  1. Nahhh... Landing the suit even without a fully inflated parachute, with a human inside, and from higher than 2ft is easy. Being able to do it again after the first landing, now that's the hard bit!
  2. After a quick look through the Parachutes de France website I couldn't find any SB's that would apply to your rig. You might want to go through them in more detail yourself and/or with your rigger. I jump an Atom Legend myself, and I've been very happy with it. That said, I just replaced the reverse risers with a set of Aerodyne Miniforce risers. Most non-reverse risers should work on your Atom. The Miniforce risers have additional things to consider when installing them on anything else than an Icon; check with your rigger.
  3. I've seen that problem solved by cutting the tuck tabs off...
  4. Nice looking rig. In the last pic, there seems to be a gap between the pilot chute top and the side flaps of the reserve container. If that's the case, your reserve closing loop is too long or the bulk of the reserve has been distributed incorrectly. The pilot chute top should sit flush on the side flaps, or below the side flaps, but never above. You shouldn't be able to stick your fingers below the pilot chute top.
  5. Does the higher aspect ratio increase the chances of line-overs(less distance for the brake line to cover to get in front of the canopy)? I've heard this mentioned as one of the reasons BASE canopies are 7-cell.
  6. I have packed SET400s for a few times, but just couldn't remember how they work. I do remember the rubber band trick though. The DHT manual doesn't mention dual brake lines, are there different models around? The illustration in the manual(attached) looks like the brake line splits in two at the locking loop?? edit to add: The manual does mention not setting the inner brake lines at a later stage.
  7. I don't know. It was changed, IIRC, about a year after the introduction of the Sabre, so there wouldn't have that many canopies of the original design around; I've never seen one. I have seen, just recently, a 1993 model Sabre190 with 6 brake line attachment points, and a single brake line with 4 cascades attaching to points number(counting from outboard) 1,2,3 and 5. Does anyone know what the deal with that would have been? Old lineset installed on a new canopy? Was there a service bulletin to mandate/recommend modifying the existing canopies to the double brake line system?
  8. The brake line configuration on Sabre190s(and bigger models) was changed to the current double brake line system to fix opening problems.(Poynter's vol2) I don't have the manual handy but I _think_ it was to prevent hard openings. A new line set for a Sabre190 will include the double brake lines. The double brake line configuration on a tandem canopy is meant to make steering the canopy less tiring; the TI steers the canopy with one set of toggles and picks up the other set only for landing. The double brakes have no effect on openings since both brake lines are set. This assuming that you set the brakes at all! On RWS EZ and Sigma mains both brakelines are set. Likewise on Strong T520. On Icarus and Precision tandem canopies NO brakes are set. Other tandem canopies may have a system similar to the big Sabres but I don't know of any.
  9. Have you considered getting a couple of rolls of different coloured adhesive ripstop patch tape, and building the logos out of that? Depending on the logo it would take some work but it would definitely hold for one jump, and probably for the lifetime of the suit if need be. The downside is that the tape may or may not leave a sticky residue on your wings when you remove it, and the glue may or may not damage the fabric over time.
  10. Me and another jumper going up in a Cessna(yes, just the two of us), planning to do a 2-way from around 3500', and then deploy in place, him first, then me. Me: "Oh yeah, if you happen to need to chop, first make sure I'm not directly below you when you do." Him: "Why would I need to chop?" -"Well, you know, parachute systems just sometimes fail to work as intended." -"Yeah, ok." We jump, he dumps, I fall away, I dump a few seconds later. I land, and see two parachutes in the sky. For some reason, my first though was "My god, the pilot jumped too!". I then realized what happened. He lands the reserve, and tells me that after opening, for some reason, the canopy was turning and that he couldn't control it. He decided to chop, remembered what I said, checked to see me flying my canopy well to one side, and went for the handles. Luckily, on his next jump(off a local A), the canopy opened just fine.
  11. >So, should you wipe off the silicone before reassembling the system? Yes. According to some instructions "Only a thin invisible coating should remain" or something to that effect. I just keep wiping the cable with a rag or tissue paper until nothing comes off the cable.
  12. Interesting idea. I was actually thinking of doing some pull tests myself(mainly to see how my results compare to the different numbers Aerodyne and RWS came up with), and an observation on the "cable distortion" would be easy to include.
  13. Yes. Which is, IMO, the wrong way. With my Atom toggles, I have to pull up, then down to release my brakes. It's by far the most secure velcroless design I've seen.
  14. Here is a chart on 3-ring loads and pull forces that I compiled from information available on the RWS and Aerodyne websites. In short, the force on the loop depends on the load hanging from the risers and the type of 3-ring release used.
  15. I'm not a big fan of your toggle setup. I'm sure it's been tested thoroughly and all that, but basicly the only thing keeping the brakes set is a single steel pin that's pointing the "wrong" way. What I mean is that I can easily imagine a rapidly descending slider knocking a brake loose on deployment. I do like the Miniforce system and the hard housings; so I bought a pair of your risers and modified them to take my original Atom Legend toggles. If you could offer the same kind of toggles as an option on Icons, I don't think I'd have to think twice about what container I'm buying next...
  16. Last weekend one of our tandem instructors had a rather interesting jump. On exit, the side connecting strap slipped to full extension. Video shows the strap being correctly adjusted on the plane. The instructor noticed this immediately after exit and managed to deploy the drogue while stable. At pull time, the rig was floating way above his back(see attachment "freefall_low.jpg"), he couldn't immediately find the primary drogue release handle, and so went for the secondary. We had earlier noticed that the MLW adjustments on that particular harness(RWS Sigma passenger harness serial#1360) seemed to slip slightly every now and then, but this hasn't been a problem so far. In fact because of the ease of adjustment it was everyone's favourite. The harness has approximately 150-200 jumps on it. Upon inspection, we found out that the webbing(type VII) on this harness(serial#1360, DOM 6-Aug-04) was thinner and more slippery than on an earlier version(serial#841, DOM 14-Feb-03). Also, the hardware was slightly different. All hardware was made by Bourdon Forge, but at different times. The anvil on the friction adapter(DOM 04-03) on the MLW was a different shape and had a polished finish on it, unlike the matt finish on the older(DOM 07-02) friction adapter on the older harness. See attachment "mlw_adapters_low.jpg". The friction adapter on the side strap(DOM 11-03) also had a different shaped anvil on it when compared to an older one(DOM 06-01). Both of these had a non-polished look to them. See attachment "side_adjusters_low.jpg". Harness elastics on the harness are in good condition and were in correct position when we tested the harness on the ground. This made no difference to the slipping of the webbing. I'm not sure whether the problem is with the webbing, the hardware, or the combination. Has anyone else experienced this problem? Any suggestions on how to fix this? The harness has been taken out of service for now. Re: "Contact the manufacturer" - I've sent Bill Booth a PM notifying him of this post.
  17. Totally off topic but: The Sabre was introduced in May 1990. Parachutes De France introduced the Blue Track in late 1989. (Poynter's Manual vol 2)

    PDF help

    >How can I edit a .pdf document? With "Adobe Acrobat". Which isn't the same as "Acrobat Reader" that is installed on most Windows machines. "Acrobat Distiller" installs as a plugin on MS Office, giving you the option of "Exporting as PDF". If you have the original file (.doc or something) you can open it in OpenOffice, edit to your hearts content, and export as PDF. OpenOffice is free. And Open Source. I don't know of any (legally) free programs that could edit pdf's, but they may be out there.
  19. And then wonder "How the hell am I going to adjust the harness so her bum doesn't hit the ground before my feet?" Ugh.
  20. Hmm. So, when you're fat enough, one stomach isn't enough. I didn't know that. The one on the right obviously isn't quite there yet.
  21. This is not recommended by any container manufacturer. Someone from Sun Path did recommend dry cleaning to a friend of mine just a couple of weeks ago. More in this thread The thread also contains one very good piece of advice: When dis-assembling your rig for cleaning, remember to cover all pieces of hook velcro with an extra piece of loop velcro!!
  22. The first thing I did when I heard there was a service bulletin out was to go to the Aerodyne website. I couldn't find the SB. I still can't find it there. Am I just being stupid or did Aerodyne actually only publish their SB on DZcom?? edit. Right, I found it now under "Technical Bulletins". But I'm pretty sure it wasn't there when I last checked... re-edit... The document itself still says "Safety Bulletin" and "Mandatory". And there are at least to versions of the pdf, one on DZcom and one on the Aerodyne website. Content seems to be identical though.
  23. FAR this and FAR that. How about thinking outside the box for a bit? Or rather, outside the US... I'm sure there are plenty of countries that have little or no restrictions on parachute ops. Or parachuteless ops, as it may be.
  24. I chopped the wings on my second or third BM jump. I was going for the pull, looked for the handle for a bit and then suddenly went into a head down spiral, probably because I let the leg wing open. I resumed flight, realized that I was below my planned opening altitude, and didn't want to repeat what I'd just done. So, I closed my leg wing, chopped the arm wings to get them out of the equation, and deployed from a regular body position. Other than that, I've once chopped the arm wings after opening to get out of linetwists.
  25. "All models of SST/Racers, Racer Elites & Racer Trainers equipped with a single strand adjustable main lift web." I've never seen a Racer with an adjustable main lift web, but it sounds like the newer system has more layers of webbing in it. Pictures, anyone?
