    It seems to have problems with end cell closure at ~50 seconds.
  2. Hellis
    I believe you are correct. The risers are old and are not built to 1998 specs. When I removed the confulence wrap, the stitching holding the loop was not "correct". Looking at my picture, the seams was straightstitches from left to right, and I would guess only 20-25 of them was on the loop, the rest was in the area around it.
  3. Hellis
    Not perfect but OK. It was though going trough all those layers..
  4. Hellis
    I thought of that too, it won't look very nice. So I will rip the seams and see what's under it. It can't be worse than ripping my own seams

    Does the placement of the "free ends" of the loop make any difference? The current loop is placed where they normally sit, but instead of ripping up the seams and removing the old loop, can I just cut the loop of an stitch the new loop higher up on the riser (closer to liks).

    Thank you both very much. My plan is to basicly lenghten it to a few mm more than what a new pair of risers is. The riser due for modification is very old and I believe, if I recall correct, risers lenghten by time and the distance between the rings get longer thus the loop seems to shorten. The plan is to have room for two cutaway cables in the loop.
  7. Hellis
    If you lenghten the loop holding the 3 rings will that make any difference on pullforce to cutaway? I'm guessing a longer loop will make it slightly harder to cutaway because it will shift some of the load from the rings to the loop. Is that correct? The loop is currently so thight you can't use the metalloop of the housing. My plan is to replace the loop with a longer loop. The risers will not be used in skydiving again.

    I have always thought balloonpilots don't want to go higher as people jump off. And how exactly do you recommend to pack for a quicker opening and beeing a reasonable idea?
  9. Hellis
    Before you pack for a quicker opening, talk to others who has made balloonjumps in the area. We generally exit at 2500-3000 m, which will take us to terminal velocity.

    Believe it's tax on imported stuff. Not the actual deliverymethod that is the problem.
  11. Hellis
    Correct. But in my opinion, having it on main only you will probably notice it time and you can "inspect" it at every jump. Unlike the AAD battery, which if it leaks, could damage your last chance. Yet there is no worries about that?
  12. Hellis
    Here it's C-licens, 200 jumps. I believe there is 20 accuracy jumps required for C. And I agree 50 is very low, and asking for a place without limit is asking for trouble in my opinion. But I guess it all depends on the terrain in the area.

    Rental gear and student gear might be a place were there could be a market.
  14. Hellis
    I believe you are both correct. The big issue is that the device already excist. However nobody uses them, why is that? I believe it's because non of the, probably thousands, of devices already on the market is because non of them is directed towards skydiving. All of them have something working against them. Could be size, weight, batterytime, range, ease of use, etc. What's in common with most (if not all) of them is the mounting problems. They all are associated with "you could probably...". And for most of the skydivers that's not good enough. What you need is a design that makes it easy to mount (preferably by a rigger), easy to turn on even if it's packed inside the gear, ok batterytime, a range that means you can find it easily, waterresistant. And then to an ok price. Most skydivers probably don't cut away more than once a year or maybe even every other year, is it worth it? It's a very though equation...

    Why such a rush? Wait till you can land the canopy with more accuracy and the jump will be more joyable instead of fear because you don't have the canopy skill mentioned by previous poster.
  16. Hellis
    How big intrest is there in such a device for the main canopy? I have been thinking of starting to build something you can track the main with, but I'm not sure there is enough potential buyers. I think I have found a company that can build the device, have not yet contacted them. As I see it the biggest issue is the batterytime, how little batterytime would be "ok"?
  17. Hellis
    It really doesn't matter. Even at 50 Mbps recording bitrate it's still only 25 Mbps when you play it (60 fps video played at 30). In my opinion, if you have the power in the camera to record at 50 Mbps, play it at the same rate too. Sigh... as always with you. Why do you think we are taking about Protune? The recording and playback bitrate is the same on GoPro
  18. Hellis
    Still don't get it?... In slow motion, the audio does not matter. But we are not talking about slow motion, we are talking about higher frame rate played back in normal speed. Also regarding bitrate. Sony has a bitrate of 12 Mbps at slow, and 24 at sslow. Not very impressiv in my opinion. As far as I know GoPro has a bitrate of 30-45 depending on setting. So your argument is not valid.
  19. Hellis
    Agree, but with a camera that record in 50, 60, or 120 p it's possible. And as far as I know, that is what this camera is competing with. Other cameras in the same size and function that can handle the framerates mentioned above in "p" with sound and with "normal" playback. I agree that it CAN be a user error, but in my opinion it's not. It's a crappy setting in the first place that makes the user have to choose a lower framerate just to get a video worth having.
  20. Hellis
    I agree that the sony is useless because of it's slow motion. But not useless in skydiving because the sound is most of the times not needed, but for every other use than freefall fotage. If I want to video skydiving during the day and use 120 fps and then during the evening want to video something else the video becomes useless if I forget to change to 30 fps. As posted before, let the user set the fps while editing. I can't see any use of video without sound. Barely useable in skydiving. Apart from that, ok camera. But because of this big drawback I no longer have it.
  21. Hellis
    Yep it's a common misstake. The jumper should not have to adjust to the canopy. The canopy should always perform as I want to, not how my arms act. Croc, you could cut a few holes in the canopy to counter act the flare problem with the canopy.

    I sewed on a few extra pockets to my gearbag. I found a picture of the type of gearbag I have, not the same color though... http://www.rockskymarket.com/2104-thickbox_default/gear-bag-pink-turquoise.jpg And the front pocket has been devided in to three sections. Inside the large compartment I have sewn on two pockets. They are sewn on to the "wall" where the diagonal line is and is the size of that "section". (from top of bag to top of outer pocket, and from left to right) The only thing I regret was to use black fabric in a black bag, and black zipper....

    It's still more than the average 'normal sky bridle' of 6-7 feet. I just meant all bridles are not the same and 'wingsuit bridle' depends on the sport. Just like "bidle" in crw is, I don't know, 4feet, maybe 5?
  24. Hellis
    Do you know the standard bridle in BASE is 9 feet? And that the "extra long bridle" used in skydiving is 9 feet? Extra long bridle in BASE is 11 feet. Wingsuitbridle in BASE is not the same as wingsuitbridle in skydiving.

    I agree a canopy does not need to have crossports, but they make the opening easier. I have a BT Pro and as long as the end cell closure is even, it's not a big issue. But if I only get end cell closure on one side the canopy dives very steeply. But isn't the crossport patented or something? I have a slight memory of I heard old canopies was made without crossports but with markings where to cut because of 'some reason'. Maybe I remember wrong or heard false stories.
