  1. One small method to slow it down is to leave a quarter of the slider exposed. Explanation: When it is pro packed, and hanging and the noses are rolled/tucked, then grab the quarter of the slider that is outfacing and pull it outside the "bundle". Try it. This tip came from the PD 'main packing' demo at PIA two symposiums ago. I also have a Stilletto 170. (Older canopy) Same problem. about 1/4 of the openings are hard. I had it relined by PD and yes, the openings were a little bit better, but by no means did that eliminate the problem. I just jump it. I actually like firm openings, but not the hard ones. I stick with my Stilletto because it is such a great canopy. I by no means get "slammers"; just a bit harder than I'd like.
  2. Yeah... and if I can do the math in my head, if 5 cord at 40 each, 320 lbs for each "tooth on the zipper" if the threads are supposed to break sequentially. Of course, fewer pounds if the thread is a lighter weight or polyesther. I doubt it would accomplish the shock reduction function it seems it is intended to do. I agree it would probably just stop the falling 'tree stander guy'. However, to be fair, I am only an "armchair doubter". And, even though the cross stitch is strong if the straps are pulled lengthwise, it isn't strong when loaded = thread by thread. That's why they have confluence wraps on military risers. It would have to be tested with a couple of hundred pounds and enough length to get the breaking effect to work. Maybe it has been tested and works correctly? 200 lbs moving downward fast may be enough? Only a test would reveal it's design success or failure. I'm not impressed by the fuzzy /loose webbing. When the stitches break- if they ever do, the webbing will be ripped a bit too. (I'd kinda also wonder what the anchor would be to take such a shock. It better be good.)
  3. 1.1 ripstop will deteriorate in a year or even sooner. Waste of effort. Sunbrella is acrylic and yes, will last much longer, but it is very heavy, very expensive, pretty hard to sew and repulsive to the touch to put on and off. It is fine for boom covers for sailboats, and such, but would be too heavy and overkill for a car cover. I suggest their other product: Surlast. Much cheaper, easy to sew, and is kinda the standard for covers. It isn't as resistant to the sun as Sunbrella, but is pretty close. Just heavy enough to do the job, but light enough to be easy to handle to put on or off. We do some sail repair at the loft so I am familiar with both of these fabrics. Recommend you not go with Sunbrella.
  4. In the "Statement of Facts" I was looking for a particular "fact": (evidence produced in the case by expert testimony). What I was looking for was evidence that there was in fact - excessive noise. The gravamen of the Plaintiff's case. (Gravamen= the material part of a grievance) Since I only attended two days of the trial, I was very interested in reading the Appellant's Statement of Facts to find evidence of excessive noise. There was wordsmithed verbiage about 65 decibels and whether it was even a standard. There was a statement that the Purple Otter "could" produce 80 db's, yadda yadda, but nothing approaching what a trial judge would be considering to determine whether the Plaintiff's noise complaint was a valid claim. For the Plaintiff's case to be successful, I would have expected the following 1,2,3 to have been presented: "1. The decibel limit for noise considered to be a violation/ nuisance is 65. 2. The Defendant's aircraft exceeded the 65 db 3. Therefore our complaint is valid and justiciable." (In cases where a fact is not measurable, well, I get that) But, noise is measurable with a decibel meter - you either have it or you don't. Evidence of any other sort, such as "It bothers me", etc is simply a subjective statement, and the level of irritating noise, or the irritating nature of a type of noise varies from individual to individual. I don't even get, from reading the statement of facts, that there was even an applicable decibel standard. If there was such a standard, it doesn't appear that the Plaintiff's established it. "Plain reasoning thinking" says you can't win (or lose) a race without knowing where the finishing line is. At least that's how I view this brief. In short; From my reading of the Appellant's own statement of facts, the burden of proof for a nuisance lawsuit was not been met. I believe the trial court found that too. A perceptive and intelligent reader of this appeal brief, (And I fully believe the Court of Appeals persons are both perceptive and intelligent) in my opinion, should summarily reject the Appellant's contentions because of the Plaintiff's failure to carry the burden of proof. Further, since that minimal burden wasn't met, all of the damages awarded should be valid too. I get all of that from simply reading this brief and seeing their arguments. Keep in mind, all appeals courts rule, based upon the record. They are free of the drama's and emotions etc. that are necessarily part of the case before the original trier of fact. Hopefully I am correct on this.
  5. Ski and Councilman are correct. You count backwards from the midnight of the last day. 180 days. Period.
  6. Ethylene glycol is antifreeze. Propylene glycol: Is this spill kinda like putting antifreeze on nylon? Are they chemically related enough to compare? I would definitely contact the mfg to see the effect.
  7. I've packed a lot of C-9's and have never seen that. Whenever I've seen weird stuff I call the rig mfg and ask them if it is something they want to address with that rigger. Also; I wouldn't want anything to prevent air from entering the skirt on a non diapered canopy. Maybe the pilot is getting out really low?...staging is the last thing he needs.
  8. Clint: I don't know how to PM, but if you do, PM me your address and I'll send you a leg-mounted streamer pack to try out.
  9. Construction tip: Sew the hollow nylon tubular lengths to the leading edge of the flag BEFORE filling them with lead shot. Sew them to the leading edge with a double throw zig zag machine. It your rigger doesn't have that machine, use a very very wide zig zag. (If you fill the shot tubes first, it will be problematic to attach them to the leading edge.) You might message Airtwardo to confirm this flag design and get more tips. You can also use one big shot bag at the bottom, attached with a Rapide link. That is done a lot; but you end up having to use a much larger amount of weight than you would if you have a stiffened lead shot leading edge. You don't need to reinvent the wheel on this flag idea. It's been done and perfected before.
  10. Jethers, It doesn't take much weight if it is in the leading edge. I'd skip the scuba weight idea. Never heard of trying solid chunks of metal as flag weights? In my opinion=a very bad idea. Get standard one inch tubular nylon strap and fill lengths (kinda like long shot bags)with lead shot. Then double and triple (lay them side by side) as you get to the lower end. You don't need any shot near the top. Just taper by laying side by side as you go down. Doubt it would take more than 10-12 lbs . Probably even fewer. Might cover the weights with nice parapak installed tightly around the lowest shot tubes, just to cosmetically finish it off. I have made this setup and used it for years. Mine is 12x24. F111 for the red and white stripes. Didn't take very much weight and it flies nicely with a vertical leading edge. Neat thing about lead shot is that the little shot balls pack tighter and tighter with motion and stiffens the leading edge. Don't forget to make "joints" in the leading edge to allow it to be folded. Please stay away from chunks of lead to use as weights. If I might say so, your flag dimensions are kinda weird. 12x18? It will look almost like a short rectangle than a flag. Correct visual "look" for a flag with a 12 foot leading edge would be 22 or 24 feet. Your 12x18 will look somewhat cartoonish. Suggest you re-order.
  11. Councilman is correct. At one of the last meetings in conjunction with the PIA Symposium the FAA guy stated that rigs packed under supervision by the trainee are not OK. (Private gripe: Unfortunately, the FAA no longer has actual recurrency meetings where all can discuss issues-changes etc.. It's all done now in a "worthless-fakey, waste of time process", online.) Sorry, my gripe.
  12. Visited my daughter in new York. We drove to Saratoga to a rowing meet on the river. My daughter had her smartphone and (of course the river doesn't have an actual address), so she drove and looked at her smartphone screen, entered guesses of where the river might be (while driving) looked at the screen of her smartphone as much as the road ....I got irritated and said she is basically texting while driving, (not legal). I asked her to stop and we asked a local how to get to the river park. I told my daughter to put her smartphone away. Easy. We drove right to it. A smartphone is NOT the answer if you are driving and looking at it. And is probably illegal; or if not outright illegal, if you wreck it would almost certainly count as distracted driving.
  13. ...And "Jury Rigged" (sailing term) has degenerated to "Jerry Rigged" by those who don't know of the correct origin. ,,, And America's Got Talent". Absolute misuse of the word 'got! It should be "America Has Talent". Got is the most misused word of all. I mean, crimenentlies!
  14. ..knots are "crunchy"...??? Not getting this one.
  15. A Rapide is not a "Slink". Slink is a trademarked product of Performance Designs. A combo of the two words: soft links. Yes, as sparky said, Rapides are available at Paragear and the strengths of each are listed on the page.
  16. I made one that goes onto your left wrist. (All fabric; "soft" if you will) It has been used several times. When released the ashes form a spherical ball shape which is highly visible to watchers on the ground. Can be used over and over. I don't make them for sale, but can send you the pattern, etc. PM me and give me a mailing address. I don't do uploading stuff.
  17. Is there a source for the old movie "The Skydivers" WITHOUT THE WISECRACKING JERKS making stupid comments? Black and white movie uh...60's or so
  18. I doubt they post that stuff on their website for the curiosity seeker. I have packed the Paraphernalias and Butlers in my shop, and have seen and touched the Rigging Innovation Aviator at PIA. Similarities in designs. Brakes for opening and limited toggle travel are addressed in all three.
  19. If you did outfit a pilot with a modern ram air, and the [pilot has never jumped anything; would you allow it to have a standard skydiver brake release system and full range toggles? Or, would you install some kind of limited travel/half brake toggle system now used in Parapernalia, Rigging Innovation and Butlers?
  20. It is pretty clear that the decision to send, or not send a "post 2016" unit in won't have to be made until 2020. Kinda rushing it to put it as a poll question now?
  21. Wow, those were some fast openings for non-quick opening band canopies! I have never seen a 24 foot belly parachute without the QOB's. The one's I've seen were military paratrooper surplus. Al were so equipped.
  22. PEP rounds we see every day lack some of the features of military rounds: Quick opening bands, elastic vent collars, anti inversion nets, slider, etc. The 24 foot belly reserves you mentioned ( I presume) had quick opening bands. Butler has the break cord ties around the apex lines and at the lower end of the lines to keep the lower lateral band even (compensating for a lack of an anti inversion net. ) The pilot rounds we see are pretty old school, except for the diapers. I would imagine that a ram air would (on average) have a quicker opening time because the rounds in common use lack the quick opening bands and vent collars. Once they are open, they are (in my opinion) probably a safer bet for the 'untrained first time under a parachute' users, but the ram air folks are certainly disputing this. I'm not really taking a firm position on ramair vs round except for the joy ride passenger. Even so, the old school rounds we pack all the time might consider the features the military has been using for years to enhance quicker openings and prevent mals. There is a tradeoff of course. There always is. A quicker opening puts more strain on the canopy and the pilot and anti inversion nets add a packing difficulty. Butler's slider gizmos obviate the necessity of an anti inversion net.... and so on... Is simpler better? Good fodder for discussion.
  23. Although it it's embarrassing, I just remembered that all 3 of the mfg's canopies don't have releaseable brakes. So, my concern of one toggle being released, and then let go is something that is taken care of. It doesn't cause a problem as they do not release in the first place. They are just set at about 1/2 brakes and if let go they will fly straight. Nice. As what's his name already said.
