What would be the possibility and approx.cost to ship to North Carolina Do you have any good pic. of the construction Thanks Don ----- Original Message ----- From: kaimaki@comcast.net To: zenith601-list@matronics.com ; zenith601-list@matronics.com Sent: Saturday, November 28, 2009 12:49 PM Subject: Zenith601-List: Must sell 601 XL wing and tail kit - leaving the country I am leaving the country in the not too distant future and would like to find a good home for the completed tail kit and the partially completed wing kit of a 601 XL. The wing kit includes: - standard tanks - wing lockers - landing lights - complete fuel kit The wing kit completion status: - aileron incl. full length trim tab completed - flaps completed - left wing started I also incl. all the tools and supplies and my 12 x 4 foot table in the sale. I am not sure what a fair asking price is so I decided to consider any offer above $2000. I would like to sell everything together but I will consider offers for parts of the kits. Please contact me off-line at kaimaki@comcast.net for further information and to make an offer. Thank you.

Please e-mail me off list. I have removed the ailerons primarily to keep from flying it and found no damage or loose rivets. Does anyone know if the upgrade kits are shipping for the E-AB builders?

Manlove" Subject: Zenith601-List: I don't understand... I am having a hard time understanding why anyone would even consider NOT fixing their 601/650, if they built it themselves. If you live up north, it'll be a good winter project. Any home-built kit should be flown by carefully by the seat of your pants anyway... and adding hours will add confidence. With all of the different "certified" aircraft that have crashed and burned, I believe Zenith is doing this for complete redundancy, not because the aircraft is inherently badly designed. Look at the THOUSANDS of hours on these 601's, including some very hard flying by some very good pilots. without incident. I can understand the desire for redundancy. But I also understand that being careful and thorough and knowing what you are doing is more important. I just re-read "Stick and Rudder" by Wolfgang Langenwieshe, and there is a chapter in there by an NTSB accident investigator. More novice pilots have died trying to circle their house and do "wing salutes" than almost every other category. Add some too-sloppy control cables and a slow speed, tight turn and I don't care if you're flying a brand-new anything, you are risking your life. If anyone wants to give me their 601, I'll be happy to come and pick it up. I have a nice trailer. CH750/Corvair, in the works. ________________________________ Message 5 _____________________________________ Time: 05:55:07 PM PST US Subject: Zenith601-List: Re: I don't understand... From: "mhubel" While I can see your point, to some degree I can understand. Some of us decided to build a plane once with no intention of ever doing it again. It was fun once. Then it was time to fly it. This "upgrade" is a very significant fraction of the original build time. I had doubts myself. Had it not been for the two others who have offered to help do the modifications, my enthusiasm to do this would be very low. -------- Mark Hubelbank N708HU CH601XL Jabiru 3300 Rotec TBI 40 carb Sensenich ground adj prop. 41 hr TAF Read this topic online here: http://forums.matronics.com/viewtopic.php?p=276087#276087 ________________________________ Message 6 _____________________________________ Time: 06:09:17 PM PST US Subject: Zenith601-List: Re: I don't understand... From: "Sabrina" If your XL winged craft is parked outside, the upgrade could actually degrade the strength of the main spar over time since Zenith has moved back toward main spar AN bolts that cannot be inspected and re-torqued. I don't know if it would take months or more than a year, but at some point while I am in college I would be in worse shape than I am now.

Sabrina In the Q&A he has always said rivets are better than bolts. The bolts in your pic might just have been temporary since the hole is the same size for either. Mine is riveted all the way across... it makes no since to add bolts where there is no inspection covers and I don't want to have to re open the wing in two years. Not to mention the added weight of bolts.

Also the aileron balance is bolted in between the two new aileron ribs. I don't like either of these solutions.

As I understand it this coin has two bad sides . . . We discussed this situation at my last EAA chapter meeting. One member (who happens to be a supervisor at Boeing) mentioned a potential problem with aircraft rivets. His point was that if the rivets are not properly set they may not compress the parts they are supposed to hold together. This is not an issue (according to him) with bolts since the torque applied is directly reflected in the joint. I didn't really understand his comments, but the bottom line is there are potential problems with bolts or rivets - especially rivets set by builders who may have selected the Zodiac design because it didn't require setting any hard rivets.

I certainly understand "no solid rivets" comment. I have every intention to rivet mine, but I'll be buying a bunch of cheap aluminum at Home Depot and a bunch of extra rivets to practice with. Fortunately my airport is "infested" with RV builders, so I have some more experienced people around. I just can't see having the inspection headache and weight.

Machin" Subject: Re: Zenith601-List: Re: I don't understand... I guess I don't understand. If a bolt is properly torqued and has some locking feature it is just as reliable as a rivet. Our aircraft has hundreds of non serviceable bolts, never been a problem. Certified aircraft as well.
