still more than happy to supply kits and parts for 601s considering the firewall-forward system of their SportCruiser is identical to the 601 system they developed. On another note, I took some detailed measurements of my oil cooler and placement and wouldn't you know it.. they are all perfect according to this article I found: http://www.ch601.org/resources/cooling_systems2.htm Looks like maybe the folks in the Czech republic we're doing their homework! Even though the placement, inlet size and distances are right I still have to make up a plenum of sort to funnel the air into the oil cooler but It's worth a try. I reckon I can whip that up in a few hours of glass work Read this topic online here: http://forums.matronics.com/viewtopic.php?p=78275#78275

    Subject: Re: 601XL - Engine out / Glide Experience
    My primary flight instructor before I got my license in the 70's was a crusty, crabby old ex-Marine flight instructor (I know, once a Marine, always a Marine). It seemed that we spent more time on Emergency procedures than basic flight. He had me learn very steep slips, simulated electrical failures and engine off procedures. One time we flew out to a California desert dry lake and he pulled back the throttle several miles away. This was while I was plotting a new course. He had me follow through and actually land on the lake bed. When I attempted to take off again from a full stop, he pulled back the throttle again at about 500 feet. He then told me that the scratch on the lake bed ahead was a "bunch of bushes" that I had to avoid on landing again. We performed several "forced landings" and "aborted take-offs" that day. On the way back to EMT (El Monte, CA) he pulled back the throttle again over a rural part of town. He gave me power again at about 200 feet over a deserted road. We had three more similar days before I had my final check ride. At the time, I was very irritated with him. Several years later, the two-cycle engine seized in my B1RD ultralight and I had to make a forced landing on a highway center meridian. When the engine quit, I calmly remembered my training and experience and flew the ultralight all the way down to a perfect landing. I was pleasantly surprised at how calm I was during that emergency. There is no better way to prepare yourself for an emergency than practice.

    Subject: Re: Matco Tailwheel install: was Re: N601XT flies... for real
    this time... Mike, The installation was much simpler than the tailwheel from the plans, with the exception of having to weld a little. First, buy leaf spring #4 from here: http://aircraftspruce.com/catalog/lgpages/leafsprings.php I had to weld about a 5" extention to it to get it to reach the forward spring mount bolt. I kept most of the spring cool with a wet rag while welding at the end. The part of the spring that "springs" did not lose any heat treating. I'll try to get a picture of it and send it to you. I bought the solid Matco tailwheel from here: http://aircraftspruce.com/catalog/lgpages/matco_tw.php After flying it today, I think the inflatable wheel would be better. You really feel the rough asphalt with the solid wheel. You then buy the spring kit here: http://aircraftspruce.com/catalog/lgpages/comp_springs.php Installation was less than 2 hours including welding an extension to the spring. It was a very easy upgrade. -Much easier than scratch building the tailwheel the first time... R/ Brandon ---------------------------------
