Please pardon this intrusion. This note is not specific to your particular list, but regardless of what you are building, restoring, or flying, an issue exists that could potentially affect all of you who fly in the United States. That issue is the Washington DC ADIZ. This ADIZ was put into effect as a temporary protective measure for Washington DC airspace after 9/11. There is now an NPRM out to make this airspace *permanent*. The original comment period for this NPRM expired yesterday, November 2. However, the FAA has now extended the comment period for another 90 days, so if you did not get your comments in, HERE IS YOUR CHANCE! Information on the ADIZ, and why we are fighting it, can be found here: http://www.aopa.org/adizalert/ I live underneath the current DC ADIZ, so I get to play with this every time I fly. The AOPA page above gives a good summary of what has happened in this area since it's inception. Help on formulating comments for this NPRM can be found here: http://www.aopa.org/adizalert/help.html Comments on this NPRM can be submitted (online) to the DOT here: http://dms.dot.gov/submit/ Instructions on how to navigate and fill out the DOT page to submit your comments are available here: http://www.aopa.org/adizalert/faa_help.html There are over 18000 comments against this NPRM at this time. If yours is not one of them, please take the time now to submit your comments; every one helps. If this ADIZ becomes permanent, then there could be an ADIZ coming to an airspace near you in the future! I thank Matt for allowing me to send this to you. Even if you don't live near the DC area, please do what you can to protect your flying priviledges... submit your comments!

Flew up to Purdue to visit my son. It's just inside my 35 NM flight radius. I have this cool new folding bike my wife is getting me for Christmas and since the weather was so nice, I talked her into letting me use it (please, just this once!) to go riding with my son. It was a little risky ordering it because it has full size 26" wheels. I calculated it would fit in the plane, but you know how it is with complicated shapes - never know for sure until you try. The good news was that although a snug fit, I was able to fit it nicely into the baggage compartment after removing the seat, handle bars, and front wheel. A couple bungie cords and I was ready to go! When I arrived, a 5 minute setup and Nick and I were ready for some serious bike riding around campus. Thought some of you might have toyed with the same idea so here is some info: Purchased Bike off of E-bay for $150 plus $30 shipping. 33.5 lb weight with full suspension & 18 speeds. Frame is made of 6061T6 aluminum (sound familiar?). Found out after it arrived that it is a Chinese import (like so many things these days). Rides very nice with the full size wheels.

I would be interested to hear more.

After scribing the lines I used a razor point permanent marker to darken the lines, the yardstick is flexible so it is very easy to use across the contour of the wing. It was very cheap and in my opinion works better than the fan. I also used an excel spreadsheet to document the work being done along with digital pictures.

Taking that a step farther, I advise keeping them close to maximum inflation pressure and let landing technique soften up the brick feeling. As winter sets in and average temperatures drop, physics (Charles' Law, Boyle's Law?) requires you to add air to maintain that pressure. If you are keeping too much pressure in your tires, you will see more wear in the middle. If they are too soft, they will wear more at the edges. The maximum recommended pressure for a stated maximum weight (per tire) is written on the tire. Even if you are a lot lighter than the maximum load allowed, I would stay around 90% of maximum recommended pressure.

I have 10 lbs. in the main tires and 5 lbs. in the nose wheel, really smoothes out the runway. In other words, tires and tire pressure must consider where you will be flying to and from. Chuck D.

I've always thought planes & bikes were a great combo. It's good to get those legs moving after a couple hours in the cockpit. And with a bike you can explore the area beyond your destination airport. Sometimes that $100 hamburger isn't within walking distance. My interest is finding a kitplane that can carry two folding bikes. I've seen some 20" bikes that handled well and weigh less than 25 lbs. The folded dimensions are 11" x 22" x 33". Unfortunately two are probably not going to fit in a 601 or 701. Definitely no problem in the 801. One last note about bicycling - wear a helmet! As with flying, it can be lethal to the unprepared.

In our area of the midwest (Fort Wayne, IN) the most likely need to deploy an emergency chute would be a bird strike. We have a resident population of about 1500 canada geese that circle the city each day. Some local accidents have been due to bird strikes, and they can make an aircraft totally unflyable. I want an alternate way to save my butt if needed! At Oshkosh, Chip Irwin said that they mount the BRS chute in front of the panel, deploying through a panel on the right side of the fuselage. This location is good for weight & balance and saves baggage area. His company sells the BRS chutes, cables and installation instructions for the Zodiac 601 series. From what I have seen in three years of evaluation, this is a superior installation location. Best Regards, Larry Zepp 601XL builder, just starting, J3300 with BRS chute Pres.

BTW, extra credit points go to Bill for the link to the dimension page. I saw this page a couple weeks ago, but I was looking at all sorts of planes at the time. Recently, I tried to find it on the Zenith page, but couldn't. Eventually, I became convinced that it must have been for some other plane. Nice to find out I didn't imagine the page :-) I've also located an 85% complete XL in Pensacola.
