      that came with the kit. I am still looking (dreaming) into putting the Dynon
      EFIS onto the panel if I can afford it. If I go that way I will need a new
      tube  for the Angle of A stuff will I not?  
      
      so should I wait till I have made up my mind or will the new size tube fit over
      the old Zenith tube holes??? I would hate to have to patch my new bottom wing
      skin before first flight.

Hi Chris I have an LRI rather than the Dynon pitot tube, but I would guess the hose requirements are similar. I have two hoses that run from the LRI into the fuselage. I mounted both the LRI probe and pitot tube on inspection plates so they don't get broken while moving the wing around. If you do this, you can probably run new tubes later.

Hello Lind, Aviation handhelds are the better choice when it comes to ruggedness and reliability. I would nevertheless recommend to check out pocketfms for PDA/GPS combos. It is a powerful moving map navigation solution with a VERY dedicated commmunty. A number of volunteers maintain the data of every country. Norways airspace structure is fully covered and maintained AFAIK. The software and moving map data is for free (!) Donors of more than 50 Euros/60 $ get conveniant zip files and additional weather data . Check out www.pocketfms.com to alex: Schickes Cockpit, D-M... oder D-E...?

Actually Jon it does matter. Especially the leveling of the aircraft along the A-E reference line ( I stand corrected Bob). This is because of the wing dihedral. If the wing had no dihedral there would be no need to level along A-E. Try this explanation, on your plane with wings and struts installed, string a line from wingtip to wingtip at the rivet line. Get on a ladder and look down from above at the string and rivet line relationship. Notice, that as you move your eye a little forward, then rearward, that you can make the string line appear as if it is not in line with the rivet line. It will look like the wings are either swept forward or swept aft. The dihedral causes this effect. Alternatively, you could drop the tail of the plane by blocking up the nose wheel and view your string line/rivet line. I'll bet it looks like your wings are swept back! N.B. If it looks like the rivet line IS in line with the rivet line, then your eye is not exactly 90 degrees over the string line, or your wings are in fact NOT perfectly aligned. Any way, back to the point, if you were setting the wing incidence in this condition (tail low) you would move the wing tips forward until the string line and rivets were aligned and then drill the aft mounting holes IN THE WRONG LOCATION. So............ in order to set the wing incidence in the fore and aft dimension (i.e. neither swept forward on backward) you must level the aircraft along A-E and view the string/rivet line relationship from EXACTLY above the string (90 degrees).

My second faux pas. I was near the end of the elevator build, and I couldn't find the horn doubler 6T3-6. I went back through my entire inventory to track it down, to no avail. I did have the "L" bracket _leftover_ from that part of the kit. After examing the plans in greater detail, I realized what I did. I don't know it it was just too late, or I was relying on the photo assembly reference too much, but it seems that I cut up 6T3-6, as the "L" bracket for 6T3-2.

Steve, David, and all, I appreciate your input on this... I do understand the error in visual preception that occurs when you are not viewing the rivet line at exactly 90 degrees from above... This is why I will still suggest that the best way (for me, anyway.. and I respect others' way of dealing with this) is to NOT level the plane in any direction but rather use a measuring tape, which is not affected by parallax errors or trying to determine an exact 90 degree observation vantage (because you WILL be on a ladder trying to attempt this observation). The measurement of a point on both wing tips to a common point on the fuselage will determine with great accuracy the proper alignment of the wings. No guessing here.. I agree wholeheartly with Steve about viewing the rivet line and seeing it move when you start lifting the wings.. or moving your head to the left or right....that is precisely why I don't like to to make judgements from what I see when the angle of sight is so critical. I start by leveling each wing to each other (not the ground!) and then adjust each wing to match (to the millimeter using a tape) from that far point on the fuselage near the tail to each wing tip. When this is done (and use a helper to confirm accuracy), drill the tabs. Of course, watch your edge distances... Your last detail is to raise both wings to the specs in the plans.. which, again have no basis on level to earth, rather they are measured with a ruler to points between the fuse and wings. Nothing wrong with eyeballing things for confirmation and comfort, but I rather use a ruler to make the final adjustments. I do NOT have the final word on this, but am simply expressing my understanding of what is in my head at this time. I look forward to more discussion on this if you think I have it wrong. Sometimes, what works best for each of us may be different -- and thats OK !

Chris, The Dynon Pitot probe replaces the standard Zenith dynamic probe. It acts as an aoa probe as well. You will have to run a third line for static pressure, for a total of 3. I placed my static port in the aft fuselage, but that is builder preference. I mounted the probe under the baggage locker, allowing for easy access, and delayed installation. I cut the holes and fabricated the mounts, but did not rivet into place until the wings were mounted for the last time. Having a probe hanging down makes it a real pain in the ass to transport. -More so than you might think... VR/ Brandon Don't pick lemons. See all the new 2007 cars at Yahoo!

Hi Andy, Its been a while since I did that one, but here is what I think I would do now. First, stop drill the inside corners with something like a 1/4" drill. Then I would use a fairly large step drill - perhaps 3/4" or 7/8" to make a starting point for the shears. I would drill this in the waste material perhaps 1" from the final cut line. Then it is a matter of cutting with the shears. The first cuts would leave about 1/4" to the final cut line, and then I would work my way closer to the final line until I was there. Perhaps the last few thousandths in some areas would be done with a file rather than the shears. Clean up the edges with a smooth file and it is done.

It has the standard 6 pack of flight instruments with yellow tag gyros, the DG has autopilot coupling, electric turn & bank, 2 trim indicators, compass, suction, Westech engine instruments, Jabiru style rpm with hour meter new, circut breakers, adjustable air inlet controls, intercom, King KX 170A backup nav-com with head, Narco transponder, Artex 110-4 ELT, Sigtronics headset like new, master switches, gyro's plumbed with filters, encoder, Painted and labled panel in very light grey. All mounting holes countersunk. I will take your blank panel in trade. If anyone is interested, please contact me offline at backstagelive(at)gmail.com or call me at 920-237-1450.

Subject: Re: Cutting out trim tab?
I did like Paul except that I drilled a #20 hole at each corner rather than a 1/4" hole. Then I also use a good new hacksaw to cut about 3/8" inside the cut line at the trailing edge on both sides. That makes it much easier to cut around the trailing edge with the snips. Like Paul described, I used a large step drill inside the waste area to get started with the shears..... first cut about 1/4" inside the line, then a final cut to "save the line". Final finish with file and emory cloth. Ed Moody II ________________________________________________________________________________

all, the other option that works just as well, is AMD's design of a trim tab which does not require a cut. The tab runs from inboard edge to entire length of the port elevator. by 3 inches wide. It is secured by the paino hinge, and is frankly a lot easier. I put in the orignal cut in one, then found the AMD option. I would recommend the later.

I see on the blueprints that Zenith calls for 20 degrees one way and 40 degrees the other for the trim on the 601 XL. How is that measured? How I have it now, there is exactly the same travel up and down from neutral, and neutral is dead center. Is there supposed to be more travel one way over the other?

Another thing I forgot to mention is that if you do cover/close up the gaps at the trailing edges as I did, I think it is a good idea to drill a small #40 or #30 hole to allow the assembly to drip out moisture or "breathe". The hole is way too small for critters to intrude but large enough to drip out.

Only my humble opinion, but the drain holes should be at least 1/4 inch. Smaller than that blocks too easily. With the drill still in the hole, it should also be sloped (pulled) backward when not rotating, enough that it forms a slight negative pressure zone at the hole to suck any water out. I agree - you don't want critters in there!

The unit that is no longer on the list is the GPS that I ended up buying and that is the AvMap Geo Pilot (Sportys item # 1932A). I realize that it does not have many of the features that the high end units have, like weather display and such, but for the money ($795) it has one of the largest displays available and I found it very easy to operate.

Scott, I was planning to use large numbers on the fuselage sides for the following reason. The sides are flat ALMOST. My plans called for the .016 side skins, and didn't know thicker skins were an option until I was past that phase of construction, and the "flat" sides don't look flat. Painting BIG numbers on the side is one idea I have to obscure the imperfection.

Actually the XL may be the worse choice in terms of future parts availability. That is because the XL is still evolving. I can't order many parts for my vintage 2000 XL kit from Zenith because the plans have changes. The instrument panel has moved, the bulkheads have changed shape, etc. That is why lately I've been acting more like a scratch builder than a kit builder. -- Craig ________________________________________________________________________________

Subject: 601XL Wing Flutter
Dear Thread Friends, I went flying this afternoon. Took a fellow with me and just wanted an hour in the clear blue. Conditions were perfect, clear, cool and only a slight wind. The only big thing around much to see nearby is Lake Juliette which has a big coal fired power station in the middle. Three huge steam towers that look like a nuclear power station. We flew around the lake about two miles away at 5000 feet so my pal could get a good look see. On the down wind side we flew into an invisible killer. We were doing above 140 when we flew into it. Instantly the left wing fluttered at a fast pitch, aileron and all and it looked to be moving maybe two inched up and down. I figured a couple seconds would break it off. I didn't have time to look around the passenger to see if the right wing was fluttering, but I suspect it was. I chopped power and did a hard diving wing over to the left and out of it. The flutter sound was great even over my Lightspeed AN system and the whole thing probably last maybe 5 or 6 seconds. I regained control out of the snap dive, maxing above 170 and flew slow and easy back to the field before I tested the controls. Everything felt okay and I could see no wrinkles in the top skin so I landed. Didn't really have much choice. Upon inspection I found no sign of stress, no skin deform, no paint cracked around rivets, nothing. I will take off all inspection panels for a close inspection this weekend and check bolts, controls, etc., but I cannot believe such a prolonged violent movement of the wing did not damage something other than my pride. Two things learned. Don't fly anywhere near a power station. Even at 5000 feet and miles away the invisible heat rises and is most extreme. Maybe intensified in cold weather. The other thing is the XL is very, very tough. Oh, there is a third thing. How could I have been so stupid not to know the first thing !! I am interested though in knowing why the wings fluttered in this thermal? What theory of air dynamics would cause this extreme reaction? Was is just the level of heat and speed the invisible air was streaming past? This was my 90th flight in her and she made me proud again.

Hey Bill, Sounds scary! Glad you are OK. Although it was years ago ( first off I'm NOT a trained test pilot ) I was involved in some actual flutter problems involving a Midget Mustang I built by a friend and latter did flutter tests in a Mustang II built by another friend. When we experienced the flutter with the MM I ( at about 180 mph ) we consulted an old friend who knew Dave Long ( the designer of the MM I ) and picked his brain. One thing he said is if you experience flutter you have mere seconds to SLOW DOWN and the best way to do that is to reduce power and pull the airplane up ( I noticed you dove and increased speed but got out of it ). This procedure helped us with the MM I. What we found with this airplane was an accumulation of built in slop in the aileron control system. This system was all push rods and bellcranks and the builder had just drilled all the holes ( did not ream ) and used AN Standard bolts. I found this quickly by haveing the builder grasp one aileron while I moved the other aileron up and down better than a 1/4" at the trailing edge. Remeber this is a 200 mph plus airplane. We went to NAS and oversized bolts and tightened up the slop. This DIDN'T cure the flutter though. What we found then was that when he filled the counterweight tubes that were mounted forward of the hinge line with lead, he didn't get the tubes full as the lead solidified as he poured it in and left many air spaces inside the tube. We corrected that and the flutter problem went away. Probably both problems contributed to the flutter. In the Mustang II we were doing flutter test in the 225 230 mph range by increasing the speed by 1 mph increments and never had a problem, but we were ready to slow it down if one did arise. I know John from AMD tested for flutter when he did your test flight and he said nothing about it when he landed. You might call him and ask what max speed he uses when testing. Not being an aerodynamicist ( spelling? ) I don't know the cause for your encounter but just maybe it has something to do with the fact that we don't use balanced controls on these Zenith airplanes and a weird air pattern that you encountered because of the heat from the power plant. I've flown over large fires on the ground, as I'm sure you and others have in the past and experienced some pretty rough air but not FLUTTER. In your case, if it was unbalanced controls, it seems that when you dove to 170, it should have made it worse. Do the "grab one aileron and try to move the other test" and see what you find. Otherwise, DON'T fly near the power plant any more! I've been tempted to fly over to that same place but since 9-11 I stay away from all power plants. Let me know if I can help and also what you find.

Took a fellow with me and just wanted an hour in the clear blue. Conditions were perfect, clear, cool and only a slight wind. The only big thing around much to see nearby is Lake Juliette which has a big coal fired power station in the middle. Three huge steam towers that look like a nuclear power station. We flew around the lake about two miles away at 5000 feet so my pal could get a good look see. On the down wind side we flew into an invisible killer. We were doing above 140 when we flew into it. Instantly the left wing fluttered at a fast pitch, aileron and all and it looked to be moving maybe two inched up and down. I figured a couple seconds would break it off. I didn't have time to look around the passenger to see if the right wing was fluttering, but I suspect it was. I chopped power and did a hard diving wing over to the left and out of it. The flutter sound was great even over my Lightspeed AN system and the whole thing probably last maybe 5 or 6 seconds. I regained control out of the snap dive, maxing above 170 and flew slow and easy back to the field before I tested the controls. Everything felt okay and I could see no wrinkles in the top skin so I landed. Didn't really have much choice. Upon inspection I found no sign of stress, no skin deform, no paint cracked around rivets, nothing. I will take off all inspection panels for a close inspection this weekend and check bolts, controls, etc., but I cannot believe such a prolonged violent movement of the wing did not damage something other than my pride. Two things learned. Don't fly anywhere near a power station. Even at 5000 feet and miles away the invisible heat rises and is most extreme. Maybe intensified in cold weather. The other thing is the XL is very, very tough. Oh, there is a third thing. How could I have been so stupid not to know the first thing !! I am interested though in knowing why the wings fluttered in this thermal? What theory of air dynamics would cause this extreme reaction?

Ron- The HD/HDS design has three major advantages, all related to the size of the wings. 1. You can get by with a smaller workspace. 2. If you're scratchbuilding, you don't have to buy so many 12' sheets of stock. 3. 8' brakes are hard enough to come by, 12' even harder. Both XL and HDS prints/manuals have serious problems in my estimation, but "Shooting out prints" and "Writing work instructions" is what I do for a living. You have to balance personal expectations. Listers who have the same job responsibilites as I do can't believe how sloppy the prints and instructions are. On the other hand, how do Zenith instructions stack up to the competition? I don't know- the HDS is the only plane I've attempted to build. Zenith has never failed to be able to supply a replacement part for my HDS, and for that I'm grateful. Two cautions: 1. The Zenith website parts list is out of date. Prepare to receive a quote and pay more than is listed. 2. Make absolutely sure the part number you order is what you need. Bottom line is, CH never had a bad design. Execution is a different story.

Subject: NOT wing flutter!
Date: Jan 27, 2007
(long post) Whoa! One needs be careful saying "wing flutter" on a list devoted to aircraft! In the aerospace world, flutter is a specific phenomenon defined as "dynamic instability of an elastic body in an airstream" (from Aeroelasticity - Bisplinghoff, Ashley and Hoffman - the standard reference text). In a wing-type body, there is a speed *above* which the oscillations of the wing can go unstable, that is, they get bigger and bigger with each cycle. The only solution for this is to either slow down, change the wing's aerodynamic characteristics, for example by deploying spoilers or other controls, or change the wing's structural characteristics, for example by buckling stuff. If you are below that speed, the wing can not flutter. It can shake, rattle and roll for sure, but not flutter! 140 indicated is about 150 true, which should give you plenty of margin. (I am assuming mph. If you were going 140 knots indicated at 5000', that's over 170 mph true, and it's a different story.) Since you sped up and the wing did not come off, what you saw was not flutter, but simply some excitation of the wing bending. A two inch oscillation on a 601-length wing is not even close to being a structural problem. The wing is stressed for +/- 6 G's meaning that it can hold 6 times the gross weight of the aircraft without any failure. This is tested in production aircraft by loading up the wing with distributed sand bag weights, so in a typical 601, that would be about 5000 lbs of sand on each wing. You can bet that it will deflect a lot more than 2 inches! Of course, it is possible to get flutter of just a control surface. This is more likely in aircraft like a 601, which does not have mass balanced ailerons or elevators. But again, since you sped up and this did not get worse, it is very unlikely to have happened. There are a number of scenarios which could lead to an oscillation like you described, excited by the turbulence - including a low frequency control surface vibration linked through the aileron controls to your hand (the soft servo), a vibration caused by a structural change like a loosening cable or control arm, feedback or other failures in the aileron trim system, feedback in the autopilot if you have one (which should be designed to kick off in that situation). You should certainly check all those things and the wing attach bolts, and whatever else you can! But it could just have been the wing and/or aileron vibrating after being excited by the strong turbulence, like a guitar string being strummed. Note - when you encounter airframe vibrations, a good response is always to make small control movements and *slow down*, instead of speeding up.

Date: Jan 27, 2007
Hi Bill,Glad everything came out OK. Looks like you ran into some really weird turbulence from the power-plant, giving you an "E" ticket ride. If you were really experiencing wing or control surface flutter, your diving and picking up speed should have exacerbated the problem with the amplitude going divergent very rapidly, until something(s) bends or more likely breaks off. Only saw this once in a film of a dynamic model in a wind tunnel - once flutter started the entire model was gonzo in a second or two. Do you recall experiencing any feed back in the stick/rudder?In 199 hours in my XL, I have had some bumpy rides and the airplane has handled it ok - just glad I always have my seat belt tight. I have also had some GREAT*, almost I would have believed, GOOD*, landings and I agree the airplane is tough. *GREAT Landing - Airplane is still flyable. GOOD Landing - You can walk away from the airplane.Please let us know if you find anything after your in-depth inspection. I kind of suspect you will not find anything amiss, but if you do it would be a good data point for all of us for tailoring our structural inspections.

It looks like I am wrong. The instrument panel has not moved. 6B14 dated 04/01 and 03/05 show 475 from the base of the instrument panel 6B12-4 to the firewall. But the dimensions of the forward top skin have changed. On 6C1 dated 10/06 6C1-4 is 570 by 1135. But the 05/01 plans show it as 600 by 1300. But the shorter dimension controls the firewall overhang and is trimmed to fit the cowl. 6B15 does show that the position of the most forward vertical stiffing L angle has moved by 45mm. The sheet dated 04/01 shows the stiffener 400 back from the firewall. The sheet dated 07/05 shows 355.

Subject: Does your front bungee cord pin touch the front gear leg?
Date: Jan 27, 2007
Looking over my third-hand 601XL kit I see that the front bungee cord pin 6G2-2 rubs on the gear leg 6G1-1. Looking at the stack-up of dimensions the tolerances are very tight. The 5/8th inch (15.8mm) pin passes through a hole whose center is 25mm from the firewall (see 6B8-7). So the forward edge of the pin is 25 + 15.8/2 = 32.9mm from the firewall. The 2 inch gear leg (radius = 25.4mm) passes through a hole in 6B7-1 that is 60mm from the firewall bend radius. The dimensions in the bottom bearing 6G2-1 are similar: the center of the 2 inch hole is 58mm from the rear edge of the block. So the rear edge of the gear leg is at 60 - 25.4 or 34.6mm from the firewall with some slop for the bend radius. 34.6 - 32.9 gives a clearance of 1.7mm. And the bungee pulls these two pieces together, removing any slop. Does the pin touch the leg on your plane? Is it acceptable to shift the nylon bearing forward to create enough clearance (I've got to replace mine due to other problems)? I'll be asking Zenith the same question. -- Craig ________________________________________________________________________________

I know there are a few guys that fly through Lakeview, Oregon and stop by KLKV for fuel. Marty Turman has been there for years and there are many pilots that speak of him. I am sorry to say that Marty has passed away unexpectedly. From what I am told, Marty was complaining of a pain in his eye and called his neighbor, who is a nurse. Marty was gone before she arrived. Marty was an EAA technical advisor and was a big help when I have questions about my project. Marty also let me use many of his specialty tools. His presence will be missed by throughout the aviation field. I am going to be really lost on my project now, since he is the only AP within 100 miles. I do not know the future of the airport at this time. I have decided to paint a little something on my plane when it is done for Marty. He has been a big help to me. Marty was building an experimental also. A Beaver TD. It showed some of the finest work I have ever seen. You could look for some time and not find a flaw in the wings or fuse. Services will be Monday at 2 pm here in Lakeview. I went to the airport today and noticed a sign on his office door that reads. "When my ship finally comes in. I will probably be at the airport". I believe Marty was at the airport when he felt something was wrong. I have not had to post much on this group for questions, due to Marty's knowledge, but I am afraid that if I am to finish my project, that will have to change.

Hello Christian, One of the wing ribs (#7) in the 601XL has 2 lightening holes flanged in one direction and 2 holes flanged in the opposite direction. I'm assuming the part you are talking about is like the spar tip in the XL. The purpose of the flange is to add strength and rigidity to the part. I can't see where your mistake would affect the integrity of your wing in any way.

Sheesh. I gotta chime in here... This is normal and has nothing to do with "flutter". I'd file this one right along side all the "twitchy" nonsense that was going around a few months ago. The guy hit a strong thermal due to rising heat off the steam stacks. Simple as that. I see this regularly in my Piper Warrior. The downwind 45 entry to my home airport runs right over the top of an oil refinery. Lots of heat. Always enough to bump you as you go over, and once it was enough to put me nearly on my side. You have to expect that sort of thing when flying over a large heat source. Regarding the wings bouncing - watch the normal flex of your wings (or look out the window next time you're on an airliner). Push & pull on that thing in your hands and watch what your wings do... Suggestion: go back and fly over that power plant again. Go high and slow, watch your altimeter, and expect some bumps. It won't be so bad now that you can anticipate what's going to happen. Seriously, give this a shot. - Patrick Read this topic online here: http://forums.matronics.com/viewtopic.php?p=90989#90989 ________________________________________________________________________________

Subject: Choice of planes to fly to prepare for Zodiac.
I usually fly a Cessna 152, the old shetland pony of the aircraft world. I haven't even been up in a Zenith anything yet, but am building a 601XL, currently the tail pieces until funds are a bit more free to dedicate to the rest of it. Until it's done, I want to prepare by flying something more similar to it than the Cessna. I have started transitioning to a Diamond Katana. I've flown one before, but it's been a couple of years. I just went up again yesterday in the composite beast. It was miserable to handle on the ground, pulling hard to the right, taxiing like a drunk three legged mule. I wonder if that's normal, because of the free castering nosewheel and the nice crosswind, 10kts, or if it's just that particular airplane. Maybe something is out of whack. There's not much rudder, and diff braking has to be used a lot on the ground. How does the Zodie compare? Do any of you also fly Katanas? The thing was squirrelly to take off and land. I couldn't keep it on centerline to save my soul. I'll get it, but I'll need to fly with the cfi again. The only other rentals at this particular airport are 172s. I could go to another airport, but don't know of anything more similar to the Zodiac that's available for training or rental. I've been happy putting about in the 152. I was wondering, long term am I going to be happy in a lighter weight airplane? The Katana is heavier than the 152 and the Zodiac is lighter. I was wondering if I can get happy with the Katana, is it good preparation for the Zodiac? --------------------------------- Sucker-punch spam with award-winning protection. Try the free Yahoo!

Subject: Re: Choice of planes to fly to prepare for Zodiac.
Hi Jennifer, I wish there were an easy answer to your question. Unfortunately, all planes are different, and it is unlikely to find two different models that are really similar to fly. I have not flown a Katana, but I have flown planes with free castering nose wheels. I find them very difficult to taxi and particularly difficult to take off. Add a cross wind which is trying to push your nose in the same direction as the engine torque and you have a real handful. In that respect the XL should be much nicer to handle and should be similar to the 150 since they both have nose wheel steering. I don't have my XL flying yet, but I suspect there is a significant difference in the behavior of XLs depending on which engine you have. Also, like the 150, the climb rate will change significantly depending on how many people are in the plane. Even so, an XL with a Jabiru 3300 will climb perhaps twice the rate of a 150. It has perhaps 30% more horsepower and 300 pounds less gross weight. From the standpoint of pilot training, I think all "Light" single engine planes are roughly similar to fly. When you move up to "High Performance" singles like the C-182 or Bonanza the pilot experience is quite different. The extra weight of these planes mean you must think of what you want the plane to be doing about 30 seconds in advance of the time you actually get what you want. Light singles respond immediately to changes in power and pitch. I wish we could all go out and rent XLs or 701s to prepare for flying the planes we are building. Alas, this isn't so easy to do. As far as I know there may be 3 XLs in the USA available for training and no 701s. This means you will be stuck flying whatever you can rent until your own plane is finished. Indeed, I think the more different models you fly the more you will appreciate your XL. Perhaps the 172 is reasonably close in general behavior to the XL, but if you load up the 172 it will be a lot more sluggish than your plane. I wish you luck.

I learned to fly in a Grumman which has a free castoring nose wheel, I admit it bothered me for the first few flights. However, after a few flights it becomes second nature to drag a little brake to keep it straight until the rudder becomes effective, I actually wish the XL was free castoring. On the subject of handling, I am sure you will find the XL very easy to fly and that is from a low-time pilot. The last time I flew as pilot in command was a little more than 20 years ago and I became comfortable with the XL very quickly, even with my lack of experience. I am sure you will get a response from highly experienced pilots soon, I just thought you might also want the opinion from someone that was concerned about the same issues.

I was lucky enough to fly a 601XL a couple of weeks back. The aircraft belongs to Pete Andersen and in located at Hillsboro, Oregon. The workmanship on the airplane is great and everything looked straight. Roll control is stiff (but not excessive) and pitch is sensitive. I own a Cassutt racer that is not as pitch sensitive as the XL ( however roll is EXTREMELY quick! :-) ). Now a friend owns a Lansair 235 that is MUCH more pitch sensitive than the XL. I did not operate the XL in slow flight mode but watching the control inputs while landing it appears to handle much like a trainer. My only concern for a low time pilot would be overcontrolling the aircraft in the pitch axes. As long as you could keep a relaxed hand on the stick that wouldn't be a problem. Having said this the XL trims out nicely for hands off stable flight! I hope this helps! Bob Johnson in Oregon ________________________________________________________________________________

I was able to fly it to my home airport for the extensive pattern work (including simulated engine out in the pattern, landing on the adjacent grass field) and I feel it was a good choice. Roger at Zenith suggested getting time in something light with quicker responses than "Wichita Spam Cans". The Sportstar is Rotax powered with split flaps but it is very similar to the XL. Attached is a nose to nose comparison pic I took of the Sportstar and my XL before its first flight in November. My inspector is also an EAA flight advisor and he agreed the Sportstar is a good choice. I still went to Mexico and flew with Roger in the factory XL one last time before I flew. I don't know how I could have been more prepared. First flight was uneventful. The 601XL is a very nice flying plane and if you can confidently fly a Cessna 150/152, you'll have no problem - except getting the smile off your face! Good Luck!

I can second the recommendation for the SportStar. I did half my training in one and soloed in one at St Charles Flying Service outside of St. Louis. Training in SportStars is a little more available than in XLs: Washington state, California (north, middle and south), Colorado, Minnesota, Missouri, Indiana, Kentucky, Virginia, North Carolina and Pennsylvania.

Hi I got about 30 minutes of weather good enough to fly this afternoon. The leading edge slats are off and the feather VGs are on. It seemed to want to climb like a home sick angel. I was light (1600 lbs), 30 gallons of fuel and 230 pounds of me with nothing else. I saw 900 FPM at 80 MPH. Density CG issues. Before After Cruise 103 MPH 111 MPH both adjusted to 4500' standard temp at 85% power 10.5 GPH leaned to 150 ROP No flaps stall None Buffet at 58, stall 50 indicated and GPS Full flaps stall None I assumed 38 45 indicated 49 GPS (only done once) Approach speed 50 58 Take off run Very short Much longer 250' 350' Landing distance: the breaking action was poor so I did not measure. I need to fly more in this configuration. The fog moved in and I was going to bust FARs so I landed. It is weird flying a plane that will actually stall! I think it may be a better plane to teach the kids to fly. They would learn what stalls feels like. The flaperons are effective even in the stall. The VG spacing for the outboard 3' is at 60 MM and the rest are at 90 mm spacing. I may change the spacing to 60 MM for the length of the "aileron". This hopefully will still give aileron control and inner part of wing stalling first but still lower speeds. Bill Wilcox N801BW Valdez, Alaska 280 hrs Waiting for a flying day.

Excelent topic. I vote for the Grumman AA-1 series because of its superficial resemblence to a 601XL and its inferior numbers. I admit that I have not flown it however. Consider the following: AA-1 has three feet less wing, half again more wing loading,(XL=about 10, AA-1 15 to 15.5) and higher power loading. If you can fly that ground loving pig, you should have no problem with an XL with its nose wheel steering. I have flown about 45 types since 1957 and vote for the Comanche 250 as the hardest to land and still look good, Mooney Mk-21 next. I also owned a BE-23 and Luscombe 8A. Both do not deserve their bad reps and if you can find one, they will be good practice also. Get with a sadistic instructor in any of these, and a 601XL should be a walk in the park.

Subject: Choice of planes to fly to prepare for Zodiac
Jennifer -- I own and fly a 601XL and I've been checked out in and frequently rented the next evolution of the Katana, the DA-20. I moved into the 601 from a Grumman Cheetah and there was practically no "transition." A Grumman, being heavier, gives a tiny bit smoother ride in gusty winds, but that's being picky. The difference in avionics was a bigger step than the difference in airframe -- by far! A Grumman, like the 601, has great visibility. My Cheetah had almost exactly the same performance as my 601... although the 601 has both less payload and significantly less gas consumption. A Grumman Tiger (with 35 more HP than a Cheetah) will have a much better payload and a little better speed than most 601s (with a LOT more gas consumption). The stock Grumman AA1A Yankee ... the earliest version.. probably has poorer performance than any 601, but many Yankees were up-engined. The Grumman has free castering nose wheel. Someone commented that they wished they had that in a 601. Personally, I like the nose wheel steering better than free castering, but your problems on taxi with the Katana seem unique. I'd bet on a low tire or a bent corroded axle. Look hard at the landing gear next time you fly the Diamond. Can you check the tire pressures? I do miss the sliding canopy of the Grumman! It was so nice to be able to slide back that canopy! Look around the field for a Grumman and try to get a ride. Grumman pilots are a friendly bunch. Failing that, just fly all of the single engine rental airplanes you can get your hands on. The similarities will soon be more important than the differences. -- Frank Derfler See my views and reviews at www.derfler.biz See my information for pilots at www.flyinflorida.com ________________________________________________________________________________

Hi Jonathan, I just painted my 601HDS taking from April to November of 2006. Paint stock was 1-1/2 gallons primer, 2 gallons of base coat and 1 gallon of trim color. I primed and stripped the tail feathers twice before getting it right. The actual weight of the plane after reassembly increased 13 pounds for paint and 2 lbs for a main gear plate upgrade. Of course, a lot depends on what kind of paint you intend to use as well. I went with a waterborne catalyst-urethane from Aircraft Finishing Systems, (now Hangar21 AFS). I have a paint page on my website that may help you get the job done. Lots of pictures from booth to handling, breathing gear, paint setups for parts to finish. http://www.macsmachine.com/images/paint/full/601ezfrontleftqtr.gif Good luck, Larry McFarland - 601HDS at www.macsmachine.com Jonathan Starke wrote: > Hi All Listers. > > I have now come to the point where painting is required: > > *Does anyone have an idea of the amount of paint required to paint a > 601XL* > ** > *How much (average) undercoat is required, and how much final colour > is required?

Subject: Landing Light Kit Assembly Grief
From: Brad DeMeo <demeo(at)sonic.net>
I experienced a lot of grief trying to hold together the %$@#*! landing light assembly while getting it fastened to the channel in the left wing. Every time I tried to get the bolts through the face plate and the backing plate and get the bushings and springs on and then put the darn thing up to the channel the assembly would lean and mush and the springs would fall off the bolts and boing away and the face plate would loosen and fall off and my blood pressure would rise rapidly and family would look at me in shock after a few choice words...So...I have learned a trick that works well for mounting the lights onto the channel. After drilling all holes and making the notch in the backing plates per the plans, proceed as follows: First, stand all four bolts upside down on a work bench. Second, feed the face plate over the bolts. Third, slide the bushings (11 mm each) onto the bolts. Fourth, place light in the circle of face plate with filament of bulb vertical (a hard landing will break the filament if horizontal). Fifth, place the backing plate over the bolts and over the back of the light. Then, go to Ace Hardware and purchase 8 pin clips (Servalite PC9...4 per light assembly, one for each bolt). Sixth, slide pin clips onto bolts at backing plate to hold the light assembly firm. Seventh, place springs over bolts and carefully raise the light assembly to the channel inside the wing and tighten the screws as desired/needed to focus the lights. The pin clips will save a lot of agony over trying to get the loose assembly up to the channel for final assembly. The pin clips are metal and will handle the heat near the lamp. After a dozen tries without pin clips, my first attempt with pin clips was successful and complete in less than 5 minutes!

Subject: Wing Flutter
Bill: I don't claim to be an expert on the subject but I do have 22 years of military flying with much of it as a flight engineer on medium transports. I think what you experienced was severe vortexing over the wing tips due to the hot air below the wing caused by the power plant opposed to the relatively cool air above. The extreme vortexing phenomena produced a "hammering effect" on the top of the wing causing it to flutter. I've experienced similar situations during descent and final approach during extremely hot days while flying with the Corps of Engineers in Saudi Arabia. James D.

Dave, Yeh, I tried the VGs with slats. They make no difference in that situation because the slats already give the accelerated airflow that stays attached at high AoA. The slats do that job well, it's just that they bring a very high drag that stays at all speeds including climb - note Bill's observation about "climbing like an angel" - it's the reduction in drag by removing the slats that gives the improvement.

Bill, I don't know the 801 wing but my experience on a Legal Eagle and a 701 leads me to suggest that you try 8 %. That works great on both of those wings. It's possible that at 6% the vortex is "flattening out" against the remainder of the leading edge with consequent loss of effectiveness. I tried vgs under the HS of my 701. I lost 2.5 mph and about 10-12% ROC. The only benefit that I could see was a lighter pitch feel but no increased effectiveness. I removed them in favor of the increased performance over a lighter elevator. FWIW Joe ________________________________________________________________________________

Hi, I was searching the archives for a good alternative to cleaning parts before priming (indoors) and found John Bolding's writeup below. So, what is a good, safe cleaner that I can use indoor without risking exposure to carcinogen chemicals and without causing chemical reactions on the aluminum parts? I am currently building my rudder in a corner of my living room which has turned out to be a nice comfortable work place. Am planning on brushing AFS primer/sealer on the contact points and leaving the rest of the surfaces untreated. I am also thinking of soaking the rivet heads in a thinned solution of primer/sealer before riviting. Should I consider using soap and distilled water followed by rubbing alcohol? Thanx...Eddie --------------------------- [quote="John Bolding"]OK guys , I know you should have only one subject per post but I prefer lurking to posting so I like to get it over with in a hurry. Cleaning aluminum: I REALLY hope I don't hurt anyone's feelings here and that is certainly not my intent. Over the yrs I have read hundreds of times on this list and several others that I monitor about wiping down the alum. part with some solvent( MEK, acetone and lacquer thinner being the most common)as the final prep for painting. My career in the paint spray equipment industry for 35 yrs put me in the middle of hundreds of paint film examinations to determine cause of failure. Normally the paint supplier or part washer guy was the lead role in these goat ropings but the equipment guy HAD to show up or he was automatically the cause, kinda like missing a meeting when your EAA Chapter holds elections, you WILL be an office holder if you miss. Some paints are more tolerant than others of a not perfectly clean surface, waterborne materials and powder are the least tolerant (in my limited experience anyway). Solvent is a poor choice for cleaning. Imagine coming in from the shop for lunch and grabbing a can of MEK and a rag and cleaning your greasy hands with it, no water, just a rag wet with solvent. You succeed in getting them to look a little better but you HAVEN'T taken all the dirt/ grease off, just moved it around in smaller concentrations. Follow up with a clean rag and more solvent reduces the concentrations but .... you get the picture. Now if you agitate a surfactant(soap) into the part to be cleaned,(your hands)using water and when you get all the junk floating (paint guys called it "suspended" 'cause they made a lot of money and wanted to impress the customer) and introduce a rinse(LOTS of water to flood the surface) to remove it ,you generally get a squeaky clean surface first rattle out of the box. Repeat as necessary. What I learned from all these dog and pony shows was that the oils you are trying to remove can be effective (with some coatings) down to the molecular level at causing adhesion problems down the road. Ever been at a boat dock and noticed the oil sheen on the water, it's only a few molecules thick. You CAN'T be assured you get it ALL off unless you wash and rinse. Now comes the part where 83 guys that have been painting since before birth tell me that I'm all wet and they never had a problem in wiping down a car with a rag and solvent. Save it, I heard it a thousand times. What impressed ME was the chemist who brought along a BIG microscope to one of these meetings and SHOWED me oil between the substrate and paint film where it had peeled off. Takes a lot of work to build an airplane, prep it properly.

It's actually not an alternative but rather the norm in the finishing industry. Aluminum parts going thru a conveyorized parts washer (long tunnel with several tanks and hundreds of spray nozzles) use some pretty aggressive chemicals sometimes depending on what they are trying to remove but for alum that started out clean and only has smudges and oils from our skin plus oily residue the air drill spit out Dawn or Woolite plus water gets it down to the shine. RINSE WELL WITH AGITATION !! Skip the alcohol, the part is already clean. DON'T dry it with compressed air, a LITTLE oil in the air goes a long way, use a fan or a CLEAN cotton rag. If you were outside I'd use WO-1 or Alumaprep to put in a little tooth for better adhesion but you can do that with the proper color of Scotchbrite (I keep forgetting which color it is) LOW&SLOW John Bolding I was searching the archives for a good alternative to cleaning parts before priming (indoors) and found John Bolding's writeup below. So, what is a good, safe cleaner that I can use indoor without risking exposure to carcinogen chemicals and without causing chemical reactions on the aluminum parts? Should I consider using soap and distilled water followed by rubbing alcohol? Thanx...Eddie ________________________________________________________________________________

Bill, Never is a pretty inclusive word. My original post several months ago was pretty descriptive I thought. Soap and water to remove the oils and crap ,followed by a water rinse. No big magic. Solvent wiping is just one of those things that is used by many just because it has become ingrained, not because it is better. Will you have problems every time you solvent wipe? Of course not, BUT you are kidding yourself if you think it's spotless clean. That's all I was trying to get across. No, I didn't specify what kind of soap or where to buy it but if someone has to have his hand held that tightly just to clean his parts then......Maybe I can sell some videos of a builder driving down to WalMart to get his soap. I try to lurk unless the discussion is an area that I KNOW, unlike several on this list that would freely jump into a detailed seminar on brain surgery with pages of OPINIONS on how it should be done. My delete key is almost worn out. LOW&SLOW John Bolding Eddie- I can see your problem- John's post never takes a stand other than "prep carefully".

In the latest issue of Kitplane, they listed a lot of different engines for experimental aircraft. For the Rotax, they list both a 912S and a 912ULS, with different prices.

As I understand.... The certified engine is the only one Rotax approves for night or IFR flight. The non-certified engine is specifically not approved for either. There is about $10,000 price difference. The only difference I know of is the addition of carb heat. I guess it is a question of risk and liability. Unfortunately I can't find a website that has pricing for the certified engine to confirm my information. Jabiru imposes no such restrictions.

You won't need much shelving. I built my 12x4 bench on top of a Zenith crate, and still use the crate for storage. Another Zenith crate was turned on it's side and acts as a shelf.

Don't mean to be a dummy, but does this site have anything relevant to the CH640? I just found out that the 640 is a Zenair Ltd. "exclusive". You can't even get a 640 rudder builder class at the Mexico MO location, so I was wondering if they treated the builder support info the same way.

Subject: Shelving for 601 project
Date: Feb 02, 2007
With regard to Terry Phillips' inquiry: I framed several shelves with cheap 2x2s from Lowe's, then used the plywood from the boxes of the various kits for the actual shelving. Plywood gussets reinforce the joints in the framing. The plywood is flimsy, but the components are light, for the most part. I even built a light-duty workbench for the electrical part of the job that way. Building from component kits, I had plenty of scruffy plywood to work with. I also made 2 horizontal platforms to set on top of the wing center section stubs of my 601HD. They make it easier to kneel there while working inside the cockpit area. I realize that that's not an option for an XL. A person could rip the 2x4s from the kit boxes to obtain most of the 2x2s for framing the shelves. I sold my radial arm saw to make room for the airplane in my 2-car garage, so didn't do that. As far as sizes, 18x48 has proven pretty handy for me.

There is yet another way to heat the carbs, a very simple way using 12 VDC power. I am building a 701 with a Jabiru 2200A engine. Recently I received a carb heat unit from Jabiru USA in Tennessee as part of my FWF kit. I am very impressed with the "Heater Kit", it even comes with taps to thread the holes for mounting. I am sure that Pete at Jabiru USA can provide you with price and details. Take a look at this UK WebSite for all the details on the heater unit. http://www.jabiru.co.uk/other/carb_ice_eliminator.htm I am sure this is yet another way to make sure you do not have ANY carb ice formation, without a muffler muff and all the associated stuff that goes with it.

The advantage to using the box with this firewall forward package is that you are not sucking in heated air all the time, which allows you to develop more HP. Not sure what setup you have and are installing. I also recommend installing a oil cooler thermostat, this helps in getting your oil temps up quicker and not having to tape off your oil cooler in the cooler weather.

Hi Dave, I use the threaded drill bits meant for aircraft use. I don't think they are particularly hard alloys, but they work really well and don't have problems slipping in your drill chuck as you finish each hole. I start each hole with a #40 drill. I then use #30 and optionally #20 to enlarge the holes. This means I virtually never need to sharpen or replace anything but the #40 drills. I sharpen the #40s using a bench grinder - maybe once a month - when they get dull. I am more likely to break one than to sharpen it too many times. I keep a supply of 2 or 3 spares and order more once a year or so. I am still on my first #30 and #20. I highly recommend you consider buying the right angle drill gizmo from Aircraft Spruce that comes with adapters and a few screw mount drill bits.

Date: Feb 03, 2007
Greetings all, Someone asked about carb heat for a 912 and someone else mentioned the resistive unit for a Jabiru. I also just received this heater for my Jab and ran some preliminary tests to determine current draw and will also pass along the dimensions. It is cylindrical, 30 mm in diameter and 30 mm tall, weighing 70 grams. Attachment is with two bolts to the side of the carb using the included taps. There are two electrical connections using the body of the cylinder for ground. The two coils can be operated independently which allows for a high and low setting. When the unit is cold the resistance of each coil is 8.6 Ohms for a current draw of 3.5 Amps. As the temperature increases the impedance rapidly decreases to 4.7 Ohms, however, the current draw dropped to 2.0 Amps. Cold current drain on high results in a rather high figure of 7 amps but tapers off a bit after it heats up. The kit was very complete with switches, a chunk of wire, fuse holder and all necessary electrical connectors. I was disappointed with the two SPST switches. I have already replaced them with a DPDT so as to only take up one of my switch locations. The current drain of two units operating on high for the 912 might put a bit of a strain on the electrical system. Hope this is useful Dick Neitzel Sayner, WI 701 Jab 2200 N963WB ________________________________________________________________________________

Im finally at the point of installing the canopy on the XL. In the photo guide for the inside flashing, there are alternate ways to cut out over or around the latch frame. Please advise which way you did it, and how you would do it if you had it to do over. The latch frame is thicker than the square tubing, so a cutout seems like it would leave a step up at that point in the inside flashing. Cutting around the entire latch frame would make a flatter flashing, but may not look as good. Also, the inside flashing with its reinforcing L pinch the plexi against the outside flashing. Does the top flange of the inside flashing need to be trimmed back to keep the inside flashing's main flange parallel to the outer flashing?

Subject: Cutout in the Canopy inside flashing
Dvid, I think this is the latch problem you are talking about. I have attached three photos to show what I did with it. Hope they are not too large for some of you. I made two fiberglass covers. I later discovered that I needed to cut off one corner to clear the slot for emergency release of the canopy. The fiberglass covers are not attached yet, but you can see how they will clean up the area. Jay in Dallas "deglass1" wrote: > >Im finally at the point of installing the canopy on the XL.

I went for full access to the latch over appearance. Sorry no good pic of this. I made a cut out of the inner flashing that allows finger access to open the canopy should the cabes break and more importantly I can visually check that the canopy latch is fully locked prior to take off. I have seen the canopy appear to be down and locked but the latch release lever is not fully set so it needs another compression to fully engage the lock. Also I added a 1/2" tubular cross bar about 8 " up the bow to set the width of the canopy firmly. It is also useful for compressing the locks. And with a small nylon rope attached, it prevents the wind from catching the canopy when open on the ground and possibly straining the hinges.

Subject: Drill Bit Durability
Date: Feb 04, 2007
When drilling aluminium I tend to use a high speed.... As fast as possible and just let the bit drill the hole. I too sharpen my bits on a bench grinder and if I have time I take out the bit sharpener which is actually nothing more than a fancy bit guide for sharpening. I've even reformed heads on broken bits to get a hole drilled. I never use any pressure on the drill at all. Steel is another matter. As slow as possible, fair pressure and a good supply of cutting oil. Certainly you should always have a reasonable supply of #s 40,30 and 20 because the only time you will need another one is when the tool shop is closed. If you use a deburring tool it may be a good idea to have an extra one of those on hand too. Generally I use a 3/8 bit in my hand to de burr.... Just remember to deburr gently or you could end up chamfering your hole.

Hello fellow listers: Just a comment on resharpening these small drill bits... I don't believe the typical hobbyist can accurately resharpen drill bits except with a middle to high end sharpener, and with the capital expense involved, why bother? Freehand sharpening can only approximate the angles involved (yes, I agree small drill bits do not have to involve reducing the web and other intricate angles) and with the best of freehand sharpening, you will only get one of the cutting edges working at a time. Not a good practice where the goal is nice, round holes. For amateurs like me and others who do not have the benefit of being, or working with machinists with a LOT of gray hair earned with years of trying to accurately resharpen drill bits, I say use 'em & pitch 'em. They are cheap enough; when they stop cutting quickly, toss 'em. That being said, with high cutting speeds and low feeds (light pressure on the drill), a good quality drill bit cuts LOTS of holes.

Hi Tracy, I respect your position on resharpening drill bits, as well as your analysis of some of the issues involved. On the other hand, I think there is something to be said for the other approach too. (Admittedly, I do have lots of grey hair.) Building an all metal airplane is mostly an exercise in drilling holes. For me, that means focusing on the hole drilling process is a good way to improve your building experience. It is also an area where a little learning goes a long way. (Remember, education is one of the primary reasons we are supposed to be building these contraptions.) I decided to learn "Free hand" drill bit resharpening a couple of years ago -- about the same time I started work on my XL. I found it relatively easy to turn a dull bit into one that drilled holes better than before. OK, maybe the angles on the bit didn't end up the same as they started. Does this really matter when holding a contest between tool steel and aluminum? Indeed, my reading on the web told me a drill should have a sharper angle for drilling soft materials than the one provided on store-bought drills which are designed to drill steel parts. My recommendation for anyone new to the drill sharpening process is this: Start with new bits. When they get dull put them aside and use a new one. After a while you will have a small collection of dull bits. You can try to resharpen these yourself. You can also get someone who knows how to do it to show you. Or, you can just throw them out. If you try to learn how to do this yourself, the only possible loss is some time. Perhaps you will renew the bits or perhaps you won't. I think there are three "Secrets" to drill bit sharpening. The first is to have a grinding wheel with a really flat surface and sharp corners at the edges. The second is to start holding the bit at the same angle as you do each side of the point. The third is to "Scrape" the bit upward as you finish the point to get the rake angle needed to make the drill actually remove metal. The last part (not a secret at all) is to inspect the point - if it comes out with the point in the middle of the bit then both sides are the same. If you try twisting the bit into a piece of wood it should dig in. In this case you have a nice new bit to make more holes in your airplane. Of course anyone can say this is too hard to learn or not worth the effort. Still, if you do you will feel good about learning a new skill and also find yourself a little better off when it comes to having the tool you need when you need it. Best regards, Paul XL fuselage >For amateurs like me and others who do not have the benefit of >being, or working with machinists with a LOT of gray hair earned >with years of trying to accurately resharpen drill bits, I say use >'em & pitch 'em. > ________________________________________________________________________________

Subject: Re: Remove the wings off CH601UL
Hi Ron, Congratulations, The UL is similar to the HD. Detachment of the wings is found at the wing joint covers where the wing bends. There are screws front center and trailing that secure the wing joint covers, usually a dozen screws holding the wing joint in place along the edges. Once removed, the electrical wires and pitot lines should be marked and separated at this joint. If provisions haven't been made, cut them after marking and duct tape them secure at the ends of the wings. You should have a screw at the rear spar that can be removed to separate each spar. It may have a plate nut or a self locking nut holding it. The front spar has 4 AN-6 bolts (3/8-inch) that secure the wings to splice plates each side. After these have been loosened, get a spare set of hands to hold the outboard end of the wing and push the bolts out. Then provide support both ends of each wing and slide the wing straight out from between the splice plates. The angles top and bottom will guide the wing off, but don't rely on them for supporting the weight of the wing with the bolts removed. If you're transporting the wings any distance, by truck internally, make hangars with carpet that will support the wings at the nose to evenly carry the structure. If you've got time, make a wing jig to support the wings on foam the length of the nose. If external trailer, better to lay them flat on soft foam support large area, 20% of the wing. Again, foam rented from an upholstery shop might do as they have slabs of the stuff. Drain your tanks of fuel, remove the battery and pitot tubes from the wing if possible and anything else that might be sensitive to roads. This advice presumes a lot on your mode of transport, but if you have a lot of ratchet straps, 8 - 10 should get you there. I have below, several links that suggest methods, but you may need a longer trailer for the wings. I did this in two trips. http://www.macsmachine.com/images/wing/spliceplates/full/splice-plate-bolts-and-spar.gif http://www.macsmachine.com/images/completion/full/viewleftwingjoint.gif http://www.macsmachine.com/images/TJH/HScentersection/full/wg2rack2.gif http://www.macsmachine.com/images/tjh/hscentersection/full/trailerwinching2.gif http://www.macsmachine.com/images/tjh/hscentersection/full/loadedcenter.gif http://www.macsmachine.com/images/tjh/hscentersection/full/Zenith-on-the-roadh.jpg http://www.macsmachine.com/images/tjh/hscentersection/full/zenith-to-airport.jpg Good luck, Larry McFarland Canatukker wrote: > > He My name is Ron Smit live in chilliwack B.C.

I have found one of the easiest and most accurate means of "touching up" a drill bit is a cut off wheel in my hand held Dremel. The side of the cut off wheel makes for an ultra smooth surface to work on, and because it is hand held, I can walk over to my magnifier light (have gray hair too) and steady my hands on my chest. I have pretty good results with this method. I have a couple of long drills, which I made using a quarter inch steel rod that I drilled holes in the end then brazed a smaller bit in the end. I don't want to go through the hassle of reattaching drills to these extensions so a brief touch on the cut off wheel brings them back to life. Granted using the side of the fragile cut off wheels might not be how they were intended to be used but so far I have not broken a single wheel sharpening a bit.

One thing I have not seen mentioned in this thread has been the Drill Doctor. The Drill Doctor will sharpen a drill bit to a perfect point in under a minute. You will be surprised what a difference it makes to always have a sharp bit. In addition to getting better holes, there is a time savings in drilling every hole with a sharp bit. It is designed to make a perfect point and removes a minimum of metal doing it. I have had one for years and have all but stopped buying drill bits. I drill a lot of steel, so drill wear is a constant issue for me. They make several different versions starting at under $100.

Just passing this on in case someone is looking for a core or parts or project... Contact Dave at davedent(at)comcast.net for more information and pictures if interested. I think that he is asking $5K or best offer. I am only forwarding this on and have no more information than what is below. ---------------------------------------------------------------------------- ---------------- ...the engine has just under 100 hrs on it. It was used only as a test cell engine. In the cell it was used to see if we could get 80hp at 80,000 ft. We did it with three turbos and electronic ignition and fuel injection. We saw 65hp at 90,000. After the test it was left in the cell for a good six months and never touched again till we put it in storage in a transportainer. Now it is in my hangar. It is as we took it out of the cell, without the exhaust and intake system installed. If anyone wants it they can have the removed systems. Along with the engine. It will come with a very expensive oil pump and a bunch of other hardware. The engine would make a very good short block. ---------------------------------------------------------------------------- --- ________________________________________________________________________________

If you have a carb you can get carb ice. You may have to be a member but here is an excellent article on the subject with a great chart showing how ice even if the ambient temp is over 100. http://flighttraining.aopa.org/members/student_pilot/presolo/articles/58.cfm [quote="arno7452(at)bellsouth.net"]Dear Listers, I am installing 912 ULS on a CH 701. Due to its cost and perhaps debatable utility, I have been advised to leave it off. I sure would like to hear some comments from the list as to whether this is a good approach. I am taking lessons in an Evektor Sportstar with 912S engine. So far, we have never used the carb heat. I am flying in Goldsboro, NC. That is about 60 miles east of Raleigh. As I recall flying the Continental O-200, we used carb heat anytime under 2K rpm. The POH on the Sportstar only requires carb heat if you suspect icing. i.e. engine starting to lose power and run rough.

I have had the Drill Doctor XP2 for about 2 years. I have not had any problems with it at all. It does have a replaceable grinding wheel, but can hardly see any wear on the wheel and have done a lot of sharpening of #30 and #40 drills. It really does a great job, nicely centered grind on the flutes every time. I also do a side cut on the flutes, it does that as a second step in the sharpening process. Makes the drills go thru aluminum just like it was not even there. I do use a high speed small air motor to drive the drills. It comes with a "training" DVD that takes you through the entire process and even shows you how to service your tool. They have them at Home Depot and sometimes they have a $20.00 rebate slip right along with them. Got mine that way! Highly recommended!

Listers, Many thanks for all the good comments regarding Carb Heat. I have discussed the issue with Lockwood and Zenith in Mexico. Here is summary of discussion with Zenith: The cowling for the CH701 maintains a relatively warm environment. If the Rotax airbox is not installed, NO carb heat is required. So, my CH701 will be using the new cowling and there will be no airbox. So, I will not install carb heat. These comments are based on discussion with Sebastian Heintz at Zenith today 2/6/2007. Sebastian indicates there are hundreds of Rotax 912s that do not have carb heat. They are doing nicely. He also estimates about 3 hp is lost by not using the airbox to draw in cold air. To the best of my knowledge, I received no comments from Zenith owners flying behind the 912 without carb heat. The carb heat upgrade can be retrofitted at a later date. It is a collar that fits on the carb and circulates cooling fluid. Fairly simple install I'm told. Again, many thanks for your interest and comments.

The Facet 40105 has been working fine on my XL/Jab3300 for over 200 hours. The Bing also has given me no problems and has been working smoothly up to 12,500 ft. (max I have cruised at to date) For info, below are excerpts from my POH on the fuel system in my XL. Tony Graziano 601XL; N493TG, 204 hrs -------------------------------------------- B. FUEL SYSTEM The engine is fitted with an altitude adjusting Bing Carburetor. The throttle is controlled via a cable to the carburetor. The carburetor has a choke for cold starting and is controlled via a cable to the choke. Fuel is screened by a small finger strainers in the fuel tanks, a gascolator located on the aircraft C/L below the cockpit before the rudder peddles and just prior to the electric fuel pump, and filtered between the firewall and the mechanical fuel pump. There is no priming system. Fuel travels from the tanks to a fuel selector, to the gascolator, through a solid state check -valved free flow electronic fuel pump, through a fuel flow sensor, through the firewall, through a fuel filter, to the engine mechanical pump and then to the carburetor where it is metered to the engine intake manifolds. The Bing Carburetor has incorporated the Fuel Economy Modification IAW Jabiru JSL002-1 3. FUEL SYSTEM A. FUEL TANKS B. FUEL SELECTOR C. GASCOLATOR D. FUEL PUMPS E. APPROXIMATE FUEL BURN RATES at CRUISE F. FUEL TANK DIPSTICK READINGS A. FUEL TANKS N493TG has four 12-gallon fuel tanks, two in each wing. The fuel filler is on the outer portion of the tanks and the wing dihedral forces fuel to the inner portion of the tank. Each tank has a VDO 10 - 180-ohm fuel gauge float type sender installed in the inboard cell of the tanks. Each tank also has a standard fuel drain on the aft rear section of the tank for taking fuel samples and fuel draining. Each tank contains approximately 1/4 gallon of unusable fuel based on the position of the fuel pickups. The fuel caps latch should face aft when installed to prevent airflow from unlatching the cap in-flight. The O-rings of the latches should be lubricated annually. WARNING Static electricity can cause a fire when fueling or de-fueling if proper grounding procedures are not used. B. FUEL SELECTOR The fuel flows from each fuel tank to an ANDAIR P/N FS20F8-F, five-way fuel selector on the center console. The selector can select either RIGHT tank, LEFT tank, RIGHT AUX tank, LEFT AUX tank or OFF. When selecting a fuel tank, ensure the selector is in the detent and a positive click is felt. WARNING Avoid switching fuel tanks at low altitude or just prior to takeoff in the event of a selector malfunction. C. GASCOLATOR After the fuel selector the fuel flows to the gascolater. The gascolator has a fine screen for fuel filtering and a bowl to allow water to settle. There is a quick drain on the bottom of the gascolator to allow taking fuel samples during preflight. The gascolator is covered externally by an aerodynamic shaped FOD guard to protect the gascolator from any foreign objects that may be tossed up by the nose wheel or prop. This guard permits access to fuel sampling the gascolator during preflight and can be removed to allow removal of the gascolator bowl and screen filter during inspections. WARNING Ensure the gascolator drain is fully closed after taking a fuel sample. Failure to properly close the fuel drain can cause leakage causing fuel starvation. D. FUEL PUMPS A FACET P/N 40105, solid state, checked valved, electronic fuel pump is installed on the centerline of the cockpit floor just forward of the gascolator. Another mechanical fuel pump is installed on the engine. Prior to starting, the electronic fuel pump should be turned on for about 10 seconds and then turned off. The electronic fuel pump should be used for take off and landing and be OFF during cruise. -------- > Subject: Zenith-List: Bing carb on Jab3300 > From: "chris Sinfield" <chris_sinfield(at)yahoo.com.au> > > > I found this on the Yahoo Jab Engine site any one had similar problems as > the fuel > pump that was sent with my XL kit was the 40105 > Chris.. > > frm the site..... > > first engine start went well except that i had fuel leaks from the bing > carb. i have a facet 40105 electric fuel pump that really overpowered > the needle valve controlled by the floats. this is the pump i understand > is used by many jab owners. after a short engine run without the elec. > pump i shut the engine down as the manual pump was also causing fuel to > leak. leaks were coming out the vent for the fuel bowl. > i spoke to bing and was told that these needle assemblies come with > several spring stiffnesses. i had the weakest spring assembly. bing is > sending me the medium stiffness spring. bing said the stiffest spring is > too stiff and not offered any more. bing said a pulolator pressure > regulator is commonly installed in the fuel line. bing also said they > get a lot of calls for the same problem from a lot of 40105 owners. > maybe i should be looking at a facet pump of around 2-2.5 lbs. i believe > they are made and would be more desireable because these lower pressured > pumps have no check valves. thus no possible valve to stick. > does anyone have anything to add to this or offer any fuel pressure > info? > and also, jim of pacific jabiru was helpful and patient with my phone > calls as all of this was going on during the first start attempt. > > > [Question] [Question] > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=93139#93139 > > ________________________________________________________________________________

No info on that particular brake, but ANY brake you buy will need to have a radius machined into it, or used with a 'bend wrapper'. The bend wrapper (or whatever else you'd like to call it) is nothing more than a strip of .040 aluminum bent on the brake, and left there. Just tape it to the top die/punch and go on to bend your parts. The .040 stip essentially increases the bend radius of the original punch. Depending on the existing radius, and the effectiveness of your brake, you may have to use several strips to achieve the correct radius. This sounds like a half-@$$ed method, but it's the same method used in multi-millin dollar production shops to achieve a non-standard radius. just use double sided tape to hold the strip tot he punch. If you were careful, you could probably achieve a satisfactory radius on the stock brake parts using a belt sander. Just be ready to spend another $100 if you're not careful.

Remember, you're looking for a .125" radius on the brake. Two layers of .016" material is still only slightly larger than a .032" radius. The thin .016 conforms too tightly to the original brake radius. You'll find that a couple of strips of .040 will usually be just right. If nothing else, use three stips (.040+.040+.040= 1/8" radius). Hope that helps... The 30 inch brake from HF has worked well.

Hi Ryan, I haven't seen that particular model brake from Harbor Freight, but I bought one of the smaller ones they sell. The price is quite low, and the picture in the downloaded assembly manual makes it look similar to the smaller ones. It says it is limited to 90 degree bends. On the smaller one, I was able to grind the stops so it would go farther and allow you to make an actual 90 degree bend after the snap back. The hold-down bar seems to be designed for no radius - just like the smaller model. I started with one of the small ones (maybe 18") and played around with it for a while. I wound up buying a 24" one from Grizzly which required extensive modifications to work at all. However, the Grizzly tool was much heavier and almost able to clamp an 18 inch piece of aluminum well enough to actually make a good bend. I tried a couple of different ways to get the 1/8" radius required for most parts on our planes. I tried gluing a 1/4" round rod to a flat piece of metal and putting it under the supplied hold down bar. It didn't last long. The final winner was a piece of 1/4" aluminum cut from an extrusion which already had the rounded edge needed when it came from the store. This has worked well. I don't think you will find the 4 foot brake from Harbor freight to be very useful. On the other hand, the smaller ones which cost a lot less (around $30) would make a great first brake for you to fool around with and learn the ropes. After making a few test parts with the Harbor Freight brake and learning how to form the 1/8" radius you need you will be in a much better position to build your 8 or 12 foot brake. You might also decide that the larger one is not worth the trouble and use a local shop to do the long bends on proper hydraulic machines.

Ryan, You might want to take a look here for some good ideas: My experience with the wrapping metal around the nose of the leaf brakes is, the nose piece needs to be adjustable fore and aft.

Ryan, I have a similar Harbor Freight brake: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=91012 This has come in very handy several times. I placed a .040 cover over the upper clamp, and have no radius issues. The math performed earlier is good for math class, but in reality, the .040 is not going to exactly follow the edge on the upper clamp unless you beat it that way with a hammer. You obviously don't plan to bend the spar with this brake. -For just about anything else, it works great. BTW, the brake I use at the CNC machine shop for aviation STC'd equipment uses the same .040 sheet for radius. It works...

Ryan- The Harbor Freight brakes are well worth the money, but to do any serious work, you need something larger than 40". I personally have an 18" for taking care of the little stuff. For bigger work, (Especially if you intend to scratchbuild) check out the "Home Depot" brake in the archives or on 601.org. Of course, there are those of us that are still waiting for the plans for a really neat 48" brake promised to us years ago by Homebuilder Helper. Forgot all about that! Oh Zodie..........

The bend wrapper (or whatever else you'd like to call it) is nothing more than a strip of .040 aluminum bent on the brake, and left there. Just tape it to the top die/punch and go on to bend your parts. The .040 stip essentially increases the bend radius of the original punch. Depending on the existing radius, and the effectiveness of your brake, you may have to use several strips to achieve the correct radius. This sounds like a half-@$$ed method, but it's the same method used in multi-millin dollar production shops to achieve a non-standard radius. just use double sided tape to hold the strip tot he punch. If you were careful, you could probably achieve a satisfactory radius on the stock brake parts using a belt sander. Just be ready to spend another $100 if you're not careful.

Regarding the 40" Harbor Freight brake, I have used that for fabricating parts for my 701 project for the past couple of years and it works great. To get a 1/8" radius I put a sheet of .016 in the brake, bent it over the edge and left it there. This will give you the 1/8" radius. This brake gives you the most utility for the money invested of any brake I have seen around.

Subject: A Few Questions for Scratchbuilders
Date: Feb 07, 2007
Thank God for this forum! I have two questions for the scratch-builders out there. The First: I am not clear on the meaning of one of the diagrams on the 601 XL rear wing rib drawing 6W6. My question is this: The detail diagram of the edge of the forming block on the spar side, says to "file the top of the block 90 degrees to spar flange on 25 mm". A length dimension of 214.9 mm is shown as the spar face length of the forming blocks. The distance from X=0, Yu=147 to X=33.8, Yl=66.5 (as shown in the curve point table) is 216.16 mm, implying that 1.2 to 1.3 mm should be removed by the filing operation. Note: this is not the joggle, since the joggle is clearly stated, in the blank forming diagram, to apply to both top and bottom flanges. The filing is only done (per drawing) to the top forming block edge. Am I correct in executing the following steps in this order? 1. Sand edges of forming block to the curve table points. 2. Sand 1.2 mm off in the region shown perpendicular to the spar side edge (should leave a spar side edge 214.9 mm long, but it leaves a flat top surface far longer than 25 mm). 3. Apply 1/8" radius to forming block edge all around. 4. Sand 10 degree springback all around forming block (except rear channel side which should be 13 degrees). This will result in a forming block with a straight section abutting the curve points. The reason I'm being fussy about this 1.2 mm is that, this is exactly the region in which the tolerance should be held to a mouse whisker. Can some of you who've been through this step tell me if I'm interpreting this correctly? Second Issue: The rear panel for the lockers is shown on the drawing as 498 mm length with sides of 225 and 218 mm. What isn't shown clearly are the angles in which these sides meet. I'm guessing that the top side is perpendicular to the 225 and 218 sides, but it could also be the case that this piece is cut trapezoidally, or even the perpendicular side could be the bottom????. Maybe I'm overlooking an obvious clue here; in case I am, please bear with me. Someone who has installed the lockers please clue me in on the correct way to cut this piece. I do appreciate the help in this forum! Doug ________________________________________________________________________________

Thanks everyone. It sounds like Caleb was giving me straight skinny about the trim issue. I think I do have the latest trim tab design - inset into the elevator and taking much of one side. I still think the decision to reduce the flap deflection might have been related to the design problem as much as the trim issue, but I guess that doesn't really matter. Can anyone tell me if the full flaps (30 degrees) is really helpful in dumping altitude? Will 20 degrees be a big improvement over no flaps at all? I guess my choices at this point are whether to settle for the current limit of 20 degrees or demand or design a larger deflection.

Subject: Re: A Few Questions for Scratchbuilders
The locker panel is almost rectangular, but actually a trapezoid (almost?). This is because the wing tapers a little bit at that point. I suggest you start with it cut as a rectangle and adjust the few mm needed as you fit it in place. If you build it according to the photo guide, the bottom skin will already be riveted in place, and I suggest you fit the angle that meets the top skin before trying to drill pilot holes in the rear panel. One issue to watch here is the orientation of the flanges on the rear ribs surrounding the locker. The drawings are a little vague (wrong?) on this point. The proper way is to have the flanges on the rear ribs on both sides of the locker facing away from the locker. This gives you a smooth side wall on both the inboard and outboard side of the locker. If you get this wrong, the rear panel for the locker will need to be a considerably different size.
