    Tim, I don't have much to add to what Jeff already said other than to add a few close-up pictures of mine with the new firewall shelf configuration. I did not measure my degrees of motion, but there is enough to fully actuate the throttle from stop-to-stop with some to spare. Also, the brass cable adjuster going into the carby needs a bend to avoid the nose gear strut. As recommended by Jabiru, I used a tube bender. Just make sure not to make your bend right where the brass transitions from thick wall to thin wall. I will break there if you do. Look down the inside of it to see where it transitions. Good Luck, -------- David Gallagher 601 XL, tail &amp; wings completed and fueslage pretty well done. Working engine and electrical systems.

    While the target is clearly "hired gun" builders and complex aircraft requiring a lot of factory assistance, there could be much wider impact. While industry reps and EAA are against it, the FAA wants to get rid of "shared credit" when determining who built the majority of the aircraft. Without this shared credit, The CH640 QB kit I built would not give me enough credit to have built 51% of the aircraft using the current checklist. I don't know for sure about other kits but I doubt most QB kits would be safe under the proposal. In essence this would change the current standard that basically says if you do one task, say fabricate a rib, you get full credit for that task; to one where if the factory does a portion of a task, say fabricate one rib, they get full credit for the task and the builder gets 0 even if they fabricated every other rib. I would be cautious about thinking the proposed changes won't effect us. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=164778#164778

    Subject: Torque of 3/16" or An3 Bolts
    Zenith Listers, do not archive I have been following the "Bolt Torque" subject with interest. It has been my experience ( for a little over 51 years now ) that folks with limited experience tend to "over torque" those little 3/16" diameter ( AN3 ) bolts which are used through-out our airplanes. You know - if tight is good, tighter is better! I've seen others just wring them "right off". The worst situation is the "over tightened" bolt that hasn't sheared "YET", especially if it is in a critical location. Of course a properly calibrated torque wrench of the correct size is the proper way to go, but I must admit this old mechanic doesn't alway use one. Many times, the particular installation will have the very definite specified torque for the particular bolt called out in the manual or instructions being used, such as gearbox or engine buildup. However, most bolts will be "torqued/tightened" using just industry standards, such as in AC 43.13-1. Of course there will be those "special" installations such as the Zenith rudder pedal bearing support installation being discussed. Probably, the best case here would be that the "kit supplier" specify what to do in these "special" situations. ( One may be a "hinge" where rotational movement is involved - here we usually use a castleated nut. ) However, I suspect that this will not be the norm with "most" kit suppliers. Just sometimes, we must do a little thinking for ourselves. If the rudder "torque tube" must rotate in the bearing support, we should give it some thought on our own. If in doubt, seek the guidance of a experienced mechanic or builder or even better the experts at the kit supplier, such as Roger or Nick at Zenith. If you are fairly new at this, I suggest you get a proper torque wrench and some 3/16' bolts and NEW fiber lock nuts ( since that is what we use the most of, except in the engine compartment in some places ) and practice torqeing some of those bolts. I think you'll br surprised how little effort it takes. One final suggestion: use just a 1/4" drive wratchet rather than a 3/8" drive wratchet when installing 3/16" diameter bolts using self locking nuts, IF you are not using a calibrated torque wrench. You will tend to over torque or stretch those little bolts with that "big" 3/8 drive ratchet. Practice makes perfect! Jim Hoak - 601 HD

    I am installing new tires on the main gear and wondering the best way to do this? Do I have to remove the brake housing first? It looks like the nuts & bolts holding the brake housing on is going to be difficult to get to with a wrench. Thanks for any suggestions.

    Subject: 601XL QB Flaps problems
    Hi All, I did a test fit of wings on my 601 XL QB this weekend and have some problems with the flaps. 1. The slot in the end rib of the flaps seems to have been cut at the wrong location. According to my plans it should be 40mm from the top and 80 mm from the side of the rib. On my flaps both slots are centered on 90 mm from the edge of the rib. Of course with this the flap doesn't fit well when engaged with the flap torque tube. I checked the dimensions on the torque tube ends and they do match the plans. 2. It also seems like the flap hinge that fits into the wing skin was drilled a bit too far to the inboard sides by approx 1/16 of an inch or so. As a result the edge of the flap sticks out a bit beyond the edge of the wing and it hits the flap torque tube. Anyone else have these problems with their QB flaps ? I suspect the factory in Columbia just test fit the flaps without the torque tubes and it fit fine then but it seems like both items are done wrong ? Thanks, John Davis Burnsville, NC 601 XL - QB - Jabiru 3300

    Subject: Panel text colors?
    I am going to paint my panel/console with a dark grey textured paint (Rustoleum MultiColor Textured). I have checked, and Brother tape labels will adhere to it acceptably. My question is whether to use white-on-black text or black-on-white text. I know that most engraved placards are white-on-black, but was wondering if there is any "preferred" or "most visible to aging eyes" choice. I do fly at night and have good instrument lighting, but am currently planning no direct panel lighting. Maybe some NASA report or FAA test?

    Subject: Best STOL 701 video ever!!!
    I just viewed a new back-country flying DVD prepared by Christopher Desmond with flights by him and Michael Heintz (Chris Heintz's son). Christopher is a 701 pilot and a member of our N. California flying club. This DVD is really great! The photography and the STOL flying far exceed anything I have ever seen; Hollywood couldn't do better! Cameras were mounted on the wing, inside the cockpit, and looking up from the ground. Flights go into canyons, land on river banks, and fly from small gravel and grass strips. This video is truly spectacular. No, I'm not selling anything, nor do I have any financial interest in this video, but I recommend that, if you are interested in back country STOL flying, look at a preview of this DVD on YouTube at <http://www.youtube.com/watch?v=DbBb_IuT1_o> http://www.youtube.com/watch?v=DbBb_IuT1_o or contact Christopher to order the full DVD at <http://www.stol-adventures.com/> http://www.stol-adventures.com/. Regards, Les ..... with 15 very satisfied hours on my CH701, N67MG

    Hi Jack, You should be able to jack the fork and take the pressure off the axle. Then remove the axle and spacers, which will allow you to let the rotor down from between the brake pads. Then the disassembly is little more than letting out the air and splitting the wheel for removal and replacement of the tube and tire. I've included a drawing and pics of a device that makes that task a bit easier for you. http://www.macsmachine.com/images/wheelfairings/full/fairingbrakefit.gif http://www.macsmachine.com/images/gear/full/brakes2forks.gif http://www.macsmachine.com/images/completion/full/601-gear-fork-jack.gif http://www.macsmachine.com/images/completion/full/Teebarforkjack2.gif Good luck, Larry McFarland 601HDS at www.macsmachine.com jackandval wrote: > > I am installing new tires on the main gear and wondering the best way to do this? > Do I have to remove the brake housing first?

    Subject: Re: Panel text colors?
    Greetings Andrew, I have no scientific evidence. In my experience light on a dark background is easier to read in low light conditions. Also note that interstate signs are white on a dark background. I assume that decision was not arbitrarily. Just another data point. I plan to use a matte grey for my instrument panel and the top of the nose of the aircraft. My lettering will be white on clear tape. I was wondering why you chose textured rather than just a matte finish. Is there a visibility advantage?

John Davis <johnd@data-tech.com> wrote: Hi All, I did a test fit of wings on my 601 XL QB this weekend and have some problems with the flaps. 1. The slot in the end rib of the flaps seems to have been cut at the wrong location. According to my plans it should be 40mm from the top and 80 mm from the side of the rib. On my flaps both slots are centered on 90 mm from the edge of the rib. Of course with this the flap doesn't fit well when engaged with the flap torque tube. I checked the dimensions on the torque tube ends and they do match the plans. 2. It also seems like the flap hinge that fits into the wing skin was drilled a bit too far to the inboard sides by approx 1/16 of an inch or so. As a result the edge of the flap sticks out a bit beyond the edge of the wing and it hits the flap torque tube. Anyone else have these problems with their QB flaps ? I suspect the factory in Columbia just test fit the flaps without the torque tubes and it fit fine then but it seems like both items are done wrong ?

    Subject: Black crud in gascolator
    At 8 hours TT and now again at 15 hours, I noticed a lot of small non-magnetic black particle specks in fuel drained from the gascolator and tank drains on my new 701. These particles settle to the bottom of the drained fuel and stop coming out after draining about 6 ounces. My 701 has only one gascolator that is placed in the fuel line on the engine side of the firewall just downstream of two fuel filters (one for each wing tank). I don't understand how the gascolator could get dirty downstream of the filters and don't know where the specs are coming from. I cleaned everything with a vacuum cleaner and with compressed air pressure before connecting the lines. The black specs are non-metallic and I don't think they are aluminum. My fuel lines are Aeroquip, stainless steel clad, top-of-the-line, and the fuel filters are 10 micron stainless screens that are about 1' in diameter. So far there has been no decrease in fuel flow or engine power. Has anyone else had this problem and there something I should be doing about it besides checking the fuel filters? Thanks for the help, Les

    Regarding removable or folding wings: I asked a rep at Glassair about the folding wing of the Glastar. "Do I have to drain the tanks before wing fold?" His answer was that you could fold with the full 25 gal in each wing and was often trailered at 70MPH. Regarding aileron linkage: I once saw a sailplane with a quick disconnect aileron linkage. It was basically two bell cranks that butted up to each other when assembled for flight. They met with a kind of nylon padded ball and cup arrangement on each end like your thigh bone connects to your hip bone. Just ideas that have been tried.

    Subject: Re: The crud!
    do not archive This probaby does not apply, but....... Several years ago a fellow bought two new gas cans specifically to carry gas from the airport to his private grass strip. Turns out the cans had some sort of coating inside. Never did know if it was paint or something else. Fuel "looked" okay as he was pouring it into the airplane, but after even a short flight he could get crud from the drains. He got the cans at a "farm store" so I'm not sure they were actually "gasoline" cans. So much for that story. Also, since "crud" is more dense (heavier) than fuel, you might take a look at the inside of the hose from the gascolator to the engine. It might be coming apart/melting from within and falling down and into the gascolator! Regards, Zed/701/R912/90+%/90% left

    Eureka! I now have a seat at the table. Got my plans for the 601xl on valentines day of all things. After reading through the plans a few times I see a few things that my detailed orientated brain needs to know. Can anyone detail the crimps on the tail and wing nose ribs? I have seen a few people use routers to cut them but leave out the little detail of type of bit used, etc. They appear to be 12mm across and about that deep. Also, with all the brake plans that I have seen, everyone seems so focused on all the 1/8" radius bends the on the 601. Has anyone considered the 1/4" radius bends that are required? There are far fewer 1/4" radius bends, but they are there. What modifications to a brake are required to change the radius. I'm sure a solution will present itself.

    From: "leinad" <leinad@hughes.net>
    To make crimps on my form blocks I used a rotary rasp in a drill motor. The one I used was about 3/4" at the wide end then tapers to almost a point. It makes very nice tapered crimps. I think I purchased it at Sears. Most of the 1/4 inch radius are on thicker material that I bend over a wooden form in my vice with a mallet. I use a good hard wood, like maple to make these forms. I first cut the edge away so that it is sharper than a 90, more like 70 degrees to take care of spring back, and round the edge with a rasp and sand paper until I've got the radius I want. Check out the tools link on my web sight. http:\daniel.dempseyfamily.us I also use a wooden bending brake, but that's another story.

    Lee Folks like us (people who come up with these wild ideas like building our own airplane) tend to want to obsess over the details. We want to have everything figured out immediately. But remember, this thing is going to be built one part at a time. Just get busy working on a part. You' ll find a solution to the unknowns in due time. There is nothing on this plane you wont be able to accomplish if you just get busy on it. I didn't bother putting the crimp reliefs in my blocks. Tried it, Didn't need them. Some like them but, you'll have to finish the bend a little by hand, no matter what, so I didn't bother. Your results may vary. I put a page on my site for new builders here http://home.comcast.net/~kevinbonds/new_builders.htm Not that I'm an expert or anything. But, I thought it might serve as a reminder to not obsess. I am notorious about obsessing and taking too long to do something. I have been making a conscious effort, lately, to change this detail about myself.

Make the shims longer than the part top be bent and tape the stack to the brake nose to the side of the actual part edges. Eureka! I now have a seat at the table.

    Les, Double-check the Aeroquip specs to see if it is recommended for autofuel (and its alcohol, toluene, etc.). I found that some of the aviation fuel line prohibits autofuel, might be worth checking. That would mean the black specs are decomposing fuel line material, but I don't know if that makes any sense.

    Subject: 601 HDS Project for Sale
    Group, It has been over 1 year since I touched my project. I have been blaming it on my pre-occupation with remodeling the house, but last week it hit me.. I'M BUILDING THE WRONG AIRPLANE!! That's right. The plans say "601", the receipts say "Zenith"..but my dreams say, "Pietenpol." That's been my dream since I saw my first one in 1972! Anyhow, I would like to sell the completed rudder, tail kit, wings and uncompleted center section. The rudder, tail and wings were all purchased kits, but the center section is a scratch build. The wings are for an HDS, with lockers and locker tanks. I don't think I will get all my money out of it, so I will be happy to discuss pricing with any interested parties - all, or part. Gary Boothe Cool, CA 601 HDSTD, WW Conversion 90% done, Tail done, wings done, working on c-section

    Subject: Re: 701 motor mount attach points on firewall
    Jerry, Print 7-E-1 shows a total of 5 attachment points to the firewall, 1 centered up top, 2 mid outboard and 2 lower outboard. Assuming your installing a 912 could you not just use the dimensions used on 7-E-1 to locate the mid outboard attachment points, the dimensions agree with 7-F-7?

    Subject: Re: Sabrina Re: pitching the H-stab
    Hi all, With all the talk of pitching the horizontal stabilizer lately I have a quick question. I am doing my conditional inspection on my 701 and decided to replace the front horizontal stabilizer brackets to the .063 material. There were no cracks in my old ones but I figured I might as well bite the bullet now while the weather is keeping me from flying anyway. I have always felt that I was flying in a nose high attitude while at cruise and that I do not see the higher MPH that others see. I purchased a digital level and have discovered that my horizontal stabilizer was about a half of a degree low in the front (approx 3 mm). I plan on raising it one degree so that I will be a half of a degree higher in the front based on the A-E line. I am wondering if this is a good idea as I believe this will get me flying in a better attitude at cruise and pick up some speed. Any thoughts?

Eastern Standard Time, chicago2paris@msn.com writes: --> Zenith-List message posted by: "Sabrina" <chicago2paris@msn.com> Zenith Aircraft indicated it was a "good idea." I can't imagine that they would say so without calling up Chris in France. So too, the math seems to work out, but more importantly, people have done it and proved it. (Bryan, Scott and several others.) I personally would not go to 3 degrees. The AMDs appear to be about 1 degree down, but they will not confirm that. The problem may be that some actually have the stab pitched slightly up, and that is in fact more dangerous than pitching it slightly down with a nose heavy aircraft. Cessna has proven than tail down force on slow aircraft is an acceptable design. W&B on a 601 is critical. One must always start with an accurate weight and balance sheet (in other words, don't use bathroom scales.)
