Title: "Building and Flying the FLiK - Basic Research's latest BASE specific canopy" by Jim Jennings

Article:

Designing and Building a BASE canopy today requires a great amount of testing, imagination, and canopy knowledge. As part of their ongoing
research and development process, Basic Research goes to great lengths to seek out the most advanced BASE jumpers today, provide them with a range of test canopies and capture their feedback in order to develop superior products.

The input used to design and develop new technology is backed by jumpers who are currently pushing the envelopes in BASE, jumpers who's talent has been proven at BASE competitions, and pilots with thousands of skydives and BASE jumps who have experience with multitudes of different canopy types. Also highly regarded by Basic Research are the contributions and viewpoints from the average, everyday jumper. The end result of this extensive and continuous development, testing and feedback is the FLiK, Basic Research's newest BASE specific canopy.

Aside from the development of the Tail Gate several years ago to prevent slider down line overs, another major safety enhancing technology in BASE jumping canopies has been the introduction of bottom skin vents or Vent Technology, Vtec for short. Three years ago Basic Research introduced Vtec on the FOX canopy to improve slider down canopy inflation. Vtec has markedly improved inflation time during slider down or slider off BASE jumping, providing a steerable wing immediately to help avoid object strikes. Moreover, the past three years has provided plenty of occasions when this innovation has saved jumpers from serious injury or death by maintaining a rigid and steerable wing during an object strike. This occurs because air is rammed up through the bottom surface of the canopy, keeping it inflated while it is in a descending direction instead of flying in a more horizontal direction requiring forward speed to keep the canopy inflated, as with a conventional BASE canopy. Additionally, with faster inflation times Vtec has safely helped bring BASE jumping to a new level, more specifically a lower one, opening up a new range of objects previously thought too low to safely jump. Vent Technology has been proven to make BASE jumping a safer activity, regardless of the experience or skill level of the jumper. As with the Tail Gate, the success of Vent Technology has been so great that almost every other BASE canopy manufacturer has chosen to copy the Vtec without varying the size, location, or number of bottom skin vents; a tribute to the innovation and success of Basic Research.

After three years of Vtec in the field on the FOX canopy, Basic Research accumulated the feedback they needed to develop "vent covers" that restrict the outward flow of air during flight thus improving the glide angle and enhancing the flaring characteristics. As a participant of the test jumping, I flew fly several different designs of vent covers. The major concern in the design of the vent covers was the impact they may have on the opening characteristics, possibly slowing down inflation. Another concern is the efficiency with which it actually covers the vent to improve glide angle. After an extensive number of prototypes, the desired cover was found. The covers on the FLIK evolved into a design that does not change the opening as compared to a Vtec without covers, and they cover the vent completely when the canopy is in full flight when air would otherwise be escaping out of the vent. In my opinion, it is the ultimate vent cover design.

Often BASE jumping exits are far removed from optimal landing areas so a need to cover long distances is sometimes required, therefore the glide angle of a BASE canopy should be flattened. Improving the glide ratio or glide angle of the canopy has not only been achieved by adding covers to the vents, but also by slightly increasing the aspect ratio from 1.97 on the FOX to 2.04 on the FLiK. Basically this has made the canopy a more efficient wing in terms of glide ratio and flare. The aspect ratio is a sensitive variable to change because it can negatively change the on-heading opening performance. In addition for the need to land in often tight areas, this is one of the main reason why BASE canopies have seven cells instead of nine. The FLiK has an aspect ratio that improves the glide angle and flight characteristics, however testing has proven that the on heading performance has not been affected.

Another feature of the FLiK has been an increase in the size of the stabilizers as compared to the FOX canopy. Larger stabilizers improve the turning characteristics by reducing side sliding and making for a tighter turning radius. This is a desired feature in BASE jumping in order to avoid object strikes through quicker response to riser or toggle input, or when flying in restricted spaces (such as in a narrow canyon). Several stabilizer sizes and where the line attaches to it were tested to formulate the most efficient wing while increasing the performance level. The testing also established that the larger stabilizers did not affect heading performance.

The line length of a BASE specific canopy can also affect on heading performance and the risk and severity of line twists. Add a slider into the equation, and the potential for offheading openings and line twists is increased because the slider has more distance to travel and the time it takes for the slider to reach its final resting place is increased as well as the time to full inflation. These considerations were a factor in the invention of the FOX by minimizing the line length. Compared to the FOX canopy, the length of the FLiK's lines were further decreased to provide, in my opinion, a BASE canopy that has superior on heading openings and more consistent opening speeds compared to anything else on the market.

The other change of the lines on the FLiK has been the addition of a fifth upper control line. This line was added to pull down more of the tail during the flare. The line is located inboard of the existing upper control lines and makes a substantial difference in the flare characteristics and turn response. This added upper control line in addition to the larger stabilizers results in a "sportier canopy" from the words of the parachute's creator Anne Helliwell, co-owner of Basic Research. The fifth upper control line has made such a significant improvement on the FOX and FLIK in the testing phases that Basic Research is now offering the fifth upper control line as a retrofit option to all existing FOX canopies.

Another feature of the FLIK is reduced pack volume to help make handling during packing easier and to counter the addition of bulk from the added vent covers. The FOX canopy was built with extra reinforcement, beyond the forces that could be achieved in BASE jumping. The sport of BASE jumping is always being redefined and it has been determined that some of the reinforcements on the FOX were in excess. To reduce the size and pack volume of the FLIK, some of the overkill reinforcement has been reduced resulting in a tighter, smaller, easier to pack canopy.

Production of canopies has been streamlined at Basic Research by the installation of a computerized hot knife cutting machine. This machine, provided and installed by Jyro (Paul Martin) from New Zealand Aero Sports, cuts a canopy out piece by piece with a computer controlled mechanical arm mounted with a hot knife – Jyro uses the same machine to cut out the Icarus canopies he produces. The computer software allows any pattern specifications to be entered into the system, allowing for easy alterations during the development of the FLIK test canopies, expediting the process. After cutting out the canopy, the pieces are handed over to the Basic Research sewing staff with ninety-three years of combined canopy sewing experience. This streamlined production process allows for test canopies to be produced immediately after the idea has been conceived, and it provides for an unparalleled turnaround time for custom orders. Basic research is now the only all in-house BASE gear producer, lending to the best customer service in the business, because the production timeline can be easily predicted and the manufacturer has complete control of the entire production process from taking the order to shipping.

During testing I personally performed nearly one hundred jumps on the FLIK, covering the complete delay spectrum from low freefalls and static line jumps to an array of delays up to terminal velocity, while often landing in small undesirable locations. I can now say that the FLIK out performs any canopy I have jumped by a wide margin. It has a reliably consistent and crisp opening with instantaneous inflation providing an immediate, rigid, and steerable wing, maintaining unsurpassed on heading performance. The response to riser pressure in stowed or unstowed brakes or via the toggles, is very quick, reliable, and predictable. Responsiveness to toggle pressure during the flare is also reliable and consistent, and the FLIK has an explicitly positive flare that holds deep until touchdown. This canopy has been nothing but a pleasure to fly, and to improve upon this canopy design in the future will require pioneering imagination extensive and testing. However I am confident that Basic Research's R&D team will be there mulling through the process.

I thought that the vents helped with canopy "pressurization" not "inflation" time. From what I have seen the vented canopies open in the same amount of time as the non-vented ones, they are just ready for control inputs faster. A canopy that pressurizes faster can fly faster. Please clarify this point for me.

Whyt not list the other canopies you have jumped and the number of jumps you put on them in your report? As a very active BASE jumper and as one who is currently in the market for a new canopy, I think this information would help to "sell" your choice. Without this data your report doesn't hold as much water and it seems more like you are kissing BR's ass. Maybe it was part of the deal you worked out when they sent you the Flik to test jump?? I don't know.

In no way am I saying that the Flik is not a great canopy and BR is not a good company (hell I own 2 Fox's right now and love them) all I'm saying is direct comparisons will win more customers than just stating that it outperforms other canopies. (in your opinion)

So how about the openings at terminal? How exactly are they? I do quite a few terminal jumps (8-14 seconds) and am concerned with the openings compared to other, non-vented, canopies.

Thanks for the article, it has provided me with more info so I can make an informed decision on my next canopy purchase.B|

Please clarify this point for me.

With quicker pressurization of the cells, comes faster inflation time. When you have a slow to pressurize canopy, you have a canopy that is not fully inflated - it waffles and is concertinering - not flying efficiently. When the canopy is not fully inflated, you have a faster descent rate, therefore it is not fully inflated.


>Whyt not list the other canopies you have jumped and the number of jumps you put on them in your report?

Let's just say that after being the first jump instructor in Lysebotn for two seasons, I was able to jump all the BASE canopies on the market - multiple times each - enough to make a GENERAL statement about the overall main characteristics as compared to the FLiK.

>As a very active BASE jumper and as one who is currently in the market for a new canopy, I think this information would help to "sell" your choice. Without this data your report doesn't hold as much water and it seems more like you are kissing BR's ass.

This is just a test jumpers review - not entirely specific - and should be taken as that. This was supposed to be an article to speak of the research processes and the building processes at BR with regard to the FLiK. It was not meant to be a way of "kissing BR's ass." I truly believe they have a better design with regard to the FLiK and have the capability to better serve their customers with an all "in-house" production - providing complete control of every aspect of the production and beyond.

>In no way am I saying that the Flik is not a great canopy and BR is not a good company (hell I own 2 Fox's right now and love them) all I'm saying is direct comparisons will win more customers than just stating that it outperforms other canopies. (in your opinion)

You're absolutely right!

>So how about the openings at terminal? How exactly are they?

The openings at terminal are brisk - very brisk. Therefore control measures are necessary. Do you own vented FOX's? It's about the same. I roll the nose cells on either side of the center cell in three or more times, directly control the slider by using black rubberbands on both center C's - double wrapping both to the center of a small hole mesh slider, double wrapping the tail lines and D's with masking tape for a line over control, and then indirectly stowing the lines under the tail pocket - doulbe wrapped by a normal size rubber tan colored rubberband. That's just me though... I'm totally satisfied with this setup after a few hundred terminal BASE jumps.

Hi Jim, Well written article although it sounds like it belongs on the BR webpage rather than a discussion forum. However, I'm compelled to comment on the following statement:

...the success of Vent Technology has been so great that almost every other BASE canopy manufacturer has chosen to copy the Vtec without varying the size, location, or number of bottom skin vents; a tribute to the innovation and success of Basic Research.


This would insinuate that CR copied the Vtec as there are only two other altenatives when it comes to vented canopies. For the record, CR develped both a lower surface vent and a valve in 1996. It was publicly jumped on many occasions including two Bridge Days.
Prototypes of what we sell now had vent positions fore, aft, left and right of our current production design. Vent size and number were also varied. More relevant is the fact that the vents/valves on the Black Jack are different in both size and position (both are similar, but different by design) from anything we saw on previous canopies.

To clarify: BR certainly popularized the concept of lower surface vents. When we decided to answer the market's desire for such a feature we did not copy anyone. We built on our own knowledge and then completed the concept with a (patent pending) valve. A vent with out a valve is like a seatbelt without a buckle.

No offense intended. You are entitled to promote your product, but verify your claims first.

Adam,

Thanks for the compliments, although I feel the article was rather hastily written and should have had a tougher edit before I posted it. I've heard about CR's claim to a vent in the late 90's. Maybe I should have been a bit more specific by saying "BR was the first to offer vents in the marketplace." With the obvious improvments to canopy inflation, one has to wonder why CR did not offer the vents after testing them.

Again, maybe I should have been more specific by saying something like "the blackjack and troll came out with vents of slightly different design and location than the FOX vtec, but are essentially the same in regards to performance."

BR's products are not my products. BR does not pay me for testing, only instruction. I am "loaned" a canopy to test and report feedback and eventually I have to return the canopy. I wrote the article because I like the FLiK and see it's design as an improvement of the FOX canopy and a superior design in regards to BASE specific canopies. This is only my opinion after jumping the FLiK, FOX, Dagger, Ace, BlackJack, Mojo and Troll.

>To clarify: BR certainly popularized the concept of lower surface vents. When we decided to answer the market's desire for such a feature we did not copy anyone. We built on our own knowledge and then completed the concept with a (patent pending) valve.

BR popularized vents in BASE specific canopies, that I can agree with (since they were first introduced and used for accuracy in skydiving), and thankfully somebody did. Again, sorry, my mistake, I was not aware that the BlackJack bottom skin vents, so similarily sized and located to the Vtec FOX, were not copied. As I said, I did hear well after the Vtec was introduced into the marketplace that CR, at one time (I am relatively young in the sport of BASE - only 5 years), developed and tested some bottom skin venting, but "scrapped" the idea due to undesireable performance. But, for all I know that could have only been rumor. Did CR discard the original idea because the venting was improperly placed? Just speculation - I don't know. When BR was testing the first Vtec canopies, we tried several locations and sizes before the final design was decided upon.

>We built on our own knowledge and then completed the concept with a (patent pending) valve.

Help me understand why a BASE specific manufacturer would ever want to patent a life saving/injury preventing innovation.

!!!TO ALL BASE JUMPERS AND THOSE INTENDING TO BASE JUMP!!!

Any life saving or injury preventing device or design should be shared and people should not care who came up with what or when - INMO (In My Humble Opinion). We should thank those who came up with/introduced into the marketplace new ideas that minimize BASE related injuries/fatalities, and we should continue to try and understand how canopies work and how they might be improved - I know BR is always open to suggestions and theories (but be ready to fully explain your theory with evidence) - and all other manufacturers should be too...IMHO.

>A vent with out a valve is like a seatbelt without a buckle.

That is your opinion and you are entitled to it. I flew the Vtec without vents for nearly 400 jumps and did not experience any problems fitting to the analogy "a vent without a valve is like a seatbelt without a buckle." I did however notice an improvement in performance in glide ratio with the Vtec covers.

On the subject of vent locations, I believe that the initial BR (two way) vents were well placed to minimize disruption to the canopy's flight characteristics, while still allowing excellent inflation.

However, given a one way valve inlet, I believe the (further forward) CR location is probably superior (since it places the valve directly between the first two suspension lines to load, and hence at the likely point of maximum air pressure.

Jim, can you tell us if BR ever re-evaluated the location of the vents, subsequent to the introduction of the covers (and hence the change in air flow characteristics of the vents)? And if so, what conclusions were reached (and specifically why BR decided to maintain the same placement that was ideal for a different kind of vent)?

Jim, Although this thread is beginning to diverge into different subjects and other message boards. I'd like to keep on the theme of my original post which had to do with the subject of copying.

On the BASE Board, Dwain points out that everything is a copy of everything, and it's quite true that creativity does not grow in a vacuum. However, our industry is rife with outright duplication followed by inflated claims of creation. Marketing claims are like a resume: By all rights they should be colored in your favor, but when they cross the line into fiction they lose all credibility.

Our vents/valves, like our vented pilot chutes, were not pulled from thin air but the idea was inspired, examined, prototyped tested and refined rather than simply adding a "clone" to our product line. I'm pretty sure I was the first to vent and valve a BASE canopy. Was I the first to explore or test the idea of vents or valves?- certainly not. Did I ever claim that?-never. The vented pilot chute is the extrapolation of very old technologies used in round parachutes. Did I claim to invent the idea-No. But we did a lot of research and tested numerous designs eventually releasing something that is not only vented but uses some other unique design features to enhance it's stability. Contrary to Dwain's assertation that Gravity Sports introduced the tuck flap on the shrivel, we were first to test and introduce the idea two years before GS or BR but even in our literature we do not attempt to lay claim to it because god knows someone probabaly did it 30 years ago on a pilot rig or a handbag:-)

My point about "copying" vs "inventing" is probably best summized by an Ad I recently saw in Parachutist. The Jump Shack is selling a canopy with a new leading edge configuration. It's identical to a skydiving canopy I designed and tested almost 8 years ago. Did they copy me? No. Did they draw the same conclusions about how to improve the performance of a canopy? Yes. That is the whole point here. If one thinks about ways to improve the equipment and then invests the time, energy and money in researching and testing those ideas it's commendable and we all gain. If a new standard is set, the next generation of product will build on that. Thats how we got from bottle rockets to the Appllo missions.
Conversly, putting a quick spin on someone elses idea and bringing it to market with inflated claims in an effort to earn a buck is...well, it's ethically wrong; but still extremely common. (BTW this is why I resopnded originally, because it was insinuated that our vents were just that.)

So back to your vent/valve question. Why didn't we release auxiallary inlets in 1996 when we began with the idea? Two reasons:

Our canopy at the time (the Mojo) had excellent low-speed inflation and pressurization characteristics and did not see a marked improvement with vents. This was evidenced years later when a customer (against our recommendation) put vents (no valves) into a Mojo and later decided it hurt performance more than it helped. He converted it back.

The second reason was that in 1996 a Mojo was $895 and BASE mfgs competed less w/ one another but more with new and used skydiving gear that was avaialble for less. At over $1500 for vented /valved canopy we didn't feel the improvement warranted the cost nor did we think customers would be able to justify the price tag.

With reference to your question about patents: Why would someone patent a life-saving device?

Patents are not about exclusivity, they are about ownership of intelectual property. License agreements don't have to even come with a cost but patent infringement claims start at triple damages.

Patents don't prevent the use of an design or idea, they preserve the origin. (Interestingly, included in their wording is credit for those that did prior work in the same area.)

When a person or company invests the time and $ in an idea and then markets the concept, the patent keeps the competition from taking a shortcut to the same end. Hopefully, with the road block to plagiarism that a patent presents, it also encourages further innovation.

Why Adam, I'm so impressed! I've often wondered when BASE manufacturers would finally take notice of the significant contributions that fashion has made to the sport! ;)

Tom the Alabama man,

>When BR was testing the first Vtec canopies, we tried several locations and sizes before the final design was decided upon.

I was there when BR was testing the vents...I guess that makes us "we" because we were at the test site at the same time, I videoed the initial test drops, and I threw in my 2 cents on where I thought the vents should be located. I way in no way compensated for being there... Does that make us "we" or not? Slight grammatical error and thank you for pointing it out. I really should re-read these things before I post them...

Jim,

My point was that you are deeply involved with BR, and there is absolutely nothing wrong with that.

You are one of their primary test jumpers, you essentially get free gear from them (what else can you call it when someone hands you a rig and say "go put 400 jumps on this and let us know how it goes"), and they pay for your BASE trips to "show the BR flag" (your own words). Haven't you also taught first jump courses for them?

At any rate, this puts you in a relatively rare, and highly enviable position. You have the inside track on developments in BASE technology. Lots of us appreciate hearing about them from you. All of this is something to be proud of, not to try to deny.

When you speak on BR gear, you speak as an authority. This makes your words more, not less, valuable, and makes people more, not less, likely to listen to them.
