You have full power but are going relatively slow. It is kind of like checking the mags on a gravel strip. A lot of time I check them while taxiing at 1500 rpm or so. I must admit it is more of a quick functional check not a classic run up. In a Cessna or Piper you can check them during your take off roll. Not in the 801 you are in the air too fast. Hopefully you have done a full classic run up in the not too distant past. When I have a big crosswind on take off or landing, I use no flaps and approach or rotate at about 60 mph. At that speed you need to give it lots of down elevator once you get it on the ground. Thank goodness my home field rarely has cross winds and when there is a crosswind it is a williwaw with 30 gusting to 60+ . Not flying weather. Even the 121 operator takes a brake. You have to realize in Valdez there is a 6000' mountain 1/4 mile north of the runway. The terrain warning in my Garmin 296 GPS goes off on climb out and on base. Believe it or not it is distracting! I'm a product of the 70's, I do full stalls and I only do a no flap landing in a cross wind. All other landing and take offs are with flaps. Take off with 10 degrees and landing with 40 degrees. It was calm the two days I was practicing. I guess I should practice no flap take off and landing! My thought is the tires wear out a lot faster than the wings. My philosophy is get it off and on the ground at the lowest speed possible. As an engineer I know the momentum increases at the square of the speed. If you want to walk away from an accident it should happen at the slowest speed possible. >Bill, educate me please.

This is a level about 8 inches long. I did use a laser device to level my bench, but the primary purpose of the laser was to make the surface of the bench flat rather than level. I mounted a second piece of particle board on different sized shims depending on where the laser hit a stick at that point. I don't think there is any exact way to get a perfect level on either the bench or the airplane parts. The best you can do is the best you can do. Nearly anything will fly.

In the CNC and metalworking industry, .0005/per foot is considered "level". Now, This is just my opinion but, if you can keep it below .5 degrees measured over 12 feet( the length of the table), I should think this would be plenty close. BTW, considering your table is prolly wood and it is most likely sitting on a concrete floor that is about 4" thick, you could measure the levelness once a week and get slightly different readings fairly often. Also, using your laser, take measurments at several different points along the length of the table- you may be suprised/ dejected at the results! There are ways to create a table that would stay flat and level, but for this application I don't think it's worth the trouble.

You use the flat table to take any twist out of the main spar and level to get the rear spar to be in the correct position relative to the main spar. This is required because of the tapered wing. >The wings won't know level from diddle --------------------------------------------- Paul Mulwitz 32013 NE Dial Road Camas, WA 98607 --------------------------------------------- ________________________________ Message 9 _____________________________________ Time: 11:44:32 AM PST US From: "Jeff Small" Subject: Zenith-List: and we wonder why we lose airports --> Zenith-List message posted by: "Jeff Small" >> We have several people on my field that think high speed passes are >> dangerous.

What details? Here are some: The siren I found on Ebay. The seller said it came off a boat. It is mounted on the belly, just forward of the spar with machine screws and Rivnuts. I have a push/push button on the instriment panel to activate it - through a headlight relay from J C Whitney. The air horns came from J C Whitney (three horns). They are mounted on the fuse right side, just aft of the wing trailing edge. Push/push switch on the instrument panel to turn them on and off, again through a headlight relay. The compressor is mounted on the upright that goes to the shoulder harness mounting bracket, under the baggage compartment. The siren is great to sound off, just prior to engine start - clears the prop! The air horn is great when cross country and you pull up to the service are. A blast of the Calvary Charge gets line service personnel attention every time. One cross country experience: At a tower controlled airport I was parked just below the tower. I had blown the horns when stopped, just before engine shutdown. This got immediate service - not one but six people. After servicing, I blew the siren just before engine start. Called the tower and was cleared to taxi to runway 14. When ready, I requested a VFR departure to the south. The tower came back, "Experemental 601Z you are cleared for take-off on runway 14, maintain closed right hand traffic to runway 14, high speed pass down runway 14, with siren and horn, approved. Right turn out and VFR departure approved. Have a fun day! I am 71 and in my second childhood - my excuse.

While expensive ($90 for a 24" model) they are not completely out of reach: http://md-smart-tool.com/index.htm They self-calibrate: place the level on any flat surface and push a button. Then turn it 180 degrees and push another button. -- Craig -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of Leo Gates Subject: Re: Zenith-List: Level --> Zenith-List message posted by: Leo Gates I used a 4 ft carpenter bubble level to check level and flat on my 4 X 12 ft work table while building my 601HDS.
