Re: [TomAiello] 1st Base Canopy?
In reply to: "I've always seen more available forward speed as alwayspositive".
You definitely have a valid point, a faster canopy has a wider range of possible speeds. It also enables better penetration into strong winds and has potential to generate more lift during flare. If two canopies were identical in every aspect of their performance only one had more available forward speed - then I would choose it. However, in reality if
two canopies have different forward speeds then they will also behave differently in other ways. There are many different factors that need to be considered when selecting a canopy such as - nature of landing areas primarily being used, types of approaches needed for landing areas, available height/time to set up for landing, type of jumps being performed, jumper's background and personal preference etc and how the canopy performs in these areas.
I do not believe it is possible to fly and land a Black Jack at the same speed as a FOX and if it were I believe it would take a lot of practice. Flying in brakes is necessary sometimes but it means you are deforming the wing and hence the more brake you have to use the less efficient your wing is going to be. I do not believe all canopies should have as little forward speed as a FOX, there needs to be a balance.
I have owned a Mojo but no longer jump one, not because of its forward speed but because it does not sink as well as a FOX with Vtec and it is sensitive to surging or stalling on opening. To date 6 jumpers in Oz believe the 5th upper control line on a FLiK/FOX make the canopy to difficult to fly safely.
In my opinion a faster canopy has the potential to result in the following disadvantages:
* Harder to sink at steep angles for extended lengths of time (as required
when sinking into a small landing area surrounded by 20ft trees)
* Landings with little forward momentum tend to be harder to achieve
* Landings with forward momentum require several steps to be taken when
touching down (more suited to landing areas without large rocks & not on steep slopes)
* Object strikes when landing have the potential to be harder
* Has potential to generate more speed in turns
* Potential to surge more erratically when transitioning from a deep sink to drive
* More difficult to establish ideal brake settings for various openings (slider down, sub-terminal slider up etc.) due to increased sensitivity
* Less time to make decisions while under canopy
In Oz the landing areas are primarily steep slopes or covered in large rocks and sometimes both. When your feet touch the ground you want as little
forward speed as possible. The landings I have seen in nil wind with the Ace/BJ indicated that the canopy planes out in the flare. I have not been in a position to measure the speed but when you hear the suspension lines whistle through the air, the thought of jumping one is Oz scares me.
There is an experienced Oz jumper who even believes a FLiK is too fast for our conditions. While I understand where he is coming from you have to
balance the overall performance of both canopies.
I am about to purchase a larger FLiK but I would be willing to change the order to Blackjack. I have considered purchasing a Black Jack in the past,
without the ZP composite, but decided to purchase a canopy that was more likely to fill my requirements. I would love to be able to jump other manufacture's gear and see if it possibly out performs the gear currently being used but I don't have to funds available to do this. I'm not interested in getting into a debate about which canopy would be best or
which gear manufacturer is better etc, all canopies work it's just important to know if it suits your needs and understand the flight characteristics of each.
Like I have stated in the past it would be good to see a wider range of gear used in Oz, but on the up side of one gear dominating the market the information exchange is great. Jumpers do own Black Jacks in Oz and maybe one of them will post how they feel. I suspect they would rather have a
slower canopy regardless of manufacturer.
This discussion is very subjective and who knows what the next generation of canopies will bring. Generally speaking, the current generation of new gear seems to lean towards being higher performance. As a whole I am not opposed
to this, there just needs to be a balance and care needs to taken that we don't go too far in performance. You don't have to BASE jump a 9 cell
skydiving canopy to know it may not be a good idea.
Tom as someone who has a lot of jumps on a Black Jack do you believe a Black Jack is likely to out perform a FLiK in Oz? I have come close to buying a Black Jack in the past and may consider owning one if you believe it would be a wise investment.
