I was thinking about the opening sequence with my idea. Normally the container/jumper is pulling the lines from the canopy. When this is happening, the risers are out and the lines are being drawn from the canopy. This gives the jumper a chance to drop a shoulder or go head down, which will give input to the canopy left shoulder down, pulling left riser, pulling the canopy to the left, off heading. Theoretically, since the canopy is pulling the lines from the container, it doesn't have the force from the jumper pulling the lines out with the risers. Wouldn't the canopy begin inflating before the risers are pulled up and loading the jumper? If it begins to inflate prior to the jumpers body position effecting the risers, it should inflate onheading due to the separate line stows and the canopy should have already infalted enough for the jumpers body position to not matter much when the lines fully stretch and he/she is loaded with pull force of the canopy. Let me know if I have thought to far into, or just totally off. Thanks. Dale ~Dale

If I had the extra money I would be more than glad to pick up a used BASE container and sew the flaps in and loan it to someone to try. I don't have the jumping experience to try it myself . Although sounds like you have someone in mind for filming already! Dale ~Dale

Unless someone wants to do the test drops , my only other thought would be a Remote Controlled Manakin. So you could flare instead of it slamming and rolling into the ground. A lot of work, but I would like to test with the real size equipment instead of a scaled down version, I don't think it would be as accurate. Dale ~Dale

It is an F111 9 cell, and it did have stainless steel grommets in the slider. Aren't the grommets on BASE sliders stainless steel too? Dale ~Dale

Why do you need them to "close" at all? Would just a loose flap work? Or even just freestowing the lines in two groups, one on each side of the pack tray? A loose flap could work although I really don't know. The reason I would design it with a closing flap, is a cleaner tray(lines won't push out), and it will help to keep the lines nice, neat and in place. As I don't own a BASE container, I am planning on trying to sew one together with existing parts as close as I can see from pictures, and using an old 7 cell cloud canopy I own. I could dummy weight it and test drop it from the cliffs at my local lake back home, or possibly a bridge around there. I really wish I could get my hands on Buster from Mythbusters though

The locking tabs are meant to be tuck tabs. Hell you could use velcro if you want. Those two extending tabs on the bigger flap are what I think of "Tuck Tabs". I can see body position affecting it with design still, but this could possibly fix a packed off heading, and if the PC pulls the canopy to an off heading. Here is another picture of what it looks liek with the lines stowed and the canopy laying on top. The Red outline is the canopy . Dale ~Dale

The part where I marked the end of the risers was kind of mistaken. I am not sure how far down into the pack tray they run, but run them as far down on the left side, then figure 8 on the lines on top of it, making sure that the last loop is going down and coming out from under the flap at the bottom of the tray. I will put another picture up, of what it looks like with the flaps closed and where the canopy would lay. Dale ~Dale

It may sound confusing at first, so refer to the attached picture. Also picture is not drawn to scale. Alright, trying to redeem myself from that last one, I thought of an idea to reduce if not get rid of line twists and 180's. The idea, is to stow the left riser and right riser line sets separately, to prevent any kind of twists. First taking the left riser line set and running a figure 8 in an up and down relation; up towards our heads and down to our feet. It is placed on the left side of the container. The same is done on the right. Then you have a long flap that folds from the inside to the outside covering the lines and two locking flaps that slide into slits in the container. The lines then meet at the bottom of the tray. Theoretically, you should have a very very slim chance of line twists or 180's. Let me know what yall think, I am curious to know on this one!

Ahh well, unsucessful idea . Maybe next time

I was kiting a canopy last night, and had the slider uncollapsed and quatered, it took some work to get the slider to come down at about 8 mph winds. When I collapsed it and tried to kite it, it came down almost instantly. This was around 8 mph winds. That is the background of the idea. The reaon I asked this question was from the kiting experience I spoke of above. I am not saying this is a full proof plan for anything, I just wanted to get it out there, and see what more experience and knowledgable people had to say. My idea for it, would probably be instead of the canopy just plopping open, it would have a slightly uniformed opening, being as the slider keeps the lines more organized and slightly delays the opening. Could this possibly reduce line twists too? Again, I am not speaking from experience, just a curious mind. Dale ~Dale

I see. Doesn't routing the brake lines through the slider grommets lessen the chance of a line over, as opposed to running the brake lines outside the slider? Dale ~Dale

I had an idea, it may be absolutely stupid and far-fetched, but I want some feedback :). What if you could do a Slider-Down jump with the brake lines through the slider grommets and the slider in the up position? My idea is using a collapsible slider, in the collapsed form. So basically you have a slider quatered against the stops but it is collapsed. This allows the brake lines to be ran through the slider like normal, but the slider won't do anything, but possibly make the slider down jump a tad smoother on opening. Would there be any benefit to this setup? Just thought I would share an idea. Dale ~Dale

Sorry for the trouble, I didn't mean to revive an old debate. I am trying to learn as much as possible from several sides of the spectrum :). Thanks for the links, reading through em now. Dale ~Dale

Very nice information, thanks for the link. ~Dale

Thanks for the information guys. So, deep brakes incase you have an off heading opening, the slower foward movement gives you time to steer away. Say you have a 180 and you wanna steer away, would you use the rear risers, pop one toggle and turn leaving the other still set, or pop both toggles and turn? Dale edit for thread title ~TA ~Dale

What do you mean "throw it over and jump after it"? Like a McConkey or a Tard? Thought of another question :). When people are doing a PCA jump, lets say slider down..... what are their brake settings usually set to? Do you want as little foward moment on opening(Deep Brakes), or do you use a shallow brake setting? Main question, is which leads to faster inflation? Thanks. Dale ~Dale

I can see the ease/convience of doing a PCA on an object you thought of freefalling prior. I forgot about not having an attachment point for a static line on some jumps, that kind of slipped my mind. Thanks for the information guys, I appreciate it. I believe that is all...... for now

I see, the PCA definitely adds another element that can possibly go wrong. Why do so many people still do PCA's? Is it that hard to rig up a static line? I see, the thought of falling, makes you more susceptible to letting go early in fear of falling. Makes sense. Thanks for the info

I see, thanks for the info and the quick response. What about static-line deployment? Do you fall further or less with that? Dale ~Dale

How far does one usually fall before being under canopy in a PCA jump? Watching some videos, it seems alot of people are under canopy by around 50 feet at the most. My perception of distance could be wrong since it is on video and not in real life, though. Thanks. Dale ~Dale

I would also like to second this motion. Ground Launching seems to be picking up, and it is hard for me to search and scim through all the posts about it. I would cut down on the number of ground launching threads in the wrong forums, and make it easier for access to information. Dale ~Dale

Completely uninstall it and reinstall from scratch, worked for me.

HEB, be careful now

Need.... game.... must have game.......... ~Dale

Yea, I just downloaded the new version and it crashes as soon as you load it . Dale ~Dale
