Your lucky you weren't caught in a 55 zone. Many of the interstate roads that go through Atlanta have a speed limit of 55. These are 4-5 lane interstate expressways, but the speedlimit is still 55mph. In some recent report, Atlanta was named the US's fastest driving city, but thats because our speedlimits are lower than other major metro areas. Everyone drives 75mph+ anyways.. When I drive down to Skydive Atlanta, the speedlimit doesn't go back up to 70mph until you get about 20-30 miles south of downtown Atlanta.

There was a thread about which container features were necessary for a CRW specific rig. http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=334271 I think much of that thread focuses on the safety and design aspects of a rig. I think a new Javelin will probably have all of the necessary safety features. The larger riser covers mentioned above are an excellent idea. I don't know if you noticed, but Jeff has those on his Javelin, and it makes the rig a lot cleaner looking (and safer). I wonder if Sunpath can make you larger leg straps (maybe with more padding).. with as much time as we spend under canopy (and the brutal openings we live through), I think wider leg straps will be more comfortable. I also wonder if anyone here has any experience with the cut-in laterals on the new Javelin Odysseys (on a CRW rig)... It seems that they were designed so that the rig will hug your body in a lof of freefly positions, but I wonder how useful/comfortable they are under canopy.

This has been discussed numerous times. See following thread: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=739564;#739564 Once I am done with my 16 sq. ft. canopy, that will probably be the smallest. :) http://www.geocities.com/darkvaporx/l16.htm

Just keep in mind that all pilot chutes are not created equal. With smaller pilot chutes, the margin for manufacturing and design errors goes down. Refer to the following thread for more details, and figuring out if your pilot chute is designed well: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?do=post_view_flat;post=132976;page=1;sb=post_latest_reply;so=ASC;mh=35 To answer your question more directly, I've had a Cobalt 170 in a Wings W-13 (proper size for a 170), using a Jim Cazer 24" pilot chute, and I found that terminal deployments were excellent and no hesitation. But subterminal openings were a bit scarier, often with some scary delays between throwing the PC and getting a canopy over my head.

Hope this doesn't start another gun debate thread.. but that's the the whole point of having an armed society. If some low-life decides to rob or attack another person, they better think twice, because that could be their last thing they do in their life.

Somewhat related, and mentions something about freefallers .. From the CRW mailing list:

What hardware do you have? What outputs does your LP player have? You can do something like: LP -> CD recorder (something like Philips CD recorder) Or LP -> computer sound card or a converter Then you can use any multitude of computer software to burn the audio tracks.

Are the line trim differentials only dependent on trim, or are they a function of line length as well? I have acquired another Lightning without factory documentation. The person I bought the canopy from did not know the trim. If there is a set value for the line trim differentials for rotation and 1 for sequential, can someone please post the differentials for the rotation trim? The A lines are 8.5', which seems awfully short for a sequential configuration on a 160. I put 1 test jump on the canopy. My only other reference was another canopy of unknown trim. Basically I want to know what the values are so I can sit down and measure the lineset and figure out this canopy's configuration before I start deciding what I will do with it.

Right... the website hasn't been updated with the pics from Saturday yet. I'm eagerly waiting for the pictures of the 70 way as well, hopefully sometime this week they will update the website.

According to the press, a 70 way diamond was built during the CReW record attempts this past Saturday. Hopefully we will get some first hand accounts once all these crw dogs return home, but until then, here is the news article. Congrats to all involved! Hopefully pictures will be available soon on the official website, but until then, here are the updates and pictures from the previous attempts. http://www.cfworldrecord.com/Updates.htm http://www.polkonline.com/stories/120103/loc_skydivers.shtml

Press and hold the power button for 5-10 seconds, that should do the trick in many cases. In most newer computer designs, the power button is a lot more of a suggestion than an actual switch.

Try using google's advanced search feature. http://www.google.com/advanced_search?hl=en Enter the website in the domain field. This will obviously only work if the site is indexed/cached in google's database.

Only had 2 out landings. Both were CRW related.. The 2nd out landing happened last weekend. A friend and I went to another dropzone because our regular dropzone was rained out. It was only a Cessna 182 dropzone, so we climbed to 10.5, and the pilot informed us the uppers were doing around 60mph. After consulting with the other person for a few seconds, we decided a spot about 8 miles from the dropzone would be good. We ended up landing 2.91 miles from the dropzone (I had a GPS with me). Our biggest mistake was probably not turning with the wind early enough. We flew into the wind for the first few thousand feet. So we wasted much of the potential of that 60mph uppers. By the time we turned back (maybe 7-8k) the winds at altitude weren't as high as we needed to get back. We were making good penetration, but we decided to put down in the best field we could find. Since I had the GPS coordinates, I decided to have a little fun with some satellite images of the area, and created the following webpage: http://www.geocities.com/darkvaporx/adventures.html It took us about 45min to an hour to hike back to a major road. I had a cell phone, and we called the dropzone to tell them we were alive and well. But since we weren't near any roads, we told them we would call them back when we could tell them where to find us. When we got to the highway, it wasn't long before a nice soccer mom and her kids picked us up and dropped us off at the airport. I really enjoyed that jump though, hell of a lot of fun.

I would look into using polycarbonate instead of acrylic sheets (that's what Plexiglass (the brand name) is). Lexan is GE's brand name for polycarbonate. Use Lexan or another polycarbonate sheet product. Acrylic turns yellow with age and UV exposure, and becomes brittle. It also can shatter either with age, or with excess pressure. Polycarbonate is shatterproof (essentially), and is EASILY machinable. I have drilled plenty of holes in polycarb sheet without any pre-drilling. Just use a relatively new sharp bit. Polycarbonate will also not dull or turn color with age. I usually get polycarb products from a local GE Polymers distributor, but you can probably find it in other places.

CAR AUDIO People, what to look for when looking at speakers
darkvapor replied to Viking's topic in The Bonfire
I don't think frequency response is so important in a car audio system. Most audio you will be playing in the car will not utilize a wide frequency band. If you plan on using an MP3 player, then that generally has a narrow frequency band as well. A key point to MP3 compression is removing frequencies that aren't very important to the overall quality of the sound. Fidelity is important, but not to the point of looking at frequency response curves. Radio frequencies and most digital signals really don't utilize the full range of human hearing (technically about 20hz to 20kHz). The reason I say fidelity doesn't matter in a car is because you have so many other factors. Road noise, speaker location, physical and acoustical interactions with the car, and just a whole bunch of other factors that make getting the highest fidelity speaker rather unimportant. I think it also depends on whether you drive a 1995 Honda Civic or a 2004 BMW 745.. get the best value, not the best fidelity. When I upgraded the system in my Jeep GC, I had a friend at best buy hook me up with a discount. Never pay retail. The markup is horrific. For speakers, I liked the Pioneer TS-A1680R's that I got. I got a slightly different model (180watt version) in the front speakers. However, one is a 3-way, the other a 2-way speaker. It has secondary and even tertiary voice coils built into the speakers. This gives you a much better reproduction, since, effectively, you have tweeters as well. I think the other biggest factor in improving the sound quality is the use of an amplifier. Adding an amplifier really complicates an installation, but the clarity and power is just unbelievable. I used to use the head unit to power the speakers, and after about 1/3 power, you could hear distortion. After about 1/2 power, the distortion would become overwhelming. With the amplifier that I am using now, at about 1/6th power, it is as loud as I can stand, and the clarity is excellent.
