    Student canopies

    This is a good idea, and in fact we already have some small rigs for small people. At the moment they contain Fury 220's, but we will also replace them with (probably) navigators. We already have some Navigator 240's, and the plan for now is to replace the Manta 288 with Nav 260's. So in the near future we will have 1 type of canopy in diffrent sizes... I like that.
  2. I have / had 1 Hypeye on one of my X3000's. It stopped working after just a couple of jumps, in one case it showed a red light while nothing was recorded.... during a competition.... thanks to the backup I still had video to show to the judges. I think the micro usb connector is way too flimsy.
  3. Hi You do not really need a DSLR for rw jumps. Sure it is nice to shoot some stills once in a while, but I usually prefer to avoid the added strain on my neck. It is also something that you can add later, after you get some experience. You do need video. For competition jumps it is usual to add a backup camera, in case one fails. For camera choice, many use a gopro 4 or 5 but I really like my Sony X3000. The stabilisation makes the image super smooth, which the judges seem to like. By the way I'm in Holland, I'm kind of curious if preferences are different elsewhere.
  4. No, it is the rejection of certain claims that cannot be backed up with objective proof. So it is actually the opposite.
  5. Since I helped to derail this thread a little, it's only fair to get it back on its original track ;-) You have probably already seen this, but in case you have not; how about this one: https://www.marktplaats.nl/a/hobby-en-vrije-tijd/naaimachines-en-toebehoren/m1191424268-naaimachine-pfaff-262.html?c=8c285449651fa109c354bbabe740c1b&previousPage=lr&pos=1
  6. If you are wondering about a servo motor for your Singer 4432 then you need to learn a little more about sewing machines. If you can, visit a rigging loft and get friendly with a rigger there. Ask to see machines and ask about the different jobs each one does. If they have time most riggers love to talk about and show off their sewing machines. Maybe I was a little unclear. I don't think a servo is an option for a 4432 - but one of the previous posters seemed to hint in that direction, which was surprising to me, hence the question for more info. I fully understand that the 4432 is a POS, as the OP stated, but it matches my sewing skills and, for me, it is good enough to repair the holes in my jumpsuit. I just wish it could sew a little slower.
  7. Stop being a whiny little bitch. Putting a servo motor is a 15 minute job, and everything fits like a glove. It solves your slow speed problems, and unless you are punching through 5 layers of leather, this will work excellent in 99.9% of parachute work. More than one person told you to get a servo, there's probably a very good reason. So : Stop being a little girl Get a servo Be happy I have the same machine and the same problem as mr. IJskonijn (who, I can assure you, looks nothing like a little girl - except the Sinead O'Connor hairstyle maybe hahaha). So where can I get a servo for this machine?
  8. Well, as an atheist, even I must admit that I can't prove that god doesn't exist. Plenty of evidence (that you can check for yourself) that the world is in fact a globe, so regading flat-earthers, I would vote for "more stupid". Very entertaining tough :-)
  9. How can you not see the irony in your totally random number of 50 jumps? It's not fair!! I'm used to using camera's!! hahaha
  10. It's a good question. For me, I always interpreted it as "the moment I let go of my hackey". I also agree that it shouldn't matter much, in most situations at least.
  11. I agree, video is an extremely powerful learing tool, both for freefall skills and for landings. This does not mean that the person that needs or wants feedback (the "student") needs to be the one handling the camera. In other words: ask one of your friends to film your landings from the ground. Then ask a canopy piloting guru to have a look and give you the feedback you want. Outside video gives a much better perspective. If you doubt this; why do you think my FS4 teammates pay for my jumps during training, so that I can film their jump as an outside camera flyer? Being a camera guy means I have a lot of my own landings on video. Frankly this is nearly useless and I still hire a canopy coach now and then for video and feedback.
  12. I use a ProTrack but is has the same option. Downside: it may log a descending airplane as a jump. For instance, this can happen due to sudden bad weather or low clouds. So basically you end up with the same problem with your logbook. You will have to guess which of the two will happen more often.
  13. For RW filming I am very happy with my sony X3000 's; image quality beats both my old CX105 and GoPro 4. HypeEye alpha makes control super easy. Good battery life (can easily film a full day jumping on one battery) Less than half the weight of my Cx105. So far no software problems, crashes, or lock-ups (very much unlike the GoPro). I don't think a big camcorder will give much better results. But then, I only do RW at the moment, and I am curious to hear what others think.
  14. Thats a terrible excuse for yelling at other jumpers and forcing them to sacrifice their own safety. Assuming you didn't mess up your count I'd say you did exactly the right thing.
  15. well... it seems that Fox is not alone. Not sure I believe this, it's almost to funny to be true... http://www.businessinsider.com/trump-support-climate-change-open-letter-2017-6?international=true&r=US&IR=T
  16. I really like the Sony x3000 because of the image quality, the stabilisation, its shape. And let's not forget reliability. I've had lots of issues with GoPro's, like getting hot, draining batteries, freezes, suddenly not recognizing the sd card. And they are always updating the firmware in order to fix bugs. With Sony.... it just works :-). So far at least.

    Student canopies

    Thanks a lot for the detailed response everyone, this is really interesting to read and very helpful. We do that too for our Mantas and Furys. It works relatively well, but one of the downsides is it reduces the responsiveness and flare, especially for people with shorter arms. What surprised us was that the Navigator 260 was very responsive for even small inputs, yet we were not able to stall it. Even when we let a big guy jump it with a weight belt (15 kg if I remember correctly), so exit weight probably around 125 kg (275 lbs).
  18. True, but not uncommon. Maybe not your OWN lines, but how about a canopy collisson? And there are plenty of video's on YouTube where an aff-I catches a students bridle with their GoPro. They usually manage to disentangle or release their helmets... not an option if it breaks your neck first....

    Student canopies

    Hello all, My skydiving club is looking to replace our fleet of Manta 288 canopies within the next few years, mainly because they are getting too old. There are lots of options available. I jumped a Navigator 260 last weekend and I liked it... Mainly beacause of the much better flare and responsiveness to toggle input. I did not like the fact that it also responded fairly well to harness input, unlike the Manta. Terminal openings are a lot less painful tough :-) So basically I am looking for options and opinions... So please share your thoughts!
  20. *** Step 1 is to get used to having something on your head while still keeping your mind to the jump and not to the camera. I think what people are trying to say, is that training to ignore the camera is not neccecarily the best way to go. This will work for some time, but there will come a situation where you get mentally sucked into focussing on the frame or on whatever. So maybe do this for just one or two jumps, and then take another approach and do almost the opposite: consider the camera as an extra task, which you plan for, and are fully aware of. This assumes that you are somewhat compentent in freefall and are able to handle the added workload. In this case you could start with filming two-ways or even solo's. Make a plan, and discuss it with everyone involved and at least an experienced camera jumper. Not all intructors will agree with this approach and it does not apply for all kinds of jumps; alway discuss with your instuctor before doing anything stupid :-)
  21. I have seen (while I was standing on the ground) 4 side by sides, all of them as a result of a low-pull. Two big canopies (student, navigator 240 or manta 288) and 2 experienced jumpers during bigways. All 4 seemed to fly pretty stable, with no tendency of the canopies to separate or fly into eachother. One cut away, the others made super soft landings. So my question is: why would you risk the main risers damaging or entangling with the reserve by cutting away when you can safely land what you have? Seems like a big risk without benefits to me. As for which risers to use to steer the two canopies; I tend to think that you will find out soon enough if you carefully try. If the canopies act funny: try something else.
  22. Follow the money, OK. Oil companies have huge reasearch budgets and every reason to deny any bad consequences of their work. They employ lots of scientists, who have a direct ecomomic reason to deny climate change. They have an enourmous political lobby. They pay large amounts of money to get their favorite politicians elected, especially in the US. So if you want to follow the money, why not start by looking in the direction where the money actually is?
  23. First of all, your youtube channel is very cool, nice to see your kids getting involved in technology and having fun with it :-) And sure, you are welcome to use my work. I put the sourcecode in a dropboxfolder, I think it explains itself (mostly). https://www.dropbox.com/sh/1z9c3vnruzqz8m7/AAC8BXlM4-yZY7q9zuowCDtNa?dl=0 Yes, I used an ESP8266, programmed it with the Arduino IDE. You will need to download some additional libraries. I used the Wemos D1 mini board because it has everything (including USB) on its PCB. But you can use any ESP 8266 board, as long as it has enough IO. I considered powering it via a LiPo battery but for now it is powered directly by 3 AAA batteries. The display is a 1.3" Oled. Let me know if I need to explain anything else. Good luck!
  24. Thanks for the compliments :-) But no, I don't want to sell these, I don't have the time right now. Maybe in the distant future. On the other hand, I would be happy to share the design and the software with anyone who wants to try it. Its not hard, it just takes some DIY skills and time. So just let me know if you are interested.
