  1. The best person to answer the question is Tom at Sunpath. I have supplied quite a number of pilot chutes to individuals and it isn't the first time I have heard of this sort of thing. SunPath calls for a larger than average PC. Not everyone agrees to use the recommended size, but for those experiencing lazy extractions, a new PC has always resulted in the problem going away. More than once I've loaned a replacement PC when someone felt theirs wasn't worn out, and funny thing, they never ask to have their original re-installed...

    Microraven 150 @ 1.25 WL

    I hate having that discussion with customers. It is always my choice to not pack that micro raven 120 for a 200lb guy. Unfortunately they just go find a newbie rigger and off they go. Going against manufacturer recommendations is poor risk management. I own 2 optimums and a PD-R. I know they test their reserves more than others and have the largest R&D budget. In addition, the gold standard for reserves makes them a lot more resalable when you eventually downsize. Another small side effect is that riggers are most comfortable with packing the most popular reserves. Get an oddball one, they may not be packed as neatly. Should we talk about flight concepts??? :( -Michael

    New AAD made in USA

    I think your project is really cool, and it's been quite some time since I first saw you were working on it. While I don't love the shape, especially for those of us with smaller rigs, I believe the final production version should give you the ability to shrink your design. Battery technology and processors continue to shrink in size. I look forward to seeing this product make it to market. -Michael

    Why does this happen the day after I get one of these? -Michael

    PIA Rigging Symposium Chatanooga

    I might be up for that. I'd PM, but your PM's are turned off. -Michael

    Any experience with a Firebolt 180?

    I would suggest you have the trim checked. We have a firebolt 189 at the DZ and I load it around 1.1. It's been a few seasons since I test jumped it but I found the flair to be quite acceptable, far better than my triathalon. -Michael

    Vectran reline

    Depends on the size. I'd tend to go toward the 750. I thought I recalled that their lines were normally HMA but I'm not sure. -Michael

    Excessive twists on bridle

    I've seen it before a few times and in each case it was that the PC was not completely collapsing. You can pull the apex out to the limiter tapes and make sure you don't have more than 1/2" of slack on the kill line. Also, make sure the bridle is installed correctly and that the kill line can travel unhindered. -Michael
  9. There was an article posted on the main page about buying gear. It has some helpful hints. I don't recommend buying new gear unless you have 1-2 seasons and/or 100+ jumps but others' advice may differ. Buy something used and resell it after a season or two. If you really want new, that's the time to buy it. You'll lose a couple of dollars per jump you put used gear. New gear is like a new car, first jump it's depreciated a grand or so... It's also a dirt magnet. When you have a couple hundred jumps your gear will stay considerably cleaner. -Michael
  10. Sometimes I can't help but to feel like posts like this using an account with 1 post are put up by those behind a product as an advertising means of introducing it. On that front I'm already not feeling positive thoughts about a product/company. The device looks OK and I think there should always be room for newcomers to the market. Their products always need to be sold for a considerable discount below the established players. Devices like this cost almost nothing to make but the margin pays for R&D and support. A company like L&B can produce thousands of devices at low costs per unit but they have the staff, experience and engineering to ensure there is someone who can repair, recalibrate and provide whatever support you need in the years to come. I've been using my altitrack for 8 years so far. On that point it has to be cheap because I don't know if the company will be around in 2 years or 10 years. -Michael

    Endorsement for Saxx underwear

    Haha. Thanks for the laugh. A friend was just telling me how they were expensive but worth the cost. Who would be willing to approach saxx about some underwear freefly jumps for their commercials? Floppy skydivers need not apply... -Michael
  12. Only 1 suggestion to try other than calling PD. try lengthening the brake lines and shortening the part below the cat's eye. Basically make it open in less brakes. -Michael

    Flying High - Sidewinder - TSO

    The Sidewinders that are TSO'd are no different to an FAA rigger than any other TSO'd rig. The case where non-TSO'd gear comes in is that a US jumper can't use non-TSO'd equipment but as a non-USA jumper I can jump my Arrow (non TSO) rig down in the USA all I want because I'm a "Foreigner". -Michael

    White or glowing face for first altimeter?

    Go check out all the options, try them on and decide. Glow in the dark faces are something you're not going to use more than a few times. 0.3% of my jumps are night jumps. Maybe 0.5% could have used the backlight on my altimeter. In other words, not high on the priority list. -Michael

    Check your webbing!

    Yay for macro lenses and 50 megapixels! This is what you don't want to see on one edge. This is what both should look like. It's zoomed in a lot so you can see that the fill yarn alternates around the warp with every pass instead of simply daisy chaining like on the image above. The best way to do it is twist and compare side by side. The grey is class 1 the black is class 1a. -Michael

    7-33 hook shape?

    The needle is new and I've buffed any nicks on the hook. The tension is also correct. The needle height is correct and timing is not adjustable (it's correct anyway). The bad stitches I show occur only about 1/50 stitches. The sewing machine mechanic said that's the best you'll get for a 60 year old machine but I know better. When you look at the bad stitches it's almost like they're extra twisted. The thread 5 cord purchased from Paragear. I'm feeling like this is pointing to the hook. It is about 0.010" from touching on the downstroke and there is about 0.100" as the hook passes the scarf. -Michael

    Juki LK-982 bartacker

    They are quite easy to time if you know what you're doing. I'd say they are as easy or easier than any other sewing machine... -Michael

    Rigger named Alex in 720 area code?

    Hey baby, I got my lap rating. Want to try it out? Ok, more seriously, are there even any lap parachutes out there? I've never even seen one before and I've looked at a number of the old stuff Vintage Wings flies from WWI and WWII -Michael

    Rigger training aids?

    I have offered a bunch of our worn out drogues to Frankais. Do you need some too? I think a sample of lines would be useful too. I can try to get some good and less good and set them aside next reline I do. -Michael
  20. I'm not sure about Iota specifically but I kickstarted a high power bluetooth tracker called stonetether but got screwed. It's continual promises but no products. Instead I just got a tile and have been testing out the range. I think it's a viable solution. Next step will be to design a long range antenna and see what sort of range I can get. -Michael

    4 Smart Questions That Shut Down The Spin Cycle

    Interesting article but I think it misses some of the most important parts about harness/toggle symmetry that cause the spin in the first place.

    Jumping with a bicycle?

    Rob you're too old to become a dirty rotten low pulling base jumper. Now, I have seen some bicycles that fold up to be put in a trunk that might suit your needs. I'm always nervous about these kickstarter things but you might want to check out a helix bike. I saw photos of a prototype that was to be folded up in the back of a carbon cub. Other than that, check out a dahon uno they're not made out of unaffordium and you can find them on amazon. -Michael

    Singer Class 7 harness machines

    I was considering picking one up but after hearing Jerry talk about what his 132-K6 was able to do I'm not sure anymore. The other consideration is what my will might be able to do to my knees if another machine shows up here. Do you have the machines yet or are they en-route? -Michael
  24. We have a few vector SEs and our DZ is also sigma tandems so there are a few advantages with respect to ordering parts. We also have some Javelin rigs equipped with skyhooks. I can put parts orders in together as well as stock reserve pilot chutes and a collection of sigma and student freebags then assemble them if needed. First, I believe MARD systems are a good thing for student operations. The Skyhook system is well tested and if you ever end up in a legal situation there is some strength in saying it's the best tested, oldest and most used system on the market. Finally, for me personally, I like the Javelin but not all riggers are good at or comfortable packing them. It is also nice that they all use the same freebag stow so despite it being a manufacturer only part I only have to stock one size. So make sure whatever rigs you choose are something the riggers will be able to live with. Hope that helps -Michael

    New Product need support

    There was a guy who was selling them a few years back. I lost mine when my car/rig/everything got stolen (parked in the wind tunnel parking lot) :( Boo. I'll have to ask around to see who it was but the pack was pretty nice for $80. -Michael
