    Hello all!
    As some of you have heard, over the last few months, I've been planning out the new ARS parachutes, called the "ARS Extreme Parachute Series"
    This new series of parachutes will be strong and fire resistant.
    These chutes will be in the colors red and green, and are made from ripstop nylon, and Kevlar shock cord, for added strength, and to make it fireproof.
    Also, I take the time to sew it right, so that you have a good quality product for a reasonable price!

    What sizes?
    9"
    12"
    15"
    18"
    24"
    30"
    36"
    42"
    48"
    60"


    Q: Prices?
    A: idk yet, but I'll be sure to update you as soon as I know.


    Q: When?
    A: In the next week!

    Q: Who?
    A: These chutes are designed to be used by all rocketeers! Whether you're launching a small model rocket, or a big high power rocket, we make our chutes to be used by all rocketeers, with our flexible line of chutes, ranging from sizes 9" to 60"


    I need your help!

    Please answer the poll! Your opinion counts!

    Why do I need your vote?
    Because I need to know how much of a demand there is, and I need to know how many to sew this weekend.





    Thanks,

    You want to remember to say "fire resistant". Just my $0.02c

    Two hundredths of one cent? Don't be so hard on yourself. I'd give you at least a penny.

    I wouldn't say fire resistant,somewhat fire proof or anything relating unless your just refering to the kevlar parts, and did you mean kevlar shroud lines instead of shock cord? To answer your question when i try a new parachute I'll buy in the 9"-24" range before buying larger ones.

    Question.
    Is cutting a hole to the very top of the parachute help it descend faster (due for weight sizes and heights)? Or is it helping the wind aerodynamics push the rocket upwards more because of the wind shaft you just created? Im puzzled please answer.

    Andrew, do the Kevlar shroud line really add anything (except cost?)

    Are these jut a flat cut piece of material (circular or hex / octagonal) with the edge hemmed?
    (You can probably save the edge hem labour by cutting the shape with a "hot knife")

    Matt, you are referring to a 'spill hole'. Cutting a hole in the middle / apex of the chute canopy. Yes, they do help with swing, but does reduce the effective drag the chute is to have. I believe we all prefer a chute with a hole in it, but will take what we can afford! (Nylon chutes with a spill hole are usually sewn from many panels)

    The Kevlar is stronger than the other materials other companies use. And since Kevlar is stronger, that means it can be thinner and can weigh less, making the chute more compact.

    Besides, Kevlar is much more fire resistant . Yes, it's more expensive.

    I did many many tests before making these parachutes, and the results were absolutely stunning.

    When I exposed the shroud lines of a competitor's chute to a flame for 5 seconds, it literately disappeared.
    When I did it to Kevlar, it took 18 seconds for it to disappear, making the Kevlar much more resistant to the flame.

    After I did strength tests between my chutes and my competitor's, mine could withstand much more force.


    Also, to answer your question regarding the shape of the chute, yes, these will be hexagon shaped chutes. Yes, a hot knife can work, but sewing the edge with a nice clean stitch is much stronger. Even though it'll take more time to sew it, I'm more worried about the quality of the product than I am the time that it takes.

    I do not release a product without making sure it's durable, and reasonably priced.





    Thanks,

    The canopy is still nylon, so this is pointless. If you get fire to the shroud lines, you burn the chute anyway.

    OK, well that's true.
    However, our chutes are stronger than our competitors..

    How do you figure? Nylon is nylon..you are only as strong as your weakest component.

    I tested some basic Alpha rockets today with two types of parachutes; one being a regular 12" parachute, the other being a 12" parachute with the top portion cut out for a wind channel

    Results for today were kinda all over the place, for 12mph wind the regular parachute did indeed have a longer aloft time but it went according to the wind direction
    On the other hand the parachute with a hole cut in it did almost the same thing in the same wind conditions with the exception of it drifting far less longer.
    But one thing i saw was that some of the parachutes with a "spill hole" didn't go with the direction of the wind they mostly caused the rocket to descend in a spiral but this was not exactly helpful when it came to spot landing.

    So how can i improve my Spill hole? make it wider or less ?

    Becuase I take the time to sew the chutes correctly.

    Some parachute manufactures hurry up and rush, due to the high demand of their chutes, and don't sew it very well.

    I once bought a chute a few months ago, from a parachute company (That I will not name)
    I got it, and it was poorly sewn. The thread was still hanging from some of the stitches, and the stitches were messed up and misaligned. I was stunned that I spent $30 for this chute, and this was the quality I received.

    This inspired me to sew my own chutes, with stronger material (Kevlar) and to sew it better.
    After doing extensive research, and sewing a few sample chutes, I finally came up with the design that I was looking for.




    Thanks,

    Hmm, that's odd.
    Whenever I made spill holes in my parachutes, it would just descend quicker. I can't say I ever experienced the rocket to spiral down.

    I apologize, but I'm not sure what would cause this.

    Perhaps someone else may know the cause.

    Why do you think your chutes are stronger? I will put up a Top Flight Recovery chute against yours anyday. Go a head a put them out on the market time will tell how strong they are. Good luck. Go for it.

    Umm im talking about um 12in recovery chutes made primarily plastic Estes parachutes the only ones that if you dont put wadding in they melt them type.....

    For the fact that the rockets spiral is a dead end problem for me as well.... But i do know that "Spill holes" Have a tendency to actually stay aloft a long as a regular chute ( this depends on wind direction and speed) for overall concepts im not entirely sure how i can improve the decent rate of my rockets, (lets member these Alpha rockets only weigh like 45 grams)

    OK, challenge accepted

    I'll send you one free of charge to compare to top flight's chutes, and believe me, you won't be disappointed in the quality of the ARS chutes

    Yeah, I knew that you were talking about a 12" plastic chute

    That's what I was referring to

    Only positive I could see with the Kevlar shroud lines is you wouldn't have to wrap it in the blanket, might save space that way. I told my lines inside my chute, and as much harness as I can fit, then wrap it with Nomex.

    I have parachutes from most of the manufacturers and all have been great. One I was really unimpressed with on a smaller chute but the larger one is much better.
    Off the top of my head: Top flight, Binder design, spherechutes, rocketman, rocket chutes, LOC, PML, DinoChutes, all have been great.

    I may be willing to try one out. I need an 18" for my Mini Pike.
