That is -- the "flat" edge of the leaf gear was shifted from the rear side to the front. I couldn't find any answer in the archives, and I'm wondering the same thing. I asked Nick in August, and he basically said it didn't matter -- that it would only affect the amount of back pressure on the stick needed to rotate. Seems to me that the 5" shift in the position of the mains would make quite a difference in the weight distribution among the wheels. With a relatively light Jab engine, my gut feeling is that having the mains rearward would be better, putting more weight on the nose. Or is it preferable to keep the nose light (ie, mains more fwd.)?? Any comments from you "completed and flying"??

If there is any hidden impact to this question, it would probably be in the overall CG location. In general, I think the further forward the CG the better the pitch stability and airspeed stability. Both of these would be positive contributions to safety and ease of flying. On the other hand moving the main gear back would give more tendency for the plane to straighten out on a less than perfect landing. That is because the CG would be further forward of the main gear. Finally, if Nick says it doesn't make much difference, then I must conclude that it doesn't make much difference.

In the end, it seems the only time this issue comes up in real flying is when doing power dives. For normal operations, it is maximum cruise speed that will be the fastest you go. If my conclusion above is true, then it is only "Hot dogging" that plays into the VNE value after you have a little margin over cruise speed. Once I figured that out, I lost nearly all interest in the specification of VNE.

Use a feeler gage strip if necessary and after you've deburred the last holes, vacuum or airblast the material out. They can cause you to pull a rivet and create a dink beside it. It's just better housekeeping to clean before you close.

You are supposed to fly your plane to a speed of 111% of Vne during phase I testing to establish the safe operting limits of the airframe. You work your way up to this speed gradually with a series of flights. If you are not willing to test fly the airplane beyond say 150 mph then your Vne technically should be set as 135 mph. I have established during testing that my Vne can be safely set at 180 mph for my airplane. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. do not archive > --> Zenith-List message posted by: Rico Voss > > I'm not planning to test my structural integrity by pushing > to VNE (especially if it's 180).

These represent changes in "Thinking" from one designer's home-built experimental creation to a group's notion of a safe Light Sport Airplane. If anything, the current version of the XL is more sturdy than it has ever been. The change in VNE may reflect a difference in thinking more than a new level of structural weakness.

Just like the bungee on the nose fork has no stop or "keeper" on the front. Not necessary. You will see when you install your elevator cables. There is plenty tension there and sliding the torque tube forward is an non-issue. For the flap hole - it can be moved to suit your installation. It is supposed to be slotted anyway so you will have to move and expand the slot as needed with the nylon insert. Good luck, Scott Laughlin www.cooknwithgas.com Paul Moore wrote: --> Zenith-List message posted by: "Paul Moore" 2 XL questions for those in the know: The torque rod for the control yoke has a stop ring on the end just in front of the front spar carry-through to keep the rod from exiting out the back of the bearings. It sure seems like there should be a second one to keep it from moving forward as well but nothing on the plans shows one. There are 4" to 5" of travel available there, unless the aileron and elevator cable tension is enough keep it pulled back tight. Did anyone add a second ring either behind the front bearing or behind the rear one? On the flap actuator torque rod bearings, there is only one way the big bearing holes can be positioned in the bearing while honoring the edge distances, etc. --------------------------------- ________________________________ Message 14 ____________________________________ Time: 08:06:13 AM PST US Subject: Zenith-List: Re: accurate performance numbers From: Grant Corriveau --> Zenith-List message posted by: Grant Corriveau I flew a friend's XL with the Rotax 912s and averaged an honest 130+ mph over a 6 hour day approximately.

Here's the one I made for my wing tanks: http://www.cooknwithgas.com/3_5_03_SenderParts.JPG I just match-drilled it and threaded the holes for machine screws. It really secure and seals well with the gasket. If you already have a 1/8" backing plated welded to the tank, I think it would be prudent to drill the holes and tap them for machine screws and you would be in business.

Some of us decided to tackle the paint ourselfves and came out pretty good. I get compliments on my garage paint job all the time. I thought it would be hard but it's not. All of the work is in the prep of the metal and you can expect a high-price from a shop because of this. If you do it yourself you can save big $$. I reckon my paint job was less than $700 in materials (used good paint). If you want more info there is a really good article on painting on www.ch601.org that explains pretty much everything you need to know.

No, it is not obvious as I think everybody who has been there will tell you. When you actually start riveting is up to you. In my case it was when I ran out of clecos. Remove, debur, clean, prime and rivet what you can and leave the rest in clecos until you have to move on or run out of clecos again. If I remember correctly, I riveted the rear fuselage and sides, then assembled the firewall and floor and riveted this part. Then I joined them together and riveted. The top longerons were next and stayed cleco'd for a long time while fitting the sides. The rear wing attachment was extremely time consuming for me. I was really careful.

However cane across an untouched XL tail kit, plans, etc to start and couldn't turn down. My first question for the group: I purchased the plans, manuals, a complete tail kit (new, less than a month old from the factory) from the original owner. What do I need from that owner to transfer the ownership (serial number) for Zenith, Mine, and of the course the FAA records. I've contacted Zenith also in regards to this question but I thought I would ask here also. Any help would be appreciated. Look for a construction log online within a month or two.

I could have easily made 3 more sets of ribs with them. Perhaps they're made too good. 1/8-inch aluminum seems like a pain to me. Try the plywood, it's faster, cheaper and will probably do what you need. If it doesn't you can always back into the aluminum.

I did exactly that last night. I was to lazy to get the vacuum cleaner, so I turned the stabilizer around, lifted it up and shock vigorously to get the crud out. Most of it landed on my head (first time baldness turned out to be an advantage) and the loose top skin flapped out and hit me on the nose with the edge. Now I don't have to emphasise the cutting qualities of the thin sheets, enough to say it was painfull, bloody and embarrassing. At least the cut is very straight across the nose... My tip: use a vacuum cleaner :-) In regards to the control torque tube, the tube is held back firmly by the cable tension. If the cable ever breaks the second bearing is not going to do much good I am afraid. You will have to fly the plane with electric trim then, works quite well and I would recommend to practice that on a regular basis.

I would guess a bill of sale and possibly the original Zenith invoice to the first owner would be enough paperwork to satisfy even the FAA. Of course, it is important that Zenith recognizes you as the owner of that serial number so they provide proper support for you. I think you will be happy with the XL. It offers higher performance than the HDS and compatibility with the new Light Sport Aircraft criteria. Rumor has it it has nicer flying traits than the HDS as well.

ALUA?( I'm Canadian and still can't figure out which is which yet) that will be used for flight instruction will be an update on our plans. SO if you have ever been in a circuit behind several student all learning about the term wheel barrowing then you can understand the need for Zenith to beef up the stiffener. For the rest of us the old version is just fine and has been used trouble free since the start of the Zodiac series. Not the same can be said for the 701. Changes were necessary on that model, since it was originally designed for a 503 2 stroke engine and people were hanging Subaru's and 912's. Therefore, changes were necessary to accommodate the heavier engines. So end result change is not necessary for the majority of us and it would likely just add unwanted weight. But If you plan or have a history of 1 wheel landings then by all means add the stiffeners it won't hurt anything.

I am just about where you are. I riveted the bottom first, then the sides. I am now working on the Firewall, and plan on riveting this when done. Something to note. ZAC beefed up the top stiffener on the firewall on their latest revision. My kit is version 2 and doesn't have this reinforcement. It looks like this is to react nose gear loads. I decided to make is similar to the new version. http://www.zodiacxl.com/Forward%20Fusealage.htm Scott, Really good advice. I have been following your site in my build. I certainly agree that there is always "one more thing to deal with". I amaze at the creative ways I have mess things up. I have come to a realization. It is usually much easier to fix than you originally think. It is good to know that we are all just learning.

Just like the bungee on the nose fork has no stop or "keeper" on the front. Not necessary. You will see when you install your elevator cables. There is plenty tension there and sliding the torque tube forward is an non-issue. For the flap hole - it can be moved to suit your installation. It is supposed to be slotted anyway so you will have to move and expand the slot as needed with the nylon insert. Good luck, Scott Laughlin www.cooknwithgas.com Paul Moore wrote: --> Zenith-List message posted by: "Paul Moore" 2 XL questions for those in the know: The torque rod for the control yoke has a stop ring on the end just in front of the front spar carry-through to keep the rod from exiting out the back of the bearings. It sure seems like there should be a second one to keep it from moving forward as well but nothing on the plans shows one. There are 4" to 5" of travel available there, unless the aileron and elevator cable tension is enough keep it pulled back tight. Did anyone add a second ring either behind the front bearing or behind the rear one? On the flap actuator torque rod bearings, there is only one way the big bearing holes can be positioned in the bearing while honoring the edge distances, etc. --------------------------------- ________________________________ Message 54 ____________________________________ Time: 08:16:13 PM PST US From: Jim and Lucy Subject: Re: Zenith-List: subaru manifold --> Zenith-List message posted by: Jim and Lucy At 10:22 PM 10/31/2005, you wrote: >--> Zenith-List message posted by: > >Can anyone tell me where to find a Subaru conversion intake manifold to >fit a bing carburetor?
