  1. If you need a motor I would reccomend one of these. I have one on my 2 needle. No clutch, it only runs when you need it to and the speed is easy to control. https://atlaslevy.3dcartstores.com/Premiere-CSM550-Variable-Speed-Servo-Motor-_p_103.html It will mount into the same holes as a standard clutch motor.

  2. Yes, pics. Sewing machine motors can be 110 volt or 220. I don't think they would ever use a 3 phase or anything exotic like that. But 220 is very common in factory sewing operations. There may be a wiring diagram inside the connection cover. You can buy a brand new clutch type motor for less than $100 and even better, a servo type for a little more than $100.

  3. That would not explain reserves opening too late from AADs firing at terminal velocity. Do you think that those are basically caused by late firing for whatever reason? The recent Florida double fatality comes to mind here. Surely these guys were falling fast enough for there p/cs to be effective. Perhaps it is well known in Deland through the grapevine what actually happened. But out here it's a mystery to us. I guess if I take my choice from your options menu, late firing would be the logical answer. Late cutaways resulting in fatalities are understandable. No pulls or late pulls are as well. But what is the point of an AAD if it fires too late? I have begun scaling freebags from packed rigs that come in for service. But it's just for my curiosity so far. There is no standard I can apply. Although I will be handing out free advise to customers. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  4. So we don't know if these AAD firing fatalities involve p/c launch hesitation related to using a cutter or if they are related to slow to extract dbags. Or both, or neither? And as far as we know no one is looking to find out, or if they are they don't want to speak of it. I guess the closest we can come to an understanding is that there is a move by the industry to raise activation altitude. It may go a long way to solving the problem without anyone having to acknowledge that there even is a problem. Oh well, sport skydiving is a risk activity. The main public exposure is through tandem where the rules keep us safer. Maybe we have no right to expect more from the PIA. I'm guessing there are many within the industry that understand exactly what the problems are. Maybe Mr. Sherman has been correct all along. Even if he does sometimes sound like a conspiracy theorist. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  5. Ok, I've got it. It is not a ballute. And I've done some searching and now see that the controversy between Bill and John over p/c design is old news. I'm sorry I brought it up again. I still would like to know why we have had so many too late to inflate reserve fatalities after AAD fires and what we can do about that. There is no investigative body to look at this. I'm sure there are people who know, but none are saying. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  6. I shoot Nikon, but I`d be surprised if Canon is different. Exposure should adjust for each shot in a sequence unless you go deep into the menus and set exposure lock on purpose. You can also choose to have the focus lock with the button pushed, which you might want to do with autofocus if you have a large depth of field setup. Otherwise many cameras will slow down while they decide what to focus on. You are probably wanting to shoot rapid "spray and pray" frames. Sometimes this works, but many times composing the shot you want is better. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  7. Which makes me wonder. Why does the Racer have the p/c on the outside? Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  8. Now that's got me wondering. I can see intuitively why a p/c that is shaped like a parachute could be more effective for the size than one shaped like a balloon. Has anyone ever attempted to make a man sized balute type parachute? Would the oscillation be extreme? Always remember the brave children who died defending your right to bear arms.

  9. Once for a friend's 100th we had him climb out of the 182 first. We told him he had to get waaaay out there to give us room. When he was out there we climbed back in a closed the door leaving him out there alone watching the airport get further and further away till he finally left alone.

  10. Sandy, A G-10 is a point and shoot and they aren't designed to respond as quickly as a DSLR. The SL1, and any other SLR uses TTL (through the lens) exposure control. Meaning that the camera decides on the shutter speed based on the actual conditions when you release the shutter. (when not set on manual shutter control) Using a wide zoom like 10-17 should allow you to use the widest setting with the lens on manual focus. Just find the place where the nearest important element is still in focus and infinity is as well, the range is huge with this type of setup.

  11. That is interesting, but it only tells us the difference between the three different products in one sample in 1988. I agree that the Racer system has several advantages in regard to potential speed of reserve deployment. But it may be that it is the Racer p/c that is the outlier in terms of extraction ability. What I'm wondering about is not the already proven difference between Racer and everything else, but the difference between Vector type and Wings/Javelin ect. type systems. I suppose in the end that the force generated by a sub-terminal cutaway may be a lot more important than that generated in a wind tunnel at high speeds. Although the fact that the drag increases by the square of the speed would seem to indicate that one can predict the other.

  12. I've not actually seen an Infinity p/c, but I've seen many Wings and Vectors. In what way are these two similar? They look to be very different to me. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  13. 1) Yes 125 mph wind is quite noisy. After the parachute opens people find the difference startling. 2) Only in very warm places would people regularly jump in just shorts. That advice probably is given for a place that is selling tandem jumps, and is likely based on wearing a jumpsuit over top. Although it is generally warmer than that at 3500 ft, most jumps are from 11,000 to 14,000 ft. Conditions vary like the seasons, but can be very cold at times. 3) In soft ground a falling body is said to leave a "crater" Always remember the brave children who died defending your right to bear arms.

  14. Poptop safer? I don't buy it, epecially the "semi poptop" rigs. The reason is that although they likely will get the p/c into the air faster without having to push flaps aside, that doesn't seem to be the current problem. The problem is rigs that are slow to extract the bag once the p/c is in the air. Rigs that have the p/c under 4 flaps have large strong springs that do the job, it is a non issue. They also have larger p/c s that I speculate (yes, I expect to hear opinions on this) are capable of generating more force from less airspeed than the smaller ones used by the more exposed versions. What good is it to get it into the air if it doesn't produce enough force to pull the bag out of the tight container? As far as I'm concerned. the Vector balute type p/c is the best at this, it works even on large Sigmas. Talons also have large ones. I feel that looking at your p/c cap on the outside and thinking that it makes you safer is a false premise. I will grant the the Racer solves the problem by eliminating the tight container. Does anyone here know how much force is generated by a Vector versus a Wings p/c? Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  15. And only 150 eur extra for this minor change to the software! At that price I think Airtec will not be taking much market share away from AAD who's Vigil has long included the same feature. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  16. Easy to fix. A little heat from a butane lighter will clean up that fuzziness nicely. (kidding) Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  17. They are dated by month and year of manufacture. They aren't cars, they don't have model years. If you buy one in Jan, it will almost certainly be dated from last year. They are good for 20 years. Will you still be using it then? Buy it before you need it so when it comes time, you have it in hand.

  18. Wait a minute. Didn't this thread start off with you asking about a Raven that opened hard routinely? And that you have tried everything you could think of and were out of ideas? And that now you are considering slider mods even though you have already tried a larger slider? You are the one saying it opens hard, aren't you? I'm just trying to say that your dad deserves a canopy that doesn't hurt him. Super Ravens are known to open quickly. They are also known for '80s style flaring. Good luck with statistical averaging of the pain and injury, and good luck with your dad's "classic" canopy. Always remember the brave children who died defending your right to bear arms.

  19. This would be exactly why 500 jumps may not be enough. If you had more experience you probably would have handled the situation better. I'm not saying the number should be raised, just that everyone considering taking up tandem should be aware of the challenges. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  20. Another way of looking at this is that nearly 10% of the those openings were dangerously hard. Not exactly a ringing endorsement. Just saying. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  21. Weren't those just installed on the early Ravens? After the (b) series the design was changed to make them open faster. That's why no more bikini slider needed? Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  22. Thanks. That was a bundle of help. When you have been in the sport longer than he has I am sure he will welcome your canopy advice. I am asking a legitimate question about how to slow the opening of an existing canopy. While I'm sure there are some out there than feel a guy with 40 years in the sport "ain't shit" if he isn't jumping a 60 sq ft canopy and swooping a pit of crocodiles, I feel I should point out that gear selection is a personal choice and he likes the raven. When it was ordered he didn't realize the microline would cause such hard openings. Short of relining the canopy I am simply asking if anyone has some actual helpful advice as to how to slow the openings. Raven? 40 years? So what. Does he drive an car designed in 1980 and expect it to act like a new car? Just because he used to own a bunch of bagged out f-111 type student canopies that opened fine is no reason to believe a new Raven will open nicely. Ravens open hard, always have. When his gets 3 or 4 hundred jumps on it and becomes bagged out it will open gently. The year is 2013, he doesn't need to do that anymore. Why dick around with slider mods trying to make a silk purse out of a sow's ear? He deserves better, he's earned it. Always remember the brave children who died defending your right to bear arms.

  23. Interesting, especially the comments on pull testing, which I have always thought to be too destructive to use without a clear reason to. However, if you are talking about the clamps pictured in the FAA manual and the RI packing manual the clamps used are clearly "Pony" brand soft rubber tipped 4" clamps. Originally intended for wood working without marking finely finished surfaces. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  24. Eloy has the most reliable weather and the best potential for the most jumps in the least time. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
  25. You are wrong on both counts. Period. Always remember the brave children who died defending your right to bear arms. Freedom is not free.
