Given the state of this kit, I think you should be fine. That is assuming it is the same kit as the one I was considering to replace my Zodiac. --> Zenith-List message posted by: Bill Cardell I introduced myself to this list probably six months ago and promptly disapeared.

That does give you toe in or out but unfortunatly it does not tell you if it is centered relative to center line of airplane. Another method is to drop plumb lines from the center of airplane front and rear. Hold a 4' straight edge next to the tire and have a friend drop a plumb line from each end. Do this both sides and compare each end to the centerline. You will have to convert this 1/16" to degrees hovever. Can't advise on trigear planes, used 0 toe in-out on three taildraggers (RV3, Glasair and Legal Eagle) and they all track perfectly. You can however get many opinions on this subject, I guess that is why it's called "Experimental" LOW&SLOW John ________________________________ Message 4 _____________________________________ Time: 05:39:15 AM PST US From: "Cy Galley" Subject: Re: Zenith-List: Newbie stuff --> Zenith-List message posted by: "Cy Galley" Sorry, but NOTHING in the Regs say anything about 51% when it comes to the repairman's certificate.

If anyone is interested, I'm hoping to splice two peices together for the 12' rear wing channel so I don't have to bend a 12' channel as one piece.

I put the wheel forks together and drilled the holes for the axle. The centers are right on. The hub spins free and does not wobble relative to the wheel forks, but when I added the tires that came with the kit, 4.80X8, it rubs in spots on the wheel fork. The rubber weaves back and forth. I have one side that is perfect, but the other two tires rub the wheel fork. The tire pressure is set to 90 lbs as per what is listed on the side wall of the tire. I have tried both remaining tires and have even used a different fork. Any ideas. One other question where the devil do you find replacement tires? I have been looking for a spare set of tubes and tires. Pinched one of the tubes in the split rim. --- Robert Rehmel --- traveler601@earthlink.net ________________________________ Message 7 _____________________________________ Time: 09:11:25 AM PST US From: Elwood140@aol.com Subject: Re: Zenith-List: ZAC email for approval of Plans Modification (601XL) --> Zenith-List message posted by: Elwood140@aol.com In a message dated 9/1/2003 9:58:47 AM Central Daylight Time, cookwithgas@hotmail.com writes: > Does anyone have Nick's email address (support@zenithair.com?) so I can > send > him a sketch of a modification for approval? > Try: nheintz@zenithair.com (that's what's on his business card) Or: info@zenithair.com they both work for me.

You are going to have tires that feel like concrete! Is that 90 psi the maximum rating on the tire? You certainly don't need that much pressure.

Chris H says inflate till the weight of the aircraft depresses the tire by one third, rim to ground. That's about 25 lbs in my book.

Your tires are way over-inflated, and have probably expanded some. Go back to about 25 PSI, and the problem will most likely go away. Also, remember that almost no tire is perfectly round, or symmetrical in either tread or sidewall Paul Rodriguez 601XL Corvair ----- Original Message ----- From: Leo J.

To have the >fuselage ready for the show, the cabin area of the fuselage was not >primed. [Does Zenith prime the parts that require ZnCr?] >No, in the kit we do not prime the parts. We only apply the zinc >chromate on pre- assembled parts, such as the main wing spar and >cabin >sides.

[Will the 6061 survive without the extra protection?] >It is all a question of time. Zinc chromate has an outstanding >history >to prevent corrosion. The same cannot be said for parts that are >not >treated. -------- So there you have it. I'd love to see a study or something, but for now we're going with Nick and priming (mating surfaces, at least). Meanwhile.... We think trunk paint is really cool. We theorize it would be a simple and utilitarian way to do the interior of an 801. I noticed a lot of composite aircraft at OSH used it for just that purpose, but didn't see many (any?) aluminum aircraft that used it. Has anybody experimented with it on 6061? Maybe it doesn't adhere as well to AL?

I'm interested to know how long you took to build your 701, (or a conservative estimate of how long it will take you.) I've heard people talk about build times over 1000 hours, but the company still advertises and claims an average of 400-450 hours. I'm just looking to get an average idea of what my father and I can expect as first time builders. Also... got that ride in a 701 last week.... thanks much to Tom Lazear of Ohio.... Tom's 701 is beautiful with a cool center console he designed... runs from under the panel to the floor for additional instrument space... very neat install.... It also flew wonderfully with the 912! Still looking for info on Midwest eng's rotarys... email to the company go no response.... Thanks in advance for any info!

Might build the third one in 350 hours. It gets easier AFTER you've done it.

As a first time builder and alone, I measured, and remeasured but still made errors. I had to do most of the fire wall forward installation and cowl design from scratch. Including painting fuselage and tail, I have about 2800 hours in it. some photos at http://members.thegateway.net/cfd Chuck D.

I'm figuring that mine will be flying sometime in the very near future. I think I am going to have an airplane that will do exactly what I wanted it to do when I purchased the kit 4 years ago. 1000+ hrs and not quite there.
