Why can't all suppliers have such great, interactive online web pages! For example - if you check out the fuel check valve page, as you click the radio button choices for types of ends on the valve, the diagram automatically changes to show what that looks like!

I made small adjustments by rigging the neutral position of both ailerons. I adjusted them both 'downwards' by the same small amount - a degree or so at a time... then checked the flight results until I liked the attitude. Theoretically this may reduce cruise speed by a knot or two. I was careful to ensure that the aileron push/pull rods always had at least the minimum number of threads inside the end attachments; and that the ailerons still have full travel in both directions. -- Grant Corriveau C-GHTF / HDS / CAM100 ________________________________ Message 4 _____________________________________ Time: 05:31:03 AM PST US Subject: Zenith-List: Who do we believe?

In building this aircraft, I have been confronted with the dilemma of 'who to believe' many times, as different bits of conflicting advice were passed back and forth. Just one rather obvious example from my own experience: I was told by my final inspector (Canadian regs), that the air inlet/carb heat tube was automotive grade tubing from Canadian Tire and should be replaced with an aviation grade SCAT tube. I thought to myself: "But the engine manufacturer wouldn't have installed this thing if they didn't know already that it works fine... - right-?" Well, in the first two hours that automotive grade tube began flaking to pieces from the heat and vibrations. I'm thankful that none of the bits found their way into the carb. Also, it took a long time for Zenair to give up on their 'pet' flip/flop canopy design and produce the XL with the rear opener type. So far I haven't heard of any of this new design inadvertantly opening and departing the airplane. On the other hand, there are hundreds of Zenair planes out there flying successfully DESPITE the worst mods you can imagine we builders inflicting on the basic design! Overall it has proven its worth 'as designed' many many times. In the final analysis, YOU the builder will be responsible to gather all the information, THEN sift out the pet peeves, preferences, and pontifications from the hard facts, and build it accordingly. Eventually it will be your butt strapped to the resulting airplane. You'll want to be confident in whatever choices you've made. Happy flying. -- Grant Corriveau C-GHTF / HDS / CAM100 ________________________________ Message 5 _____________________________________ Time: 06:08:26 AM PST US From: Don Mountain Subject: Zenith-List: Tech Counselor --> Zenith-List message posted by: Don Mountain I have been working on my 601 XL for about 4 months now, and finished all the tail pieces, ailerons, flaps, and wing framing.

The change may have other consequences that are obscure to you. Call Nick and talk to him before making such a material change or at least ask the Tech Counselor to provide the numbers that show design deficiency.

Some are A&P'S, others are just very good at building. An EAA Tech Counselor cannot charge for his or her time. It also looks good when your DAR is inspecting your plane. ----- Original Message ----- From: "Don Mountain" Subject: Zenith-List: Tech Counselor I read some recent > messages about "tech counselors" here.

Not many are experts in design or engineering, but do have an intuitive eye and generally good knowlege of what is correct or not in aircraft construction. They donate their time to come and provide an extra set of eyes for the builder during the construction process. The intent by EAA is to provide assist to the builder and improve the safety record of homebuilt aircraft. They do not charge for their time and they are found by contacting the nearest EAA Chapter to arrange such a visit. Their qualifications are general and non specific, but each chapter has a couple of Tech Counselors that are "expert" in welding or engines, sheet metal or fabric etc. On most design or build decisions, the designer should be contacted when something is questioned. Zenith was most helpful during the build of my project and I had three visits by our tech counselors that assisted obtaining insurance on my plane before it flew.

Goodings" Subject: Zenith-List: Re: Zenith-List Digest: Intermittent Radio Noise --> Zenith-List message posted by: "John M. Goodings" A couple of weeks ago, I reported intermittent radio noise in our headsets on transmit and receive from the tower. We seem to have gotten rid of the problem, although the solution is not clear-cut. We removed the 25-pin computer plug from the back of the NAT intercom, wiped the silicone grease around a bit, put the plug on and off about 3 times, and then put the screws back. A more likely cure was the BNC cable plug onto a BNC elbow plugged into the BNC socket on the bottom of the Comant VHF antenna mounted centrally on the top skin of our Zodiac HD. These Amphenol BNC plugs/sockets came silver-plated, and were a bit tarnished. I wiped them, put silicone grease on them, and then plugged them on and off about 3 times. There are a couple of points of interest here. The base of the VHF antenna must be grounded to the top skin; it was, by the 4 mounting screws. If it is not grounded here, I am told the cable back to the radio becomes part of the antenna, and radiates VHF inside the aircraft with inevitably bad results. A rubber gasket is supplied, and was installed between the antenna base and the top skin; its purpose is to let the antenna flex a bit in the wind without putting a crease in the top skin (it is only 0.016" Al in the HD; I also added a doubler plate of 0.025" AL). Some people firmly believe this gasket must be removed and thrown out. I don't buy this, provided it doesn't interfere with the antenna base grounding to the top skin. The difficult part in finding this problem was the facts that (a) it almost always happened in the air, not on the ground, and (b) it seemed to happen on hot humid days, not cool dry ones. Perhaps the top skin/antenna flexes a little bit differently in the air, because of wind resistance, due to thermal expansion??? The reason for putting this down to the List is: beware of tarnished contacts. I am a great believer in silicone grease on electrical contacts to prevent corrosion leading to a bad contact. This grease, although itself an insulator, never seems to cause a bad contact, but serves to prevent them. I give my thanks to Zed Smith for his comments to the List in response to my earlier "cry for help"!

If I understood them correctly my engine should be on the next boat over from Australia and they thought they would be able to ship to me at the end of July or beginning of August. I also asked them to go ahead and ship my FWF as soon as they had a complete kit together so I can get started on that. I have talked to Pete from Jabiru USA for the past 2 years at Sun n Fun and Oshkosh and he always seemed straight forward with me. Also, there's a Jabiru class 2-3 and 4-5 August in Shelbyville, TN. I'm registered for the 2-3 class. Get all of your orders in now for timely shipment. Best regards.
