" I have thought about this also. Two things come to mind right away. 1. The geometry of the nose wheel will have to be changed so it would freely castor. If you just leave it like it is, you wouldn't get very far without the wheel trying to turn sideways. 2. Tension on the cables. As it stands, the nose wheel steering limits the amount of force you can place on the rudder cables. I guess this is an issue with tail draggers. I considered putting a swivel where the nose gear goes and install the steering rods if I had decided to build a tail dragger. Now that I have my nose gear installed along with the rudder pedals, it turns fairly easy after applying a little grease to the bearings. If you decide to do away with the nosewheel steering I'd like to see some photos.

From: "Garrou, Douglas" --> Zenith-List message posted by: "Garrou, Douglas" This is only partly true. It is true that, for the most part, the racist-moron (redundant?) guy's speech is protected in the U.S. under the First Amendment, which means that the GOVERNMENT can't jail him for expressing his idiotic views -- until he starts to advocate the violent overthrow of the goverment, or something really extreme like that. One theory, which I subscribe to, is that it is important to let racist morons speak in public, because they are their own worst enemies. Just for example, it never ceases to amaze me that white supremacists are generally the dumbest white people on earth. Coldly ironic, if you think about it. However, it is a common error to assume that our Constitution's protection of free speech against governmental punishment means that we have to put up with people like the racist-moron guy no matter where they may be spouting off. The marketplace of ideas leaves us free to boycott certain manufacturers, if you will. If this guy was in your house, you could of course kick him out, and I hope you would. This list is Matronic's house. Unless they are part of the government, which I doubt, they can kick him out. They can do so for pretty much any reason, including the fact that the other guests in their house don't like the guy. I should say, in closing, that I find his comments unbelievable and deeply shocking. The really sad and astounding thing is that he seems to have no idea what an ass he is making of himself. It's the finest self-ass-making job I have seen in several weeks. Cheers Doug DO NOT ARCHIVE ---Original Message--- Time: 09:05:12 PM PST US Subject: Re: Zenith-List: Unfriendly responses.

Positive steering is one the best things about the Zenith on ground handling. On my biannual, I had to use a Cessna 150 last February and it was a lot of work staying on the taxiway after being used to the solid steering on the 601. I'm sure your 701 would be the same. The flying rudder does seem not to correct itself well, because the nose gear is involved forward of its pivot point, but it would seem to be a lesser problem than what you would introduce by cutting the nose gear loose. If you did, you'd probably have to redo the geometry of the nose wheel to become a caster.

One of the possible reasons for a metal part that is hanging such as our steps to fail is vibration. Then add the impact of our weight and bang, we have a failure. I hope my solution will prevent such a thing. What I did was take a piece of auto water pump hose, split it and attached it around the torsion pipe at mid fuselage. When you step down on the step that part goes up against the bottom of the fuselage. With the rubber there it absorbs the shock also it should dampen the vibrations. Small piece, couple inches long. Maybe this can help, Best regards, Bill of Georgia ________________________________ Message 16 ____________________________________ Time: 08:06:41 AM PST US From: JAPhillipsGA@aol.com Subject: Re: Zenith-List: Unfriendly responses. --> Zenith-List message posted by: JAPhillipsGA@aol.com You guys got WAYYY TOOOO much money to be building your own airplanes!!!

I would guess that the further behind the steering axis the nosewheel is, the less sensitive it is to this misalignment.

Jack the non-expert in Clovis CA > >Tebenkof@aol.com wrote:--> Zenith-List message posted by: Tebenkof@aol.com > > Jack, As the new pilot of a 601 hds taildragger I can give you my impression of the rudder pedal pressure with no steering linkage attached-- The rudder is sort-of self centering because the forward hinge of the rudder makes it line up with the direction of flight. To turn you put pressure on the appropriate pedal and it turns. There is very little pressure involved and if you aren't careful you can put a small bit of pressure on one pedal and fly with the bubble out of trim without knowing it. I let a very experienced pilot fly some of my early time off the plane and he noticed minor ruder oscillation when no pressure is applied to the rudder pedals. He has watching me climb out at a steep angle and saw the rudder flop back and forth at a slow rate. When he mentioned it I could remember that I didn't have positive pressure on the pedals since I wasn't turning. Perhaps a bungee or spring on each rudder arm would take it out, but it's not objectionable when you know about it. It also seems to be more of an issue in climbs than straight flight. Every system has it's pros and cons, but I have gotten used to this one and really like it. Re ground handling without a positive linkage to the nose wheel, that's exactly what the tailwheel driver deals with. Differential braking is very important and I am in the middle of making Matco's suggested changes to the brake geometry so I can get better leverage to the master cylinder Ron N601TD ________________________________ Message 20 ____________________________________ Time: 09:28:34 AM PST US Subject: RE: Zenith-List: Nose Wheel steering?

The batteries went open, 12 volts no load maybe 5 volts under load. I the airplane world my solution is a two bus system. I used two 17 ah ( I believe) batteries, one for each bus. The alternator charges the batteries through two low voltage drop diodes. During starting a solenoid connects both batteries together. The two gel cells I purchased from Batteries Plus are small enough that they fit on the firewall behind my Stratus Suburu. This means that I was able to use smaller (lighter) wiring from the batteries to the solenoid and to the engine. This also means that in normal running I can run the engine and strobes, both electrically noisy devices from one bus and my radios and intercom on the other, thus reducing noise.

No one (including me) gives the car the mantainance as timed as we do to our airplanes. Normally we wait until the Government's date to give the engine the tune up is close to do it, regardless of the miles (or km) driven. Oil changes are around the same thing, for the tires, same thing... The brakes... until they sound "metal to metal", etc... They are few really carefull with cars, no need to tell us, you know your car. (Lets not make anothe flame here :-) With the airplane we are (have to be) very consistent, So regarding this type of electric system (need a batery to run the engine) I will advise to design a fail proof mantainance schedule, for example: If the batery life expectancy is 3 years, change it at 2 years. If your motorcycle uses the same type of batery, use a new one in the plane and the one used from the plane in the motorcycle, this will give a "time cushion" that probably the one in the morotcycle will fail first. The alternator can be cleaned, bearing repacked or changed and carbons (contacts) replaced every 200 hours (?) I do this mantainance in my cars alternator about every 50,000 km, and never have a failure Same goes to the stater. Regulator normally fails when the alternator is "erratic", or batery is not holding the charge and the alternator over works... Hope thjis helps. Just one point of view.
