Electronic gates also render ineffective the technique of sticking your legs out as you pass through the exit gate. But I don't see that as a problem. Just a slight change in the rules.

Kallend, you accuse hukturn of using weak and ineffective debating techniques yet you are the one who is attacking the person and not the idea. Do you think that by calling him selfish and unsafe you will bully him into silence?

Regarding the RDS from Skyworks Rigging: There are two ways to attach the floating stainless steel rings to the slider. 1) put the loop through the ring first then through the slider grommet 2) put the loop through the slider grommet first then through the ring After searching the forums I see other people are hooking them up using method 1. See Grant's photos in this thread: http://dropzone.com/cgi-bin/forum/gforum.cgi?post=1652714 However, I mistakenly used method 2 for my first 6 jumps with the system. When I switched to method 1 I noticed much faster openings. Is there more potential for a malfunction using either method?

Based on all the glowing reviews on dz.com I ordered an RDS from Mel over two months ago on March 14. On three separate occasions he has failed on promises to deliver it. Twice he said it would be done "by the end of the week" and the last time I spoke to him he said it would be done "by the end of the day". That was two weeks ago. The latest message on his answering machine says he was "back in the shop" last Thursday but I called that afternoon and got no answer. I left him several messages on his cell phone (because the answering machine at his shop is full) and he has not returned any of my calls. Does anybody know of a way to contact him?

Thanks to the staff at Chicagoland Skydiving Center for helping coordinate this event and accommodating the CPC. We had a great turnout this time and we look forward to the next meet at Sky Knights on June 9.

The weather forecast shows the winds steadily increasing all day but they will stay below 10mph before noon. So let's try to get started at 8am or whenever the first load goes up. John, can you make it there by then?

See my post (the 3rd one down) at the following URL. It describes a very simple method for setting up a speed carve course. http://www.dropzone.com/cgi-bin/forum/gforum.cgi?do=post_view_flat;post=2355417;page=3

I saw some pretty fast times for the pros in speed carve (2.63 seconds). Were they using the handicap (220 foot carve versus 185 foot carve)?

My post was not directed at you, dharma1976. Yours was just the bottom post in the thread. The "pussy" reference was for the benefit of the genius who made the following comment:

Try reading the following article: http://en.wikipedia.org/wiki/Depth_perception There you will learn that there are many cues that humans use to perceive depth. Most, however, are relative and can't give you absolute information (ie. they can tell you that one object is closer than another but they cannot tell you how far away an object is). Many cues can be rendered useless due to environmental conditions. Some cues, such as stereopsis, are useful only at short distances. Probably the primary cue that swoopers use is familiar size. A familiar object, such as a tree, subtends a smaller arc on the retina the farther away it is. But this cue requires familiarity with the objects in the environment. Jump in a new location and this cue can be severely hampered. That is why we use instruments to supplement our depth perception. And, no, the fact that you are still alive and you never used one does not mean that you are Superman or that digital altimeters are for pussies.

Quoting from Jim Slaton at canopypiloting.com: "5-8 cross/downwind"

I'll be there. So far the weather forecast is looking good for the weekend. Any updates on the swoop meet that Tom Joles was planning?

You're not going to get a good answer because it's not black and white. Some tail input will often be required to plane out depending on type of canopy, wing loading, and type of turn. Too much tail input will slow you down and hurt performance. It will also use up your margin for error. Digging, when I use the term, refers to excessive tail input close to the ground - a large last minute correction.

If women want to have their own special olympics that's their prerogative but I think it is degrading to treat their gender as a handicap.

I've noticed the hostility towards the JVX on dropzone.com as well. You can't even choose it as your main canopy in your user profile (it's not an option). I asked the mods to add it a month ago and it still hasn't happened.

Did you mean October 21-22nd?

There were three speed runs and four distance runs for which I didn't have footage. I used a four second blank clip for each of these runs so you could at least see the names and scores.

As I mentioned in the original post this file contains H.264 video and AAC audio in an MP4 container. This can be played in any DirectShow media player (such as Windows Media Player) but you need to have the proper codecs installed. You can use the Haali Media Splitter and ffdshow (both of which are free). If you have a slow computer and the video stutters you might want to try CoreAVC. It's not free (last I checked it was $9.95) but it's supposed to be the fastest H.264 decoder out there. Your other option is VLC. This is a media player that will play just about any file without needing any codecs installed at all.

I think there might have been problems on my end with the P2P sharing. Thanks to those who gave it a try. bob.dino has offered to host it. Here is the URL: http://www.sundered.org/2006cpc/ Right click on cpc2006.mp4 and select "Save Link As..."

I have finished putting together a video from the 2006 CPC Championships. The video contains every run of the competition (well, there were a couple that were missed) and shows the setup, approach, and landing. I also added subtitles that shows the competitor's name and his/her score for that run. The video was shot with a Sony HDR-HC3. That is a high definition camera that records in 1080i. Since the source resolution is so high I was able to drop every other field instead of deinterlacing it to produce progressive video at 29.97fps. The resolution was still pretty high so I downsized it by 20% for a final resolution of 768x432 (which is still higher than standard definition DV). Then I compressed it using H.264 (MPEG4-AVC) video at 750kbps and AAC audio at 120kbps. The result looks pretty good with little or no noticeable artifacts. The length of the video is 79 minutes and the filesize is 500MB. Skydivingmovies.com refuses to host the file so if someone else is willing to host it please contact me. In the meantime I will be sharing it using P2P file sharing on the ED2K network. Here is the link: ed2k://|file|cpc2006.mp4|521741892|F89EF78AE4A737EE4BB4A48DE1CB3A82|/ You'll have to cut and paste this into your ED2K client. Sorry, I couldn't make it clicky because it kept getting mangled when I tried that (it insisted on putting "http://" in front).

If you are in level flight when you drop the weight the canopy will start to climb. Assuming you let off on the rear risers to offset this effect then your angle of attack will decrease and so will your drag.

There were a lot of people doing 450s at the CPC Championships this year. But the best distance scores (John Zuliani, Tom Delibac) were from 270s. They got 561 feet and 563 feet in the first distance round.

Please refer to the following URL: http://en.wikipedia.org/wiki/Lift-induced_drag Here they give the formula for induced drag: k * L^2 Di = ------------------------------ 0.5 * rho0 * Ve^2 * S * pi * A Notice the term L^2 in the numerator. This means that induced drag is proportional to the square of the lift.
