  1. Alright it has now been several years that both these engine modifications have been around, and used in skydiving. Any updates from people who have been using 1 or both? I still am having trouble choosing which conversion to go with. We are at a 4300 msl field elevation going to 18k msl every load in hot weather, so climb power is a priority. However, reliability is always important of course.

    Any new advise from experience over the years of having one of these conversions?

  2. It's not a big deal to buy the tools as you need them. It will get you started, and no matter how good of a "set" or "kit" you get, you're still going to have to buy things here and there individually for certain needs. So I say just start that way and build it slowly. I bought someone's old lot of tools and wish I hadn't. I ended up replacing most things because it was too old or used and broke.

  3. The slider was almost all the way open during the snivel. So my guess is that the slider draw strings are the style where there is 2-3" sticking out when fully cocked. Then when packing the slider probably wasn't cocked all the way and left something like 5" of draw string out. This loose draw string snagged on the main lines during opening and caused that side to fully collapse and get stuck as the slider tried to come down.

    Always try to leave as little draw string sticking out of the slider when packing

  4. I load my Crossfire fairly lightly at barely 1.5 and it still doesn't seem to handle turbulence well. At least not as well as the Sabre2 I had before it. I assume this is from the small nose openings and flatter glide. Those low loadings should probably be avoided as everyone had been saying. Stick with a Sabre/Safire/etc for a couple more downsizes to avoid this.

  5. It sounds like it is a canopy prone to bad openings. But that one looked like the center of the nose was shoved in too much and the slider pulled out forward. Causing a bunch of bottom skin inflation behind the slider and allowing the outer cells to inflate before the center.

    Thanks much for the video. I'm at 36 measly minutes but now will use your progression as kind of a goal schedule.

    What percentage of fan power are they pushing you with in belly, sit and head down? Just curious.

    I'm 5 - 9 and 140# and Orlando belly flies me at 72 to 77 %. Actually when they turned it up to 77 % I really knew it and got a bit nervous but handled it.



    Every tunnel is different, so the numbers won't give you much reference. It has been a little since I've been in there, but I think most flying for me ranged from 60-85% if I am in there alone.

  7. I would opt for a more traditional approach first and just wash it with water and Woolite like any other rig. Then move to another option if it still is bad. I would think a normal washing would take care of it pretty well though.

    wow!!! insane video! glad everyone turned out ok!

    ive always thought(was taught) if you are so low that you can't make it to the group then track off till pull altitude. any time ive gone low I would just leave. when I opened I was 1/4 to 1/2 mile away from everyone because I had more time to track than them. if you leave early and still cant out track your mates you need to go get coaching!



    If you end up low, you should work on getting back up first. But either way you need to stay with the group. If the plan was a belly jump, but you go low and track off, who knows if the group randomly decided to start tracking together for the rest of the jump. You have no way of knowing where they are. You need to stay with them no matter what they do.

    The ultimate root of this problem is getting on jumps that are too big and over your experience level. It is more fun to stick to smaller, more simple jumps with goals you can actually accomplish anyway. You will be able to learn and get better that way.

  9. Jesus. I don't even know what the "dive" was supposed to be. During the first part of the video everyone is just randomly wobbling around the sky like leaves. I assume they are inexperienced jumpers that were trying to get together? If so, it is a simple case of people who aren't comfortable/competent enough in freefall to jump with a group that big.

    Helicopter w/ rears!



    These are fun on toggles and rears. Just make sure you have a fairly docile canopy and do them above your decision altitude because line twists can occur.

    Perform a low speed stall, then right when you are about to stall and rock backwards, keep one toggle buried all the way and raise the other one up. The more you raise that toggle the faster it will heli, but it will be harder to keep it going and control it. They are easier to control on rears, but are fun on toggles too.

  11. I wouldn't wear weights while free flying. They help with belly, but you have so much range when freeflying it isn't necessary. And weight will make flying your body like that awkward.

    Ideally you want skin tight fast materials like ripstop. This can be expensive with modern suits. If you don't want to spend the money, your current setup shouldn't be that much worse as long as it is skin tight. But the answer is yes, a proper suit really will make a noticeable difference.

  12. It is the easiest way to cocoon a packjob and lay it down so it is ready to bag. We don't wrap reserve tails because they follow a much longer but cleaner packing procedure. No one wants to put this amount of time into a main packjob, so if you just wrap the tail around, you can lay it down and throw it in the bag quickly while only creating minimal downsides.

  13. Ultimately it shouldn't make any difference since you are pulling the lines from the previous stow to make a clean new bite on the other side of the bag. I can see it maybe taking a little more time to get things organized with each stow. I like how they are nice and straight and ready to go if you grab sections as you walk the bag up.

  14. What method do you use to narrow the canopy after laying it down?
    Are you making sure the lines go to the bottom of the tray and not tightly wrapping around the reserve tray corners?
    Always make sure you aren't hooking any stray lines on a stow bite.

    Shit will happen more often on tandems though. Lots of lines, lots of canopy, and a first time passenger. However, if you run into problems on your main too, assuming the lines are all in trim, you could be doing something weird. It should be easy to spot though. Have your had others watch your method?

  15. Your normal skydive gear is ideal, so you are comfortable and used to it. However, if you don't want to bring anything they will give you a baggy student suit and helmet/goggles to use. I would bring your own jumpsuit.

  16. The best thing to do is to have no expectations. Just show up and take it one 10 minute session at a time. Don't worry about what you learn or don't learn in your trip. A relaxed and fun environment will lend itself to the best learning. No matter what progress you have flying in that damn tunnel is the most fun you can ever have!

    That flossing can wear the attachment tape on the d bag. Another method is to use the closing pin to pick the broken band off the bag. Always there and no chance on causing damage to the d bag.



    This is what I do. It works quickly and the closing pin is always within reach.

  18. The PD videos helped me a lot when I first learned to pack. Really watch the videos and what he does with his hands/arms/legs. One thing that helped me was that once you begin squeezing out the air for the s-folding process, you can never let go of the canopy and lose top skin tension until it is in the bag. Anytime you let go, air gets in and you lose clean folds.

    >Then as an additional piece of info, a slightly higher (but still reasonable and safe)
    >WL will be able to handle staying inflated with bumps in the air better than a lower WL.

    And a collapse that would be a minor inconvenience on a light WL might translate to a simple direction change that would be fatal on a heavily loaded canopy.



    You are right. I didn't mean to come across as if I was saying it was safer to be on a smaller canopy. My fault.

    My DZ almost always has a turbulence filled wind shear layer around 2000ft. When I was jumping a 240, I would get bounced around through this layer a lot. As I made steps down I noticed less and less bouncing around. That is what made me say what I did. But I do understand it is much safer to stay on a bigger canopy and deal with a little bumps in the flight, than to progress too fast and injure yourself on landing. I apologize if it came out as unsafe and wrong information.
