sheerflyz 0 #1 September 2, 2003 So, I want feedback on packing tandems with the roll method. Please list pros and cons to psycho packing tandem parachutes. Also, any articles referencing the topic would be helpful. Thanks, sheerflyz Quote Share this post Link to post Share on other sites
AggieDave 6 #2 September 2, 2003 My thought is... why? Let me talk about what I know, Sigma. I packed tandems for a good while before I became a TM, they open very nice when packed right, so don't need to chance anything there. When packed right they go into the d-bag with ease, so you don't need to change anything there. My DZ pro-packs tandems and uses the PD flip method to keep the lines in the middle, we have had no lineovers (*knock on wood*), infact, the only mal we've had in a year and a half (I can't remember the exact number, but its near 1000 tandems) was due to a different packer packing a step-through that locked the toggles down in the risers. So my take is, "Is it broke?" Nope. Then why bother.--"When I die, may I be surrounded by scattered chrome and burning gasoline." Quote Share this post Link to post Share on other sites

Jimbo 0 #4 September 2, 2003 QuoteMy thought is... why? My thought is... why not? A properly packed parachute, whether Psycho, PRO, flat, or what have you, will open predictably, and reliably. Some find it easier to control the fabric using the Psycho pack. If that's what works, then run with it, I think. On the other hand, many don't understand the Psycho pack, and therefore, fear it. You might upset a few TMs if they find out that you're Psycho packing, but I'll bet that they'd never know it from the openings they had. - Jim"Like" - The modern day comma Good bye, my friends.

AggieDave 6 #5 September 2, 2003 I've psycho packed my main enough times to know what its about, I just choose not to... What about the common things like bridle extensions? I wouldn't think that would be easy to do on tandems, or if it would even be an approved mod by the manufacture.--"When I die, may I be surrounded by scattered chrome and burning gasoline."

nightjumps 1 #6 September 2, 2003 Well, you don't say what kind of canopy, so my frame of reference is the Icarus Tandem (which gives me a woody). My biggest concern with psycho-packing the Icarus Tandem is the concern of the eight brake-lines on either side. There is no "setting" the brakes, so there is a considerable amount of brake line "slack." Flipping it over and then rolling it does not allow (or perhaps just doesn't give me the warm fuzzy) for good solid line order and line tension. I'm still a firm believer that line order and line tension are the most predominate factors when packing ANY canopy. For me, pro-packing allows me to ensure the lines are where they are supposed to be - as best I can. Quote Share this post Link to post Share on other sites
Jimbo 0 #7 September 2, 2003 QuoteI've psycho packed my main enough times to know what its about, I just choose not to... I know that you have Dave, I was referring to TMs (or anyone else for that matter) who aren't packing for themselves. As far as the bridle extension goes, I don't think that it's absolutely necessary, but would adding it violate any manufacturers warranties, would it violate a TSO? I suspect that it wouldn't, but I'd love to know for sure. - Jim"Like" - The modern day comma Good bye, my friends. You are missed. Quote Share this post Link to post Share on other sites
jdfreefly 1 #8 September 3, 2003 The only way you could put a briddle extension on a strong would be to have them do it, and I would be willing to bet they wouldn't. Combine that with the fact that you could not psycho pack a strong tandem without one, and I would say it is a total no go. It is my guess that strong would be very unwilling to alter their design in any way that wasn't done expressly to prevent a known malfunction condition. Methane Freefly - got stink?

Psycho packing Tandems is nothing new and can be done very easily without a bridal extension. Jump first, judge later. Because you are not intimently familiar with it and have some fears, the question was about experience with using the pack job. Chris Quote Share this post Link to post Share on other sites

Combine that with the fact that you could not psycho pack a strong tandem without one, and I would say it is a total no go. why??? i could add a extention very easily to a strong set 400. the attachment is no differnt than a pd canopy (just material, instead of a mettle ring like icarus), you would just put the extention around, and then sew it on. and why couldn't you pack it without one?? you can just pull the top skin out to one side or the other, and roll it up. no big deal at all. psyco packing is no big deal at all. i can't tell a difference in the openings at all, when i jumped a heatwave, or now that i have a vx. they all seam the same to me. i have packed a icarus tandem psyco packed, the tandem master said he wanted it done that way, so i did. i'm not sure why he did, but i just did what he asked, and hoped for the best (considering the brake lines being infront of the nose) later Quote Share this post Link to post Share on other sites
nightjumps 1 #11 September 4, 2003 Quote...and hoped for the best (considering the brake lines being infront of the nose) Exactly why I won't psycho-pack the Icarus tandem canopy. In fact, I won't even completely wrap the tail around it on a pro-pack. I start at the tail and only run a tight wrap about 3/4 of the way up to keep those stabilizer lines away from the nose also.

riddler 0 #12 September 4, 2003 What about legal ramifications? Seems to me that tandems are more likely to sue a DZ than jumpers. If a lawyer could prove that a tandem canopy was not packed according to manufacturer's recommendations, they might have a solid case for injury - even something minor, like whiplash. I don't know any manufacturers that recommend psycho-packing. Quote Share this post Link to post Share on other sites
