Make My Camera an "Extra Small" Please!

    There's only so much real estate on or around your head for camera gear. The average Joe/Jane tandem camera person will fly a helmet with a 35 mm SLR and a miniDV video camera. Each camera can be mounted any number of ways, but the sum total of their weights is still enough to make your neck tired. The more advanced camera flyers involved in record jumps, night jumps, etc. are attaching more equipment in addition to the usual video and still cameras, such as lights and battery packs. Suddenly, the weight of the helmet goes from 5 or 6 pounds to 15 or 20 pounds. Aside from all the weight issues, there are the dozens of stories of snag incidents. The more junk you bolt to your melon, the more your chances increase for a line snag.
    It's pretty cool to see an expert camera flyer with a finely configured helmet, but it's still scary to see the number of potential snag hazards and the amount weight balanced on that camera flyer's neck. Enter the "lipstick" or "bullet" camera. The bullet camera is simply the imaging sensor of a standard video camera mounted inside a groovy little metal tube. It has a lens at one end and a cable at the other. Most of the models available are only 50 to 70 mm in length and roughly the diameter of a nickel. Nowadays, the picture quality is basically equivalent to any miniDV consumer camcorder on the market. Some models include the ability to change lenses, filters, and mounting hardware.
    First, a word on resolution and media (as in, recording media: tapes, DVD's, memory cards, etc.). We won't go into the bits and bytes or the exact specifics, just the general terms and numbers. (If you're a video expert, forgive the simplicity or lack of depth.) The standard format for video storage on today's small camcorders is "miniDV." The newer video recording technologies in camcorders are DVD disks and "microMV" tapes. DVD is great quality, but the jury is still out on whether a DVD camcorder will hold up well in freefall. The microMV tapes are tiny, to say the least, but microMV uses video compression to allow it to store an hour of video on a dinky little tape. The compression in microMV compromises the quality of the picture. The quality of microMV lies somewhere between miniDV and VHS. The miniDV standard stores frames of video at a resolution of 720 pixels by 480 lines. It, too, uses compression to store video, but doesn't sacrifice as much quality as microMV. miniDV is still a great choice overall for skydiving video. It's small and it provides great video quality.
    Television in the US and some other countries is based on a standard called, "NTSC." NTSC defines a television screen's resolution to have 525 lines from top to bottom (the number of pixels across isn't really an issue here). The closer your camera gets to saving 525 lines of resolution, the more your video will look like a professional or "broadcast" quality picture on an NTSC television. For more details on the standards that define different video formats, do some searching on Google.com.
    In order to replace your miniDV camcorder, you're going to want a bullet camera that at least matches the resolution and picture quality of your miniDV camera. There are several different resolutions available in bullet cameras. As of the writing of this article, 380 lines and 480 lines are typical. 380-line cameras contain 20% fewer lines of resolution than 480-line cameras. If the picture quality isn't that important to you, you might be interested in a 380-line model. This would be equivalent to a VHS, microMV, or maybe even a Hi8 recording. The ideal camera for the best quality is a camera capable of 480 lines of resolution (matching miniDV). The size of the little image sensor chip in the bullet camera also makes a difference in the clarity of the picture. Many lower resolution cameras use a quarter-inch chip. The better quality 480-line cameras use Sony's new third-inch chip, which is also happens to be capable of very low light and infrared (or "night vision") imaging. The bigger the image sensor, the more accurately it can differentiate between pixels in the picture that's coming through the lens. This equates to better contrast and color in the video. This is precisely why you see bigger lenses and imaging sections on professional cameras. A bigger imaging CCD is just like having more megapixels in the digital still camera world.
    There are a couple of tiny cameras available specifically for skydiving Ranging in price from $360 to $900 and up, each with their own selection of accessories.
    The "monkeyKamera," by monkeyKam, is based on Sony's ExView CCD chip and has an imaging resolution of 480 lines. It's the same chip technology found in late model Sony single-chip CCD camcorders. The monkeyKamera starts at $359, according to the web site. The other camera is the "SportsCam" from Mike Swain. The SportsCam is a "board" type mini camera that has a resolution of 380 lines of full color ("board camera" means that the circuitry and lens of the camera head are all mounted on a little circuit board in a little black box). The advertised price for the SportsCam is $899 and up. These tiny cameras weigh no more than 6 or 7 ounces and takes up very little space on your helmet. They add no noticeable weight in freefall.
    The camera "head" (the bullet or the little black box with the lens) provides a video signal to an RCA-type connector, which is connected to your camcorder's A/V input jack. An extension cable runs up from the camcorder to your helmet. The connector at the collar or base of the helmet allows the cable to break away in case your helmet is lost in action.
    Your camcorder is usually carried in a belly pouch and run in "VTR" or "VCR" mode. Camera kits typically include the hardware required to rig the camera head to most any helmet. Also included are a battery pack (batteries not included), connectors and cables, and even a pouch for your camcorder (check the manufacturer's web site for what is included in the base camera kit). Any "fanny" pack can be used for your camcorder, but check with the camera manufacturer for any custom built pouches they may offer. For instance, the "monkeyPak" from monkeyKam is a belly pouch that holds your camcorder, batteries, and switches for controlling the camcorder and bullet camera. The monkeyPak is specifically designed to make using your camcorder in a belly mount configuration easier. It gives easy access to the CamEye button and monkeyKamera power button, as well as a clear vinyl window that makes it easy to watch your camcorder's screen without having to remove it from the monkeyPak.
    The bullet camera requires its own power. Power is usually supplied by a battery pack. Most bullet camera battery packs use 8 AA batteries to provide 12 volts of power to the camera head. In tests, Duracell NiMH rechargeable batteries purchased at a local retail store were used to power the monkeyKamera and were found to last over 10 hours of continuous use! In an average skydive, the camera will probably only be turned on for a few minutes, so a fully charged pack of batteries should last for weeks and weeks, if not months.
    When flying a bullet camera, there's nothing new to learn, except for your procedures in the airplane. The CamEye is a great tool for controlling the camcorder without having to remove the camcorder from the belly pouch. An LED indicates the status of the camcorder (on, off, or recording). When you're waiting for the door to open, connect your helmet to the belly pouch cable, don the helmet, wake up your camcorder with the CamEye, turn on the bullet camera, wait for the door to open, then click the CamEye button to start recording and zip up your suit.
    If you wish, you can even rig the CamEye to the outside of your jumpsuit through a button hole (or grommet) OR you can even wear your belly pouch on the outside of your suit. In this author's humble opinion, it's wiser to wear the pouch on the inside of the suit. Less is more on the outside of your suit and around your rig's handles, when it comes to safety.
    Save your neck! Try a bullet camera and see how comfy freefall video can be. :)

    Aerodyne announces the market release of the Mamba canopy

    The Aerodyne Mamba is the ultimate high performance 9 cell elliptical designed with the more experienced pilot in mind that isn't looking for all the costs and pack volume issues associated with cross braced canopies. It is intended to compete with canopies like the Katana and Crossfire.
    Edward "Bushman" Anderson, President of Aerodyne Research, describes how the Mamba came into existence: "This product is the result of 2 years of continued Research & Development and test jumping, with the final version of prototype being test jumped in cooperation with the Norwegian 4-way team Arcteryx. The team has approximately 1500 jumps on the Katana and therefore had a good platform to relate to, whilst evaluating the Mamba."
    With a planform factor of 22.1 and an aspect ratio of 2.7:1 the Mamba is one of the most elliptical wings on the market today. As a comparison, the Pilot has a planform factor of 6.6 and the Vision 14.7. Despite its aggressive taper, the Mamba sports unparalleled openings and provides the jumper with a smooth controlled snivel & maximum forgiveness during inflation. It is extremely responsive to toggle input.
    One of the most impressive features of the Mamba is the glide ratio. Recent tests against other high performance canopies show that the Mamba has a definite advantage in this performance arena. With the Mamba a jumper will increase the ability to get back from long spots and have the absolute longest swoop landings ever experienced under a non cross braced wing.
    The Mamba has light toggle and riser pressure, allowing the jumper to explore all avenues of available control input and to maximize the performance of this new wing. By utilizing the light front riser pressure one can continue to increase both the speed with steep but controlled dives. The flare on the Mamba is powerful and easy to read, leaving you with total control of pitch angle. "From the moment you start your flare you will easily be able to gauge your distance and landing speed.
    Experienced canopy pilots will find that the Mamba is easy to land while maximizing their swoop distance and control.", so reports Ole Petter Hjelle, team captain of Arcteryx. "Our team member Tore Buer has already flown the Mamba during swoop competitions and put respectable scores on the board!"
    Design Features

    Fully Elliptical Planform - Provides phenomenal flight performance and landings.
    Pre Shaped Nose - Improved inflation and aerodynamics.
    Zero Porosity Fabric - Provides increased durability & longevity
    700 lb HMA Line - Provides exacting tolerance on line trims.
    Aspect Ratio - 2.7:1
    Planform Factor - 22.1
    Available Sizes
    90, 96, 104, 111, 117, 124, 132, 140 and 150 sq ft.
    The retail price of the Mamba is fixed at $ 1999 and we are taking orders now.

    Relative Workshop - 40,000th rig Essay Contest Winner

    Relative Workshop would like to thank everyone that entered the essay contest. We would like to congratulate the runner-ups for their entries; SSG Brian Heft, Maggie Downs, and Al King. A big congratulations goes out to Ben Liston for his winning essay and the recipient of the free Vector. Ben's essay is posted below.
    Why I Want to Jump a Vector
    I still own the first rig I ever bought: a Vector II. My friends and I refer to it as "Old Blue" and it has taken me through each license, to my first gold medal (Collegiate Nationals 1996), through countless video and coach jumps, and traveled with me around the world. When I was jumping in other countries, the language barrier was sometimes tough to get through, but gear checks were never a problem. I remember a moment in Italy when I sensed that the locals were a bit skeptical of me, but after I pulled out "Old Blue," the owner of the DZ nodded at my rig, went into the hanger, and emerged with his own Vector. In broken English, he turned me and said, "Okay, we jump." It turned out to be an incredible day of 8-way, pasta, and wine. This is just one of many times I’ve been glad to have a Vector. Whether I was jumping over the Great Barrier Reef in Australia, or filming my best friend’s first AFF jump, the rig has never let me down.
    As a rigger, I’ve always appreciated the craftsmanship, functionality, and clean lines of Vector rigs. I like that every feature of the rig is well designed and constructed with precision. For instance, the main pilot chute’s support tape is sewn at a 45-degree angle to mesh. Sure, it would be easier to sew it in line with the mesh, but the Relative Workshop sews it to minimize the stretch and increase the pilot chute’s efficiency. There is also simplicity and ingenuity in the reserve system. I don’t know why every manufacturer doesn’t use reserve pilot chutes that create drag regardless of the angle from which they are launched and springs strong enough to clear burbles and find clean air, but I’m glad The Relative Workshop does. Packing reserves into some containers is more like a wrestling match. With Vectors, the free-bag and pilot chute close into the container cleanly, exactly as they are going to leave it if they need to be used. Every time I pack up a Micron or M-Series for one of my customers, it’s hard to give it back. I want one of my own.
    Most importantly, Vector Microns are safe. I appreciate that Vector rigs are designed to be as snag free as possible, that the riser covers will stay closed in freefall, and that both the main and reserve containers stay closed until the handles are pulled. It’s also comforting to know that the cut-away system is made to the standards of the original inventor and that no creative liberties have been taken with this crucial aspect of the rig. From hard housing riser inserts to pin protection, the Vector Micron and M-Series are clearly the harness/container systems that all others are measured against. Yes, there are other manufactures out there, but in a sport that has a zero tolerance for error, I want the best. On top of all of this, I want to jump a rig made by a company that stands behind its products and provides great customer service. Every interaction I’ve had with The Relative Workshop has been outstanding. Whether during a visit to the factory or getting technical assistance over the phone, everyone at the company is professional, friendly, and knowledgeable.
    I’m at a point where I’m ready to take my skydiving to the next level and I know a Vector Micron can help get me there. The ergonomic harness will give me the mobility to perform my best in freefall and keep me comfortable under canopy, and the design innovations will keep me safe. I work in education and whether I’m training hard, or supplementing my "four-way fund" by doing video or coach jumps, I want a Vector on my back every time I get on the plane. Skydiving is changing, and while "Old Blue" needs a replacement, I won’t let it be anything but a Micron. The Relative Workshop makes the most dependable container in the world, so the question isn’t really "Why do I want to jump a Vector?" but rather "Why would I jump anything else?"

    Control Systems Malfunctions Information Sheet

    Performance Designs has released safety information regarding control systems and related issues that may result in malfunctions. The text below is the conclusion from that paper. For a more detailed discussion go to the education section on the PD web site and click on the article "Control Systems Malfunctions Information Sheet".
    Research Conclusion
    Setting a canopy’s deployment brakes correctly, which includes the proper stowing of the excess steering line, is an important part of the packing process. Failing to do this correctly may cause a control system malfunction or other type of equipment malfunction.
    Every time you deploy a canopy you must make sure it is fully controllable, with no unusual friction, binding, or drag on the control system. You must perform this check at a high enough altitude to allow the use of proper emergency procedures if necessary. Many jumpers do not perform control checks on every jump, and some even wait to release their brakes until they reach a fairly low altitude. If you do not perform a full controllability check after opening, or if you wait to reach lower altitudes before releasing your brakes, you may not discover a control problem in time to respond correctly.
    If you need to let go of your toggles in flight after releasing the brakes, you should place them on the risers against the guide rings before releasing them from your hands. Letting go of the toggles suddenly while they are pulled away from the guide rings may allow the toggles or steering lines to entangle with part of the riser assembly or some other object.
    A misrouted steering line, entangled steering line, or any other type of problem involving the control system may severely limit your ability to control the canopy and should be considered a serious, life-threatening malfunction. As with any malfunction, you must follow proper emergency procedures if you experience this situation. Jumpers have been severely injured and killed while attempting to land canopies with malfunctioning control systems. Even if you are using a canopy size or wing loading that is considered “conservative,” you may be severely injured or killed if
    you attempt to land a canopy that you cannot fully control.
    You should understand how to properly use every component of your parachute system, and understand any instructions, manuals, or other information supplied by the manufacturer. If you have any questions about a particular component of your parachute system, seek the advice of a qualified rigger or contact the manufacturer. If you have any questions concerning canopy deployment, canopy control, or emergency procedures, ask a qualified instructor for assistance.

    Mandatory Inspection of Skyhook equipped rigs

    Riggers (and owners), please be sure that the Sky hook hardware is sewn to the white free bag bridle correctly on all sky hook equipped rigs shipped between October 12 and December 1, 2003. There is a drawing of the correct installation and set-up sewn right next to the Sky hook on every rig, and the Sky hook itself is labeled.
    However, if the Sky hook hardware were sewn on the bridle backwards during manufacture or subsequent repair, (with the pointed end of the hook facing the pilot chute, instead of the bag) then you would tow your reserve pilot chute if deployed in response to a main total malfunction. As the instructions state, this pilot chute in tow can be fixed by pulling the yellow RSL tab.
    Remember, this situation can only be caused by an installation error at the factory, or during a rigger repair of a damaged bridle. It cannot be caused by a packing error. A PSB (PSB#20031203) has been issued in regards to this issue.

    Fluid Wings Announce Prime Hybrid Canopy

    Fluid Wings is a new and innovative company based in DeLand, Florida - which is aiming to close the gap between the parachuting, speed flying and paragliding. The company was born through a love of human flight, and focus on an engineering-based approach. Fluid Wings draws from the expertise of Scott Roberts, a skydiver with over 15 years experience, who has been competing for more than a decade; Kevin Hintze, an active pilot, paraglider, speedflying instructor and test pilot; as well as Shane Shaffer, chief test pilot and production lead.
    From the first of June this year, Fluid Wings will begin production on their newest main - The Prime. The Prime will be a 9-cell hybrid main, available initially in sizes from 150-190 square foot in a combination of ZP and low porosity nylon. The canopy is aiming to provide pilots with a fun and predictable flight, with focus also being placed on how easy it is to pack. The Prime will look to cater to jumpers of all experience, being easy enough to handle for newer jumpers, while still being responsive enough to be fun for the more advanced skydivers. Stock colors are Royal Blue top skin and stabilizers, with a white bottom skin and ribs. Please note that bottom and rib colors are limited to white due to color section of low bulk fabric. The canopy ships with Vectran lines and soft-link connectors, with a low-bulk option packing up to a size smaller is also available.
    “The Prime is responsive and playful, while still easy to manage. It has a good glide for those long spots, with a nice strong flare for tip-toe landings,” said Scott Roberts of Fluid Wings. “We like her a lot and think jumpers will too!”
    The Prime will retail for $2090 with all options. You can contact Fluid Wings at [email protected] for more information, purchases or demo requests.

    Aerodyne introduces the Icon harness-container system

    Aerodyne is happy to announce that it secured FAA TSO C23d approval for its Icon harness-container system. Although we have already been displaying the Icon rig at various events in 2003 and have started to take orders some time ago, we are now able to launch the official introduction.
    It looks good

    Design, comfort and fit are of paramount importance. The design team of Aerodyne have worked hard to find the perfect mix of these elements. We have received a lot of good response to the Icon and we are confident it will help us to gain a place in the rig market.
    Safety first
    The Icon is a modern harness-container system that relies on many industry standards, but also includes new features such as the miniforce™ 3-ring system. This patented 3-ring system, designed by Aerodyne’s head of R&D; Michel Auvray, reduces the pull force required to cut-away the main canopy. With today’s smaller and elliptical main canopies, malfunctions often lead to rapid spins with higher loadings and many skydivers have been experiencing difficulties to cut away. The miniforce™ 3-ring system, coupled with “anti-twist” metal housings on the risers and a shaped sure-grip cut-away handle, considerably reduces the likelihood of cut-away problems.

    Other safety features of the Icon include:

    “Link-Stop” panels inside the main container to prevent the risers from wrapping around or catching on the corner of the reserve container;
    A line stow retention system on the reserve freebag to help control reserve deployments at high speeds, while not sacrificing low speed requirements;
    A solid platform in the reserve container to maximize the launch of the pilotchute with one of the strongest spring coils in the industry (23 kg).
    A base price that includes pretty much everything
    In its standard configuration the Icon offers all the popular items, such as a harness with articulation hip rings, all stainless steel hardware, choice of wide or narrow chest strap, a hand deployed pilotchute with “kill line” bridle and an aluminium hook knife. Each Icon rig is also equipped to receive a Cypres or similar type of AAD as well as a Stevens RSL system. Consequently it is very easy to retrofit an Icon rig with a RSL system, just by adding the actual lanyard. This greatly increases the second-hand value of the rig. Relatively few options are charged for additionally: They only concern the choice of a Hackey Sack or Freefly handle on the hand deployed pilotchute, a Stevens RSL lanyard or custom embroideries.
    A range of sizes and colors to customize your rig

    For the Icon Sport, not less than 5 different container sizes are available, while the harness is always made to measure. Customers can choose from a range of colors in Parapack and Cordura fabrics.
    Icon Student
    For instruction purposes the Icon comes also in a Student version with adjustable main lift web. The standard configuration of the Icon Student includes a BOC hand deployed pilotchute. To configure the Icon Student further for a specific method of instruction the available options include a direct bag with staticline, a BOC or hip located ripcord with spring pilotchute, as well as secondary AFF jumpmaster handles.
    Online ordering

    As is true for all Aerodyne products the Icon can be ordered either through one of our distributors or via our website www.aerodyne-int.com
    We offer an on line coloring program enabling customers to visualize their custom Icon before they confirm the order.
    Try an Icon
    Aerodyne representatives will demo the Icon harness-container system over the Christmas period. Meet us at one of the boogies in Ampuriabrava, Eloy, Capetown or Margate and we will be happy to show you the Icon. Naturally this will also be an occasion to test jump one of our main canopies.

    Aerodyne introduces its A2 tandem canopy

    Aerodyne recently started to ship demo’s of its A2 main tandem canopy. The A2 is an elliptical 9-cell canopy with a surface of 389 square feet. It is a so-called hybrid construction, meaning that the top skin is made out of zero-porosity fabric while the bottom skin is constructed from a 0-3 cfm F-111 type fabric.
    Initially Aerodyne baptized this canopy with the name "Gemini", but having been confronted with a claim that this name is already used for a parachute canopy by the Canadian company Canadian Aero Sports we decided to change the name to "A2".
    The A2 caters to tandem equipment owners who are looking to replace only the main canopy. With this goal in mind Aerodyne decided to ship each A2 with a set of miniforce™ tandem risers. "By supplying a set of risers with each A2 canopy we are preventing any compatibility problems with the various tandem rigs on the market", explains Edward Anderson, who is Chief of Operations at Aerodyne Research in Florida. "The tandem owner can easily install the A2 into any rig and is not confronted with the issue of steering line lengths or the position of the steering line guide ring on the riser. And of course there is the added benefit of the unique miniforce™ risers. The "elongated" middle ring of this 3-ring release system significantly reduces the pull force required to cut away. Especially in the tandem environment we feel this feature greatly enhances safety."
    The airfoil and the conservative planform factor of the A2 guarantee superb handling characteristics minimizing the workload of tandem masters. Not only will they find the toggle pressure, turn response and flare power they have been seeking, but they will be pleasantly surprised by the soft on-heading openings. The turn recovery and ability to slow the canopy in no wind conditions are additional features that will be greatly appreciated by all tandem masters. The A2 is equipped with Spectra suspension lines which make for considerably less bulk and a more compact container on the back. Because of their lower weight the Spectra lines also reduce the risk of line dump and subsequent premature opening of the deployment bag, a significant cause of malfunctions.
    We have designed this canopy to maximize safety, but at the same time we made it an economical tool that will maximize the number of jumps per day. To reduce packing time we chose a hybrid construction. To reduce air time we built a wing that will fly slowly in brakes, but gives you a significantly higher rate of descent when flown at full glide.
    The A2 comes standard with miniforce™ risers, Spectra 1500 lines, a slider with lightweight stainless steel grommets and #6 stainless steel rapid links.
