FYI -- after a couple of nose slam-down landings at near stall speed (with extensive and expensive firewall damage), our landing procedure is a 60 kias half-flap approach with a relatively shallow and fully controlled touchdown at around 50 -55 kias. It makes little roll-out distance difference (this is not a STOL airplane) and keeps the insurance company happy. I wouldn't sweat the elevator trim business and would very strongly recommend not getting into that envelope.

I've got both styles on working aircraft and I will go measure the travel on both but it just seems to me the new unit has less but I will confirm this tomorrow. You may be in fact correct.

I've had both the old one with the exposed micro-switches and the new sealed one (circa Nov. 2008) and measured the travel of both. Unless you crack open the sealed unit you can't adjust the travel. From the fact ory the travel of mine was 2 and 1/8th inches or 54mm. The plans page for new style actuator here (dated 11/06) show a travel of 50 mm: http://www.zenithair.com/zodiac/xl/data/6b19.pdf For the old actuator the rough settings shown for the micro switches show in 6-B-19 (dated 08/05) give about 2 inches of travel (63mm - 12mm = 51 mm or about 2 inches) but this adjustment is refined for 30 degree travel as specified on 6-S-3. For both the old and new plans the center-to-center length of the arm that connects the actuator to the flap torque tube (6B19-3) is listed as 170 mm. And the arm that drives the flap (at least on the right, 6B19-1) has a center-to-center distance of 105 mm for the old and new design. So if the actuators travel the same distance and the arms are the same length then how did the angle swept change? Or has there been a third design? -- Craig From: owner-zenith601-list-server(at)matronics.com [mailto:owner-zenith601-li st-server(at)matronics.com] On Behalf Of afterfxllc(at)aol.com Sent: Sunday, May 16, 2010 4:04 PM Subject: Re: Zenith601-List: Zenith-List: Alieron Trim/ flap travel Yes the new style actuator has less travel and my test pilot had the same concern about lack of elevator trim with full flaps but with half flaps and keeping his speed up it works fine.

Who knew you had to be a machinist to install the upgrade! I'm learning about all sorts of new things: transfer punches, reamers, solid rivets. The plans state that the main spar attach bolt holes in the center spar should be drilled undersized then reamed to the proper diameter (5/16). To me that appears to be a pretty open ended statement. If you google "reamer" you get many and varied hits for all different kinds of reamers. Does anyone have a suggestion as to what kind of reamer we should use and where to get one? Should we also ream the bolt holes for 6-ZU-2-4? What have other people done? Thanks! ________________________________________________________________________________

Hi Lee, Reamers do indeed come in a lot of different forms. For this kind of work, I prefer hand reamers. They tend to be several inches longer than other kinds and mount in tap holders. I selected "Left hand spiral, Right Hand cut" for my Zodiac XL spar work, but other choices would probably work about the same. What you probably don't want is "Chucking Reamer" types. These are meant for milling machines and fancier "Machining Centers" where the machine provides the stability rather than the shape of the reamer. I like to drill 10 or 20 thousandths undersize before reaming a hole in aluminum. There are many "Cutting Tool" vendors that all supply good stuff. Travers tool is a good one on the East coast, MSC works well in most parts of the USA. I don't know which holes should be reamed, so I'll let someone else address that question. I personally think this is a big issue when a wing is attached to the fuselage with one bolt, but when there are six of them I doubt the perfection of the hole is a big deal.

Subject: Re: upgrade question
Hi Lee I am definitely not a machinist, but I can tell you what I am doing, though I am still in the early stages. Most of what I've learned about reamers was by buying the wrong thing at $18/ea. I think the best ones are the "piloted reamers," e.g., http://browntool.com/Default.aspx?tabid=255&txtSearch=reamer&List=1&SortField=ProductName%2cProductNumber&catpageindex=2&ProductID=1010 which has a short pilot of 0.2969" dia. to fit in your sub-5/16" pilot hole, followed by a section of 0.3125", to ream the hole precisely to 5/16". That assumes that you hold your drill perfectly normal to the spar---or are using a good drill press. There are (slightly) cheaper reamers that are not piloted. I don't trust my hand drill skills, so I think I'll bolt my drill press to my work table for the reaming. I'm also using reamers for the bolt joints through the 1/8" spar cap, spar cap doubler, web, and spar root doubler plate. I'm using AN4's rather than AN3's, because the holes in my spar cap and my spar cap doubler are substantially larger than 0.1875" . I bought a .247 x .231 HSS Piloted Chucking Reamer for those holes (my AN4's measure about 0.245"). Good call on the 6-ZU-2-4 bolts. You're way ahead of me. I believe that the bolts in the main spar are loaded primarily in shear (so a tight bolt hole is critical to avoid stress concentrations, which can lead to fatigue failure). I suspect the center spar bolt are in tension between the bolted spar caps, but in shear between the spar caps and the spar uprights. In any case, I do not believe that a tight bolt hole hurts (assuming that holes line up in the different layers), so I'll plan to use my .247 x .231 AN4- piloted reamer for those holes also. 'Good idea.

Lee, The reamer you want to use is called a chucking reamer. It has straight flutes and can be turned by hand or by a drill motor. I suggest you turn it by hand. A piloted reamer is handy but not totally necessary. 5/16 is .3125 The upgrade instructions specify the tolerance to be +.004 This means you holes cannot be larger than .3165or you will need to go to an over sized bolt that is less than 3/8th. these are very expensive. The reamer size you want is .3125" It is not necessary to ream the bolts in the main spar. These bolts are not in shear really, they are mostly in tension. as the spar is stressed the caps want to separate or bend away from each other. this would allow them to collapse. The bolt (&or rivets) hold them together and force them to flex in the correct direction which is edge wise. Clear as mud?

Well, the harmonic frequency of a beam like this is inversely proportional to the length squared, so your harmonic frequencies will be about 47% of that of the pushrod in the RV-4, assuming you use the same size tubing.

John, On the issue of a chucking reamer, I did use one by hand. I don't recommend it for everyone. By using the existing hole as an alignment guide and then having the hole in the new metal only 0.015 under size, it was very easy to get a clean hole. The clear issue is that one must not put any side pressure on the existing hole. That is a matter of practice. Even a hand reamer can take some metal off the existing hole if one is not careful so there is no perfect solution short of standing the wing on edge and mounting a "mini" drill press on the spar to ream out the holes. Even better would be to have a special reamer that only had cutting flukes for the first 1/8 inch and then was smooth but the same diameter.

Why do the bolts have to be smaller than 3/8"? Is it edge distance that is the problem? With all the drilling and back drilling it's hard to get a perfect hole. The bolt may seem tight but the hole might not be uniform through many layers of material. I thought of drilling a larger hole after all the 5/16 bolts are in place by removing one bolt at a time. A 3/8 bolt is much stronger than 5/16.

Good question. I've heard of several people who have done that, and apparently, nobody has complained about the result. While we're at it, do any of the guys with real-world structural backgrounds have any strong objections to using AN-3 bolts instead of rivets? Zenith said they don't mind, and several A&Ps have said it's okay. With the proposed number of bolts in the spar, the .008 (average) difference isn't going to matter.

OK - I know this subject has been discussed before but I thought it would be interesting to hear what people have to say after some time has passed. I'm busy installing the mods in my wings at the moment but in the future I will be back to building my fuselage. I have a Jabiru 3300 going up front and my original intention was to install the gear flat side back. More recent plans call for turning the gear around to avoid nose heaviness which results in the nose plopping down on landing. On the other hand, I have heard that with the gear turned around it is easier to ground the tail when boarding, especially when it's a big guy (like me). That would be a little embarrassing at the least :-) I'd like to hear from guys who have done it both ways (with a similar weight engine) to help me make a final decision as to which way to go.

Hi, Tim! I'm also a "big guy", and I'm in the process of turning my gear around so the flat side faces forward. I'd much rather shift my weight forward when boarding, then put up any longer with the inability to hold the nose off after the mains touch in a full stall landing. Given the low rotation speed of the 601, and the "nose heaviness" with a Corvair, I think it makes sense to move the pivot point forward (assuming tricycle gear). But I'm used to thinking about the tail going down while boarding - this happens withh Grumman Tigers all the time when two big people get on the boarding steps at the same time. The solution is to install a skid at the rear tie-down eye, which will protect the tail and the ring.

Chuck, I looked for some oversize AN3's for the spar root doubler joint. They were very hard to find, and pricey when I found them--check out: http://www.arizona-aero.com/nas_list.html You'll need to request a quote, and, for that you'll have to decipher the part number codes. Ultimately, I decided to go with AN4's. They are about 40x cheaper than over size NAS6204-11's. (I believe, but I'm not positive, that oversize AN's do not exist. The oversize bolts all seem to be NAS's. I suspect it's a tolerance thing.)

Well put Pavel! I think this is why I may go to .375". The layers will be held in higher tension. The bolts are stronger but may be very close to being out of tolerance (edge distance) But at least the holes can be reamed after all the parts ate in place (only from the aft drilling forward) opening the hole from a somewhat sloppy 5/16" to .375 with the final reamer being .374 (subject to testing).

Gentlemen, The part #'s for the over sized bolts are: NAS6205-22x NAS6205-23x the "X" in the part # specifies the over size. Also there is a "y" for the next over size. I forget if the oversize increments are .010" or .015" for the "X" but the "Y" is 2 times the "X" dimension. (.020" or .030"). Regardless I had a very lengthy discussion with Caleb about this because I have 2 airplanes in my shop that will require over sized bolts. Caleb told me to "avoid over sizing to 3/8 if at all possible." His reason for this is that at 3/8 the minimum edge distance becomes dangerously close. My experience with sourcing the oversize bolts is that they are very rare and very expensive. I sourced certified bolts @ $40 each. I was lucky to find some surplus bolts without certification papers for $10 each and so I bought all they had. Unfortunately this still is not enough to complete both airplanes. so the search continues. Just because the animal exists doesn't necessarily mean it will be easy to hunt! Or that you will bag one For what its worth: A 2 flute drill will produce a hole with 3 corners. A 3 flute drill will produce a hole with 4 corners. A 4 flute drill will produce a hole with 5 corners. and so on. With each additional flute the corners decrease in depth. the formula is N+1 (N=number of flutes).

I removed the top skin on my right wing today. Because of some pesky stems that protruded too high I had trouble with a few rivets, resulting in some very slightly enlarged or out of round holes.

If you used countersunk rivets did you pull them with the nosepiece ground for the A5 rivet or make a new one? Thanks!

Tim, one of the airplanes I am working on needed some A6 rivets. I used the counter sunk style and made a new tip for the rivet gun. If you use an automatic center punch to knock the mandrels down before you drill you will need fewer A6 rivets.

TIM- On the rivets that have stems that keep you from drilling and cause the drill to go off-center and make a mess- Use a center punch and a light hammer and try to drive the stem back into yhe opposte end . Then try drilling the rivet hear off. Sometimes it takes a few tries to drive the rivet center in. Be carefull you don't bend or dent the aluminum skin. I did have to use a few #6 rivets a couple years ago when I opened the leading edge on both wings to take out the two aux. tanks but don't remember which pulling head I used. Presently, I have both wings off with the topskins removed along with both leading edge skins. Also, the center section srar is out. I have stripped both spars fron the wings for easier handling. I have decided bolt yhe new heavy angles onto the spars after trying unsucessfully to rivet. The left wing will be closed and finished in about a week or two. Then comes the right wing and then the center spar and fuselage work. Looks like an all summer job. If you get a chance take a trip down and see my slow progress.

If you used countersunk rivets did you pull them with the nosepiece ground for the A5 rivet or make a new one? I used A6 rivets that I bought from Zenith. They are the countersunk type, just like the A4's and A5's we already use, just a little bigger. I bought a bigger hand riveter and ground out one of the nosepieces that came with it. For removing the pre-existing rivets, I used one of those $3 "spring punches". I ground down the tip so it could fit into the holes in the rivets. For each rivet I would punch down the stem, and then using a drill bit *larger* than the existing rivet, I would carefully drill into the rivet head until it popped off (without touching the underlying skin or enlarging the existing hole). Then most rivets could be pushed out the rest of the way with a second pop from the spring punch. Stubborn ones got drilled out with a smaller drill so as to not enlarge the existing hole. A4's are harder to remove than A5's, as A4's more often tend to "spin". To get around that, I carefully drill into their heads at an acute angle until the heads come off. It took a while, but I've got one wing just about done now. By far the biggest problem I've had is "garage rash" as these skins are taking a beating and getting all scratched no matter how careful I am. I want to polish my skins, but I don't know how it will look with some of the scratches I can already see. -------- Patrick XL/650/Corvair N63PZ (reserved) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=298574#298574 ________________________________________________________________________________

Hi Patrick, I have found a slightly different approach for removing rivets. I do nothing before drilling, and use the same size drill bit as the final rivet hole. I drill very slowly - using a variable speed battery powered drill. Most of the time the head starts to spin when the drill bit reaches the skin and I am finished. In cases where the stem gets in the way the drill bit goes off center and I stop before the bit reaches the skin. Then I use a normal wood chisel and mallet to tap off the remaining part of the rivet head. With the rivet partially drilled this goes very easily. I have done a lot of wood work over the years, so it is easy for me to position the wood chisel so it doesn't damage the skin. For less experienced wood workers, I would recommend a little practice in partially drilled rivets in scrap pieces. After the rivet head is removed, I use a slightly smaller pin punch and mallet to remove the remains from the hole. Some times this makes a bit of a dent in the skin, but this is easily removed with auto body dolly and hammer. ------ For removing the pre-existing rivets, I used one of those $3 "spring punches".

If your aircraft isn't painted you can use a wood chisel to remove all riv ets and leave no dents and it makes the tail removal much easier also. I use a chisel to remove the solid rivet heads then just punch out the sho p end with a punch and hammer over a vise. I have gotten to the point that I can disassemble the center spar and remove all the rivets in 30 minutes . I do the same with the wing spar but I have to drill half way thru them and use my 2X to punch the shop end out. If you use a chisel you need to smooth the bottom so it doesn't scratch or gouge the aluminum.

Why would you hold a higher standard for the safety of others than you do your own? The fact that you think you can drill a hole with a 2 fluted drill bit that is some how good enough with out reaming, when the directions specifically call for a Reamed hole, only proves that you don't understand the reasons behind the process. > > And as a matter of fact none of the wing attach bolts broke or were the cause of wing failures.

No one is concerned that the bolts are breaking. Did it ever occur to you that the reason that spar broke at that hole was because perhaps the fit between the bolt and the hole was too loose and it was able to work the hole open further until it finally broke? Or maybe it was one of those sloppy building techniques you mentioned earlier that hadn't failed yet but finally did? The difference between a professional and an armature is that a professional knows enough to know what he doesn't know, and is able to park his ego long enough to ask the questions he needs to do the job right. Your personal attacks are only a sign that you have exhausted your technical experience and knowledge.

Hey, Brady. Not to be a picky twitch, but the word "armature" in your post to Jeff describes a thing that spins around with a lot of motion, but in the end, goes nowhere. "Amateur", on the other hand, is a thing that expends a lot of energy but ends up with little to show for it. Come to think of it, you're original usage may be correct after all...

I said I was done with th e pissing match but they can't let it rest. So now I am done with the pissing match again. LOL BTW are you going with push pull tubes? The ones I installed work great bu t it isn't a quick conversion as you know but when I talked to Sebastian about them he seemed to like the way I went about doing it. We are Flying 962T again tomorrow and that will end the 5 hour Phase 1 and I think Thomas is coming to pick it up this week. I am going to install a Van's slider canopy in my next 601 that I am build ing now along with a Corvair and push pull tubes. Believe it or not the 60 1 is 20 mm wider than the RV-7 and I think the only thing that I need to modify is the turtle deck as the RV has bulkheads that are flat at the to p and rounds as it nears the tail.

Subject: Re: slider canopy
Date: May 23, 2010
An RV has pretty much straight sides where the 601/50 has a pretty good flare front to back. How are you planning to have the narrow front part slide over the wider back part? I've been thinking about this, and it seem like the canopy would have to lift up, a lot, more than on an RV, before sliding. For what it's worth, the 601 also has more head and leg room the than an RV7 (only one I've attempted to get into - and failed). I really hope you do this, I'd love to see your solution.

I too, spent 2 years occasionally needing to remove a rivet only to run into the stem and over sizing the hole. Then I heard from Mr. Garrett on the use of a chisel. I absolutely could not believe I had never heard of this technique before. I use a half inch wood chisel and have removed several hundred rivets now and everyone of them left the hole completely untouched. The head just shears right off and the back of the rivet can be pulled out with a pair of dikes or pliers or if necessary, a light tap of a punch. I do not have any painted parts but with the flat side polished a little, it leaves very little in the way of a mark. In addition, you can get to any head at any angle unlike a drill. I don't believe I will ever drill out another rivet. Try it. You just won't believe it !

No one is concerned that the bolts are breaking. Did it ever occur to you that the reason that spar broke at that hole was because perhaps the fit between the bolt and the hole was too loose and it was able to work the hole open further until it finally broke?

Subject: Aileron Stop after Mod
From: "Tim Juhl" <juhl(at)avci.net>
Date: May 24, 2010
When I was fitting the doubler around the aileron pushrod hole I found it necessary to remove the external aileron stop (although it wasn't mentioned in the modification instructions.) I did a search and see that Zenith wants the external stop retained even though we're supposed to add a stop in the fuselage as well. Did the rest of you just move the stop outboard to clear the doubler or what?

Jeff, I would be happy to talk about off shore manufacturing, defective crankshafts, Corvairs, my accomplishments as a professional or what ever else you might have on your mind, but if you're going to change the subject at least start a new thread. Saying that you want to end a "pissing contest" and then taking a parting shot is contradictory. It is a common strategy for someone who has reached the end their argument/ debate or what ever to try and create a diversion and or change the subject to try and direct the attention away from themselves. We see this in the political arena all the time. It doesn't work here any better than it does there. The fact that your airplane is done and flying only means that you started before I did, you assembled a kit where as I am scratch building, and I would be happy to compare workmanship at any venue of your choosing once I am done. My 601 will be done far sooner than my 701 so at least we will have apples to compare to apples.

Subject: Bad takeoff, but still good landing
Last sunday was a beautiful day here in my region and I couldn't resist flying after completing the engine portion of my annual inspection. I changed the oil, tested the compression (150 +-5 on all cylinders), timing OK, removed valve covers... all neat, cleaned air filter, etc, etc... all was GREAT :-) Well, I did my preflight inspection, did my runnup (at about 3600 rpm) near runway 15 of Beloeil airport, positioned myself on the runway and applied full throttle. The feeling of accelerating and taking off on such a beautiful day was enjoyable... for about 4 seconds... I climbed to about 5 feet in the air and then, total loss of power (like lack of fuel). I was getting close to mid-runway (maybe even past it... don't remember), and I pulled the throttle, and landed the plane. The engine was still running at low rpm. Then I went to an area to check the engine behavior... when I raised the throttle above 4000 rpm, it would do the same thing. I then tried at lower rpms... would just take more time and at about 2100 rpm, the engine would run smooth, miss and run smooth again. My first idea was the fuel supply... so I disconnected the fuel line and filter from the carburetor and tested the fuel flow.. very good.. certainly, the issue is not that. I then removed the top of the carburetor (Holley 5200) to see if the bowl has fuel and to see if the float valve operates properly... bowl was OK (but with some small debrits on the bottom) and floats appeared to work OK (I applied fuel pressure while playing with float movement and making a mess besides the catch can I was using). My questions: what failures could create this condition? 1. fuel system ? (I think so) 2. ignition system ? 3. cam shaft ? 4. ? Oh... a funny thing... I'm surprised to notice I did not get excited through this... I don't think my heart beat got any faster during that failure. I got a strange feeling that I'll miss many good days of flying opportunities now. ---------------------------- Michel Therrien CH601-HD, C-GZGQ http://mthobby.pcperfect.com/ch601 http://pages.infinit.net/mthobby ________________________________________________________________________________

Michel, I'd look for a fuel restriction in the line, gascolator, filter or anywhere ahead of the carb. This doesn't sound like an ignition, choke or spark type failure. A fuel restriction would allow you to get full throttle until the engine need gets ahead of the flow. Then it would starve itself at full setting after running full out for a short time.

Indeed that was my first impression. The symptom is exactly it. I did check the fuel flow right at the carb (disconnected the filter from the carb, put the hose towards a container and activated each fuel pump) and all was nice. I did check the float action and flow control of the float mechanism (as much as I could do it). I suspect a carburetor defect, but I'm wondering it this could be anything else. At the parking lot, I tested the operation with my three fuel pumps and my two ignition.. none would change anything in that bad engine behavior. ---------------------------- Michel Therrien CH601-HD, C-GZGQ http://mthobby.pcperfect.com/ch601 http://pages.infinit.net/mthobby --- On Thu, 5/27/10, Larry McFarland wrote: > From: Larry McFarland <larry(at)macsmachine.com> > Subject: Re: Zenith601-List: Bad takeoff, but still good landing > To: zenith601-list(at)matronics.com > Received: Thursday, May 27, 2010, 4:46 PM > --> Zenith601-List message posted > by: Larry McFarland > > > Michel, > I'd look for a fuel restriction in the line, gascolator, > filter or anywhere ahead of the carb.

Hi all Is it me or are other people confused with the Nose ribs section of the upgrade? I have the 3 nose ribs and following the Zenith photo guide becomes confusing here as their plane has the 4 nose ribs and so the photos don't match the plans. With nose rib No 1 it would have been great if they could have put a top down view as they do in nose rib 2. What happens to the row of rivet holes through the original spar web at the back of the spar? The nose rib 1 bracket is riveted on to the new .125 tho plate. Are we to rivet a plate over the old holes or just leave them open?? Can someone shoot a couple of pictures of this area Front and Back of what this nose rib 1 area is supposed to look like please. also I put it in, but why the bottom spar angle between 1 and 2 ribs? Have we had buckling in that area, and why not a full piece between 1 and 3 as you could still get an access panel hole if it was extended..

Hello all, I found the problem today. I had another Holley 5200 carb at home that I studied. I examined the fload mechanism. Then, I went back to the airport and opened the carb and this time, noticed that the movement of the float was very restrained. I then saw the issue. The floats activates a needle that seats in the bottom of a female piece. That piece was unscrewed! (see picture attached) So, the needle would seat and restrict the flow at low bowl fuel level. That was easilly repared. I tested my engine on the ground, holding it between 4600 and 4900 rpm with no mis or anything like that.... so, I'll fly it may be tomorrow. It is a bit frightening to see how we depend on so small things when we fly. An annual inspection would not reveal this type of problem. Thanks all who provided ideas of what to look for. ________________________________________________________________________________

Evening List, a quick couple of questions regarding the main spar carry through piece: Firstly, after having installed all the various new pieces on the spar carry through I was trial fitting it onto the cabin floor. Obviously the assembly is a bit wider than before to accommodate the thicker spar root. Ultimately when I cleco in the aft set of holes to the cabin floor I had a quick look at the forward set to see where they fall in relation to the holes forward holes. Basically the new forward holes will "clip" the old forward holes. Is this correct as it seems messy and makes me question a) whether I am doing it correctly and b) whether this is structurally ok? Secondly, after having trial fitted the spar carry through together I tried to push my centre punch through a couple of the holes to test alignment (with the holes on the other web). The two set of holes do not seem perfectly aligned. Did anyone else encounter this and if so what was the solution? FYI the holes on each web are very tight as I was concerned about the comments on the list about loose fittings etc. Should the spar holes accept the bolt dropping in or should it be tapped in with a rubber mallet or the like. Any advice in regards to either question would be much appreciated and apologies if anyone has already raised and answered the above questions.

Hi James, I haven't made it that far yet, but I have started thinking about it a little. The side skin will be a problem unless we do something to replace the skin around the carry-through. This is not as bad as it sounds since the new uprights are attached to both longerons instead of just the bottom one as in the original design. That makes the skin question a little bit less important. Perhaps some sort of patch over the old holes would solve that problem - either with or without removing the old skin around this area. I don't have any ideas about the alignment question. Part of this problem is the fact the front part of the fuselage "Floats" compared to the rear part until the carry-through is fastened in place.

I was working on the same thing today. I talked to Roger (ZAC) this morning about the same thing. Since I had not drilled the front flange yet I laid out a complete to line of holes half way between to old holes. Roger said just leave the old holes empty. With the spar out, we measured and pilot drilled the new line through the floor. Then with the spar in place we back drilled up through the floor and spar. It lined up well. So far as holes in the side skins, the "T" stiffener will cover all visible holes along the uprights. -------- BK Johnson Zodiac 601XL N601BK (reserved) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=299694#299694 ________________________________________________________________________________

Thanks wa7dvd. That seems to be a solution as I think that the upgrade manual suggests drilling through the existing holes in the forward flange of the spar which will clip the old cabin floor holes. I note that in one of the upgrade videos you can see that their clecos are squint because of this. Is there sufficient edge distance between the old and new holes in your method?

Hi Paul, I was considering "extending" the T section on the side of the fuselage downwards purely for aesthetic reasons. This would allow both covering all of the old forward upright holes and allowing you to cleanly recut the hole for the spar carry through to match the new upgraded dimensions. Probably lots of work to get a nice fit though. j [Rolling Eyes] [Rolling Eyes] -------- Cell +27 83 675 0815 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=299699#299699 ________________________________________________________________________________

Bruce - thanks for making the call to ZAC in the rivet holes thru that forward bottom doubler on the center spar. I unfortunately already backdrilled these so will need to add additional rivet holes to miss the holes in the fuse floor. On a related topic .. did anyone notice that the center spar doublers were shipped at length 945 when the ZAC upgrade plans call for a length of 940 on all the doublers. I just finished drilling and deburring all the doublers and wondering if I will need to trim these to avoid interference with the front and aft uprights? Someone who has already clecoed their center spar parts together and tested for clearance may already know the answer. Thanks!

Hi James I am far from taking my center spar apart, but I have been thinking about that alignment problem for a while. It seems to me that the best thing would be to actually bolt both wing spars to the two sides of the center spar before riveting the two sides together. That may be overkill, however. At a minimum, I think I'd want to put all 12 bolts in place on the center spar, with appropriate spacers between the top and bottom middle bolts, before I drilled the new doubler that will tie the tops of the center spar together. They must line up, and the holes must be tight. Since the holes are already drilled, they holes must be aligned before the two sides of the spar are drilled and riveted together. However, I haven't even looked at the instructions for upgrading the center spar, and it may be covered there. Let us know how you resolve this. Terry >Thanks wa7dvd.

Hi Terry, Good to hear from you again. The problem is that even without the actual wing spars in place I can see that the alignment is very slightly off on the outside bolt holes only. If I turn a wing spar bolt it twists into place (probably exerting some pressure on the thread but if i use a 5/16 transfer punch (ie. an object with straight sides it will not fit easily as it clips (very slightly) the edge of the web on the far side's bolt hole). Oddly, the other in board bolt holes seem to be, in general, well aligned. I note that the bolt holes were drilled by Zenith (ie. this was a kit not plans built) and the only modification I have made is in accordance with the upgrades to the carry through spar. I am very reluctant to ream the holes any further as on each web individually I have a nice fit (very) fit...especially after all the incidents and conversations on the forum. Any help would be appreciated. Has anyone had this problem?

Hi Chris I used the info from Zenair's construction standard CS#407, which says: >Drag torque. Run the nut down to near contact with the washer and check >the friction drag torque required to turn the nut. Add the drag torque to >the desired torque. This is referred to as the final torque which should >register on the indicator or setting on the torque wrench. And, as you note, CS#407 specifies 20-25 in-lbs for AN3's with AN365 nuts. The problem is, I do not see any way to measure the drag torque with a "click" type torque wrench. So I chose a "beam" type wrench, the Park TW-1, IIRC. It is actually sold as a bike tool, ~$40 USD. With my bolts, nuts, and wrench, I measure a drag torque of ~4 in-lb, so I torqued my AN3 to between 25 and 30 in-lb. That nut and bolt seem to be plenty tight to me. Perhaps your click wrench is not accurate in the low in-lb ranges. Terry >people >what torque are you doing these little nuts up to with the .125 th spar plate? >on the AC43-13B it talks about 25"lb.

Subject: Upgrade Tools list on Matronics Wiki
I am working my 601XL upgrade. A critical piece of information that I have not found in the Zenair upgrade dwgs and the Photo Assembly Guides is a list of the tools needed to perform the upgrades. I have been buying tools that I think will be useful. Some of them have been vital to my work. Others have been a waste of money, at least for the upgrade. I think that a tool list would be useful for upgraders, so I put together an Excel worksheet summarizing my experience with the tools I've purchased, good and bad. I've included my personal rating of each tool, as well as, cost and ordering links. I think that the Matronics Wiki provides an excellent vehicle to share this information with the 601XL/650 community, because a Wiki lends itself to editing--both revisions and additions--so any of you can weigh in with your experience. If you've discovered a really good tool, add it to the list. If I've panned some tool that you found useful--or vice versa, change the rating. If you decide to edit the information, thank you, and be sure to add your initials to the contributor's list. If you do edit the Wiki, you might post a note with that information to the Matronics lists. The link to the Wiki is: http://www.matronics.com/wiki/index.php/Zenith#601XL.2F650_Upgrade_of_December_2009 I tried to add structure for adding in upgrade tips and tricks, for those who would like to share your discoveries.

Terry, Check Jake Reyna's blog on the Zenith.aero forum. Jake has a procedure and pictures of how he handled the placement of the holes in the center spar front flange. Basically, he used the floor doubler as a template and drilled new holes between the existing holes. That gave him solid material all the way through the bottom doubler, floor, and spar flange. No dealing with having to drill through half misaligned holes in the floor. You drill through the bottom doubler and front spar flange on the work table, then only have to back drill through the floor with the doubler (template) in position under the fuselage. I did mine that way and I'm satisfied with it.

The list looks good for starters with differences being mostly personal preference. I'd suggest using a 4x rivet gun. The 3x will probably work ok, but the extra punch of the 4x makes setting the #6 rivets quicker and less tendency for the gun to bounce. I like to use an adjustable size reamer rather than a single step fixed size. With the adjustable, I can sneak up on the hole size to give me a better fit to the bolt whatever small size difference it may have from it's nominal size. I could add; Lathe, milling machine, TIG welder, metal brake, metal shear, more rivets, longer #6 rivets than what Zenith sends. Mind reading course to help with interpreting the drawings and instructions. -------- Louis W.

I did the same as Paul. Don't use a soft wood as it will just tend to splinter. Carve it so it fits the profile of the opening as close as possible. You might try tapping the rim with a wood or rubber mallet and slip some oil between the skin and the lip to remove some of the friction. It can be a real son-of-a-gun to get off but be persistent. I just had to remove one as part of my wing modification and know what you are facing. If it originally turned in really hard you may have a problem with bad threads. I had one like that and had to cut the cap flange out and buy a replacement. I then borrowed the "big tap" from Zenith to clean out the threads in both tanks and when I installed the new one I used teflon paste on the threads. Good luck!

Subject: Aileron bellcrank wear?
From: "Tim Juhl" <juhl(at)avci.net>
Date: Jun 14, 2010
This question is for those who've opened their wings up for modification after putting some flight hours on their aircraft. Has anyone noticed any wear in the holes where the control cables attach to the aileron bellcrank? Since there is tension on the cables I wonder whether the hole is elongating in the direction of the tension being applied. If so, it would seem to me that this would be a good place to install a bushing. I own a taildragger and one of the things you watch for is that the holes on the rudder horn where the tailwheel springs attach will often wear in such a manner. The rudder horn is half-inch thick aluminum with steel springs attached - much beefier than the bellcrank. The springs are under tension, just like the control cables and over time the steel cuts into the softer aluminum. Comments?

Peter, When you get it apart, I recommend when you reassemble coat the threads with fuel lube (http://www.aircraftspruce.com/catalog/cspages/ezturnlube.php) to seal the filler neck. I used this last time I installed the filler neck and it came right out when opening the wing for the upgrade. Fuel lube does not harden and provides a great seal.

Boy do I know about that part coming out hard. When we did the CZAW teardown one tank was difficult to remove the flange but it was a one man job and wood did the trick. The second one was a three man 1.5 hour job using a steel insert to turn the flange. We used penetrating oil and worked the flange both ways and gradually it came out. The fit was not good and they used some type of hardening sealer on the threads. Used the Big tap from Zenith to chase the threads on both tanks and used Fuelube to seal the threads. P.S. I ran a low pressure test on my tank the other day with only fuelube on the finger tight threads of both the finger screen and the filler tube, RESULTS: no leaks. Low pressure test is tying a latex glove over the vent tube, inflate the glove and seal it up, wait to see if the glove deflates. -------- Ron Lendon, Clinton Township, MI WW Corvair with Roy's Garage 5th bearing Zodiac XL, ScrapBuilder ;-) http://www.mykitlog.com/rlendon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=301374#301374 ________________________________________________________________________________

I'm getting ready to install the aileron balance in my right aileron.

This would result in the tube not being at a right angle to the rear spar. In my view, this would result in requiring a wider hole in the spar to accommodate the lateral movement of the tube when the aileron is deflected. I also believe there was an earlier discussion of the need to bend the tube inwards to clear the wingtip rivet line. I wonder how others have dealt with this issue. I'm consideringL 1.) installing the ribs supporting the tube so as to place the tube at a right angle to the spar, & 2.)

Subject: Rivet Removal
My two cents on removing solid spar rivets: I'm drilling the heads with a #20 drill down to about even with the sheet metal and then using a Stanley wood chisel to remove the head. Three or four hits with my little hammer and the head goes flying. Barely even scuffs the surface of the sheet metal. When I'm all done the chisel won't be worth much, but it was pretty cheap. Getting the rest of the rivet out I use a small pin punch and whack it a few times.

Subject: Re: Aileron balance install
Tim, I did two things. First I did not keep the arms parallel to the ribs. I shifted them just enough so they would be far enough away from the other structures so no interference was possible (including the metal plates). I allowed about 1 inch from the end of the tube to any other part. Secondly, I filled about 7 inches of the end of the square tube with lead. It melts at about 600-700F and alumimum is melts at around 1200F so as long as one keeps the lead at just above the melting point it works. I stuffed and tamped aluminim foil into the tube to act as a plug to define the area to be filled. A heat gun was used to pre-heat the tube a bit so the lead would flow all the way to the plug. The lead was melted using a 1500W hot plate with the lead in a metal coffee can and with a larger metal can inverted over that to keep the heat in. It took about 40 minutes to get the lead all melted. You will need about 1.5 pounds of lead for each side. I started with 5 pounds total and that made it easy to pour. Doing this I only needed two steel plates to balance. This allowed one to use the specified holes by turning the aileron vertical to insert the tube in the hole with the balance plates on. This way the aileron can be removed in the future.

The one I just did I just made square to the hinge line and picked up two existing rivets for the new rib rivet lines. I checked clearance with a large carpenters square from the center of one rivet and wouldn't ya know, the next rivet was 40mm away, ( just perfect for the rib lines) . It was very easy to draw those lines around the aileron skin using a square. Once the lines were drawn just mark and drill the end holes, and rivet fan for the 5 rivets on the end, and 8 rivets top and bottom. -------- Ron Lendon, Clinton Township, MI WW Corvair with Roy's Garage 5th bearing Zodiac XL, ScrapBuilder ;-) http://www.mykitlog.com/rlendon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=301722#301722 Attachments: http://forums.matronics.com//files/zu_108a_210.jpg http://forums.matronics.com//files/zu_104_442.jpg ________________________________________________________________________________

I did mine kind of like Ron did, except I "split the difference" between the rivet lines. http://www.zenith.aero/photo/aileron-balance-ribs Had plenty of clearance, and I didn't have to mess around with bending the arm. Having 20/20 hindsight, if I could do it all over again I'd have put the aileron trim on the right wing instead of the left. Between that and the counter weight, the left wing is starting to get kind of heavy way out there by the tip, and since the pilot sits on the left side anyway, it would have been nicer to have all that weight on the other side to balance things out better. I also like the idea of filling the end of that tube with lead and keeping the whole thing "skinny" so the aileron could be removed in the future if need be. I didn't do that, and hope I don't come to regret that. - Pat -------- Patrick XL/650/Corvair N63PZ (reserved) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=301742#301742 ________________________________________________________________________________

This means force applied to the control stick doesn't require much movement of the ailerons to produce roll torque. It also means the ailerons work quite well all the down to stall speed where most spam cans lose nearly all control effect. I believe it is the geometry and size of the ailerons that makes them feel so stiff in flight rather than any drag in the control cables. Good luck, Paul XL fighting main spar rivet removal for the upgrade. -----Original Message----- From: owner-zenith601-list-server(at)matronics.com [mailto:owner-zenith601-list-server(at)matronics.com] On Behalf Of Terry Phillips Sent: Sunday, June 20, 2010 8:38 PM Subject: Re: Zenith601-List: Re: Aileron bellcrank wear?

Hi Terry, I do have a drawing I made just to see if it would work. I Printed out a full size example and cut it out from cardboard. I can't remember if any slight changes were done when I cut it from aluminum. I don't think so. The drawing was done in Solidworks. I exported a .jpg file of the drawing so the quality isn't so great. The bronze bushings are Aircraft Spruce P/N FF303-01. Look under Hardware, Bushings. They are $0.19 each. Drill the bushing hole in the bellcrank slightly undersize and press in the bushing. The bellcrank bearing is Aircraft Spruce P/N BC4W10 (AN218-4). Look under Airframe parts, Bearings. It costs $18.95. This bellcrank doesn't require any changes to the normal mount and the geometry is the same as the Zenith bellcrank. Use a washer on top and bottom of the bearing to insure the bearing housing doesn't rub on the support when you tighten the bolt. I don't know how much drag the fairleads would add to the aileron movement. The cables don't move very far to give full travel. It'll be something I'll check when I connect the controls. BTW, the SS rivets work great. Thanks Louie Terry Phillips wrote: > Louie > > You are a true craftsman. You new bellcrank is a work of art. Do you have a > drawing of your design?

Lee, The drawing calls for rivets on a 20 mm pitch so some new holes need to be made anyway. I did all new holes with the old holes half way way between the new ones and offset enough so as to provide sufficient hole to hole spacing. If the old holes in yours are positioned such that there is no room to provide sufficient spacing, then ZAC will have to come up with something.

If anyone is interested, I have a rivet squeezer along with the required yokes and dies to put in the solid #6 rivets in the main spar and the #5 solid rivets along the joint on the top of the center spar connecting the two half's (the 20 mm pitch rivets). The yokes are not big enough to do the solid rivets on the center spar on the vertical surfaces. I found the latter to be the easiest ones to put in with a rivet gun anyway. I am willing to lend it to others or even sell the bunch. I have about $450 tied up in all the parts. It might be a good tool for a club. It will do up to #6 rivets. -- Mark Hubelbank NorthEast Monitoring 2 Clock Tower Place Suite 555 Maynard, MA, 01754 - USA mhubel(at)nemon.com 978-443-3955 ________________________________________________________________________________

>From Caleb: > > Hi Lee, > A doubler, such as this, is the proper way to repair ovalled holes. That is one of the reasons for having the part installed at all. When you mess up a hole and its ovalled, you put a doubler over the hole and rivet it to the web as well as the flange. This will unload the ovalled hole and provide an alternate load path (the load now goes through the doubler) into the web. In this case the doubler is heavier than the flange material because we want to add strength beyond the normal spar. The ovalled holes are a consequence of spacing the front and rear halves further apart 1/8" but this has been accounted for in the development of the upgrade package. You don't need to worry about ovalling those holes, just so long as the holes in the doublers are all round. > Read this topic online here: http://forums.matronics.com/viewtopic.php?p=301961#301961 ________________________________________________________________________________

Hi Tim, Just a guess . . . I would think a proper (i.e. thin) paint job would weigh considerably less than one of those steel weights.

Subject: Re: Aileron bellcrank wear?
Hi Paul I do not have personal experience on the 601XL control harmony problem. My total time in 601XL is a 30 minute flight in the factory demo plane. I am just reacting to various posts on line that suggest that control harmony is not good on the 601XL. I think that it is likely that high friction in the aileron controls were an important factor in the pre-upgrade design to avoid aileron flutter. Normal design practice is to eliminate flutter with counterbalanced control surfaces. (If you look at almost any certificated airplanes with aluminum skinned ailerons, you will find counterbalances.) If one can count on the aileron counterbalances to eliminate flutter in the 601XL, then one should be able to replace the aileron fairleads with pulleys w/o introducing a new risk of aileron flutter. Since the elevator and rudder are not counterbalanced, I would not consider replacing the fairleads in those control links. If you are correct that the high forces for roll control reported for the 601XL are simply due to the geometry and size of the ailerons, then installing pulleys will not improve the control harmony. However, if friction in the control links proves to be significant then pulleys might make a useful difference. I'm a long way from building my fuselage, so my ultimate decision on this item is not imminent. Some other builders have replaced the control cables with push-pull rods. I'm very curious if any one has replaced the aileron fairleads with pulleys.

Michel, The bushing was made as a press fit in the large plate. The bolt secures center within the bushing and was easy to lubricate by greasing the bolt on assembly. The upper and lower plates held to center by the bolt are strong enough to not allow the bolt to rotate in them. The actual rotation forces are borne by the largest surfaces of the bolt and inside the bushing. The top and bottom bushing surfaces are not strained at all in flight. Wear on my bolt occurred because it was not tight and locked to allow no pivot within the upper and lower plates. The bolt now rotates with the rudder and the bushing is fixed by its fit in the plate. I had to make 4 bushings to get it right. The bottom plate holds the rudder at elevation as well so that the top bushing isn't doing all the lifting. If the bushing were allowed to rotate in the top and bottom plates, I believe wear would be a significant issue at the top pivot assembly. Doubt bronze would be as good in holding a press fit and that's why I made mine of steel.

Subject: How much paint?
Date: Jul 03, 2010
The list has been fairly quiet lately, so I thought I'd ask one of those questions that must be burning in everyone's mind: How much paint (in gallons) does it take to do a 601XL? I realize I also need primer, thinner, etchant, etc, but if I knew how much paint some of you needed, I might be able to factor those other numbers. Of course, if someone happens to have those at hand, I wouldn't mind real numbers there, either. -- ======================================= Jim B.

I used a white undercoat on the entire airplane. It seems like it took 5-6 qts. Kirker is a great cost / quality compromise. http://www.autobodytoolmart.com/ultra-glo-acrylic-urethane-enamel-paints-c-895.aspx There are more expensive paints out there and perhaps they come with higher quality but in the end you'll end up doing it a 2nd time due to upgrades. At least that has been my experience.

Hi Tim, I am at the exact stage you are discussing, but I have taken a different path. I decided to use bolts instead of rivets when installing the new spar cap angle. I will use AN4 bolts in the inner section where the original 3/6 rivets are used and AN3 bolts where the smaller rivets are used. I already have the correct drill and reamer for the AN4 bolts, but I have not yet acquired a reamer for the smaller ones. I ordered it yesterday, but A/S seems to have them on back order. It is necessary to move up to AN4 bolts because the original holes used for the 3/16 rivets are too large for AN3 bolts. They would just rattle around in the oversized holes. The smaller holes, 5/32, don't have a corresponding bolt size so I will increase them to 3/16 for use with AN3 bolts. I realize the bolts are heavier than aluminum rivets, but I feel my skills are adequate to install the bolts and insufficient to install the huge rivets. If I had your exact situation I would merely order the required rivet sizes from Aircraft Spruce or a similar vendor to meet my needs. I was surprised the upgrade kit had exactly the required number of solid rivets when the first time builders have never used solid rivets before. This compares unfavorably with the supply of A4 and A5 Avex rivets which seems to be an ample supply measured by the pound rather than the exact number that matches the number of expected holes. I know I have an attitude problem when it comes to Zenith and the Heintz family, but I would not depend on them being around much longer to complete my plane. I am glad we got a "Blessed" design upgrade, but since we still have no clue what the actual problem is that led to all the deaths I have very little confidence the upgrade will fix the real (but still unknown) problem. I will just do my best to install the upgrade and then take my plane into phase I testing. I still have not decided whether to take it into phase II or not.

Hi Tim The 3/16" solid rivets supplied in my upgrade kit were all AN470AD-6-14's and AN470AD-6-10's.I thought that AN470AD-6-14's were too short for the spar cap-spar web-spar cap doubler-extrusion joint. So, for that joint, I used AN470AD-6-16 that I had purchased from Spruce. I used the AN470AD-6-14's supplied by Zenair for the outboard section beyond the end of the spar cap doubler where the joint is 1/4" thinner. My Avery rivet length gage showed the -16's being ~1/32" too long and the -14's being ~3/32" too short. My interpretation of the plans was to replace the 5/32" rivets in the spar cap beyond the spar cap doubler with 3/16" rivets, except for the most outboard one which was replaced with a 3/16" AN bolt. I was never able to develop what I considered adequate skills to set the 3/16" rivets with my 3X rivet gun. Fortunately, I was able to borrow what I call a "pounder" tool to set the rivets and it worked perfectly, so long as I didn't hit the spar with the hammer. It is possible that I would have been able to set Zenair's shorter rivets with my 3X gun, but I doubt that the shop heads would have met both the minimum diameter and minimum thickness specs. Like Paul, I found that the 3/16" rivet holes in my spar caps are too large diameter for AN3 bolts, so I bought AN4's to attach the spar root doubler plate. That's my next step.

I used a 4X gun and a 5lb bucking block of steel. The AN470AD-6-15's set just fine. The trick is to not pull or let off the trigger without having pressure (arm strong) against the factory head. The bucking bar just has to touch to shop head, you don't have to press hard with the bucking bar. Once you have set a few you can hear and feel when it is set right. The 3X gun wasn't doing a good job. There were a couple I had to remove and reset, the 4X gun expanded the rivets much better, the 3X gun rivets came out real easy, not so with the 4X gun, it took more work to get them out and that is a good thing here. All they sent me were the 15's and the 10's for the wing spars. They all finished within the Mil Specs. I think the reference to the 14's is an error in the print, call zenith or post to their zenith.aero site directly to Mathieu Heintz. -------- Ron Lendon, Clinton Township, MI WW Corvair with Roy's Garage 5th bearing Zodiac XL, ScrapBuilder ;-) http://www.mykitlog.com/rlendon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=303636#303636 ________________________________________________________________________________

Subject: stabilizer attachment
From: Carlos Sa <carlossa52(at)gmail.com>
Hello, all I am building the rear fuselage, and before committing to the position of parts, I decided to check how the stabilizer would align. Looks like I'll have to move it forward somewhat (2 or 3 cm), and perhaps add a little shim to the rear attachment, so the width looks ok. My question to the group is about edge distance: the (CH601-HD) construction manual (Edition 3, Jan 1995) says, in the "tail installation on the fuselage" section (page 26): "watch for a minimum edge distance of 13 mm to any edge." While the dimensions of 6F2-7 and -8 (6B3-3/4 on the XL) allow for this, 6T2-1 and 6T2-3 do not - or at least I don't see how. Therefore, I am assuming that the 13 mm statement refers to the HT attachment brackets only (6F2-7 / 8 on the 601-HD and 6B3-3 / 4 on the XL). I would appreciate the group's comments on this. Thanks in advance Carlos CH601-HD, plans ________________________________________________________________________________

Thanks for the info... I appreciate all your comments. I was planning on using a mix of rivets and bolts, assuming I can set the rivets OK with my 3x gun. I haven't a lot of experience riveting (took an EAA class) and plan to set up a practice jig to see how it goes. I did buy a 5 lb bucking bar which I understand should help. The features that attracted me to the XL in the first place haven't changed. My hope is that experience with the modified aircraft will allow all of us to fly our planes with confidence as long as we stay within the envelope, which is true of all aircraft. I didn't mean to rekindle old arguments but we all know that we'll have to wait for some time to pass to get our answers. Happy 4th of July!

A lot of folks get the base and foam done, then take them to an upholstery shop. I got seat covers at Pep Boys and made do. The foam came from Wicks, I think. The plywood base for the back was flat. The plywood base for the bottom was kerfed for bending and pressed into the seat pan. The wheels kept them pressed in tight while the epoxy coating set up to hold the shape. Let me know if you have questions. Jay ________________________________________________________________________________

Hmmm. All my photos had a .jpg extension, which is about as "valid" as yo u can get, So I don't know what the problem was. Jim, I will send them directly to you, OK?

I get individual e-mails and received 8 photos. I thought the tires went on the outside of the plane. :-) -- Craig _____ From: owner-zenith601-list-server(at)matronics.com [mailto:owner-zenith601-list-server(at)matronics.com] On Behalf Of jaybannist(at)cs.com Sent: Sunday, July 11, 2010 1:10 PM Subject: Zenith601-List: Re: Returned Mail: Re: Seats for my 601XL B Hmmm.

Second time around for seats for us. I had separate backs and seats made by a local auto upholstery shop. No plywood or anything else. Works fine. Cost was about $300. I made the side panels myself -- about $60 for material. Will send pix if you like.
