    Tailgates

    Working on it. It is the rainy season and I can´t repack inside my apartment.

    Tailgates

    "The question at hand is: Is there a simple, reliable method to help ensure that the slider will remain high and in place to restrict the opening both during packing and the chaos of opening (including the reported occurance of a slider dropping through the burble of the jumper), that would be applicable/effective in both terminal and sub-terminal deployments on a skydiving main canopy?" 1. Direct Slider control is the best method I have seen to reduce the risk of the slider being out of position during deployment. 2. Tailgates are only to promote nose first openings and reduce the risk of lineovers. Which are rare slider up (we have the technology to clear lineovers, slider up or down). The slider will do a lot more to reduce lineovers than a tailgate. A tailgate on the slider doesn't control the slider. Many of us use the original "slidergate" concept. That is both center C-lines attachment points or tailgate ports with rubber bands that group the inner C and D lines all steering lines all together. The slider is held in the rubber bands and when the slider is released, it releases the grouped lines. I could draw you diagram if you want. Take care, space edited to add: A magnet or snap at the apex of the slider to the bottomskin would work but I am not sure of its lifespan. Magnets to be strong enough for this purpose would have to be pretty strong and could cause material damage when connecting them. Snaps could have similar problems when releasing. Maybe a tab system could work better for Direct slider control.

    Tailgates

    I am against tailgates being installed on the slider. I have seen quite a few skydiving mals due to the drawstring of the slider getting hung up in the cascades. The tailgate installed on a slider would be apt to the same malfunction. Take care, space

    Tailgates

    "PS - I'm NOT set on one method or another, mostly trying to get/keep the discussion going for this off-label use." A method for what exactly? What are you trying to address? I saw a video before, of a pilot chute assist from a low jump (slider down) normal tailgate, hang up. Of the 4 reported, they were all pilot chute assist deployment. No freefall reports of a hang up. As for slider types, I have done it on all types. A tailgate is used to promote a nose first opening and linover risk reduction. A valuable tool if jumping slider down for some. Slider up, you introduce the possibility of the tailgate on the slider getting hung up in the cascades. I would not jump that setup on a BASE rig. The slider tailgate doesn't hold the slider in place because canopy slump (aka, centercell extraction). The relationship of the slider to sliderstops is not as static and the lines still can travel through the slider and tailgate. I hope this helps. Let me know if what I write is unclear please. Take care, space

    Tailgates

    Not @ fcajump, Tailgates are to reduce the chances of lineovers and to promote a nose first opening. This implementation has only a small effect on opening speed. Slider control, has a much bigger effect on opening speed. Here is a BASE video discussing Slider control. https://www.youtube.com/watch?v=nciajWdFd9c. Take care, space

    Tailgates

    "For me (having not used either technique) of a slider attached tail gate is it would seem less likely prone to hangup on subterm h&p." Though a hangup is a hang up, which hang up do you mean? The tailgate on the descending slider hanging up in the cascades (an added possibililty), or not releasing due to subterm deployments (highly unlikely)? Remember that gates are for lineover risk reduction. Slider Controls are for keeping the slider up against the slider stops during extraction of the canopy in the deployment sequence reducing the chance of an incapacitating opening shock. The rubberbands wear out way faster than the material. I have never seen or heard of the slider being damaged by repeated use of the Direct Control Method. The prioritization of risks places this scenario way down from the scenario of an incapacitating opening. Take care, space

    Tailgates

    I am a long time BASEr, BASE Instructor, Mentor and Rigger. In the context of your question, I think the knowledge that you are seeking is about "slider control". Check out this video https://www.youtube.com/watch?v=nciajWdFd9c about "Direct slider control" and "Indirect slider control". Tailgates and the different versions of the slidergate are for reducing steeringlineovers. This is not a common problem slider up. I personally would not jump the slidergate shown in the OP video. There is a possibility of the modification getting caught in the cascades. I see that a common myth is reposted on this thread. That BASE canopies/pack jobs open faster (Snappy openings are part of BASE). A good packer can control the opening speed to a large extent. If one wants snappy openings, That is achievable. Same for comfortable openings or snivels. Getting to that level of packing skills can be a challenge but it is doable. If anyone wants to carry the discussion of Slider control or/and tailgates, I would be glad to impart my knowledge. Take care, space

    Packing a new canopy ... flaking problem

    Here is a diagram of a flake job. Viewing the bottomskin as it is hanging from your hand. It is for a 7 cell but it is the same principle as a 9 cell. After doing the best job in the stand up flaking. I lay it down, walk around and check that the packing tabs are grouped per line group, raise the tail and group the line groups together while pulling out the material. As the other poster stated, the pack job gets distorted as it hits the airstream. So you want, as much as possible to reduce the variability by doing the putting the same pack job in the bag. Make sense? I know this is similar to a BASE packjob flake, but it has very little influence on opening speed. It is the same as a reserve flaking. Which is flaking to the max and not getting lost on the C-D-Steering line groups and material. I hope this helps. Take care, space

    Packing a new canopy ... flaking problem

    What effect does it have on opening? For BASE jumping pack jobs, a lot of us use the line attachment point groups, and place them in this order. abcds sdcba. Try that if it is irritating you. If you are having good openings, then it is only an irritant. Also, see if the pack job you pack comes out of the bag the way you want it. I hope this helps. Maybe i have a diagram of a flake job.

  11. Ponder the effects of flight of the sign if one grip is released. Basically, one would have a helicoptering blade at shoulder and head level. The other risks pale in comparison. Do the flag and/or photoshop would be my advice. Wear good gloves if skydiving either method. I hope this helps. Take care, space

    Bernina 217 decorative attachment timing.

    I am busy at the moment buit can get back to you later. I have a 217 also. I need to know which wheel in the game have you? there is a number on the cog. give me this number. and also tell me the millimeter stitch width. I have a 217 N 08. the last 2 digits are the millimeter spread stitch width. and do you know how to put it in time? take care, space

    Triple Fatality - Ludovic Woerth

    You should have seen the uncut version. The sponsors forced them out of the aircraft at gunpoint. That is probably why they were feeling uncomfortable. Or also it could have been that the riders felt uncomfortable because they knew inadvertently that you would be jealous. Take care, space
