I had some of those on an ultralight once...and they were marginal, at best. I seem to remember that they "warped"....wouldn't run true....couldn't be balanced properly....just a general headache. The Grove wheels, on the other hand, are excellent....very well made. I recommend them. I know, they're pricey. But like most things, you get what you pay for.

I also have the battery mounted on the firewall. The reason adding weight forward is not much of an option is because of gross weight of 1320. What you add you have to take away. The only option is weight reduction in the rear. Wonder how she would fly with half an elevator ? Just kidding. best regards, Bill -----Original Message----- From: Paul Mulwitz Subject: Re: Zenith-List: 601XL Fuel Tank Capacity --> Zenith-List message posted by: Paul Mulwitz Hi Bill, Thanks for the info. I interpret your comment to mean 11 gallons is the useable fuel in the tank as installed in the plane. I am not at all surprised the usable fuel is not 12 gallons in a 12 gallon tank. There is always some tank space that doesn't translate to gas going to the engine in flight. You may be right about the weight and balance issue introduced by the fuel "Shortage". On the other hand, the fuel tanks are probably placed very near the ideal CG. This is done so the removal of fuel doesn't make a big change in the plane's CG during a long flight. I wouldn't lose sleep over this being a big design flaw until the complete picture is clear with the initial weight and balance calculations on your specific plane. If you need more weight up front you can always put the battery in the engine compartment like it is in most cars. I suspect it is more likely that your plane will need more empty weight in the rear and you will put your battery aft of the seats - just like most small planes. I am sure your plane will be OK. Hang in there.

GPAC does sell a hydraulic set up for the wheels: http://www.greatplainsas.com/schbrakes.html -For that price, you may as well go with the Grove or Matco. I kept mine mechanical and custom built rudder pedals for the brake cables. I agree that the Asuza parts are a bit cheesey. The brake drums are quite thin. I don't know how well they will work, but I will report back when I start taxi tests - hopefully in the next month or so. They use the Asuza in the Sonex, so I would like to think that they should have some working qualities...

I'm new to this list but have followed it for a while. I'm trying to decide if the 601XL is the kit for me and I have a couple questions if you guys could help out, it would be much appreaciated. I know the max weight is listed at 1320 but I was wondering if you could push it to 1450-1500 if you don't do any acrobatics? Second question- what would you need to do(airframe mods) to push the VNE to 200? What I'm getting at is creating a plane that is registered ELSA, but will far exceed the limitations as soon as your away from the airport.

I used a standard countersink mounted in my 14 volt drill to cut the countersinks. I set my calipers (Mitutoyo, but anything will work) to the width of the rivet and kept taking a little metal off at a time until I had reached at least the diameter of the rivet. If the countersink bevel is too narrow you will have to file down some of the rivet after setting to get it flush with the skin. If it is too wide/deep the rivet will spin a little after setting. Either one is OK since there are two rivets per nut plate. For setting I used a one ton arbor press I already had in my shop with a flat plate on the bottom and round bar mounted in the quill. This works incredibly well. My total procedure: 1. Drill pilot holes in the inspection plate. 2. Match drill the holes in the skin using clecos. 3. Enlarge the holes in both inspection plate and skin until big enough for the screws. 4. Remove the inspection plate. 5. Cut the inspection hole in the skin - keep 10 mm distance from center of screw holes. 6. Make a mark parallel to the edge of the inspection plate, thru the screw hole, with at least 1/4 inch on each side of the screw hole. 7. Mark one rivet location on each hole. 8. Drill first rivet hole for each nut plate on drill press. 9. Countersink first rivet location for each nut plate. 10. Set first rivet in each nut plate. Position the nut plate over the screw hole in the inspection plate. 11. Back drill second rivet hole, on the drill press, for each nut plate. The pre-marked line should show through the rivet hole in the nut plate. 12. Countersink second rivet hole for each plate. 13. Set second rivet for each nut plate. It sounds complicated, but it is faster to do than type about.

For the very limeted number of counter sunk holes you have to do you can buy a countersink bit (threaded ou un threaded) from one of the tool companies. For anyone who needs a 120 Degree Countersink, we keep them in stock with pilot sizes #40(3/32), #30(1/8"), #21(5/32"), #10(3/16"), and 1/4". We also of course stock the Countersink "Cages" or Microstops which enable you to achive the perfect countersink cut every time. If you only have a few holes to countersink, and they are not critical, you can also use one of our "chucking spuds" which has a 1/4" chucking shank and 1/4-28 female threads. Simply screw the countersink cutter into the female threads and chuck the 1/4" shank in your regular drill motor and start countersinking. You can find the 120 Degree Cutters and Countersink Cages on our website at www.browntool.com - click on "products" on the opening page and then click on the "countersink cutters & countersink cages" button. The Chucking Spud can be found under the "Misc Tools #2" button. Any questions, need help? Feel free to call us at 1-800-587-3883, we are more than glad to help. Thanks!

The RV 7 will cruise around 200 with a top speed of 210, yet only has a VNE of 230...Never had it reported that it is a problem. I don't think you will get anywhere near 200mph in an Xl. As to max weight the HDS can be flown over gross quite happily, normally it is plated for 1200 but I have flown it at 1300 many times. The airframe is rated to +/-6g ultimate (or 4.5 G with a 1.5 safety factor). Going a little over gross simply means you have less margin. For examply 1200*4.5= 5400lbs....5400/ 1300 (say) = 4.15Gs Your stall speed will go up too. Now how will flying above gross affect the legal situation?...I don't know....But it's a bit like Martha Stewart...Try not to get caught, but if you do you can still be a TV star...No problem!

You need to read up on the regulations for LSA aircraft at the EAA.org website and the FAA regulations themselves. Also I'd recommend that you look through the archives for the Sport Aircraft Forum to learn more about the new rules. When you buy one of the Zenith kits and build the aircraft, you will certify it in the 51% built category, not as an ELSA. For an aircraft to be flown by a Sport Pilot it must conform to many performance limitations. One of them is that the maximum continuous cruise speed must not exceed 138 mph. If the maximum continuous cruise speed is above 138 mph it is not a LSA and cannot be flown by a sport pilot.

I was thinking of plans building a 601XL and subsituting thicker materials to increase the overall strength of the airframe. I was going to use a o-235 for certification purposes, then switch to a o- 320/160hp after the fact( I meant Ex- homebuilt, sorry). Maybe I should just skip it and go with a RV7A/io-390? My last plane was a 180KT twin and you get used to traveling that speed. I'm just trying to figure out how to duplicate that as cheaply as possible. Bruce P.S. I've read all the LSA rules and regs and I understand them. I'm trying to build a multipurpose aircraft that will qualify for sport pilot rules when you only have 10 gal of fuel on board and redline the engine at an artificially low RPM and no luggage. Then when a "reguar pilot is in command, you fill up the tanks, throw the overnight bags in the back, and twist the engine way past redline- say 2800 RPM and cruise 165KTs. I think This will require a ground adjustable prop. ----- Original Message ----- From: jim Subject: Re: Zenith-List: Zenith 601XL Weight & Balance > --> Zenith-List message posted by: "jim" > > Bruce, > > Short answer: You cannot do this. > > You need to read up on the regulations for LSA aircraft at the > EAA.org website and the FAA regulations themselves.

Maybe my normal paranoia is showing, but could Bruce be an investigator trying to interject himself to learn about violations and such? I echo Jim's sentiment and what he said. Further, you have to know that there are a bunch of powerful folks with interests counter to the Light Sport Aircraft rules and experimental aviation in general. All you have to do is think of all the experimental homebuilt aircraft you see at Fun in Sun, ask yourself what if the were Certified Factory aircraft and consider that value to certified GA manufactures and then you see who might not wish us well. What we experimenter do is so special and I am so proud to be associated with such fine fellows as you all that I would never consider risking losing the privileges I have earned. And I will not associate with anyone who will risk it. Bruce, if that is who you really are, take a hike.

The 601XL is a great Sport Pilot qualified plane, purely from posts here, you will never get it to exceed the limits of Sport Pilot without creating something else entirely. You would basically have to redesign from the ground up to get a big enough motor on the front.... So, if flying 200 mph is what you want to do, go with the RV; if flying as a Sport Pilot is what you want to do, go with the XL, or a Sonex, or one of the many other Sport Qualified kits out there. I think maybe a KR might be a fast enough project for you... Living in South Texas, I;m not a big fan of wood projects personally though. - Bruce J.

Raker" Subject: Zenith-List: Wheel Kits --> Zenith-List message posted by: "P.H. Raker" Hi, Kevin, I believe ZAC tried them on one of their early prototypes and found dismal durability. There is a photo of a wheel with the drum brake in my builder's photo guide, with the note that it's the wrone wheel & brake. I seem to recall Nick (or was it Sebastien?) saying that under heavy braking they found that the plastic in the wheels would soften (almost melt). That is definitely not something I want to happen on my plane. I hope you and others don't either. On another note, I believe the Asuza wheels were designed for Part 103 ultralights. It doesn't take much of a wheel/brake combination to stop such a lightweight. Phil Raker N556P HDS/Stratus ~85% completed --> Zenith-List message posted by: "kevinbonds" It will be a while before I'm ready for them but, I started looking at wheel kits tonight. Anyone have any wisdom to share about what to look for. I'm wondering about the AZUSALITE wheels that are made of Zytel Nylon material. They are very light weight. Anyone using them? The kits all seem to come with drum brakes. Is there a disc brake system for these wheels? I checked the archives already and found nothing on alternatives to Matco.

One of the things that serious Pilots and builders agree on is a sense of self-regulated honesty. If you don't have the integrity or the intellect to adhere to these rules, you shouldn't build or buy. You'll kill yourself not knowing fundamentally that an aircraft is a balance of weight and performance to strength. Our insurance rates would go up only because you got the Darwin award. Your comments have been forwarded to manufacturers e-list and the regional FAA safety office so they can evaluate these comments before you submit a request for Airworthiness, write a check to buy or build an aircraft.

I.e set the ground adjustable prop and plate the gross weight such that this is a sport pilot legal airplane, but make a few ajustments to make it fly with the performance of an RV 7. On the face of it to the uninitiated this is a reasonable question. Of course it is not realistic propostion leaglly and technically not feasible with this airplane. In theory you might be able do it with say an RV 7 with Rv9 wings attached and a small engine, even though the final empty weight will be above 1000lbs most likely. Of course to change it back to the fire breathing beast is a lot more work than is reasonable and would require the airplane to be re-registered, if indeed this would even be allowed. Anyway, I just didn't get the sense this was someone intentionally trying to break the rules...

I don't know if the Matco main wheels are built like the nose wheel and I don't know how my nose wheel compares with the current Matco design. The Grove wheels on my plane appear to be of significantly better quality than the Matco nose wheel. The Grove wheels came with tapered roller bearings wile the Matco nose wheel had sealed ball bearings. The opening for the valve stem on the Grove wheels was a half circle cutout on each half of the wheel that allowed the stem to emerge from the center of the wheel. The Matco wheel had a hole though one half of the wheel so the valve stem came out off center. On my nose wheel, the valve stem would not clear the wheel fork as the wheel rotated and the tube would be twisted to one side and it was very difficult to get the valve stem through the hole (the valve stems were brass with a 90 degree bend in them). I ended up putting the two halves of the Matco wheel together and drilling a new valve stem hole on center and plugging the original hole with epoxy. I didn't weigh the wheels but I would guess that the Grove wheels were slightly heavier with the roller bearings and somewhat sturdier construction. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. do not archive. > --> Zenith-List message posted by: "Robin Bellach" <601zv@ritternet.com> > > Do you know how they compare in weight? > ----- Original Message ----- > From: "Bryan Martin" > To: "Zenith List" > Sent: Thursday, December 08, 2005 4:50 AM > Subject: Re: Zenith-List: Wheel Kits > > >> --> Zenith-List message posted by: Bryan Martin > >> >> Grove wheels are an alternative to Matco but they are a bit more money. >> >> >> -- ________________________________ Message 51 ____________________________________ Time: 04:06:40 PM PST US Subject: Re: Zenith-List: Zenith 601XL Weight & Balance From: Bryan Martin --> Zenith-List message posted by: Bryan Martin 1. I don't think you understand the LSA rules as well as you think you do. You can't legally switch an airplane from LSA compliant to non compliant and back, it must be built to the LSA limitations and remain in compliance for it's entire history to remain eligible for LSA status. It's not like an airplane that can be flown in the utility category at one gross weight and flown in the normal category at a higher gross weight. 2. You can't can't legally change engines in an amateur built airplane after certification without informing the FAA and putting the airplane back into phase I testing. I believe you have to test for an additional 5 hours in the new configuration before you can return the plane to normal flight status. Failing to follow this rule will at the very least give your insurance company a valid excuse not to pay your damage claim in the event of an incident. 3. since you would have to build this modified airplane from scratch anyway, why not just build an RV-7 from scratch? It wouldn't cost much more. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. do not archive. > --> Zenith-List message posted by: brucelee@mn.rr.com > > First, I appreciate your response- it is helpful and constructive.

I do find it interesting how some people here get pretty worked up in hurry though. Remember, I have not done anything yet- all I've done is talk about what I would like to do. Don't you think claiming you've reported someone to the thought police is just a little extreme? Enough on that subject- are any of you guys fimiliar with the sonex known as the cleanex? Does anyone know what catagory it is regestered in? the engine weighs only 15lbs more than a 3300Jabaru, but if he twists it 3300RPM, he cruises about 185mph! This in a aircraft that clearly qualifies for LSA if he just keeps the RPM down! Now, I don't expect anyone to put in writing that they are wilfully going to "break the rules" but do you really think nobody is going to push that throttle in just a little more? All I am interested in is a dialog about the possibilities that are out there and how a person can create what they want and what the ramafications of doing that are.

Universal tube marks. --> Zenith-List message posted by: Gary Gower Hi Jon, Yes, has to affect a little. probably more if the front wheel is out of level... Not sure how much affects if the mains are a little out of level, because the filler is in the front high central part of each wing tank... I drained and messured the gasoline when I bought the tube, (got back from a family trip to Disneyland (Los Angeles).., yes I manage to drive one afternoon to Corona ;-) I refilled the tanks with 10 liters at a time (red 2.5 gallon gasoline plastic jug), one jug each tank until got 38 liters just at the base of the filler neck. Noting the reading in the tube for each jug. Since we did the test flight, some gasoline was always sifoned out (the wing had stains with the little dirt it had) when flown with full tanks. So I call it full at 35 liters. (no stains since that full mark) Also, as the tank is not a perfect square box. From the 35 liter mark, I drained first 5 liters and noted it, then 5 more (up to 10) and noted this mark also. This way when the gasoline position is below the 10 liter mark , I can add safely a jug without spiling the gasoline over the wing (or five liters in the case). 10 liters jugs work perfect for me to fill the plane, steping on a two step kitchen ladder. Bigger jugs are too heavy for me and tiresome to hold up in the air until the gasoline gets to a confortable (lighter) level :-) All this is in the card that got with the tube, with the preflight cards. Also I estimated the lph at cruise speed and made a 1, 2, and 3 hour flight time note marks (red pen) in the card. Yes, double checking that BOTH tanks are at the same level, remember that both tanks are interconected in the 701. From this, just aply a little common sense to the timing of your flight and back up with the electric gas level instruments. Just a Comment: Remember to park the plane with the wings as level as possible, for a long time (overnight), this to prevent some of the gasoline to go from the higher tank to the lower and lots of money could drain in the grass :-( Just in case,we installed a little 1/4" gas valves in each hose, safetied open with a little tie grap. to be able ot close the tanks if we park in unlevel in a XCountry flight... Happened to a pilot once a few years ago. Saludos Gary Gower.

What you can be fairly certain is that the DAR probably does, in other words if he see what he thinks is a fast airplane he is almost certainly going to be very interested what exactly you have done to slow it down. I think the Rules state that the airplane has to have a maximum "design" speed of 138mph (I'm by no means and expert on the LSA rules), so I wonder what happens when you have a plane that is clearly designed to go faster but has been modified to slow it down? It would be fun to see the look on a DAR's face as you stand next to a turbine Lanceair 4P with your sport pilot certificate though..:) Frank -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of Bruce Lee Subject: Re: Zenith-List: Zenith 601XL Weight & Balance --> Zenith-List message posted by: "Bruce Lee" I appreciate all of the good input I have recieved on the subject!

At sea level, the cruise speed is 135mph. At 8000ft TAS is 170mph(normal max cruise)- they do not spec rpm(VNE is actually 197mph). Zenith claims 138mph cruise @ 2800 rpm- well below what the engine can comfortably cruise at- you can twist it past 3200 with out much worry. Yet both of these planes are "poster children" for LSA when they are both capable of much higher than legal speed by just pushing in the lever- what gives? All I can think of is everyone is relying on self control by the pilot- yea, right. Another example is the J250 by Jabaru aircraft company- when it's not LSA, it has four seats and goes a whole bunch faster than 138mph. Pull out two seats and limit the rpm and weight and viola! you have a LSA- am I the only person who notices this stuff? I don't think so. Why don't other people want to discuss this?

At sea level, the cruise speed is 135mph. At 8000ft TAS is 170mph(normal max cruise)- they do not spec rpm(VNE is actually 197mph). Zenith claims 138mph cruise @ 2800 rpm- well below what the engine can comfortably cruise at- you can twist it past 3200 with out much worry. Yet both of these planes are "poster children" for LSA when they are both capable of much higher than legal speed by just pushing in the lever- what gives? All I can think of is everyone is relying on self control by the pilot- yea, right. Another example is the J250 by Jabaru aircraft company- when it's not LSA, it has four seats and goes a whole bunch faster than 138mph. Pull out two seats and limit the rpm and weight and viola! you have a LSA- am I the only person who notices this stuff? I don't think so. Why don't other people want to discuss this?

Guys, before you bash the guy every which way, it might be prudent to at least write what he wrote: "My last plane was a 180KT twin and you get used to traveling that speed." Of course, that doesn't mean he's licensed, and maybe he admitted somewhere that he isn't a pilot and I missed it. But geez....how about lightening up a bit? Let the guy do what he wants, and if you choose to give advice, how about something constructive (or if not, then nothing at all?) Are you gonna bash me too because I drove over the speed limit on my way home tonight, and that might cause the government to rescind our rights to drive? This has gotten ridiculous...how about back to homebuilding a Zodiac?

Alas, it is also a bit frustrating for some of us, so give us a little slack. The Sonex is a very similar plane to the Zodiac. It is all metal, uses a similar size engine, and has two seats. I believe it is a lot smaller in the cockpit area and generally a bit faster in cruise speed. While the Sonex people claim it is LSA compatible, that is a subject that might not be agreed upon by the FAA or the insurance companies. It meets the gross weight and stall speed limitations, but the cruise speed may be a bit high. Fortunately for some of us, the cruise speed limit on LSA is very vague. It includes qualifiers about "Maximum Continuous Power" and "Sea Level" which are difficult to nail down when we don't fly at sea level and nobody really knows what "Maximum Continuous Power" really means. I generally believe this is a non-issue for those of us who are flying under Sport Pilot restrictions due to lack of a medical certificate. The issue of maximum gross weight is a horse of a different color. It is very clear what this means, and a plane must have this number specified before it can be issued an airworthiness certificate. It is not something you can change from one flight to the next. If your plane has a maximum gross weight over 1320 pounds it clearly is not compliant with LSA and cannot be flown under Sport Pilot limitations. It is possible, and indeed common, for pilots to fly their planes loaded over gross weight occasionally. They should realize they are violating the limits placed on the plane and may pay the ultimate price for this violation. I would hope they consider the actual weather conditions (particularly density altitude) and their own pilot skills when flying with an overloaded plane. It is much more likely for a plane to stall under this condition and the characteristics of both stalls and normal flight may be considerably different from the normal ones. Other LSA limits which may or may not be met with either a Sonex or Zodiac include fixed pitch or ground adjustable prop. If you install an in-flight adjustable or constant speed prop you are, once again, out of the realm of LSA. This doesn't mean you can't do it. It just means you need a private pilot certificate or better and a medical certificate to fly the plane. I think I speak the thoughts of many listers when I suggest you avoid violating the rules of LSA and SP limitations if you want to fly under the Sport Pilot rule. I think we are all a bit nervous about the new freedom it gives us (particularly those of us who can't easily get a new medical certificate) and we don't want to wave any red flags in front of the FAA bull. If it is your desire to avoid the cost and effort of getting a higher level license than the Sport Pilot certificate, then I urge you to reconsider your goals. I personally think the Sport Pilot certificate is a nice starting place for a new pilot to get to fly but I don't think it is a good ending place for him to stay. I believe the more we know the more likely we will survive the inevitable tense moments that come up from time to time while flying. I personally think training is one of the things we should all continue to do throughout our flying careers. Even if we don't actually get additional ratings and certificates, I think it is wise to continue gaining skills like those needed by commercial pilots and instrument ratings just to have a high likelihood if survival as general aviation pilots in the real world. After all of that, I wish you luck in your airplane building and flying future. I also encourage you to consider anything and discuss anything, but expect harsh reactions if you seem to be planning on intentionally violating the rules. We have a tradition of following the rules in the experimental airplane community, and most of us don't take kindly to other people doing things we feel may endanger our own freedom to exercise our rights to build and fly our planes.

And it has been beaten to death anyway... I will point out a couple of other possible sticking points: >>I was thinking of plans building a 601XL and subsituting thicker >>materials to increase the overall strength of the airframe. Substituting thicker materials to increase the strength of the airframe is not the best approach. It is like fusing a disc in your back. It may relieve stress on that disc, but the surrounding discs will be stressed further. I always get a little concerned when I hear comments like this. >>I was going to use a o-235 for certification purposes, then switch to a o- >>320/160hp after the fact( I meant Ex- homebuilt, sorry). This would obviously qualify as a "major change," requiring paperwork with the FAA. Putting a 150hp engine in the place of 120hp max, at a significant weight penalty is asking for major issues as well. 265# to 290# depending on config is a lot of weight for this aircraft - even if you "thicken" up some parts. It occurred to me that if you can afford an O-320, then you could probably look into some pretty racey aircraft. I say forget the Zenith and build a rocket F1 (See this months Kitplanes). When you get too old and fat and broken to get a medical, sell the rocket and buy two LSA's... -Probably not what you wanted to hear, but it sounds to me you are asking for a sweet wholesome girl who is a devil in bed. I am told she only exists in my dreams. If you find her, let me know...

Been reading the list via the web browser for a couple of months while waiting for my CH701 kit to arrive. Hurricane Katrina held up delivery, was supposed to ship first week October... well, tomorrow the crate is scheduled to arrive, and I'm so excited that I got up the courage to join in here tonight. Got some stick time in a local's 701 in April at an EAA fly-in, liked the way it felt. Ordered the 701 kit with 912 FWF, cabin heat, bubble doors, nav lights and folding wing option. This will be my second kitplane, assembled a Kitfox Lite a couple of years ago and plan to sell it to pay for the 912 when ready for it. Got a taste of tube & fabric, now I'm looking forward to doing all-aluminum construction. This _is_ supposed to be educational, right? You can see a picture of my Kitfox here: Haven't had much to do with sheet metal work since high school metal shop 30 years ago, however, getting good technical advice and mentoring from an experienced A&P for this project. Now for the questions: Firewall forward. Is the Skyshops fwf really that much faster than the ZAC supplied fwf? Stupid me, should have waited, didn't discover the availability of the Skyshops fwf until too late... Does anybody know if ZAC will accept a return of the parts that won't be needed? From the pics, the Skyshops cowl has a much better fit and finish than the ZAC cowl. If it's too big of a deal to return the pieces suppose could sell the ZAC cowl to a scratch builder and buy the retrofit kit. Carb heat & cabin heat with the Skyshops fwf. Can both be done or do you have to choose one or the other? Will a special muffler shroud be needed? Next question. What did you find to be the most difficult task in the assembly process? Slats? What has the most "gotcha's"? That's about it for now, expect I'll be bugging you guys soon enough. Thanks Rory Lacombe, LA - just across the lake from New Orleans do not archive
